RX_1 HOOD REPAIR

[snodog]

I,ve got hood repairs/plastic welding to do and need to know what type of plastic RX-1 hoods are made of. Looked in Yamaha brochures but didn,t find the info I need. Any tips would be helpful also. One plastic hinge is broke off and the other is cracked. Thanks Snodog

In the past, I have used epoxy and fiberglass netting/material. I have also used fiberglass resin versus epoxy. Epoxy dried quicker.

They also have the correct material for these repairs. It comes in a double tube and you have to have a double caulking type gun to mix it evenly and apply it in the correct proportion. A mixing tip is used on the gun. The gun cost about $75. I still have it on the shelf and I think some spare tips. The materials were about $40. For the life of me I can not remember the name of the stuff.

Consequently, you now know why I recommend expect and fiberglass.

However, repairing a hinge will be tricky. You may want to incorporate some stainless shim stock in the fix. This will add to the strength.

The molding lists 'PP + T20' on mine which is Polypropylene with 20% talc.
