Denford Triac Mill

End nut style suggests that it could be a Clarkson or similar type holder for screws shank end mills.

The chuck you are holding is a Clarkson and the collets available in inch and metric sizes are for screwed shank cutters. Guessing size is for 6mm to 16mm collet range (6,8,10,12,16) or inch equivalent. Metric collets have a groove cut into the threaded head. Clarkson chucks provide a very secure method of holding the cutter, some may say the best.

The other tooling pictured is ISO type shanks but you said the spindle is R8 so will be surplus.

You seem to have a good array of Easychange chucks, at least enough to get started.
Collets pictured are DA type which makes me think your Easychange collet chucks could be for DA collets.

ER type collets are more universal as they have a gripping range of 1mm diameter.
I wouldn't bother with making tooling to suit Tormach holders if you have ER Easychange holders, you only need a few toolholders to allow multi toolchanges during a program.

I use easychange on my Bridgeport clone and have had no trouble at all. Mine has an allen screw that you can tighten if you are doing heavy cutting but I doubt you will be able to over work it with the Triac. It looks like you have a good selection of holders, So even if you decide it isn't for you, I'm sure it would make a handsome price on ebay (possibly enough to cover the refit. Personally I would keep it.

Regards.

Hi Mark

How are you getting on with the Triac, cutting chips yet ?
