Mid Fuse Ribs & Bottom Skins 26-1 to 26-7-3

With the mid fuselage bulkheads assembled, I moved on to section 26 of the plans and started working on the ribs that connect the bulkhead. After locating all the parts, I went through the usual motions of deburring all edges, and drilling and countersinking the necessary holes.

After cutting, drilling, countersinking and deburring all mid fuselage bulkhead parts, I was ready to prime them all before final assembly. However, all the priming I had done until this point had been outdoors during favorable weather (~ 65-70 deg). Now being the middle of winter, the weather wasn't cooperating so I had to find a way to prime parts indoors while containing any overspray. I found a medium sized collapsible spray tent online, and put together a small spray table that would sit on a couple of sawhorses. The tent has an opening in the back that allows me to insert some air filters, and an extractor fan I purchased helps to pull away any fumes and overspray. With this setup, I was able to successfully spray all parts while staying warm in my garage.
