Copper Washers should be annealed before use whatever because they age harden. As they don't have an age stamp who knows how old they are. We use hundreds at work and every single one gets annealed before use.

My mate bought a set of copper washers off eBay only to find they were copper plated steel. He chucked them in the bin and used the box for something else.

+ VAT as well, on the parts and the postage.
How about these? Works out at about £10.40 for two including delivery, should be below the value to incur customs costs:

They are copper and they are sound, I'm not new to this and wouldn't compromise the engine, who says DS's are the exact spec as they were in 1976 when my bike was built ?

royhall:
Sorry Bodd should have said.

All the copper washers I use at work and on the bikes (hundreds in all) have come off eBay due to price.

Unless its a special, a copper washer is a copper washer. DSS's are in a bag with a number that's the only difference.

They still should be annealed though, but most don't bother with no problems at all. The ones I use at work are on hydraulics at high pressure that's why we anneal them.

Wouldn't have thought your bike was compromised in any way at all to be honest

The Guy on EBay selling these rubber grommets has included the 3D printer files on his eBay site to download for free! Includes the material selection for the filler wires to make them malleable.
This has got me thinking, what's to stop us from making our own on a 3D printer? I could draw the dimensions from any rubber object, it's really not difficult, as long as it's in reasonable condition and mostly there, then a prototype can be printed, and from that a mould can be made.. Grommets, air filter joints, all the N L A parts needed for a restoration!
Just a thought.
Nigel.
