It wasn't luck that got you such a good result, it was skill!

Was awesome dialing in that stock on the 4 jaw by eye!!

I have been machining for many years and have worked at a number of shops over the years, I have never heard of anyone running the cut backwards for chip control on brass! What an amazing idea thank you! This shows you are never too old to learn, I am 69

Ive not done any turning with the tool up side down. But seeing this, im going to have a go at it. cheers Max.

Always enjoy your Etch-a-Sketch technique 👍

I don’t worry too much about knerls. What happens is that once the cutting actually starts, the knerls sync up pretty well. That generally happens because they push the metal around the piece by a tiny amount and as the knerls are free wheeling, their speed changes to match the cuts, not the rotational speed or diameter. I know that sounds odd, but I can’t explain it any better without showing some graphic illustration, preferably over a timeline. But it does work. It’s why knerling is possible at all. Otherwise we’d need knerls for every single diameter. Instead, we have knerls for different size cuts instead. Generally though, as is obvious, smaller diameters usually have smaller knerls. I just recently used a straight knerl of 30 teeth per inch on a small stainless knob I made of 0.875 inch in diameter. In theory, that shouldn’t work, but it did, very well.

G'day Max. The duplicating jig does a really nice. Well done with the Max Touch. Lol😅😊

That turned out well Max. You've got your CNC arms working well. I had to laugh when you had the spindle going in the wrong direction. I'm currently machining a batch of 44 parts in my HBM and there is one threaded hole in each one. This is the first time I have done alot of threading in my HBM. I reverse the spindle to back the tap out and then the next step is to centre drill the next part. The number of times I have tried to centre drill with the spindle going the wrong way is embarrassingly high. Ken

Great job Max, love the "Manual " tracer jobbe 👌. Thanks for sharing

That "manual tracer" is super cool. Might have to make one of those for myself. Side note, your hand profiling skills are superb. I hope that people appreciate how difficult it is to do that.

I am definately making that profile tracing fixture. I will mention your channel when I do - if you don't mind. Looks like the same lathe as mine. Great job Max.

Nice build… great free hand

Max, you gave many ideas with this video.......thank you so much, ....Paul

Turned out good max. You gets all the handy ones 😂

Nice work very interesting

Another 'Tractor' part nicely replicated ;)

What a coincidence that I plan tomake the knob for the Belt tracking today. You made me changed my mind from aluminum to bronze. I don't have a big selection but I found a piece. Thanks Max

Ta MAXI Mollydooker excelent vid mate love the close up cam shots cheers youve earnt a Beer or 10

thanks for the videos Max you're a bloody legend!

Thanks for the looksee!Nice.

Thanks for another great vid.

Max - It looks better than the original . -- Jim

The father of one of my mates reckoned that BSF was a bloody silly fred

Nice knobs Max mate! That tracer setup is crazy, simple and effective, great job as always

That chunk of brass must be worth a fair old whack these days. Metal prices are going crazy at present. Nice detailed work Max.

Nice job on the knob! I bought a hydraulic duplicator 10 years ago for $30 - old obsolete technology in industry. Made some missing parts, $100 of new oil and new electrical cord and it does what you just demonstrated with a little less skilled operator - me😂

Thank you Max!

Spot on! 👍

Good stuff Max. The bit on the knurling I did not know, always wondered why the diameter was important. The templet tool I have seen one before, as my Dad would make cabinets and other furniture as a hobby. Cheers

very good job friend Max,,thanks for your time

something i have never thought of,,,,making your own brass door knobs!!!👍👍👍

Max, Love your simple manual tracer setup. I’m going to have to make one for my lathe. Cheers, Will

Yeah nicely done. Good practice to get it to match so perfectly. Likely unnecessary but its good habit. For those that want one of those radius templates, bunnings sell them. Empire brand. Very handy for lots of things.

WOW you have quite the touch on the lathe Max!!!! The template gauge can be gotten at woodworking supply stores. They are available in plastic fingers but I prefer the ones like yours with metal ones. Cheers

Great job mate

hello Max, looking great my friend, Paul in Florida in the US.....

Awesome fine work. Pretty tricky to get those curves just right. .

Wow just wow, As iv said before, only to be able to stand and watch a master craftsman at work, Thanks Max for sharing your wealth of knowledge and experience with us, From kiwi land

Thanks for sharing 👍

Thx for the vid.

Good idea to put the tool upside down and run the lathe in reverse. So you don't take a chips shower. And the free hand forming is something I need to practice more. One day maybe...

Freeform cutting a profile like that can be risky business but you make it look like child's play. Nice job Max. I really enjoy your videos!

Nice work , great skills Max Cheers Chris

13:00, I learned some great stuff about knurling and diameters, thanks Max

A work of art Max, very enjoyable to watch. 👍👍👍

You can grip short work in ER collets if you use a section of stock turned to the same diameter to fill up the back section of the collet.

Good afternoon Max. Art turning I call this.👍

Nice win. Thanks for all the tips - cheers 🍻

Very nice idee for the copie setup, i am convinced you run a Segwai lathe, bigger than mine but very simmelar parts and the handwheel at the right side, safe for swarfs.

Hi Max, lovely knob you got there😂, something to consider is the wood turning method work on brass lovely, just where got remove bit especially on a rad like your knob , just found 2 temco on UK ebay as well. Steve

Hi Max, radius versus direct, catches me out on my DRO when i forget to switch back. A lot more copper compared to zinc in the original knob. Copying the engraving might be challenging for the owner.

Hello Max, watching you bang on the chuck key made my hands hurt... I know you have been at it for eons and eons, but those delicate tools of yours we call hands are paying the price.....I recently took some 25.4 mm tubing and made a handle for my chuck key, I just welded to the key of one that would not keep the handle in....what a difference it made in comfort, I also made it about 50% longer....I only have a 13" old South Bend, but the amount of effort and Pain I no longer get is amazing.....it makes 4 jaw work much nicer. too....hope someone can appreciate.....cheers, Paul

Hi Max. Nice work as always. I have a set of Acetal pads for my steady rest when galling might be an issue, works really well. If anyone has trouble finding one of those profile gauge, you can get a tile profile gauge from most hardware stores they are generally plastic, but do a decent job. You mentioned being lucky on the profile 2nd side, I think it was Jack Nicklaus who said "the more I practice, the luckier I get", wise words from the master. Best wishes, Mal.

Max an old trick that I'm sure you are aware of Is to oil the back side of emery cloth and wrap the back side around the stock. Then snug the non-roller tips to the abrasive side of the emery cloth. This allows the material to rotate inside the emery cloth without marking the stock. It's an old gunsmith trick. Excellent job you are doing without my advice so thanks for bringing us along.

Well done Max, I really like manual tracer setup.. Knob job turned out great 👍👍 Cheers....ATB...

Max have you ever tried a roll of emery cloth around the material. You put the rough side facing the fingers and coat it with oil. The paper stays put and prevents wear but keeps a loose tolerance.

You know Max I love a clean chucking surface, I've seen so many with chip gouges in them , it's one of my peeves!

Nice job? Shit 10 Fahrenheit and wind here this AM in the north east US. Keep up the interesting projects!

Great stuff Max. Have you tried a graver ? Great for freehand profiling . Got a bit of s shock buying material 60 mm fia x 300 bronze dolid $287. Ouch .keep up yhe good work

Nice work Max! The only difference I can see is the depth of the straight knurling. Maybe put a threading tool on it's side and divide by the number needed and cut the grooves by light shaping?. I can index on my lathe spindle which is ideal for cutting small patterns like that. But it's probably overkill for this part. How about the engraving on the top? Do you need to replicate that as well? Thank you for sharing your work. It's a joy to watch and I learned about manual tracing a part for a future job! Thank you Max. Best, Job

Always nice work with great explanations.

thats a nice copy max. i wonder how close you can copy if you use a dial indicator and hold it at zero instead of a stylus? cheers ben.

Hello love Your work ! Why do you turn this bress upside down ? doesn't it lift the front of the carnage ? Thanks Alec

Didn't you have one of those turnado things? I thought you reviewed it once. If not they are pretty cool for tracing. Maybe you can hit them up and score one to review. I'm not affiliated, they just look fun is all.

Cheers Max nice job mate ,as you say if you havent made any cockups you havent done machining very long👍👍👍

? ... so having the cutting tool upside down and the lathe running backwards = does the 'Knob' end up being Left or Right Hand ?

Great video, but that is one expensive brass knob, with the price of brass bar that diamiter, cheaper to buy new set of knobs. ,

👍

Hi Max, have you ever tried a cut knurling tool ? No pressure problems as with pressure knurling. I use one with my lathe which is similar to yours, and it would have cut that knurl without moving the workpiece.

Rollers on the steady rest, but actual rollers not just bearings running on a stub, or some nylon running pads instead of the bronze pads.

You have had the profile gauge a while!

Max do you have a air compresure

BSF, Top Brass Max. Love the tip. Running in reverse. Point this n Point that? I thought I was a memory dumbo lol. I am well behind you Max. Cheers Tony

Upside down tool I thought all the tools in Australia worked upside down.....

At 25:25 "19 mm, what are we at , 18.7 mm; 1.3 mm". ???? No .3 mm There is your error. 🙂

Now Max you do realize the double tracking is purely an expression of the diameter of your stock vs the diameter of your knurler. So as you apply more pressure your stock diameter will vary and the knurl will effectively come in and out of focus. So all the pre-examination is rather useless. You just gotta dial it in until they look crisp. Nice end result though for what it's worth.😊

The order of operations was off. The knurling should have been done right after the two (front and back) profiles were slightly cut. The knurls then would not have had such an abrupt beginning and end and would have looked more like the original. Great innovated job otherwise.

So who worked for Porirua Engineering in New Zealand? Or was it the Aussies stealing again 🤣

Minge over?? i hope no Glaswegians are watching
