10mm wheels (theyre kinda big, gabriel inspired, so making them thicker would greatly increase weight), and no common welder (or knowledge how to use it).

I do have a Laser we use for welding at work, and some basic knowledge to do simple stuff with it...
But being a dental technician, that thing is for really small parts, even impossible to use without looking through a microscope just from the setup. i don't think that would be up to the job, since i could weld only the surface, and not get deep into the material.

welding a plate on something like that (or just the nuts i have, don't see much difference if i use the screws through the plate for main connection anyway) would have been my first idea, just getting that straight so the wheel won't wobble around and making a good weld are my problems there. So, since that really takes a lot of time per piece to make with the laser welder at work, i'd hoped for some more ready solutions, since i figured i might not be the only one with that problem.
But if there isn't, i'll have to try and just get better with that.


Oh, additional tools available are about anything you could put into a Dremel on extacy and some proficiency on using it, as well as some basic hand tools and a cheap drill press. might be able to use some more tools from work, but can't imagine which one could be useful there. About all metal works we do there is "casting -> dremel if needed -> polish". and casting these parts didn't work out so far and is a pain to do, since i can't reuse the mold.
