Wonderful, a video that answers all my questions about shop power supply!! Love your videos. As a new machinist, I learn a lot from watching your work and shop talk episodes.

Much appreciated. One of your best videos, lots of great info. Thanks. I'm building my own shop now after retiring from many years in the industry. Looks like the size of my shop will be very similar to yours. Seeing what you've done gives me confidence after worrying that my new shop might be too small.

Hey Adam,loving the shop talk videos. Keep up the good work and stay safe with the incoming storm.

Thanks Adam, another great vid. Carbide is a wonderful thing, appreciate the lessons on using it with the big stuff. I have the smaller lathes with belt drive so you mentioned a different rake. That 3ph power story worked out well for you for sure, makes many of us out here with our converters wish we had it. You have bombed youtube with vids since your first introduction, GOOD on you man! Keep up the good work.

Very informative video. I really enjoy the shop talk series. I have always wondered about the service at your shop.

Good damn video...and lots of good information Thanks for sharing Manny

Highly informative! Thanks Adam!

Adam, the concrete slab in the shop was badly poured. Too much water was added and the surface was over troweled. The fine cement particles separated from the sand and aggregate and formed a soupy slurry on top that is not well bonded. That's why you get so much dust and the surface wears so easily. You will need to remove that layer of fine dusty cement from the surface before trying to seal the slab. There are mechanical methods to scrape it off. You will need to etch the concrete and use degreaser and remove any oil to get a good bond. I think a good quality concrete paint would work better than a sealant and will only need to be touched up occasionally. You can mix some ground walnut shells in the paint to get a non-slip surface.

Im very new to working with my lathe and I really dont understand all the different numbers to use with what tool but I watch your vids which helps.

Good video, Adam. Hope you get through this storm OK.

Hi Adam, One way of sealing powdery concrete is to use Water glass - Sodium Silicate. If you're up for an experiment, you can even make your own from the desiccant bags you get shipped with stuff and Sodium Hydroxide - Lye.

Hey Adam! You can allways build your own beltgrinder. It would be a lovley project for your shop todo. Its some grinding, welding, lathing etc.. If your interested , Ill send your more about it!?

Thanks for the info Adam... Very helpful!

Thank you. Your insert videos should be on a separate play list.

Another great video. I wish I could get 3 phase into my garage. Phase converters and VFD's for now.

Take care big dog. My thoughts are with you and your family during this bad weather.

@Abom79. Thanks for all the extra videos this week. I am loving them. I would love it if you would post short videos more often. I know it's a lot of work, but coming from a guy that doesn't have cable TV, content like yours is a valuable commodity. Thanks for all you do!!!!

GRACIAS POR ESTOS VIDEOS Y GRACIAS POR PONER LAS CARACTERISTICAS DE LA CUCHILLA!!👍👍

Another great video. Thanks!

I have used a few different Ingersoll inserts quite a bit for 316 stainless and I like them. Never tried these VF ones though but now I want to. I like finishing with DNMG instead of CNMG because unbroken chips often get stuck between the insert and your work piece with CNMG.

Enjoying the shop talk series. I did urethane sealer a few months back, and have been very happy with it. Here is the video i did on it in case your interested.

good stuff man,great insert info

Me gustan sus videos son educativos esperó que siga así abrazos desde República Dominicana

love the videos keep up the good work

great video and as always very interesting. thanks for sharing :)

brilliant shop adam well done

we use DNMG-R 432 every day for long narrow turning and never have problems with chatter. I am a firm believer of these inserts. nice and smooth. we turn a lot of 303 316 and 17-4.

Nice on the direct full 3 phase power. It is common for businesses to have to get an engineer opinion from the utility. After all they spend a lot of money to install and maintain that gear. Yes, you are fortunate to have that available. It is always worth the while to have an electrician who is serious about doing it right too. Great stuff.

I Have That Same Sander For Years . I love it, Well Worth The Money. The Only Thing I Did is load the bottom with Weight.

The sharper pair of inserts might be for aluminium. Granted shop class was a long time ago, but i remember the teacher explaining that the sharper edge cuts the Aluminium better, and that it wears out quicker if or breaks the edge if used on harder materials like steel and stainless

Where I used to work, we had an old cast iron Craftsman belt/disc combo and it might have been the most used machine in the shop. First thing I did when putting together my own shop was to hit craigslist to get one for myself. At the moment I am thinking about getting another one for a different shop. With a belt drive, you can easily size the motor and speed you need. I notice that some of the imports are direct drive, with 3450 or 1725 motors for wood or metal. I like the idea of a belt better. It also lets you put the motor out of the way. There are so many good old iron ones out there, from a lot of brands, that would be my first choice. I did have to make a new roller for mine as the stock one was a die casting that had cracked. I just made a replacement from solid alum bar stock. I think Tom Lipton made his belt sander from scratch, if you are looking for more shop projects. I would make my next one, but can't spare the time, so craigslist here I come. The old ones seem a lot more repairable, while the new stuff is more disposable.

Can't go wrong with an Ellis belt grinder, had one for several years without any problems and do a fantastic job!

thank you Adam I have never ever text you and watch you for years thank you for that one

I've never used a Rockford belt sander but I did have a used kmg belt grinder back at my old shop and it was a very good machine. I had to replace the motor when I got it but the machine itself was well made. But with your machining and welding skills it wouldn't be to difficult to make your own belt grinder, there are tons of plans online for them and the wheels and bearings are readily available for them as well. It would be a long project probably, but not a difficult one for a machinist of your caliber. Or you could make a belt grinding attachment for one of your bench grinders, that would be almost trivial, a bar with some support trusses, a bolt pattern to bolt where the wheel guard goes, and a drive wheels and idler wheel with a tensioner arm.

Hey Adam. I just checked what I've got at work & it's a jet model no: JSG-6DC has 6"x48" belt & 12" disc. It has been put through very serious use for 15 plus years now in our fab shop & has taken every thing we've thrown at it. Down fall is it's like $1200 bucks.

Hey Abom. About the sealant. You might wanna ask around some concrete experts to see if sealant or paint would work better, sealant might not work very well if there's any oil on the floor. I imagine there might be, what with it being a machine shop ;)

Just a thought or two concerning the Kalamazoo strip sander. A local machinist friend of mine built one out of stuff he had laying around, only his is a lot better. He has a small table on it but can fit a larger table to it and he made it stout. The vertical strip on the front is backed by a plate to support the belt, but there is access between the top and back wheel that is not backed to allow the belt to flex, which is handy for some types of sanding. Instead of two wheels his has three and they are all different diameters and you can easily get to them. This is a little more versatile and is very handy and takes up less shop space than a couple of strip sanders to get those diameters. The three wheel assembly can pivot concentric on the drive wheel which is the bottom wheel, like in the photo of the Kalamazoo sander, but the whole assembly can pivot forward or back to gain better access to any of the wheels. This also allows the backing plate to be horizontal which can be helpful at times. Just thought I'd bounce that off of you. I really don't know if you would want to try a project like that or not but his has served him very well for around 30 years of use. He ran a job shop out of his basement. I haven't seen him for a while but I may try to get you a photo of it if you are interested.

Thanks for touching on those inserts adam!

great video , thanks

Hey Adam nice video and yes you are lucky to have 3 phase power I also have 3 phase and it is great to have machines run a lot better on real 3phase. I had single phase power 6 years ago and I had a rotary unit and it worked ok but were good now.

Outstanding video, very informative and entertaining. If the topic comes up could you go over your compressed air system, what tools you run with air and what size compressor you would recommend for a small garage shop. Thank you from a very amateur welder(mostly grinder) / machinist.

From one Adam to another, I approve of your Mancave rules :)

Hope you are ok with the weather over there in Florida Adam

Very, very good shop talk Adam. I actually knew generally what you were talking about on the inserts, having caught some of Keith Fenner's footage where he was talking about negative vs. positive inserts and also him ranting and lamenting in one of the 'Wing It' vids how stand-up, positive threading inserts (I think positive) are getting near impossible to buy and he prefers them because of his lathe's cross-slide nut and screw having so much slop in them. Incredible you were able to get three-phase power run to your shop without having to pay an obscene extra price for it! Of course, having 6, now 7 I think I counted, machines, including the air compressor, all needing three phase power and they can count on those machines being run in the evenings and on the weekends fairly regularly, it was a three-phase connection that was going to be used good and regularly. ^^

Hello Adam, Even if you just replace your bulbs with the 7000k as they burn out you are ahead. I haven't found them any more expensive just harder to find. The leds are made that will pop right in to your present fixtures. Costco had them last year both as fixtures complete w bulbs ($50) and as led to replace drop into existing fixtures. Take care. Doug

I like the walk around the shop. I am not as lucky as you are. I have to have converters. It is no big deal I just cant the full HP out of my mill.

I haven't heard anything outright against Rockford but I haven't heard anything outstanding either. I think you're better off sourcing something that was used, like John over at NYCCNC and his last bunch of acquisitions. Something with character that won't feel out of place with your current equipment. I'm sure if you put out feelers something better than that will pop up.

nice one Adam, i wish one day i could visit you and the shop !! and by the way your neighbours trees worth to CUT !!

olso a good movie.. tanks adam!

Awesome man, I always wanted to see whats infront of the shop, glad I could "walk" with you out there. =D

Adam I've used that model 2" Kalamazoo belt sander, they work really well. We have a newer Wilton like KF, but instead of the disk it has a chamfer cutting setup. The belt sander portion works well, belt tracks nice, and the unit is fairly solid. I think so many people asked about your power because it's so rare to have 3-phase at your house in the states anyway.

Also, I'm personally not too keen on belt sanders but it looks like its got a disc sander built in which is always a great bit of kit!

I'm wondering what that loudspeaker above the roll-up door is for.

Just seen footage of the hurricane damage in Cedar key, I hope it's not that bad in Pensacola. Great video as always.

Dang, that is a nice shop, Adam! Terry Cullen is correct; the sander is not very sturdy. PS: For fixing the concrete floor, polyurethane coatings aren't inexpensive but they do last. And they *stick* to concrete forever. They aren't as hard as epoxy, but they don't chip or flake off. I've used them for outside waterproof treatment of concrete decks. The waterproofing treatment is a low durometer stretchable layer covered by a harder wear layer. For a shop floor, the top coat hard wear layer is all that is necessary. Marble dust, ground-up rubber or sand can be cast on the wet urethane for a non-skid surface. Pacific Polymer and BASF Sonoguard make excellent products. It's an expensive product, but you will only once.

Take a look at the Stephen Bader B3 sander, a little on the pricey side but they work very very well. Can quick change the belts so you can have roughing belts all the way to scotch brite sitting next to it.

In my shop we mainly stick to tnmg inserts for majority of the work. Still has a 60deg tip, so some rigidity in the cutting edge, and 6 cutting tips so cheaper overall. Unless the part geometry requires deep undercuts we'll use a D or T. Sometimes for heaving roughing we use the 100deg corner on a cnmg for straight faces or diameters, that thins out the chip and allows for deeper depth of cuts. 0.4" depth of cut with a D is really good in stainless, and with a 3/4" holder too I'm surprised there wasn't any vibration or chip breaking issues.

Love the shop.

I'm far from an expert on sealing concrete but if you care about the finish you will want to do it in one pass or feather it out really well, which is hard to do with a 2 part sealer due to how thick it is. The other thing that will make using a sealer painful is the cure time. 24hrs to recoat on, 30 days to full-hard according to the PPG rep I spoke with about their aquapon. The other issue you may have with it is that it is not good for use around hydraulic fluids containing phosphate esters, but I doubt paints would handle that any better.

The power thing is kinda interesting. For me as electrician it is interesting how the grid works in different countries, here in Austria or hole Europe we have 3 phase power in almost every household, the most non commercial users don't necesserily using it, but it's very handy if you run a shop, or whatever thing that needs alot of power. ;)

Hi, Adam- We ran a Kalamazoo S660MW, 6" wet belt sander in our production metallurgy lab and it was wonderful. It can be run in the vertical mode too. There was no splash and it kept the samples cool. I think Rockford and Grizzly machines are good, but have no personal experience with their belt sanders. I'm thinking that your friend Keith Fenner has a Rockford machine. Don't overlook the abrasive- the premium Norton and 3M abrasives outperform ordinary aluminum oxide.

have you ever considered doing some live machining? that would be pretty cool. thanks for the videos man

I never see those style of insert listed. Always the standard fare of CNMG and TNMG. Gonna have to do some digging around and try to find some. I like the positive cutting especially on smaller lathes. Negative rake and tool pressure on little lathes makes them bend like spagetti.. :-)

I've got the new MSC flyer that came yesterday and lookin at that Rockford right now. It looks a little chinsy if you ask me. We've got a JET at work and an older Rockwell and the table on this one compared to those, its thin. The belt tracking mechanism at the top looks flimsy and the casting that holds the disc table up looks kinda small as well. I'm wondering if it wouldn't hurt ya to comb craigslist in and around the FL/AL/GA areas for an old powermatic or rockwell unit. I think you're going to be much happier and might get something for less than the Rockford in the flyer. ITs hard when the price is good though but once you got it, you got it since its freight.

why dont you build a 2x72 grinder. would be a nice project for us to watch :)

Great video. I am interested in seeing you seal that floor around all of your machines! Sounds like it won't be much fun. What high school did you go to in p'cola?

thanks Adam , Great shop talk ! I hear ya got a storm headed yur way . Hope all goes well for ya man ! Thumbs up..

Nice shop.

we just used PVA glue on our floor at work seemed to hold up alright

Thanks for sharing ;)

Adam you got a great shop, here where I live if you want 3ph. they charge you commer

Hey Adam,you may want to look at the G0489 Grizzy Belt sander,4Hp 3 phase Bad to the bone.....220v

I have a powermatic model 30 belt/disc sander and it is a very nice unit from the 60's. It is 3 phase and it also has a small dust collector inside of it. They were available in single phase and without the dust collector. It is a 6x48 belt and a 12" disc. I use it alot. I bought mine in great shape locally and in dire need of one at the time and paid $450 for it. I have seen them go from $150-500. You might consider reworking the belt sander you have and turning in into a vertical mount. Make a new table for it in that orientation. I'd also make it so you can access both sides of it as I use the slack side of the belt as much as the platen side. An advantage is your sander looks to be larger than a 48" belt which will be better. I also have a ww2 vintage porter cable vertical belt sander, if you can find one of these, I'd recommend it as well. They made a few different models/sizes, all nice units.

Hi Adam Great video as usual. WRT the $750 grinder - wouldn't this make a neat winter project?? One could get the building details from Tom (who I understand built his own years ago) and then build one showing the process on KZfaq ? Something like building the welding table or the K & T parking attachment only this time we in KZfaq land could copy what your doing and build one as well Rod

An easy, cheap and fast sealer for the concrete is Sodium Metasilicate aka Water Glass. Home Depot sells it as a liquid concentrate (Armor S2000) or you can buy the powder and mix it yourself. Basically you clean the floor, mix up a gallon and use a cheap garden sprayer to apply it. Dries in a couple hours on a warm day.

Thanx man

Adam, I can't speak to the quality of the Rockford sander but I would say that any newer machine like that will be lower quality than an older Powermatic. My guess is that the Rockford and the Jet are probably made in the same factory in China and just have different labels on them. I can however tell you that you will LOVE one of those Kalamazoo belt sanders. I have the 2x48 model and use it every day. I like the ease and simplicity of the belt tracking and it has a Baldor motor so no worries there. It's as nice as the Baldor sander that sells for a grand and it's less than half the cost. I had the 2x48 Dayton sander before this and it was a piece of junk! The belt tracking system sucked and even though it was rated a 3/4 h.p. it had no ass at all and would bog down to a complete stop. Kalamazoo got it right on this one!

Hi, you hava a nice workshop. Why do you think of buying the belt sander. You can build one from scrach and enjoy your work with it and later stamp it with "Made in my workshop". I'm sure that it's gonna be more durable than the ones in the market. Save most of your money and make it the way you like it to serve your purposes.

I always assumed your shop ran on "A-Bomb Power"! The main problem with the concrete floor is that in Florida they use what's plentiful as an aggregate...sea shells instead of gravel.

Just curious if you have done any spade drill boring as I saw on Bruce Whitham's channel. I thought that was a very interesting procedure.

Nice tour bud. Yeah, lotsa guys with those converters. Nice coup to get real 3 phase. Looks like you have (yet another) weekend honeydo project to remove the unused outside unused conduit...

Love you bro

Adam, I have not used the Rockford sander, but I bought the S4S 4x36 Kalamazoo sander from Enco 2 years ago. That unit has a belt speed of 3600 SFM. That is the lowest I would go for metalworking. I have been very happy with the Kalamazoo unit. A belt grinder would be nice, but for the price the S4S was a great compromise.

Interesting that the VF on that DNMG insert is a very fine chipbreaker, what kind of feed rates do you run with it in the .005 to .010 range I would guess? I forget is your shop 20x60? All this shop vac talk has me really wanting a new one again but sadly I just dropped a couple hundred on shop lights when I found them on sale, sadly i didn't get enough as I bought out all the store had but it is a good start. As the walls keep going up it keeps getting darker in there. I have never had a sander so i can't offer any advice there.

adam i have a jet like that one your looking at the one thing to look at is belt speed my jet could use more speed i also have a 2x 48 kalamazoo i use it alot good little grinder

Couldn't find those inserts available, March 12, 2021. I tried MSC. Interweb couldn't find other vendors.

What are the different types of inserts and what are they used for? (DNMG-CNMG etc..)

Adam do you have 220 volts, for your welders, or just 208 volts off of the 3 phase ?

do you think it will help keep the inserts cooler by putting thermal paste between the insert and holder? As the insert heats up it will transfer to the holder faster.

I would check the shipping cost on that belt sander since MSC nuked Enco there shipping cost have jumped considerably. I wanted to get the Rong Fu 9x16 band saw for my hobby shop when I finally had enough money saved up in my slush fund to get it was when the announcement of the merger was made. I was hoping on one last machinery madness discount so i could get free truck freight. The freight before with lift gate service was around $250.00. Since the merger its now $350.00 !! I still need to see if I can pick one up at there warehouse In Elkhart Indiana since its only 3 hrs away from me.

The inserts you shown at @6.19 are Taegu Tec Brands , I noticed the "TT" symbol marked on side 😎

I would dodge sealing over the welding area, slag chips floor sealant pretty badly.

If u don't mind me asking. how do you have the air compressor hooked up? and do your neighbors complain?

As the concrete is crumbling, I think you should use sodium scilikat. It is so environmentally friendly that if you spill it in the nature, you do nature a favor. And you do not need to do it in sections as you do not destroy any surface it if you step on it when it is not dried yet

Great info, thanks. I am not sure if you mentioned the voltage of your 200 Amps 3 phase supply? It is important when comparing power requirements because you want to compare Watts or kVA needed to power all the machines and lights.

That tank will make a nice smoker ;-) That's what I made mine from, 80gal air compressor tank.

I would try and get a belt sander with a pneumatic drum if you can. The rigid steel drums are crap for knocking off sharp edges and the belt takes a beating from the high point load and chattering when trying to free hand a heavy chunk of metal.

My weapon of choice "Wen available is the Secolor TM4000" it is pretty decent keeping sharp under high temperature... "Never the less this inserts that he is showing/testing are very much out of my $$$ range..

So you folks using 3 phase converters, if you take an old 3 phase motor and put a flywheel of sorts on it, you can use it to generate 3 phase. You can either use a single phase motor to get it spinning, or you can literally kick start it with your foot on the flywheel. once the stand alone motor is spinning that line will generate 3 phase power, even though the motor is only being fed single phase. 3 phase source is only for initial start up. not only is this method cheaper than 3 phase converters, it gives you a sine wave that is exactly like if you had 3 phase source power, whereas converters give you a shit sine wave. You can also use the full power of your machines motor. I believe the motor you use to generate the 3 phase signal must be rated HP and therefor Amperage equal or higher than what you're running off it. It works so well you can use reverse for your brake, just like you normally would to stop a lathe or mill spindle. You can even run CNC's using this method. I'm sure if you google it you can find all the details. I will see what more info i can find and repost it here later, or give it to Abom79 to post. Peace to All

so about your power........ could not resist
