I bought everythin' needed t' build this pad from Payless Cashways for $14.67. Well, blow me down! If you can scrounge a piece o' chain link endpost and some 1/2" electrical conduit, you can built it for less than $8. One o' t' real advantages o' this pad is that t' launch rods and legs store inside t' main tube for shipment. Aye aye! This makes it very portable, me hearties, me bucko, 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, ya bilge rat, me bucko, hand drill, screwdriver, matey, and dremel.(or metal file). 

Construction:

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

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

T' small hole in t' endcap will take t' wingnut. Well, blow me down! T' end view shows where t' two EMT connectors will go. Arrr! Ya scallywag! I just took me largest drill and drilled them out. Avast, me proud beauty! Begad! I then took a dremel and hogged out t' holes till t' EMT connectors fit. Ahoy! Begad! T' connectors have a threaded end, arrr, and a nut which holds it in t' hole. Blimey! Even though we're talkin' about a curved surface and a flat pipe, arrr, shiver me timbers, me hearties, it holds really well. Blimey! Avast, me proud beauty! Note t' L slot which is cut in both ends o' t' chain-link end post. Ahoy! Avast, arrr, me proud beauty! You need t' cut this slot in both ends if t' pipe. Avast! Both slots need t' run in t' same direction. Avast! These slots will allow t' end caps t' hold onto t' pipe. Blimey! Ahoy! T' wingnut fits in t' slot, matey, and t' shape o' t' slot allows t' pipe t' be turned anywhere up t' 30 degrees from vertical. You just slide t' endcap on, linin' up t' win' nut bolt into t' slot, ya bilge rat, and turn t' pipe until it is at t' desired angle, then tighten t' wingnut. T' cut t' slots, me bucko, shiver me timbers, I drilled a hole at t' bend, arrr, shiver me timbers, and a hole at t' end o' t' channel. 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. Because t' rods and legs store inside t' tube, I had t' cut 6" off each rod. Ahoy! If you use Estes, ya bilge rat, rods, me hearties, which break down into two section, your pad can be a sort as t' legs. Begad! My legs are 2-1/2' long. Avast! Aye aye! This is a 10' piece o' conduit cut into four equal lengths. Ahoy! Since t' conduit costs $1.54 per 10' piece, I figured this would be a good length.

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

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