For robs5230, TX V LGV pistons.

[T 20]

Further to our PMs, Rob.

I actually had a TX (MK3)and an LGV piston on my kitchen table. :-

Overall length of TX piston = 160mm, body length to bearing flange = 115mm.

Overall length of LGV piston = 180mm, body length to bearing flange = 130mm.

So if you add 15mm to the length by lengthening the seal arbor and using a 5mm longer rod a TX piston should do you.


All the best Mick

You’re a star mick
Thanks

No problem, Rob.

Measurements aren't 100%, but they give a general idea.

sounds like what I stuck in my '80

Given me plenty to think about Mick

I can buy a new LGV piston, so was looking at whether I can make the cost less by using a TX piston
Might just be better buying the LGV piston

Cheers

I suppose the genuine piston could work out cheaper than buying a TX piston, custom latch rod and custom arbor, Rob.

£115 for the OE piston, so by the time I've bought a TX one (likely easier to get hold of used) , then modified it, it will be close anyway

£115 --- Jesus. I'd have a word with NickG before pulling the trigger on that one, Rob.

Mine came out of a skip at the back of the importers warehouse.

Guess the options are limited now the spares are a bit thin on the ground

I'll have a crack at the Century as is, first
I may be able to get it ok
Always got on well with the 80 in .177

Luckily I still have a couple

[robs5230]

Had the Century apart and back together, half a dozen times now, with a few slightly different setups and ended up with a really nice shot cycle.

For the minute, I'm going to see how this shoots, before I decide what else to do.
I'm really surprised how little recoil there is

Happy with the trigger so far, but I zero from a rest, which for some reason, makes me very aware of triggers, but this one does feel very good, with a light first stage and a crisp break on the second stage. Definitely better than most Rekord settings, I've encountered on out of the box rifles.

In the earlier days of the LGV and Century being available, Bill from Solware brought a few along to a Boinger Bash for us to try and the Century didn't disappoint. 30mm guns, as you've experienced (and there will be many, many very nicely set-up 30mm '35s and 80s out there) can shoot fantastically well.

[TonyL]

P.S....I'm not sure if anyone has tried it yet (especially when the LGV pistons were readily available, making 25mm conversions easier), but I wonder how the Century might respond to a stroke reduction? Especially if it were done via nose extension, making it easily reversible, if later required?

Slightly faded memory here but one thing to bear in mind with the LGV piston is I recall there are some soft ones about. They gall awfully as a result where the cocking arm engages, a pal had a s/h rifle that was so bad he replaced the piston. Suspect it would have been a batch heat treatment thing and they have fixed it now for the princely sum they require for the new part!

Hi Dave
Thanks for that, I'll bear that in mind
