CTC 10 & 11 up and running

[DaveWM]

I use wood clothspins for wedges, buy them by the bag full at a grocery store, take the two parts apart, they have a nice wedge shape built in. tap them in around the perm (lightly) making sure they make full contact (avoid pressure points on the edge of the glass). Let the pressure and the heat from the sun do the work. walk away from it after you have it all setup with wood wedges in place, come back and check on it in 30 min. Make sure you stand (upside down garbage can) is stout enough to handle the weight, do all the work over soft ground like grass in case anything goes wrong, you dont want the tube or the lens to fall and shatter on a hard surface. After 30 min of lite pressure and heat from the sun, go around the wedges and LIGHTLY tap them in again. You can tell by the sound if they are tight. Walk away again for another 30 min. Repeat this process, it may take 30min or 3 hrs, all depends on the temp and the condition of the PVA. Note all this apples to the hard RCA type pva, the green goo on zenith tubes is a completly different animal.
