    Jul 27, 2006, 3:37 PM - The two knobs on the back of the helmet vent #1

    Anyone know what they are? are they a "found" item, or does someone have some casted up?


    I have something similar I whipped up, but they are a bit too large.

    They look like the "knurled" screw covers on the old time computer cases to me...

    I found something that looks close. I went to Lowes in the electrical section and bought some lamp sockets. The bakelite switches looked a lot like those parts in the helmet keyholes.

    Evan4218 has my helmet and those parts. PM him and see if he'll post a pic of them in the keyholes on my helmet.

    I'm also trying to source those parts... Or something close....

    Ripcode,

    thanks for the lead! - will have to swing by and see what I can find.

    These are the what you are talking about. They are a special type of wire nut if I am not mistaken. Sadly the wire nuts at your local home depot are too large. (As were the ones that RIP sent me for his helmet) So I am casting some. I will post when I have them done.

    Wire nut? Has that been confirmed?

    You found something better than the parts I sent you? These I have to see!

    I was thinking something along the same lines...the post like screw thing that you use to screw in a monitor cable or a scsi cable to the back of the computer.

    so whatever they are are the glued onto the calculator circuit board?

    Well, I went to Wally World and found light sockets that had the "bakelite" type switches on. (ripcode idea)

    About $2.67 USD.

    Snapped them off, put a little JB to make the dome top, (they had a flat top with a little concave surface) and tonight I will paint them up.

    They have the same length and width from what I can see on the pics, and with the dome, they are pretty close to looking like the prop knobs.


    I will be gluing mine straight to the circuit board with CA probably.

    All in all, they look good enough for my purposes!

    Thanks for the info guys!

    I thought perhaps they were wire nuts, but most nuts are flaired at the bottom, these are not.... Plot thickens lol

    (will post pics tonight)

    How I had mine originally attached:

    Drill a tiny hole into the part (The hole is the size of a paperclip). Drill that same size hole into the circuit board where the part is going.

    Use CA to glue a length of paper clip into the part. Then glue the other end of the paper clip into the circuit board. This gave me a way to control how high the part sat off the circuit board and you could easily bend the part to get the correct looking angle.

    However... since Evan4218 has a hold of my helmet... this method may change...

    I failed to mention that,

    I always pin anything like this with clipped off nails/paperclips and drill holes,

    stuff is less prone to snap off like that.


    Works really good on resin model kits of people, I've dropped them, and where I had it pinned, it survived.

    However, unpinned items went spinning off into the carpet, never to be seen again....

    Well, with the lead from Ripcode, I went to wally world and picked up two GE lamp sockets (52877) for $2.76 a piece.

    I ripped them out of the assembly:



    I added a few drops of JB weld to fill in the top, after it cured, I sanded it to the shape I wanted.

    Painted them up with red spray paint, then using dry brushing, put on the silver/chrome highlights.

    I then cut them a little pass the ridges, and added "pins" to them.

    Drilled two holes in the circuit board assembly, and used CA to hold them in place.

    I made the holes angled to the prop angles - makes it easier to mount.

    and this is what I came up with:





    I think they came out pretty darn close to the real thing!


    thanks for the help Ripcode - would of never thought to look at lamp assemblies for this.

    Sweet! They look great! I knew they would!

    Evan4218 isn't using the ones I sent him... I gotta see what he is cooking up! (And he's making me wait until Sunday! )
