Default bolts

I used four 3/8" hardware store bolts. I ground off the threads and tapered the ends slightly.

Worked good. I would NOT use the tight tolerance bolts for a test fit...

Hardware store bolts----get them longer than the actual bolts, cut off the threads and taper/round off the end.

Thanks. I have the 4 bolts in place now as I am building the fuse so those will be the ones for wing install. Thanks

Mark,

I used the close tolerance bolts with the spacers in order to "align" the two center spar sections, while building my fuse. My thought was that I wanted them to be as closely aligned as possible, in the hopes that when I go to install the wings, the spar holes will all go together "like butter." The close tolerance bolts required patience and lubrication to work with, and it's possible I may have to buy new close tolerance bolts when the time comes for final assembly. However, I wanted everything to be as closely aligned during building as possible. I just didn't feel that "hardware" bolts would give me that. Your mileage may vary.

When you do the actual assembly with the close tolerance bolts, put them in a small ice chest with dry ice for an hour or so.

Helps......

Also, be sure the threads on the bolt/nut do not bottom out before the nut fully seats on the spar. As I recall, I had to install a thin washer on a couple bolts to get the stackup right.

I did the same. Wondering if I need to buy new bolts now for final assembly? Thoughts anyone? May put a call into the mother ship as well.

Ditto. BTW, the plans recommend doing it this way. Less chance of screwing up some critical hardware/parts. Save the close tolerance bolts for final assembly.
