CVA Rear Tool Post

Mar 27, 2007 32 Replies

I would like a rear tool post for my CVA. The parts book illustrates one but does not give enough detail. Has any one out there got one to spare??!!. Failing that any drawings or photties that would help me make one. There appears to be a double wedge arrangement for altering the tool height.



I have a rear toolpost on mine, but there's nothing fancy about it. I've no idea whether it's original. I'll gladly send a pic if you wish.

Yes please Tim, the bit that interests me is the way the bottom end is attached /located on the dovetail on the rear of the cross slide.

As well as the tool height adjustment.

That's the bit which isn't fancy. Just old-fashioned packing.

Hi Tim / Andy

I have been thinking of making one for my CVA too to carry a parting off tool, if you have any details I would be most interested - thanks

Ian

I'll try to get a pic up tonight. I promise you, it's not exciting

Tim

Ta Tim. You'd be amazed what exicites me. Andy

Prepare to be amazed

TheTeenut which sits in the base block projects above the tee slot, and the toopost itself has a shallow slot which locates on this projecting part, giving two index postions. The third face of the toolpost has to run parallel with the lathe bed, so must be for holding boring bars.

Tim , thanks, Ooooer, I am suitably amazed. I t certainly does not look like the one in the CVA book. Does it really rely on the flexing of the block to grip on the cross slide dovetail>. Andy

The little toolpost also fits the compound. Any chance of some good photos of your TT attachment. I might have a go at making one...

So you have one the same? If so it must be a CVA original.

These were done while I had it stripped down for maintenance.

Yes. Amazing, isn't it

The Monarch 10EE attachment is made to the same design. Look at:-

where there are some drawings. Quite a major project to make one of those from scratch!

Cheers Tim

Thanks for the info, I now need to scrounge around in the lumps of steel department for the basis of the plot. Presumably the thing bears on the cross slide base rather than the dove tail protrusion, if you see what I mean. I also presume that the dovetail is a pretty close sliding fit to start with?

I must say my CVA is an absolute pleasure to operate. The only really odd feature is the M.J.Mouse method of removing backlash on the cross slide screw, still it does work but I can't help but feel that it accelerates wear. thanks again, Andy

Yes and yes.

Agree there, one of mine is really beyond the point where adjustment does anything, time for a new nut is approaching when I've nothing better to do. Having said that, I use the other CVA much more now that it has a single phase inverter drive. Magic.

Cheers Tim

Please stop talking them up - it won't help me find one at a reasonable price will it.

Charles, I have meeting of Toolaholics Anonymous coming up if you are ready to 'come out' and admit your addiction. We are a self help group meeting and discussing not only the problem afflicting ourselves but also how we affect our families and freinds.
