Speedo rebuild

I'd rather rebuild an engine any day.... but I have a pile of CB77 speedos so I figured I could make a really nice looking and working one. I have a friend who works in the printing business, and I gave him a face . He scanned it, researched all of the fonts used, and printed the resuts on 50,000 year archivable paper with same ink. It came out really nice, but was tough to cut and punch holes. I glued it on to the stock face plate. To remove the chrome trim ring I used a heat gun, and slowly heated and pried my way around until trim could be removed. A piece of cloth over pliers, and a good strong pull got the needles off. I the removed the e clip on non gear side of odometer, and was able to reset milage to 000000.0 . All of the parts inside are very sensitive to being bent, so extreme care must be used when doing all of this. Before installing chrome trim, I put it in my cafe, and went for a ride to make sure all worked well. It did, and now it's all sealed up and ready to install in my stock resto. I'm having more printed, these are 64 style, and he's going to do one in exact opposite colors for my cafe bike. It will be a white face with black numbers and script. Me and Deez are also looking into silkscreening this artwork onto the aluminum faceplates, which is the right way to do it.

Hi

How did you manage to get the chrome bezel back on and folded over ?
I've asked a couple of speedo rebuilders here in the UK and none of them will
attempt the CB72/77s.
Most of my spare ones have pretty dodgy chrome but it would be worth getting one
rechromed if I knew I could get it off and back on in one piece - and redo the face as well.

cheers

Phil

You could get them done digitally on styrene for a lot cheaper than screen print

Eye, you might as well be speaking Japanese, as none of that makes sense to me! I'll forward the thread to Deez, as he's the graphic artist. He has a buddy that does silkscreening, and supposedly will do it on the cheap.

Phil, I used a small hammer, while pushing down on the speedo unit, and slowly worked my way around till all was snug. That's the easy part! Removal without cracking the trim is a B----H ! The heat gun, a pair of gloves, and a couple gradually larger prying tools, and oh yeah, a boatload of patience!
