Also... its important that the 3 side clips around the primary don't apply pressure on it - this pressure will distort the mirror. It should be an easy smooth fit to slide in.
BTW the sawdust finish inside works - I have seen a scope like that. Not pretty but very effective at maximising contrast.

One of the scopes is destined for my daughter, aged 5 but probably 6 by the time it's finished
. She is going to decorate the tube, which will be ... interesting! It will probably be used mostly for lunar and planetary. The second scope I will probably donate somewhere, not sure where yet.
Yes, the mirror is held onto the base and side clips with silicone glue. It is basically floating on these glue pads and makes no other contact with the cell. An obvious caveat of this is to maintain 'this way up' at all times!
