Hi,
Have finally made a start.
The actual cores are coming out at 32.5g.
Also have the skins down to 22.5g before applying the inside carbon veil. There will be a little more sanding to do after the skins are applied.
Also have decided to seal them by spraying the first coats of dope - I got a new toy - a HVLP gun which works good for this - hard to believe how little air this needs to spray well.
