Time for an update;
Progress has been surprisingly good and problems have been overcome. Bottom mirror cell box is built and even spraypainted matt black inside. The mirror mount cell is also built and painted with my 'patented' 6 point mount. The truss poles are all acquired and the clamps that secure them inside the cell box all made and fitted.
The spider looks like it's going to be based on this link
http://www.swayzeoptical.com/spider/spider.html with elements maybe of this

Out walking and came across a piece of formica clad custom wood which will be the turntable and the teflon bearings are from a automotive high pressure compressor gasket I acquired on Trademe for $15.00.
Built a helical Crayford using the fine screwed barrel from an old video projector combined with some optical parts from a microfilm reader, the thread of which was perfect match for the eyepiece mount. Has about 20mm of thread depth but I'm sure I can extend that with other ideas if necessary.
Just need to build the upper assembly, the altizimuth mount and import some mirrors. Bintel will have my requirements at end of August.
I'll post up some pix later when I sort them out a bit, there were a few abortive sidetracks which had to be redone.
Best advice to any budding telescope builder. Get a drill press !! Mine is cheap but it has allowed me to set up jigs and drill accurate holes to replicate parts and keep things accurately assembled. My wee lathe has done stirling effort with the optical modifications but that is my penchant for building it all myself and the challenge it presents.
