Brilliant! Some basic ideas of things to do would be great next. Not everything you do but some mild porting that you can put back on the saw and tell the difference as a beginner.

I ported my 1970 Yamaha R5 and got 91 hp on the dyno a long time ago. Been using rotary tools of all kind both at work and personally for 40 years and never knew they could bite - HARD. I was holding a stainless steel item in a pair of vice grips using a 1/2 inch single cut ball burr in a big Milwaukee die grinder. My hand was about 4 inches from the work. It jumped and bit my thumb knuckle to the bone.When you said you let it catch your shirt regularly I thought of that. It's such a little tool and the thought never crossed my mind of how dangerous it is until the blood started flowing.

Thank you John for sharing your experience strength and hopes!

Thank you for the no bullshit approach to porting. 🤘🏼

Yo a fool if you're gonna try and pronounce that! I love you John. This channel is awesome.

Thanks for all your teaching and advice, your knowledgeable and entertaining 😀

Great video. Thanks for taking the time to show us what you’re up to.

This is an awesome video, the best way I’ve found for getting the aluminum out is a lye solution, works great if you don’t have a wire wheel. Also, I tried a tonsiled intake after watching your video and I am a believer in it now.

Hi John thanks for sharing your information and knowledge I can see how well organised you are. I have seen those red SR Foredom electric motor online wasn’t too sure about them if any good now that you have mentioned they good I will be purchasing. You make it look so easy when demonstrating porting techniques your using love your ideas. Keep up the good work mate and stay safe.

Great video 👍

Exceptional. Thanks. I'm learning about this to eventually do a few of my own saws. I'll never do it professionally or for profit, but I really appreciate a pro like yourself being generous with your knowledge. You should create a DVD series and sell it.... Basic porting from A to Z

Good job on the dolphin trading video lol all egg yolks aside good info on your tool 👍

I ported a set of 360 dodge heads 25 years ago with a black and decker drill and flea market stones 😆 I show exert cylinder I port up close and personal

I'm a subscriber brother that porting video was great.

I trained many dolphins 🐬 lol I don’t know about porting though 😂

Good review brotha 👏🏼

dip the carbide cutters in transmission fluid then fling off the excess,you have less build up .

Longtime user of multiple rotary tools. Dremels suck in general, went thru many of em before I graduated to big boy rotary tools. I prefer a router speed control switch vs the foot pedal control though, never could get used to the foot control. Awesome video!

Sorry buddy, Donny Walker is the KING. When he's been porting for, literally, as long as you've been alive, you might want to humble yourself just a little... lol

Like it man! When you mentioned the ole shirt snag... I felt that 😅. Better than the ole "i set the handpiece on my crotch with my foot still on the pedal" , that will snap ya back into reality real quick . I like using Diamond impregnated burrs for the last couple tenths of a mm on the combustion side because they won't chip the Nikasil or other plating liners. Great Vid

Hey john! I use the same tools you do, and I use an upside down pop can bottom, and fill it with WD-40, then dip my burs in it (while its turning slowly) occasionally as I'm porting to keep them from loading up. love your videos brother!

Rock on dude!

Jooooosss brow 👍

Cool man 👍🇷🇴👍

For those who dont know, that was a common fisherman knot (proper knot name is "the fisherman") that was holding the grindy thingy in place at the top. Cool trick.

Great video.Thanks.Metric or Standard foredom hand tool .

What ever gets the job done if you need to.. but the quality of the tool usually reflects the quality of the work

My first port, I ported my friends moped with a plug in drill (1980) ... don't edit out that I raised the exhaust roof too much, didn't chamfer the cylinder, and it blowed up pretty quick! Oh well ... saws been doing a bit better.

Great video. The bit I don’t get is how to work out where, what and how much to remove. I will have to watch your other videos to see if I can work it out. If you haven’t done one already a video of what you could do to improve the saws performance by cleaning the ports without doing the full port job would be good.

Good video. Can your 661 series of videos be used as a general guide to porting and polishing a Stihl 193T and 026? I've been wanting to try and port my Stihl saws just to see what I can get out of them. I have all the tools just need to be pointing in the right direction.

Hey John. Just wanted to thank you for all of the great information you put on this video. I have a question for you. I have looked all through eBay and cannot find the really small head diameter 90 degree tool you have mentioned. Is there a specific name I should be searching for? Keep up the good work. Hopefully I will hear back. Thanks and have a blessed day.

Excellent video friend! Right now I am looking for a rotary tool mainly the use that I am going to give it is chrome and to carry car cylinder heads, open manifold ducts, etc. I was going to take a dremel but a friend told me that for the job that I want it has revolutions but not so much power and it ends up burning, what better way to use a drill for that type of work and I wonder if you could use it since the carbides I use to remove metal are 6mm or there would be a lack of power. Regards

Hell yea

Pretty good video kid. It’s funny to hear your story on your first port job with a electric hand drill that’s where I started out 1976 I decided to port my 1975 Honda CR 125 cylinder with an old electric aluminum bodied one speed electric hand drill was it a successful sort of it was probably in my own mind. I swear the bike was a lot more peppier and faster. I even took a little off the head by gluing sandpaper to the top of the dryer for it was a pretty flat surface and I was only a kid and I think I was 13 years old enough of my talking. I enjoyed your video. Thanks.

Hope all is well sir.

I have a cheap Chinese 90 hand piece. It does work but it needed some modification. It did not fit on the flex shaft or accept 1/8” bits without a little drilling. The bearings are a little gritty. That said it does work. I’ve only done a few cylinders with it. Im not a pro so for the price im good with it. I doubt it would stand up to every day use.

Great video check out a company called Goodson I buy my consumables from them I port my own heads for my drag car they have quality product that lasts it may not be the cheapest but time is money.

Do you leave the upper transfer ports alone on the 500i and just do finger ports?

The little yippon for $75 bucks apiece are really great…unfortunately out of 4 two had a ugly thread on the little collets so they don’t screw into the handpieces… still haven’t got back through the allbabba or whatever to get the seller to send over a couple more collets… unlike the quality Foredom handpiece you can’t disassemble to clean and oil…so you just do 5-7 drips through your tool to keep them oiled up… you should oil your handpiece before each use and your spring in your shaft gets grease depending upon your use… I’m every few months… I made jewelry for 20 years before I got into the saw’s 13 years ago… I generally use a little dish soap in a little bit of water as a burr lube that helps them not get loaded quickly too! A old denim… 12” long jeans leg with the top and bottom edges stitched up with a couple bags of dry beans …a little homemade bean bag as a prop pad is a great little thing that anyone with a sewing machine can help with… I used some dry brown sand in one too and it’s good too…. I was really crazy in the beginning and I’d measure the intake window volume and the exhaust port window volume’s with damp sand and a gram scale… comparing their relationship with the cylinder volume and the combustion chamber volume’s… LMFFAO!!! Great video…. I’d probably have to chunk a little piece of 600 in the mandrel and polish that scratch out… one of my favorite parts of this whole deal is cleaning the aluminum transfer out of good own cylinder’s and saving them as the quality of the aftermarket stuff is absolutely disgusting… for the $ they are asking…it’s nuts… titanikel is just flaking turd fodder!!! It blows compared to an OEM Stihl cylinder lining!!! Keep kicking azz!!!

Isn't this coming weekend the third weekend? Can you train hillbilly dolphins? On a real note, what kinda numbers would you port the Venerable O90 to?

Hello I found a older foredom ee series but can't find any info. But kinda looks like your older one you have hanged. Is yours a ee series?

The 90 degree unit doesn’t pop up, what’s the name on it if ya don’t mind

Can u put some links up to find the tools to buy

Where's the dolphin training channel It's something Passionate about

Where's my saw druggy!!???

I have the off brand 90 degree hand piece to fit my Foredom and it works really good. The Chuck on it sucks imo.. but I got for 40$ off Alibaba and it gets the job done.

Where do you look for these SRs for under 100 bucks?

John, Do the OEM cylinders have a chrome liner or Nikasil? i've been practice porting on aftermarkets and find I get liner chipping with good burs

Dude that sr is expensive like 800 now

Where to buy that SR?

Do you port echo

How do you inquure

500 likes

You should just run that cylinder and see what happens lol that would be funny if it ran good

How many money i need to buy a chainsaw ported by you?

What are the benefits of porting?

First 5 minutes on my fordom my dumbass hung it in my shirt lol

Anyone have a link to them 75 dollar right angle tools from eBay? I can't seem to find them lol
