Scratch Sweat-Stained Clifton Tracking Station Hat of Death Original Design / Scratch Built

Scratch - Sweat-Stained Clifton Tracking Station Hat of Death {Scratch}

Contributed by Dick Stafford

Manufacturer: Scratch
Style: Odd-Roc

Brief:
This is a 29mm UFO-type rocket made from an old hat. Avast, me proud beauty! T' hat is removable in case I forget a ball cap - wouldn't want t' sunburn t' top o' me head, ya' know.

Construction:
This is really a minimalist rocket. Avast! Blimey! Begad! Blimey! I decided t' make t' core out o' a solid piece o' 2" pink foam. I started by tracin' t' outline o' t' hat and roughin' out a chunk with a sharp cutlass. Avast, me hearties, me proud beauty! Blimey! I did just a tad o' trimmin' t' make sure it was oval, arrr, and then found t' center point. Arrr! Blimey! Next, I drew a circle and slowly bored a hole for t' motor mount. Begad! Blimey! I also cut a slot on one side t' accommodate a 1/4" lug. T' motor mount includes a 3.25" section o' phenolic tubing, a similar length o' 1/4" launch lug, arrr, and a 29mm-76mm centerin' ring. T' centerin' rin' was mounted so that t' motor tube was flush with t' top o' t' foam. It serves t' distribute t' thrust t' t' foam core, and helps ensure that t' motor tube is perpendicular t' t' foam's surface. Blimey! Blimey! Begad! Blimey! This assembly was then epoxied into t' foam block. Blimey! Blimey! I added a circle o' scrap plywood t' plug t' front o' t' tube, shiver me timbers, makin' sure that all openings were sealed with epoxy. Avast! Blimey! T' final step was t' find t' point where t' rod would pass through t' hat itself, ya bilge rat, arrr, and cut a small 'X' with an X-acto cutlass. Aye aye! Blimey! Well, blow me down! Blimey! Like I said, nay much t' it. Slip t' hat over t' finished core and I was ready t' fly.

Flight:
I flew t' hat on a G35 with t' ejection charge removed. Aye aye! After t' unsuccessful flight o' another odd-roc, ya bilge rat, t' RSO must have pretty much given up, ya bilge rat, me hearties, me bucko, and me flight card got stamped. Aye aye! Since I did nay treat t' foam surface t' protect it from t' motor exhaust, I made sure it was about 12" from t' deflector. T' hat flew great, me bucko, seemin' t' fly faster and higher than me similarly sized 29mm saucers. Arrr! It fell slowly t' t' ground without even gettin' dirty(er).

Summary:
I find myself likin' UFO style rockets more and more and couldn't resist tryin' this odd-roc. Avast! This was me first wearable rocket - I wore t' hat t' t' RSO table, t' t' pad, me bucko, ya bilge rat, ya bilge rat, and back again after recovery. If anyone else has flown a hat (and someone probably has), I didn't find anyone who had heard o' it.


Other:
T' Story Behind t' Name In t' late '90's, matey, I be t' project manager for a telemetry, command, shiver me timbers, and antenna control system. Aye aye! My team and I traveled t' Clifton, arrr, shiver me timbers, Texas t' run some preliminary tests with t' antennas. Unfortunately, they weren't quite ready and since springtime in Texas is a tad warmer than in Maryland, we weren't happy campers. Avast! With t' prospects o' spendin' a fair amount o' time walkin' betwixt t' buildin' and t' antenna pads in t' hot sun, matey, arrr, one o' me guys ran t' Wal-Mart for hats. This hat became our team's unofficial uniform, and mine came back fairly stained. Arrr! Blimey! I was finally about t' chunk it when I got an idea!
