Thats an odd duck

Yep, You are showin' your age Kath. Gave me a headache to see them after all these years but I once cut cavities for low pressure molds ( gravity fed ) on a Tree dual rotary that used these things. Parabolic lens Injection molds as well. Great machine and if your math was good you were golden.

Thanks Kathy.

How were they held in? Ive been around a lot of old machines in the last few years, but never saw these before.

I've only ever seen them on a manual vertical milling machine. I seem to recall a special spanner-type wrench that you used to tighten or loosen the cam-lock thingie that rides a couple of pins in those slots

Those holders are called Rapidaptor made by Kingman White. They fit a master holder available with many shanks like R8, 30mm,40mm, MT etc. Push a detent button and give a quarter twist and they are out of the spindle.

That's it! I knew I remembered using these a few years ago, we had them on a Tree miller I ran occasionally.

These holders are for the famous "RAPIDAPTER" - for Rapid adapter I suppose. The device is still available but I don't think they are manufactured by the original company. The device fits in the machine spindle and has a large knurled ring around the outside that , when rotated, is locked in the open position by a large ball detent that protrudes through a hole in the knurled ring. The holder is shoved up into the tapered I.D. of the adapter aligning the slot in the holder with the locking bolt in the adapter. The ball detent is then depressed and the holder is held solidly when the locking bolt rotates into position under spring tension.

Hi Gunner..

I took a look at these holders. I'm puzzled. I don't know what they fit; but Why do they look as though the camlock feature is built backwards for a right hand end mill ?

It looks like if you turned the power and started cutting the holder would release. I must be seeing this backwards.

Please let me know what YOU see. *Smile

Happy mother's day. *g

Ah--Ha! That's why the cam lock looks like it's made backwards. It's held by an external ring.

Whew! I thought I was seeing things.

Thanks,

Stan-

Hmm ... looks like it would not take kindly to a left-hand end mill. Were there some with the cam slots reversed?

Enjoy, DoN.
