Hi Tyler,

I started to make your MT3 die holder for my lathe. Since it is MT2 and I was trying to use material I had on hand, I changed some of your dimensions. I also made it for a 1" hex die.

Then I stumbled across information that would make it more flexible.

I found Neil Butterfields site-http://nbutterfield.com/d.aspx.

So I started incorporated his ideas to your design with things that I had on hand.

I got his permission to post my variation, so long as I gave him credit for his work.

If you are interested, I will post pictures.

Thanks for all of the help.

I need to take better photos. But at least I got something up.

Top piece is MT2 die holder shaft. MT2 on one side and the rest is 3/4" by 4". It is drilled out  to 5/8th" by 4" deep. This was my first attempt at cutting an MT2 taper and it was an interesting experience. More on that another day.Lol.

Left piece is die holder body and sleeve. One side you see the 3/4" Id and the other side is the imbedded part of a 1" 6 point impact socket. It was put in with both interference fit and locktite.

Next two pieces are both a 1" and 13/16th" die holders.

Last on right is the driver for the tap holder collets. It will hold that in place with both a set screw and a driver i put into it. The driver is 1/2" by 3/4" long. I cross drilled it and cut a slot into the drilled hole. My tap holder collets have a spring pin in them that the slot goes through. In the ENCO catalog they call them adapter on the Hand Tapper-http://www.use-enco.com/CGI/IN…..M=893-1274  .

My adapters  goes from 0 to 5/16th taps and is a little different.

I also made a Tommy Bar since I took the photos and drilled, counterbored and tapped the die holder/sleeve for the TB. .

I will try to get better photos soon.

Again thanks to Tyler and Neil Butterfield for posting the drawings and information.

Tyler,

I don't think that it will slip. I think that I gave the wrong info on my original post. Thinking about it, I believe that I used epoxy to hold it in rather than locktite. I seem to remember that my shop had hidden the locktite and I used plan B, slow set epoxy. I cut some slots in it before prssing it in, for extra epoxy to go into.

I forgot to mention that I also drilled through the sleeve and socket, then I tapped both sides for 8-32 for set screws that will help hold socket and die in place.

I might make more tap holders that copy what Neil is using now.

Thanks,

Fred
