Quick change tool post.

The following pictures and text describe a quick change tool post that is a modification of some tool posts I have seen. The most convenient feature will be the actuating mechanism which is built in and requires no extra tooling.

This is the start of the tool post. The carrier has had it's dovetails cut. The tool post has its dovetails, mounting hole, pusher hole and cam holes drilled/ milled/ bored.

This view shows the tool post from the top. Not the counter bored hole, this is for a stainless steel bushing. There are bushings top and bottom. The tool post is large enough to have a tool at each end.

This picture shows the top bushing and the cam pin in place.

This picture shows the basic, but not all, components. The bottom bush can be seen at the bottom of the picture. The cam pin is made from stainless steel. It doesn't yet have an operator handle as this has to be marked up once the unit is complete.

This is the pusher pad. Note the stainless steel insert. The bushings and this insert have been reamed out. I reamed it to 6.40mm as I had one to hand.

Almost there.

Toolpost in the unlocked position.

In the locked position. I may put a slight bend in that tommy bar.

QCTP and some family members. Three of the carriers need their adjuster screw, all need the adjuster lock.

With the toolholder at height the clamp screws are quite close to the tommy bar so I'll bend the bar up a bit and, if necessary, lower the clamp screws by machining some metal off to make a step then use shorter screws.

The height adjuster is going to be knurled but I've got to make my knurling tool before I can do that.
