I made some forward progress over the weekend.
Saturday 7/30/16 : I got 2.5 hours of work in.
I was focused on making the upper blade guide. The plans call for the blade guide bearing to touch the back of the saw blade with its round surface. I wanted to mount the bearing so it would contact the rear of the saw blade with its side on the flat surface. So I needed to rework the bearings and think about how it would all go together. The plans were little help here.
I started by spreading everything out, including the plans, and looking at it all and taking measurements. I basically emptied a bunch of different fasteners on the table to see what I had that might work.
I started focusing my thoughts and came up with the following components that I would use.
I didn't get a picture of this step, but I took a hex head bolt and filed the hex head round, and then used a hacksaw to cut a screwdriver slot into the head. The original hex head was too large and would block the potential path of the band saw blade. I filed it round to make it smaller.
