Thor, or should that be Zeus?

Mounted the tooling alu, a quick sweep tells me it looks to be accurate to within 0.05mm. Not ideal but not bad for a garage job.

Around 6 coats of carnuba wax later, we are ready to pour the epoxy.

The epoxy takes 24-48 hours to set but will leave it for the week and remove the reference table / plates to see the result. Then it will be a case of drilling holes and mounting the rails which is a pain in the backside. Not sure yet how Im going to epoxy the nuts in yet - when doing it from the top, gravity helps. On its side, not sure.

Success!

Apart from some places that remained a bit unmixed, the rest has gone hard and is mirror smooth.

Removed the reference frame, alu still 'stuck' to the epoxy.

Then, a bit of prying with a crowbar and both parts are off.

The remaining epoxy is smooth and even has the tooling marks that transfers across from the plate.

A quick test with a straight edge confirms all is good. A quick test with the rails indicate they arent perfectly straight (This will be fixed as they get bolted down).

Next step is to drill two holes, around 1/3 from each side and mount, get basic alignment, using reference piece for X travel height calibration. Marking the rest of the holes, drilling, then mounting with another alignment test. This takes ages as I need to go to around 26mm from memory and there are many to drill into this hard concrete.

Not sure if anyone is actually reading this thread anymore or not.

Im going to use a cheap chinese spindle (4KW) to start with. Ill look at a more expensive setup later.

Good source for decent quality ER20 collets please?

Thanks
