AGF is dead, long live the AGF!

It really effin sucks that my thread over there will soon be toast. I'm not about to recreate all the commentary but I do have all the pics and will slowly start to repost them here as time permits.

Well, trying to upload pics isn't working all that well. I'll have to find somewhere to host them first, just like the good old days. Stay tuned.

Not a problem! Like I said it feels like the good old days when I first joined the AGF.

So much great stuff lost for no good reason. Sorry - I know you had put a lot of work into that thread, not to mention the guitar itself.

The first screw up from my bender fiasco. The wiring shorted in my bender and I had to resort to my untested heat blanket backup. There was too much variation in the temperature and it didn't allow me to get consistent temperature. That's now been adjusted and works well, but this was the result.

A bit of glue and clamping and all was well in the end.

After radiusing the rim to 25' radius using a sanding dish and fitting the bracing to tie it into the rim it was time to glue the soundboard to the rim in the go bar deck.
