First I had to draw a center line down the spar bar, line it up down the holes in the lower bulkhead, center it and match drill the #30 & bolt holes. Easy just time consuming.
Next was to square up the I believe they are the 605C bars and match drill them to the spar bar. Be careful on which holes to drill and the length of the pieces. It is best to wait on trimming the taper and ends until the holes are drilled so that you can verify proper edge distance.
I also cut the tiny spacer with the grain going the correct direction. The plans have you notch a tiny bit into the spacer, like 3/32x 1/64 deep, tiny. The best method for this was to use the big file with the line to cut off against a scrap piece of aluminum from the spar bar. (See photo) . This worked wonderfully and gave me a nice little notch.
Everything clecoed and aligned, I drew a centerline down the spacer piece. Aligned it in the bolt hole, clamped the crap out of the hole piece and carefully drilled through the spacer. It worked great!! That's it for today.
