Gamma Progression ST II

[Alex13]

I just purchased a used Gamma Progression ST II for $680, probably overpaid. It appears to be in good shape. Seller said only strung a handful rackets, which I don't think is true. Anyway, I'll be cleaning it this weekend. I noticed that little rubber (or maybe silicone) o-ring shaped seals on the clamp stems are torn. Does anyone know where to get replacements?

Also, any general advice on maintenance and cleaning an used 2nd hand stringer.

Thanks in advance!

Call Gamma Sports for replacement parts or maybe @Gamma Tech will respond here. Other than that you could pick up some rubber o rings at Home Deport.

Thanks. I’ll swing by HD tonight. I think it is 12mm size ring

Correct, the I.D. is 12mm (since Gamma string clamps have 12mm posts).

Yes.
Sent you a PM.

Thank you all! Also, one of the rubber feet (tabletop model) is missing half the rubber with inner bolt exposed. Does anyone know where replacements are sold? @Gamma Tech

Rubber stuff I'd try McMaster-Carr.

Edit: While you are there getting o-rings and rubber feet pick up a bag of electrical grommets They make good vibration dampeners.

Actually, I have part numbers of stuff I've used. I've used both 9600k46 and 9600k21 as dampeners and 9752k116 as o-rings.

If one is bad I’d replace all 4 Gamma Sports is your best bet.

What’s the part number for rubber feet?

I use #64 at Walley World. They make good dampeners. LOL

Actually it’s all a matter of preference some like O rings, some rubber bands, some like worms, etc…

I've never needed them but you would probably find them here: https://www.mcmaster.com/products/bumper-cushions/bumpers~/

McMaster has so much stuff and I think all stringers should familiarize themselves with the site.

Meh, I don't think you overpaid at $680 if that's all that's needed, a couple of o-rings and a rubber foot, if the rest of the machine/turntable and clamps are in good order...it's a $1K/$1100 machine.

Looking for replacements at a hardware store is probably your cheapest bet, since i would have to ship them to you. The below commentors are correct that you need a 12mm inner diameter. If you have trouble finding some i do have extras in my parts stock.

@Gamma Tech - I emailed a week ago and used LiveChat option twice. On Wednesday I was told because of thanksgiving it takes a bit longer, I’m still waiting for response. Is there a number to call?

I think you'll be happy, I've had my Progression STII for a number of years now, no complaints.
