NickG:
You can buy 5" square here: http://www.m-machine-metals.co.uk/Catalogue_doc_MAY_2008.pdf but does it really need to be that big?

One of the reasons I come up with

Was I did not have or could easily obtain  a block 4 inch /100mm cube.
I have since used the tool post to dress a 12 inch/300mm block of cast interrupted cut taking of a kilo of swarf.
That is without the webs added.

AdeV:
Phil & Trev - I love both of your designs; I don't think I could do the welded one, though, my welding just isn't up to the job. Sure, I could get the welders to do it, but then I'm spending £££ again, and this is supposed to be a low cost solution  :lol:

Nick: I did wonder about whether it had to be 5"x5"; that's just the size of the current holder. I'm wondering if I'll ever use, or need to use, 2" sq tool steel (which is the capacity of the current holder), or whether 1" sq will plenty. In which case, I could go a bit smaller with the tool holder. Then again, if I can get the metal at the right price, I may as well "go large" for the extra rigidity I'll get.

ozzie46:


  I may be wrong here but I think the large mass to the tool block is for vibration dampening more than anything else. At least on the smaller lathes.
Just my 2 Cents.
