[NSRCA-discussion] Wing Cores

[Jay Marshall]

I tried the contact method with the JWR Blue adhesive last night; I coated
both balsa and foam surfaces, waited 15 minutes, and pressed them together.
Worked fine. Now I have to make a choice between this or epoxy for sheeting.

I used 3M-77 for years because it was quick & easy. Contact cement is very
unforgiving and twisted / warped wing panels needed to be dealt with
occasionally. I am somewhat more patient now and use finishing resin epoxy.

I will be interested to see how you come out if you have the foam supplier
cut your cores. High taper ratios ( two or more ) call for smaller cutting
wire. Who and where is the supplier located - I need some foam ?

 

Is the the JWR Blue adhesive similar  to 3M 77 contact adhesive ? If so you
want need the vac bag. Most builders use epoxy or polyurethane glue for wing
skinning.            Nat

Thanks Jimmy. I found a local source that provides foam board, blocks &
shapes for many applications, including packaging and constructions forms.
They cut four blocks of 1# to 4X36X18 and then gave me a can of glue to try
- all at no cost. Great people to work with! They can even cut the wings if
I provide the masonite templates!

7 sheets in Nashville. Mix of 0.5 and 0.9 oz foam (virgin). Company was EFT
