Wondering what people have been using for blast deflectors for K/L/M impulse pads? I've heard of people using grinding disks, how's that working out? Stainless steel is expensive.
It's no harrow/plow disc, but I noticed an orphaned 14" hi-hat top in the shop today. Got a couple of cracks, and no matching bottom!

I wonder what it'll sound like...
I like it. How about the '55 Buick Roadmaster bumper bullets for nose cones?1945 Buick Roadmaster Hubcap
those things probably weighed 35 lb a pieceI like it. How about the '55 Buick Roadmaster bumper bullets for nose cones?
Sure. They helped that car achieve a curb weight approaching that of an M1 tank. In fact, I think the M1 used Roadmaster bumper bullets for tips on artillery rounds.those things probably weighed 35 lb a piece
Yes, this is important! A motor with 100+lb of initial thrust puts a lot of force on a deflector attached to a pad...if you watch enough launch videos you can see the pads bending and jumping when the deflectors are attached to the structure. You do not want this force transmitted to move the launch rail or you can get a lot of whip, especially with spider type pads that are very springy. In the desert they can be on the ground...some tilt is helpful to prevent roasting the back end of the rockets.Like Steve said, concrete pavers on the ground. Blast deflectors attached to pads are a bad thing. I know that blast deflectors are required in many codes, but I know that some people remove blast deflectors attached to pads before they launch their rocket because they noticed that the rocket launches better without the blast deflector. Particularly blast deflectors that are angled and not a "V" design.
If you don't want to haul around a concrete paver, just leave it at the launch site. Chances are no one is going to take it. Sometimes, simple is better.
Put a hundred or so loose poprivets around that think and turn it into a sizzle cymbal. Only to be used with sparky motors!!!It's no harrow/plow disc, but I noticed an orphaned 14" hi-hat top in the shop today. Got a couple of cracks, and no matching bottom!
