1708 mat for stringers

[Kracker Jack]

I put a layer of 18oz woven against the skin,I then let it kick slightly and then 1/4 inch notch troweled my thickened resin on and clamped my first layer of core. The reason I put the 18 oz on was to make up for some thickness lost due to grinding skin for prep. A dusky build on THT the guy put 3 layers of core and incorporated knees in his stringers as one piece.
