The first order of business was to take off all the clamps from the slats and see how it all went. I positioned the slats on the shoulders to get a glimpse of what it's all eventually going to look like. I liked very much what I saw. I kind of regret not making the initial slat wider and cutting rebate (rabbet) grooves to prepare for the side pieces—like I did on the gunboxes—but we will see what happens when I get to that point. (Rainier looks a bit like Mr. Burns from the Simpsons, doesn't he? I need to trim his hair.)
I found these nifty things called Snap Caps from a company called Pro-Dec (http://www.pro-dec.com), and ordered 100 of their 5/8" chrome caps. The caps "snap" over a corresponding plastic washer, which is held in place by a screw or bolt. I ordered 100 of the Flat Bottom "A" washers which will fit an M5 bolt, but you can get a larger hole size that will fit an M6. All together, these 200 parts cost me $35.00.
I had a 5/8" forstner bit I was going to use for drilling the bolt holes. I tested this out on a scrap piece of MDF, but it was too tight of a fit, and the cap would always get lodged in the hole at an angle. I needed a slightly bigger forstner bit, but the next size up I had on-hand was 3/4". That was too big. I needed something in between, an 11/16". A search of the Lowe's website revealed that they didn't have that bizarre size.
I had heard from my friend Jeff about how he bought RAM for his computer through Amazon Fresh (normally used for home-delivered groceries), and it was delivered same-day to his door. I decided to try it out, and see if I could get an 11/16" forstner bit delivered to me. And I'll be damned if it didn't work. They happened to have one in stock, and about four hours after placing the order, I got my bit delivered right to my door. Magic.
