Looking for a 3/16" x 1" woodruff slot cutter
I need a 3/16" x 1" woodruff slot cutter for a one off job, after which it will never be used again. I'm shocked at the prices of the local P&N woodruff cutters ($100 +) and CTC etc aren't into woodruff cutters.
I can get away with a 3/4" or 7/8" diameter cutter, or I can make 2 cuts with a 4mm wide metric cutter.
Any thoughts on sources?

Are you wanting to cut a "T" slot ?
If so then I would mill a slot of the right width and fly cut each half.Best Regards:

I tend to avoid woodruff keys like the plaque.... Industry likes them because I assume they are quicker and cheaper to make.. Compared to a featherway key..
In making replacement parts I just replace woodruff keys with featherway keysLight red, the colour of choice for the discerning man.

A very vague "I might have one" has turned into a " how about that - I do have one"
Send me a PM if you want to borrow it.

Thanks for the loan offers guys, but I'd really rather buy and use my own woodruff cutter.
Reason being that when I stuff up the loaner I need to buy a replacement anyway.
That said, I think RC has the right answer, there are alternatives. While a woodruff key is kosher for what I'm working on, I can get by with milling a slot in the shaft and using a conventional key.
For the one or two of you that like me know little about woodruff cutters, while I was roaming US ebay I noticed that a lot of the cutters on there are only described by a 3 or 4 digit number rather than thickness x diameter. Turns out that the last 2 digits are the cutter diameter in 1/8"s and the first one or two digits are the cutter thickness in 1/32"s. eg a 1011 cutter is 5/16" x 1 3/8" a 608 cutter is 3/16" x 1" etc. A little more arcane knowledge.

Hi Bob,
There isn't a name for such key but if I had to call it something I would say it is an 'inverted peg feather'
Although a few other descriptions have sprung to mind but not printable.

I suppose it is another version of a stepped key. What I know as a stepped key is a T section key which is quite common in the old Chevrolet world, among others, where it is often necessary to fit a back hub with a 2" long by 1/4" wide keyway to an axle which has been remachined with a 5/16 or 3/8 wide keyway because the original keyway has been flogged out beyond reasonable re-use. I imagine it was cheaper to do that than to replace the whole axle.
Frank.
