Made a bit more headway on the old twin over the long weekend, but first we had two days rest on the boat (when you're on the boat you can't work on anything, therefore you rest), then came home and divided my time between the old twin and the wife's Sprite. Made great progress on both.
Here are the frame and swing arm after several more hours of grinding, sanding , priming and painting;
It feels good to be at this stage, now as parts are prepared or purchased, they can be bolted to the freshly painted frame, it feels like all forward progress from here.
