I plan on using these:

I have used these on some very heavy machinery. They are rock solid and stable. The scope will have to be easily moved so wheels are crucial. I have tried to design everything to minimize unwanted movement and backlash as much as possible without resorting to materials other than wood. Metal has been used wherever absolutely necessary, collimation bolts, focuser shaft, bearings, etc. The whole idea here is to have a properly functioning scope made mostly of wood. But the idea of it being 100% wood must be compromised at times to insure functionality.
