well I hate to say it but to me it suck's, I tried to look up some knurls last night well first is you gotta pick which ones you want you know usa or import or dorian and that list goes on. then you have to tell em if you want em in sets or just wheels and every time you select an option the thing will try to look up what you have selected. But what really POed me was when I would select .5 wheels and the would try to go back and select .25 width you could not make any changes.
Guess only way to deal with the devil is to call him up and use the spoken language instead of keeping an ethernet wall between him and me.

Their pricey on their stuff, and I have ordered from them but they don't have .5 diameter rolls, not that I can't get by with something a little larger say .625 and cut a recess in the frame so they will open up, but it would be nice to get the full capacity of the tool, not that I do much knurling over half an inch but you never know.
I purchased the bolts that I needed for the locking screws and adjuster this morning then I turned the ends flat and turned the thread off so that the locking screws would not mar the top or end up with mushroomed ends, I also cut a slot in the top of the arms when I made them.

I took another look at mine and the knurls are 5/8" x 1/4". It looks like they cheated a bit on the .625" square stock and made it .635 so the knurls can retract into the slots.
Also, McMaster Carr is actually cheaper than MSC for that size knurl.

The first row shows 1/2" inch dia. rolls. I just clicked on the RH Spiral catalog number (33425A61) and this popped up in the details box:
Right-Hand HSS Circular-Pitch Knurl 1/2" Diameter, 3/16" Face, 3/16" Hole
I made the bar with 1/4 inch slots and 1/4 inch holes so might as well get something that will fit.
Fair enough - from what I read 1/2" dia. seemed to be the critical value. May have been easier to design the tool to accept the knurls available but hindsight is always a wonderful thing
its not that the knurls aren't available, just that MSC's online catalog PO'ed me the other night. all I have to do is call em up and tell em what I want and 39.95 later they are in the mail. but due to bills I have to wait till I get my check in January to order them.
I would of made the slots to of taken 5/8 shanks which would of been easy to of gotten a 3/8 wide roller into, but with all the things that happen with a casting I figured that a half inch deep slot was at the max, which doesn't leave a lot of room for putting pins into a .5 wide shake with a .25 slot in it.
there are several options that are available to me, one I can slot the frame ends and use 1/2 X 5/8 shanks which will allow the wider rollers but then I will have to cut a recess in the frame for the wider diameter roller to fit into so the full 2" opening is available to inserting round stock into.
almost forgot I have three sets of metric rolls that have 5.5MM pin holes in them that are like 14MM in diameter and a bit wider then the 1/4 inch slot now I could make new bars to fit them, but (there is always one) where in Oklahoma do I find metric dowel pins. and for me to make them I'm gonna have to borrow Bob's bright and shiny finish camera, it's one of them
kind of things I'm danged if I do and danged if I don't, but I will get rolls in it that will fit just like the store bought one. cause it had the same .5 rolls in it. anyway the one listed on MSC does, not sure about Tom's
been a while since i last posted and update on the knurler that I made. Anyway I finally got around to ordering some smaller knurls for it and got them installed today, seeing as how they are 1/2 X 3/16 X 3/16 hole I had to make new shanks for them so i cut up a couple more brazed on carbide lathe tools for the shanks. and milled a slot and put in the pin hole.
Anyway heres the photo, pins are too long but due to weather I didn't get out and go get shorter ones but will change them in a day or two, or I may just leave them like they are.
But I may make a larger one with a bigger bore for doing things bigger then what will fit into this one.
