Re: 68 Honda CL175
How do you think it will bend and what will all be mounted there that you think it will see a lot of forces? How thick is it and what kind of aluminum? Any idea how much that speedo weighs, and how exactly is it mounted? I have my own projects to work on, but if you answer my questions I may be able to do a quick rendering in Solidworks to show you the deformation from various forces. I can't imagine cutting a hole on either side of the speedo will weaken it much if at all.
To solve your teeth mark issue, you could try slipping a small thin peice of wood between the jaws of teh vise and the aprt before clamping down. Depending on the shape of the part, the wood might deform enough to hold it in place while preventing any metal teeth from biting into your parts. Just use something soft like pine. I used to have some hin copper plates bent up to slip over the jaws and just hook onto the vise but I can't find them.
This is the best picture I could fins after a quick search on google, but I meant rounded speedo like this...
I meant for the back of the speedo to be like a dome. If you can get one of these (obviously not the one pictured) then you may not have to notch anything.
Big R said:I wanted to point out earlier that I'm using aluminum plate for the speedo mount - don't want to add more holes in it and make it any easier to bend. And anytime you wanna come out and build the bike is fine with me
Being that I was out and about all day with the family I didn't have nearly the time I wanted to work in the garage. But I did get the hole cut out for the speedo for a little visual fitment:
All the edges are rough as hell and the surface of the plate has about 1000 teeth marks from the vice but with some grinding, cutting, and polishing it won't look too bad. And yes, I know the edges aren't symmetrical. From this pic you can see how the speedo won't touch the headlight but the cable on the other hand is gonna be the problem.
I might see about cutting a notch out of the back of the bucket for the cable depending on any water flow/collection issues
