Documenting the adventure of making an eg machine base. Mostly photos and some words.
First test pieces were eg added to 4th axis subplate.
Aggregate dryed for week in the sun then vacume dryed for 4hrs per 40kg in a 60L paint pressure pot.
220kg cast so far
10-12% EPoxy by weight
West 105
West slow hardner
Gerneral builders mix (used for diy concrete) + extra crushed ap12 and pumice to get a good grading of aggragates.
Black pigment.
Hand mixed first then
Mixed in 10kg batches in buckets attached to my rotary tumbler. This was one of the best decisions as mixing 10% is hard work. Orbital sander for vibration.
