Well actually I don't have any sawdust yet. I've been scraping and wirebrushing and applying rust converter. I bought a Harbor Freight flux wire welder for $89 with my coupon. Now I can reattach the fender that came off and maybe strengthen the frame some.
My local lumber yard says they have some 1/2" exterior fir ply, not common around here, for cheap because the school board stopped ordering it. That's where I'm going tomorrow.
My problem is the garage, it is full of stuff. Including a motorcycle that didn't sell on ebay. That sale would have financed a bigger better Benroy. Oh well. I may get another canopy and start the woodwork in the back yard, (this is Florida) That way the sawdust can blow over to the neighbors yard.
The plan is for a 4x8 modified Benroy with 1 self built door, a horizontal slider window on the other side, a half hatch meaning not all the way to the rear bottom, an A/C slide out on the rear side (under the galley) and fiberglass finish.
Comments, ideas and suggestions welcome.
