The Siren Board

So thirteen years, huh.. I think that's a restoration hiatus only exceeded by Jerry's gas-powered MD. Cool to see a familiar face still pop in these days.

Oh yeah, lost or misplaced bolts can totally be one's worst nightmare!

Thankfully nothing is lost other than the knowledge of where it all goes. I think I figured out 90% of it now by simple logic and trial and error.

I DO need help replacing this though if anyone knows where I can find one.

Is that a part that can be 3D printed and do what it's supposed to? I'd print that in ABS and treat it with an acetone vapor bath. Otherwise, I think a company like SendCutSend could machine a new one for you. Are you able to make it in CAD?

That's a lock washer for a bearing, to be exact a W-02 sized one. You can get them off of EvilBay for a couple of dollars.

Update.

I cleaned up the chopper, prepped for some corrosion control. I have lock washers on order. I was able to recover the projector and the control box from the museum... Sadly it seems like the rotator was misplaced, potentially scrapped... So now I need to see if I can find a replacement, or find the exact specs to build a new one. Thankfully I have access to a full machine shop, however, I would need to have some sort of reference to go off of to rebuild it.

Oh my gosh - that was a LITTLE lock washer? Maybe next time the OP should have a coin next to it in the picture or something - LOL! It looked bigger to me - I was thinking maybe 3 inches in diameter

I thought it was something like a wheel bearing lock washer with a key and tabs like the ones on the axles of my army truck.

Wait your control box and projector was at a museum?!
Edit: where is the blower?

Yeah, at the time I picked it up I was living in an apartment with my mom. Didn't have the space, or know how to work on it. Originally I worked out a deal that I could use one of the restoration hangers at the Air and Space Museum if I agreed to donate it, dropped off the rotator, control box and projector with them. I kept the chopper / chopper housing at my house for restoration... Kinda lost touch years later.

I was 20 when I picked this thing up... Wasn't fully thinking things through. In hindsight I should have reassembled the rotator and painted it yellow, it would have likely been saved if I did. That's literally how the control box and projector were saved, because people knew what they were merely from color alone...
