Building a milling machine
NormanV:
I mentioned in an earlier post that I intend to fill the body of this machine to reduce vibration. I could use concrete which would be cheap or a mixture of epoxy and gravel. My concerns over using concrete are shrinkage and retention of moisture. Epoxy will be much more expensive, or how about polyester resin (as used for fibreglass).
Has anybody any experience of doing this who could offer advice?
Thanks, Norman
chipenter:
If you used strong concrete and vibrated it to remove air bubbles , it will be waterproof and ridgid not to menshon heavy .
NormanV:
What do you mean by strong concrete?
Arbalist:
Polyester Resin should be fine I would have thought, mixed with sand and gravel.
awemawson:
If you can get some chilled iron shot, as used for sand blasting, it will be significantly more dense than aggregate. And I agree that polyester resin should be fine.
