Thanks for that, Phil.
I had already planned to use acousta-fil, following your recommendation a while back.
Presumably, since the acousta-fil expands to fill the can, it would be necessary to line inside of the carbon sleeve rather than wrapping the fill with heatproof tape ?
Mind you, the old fill was completely burnt away for about 2/3 of the length of the can when I dismantled it, without any signs of burning ... but I'll line it on rebuild anyway. I have some plain aluminium tape that I was thinking of perhaps using but maybe something like you suggest with a fibreglass layer would be more appropriate.
And lastly .. excuse the daft query but just to be sure .. when they say stainless rivets they do mean that just the core is stainless and the main rivet body is aluminium, don't they ?
Interesting to hear that you have successfully drilled your own rivet bands.
I was anticipating that they could easily snarl up as the drill broke through on such thin material.
I was thinking that I might use a centre-drill instead and perhaps finish to size with a taper reamer or a file.
Did you use a normal twist-drill ?
