Shrox: Maybe I'm just lazy, or maybe I'm just not confident enough in my own skills to accurately cut the circles and center the holes in them. Maybe it's a lack of proper tools to assuage my lack of confidence in doing them "right." Oh, well.
As far as the impatience thing: I tend to be that way too, when I get right down and physically started on one. However, I spend far more time cruising plans, building them in my head, thinking about constructability issues, and often times upscaling. I'll tinker with the potential clone or build in my head and have it built (in my head) many times over before I physically start on one (usually.) That said, I tend to have the burners lit on several ideas at a time. When I get enough material needs due to these plans and/or ideas to place a BMS order, I go with it. I only purchase for myself, and I've not spent less than $100 each time I've ordered. But I get a lot of stuff and can build away on several premeditated projects when the stuff does arrive. So, I guess I spend a lot of time thinking and dreaming of a rocket before I actually decide to build it.
Kelly: to answer your question on the dimensions of the stuff I got from BMS -
For the antennae discs, you will need 3 each of 2 different sized discs. The dimensions that I used are: Smaller disc OD (Q) = 0.55; Larger disc OD (Q) = 0.75. Both have a center hole being 1/8" (I = 0.125) I had them cut from 1/16 plywood (M = 80)
For the detail discs on either side of the fins just above the ring fin, you'll need a minimum of 6 (may want to order an extra 2 or 3, just in case you misplace one on your build table.) Anyway: OD (Q) = 0.375; no center hole (I = 0.00). I had them cut from the 0.05" thick black letremax cardboard (M = 200).
If I didn't mention, you order them as "custom cut centering rings." There is a calculation sheet based on the size of the "rings," quantity and material used (hence me giving you Q, M, an I numbers.) Just because they are "rings" doesn't mean the have to have a center hole!
Oh, the tail ring is a 1" long piece of BT100. I got mine from Sandman when I was purchasing the cone for my Atlantis. Aside from finding someone who will sell you a scrap piece to you, the only source that I know of out there is Totally Tubular, and you'll have to order an entire 34" long piece. That said, if you have some BT101 on hand, or have another project in mind that will use a BT101 (like a Pershing 1A clone *wink* *wink*) you could use a 1" long piece of it instead, and just tinker with the fins to make it fit right (it's not very much larger, and few would notice.)
Thanks, and good luck!
