Peter - Thanks for responding.
Your point is well taken. I had seen in a couple of your videos where you used the PL adhesive for attaching some internal bracing. I also noted that you said this was an unconventional use of this product. I believe in one case you used it to attach the small diagonal braces (Sorry, could not locate the video for this one) and another was to attach a dowel brace:https://youtu.be/5n3ZYGnEjgE
Honestly, your videos have been a source of inspiration for me and I greatly appreciate you taking the time to make and post these. I didn’t mean to come across as saying “Peter said to do this”. Only that you were a source of inspiration for what I plan to do.
Your use of the PL adhesive for the braces gave me an idea for how it could be used in the assembly of the braces in this speaker design. That is, use the PL for the internal braces, where there may be clearances and variations in dimensions of the pieces I have made, and, as a result there may be gaps too large to make good use of the Titebond. I do plan to glue the main part of the cabinet with the Titebond.
Here are my thoughts (right or wrong - comments welcomed.
I don’t have the wherewithal to make these braces with the precision needed to ensure that all of the pieces will fit exactly, without one piece pushing on another piece or having gaps too large for conventional glue. I see this happening with the internal braces in this speaker design where one brace may be either slightly smaller or larger than any other pieces, which may in turn affect the “size” of this cabinet. I want the “size” of the cabinet to be defined by the external panels. Additionally, I will need some “slop” in the location of the slots for the braces to absorb any misalignment from side to side resulting from any inaccuracies from locating the slots in the panels. Therefore, all of the internal braces will need to be undersized and the slots into which they will be fit will need to be slightly oversized. The PL adhesive seems to be a good solution for this application as the bonding would seem to be less gap sensitive. I am not talking huge gaps here. Maybe 1/32nd to 1/16th, but I figure any gaps of this size will not glue well with the Titebond.
As I said, I plan for the rest of the cabinet to be assembled with the Titebond.
I see this speaker as being a more difficult one to do the assembly on because of the 7 braces in it and the front panel needing to be installed at a later time, so the no-Rez, crossover and wiring can be installed. Right now I am puzzling through how best to do this within my abilities.
I do appreciate other people’s thoughts here...
