Acoustafil
So I've got a re-packable silencer, and have bought some Acoustafil PTX to re-pack it ahead of Blyton on Thursday.
My silencer is a 6" silencer, with 2" perf tube, and 600mm long. According to their calculator
(http://www.thermalvelocity.co.uk/calc/calculator2.html) I need 1.88m, so I ordered
2m. It arrived today, and each 1m roll is 5" in diameter rolled up as shipped.
When you look at pictures such as this one: -
It seems to suggest a very loose wrap before it expands. As far as I can see, even half of what I need will be a tight fit before it heats up!
Has any one any experience of this, and how much would you expect to use in a typical 6" silencer?
Thanks
Simon

This thread will help, I had the same problem, you probably need just over 1/2 of
what you have.

Im sure I have read on here before that that calculator isn't very reliable!

There calculator is rubbish - I have plenty of spare to repack in the future having ordered what there calculator told me I would need! I made it look
nominally like the 'before' photo, and it worked a treat.
