Glueing washers inside the tube…
I have an aluminum tube and to make the baffles in it the washers have to be glued in there, right?
I’ve read somebody asked the same question and the best glue was JB Weld for that.
Well, I have couple of questions. How would you glue them inside of the tube perfectly squre (90 degree to the tube) to avoid clipping?
And how would you deliver glue that deep inside? Would you apply it on the washer first and inside the tube, and slip the washer in? Or would you hold the washer inside the tube and apply glue with some long aplicator?
Or are there some other effective ways?
Thank you

I may have been the one who started the thread you read. I ended up making a nice 1 piece unit using some random 2 part epoxy I had among my paints and glues. I ended up using pieces of spring to hold my washers in place while the epoxy hardened. 1 washer at a time was placed, glued, and waited on for the epoxy to harden before the next washer. I have 3 washers in the tube, the first washer being several inches from the barrel so as to allow for a BIG first chamber. My front bushing is vented as well so chamber 1 has some serious volume. Chambers 2 and 3 are progressively smaller. The results are fantastic, very quiet. The epoxy seems to be much stronger than necessary, its just some 5 minute stuff I have had for years.

You dont need to secure each washer – just the end’s. If I didnt have a drill press, tap, mill and a lathe……. and just use some JB weld, washers, Aluminum tube and springs plus other inexpensive parts from hardware store I’d start by making 2 “bundles” of washers stuck together with epoxy and let them cure. Then one goes deep inside the shroud placed square using a 1″ OD wooden dowel the length of the first chamber – measure and cut the dowel so the first bundle of washers will clear the barrel, then put some epoxy on the outside of the bundle and the inside the the tubing. The epoxy on the inside should get squeegeed up the inside the tube. The tighter the fit of the washers and the longer the bundle the better as that will hold it square in the tube so you wont need to keep the dowel in place. If you do need to keep it there, just spin it now and then to stop the dowel becoming a permanent part of the shroud. Then when that has cured, use springs/washers and then orings/washers to create the baffles until you you run out of space. Use the second bundle of washers you made and epoxy that in as an end cap. If you have a pipe clamp.. use it…. If not, then you should be able to jerry rig something to keep the end cap in until its cured.
