All of the forward spar WAF to WAF bolts (8) are AN6-5A. All of the aft spar WAF to WAF bolts (8) are AN3-5A. The forward center section spar WAF's use AN3-30A bolts (32). The aft center section spar WAF's use AN3-21A (20). The forward outer spar WAF's use AN3-27A (32). The aft outer spar WAF's use AN3-16A (20). All of the above are calculated, assuming 3/32" ply, and are for the dimensions for the KR-2S spars; KR-2's have one less ply face on the outer rear spars. Also, any control brackets attached to WAF's/bolts will need an allowance for the thickness of the brackets. Each 1/8" (.125") will need an increase of +1 to the dash number for that bolt, i.e.: standard aileron pulley brackets will need -31's and -22"s. All of these are assuming washers under the heads and nuts. Allen G. Wiesner KR-2SS/TD S/N 1118 65 Franklin Street Ansonia, CT 06401-1240 (203) 732-0508 flash...@usadatanet.net
