Spar do-over, part one

Now that the shop is cleaned & organized, and the winter concert rush is over, back to work.  Tonight, started the nutplate attach process on the new spars; drilling holes to size, deburring, and priming in advance of attaching nutplates.  Ought to go faster the second time, right?!  I think I will use the Van’s method of countersinking (use the nutplate as a guide), rather than the jig method, this time…I’ve read on other build logs that it’s worked fine with no adverse results, and it *has* to be easier…
