Applying glass to a mandrel?

Thanks for your interest and help.

Just about got everything ready to layup a 40" boom on a mandrel and wrap with video tape.

Is it best to apply the fiber layers one at a time or "stack" the layers and apply all at once?

I would do it with 1 piece that would make multiple circuits around the mandrel.

I lay the fabric out on the bench and roll the boom away from me.

I lay the boom down and get the fabric started along the length of the boom. Then in one motion I roll the boom quickly away from me and the fabric should come off the bench and roll up on the boom.

No. You just to make the 1 piece wide enough to so it goes around the mandrel 5 times. You will want to wrap is very tightly so there isn't air trapped between the layers.

When you get to the rolling part ,,try placing some thin foam under the layup and push down on the mandrel when rolling and you will see a improvement in the rolling process. It really helps to get it onto the mandrel without sags and air pockets.

There are a few helpful tutorials posted here on the forums somewhere.
Soller Composites have some tips on there site as well. I've done booms using their socking and heatshrink. It worked well.
