think its repairable?? iv got some jb weld :lol:
been thinking things over and have decided to go with the flat plate for now, as its simpler and I reckon it will be strong enough. the loss of height isn't really an issue ( I think) and will certainly make changing belts easier!
plus if I do eventually go with a 4'' riser block, the head will end up back at its original height

Funny you should say that! Have you got all the bits and are they big pieces?
The base on my Aciera mill must have been dropped and badly broken before I acquired it. It's held together with something like JB Weld and steel brackets and plates on the inside - you wouldn't know from the outside. I must have had it for for nearly 30 years and it's still going strong.

Swarfing:
If yo got all the pieces for the base, stick it back together and use it as either a plug to cast a new one out of ali with thicker walls? or use it to cast a a thick walled plug you can then bond inside the iron base with some epoxy resin. Keeps it original looking and very strong?
vtsteam:
Along the lines of what these guys are suggesting, stick it together with JB Weld, screw some straps under across the cracks with countersunk screws from the top, leave them long, then invert and fill with concrete. The screws will help bond the concrete in, though it would probably be sufficient without. It'll be heavy but, that's a plus other than for moving it. A cross of 1/2" rebar, corner to corner set in the concrete wouldn't hurt either. Fill any bad spots from above, sand and paint.
bertie_bassett:
Hmm I hadn't thought about filling it with concrete. Not a bad idea.
Its in three big sections, though I'm missing a bit.. Will pop back to where I got it and see if its still there.
I did also consider sticking it together ontop of the plate and then building a support under the main column
More things to think about.
