Centuri LIA-77 Launch pad
I came across an original Centuri igniter/deflector a while back and have been trying to replicate the tripod. I've built a couple by trying to scale from photos, just can't get the look right. Does anyone have one that could post tripod leg tracings or info?
Thanks John |

John,
Legs are cut from 1/2" x 3" pine and base is from 1/4" masonite. Photo is here and pattern is here. We were going to produce this last year, but the cost would have been in the $25 -$30 range. We felt that would be too high to continue the project. We have quotes on the blast deflector. I started to order a few just so I could produce a few pads for our use. I saw an LIA-100 at TARC a few years ago. The student did not know what it was. He said he borrowed it from his Dad's old stuff. It had been well-used, but was still recognizable. I talked him into using the pad supplied by TARC and told him to go back and see if his Dad kept any of his other stuff from the 60's.

Would like to see Carl produce the LIA-100.
Several would be sold surely. I think the price for that LIA-77 sounded good.

What else did one get for the extra buck-twenty? Longer leads? 3/16" rod? Doug .

I'm pretty sure everthing on the 100 is up-scaled. Nothing is mentioned in this catalog page in the deflectors being different.

It was larger in size. I think the legs were longer and the rest was the same, except for the 3/16" launch rod. The asbestos, if present, was a good idea. The blast deflector did not cover the masonite, so even the smaller engines would destroy it in a few launches. The LIA-77 I have does not have the asbestos pad.
The shipping weight was one pound more, 4 pounds for the LIA-100 vs 3 pounds for the LIA-77. I had plans for the LIA-100, but I cannot find them now.

I would think even the asbestos would get blown away by the blast. I was tired of having Estes blast deflectors gunk and rust up, so I decided to paint a few with Hobbypoxy paint. Of course, the first launch simply blew a chunk of paint off! The second launch got under the paint layer and blew even more off. I bought a roll of asbestos paper, intending to glue it to blast deflectors, and to our club's rack launcher, but never did anything with it.

The asbestos pad on my LIA-50 is the cause of my medical problems 48 years later - at least that is what my lawyer wants me to claim
