I have a 10 year old home-built Truss Dobsonian that needs a home before it
finds the garbage.

It was a 10" f5.6 scope that now has no optics, primary cell, secondary
holder (though it does have a spider), focuser, or teflon. It is very
functional, however, with these items

If you're interested let me know. The quality is certainly nowhere near
perfect - this was a college-time project. The primary mirror cell would
simply be a plywood disk with the optics glued, or otherwise mounted. You
could buy or build a secondary holder for pretty cheap. The secondary cage
unfortunately has two focuser holes (an expirement gone bad), but is
otherwise functional. A JMI will mount directly. A little paint & TLC will
make a very serviceable and nice scope. I'll try to get some pictures.
Pick-up required in Torrington CT.

Here's something I came up with:
Standard primary mirror from Discovery 10" f5.6 = $349 + $12 shipping
2.14" elliptical Secondary = $59 + $4 shipping
JMI RCF (reversed crayford focuser) kit $59 + $7 shipping
Fabricate a secondary holder = $5 (Home depot)
Teflon Magic Sliders = $8 (Home Depot)
Paint = $10 (Home Depot)

Total = ~$500

You could get a cheaper focuser, or secondary mirror for that matter.
Anyway, just a thought.
