Epoxy leveling is a waste of money and time, unless your trying to correct defects in the frame build levels. Your machine levels will move even if it's bolted to your workshop floor and the levels you had yesterday are different today and will be different again tomorrow !

WHY because the ground your workshop is built on is moving very slightly up and down all the time, water levels (hydrogeology) cause the ground to swell and shrink several times per day, the temperature inside and out will contact and expand all materials very slightly so what was once level may never be level ever again.

So unless you need to correct any flaws with frame build levels don't waste your money. Buy yourself a beer and sit and watch the room moving or was that the beer that caused it to move.

All the best to everyone for 2015
