I again repeat my advice from your other glassing thread:screw it I'll just make it out of csm chopped up.
If you are on an ultra tight low cost budget, you might want to take a day or 2 and read thru some info that's been provided & ask lots of questions. Lots of questions have already been hashed thru & posted in other threads. Reading some of them may help all this stuff make more sense, be easier to follow, and ultimately, when you start working on some portion of the resto, it won't be so frustrating & you won't 'waste' materials or time.
Probably ought to edit the text in your pix, else the pix may get redacted.....
