Clock Restoration

Had a go today at taking my rev counter to bits to clean up the face and glass. I even managed to prize off the sealing ring without cutting it. All went well until I put the sealing ring back on! It lets the clock down by looking crumpled and tatty. Where can you get new sealing rings and what's the technique for sealing them without ending up with a crumpled mess?

I actually enjoyed the process and I even thought I'd done a good job until I started pressing the ring back on. Is there a secret to crimping the ring?

i used a big pair of adjustable pipe pliers,and just turned it over in a few places to hold it in place,then turned inbetween each crimp.worked for me when i put new clock faces in off big fluff. :)

BigMac, some intrument makers/ repairers have a 3 roller jig that they just wind a handle and there you have it. Each roller has a groove shaped to match the final shape of the ring. Even some professionals leave the ring in pretty poor condition, keeping the "mess" to the back. There is a split clamp ring on the market that has a small clamping screw at the rear bottom. it doesn' quite look the part though!

Often, you have to get the tacho & the speedo done together, to ensure a matched set. The rings are as scarce as pelican sh*t. I have seen them in Stainless Steel or Aluminium and of different thickness'.

Don't be discouraged with your efforts, I have seen some neat jobs, usually after a few attemps. You are tackling one of the hardest parts of a restoration. I agree with Hillbilly "Patience is the key..".

Anyone know if these rings are available?

how about buying a cheap clock [z650 are cheaper], then use the ring off that. i know its a time thing, but its a possibility.

RE that e-bay sale....Sorry BIgMac, I'm not so sure after a closer study of that ring. Maybe the H2 has a different OD. Also, from the photo I don't like the width, the depth or colour. I did tend to jump in! Perhaps, you could ask the seller the question.

Garn,

Klasmo stock closing rings (part no. 250000Z) but I'm not sure whether they are the same as the original and they are not cheap!

I too, would love to find a way of getting a presentable finish. What does this 3-roller jig thingy look like?

Cheers,
Andy

Maybe you could ask zpower or other z supplier in the U.K to stock some from Doremi.
