Grok has been helping me figure out how to replace CFC with aluminum tube with minimal weight increase. It appears that .5" OD .035" wall is slightly stiffer than the CFC tube that I now use for the axes. This lets me reuse my existing polar and declination housings, bearings, and drive gears.
I have been attempting to learn to use FreeCAD and no tutorial seems to get me over the first step of converting a two dimensional drawing into a 3D object. I know at least one of you has admitted FreeCAD experience. I would be quite happy to pay someone to use Remote Desktop Connection and help me past this obstacle.
UPDATE: Just realized that I do not need to replace existing housing and axes They are already cut
