It was an odd reply...
I'm assembling my Ft-5 kit, order 15318, and runnig into some problems with some of the melemine parts....they are falling apart.
The frame supports seem fine, the bolts tightened down with no issues. Now I'm onto the gantry and some of the parts are like mush....the bolts just sink in, I added washes and the washers sink in, no hint of cracking noise they just sink in without ever being remotely tight. FT11 crumbled while I was fitting it to H part with no bolts at all.
Is this normal? ...its like there is no glue in the melemine, just paper???
I can make new parts out of something else easily enough but I wanted to build this stock as I also got hold of a beta CNC kit and figured the feedback wouldn't be very useful if I go re-engineering everything before installing it.
"Melamine is not the most structurally sound material in the world, but if you can make new parts then that would probably be recommended. I think the issue stemmed from a laser cutter error we had recently."
That doesn't give me much confidence. They may have looked at the pics and figured I'd smash any replacements they sent, don't know.
I have a huge mess in my shop....I had a fire back in Jan and while that is cleaned up I saw planning to move everything out of my basement and into a DETACHED garage I'm planning so I haven't put everything back into place...so first step is get the shop functioning again. I hadn't planned to need it for this project,
If the 713maker parts where actually available I'd probably just use their replacements where needed but it looks like a back log as they get up and running.....plus to be honest I'm a cheap !%!%$$ so........
The thickness is 1/4", I measured last night. I agree with what Ron was saying about there being nothign magic to that and Alum has advantages.....like its cheaper and I already have it so I'll look over what's broken and what is needed to replace it. A lot of the parts if not all the parts can be 1/8" and still be stronger than stock it looks like but I need to spend a little more time look it over.
