repairing side spanels?

[Planecrazy]

I would't worry about the plastic left to adhere to ... if you do the prep I've done on mine (described above) you won't have any problems with adhesion, even if you "butt joint" the new piece to the sidecover. Besides, once it's bonded you can always use additional epoxy to build up the base.

That is basically what I intend, except my concern is with the prep and finish.

Basically I am worried about the joint coming apart because of the way the piece is broken. I am thinking that I need to bevel the remaining piece so that the edge will hold it in. Also I am wondering if I should go with a thinner piece so that I can build it up on installing it.

Here is a simplified diagram of what I am thinking

l--\ ---------- /--l The piece is beveled facing the bike which I think will
l ---------------- l make a weaker joint
l___________l


l-/ -------------\-l Cutting the bevel the face away from the bike will be
l -----------------l more secure, but it leaves much less original plastic to
l___________l bond to.

Here you go mate, try this, it's real plastic, so it sticks to plastic better than anything, and you can mold missing parts! Cheers, Terry. :twisted:

Attaching what ain't there

Attaching what ain't there

I have had to reatach mounting bracket tabs that were completely missing. That is I had to "build on" the missing plastic. I used a detentist trick and drilled into the plastic base material and installed a wire framework to build on. I insert the formed wire, which I roughend up with plier teeth into the drilled holes coated with my choice for rebuild material. I use Resto Grip a fiberglass reinforce resin material. It is great, but expensive. After the wire framework is set on put on the Resto Grip and sand and shape to whatever shape I need. If you are skilled you won't be able to tell there was a repair when painted. The repair seems to be stonger than the original brackets. If you need further info on this technique let me know.
