Epoxy

Post by RobbieB » 30 Jun 2019, 14:26

Is anyone aware of any problems regarding the compatibility of laminating epoxy and blue foam.

I'm ready to glass the canopy plug for the M100 and I would rather do it in epoxy than polyester. Also, I wouldn't have to tape the plug first.

As far as I am aware, there are no problems with using them together. Phil at Cloud Models uses both all the time.

Robbie,
I glassed my blue foam ASK21 fuselage plug using epoxy resin with no problems.

Robbie, I used epoxy rather than polyester for the canopy mould for my BG135. I also used cloth rather than mat thinking I was being smart. BAD MOVE!
When heated during the pulling process the epoxy shrunk and left me with a pronounced weave pattern on the finished canopy. Barry at Sarik put me right!
Brian. :)

Yes, Brian is correct. The weave of the cloth / matt will show when you pull the canopy.. I now make canopys from MDF and when shaped brush on 3 coats of aluminium loaded casting resin, rub back to smooth finish and hay presto.

That must be a son-of-a-female-dog to carve and sand to shape?

They are milled from MDF. Not if you wear a mask!
