Working on wing attachment brackets

My spring on my drill press broke last work session. I found a nice one on Craigslist, bought it and brought it
Home. Worked on enlarging the holes on the reinforced section of the spar to 5/32". I also aligned and drilled the holes in the attachment brackets for the right wing spar to the center section. Found out that I need washers for all bolts. The plans don't mention washers, but I understand that is general practice. Next work session will be cutting spar caps and assembling left spar section. I also
Need to cut and attach the angles for the ribs.
