The place to come to share your technical expertise, or just find out what the little springy thing is that's just pinged out of sight under the work-bench.
I put an order in for 4 exhaust gaskets to a company near me. (Doncaster) Before I bought them I asked if they were made of copper / fibre / copper and they said they were. I also attached a photo of the ones I was wanting. I placed the order and they've sent me these.
Will these be ok?
This is the photo I sent them.
Bit of advice. Buy a good bed and a good pair of shoes, because if you aren't in one you'll be in the other.
Couple of those aren't circular and the outer layers are spread. Looks like Donny crap to me. Hope you didn't pay too much. Why didn't you go to Fowlers or Wemoto?
