The weights of glass cloth are per square yard and do not include the epoxy

resin.

The holy grail of fiberglass layup is to achieve a 60/40 weight distribution

(glass/

epoxy) but 50/50 may be more conservative. Figure how many square yards of

surface area you have and multiply by 13.4 to get the weight of the cloth only

and

then double that to get the weight of the cloth plus epoxy. You'll only

achieve

this if you squeege out all excess resin or vacuum bag it.

My calculations are as follows :

LOC 54mm tube has an OD od 2.16" which gives a circumference of 6.754"

The 34" length gives a surface area of 229.65 sq-in or 0.177 sq-yd. Thus we

should have a weigh of 0.177 sq-yd * 13.4 oz/sq-yd * 2 = 4.75 oz.
