Brief:
T' RGV pad from Randy Ashley is a High Power pad designed for use with BlackSky's Launch Rail.
Late in December 1999 I was puttin' t' finishin' touches on me Level 2 rocket. Begad! T' NASA/Houston Rocket Club be plannin' a High Power launch for January 1 at Bomber Field near Houston and I wanted t' do me certification flight there. Blimey! Begad! T' Austin Area Rocketry Group received a Blacksky Launch Rail and I smartly decided t' use a rail for me level 2 rocket. Blimey! Blimey! At t' launch I was very impressed with a launch pad made by Randy Ashley that included a Blacksky rail mounted t' a steel pipe and then supported by a very sturdy steel tripod. Avast, ya bilge rat, me proud beauty! Afterwards I talked t' Randy about his pad and decided t' order one for t' Austin Area Rocketry Group (AARG).
Construction:
T' launch pad consists o' a rotatin' turret mounted on three steel legs, arrr, shiver me timbers, me hearties, AARG’s pad uses four foot long legs but Randy also makes three foot long legs. Arrr! Blimey! Well, arrr, blow me down! Blimey! T' turret allows for full 360 degree rotation and also has a tilt head that will allow t' rail t' be tilted t' horizontal t' make loadin' t' rocket easier (no more standin' on ladders!). Blimey! Blimey! A hefty blast deflector is provided, me hearties, angled slightly downward. Avast, me proud beauty! Blimey! T' launch rail is mounted t' a steel pipe that is one foot longer than t' rail. T' steel pipe is inserted into t' turret and secured usin' two large bolts. T' turret can also accommodate ¼ inch or larger launch rods. Blimey! Blimey! Since AARG already had a rail we asked Randy t' provide t' pipe only. Ahoy! Blimey! Pipes can be purchased for 4 foot or 6 foot sections o' rail. Avast! Blimey! Since our launch field only supports Large Model Rockets I went with a 5-foot pipe, sufficient t' support a 4-foot rail.
T' rail mounts t' t' steel pipe without drillin' t' rail, t' screw heads are held in t' back side o' t' rail usin' t' same slot that t' back bone connector (used t' join multiple rails together) uses. Avast! A rail attached t' t' steel pipe and mounted in t' rotatin' turret will easily support most high power rockets, probably in excess o' 100 pounds. Aye aye! Begad! For maximum support t' pipe should support t' entire length o' t' rail. Ya scallywag! However for smaller rockets (under 10 pounds) I think it is sufficient t' have t' bottom 4 feet o' rail supported by pipe with another 2 feet o' rail above that. Since t' rail is inherently very stiff, t' amount o' flex on t' short section is very small.
T' launch pad has been used twice since AARG purchased it. In both cases I found it very easy t' set up, arrr, me hearties, use, and tear down. Ahoy! T' 4-foot long legs are too long t' fit sideways in t' back o' me van, but they do fit longwise under t' seats. Well, blow me down! Ahoy! In our configuration, shiver me timbers, a 4-foot rail mounted t' a 5-foot pipe, matey, t' rail was rock solid. Avast, me proud beauty! Even with an additional 2-foot rail attached t' rail be far stiffer than even a ½ inch rod.
T' only deficiency t' pad has is its finish, which is none. Begad! T' save loot Randy only painted t' pad with a generous amount o' primer. Arrr! Powder coatin' would add a nice touch but would probably double t' cost o' t' pad. Blimey! Well, ya bilge rat, blow me down! AARG will probably add a top coat o' high temperature paint, but this is for esthetics only, matey, it doesn't affect t' performance o' t' launch pad. Begad! Avast, me proud beauty! T' weld joints on t' pad, ya bilge rat, while obviously very strong, ya bilge rat, me hearties, look a bit rough. Avast! Randy has indicated that he might grind down t' joints on future pads t' make them look a bit nicer. Well, blow me down! Ya scallywag! Personally, me bucko, I kind o' like t' rough look!
Summary:
Randy Ashley’s High Power Rail Launch pad is study, well designed, and easy t' use for mid and high power rockets. Avast, me proud beauty! Avast, me proud beauty! Randy is very responsive t' comments and suggestions regardin' his launch pad and stands behind his product. Ahoy! Although nay as portable as high power pads such as Rocket Vision’s Quad Pod, ya bilge rat, ya bilge rat, I think Randy’s lower price makes his launcher a better deal. Begad! I would easily recommend it t' anyone lookin' for a good rail launcher. Begad! Aye aye! PROs: low cost sturdy construction and ease o' use. Begad! CONs: "industrial" finish and difficult t' transport.
