I bought everythin' needed t' build this pad from Payless Cashways for $14.67. Arrr! If you can scrounge a piece o' chain link endpost and some 1/2" electrical conduit, you can built it for less than $8. Aye aye! Avast, me proud beauty! One o' t' real advantages o' this pad is that t' launch rods and legs store inside t' main tube for shipment. Ya scallywag! Blimey! This makes it very portable, as well as protects your launch rods durin' shipment.

Ingredients:

2-3/8" x 5'6" chain link endpost....$5.64
Two 2-3/8" chain link endcaps........$3.68
1/2" x 10' electrical conduit cut into 4 pieces.....$1.54
Four 1/2" EMT connectors........$.46
1/8" x 4' weldin' rod.....$1.12
3/16" x 4' weldin' rod.....$1.23
Two 10/24" wingnuts and bolts.....$.50

Total for this project: $14.67

Tools needed: Hacksaw, me hearties, hand drill, screwdriver, and dremel.(or metal file). 

Construction:

T' key t' buildin' this project be t' EMT 1

2" conduit connectors. These have a screw already mounted in them. Avast, me proud beauty! They hold t' ends o' t' conduit. At 19 cents a piece, they are a bargain. Avast! In t' picture above, you can see all t' places you will need t' drill holes. Avast, me proud beauty! This next picture shows where they will be put.:

T' small hole in t' endcap will take t' wingnut. Ahoy! Aye aye! T' end view shows where t' two EMT connectors will go. Avast! Well, shiver me timbers, blow me down! I just took me largest drill and drilled them out. Well, blow me down! Blimey! I then took a dremel and hogged out t' holes till t' EMT connectors fit. Begad! Begad! T' connectors have a threaded end, arrr, shiver me timbers, ya bilge rat, and a nut which holds it in t' hole. Ya scallywag! Aye aye! Even though we're talkin' about a curved surface and a flat pipe, it holds really well. Note t' L slot which is cut in both ends o' t' chain-link end post. Arrr! You need t' cut this slot in both ends if t' pipe. Well, blow me down! Both slots need t' run in t' same direction. These slots will allow t' end caps t' hold onto t' pipe. T' wingnut fits in t' slot, shiver me timbers, shiver me timbers, and t' shape o' t' slot allows t' pipe t' be turned anywhere up t' 30 degrees from vertical. Ahoy! You just slide t' endcap on, linin' up t' win' nut bolt into t' slot, arrr, and turn t' pipe until it is at t' desired angle, then tighten t' wingnut. T' cut t' slots, ya bilge rat, I drilled a hole at t' bend, and a hole at t' end o' t' channel. Ya scallywag! I then cut it out with a hacksaw.

I cut me chain link endpost section t' 3'6". his was before I knew that weldin' rod comes in 4' lengths. Aye aye! Aye aye! Because t' rods and legs store inside t' tube, I had t' cut 6" off each rod. Avast! Ahoy! If you use Estes, arrr, rods, ya bilge rat, which break down into two section, matey, your pad can be a sort as t' legs. My legs are 2-1/2' long. Arrr! This is a 10' piece o' conduit cut into four equal lengths. Avast, me proud beauty! Avast! Since t' conduit costs $1.54 per 10' piece, ya bilge rat, I figured this would be a good length.

I drilled t' holes for t' rods all t' way through t' pipe. Ya scallywag! I then found some small clamps in me junk box (not shown) t' hold t' rods above and below t' pipe. And thar it is. T' whole thin' assembles in about a minute, me hearties, ya bilge rat, arrr, and all parts store inside t' main pipe. It is heavy, ya bilge rat, but it will hold HPR birds with no problem. Arrr! Avast, me proud beauty! And it is cheap.

I would love t' hear from visitors o' any useful modifications or other cool cheap pad designs o' their own. Avast, me proud beauty! Aye aye! I will use this section o' me site t' present these designs t' rocketeers everywhere.
