Impressive kit and loads of space.

I believe this type of knurling tool was originally a Marlco product. It's very good up to a point in relieving the pressure put upon the work and lathe spindle by a tool-post mounted knurling tool but there is a flaw in the design. I made the 'standard' size version when it was described some years ago in a model engineering publication and also a double sized one to knurl the large index ring on a Quorn I was making (still yet another unfinished symphony!). This was a little less successful as the knurls tended to wander a little due to the increased flexing in the elongated arm. The problem, in my experience, lies in the eccentric at the rear of the upper arm as when the lever is operated to increase the pressure on the knurls the top arm is moved slightly which tends to destroy any nice pattern generated when the knurls are rolling in 'synchronism'. Other than that, providing you bear this issue in mind, some nice results can be achieved when the knurl pattern emerges and no further adjustment is made.

Thanks for the info

That's an excellent piece of work, Celso Ari; well done. It is always interesting to see how other people make things!

Is there another video of it actually working on your lathe?

I'm really pleased you posted this, I had not come across your channel but have now subscribed -some very interesting videos I'm looking forward to watching

Very nice job. Could be really useful. I bet they did not cost the average $8000 that Adaptix charge for theirs.
