SILICONE OIL?

[rogb]

Hi and welcome to the BBS

I spoke to Steve on Monday about this specific matter and he only recommnded a slight smear of moly around the piston seal. Maybe these are very old instructions, but silicon is now thought to be best avoided.

Could you quote them exactly please?

Yes it is a new TX200 mk 3 instructions no 11 A light coat of silicone on the inside of the piston will aid fitting.
I now don't use silicone but have done in the past on the piston seals so have I done harm to my guns? So far there is no evidence of this and as I say there is a lot of guns out there that have been professionally lubed in the same way that I described.
It looks like if you mix a drop of silicon with moly its OK? I will try some experiments. Barry

I have seen the internals of several guns that were totally knackered by silicone oil, and it's not a pretty sight.

I've never had a TX apart but, looking at the line drawings on Chambers, I gain the impression that the piston body does not come into contact with the compression cylinder. If that's so, silicone would do no damage - it's metal to metal bearing surfaces where it should never be used.

I'd use a dab of moly grease, though, just to be on the safe side, and I wouldn't mix moly grease and silicone.

Isnt there a difference between silicoN and siliconE?

I dont know what it is but I seem to recall a thread where the difference and applications were explained.

I don't understand why you would want to use it. Bengarzy has thoroughly warned us of the consequences of its use in pneumatics - that's good enough for me. As for spring guns, there's sufficient doubt been cast on its suitability by almost everybody who has ever 'dabbled' with spring gun tuning, and there are many other suitable products to use. Have you bought a lifetime's supply of the stuff? I can think of one application for it, the 'o' rings and joints of a garden hose. Regards ... Geek

I think the confusion comes from products like Abbey SM50, that say they are safe to use on piston seals. I was confused too, but I spoke to Steve Pope, and as far as he is concerned, for V-Glide products, like my HW80, not necessarily DIY tuning kits, there is no need or advantage in using Dri Slide or SM50. Just the right grade of moly grease on the piston seal, tiny amount, and some on the spring, other synthetic to metal or metal to metal lube points are taken care of with a special "anti-scuffing" grease. The spring is coated with a special "anti-fling" spray grease.

This is what I will be doing to my HW80, cos it's special

goes into song... "so f#####g special..., you're a creep..."

Have you seen the price of Rocol "anti-scuffing" compound? It is ... ... shocking! Regards ... Geek

My understanding is that silicon is the raw material and silicone is a product containing it.

Could be wrong, though.

Moly grease, and moly-g paste is the stuff you need. And not too expensive.
