Jonothan for me its easier to mould something that is all and its what im used to working with, i have the skills to mould things and this means i can do stuff at home very easily rather than pay for it machining or casting ,its as easy to mould and epoxy into place as it is to machine metal to thousandths, I suppose it depends on your background I know we have had cast bases supplied before and its purely position and glue that gets the tolerances
That was my worry they are being tight on the resin volume.Jonothan did you gleen anything on the start point for sizes you could quickly post up I have read that many combinations on there?
I do know the companies that pour this its done with technology (equipment) not dissimilar to laying concrete foundations I have seen it done and it is a lot wetter than anything aproaching the 10 percent figures I have seen touted towards the end of the thread, The rails (precision rails) were mounted on grout which was similar to moglice but with ceramic spheres in it and it did indeed look like grout till it glossed over,this glossing seems to indicate far more resin richness as the heavy particulates sink
Im assuming its coming down to a scaling factor some of the aggregates they put in the grinding bases of the carbon machines we design are up to 25 odd mm I'm thinking the smaller the machine base you scale accordingly with a wall shickness ratio
I might just have a go this weekendLast edited by mike mcdermid; 20-08-2012 at 08:35 PM.
