I took your comment to heart but here is a commercial grade tool (Same brand that Nick has) that does not cut with the leading edge: https://www.youtube.com/watch?v=46mPFZrVAKk at 1:30 in they cut-knurl with similar configuration to what Bazmak et al started with. Nick, can you confirm if...

At a list price of over $1200 your comment is more or less irrelevant in this present context? (Nick I initially misinterpreted your comment and realized later that there is a wink at the end, sorry for sounding snarky.) If the work you need to do is within the range of .5-1.5", what reason is...

The Dorian style does not have adjustable pivots, the AccuTrak, Hardinge and Zeus ones do. The article you mention is in essence a Zeus clone. Personally for hobby use I find that version excessively complex. The Hardinge style is much simpler and just as effective (to quote a good friend of...

The first 20 pages to the Dorian catalog has a wealth of information on knurling, this would apply to both cut and crush knurling. Covers diameter of work, SFM ranges, depth calculations etc.

Except that Dorian does not adjust the angle of the cut wheels for the range of .5 to 1.5". Indeed the way Bazmak, Kerrin and I built our versions we are not cut knurling in the usual sense. But is is an approximation that produces ok knurls. I had a very close look at page H28 of their...

USD600-900 for the Dorian. Never going to happen here :-) But, much can be gleaned from their catalog.

I'm still learning about depth of cut and feed rate so perhaps there will be improvement. Although I don't expect commercial quality, I can at least produce 'acceptable to me' knurls for the first time :-) I agree on the lack of adjustment being a potential problem beyond some diameter range...

If I had a larger 60° dovetail cutter then it would have been direct mount for me as well. But didn't want to put the project on the shelf while waiting for a cutter to arrive.

And we are done. I am calling this a success although I still need to read up on depth of cut on some of the commercial vendor sites. I will be cleaning up the sharp edges and blackening the tool etc. but very happy with the results. The 30° angle results in almost square knurls. I used manual...

Progress so far. I decided to mount the knurl carrier at an angle onto the mounting block so that I don't have to rotate my QCTP for knurling. Still have to make some brass bushings and trim the face of the carrier to clear work piece. The mounting block will get milled down to fit an AXA tool...

A beautifully simple implementation. Thank you!. I will adapt to my .75" diameter knurls and post my results in a week or two. Gerrit

One bit of organization that might help is to collect the bits and pieces for a particular project and put them into a plastic shoe-sized box. We have them 'over here' in the colonies at HomeDepot. Cost is maybe $2 Canadian. My wife has been using them for her knitting projects and I am now...

Making the big list is great but at some practical stage it needs to be prioritized and then refined. Like iterative design. Otherwise it becomes too daunting a task to complete the whole list. My approach has been somewhat similar, where I have 3 machines, each of which need additional...

There is http://hobbymetalskits.com in US. They have Class 40 ci. For willynfo's brother that would work if he gets a US post box, eg. at http://cbiusa.com There is also http://www.alro.com/divmetalsplus/ in Tonawanda, NY which has a retail location for cut-to-size.

You can try contacting the authorised foundry in Quebec? http://meehanitemetal.com/our-foundries/ Gerrit

It is still published by Tee Publishing for GBP19.95. I just bought a used copy for US$1.00 from AbeBooks as gear making is in my future I think. And I get the previous owner's notes for free :-) Thank you for posting this.

So the modern UK banking system won't let you have an EU account at your local branch?? We have a USD account at our local credit union. Once in a while we transfer CAD to USD into that account. Yes there are fees incurred but we try to do this when the exchange rate doesn't totally s..k. We...

It is simply exchange rate fluctuation, the lister is in Germany. Happens all the time over here, US listing translates to Canadian $, fluctuates all the time. You should have a Euro account and only source from the original listing.

Except when you try using a very small centre drill and your tailstock/headstock is misaligned. Snap goes the tip. Sherline made their tailstock chuck adapter adjustable for a reason. As an expert watchmaker on another forum indicated, for machining Taig, Sherline and the like you need to...

I have turned 3.5" on my Taig, not something I would like to saw off with a hacksaw, steel or aluminum :-) It is easy to underestimate what can be done on Taig, Unimat etc. Just look at some of Rudy Kohoupt's work. They are small but very capable. Gerrit
