Topic: Home made side cover

[JS550]

This is my first attempt at laying glass, pretty happy with the result! I switched to an F oil tank, like the way it doesnt block the frame (thanks MikeB4) & wanted the other side to match, so I made up a mold. Gonna do another to get the mounting better. I used floral foam blocks to do a form, layed it in plaster of paris for the mold, then layed the glass.I'll post some more pics soon. 2nd pic is the oil tank I put on.

What kind of shocks are those?

[mycb750k6]

You're clever. You should do some CB750 K1-K6 versions. I want my first set in carbon fiber though, not glass - OK?.

[Alan F.]

Nice work.

I am but a grasshopper, I am still not wise in the ways of carbon fiber.....

HAGON slimlines, just got em, so far I think thier great! Dave Quinn is awesome, he set me up.

Very nice job. Congratulations.

It's exactly the same. You buy it in bolts like yarn or in different size meshes but it molds the same as glass and you use the same epoxy. Super light, super stiff and super strong. It's more expensive than glass though. Or you can buy a half carbon fiber half kevalar mesh. That's pretty cool too; What do you use to release the mold, polyvinyl alcohol?

Classic motorcycle Mechanics had an article, about an issue or two back, about it & they used rattle can gloss paint for a release agent. I did that & it worked really good. I had to do some work on it after it came out, but it still wasnt as bad as I expected. I read on the DOTHETON site about using the floral foam.

Here's the foam block(before final shaping), mold, & cover fresh out of the mold.

Couple more, test fit, first primer before finish working it, & on the bike painted. These close up pics make me want to paint the frame! Next winter!

anything with a wax works as a release agent.  I work at a composite aircraft company and we use a floor wax as a release agent.... granted that is R&D... but none the less.  Just remember to test out anything that comes into contact with the foam.  Some paints react and eat the foam mold.

[JS550]

Thanks for the info. I will try wax on my next try.

very nice work. vasaline works well as a release agent

Nice job on the side cover.  I like what you did with the tank too..

[madmtnmotors]

It looks like the stock tab/grommet mount points were not used. How does the new cover attach to the bike? Nice job by the way.

  Great job!

I used to make carbon fiber racing propellers years ago and the mold was in two half's that bolted together for both sides of the airfoil. Before laying in the carbon. the mold surface was coated with ordinary car paste wax and then a layer of polyvinyl alcohol which dries to a thin green film but the high pressure molds released immediately. Makes razor thin prop blades though.

Would you post a close up of your Hagon shocks? They look like what I have that I've been trying to identify.

Thanks.

Right now it is just zip tied, Im gonna get on it this week to figure something else out. I dont want to cut the original cover mounts off, so Im trying to figure out a way to utilize them. Im gonna try to either use a clamp from the back or epoxy a tab on to bolt the cover to the grommet. The F oil tank actually used the rear mount from the K on the frame & I used a rubber coated clamp that wraps around the frame tube just under the rear of the tank. With the F fuel tank on there, being longer then the K, it hides it pretty well. Thanks.

My shocks are the 2nd from the lef, with the mounts for a CB of coarse. The first two sets are the same, just different color springs. The top is a two piece collar that has "HAGON" molded in both pieces. The preload notches are hidden under the bottom collar with the hagon stickers. I will get close ups of them on my bike & p.m. them to you later.

What did you use for the mold? Is it plaster of paris?

[bassguitar333]

Make me a pair! very nice work, Grasshopper.
