Steel or Aluminum,that is my Question

We actually have a huge bonfire ready to burn in the back yard as soon as the weather cools down,
I would much rather put the money into better ball screws and running gear then pay to ship the frame all over the country side.

Hi Spud

The link below is a PowerPoint presentation a while back, It details how I made an epoxy bearing material using epoxy, metal powder and some low friction materials. Teflon, molybdenum disulfide, and graphite, these three elements are not needed for an epoxy grout. You can make a thick paste from epoxy and iron powder alone that will make an excellent high strength grout for filling the small voids left between machine members.
As you live in Australia the sources at the end of the PowerPoint are relevant.

The link below is to a great build done some time ago. The post clearly explains how the builder used epoxy to grout joints before bolting.

Hope this helps
