I am building the hemingway straddle knurling tool. I have to make a decision on what size knurling wheels to use before I cut metal. It is designed for 1/2" dia x 3/16" wide x 1/4" hole dia. knurls. Can anyone ecommend a source for reasonable quakity knurls this size? Accutrak makes nice ones but they are $31us each. I'm sure if I was doing production work they would be worth it but I'm not. Any suggestions welcome.

The ones you can get from Hemingway are quality wheels.

Rephrase the question, "I want a useful tool that costs virtually nothing"
In this quest your best bet will be alibaba.com, you may be able to score several knurling wheels for less then a ground shattering $31.00.

If this does not work contact me and I will give you a handful of the most common sized wheels, 3/4" D X 3/8" W X 1/4" D bore.
Specify the pitch and angle.

I suggest you contact Form Roll Die Corp. They sell small knurls for fair prices and will bevel the edges of their knurls to facilitate axial running. They make good quality stuff.

ddicky do you know where they source them from? They only offer 2 pitches - one straight and one diamond. I would likely want the option of getting others if I knew the supplier. I have looked at Roll Die Corp, interestingly they are in the same small town as accu-trak used to be (I'm sure there is a story there) but they don't have the size of knurls that the tool is designed for. But if I decide to go that route I can change the design. Their prices are fair. Still reviewing options.

I have built the Hemmingway an bought all the knurls I wanted from them. High quality and fair price. The knurls are square shoulder not radius edge.

I made the sensitive knurling tool. Same size wheels I think. They are made in Britain good quality. I wanted some coarse wheels and I could not find them. An odd width. I ended up making another knurler with convex type wheels, really nice. Can't remember where I bought them but are US made.

Hey Dave, I have an Eagle Rock knurler that uses 3/4" OD X 3/8" W X 1/4" hole knurls. I could use a pair of convex Accu-Trak knurls, circular pitch, in both straight and diamond patterns. If you have some, let me know and we can maybe see if you want to get rid of them?

These are the Accutrac set from MSC . I have the original packaging that one of my loving dogs tore to shreds …….but I still love them . And here are a few examples of shop made scissor type tools . :) Mikey , I'm absolutely SURE I have a few sets . :grin: The small one is for smaller wheels I used on Hardinges . The other , I machined out of hardened Almar . Quite a lot of intricate machining involved . I sold my Eagle Rocks either on here or Ebay , can't remember where , but like I said , I don't need the stuff any longer . :) Edit , the set is 8s , 10s, 12s and 14s .

Oh yeah? I've been grabbing NOS off of the 'Bay for my Kant-Twist knurler...
Might you have anything with a .25" I.D.?

Here's a cool piece ! I always wanted to incorporate the swiveling option as this has into a scissor type vs. a limited diameter . Someone could sell a handful of them if they had the time to do it ! Anyways , this tool allows you to rotate the wheels for your straight , and any angular pitch knurls . Pretty cool tool . :)
