Coffee In My Sugar: A Scissor Knurler / Lathe Question

[ACHiPo]

Below is a picture of the finished knurler after a trip to the blackening tank. I'll create a write up over in the projects area (I'm trying to get a sub-forum set up). I'll title the project "Marlco Knurler Clone" - in case anyone is interested.

Seeing your nice work reminded me that Hemingway makes a knurler kit:

Looks interesting.

Wow this is begging for a DIY project using a 3 jaw chuck mounted in the tail stock with the 3 jaws modified to hold knurl wheels. Slot the end of the jaw and drill for a hardened pin for the 3 knurl wheels.... Maybe small 3 jaw mounted on a stick to mount in the QCTP even easier...

Very good guess...but not correct.

I will give one more clue that is pretty obscure because I don't want to make it too easy for guys like Mikey and DarkZero and I don't want to hijack the OP's thread. It is part of a larger project that I will post as soon as I can.

Clue: 7,7,30

my shop-made one; it isn't the most powerful of the three but it is the most precise and produces the nicest knurls.

It's also one of the most elegant looking knurling tools I've ever seen....

Thanks, Frank!

I believe what @Cadillac STS meant was a DIY knurler project. That Dorian knurler looks based off a micro chuck like Sherlines & Taigs use except the Dorian knurler appears to have dovetails for the "jaws".

Well, anybody who's anybody knows that this is the DIN spec for a camlock spindle taper - 7 degrees, 7 minutes, 30 seconds. BUT what we don't know is what that has to do with a knurled O-1 round thingy unless you are making a D1-4 rectal torture device! Say it ain't so or give us more clues ...

I to have no idea why a spindle nose taper would have a knurled handle on it? A gauge for checking/bluing backplates? I dunno but I think it may be a fancy machinist's torch. Gonna mount a chuck to it to hold a flaming torch to run in a marathon or be in a parade.

At over a $1000/ea. for Dorians, I do believe 'Hobby' & 'Budget' have been kicked to the curb.....

Mike is a SERIOUS hobbyist!
