Hey EM gang.... happy new year!
I bought a Jet Spin last November and this week, I set up the game and play a bit....tested the targets with my finger to check the points......
I have found out that scoring points from each roto target isn't right......I thought I would adjust the roto disc on shaft with set screws.......but nope, I was wrong..... I didn't look hard enough.....

Somebody repaired the roto target disc with a pop rivet gun.... all 15 targets have been removed (some broke off) and reattached in the wrong places.......OUCH!!

Now, I'm deciding..........to look for a whole roto disc on eBay/EM seeking parts thread.....OR
rebuild it myself with all new 15 brackets and brass tubular rivets from PBR?

I'll email Jimmy to see if available but first....
I need to know what it called? "Roto target leaf bracket"? and part #?
Large brass tubular rivet for Bakelite disc is 1/8" dia but not sure the length....small rivet for target face....3/32" dia? length? Probably they know the rivet sizes...
One steel plate (A-1826) to replace home made sheet metal....

If parts are available from PBR, then I'll rebuild the roto disc....but I need 3 target faces, one "300", one "400" and one "500"
I'll post it on EM seeking parts thread....Thanks.

Quoted from SirScott:

There was someone on Mr. Pinball

Thank you Sir!! I just emailed him!

Quoted from Cash_Riprock:

Just a thought...what if you bought the decal replacement set and put them accordingly to what the target scores. ?

Yeah but I'd like to keep my game in high quality condition! Thanks!

Quoted from kangourou:

put the metal card target A-18741 on each target, because the ball often goes between them !

Maybe.......Close Encounters of the Third Kind (solid state ) has one with same plastic target faces....I'll look for it.
Thanks Kangourou for the part numbers!!

Quoted from pinhead52:

I do have 2-3 leaf brackets I could spare

Thank you Ken!! Are these NOS? Can you hold them a bit for me? I emailed a guy from Mr. Pinball and waiting....

Quoted from yfz450:

Theo, I would also be interested in what Steve has.

I'll let you know soon....I think PBR is closed for xmas/new year....probably open on Monday
Cheers!
