I received two MPC bodies in an ebay lot that did not survive the trip. They were like new but now are in many pieces. A real shame. I fear this is a fate that many old bodies will suffer. Just like many of the Aurora H O bodies that just shatter.

 

I started to glue one together but I could use a some ideas on reinforcing them from the inside. I was thinking of laying something in there like crazy glue or epoxy soaked cloth or something but could use ideas.

 

Not too worried about what it looks like on the inside. 

 

Thanks.

One way I've done a couple of Tamiya bodies, is to get an old pair of nylon stockings (either yours, or your partner's :huh:) cut it out to suitable size, and stick in there with the gel super glue.

 

Seemed to work ok, but never really got to test how strong it was, as it didn't see any rough action again, but it felt pretty strong.

 

edit: Added "Tamiya bodies"

I'm not that familiar with MPC bodies.

A few MPC bodies from the mid-60's were made from .020 G.E. Lexan, maybe the first slot car bodies ever.

 

With time and aging they get brittle. I know that the Ford J car and the Mako Shark were made from early lexan.

 

I believe Gene Adams might be producing repros of those bodies soon. I could be wrong though.

Sorry Steve, I'm not sacrificing my personal underthings  :laugh2:

 

Maybe I should have been more specific. These are hard plastic bodies of the Scarab and Ferrari. The plastic has become super brittle. I'm not sure on these but some of the Aurora body colors like tan are much more brittle than others. Depends on color. I imagine it has something to do with the formulation.  

 

Thanks

Sounds as if you will have to reinforce the whole body once it is pieced back together again, otherwise it could break somewhere else.

:huh:

You know Steve I was thinking the same thing. I would hate for it to break somewhere else after a lot of work. Nor would I want it to crumble in the next owners hands. 

 

I was thinking of flowing something into the body with reinforcement. I will post some pics soon.

 

Right now I am heading to the hospital as I just got word my oldest daughter is soon to go into labor with my first Grandchild  :heart:

 

And lay off the Grandpa jokes. Most of you bastards here are older than dirt  :laugh2:

The nice think about having grandchildren is you can usually send them home at night. I have grandsons age 9 & 11 who live in AZ, so i don't see them as often as I did when they lived  in western NY. :)

 

Joe, buy a pair of pantyhose at Dollar Tree for a buck. Hard body racers have had their body joints reinforced with nylons & super glue for years. Devcon sells a "Plastic Welder" cement that works well on most types of styrene, but I don't know what plastic MPC used. The "Plastic Welder" has a very strong odor.

Congratulations! Nothing better than spending time with the grandkids.  You could try superglue to tack the body together, then reinforce the inside with shoe goo or goop. It's a kind of liquid vinyl product. Really tough. Good luck.

Shoo goo works fine, but is not very light or self leveling.  The new "U-6000" contact adhesive is working very nicely in repairing and reinforcing all Vac form bodies and should be lighter for the already heavier injection molded bodies.

When I build scratch bodies from RTV silicone molds, I slosh in a very thin resin layer to pick up the detail and provide a good painting surface and then reinforce with a coupe of layers of very thin carbon fiber mat set in epoxy.  The result is strong and light. This should work on injection molded plastic as well.
