    JB Weld time

    Just got the complete rubber set for my '82 1100e's side covers. Time to break open my package of JB Weld PlasticWeld and give it a go. Some questions:

    1. Step #2 is "...knead putty with fingers..." My hands are pretty cracked, and it's a "skin irritant." It says "wear impermeable gloves." I have a lot of medical type rubber gloves, I know they'll give enough protection, but I was wondering if they will react with and change the putty. I'll let you know.

    2. The instructions say it "can be molded or used to build up and repair" plastic. So missing side cover tabs can be re-created?

    Fortunately I have a sizable collection of side covers (six), but I love each one and won't allow any to be trashed.

    I'd just like to hear from people who've used "J-B Weld PlasticWeld" to repair and re-create missing side cover tabs.

    I couldn't tell ya anything about the JB Weld product but I have useed fiberglass resin with great results. But all I needed was to reattach a tab.

    I too would like to hear about the JB Weld product.

      If you have a good anchoring tab consider rare earth magnets. Much less messy and stronger than Hell......

            The gloves shouldn't affect the putty.

            There are lots of threads on side cover repair, see if you can find some. JB Weld will probably work fine but most people have the best luck with ABS plastic mixed with acetone into a slurry. To rebuild posts, tabs, and whatnot, bond a replacement object (e.g. piece of wire, plastic tab, whatever) to the cover with the ABS slurry. This method works best because the side covers are made of ABS, so the repair bonds well and has the same amount of "flex" as the cover.

            I'm not too familiar with the JB Weld putty, but I'm curious if it will "flow" well enough to make an effective repair.

              Cool idea, how are the magnets fixed to the panels?

                  I'm thinking I can create a little JB molehill on the cover sites of missing tabs, wait a few days, then do some sculpting with the Dremel I bought and only used once.

                    It will work for a while but epoxy has limited sheer stress capability.

                    Lay mans translation it will break off

                      From what I can remember, JBWeld plastic epoxy flows pretty quick. I think it would be kindof hard to re-create a tab on a side cover using this stuff. Ideally, I think it should be used to glue the broken piece back on. If you are dead-set on using this stuff I would say try to make a little plastic piece that fits nicely into the missing spot and then gob on the JB then dremel the excess off...

                          The Magnet idea is awesome. but if you want to keep the stock tabs. Make a Mold of the tab on a good side and use legos and Acetone to make a mouldable Plastic (ABS) slurry. Poor in the Mold and let it set. I would use some pins and Epoxy (or even some more slurry) to set it in place.

                          Melted lego is esentialy the same plastic that is used by plastic welders.

                            Excuse me?? I did, and I was stating what experience I had with JBWeld Plastic-weld just in case it may make a difference in how he approaches his repair.

                            The only contribution I see you making to this thread is calling me out about something that doesn't even make sense. Maybe YOU should read the thread before you open your mouth. Or better yet, keep yourself silent unless what you have to say is constructive. Leave the Forum "policing" to the admins...

                              Sorry to revive an old thread, i'm in the same boat with this but making the acetone slurry doesnt work here in Aus, the Acetone just doesnt do anything to the plastic at all.
