I measured my old Centuri deflector, and made a flat pattern for it from SolidWorks. A buddy at work has sheet metal equipment at home, and he made a few for me...I didn't bother with the wooden block and separate clips. He used whatever gage of metal that was handy, which was thicker than the original.

edit: that "large" deflector is NOT the larger Centuri deflector, it is a replacement for the Aerotech launcher, using a thicker gage of metal. sorry for any confusion. If somebody comes across the dimensions for the LIA-100 deflector, I will get a similar drawing posted.

No doubt, ceramic is superior w.r.t to heat tolerance, but, you gotta admit, it's heavier and more prone to breaking. Not sure if either of those is a deal killer, but I've heard of guys using clay tiles (ala roofing tiles), and I could see that being a klunky item to have in my range box.

As for using cheap galvanized shingles, you can do the same thing with a sheet of galvanized steel. I have a piece I cut using snips and can get umpteen blast deflectors out of it. And can use it for other stuff as well.

But those are all good suggestions for blast deflector materials.

I have several of these for sale. built and one unbuilt. I have 3 different sizes and believe them to be original. I also have some of the deflectors. If interested I can send pictures, I had these at NSL but know one seemed to know what they were.

I must have not wandered down to the right place to have seen them.....I would've known what they were

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

I SHOULD have said good idea for saving the pad, not for humans!

Wow, and here I thought my lawyer, Bombastic Bushkin, was just being nice when he gave me mine. It's not like he wasn't concerned about my welfare, though. He thoughtfully recommended I start smoking filtered cigarettes to keep a barrier between me and the asbestos.

That's really cool, Gus! That's an interesting way to pack the "hardware."

Around 73, I bought a Centuri launch outfit, sans rocket as I recall, at a garage sale. It came with that asbestos-topped wooden pad. I remember pinching off little bits of the strange fibrous stuff . . .

In the late 80s, I bought a partial box of those launch lead /deflector assemblies. They were high up on a shelf in the same hardware / variety store where I bought rockets as a little kid. There were three or four of them left in the black and orange box. I had plans to recreate pads with them, but I ended up liquidating them with much of my old rocket stuff when I moved west.

Anything with the word 'best' in the name like AsBESTos cannot be all bad.
Asbestos is a good product for the intended NEED. ANYTHING else should always be secondary.
Just like SmoKING, which has 'king' in the word....it must be partially good.

People are such safety/enviro mamby-pambys nowadays....No asbestos this, no DDT that, no Lead in fuel, get rid of all DECENT pesticides, lower VOC content in paint, gotta have a car safety seat for this, yadda yadda....
Makes me literally want to PUKE with the sissy/nanny state that has been created at an accelerated pace over the last 20 years.
Disgusting.

I will continue to use VOC laden paints and whatever else I darned well please no matter what any enviro-whackos (ALL environmentalists) think.
