Not sure about the process of filling a machine frame but generally speaking adding something like 403 or 404 fillers will aid. You can find a list of fillers & uses here. I generally use the 403 but that's more specific to work I do & not filling a machine frame.
Is it really necessary to start filling your frame with resin?! How much of a difference in finish are we talking for the extra expense and hassle?! My gantry will be ali extrusion in the L configuration btw... I don't want a terrible finish on my work at the end of all this but at the same time I'm not going to be machining parts for Breitling!
