Luckily, I've been able to make everything I need with plywood, pvc pipe, muslin, fabric dye, a table saw, a handsaw, plastic storage containers, and truckloads of duct tape... Damn, that list was longer than I expected.
I may be restoring a beat to hell enlarger this summer. If I need something that I cant find anywhere else, perhaps I'll add something useful to this thread
Edit: I made this coment before looking at your site. I dont think DIY camera kits would help me in restoring an enlarger
