That's just beautiful workmanship Jo. Very inspiring to see what young minds can achieve when they put their minds to it.
You might have to start taking orders and start a production line.
Look forward to the first light report.
Edit: I'd suggest using a nylock nut for the secondary centre bolt. that'll keep your tension constant and allow the secondary to be rotated during collimation.
with the 4 bolts and nuts, won't you have to hold the nut while tightening the bolt? might be easier if you glue the nut or add a thread so you just need to adjust the bolts.
Cheers
