[Dobman (Simon)]

I'm considering converting my 12 inch Bintel Dob to a truss design.
My main considerations are:
1. more compact for storage and transporting.
2. Easy collimation.
3. Wooden construction ( I'm more confident in woodworking than metal).
4. Simple design.
5. reusing the main and secondary mirror and focuser.

I've been searching the web for step by step plans but without much luck.
Can anyone point me in the right direction to websites etc.?
Thanks in advance
Simon
