ATM A few silly questions

[Simon Fourstar <sfourstar@earthlink.net>]

Hello All,
 So I am redesigning the 4.25". It's a real good first run, it's just not
the telescope I want it to be yet.
 On the new design. I am thinking about using a two vain spider design. I
am wondering about the positioning of the veins? Which should I go with, 90
degree or 120 degree? Are there any advantages to one or the other? Or is
it 6 of one half a dozen of the other?
 Also I want to build the focuser, I have a full tool shop to play in. I
might as well use it. I am wondering what makes a low profile focuser, low
profile? I have read about a few of the advantages, but haven't been able
to find a clear definition of just what it is?
 And, do any of you have any ideas/suggestions. On a solid stock material
that I can turn on the lathe, for the altitude bearings? Teflon? I am
reaching here, some type of plastic or similar material? If so do you know
where to get it?
 I read about one man's adventures in flocking paper. I gather that in the
summer heat, the self adhesive failed. And the paper almost fell on the
primary. Any one have any suggestions, if I were to apply the adhesive my
self? What brand would be good for this application?

Thanks up front, Simon.
