I know this has been talked about before but I could not find much in the “not so” archives.
I am on Sec 28 and it is time to mount the forward fuse section to the mid fuse section. The plans don’t say much about the bolts but from the looks of it we are supposed to use the actual bolts that attach the wings. I went and bought some alternate ¼ - 5” lag bolts but I cannot find any 9/16’s bolts at the usual lowe’s, depot, ace places. I am also somewhat hesitant to use the ¼ bolts that I bought cause they will not go through without force. Plus the machining on them is nothing like the mil spec ones. I wonder if it would just be a better idea to buy another set from Van’s? I imagine they aren’t cheap though (no shipping for me they are 20 minuets away).
What does Van’s do with the quickbuild fuse kits? Is your attach hardware in them when they come? Do the bolts get marred up at all when you install them?
I would appreciate any advice and/or what I did’s.

I don’t remember exactly what the plans say, but we use non-AN bolts to hold them together, usually 2 top and 2 bottom on each side, using the smaller bolt holes. To line them up, you can grind down the threads on a bolt or two to use as a drift pin to drive (gently) through to line them up while you put your other bolt(s) through. You will want to use grease some grease. When it comes time to install the wings, everything has always lined up very well. If you are close to Van’s and want to use the AN hardware, I would recommend at least getting the smaller bolts (they are bigger than ¼”, aren’t they?) and using them. If they line up, in my experience, the wing bolts will go in just fine when it comes wing installation time. Make sure to use washers so at to not mar the center sections, and make sure to remove the plastic from the spacers and to debur the edges of at least the outer spacer on each side for the same reason.
This is just how we have done it, and I make no claims of it being “the right/perfect way”. It has worked for us, but YMMV.

I was thinking one thing and typed another… yeah they should be 3/8’s not 1/4 inch.
Thanks for your comments Jesse.

Runs in my mind these are close tolerance bolts. My concern,with using Lowe's hardware to line things up is if things didn't line up exactly and the close tolerance bolts didn't fit after riveting you would be one unhappy camper. Putting the factory bolts in the freezer seemed to make them easier to slide in (may just have been placebo effect.) Deburring the spacer plates and taking the slight manufacturing warp out of them helps as well. If you want new bolts here is a link to Van's spar bolt page http://www.vansaircraft.com/cgi-bin/catalog.cgi?ident=1182176179-2-327&browse=hardware&product=ctbolt.

Here's what I did on the gear mount brackets, and plan to do for the wing attach bolts.It worked very well on the gear brackets.
If the "guide pins" made this way cannot just be pushed or driven through and out the other side, use something else that can be pulled back. perhaps a hole through a longer pin for safety wire to pull with?
Get hardware store bolts of the same nominal size and the same or slightly longer length.
Grind off the threads and make a bullet shaped end.
Cut off the heads and square up the cut.
Polish the pin, especially the ground part, on your Scotchbrite wheels.
Coat with grease. I used Lubriplate.
Insert with care. Push and tap in until there is room behind the squared off end to insert the permanent bolt.
Put all the guide pins in before any of the permanent bolts.
Push the guide pin on through with the permanent bolt.
Hope this is of use
