Removing a toolpost

My Holbrook C10 has a 4-way toolpost that the manual calls a "turret" but I want to replace it with the Multifix that I acquired from eBay some time ago. The problem is that I can't get the toolpost gubbins off the compound slide! I've removed the toolholder block, the 4 screws that hold the ramped base onto the compound slide and the 2 other screws through the bottom of the compound slide into the toolpost base. But the *&^&damn thing won't budge.

I assume these are standard toolposts that fit into a circular hole - what's the secret to getting them off? (I'll ask in the Holbrook group too, but this one seems more active)

Hi Dave,

Some lathes have a circular mount with a dovetail section. Look for a couple of screws one in each side of the topslide which may release the toolpost.

A good idea but unfortunately there aren't any screws on the sides. Underneath the slide there's a circular recess beneath the post, in this recesss is a metal plate, 2 screws go up through this and into the post BUT it looks as if the plate is held in place by 2 screws coming down through the slide and into the plate! Does that make sense? Heat and hammers are coming to mind but I don't want to damage the slide. Another idea is to try to drill/tap the centre of the metal plate and to screw-in a bolt in the hope that it presses-out the post - but I'm not optimistic.

Just as a thought, if I were to borrow the oven for a few hours which will expand more, cast iron slide or MS toolpost?

According to

expansion of steel is less than that of cast iron.

So using swmbo's oven could be a worthwhile experiment

Good Luck
