My Latest TX development

great consistency across those temps...

BTW What's wrong with a steel comp tube ?

[Born Again]

I've made many parts for musical instruments from G5 Titanium (Ti6Al4V). It's a light strong material, but perhaps equally important for airgun use, it's very easy to anodise. Once anodised it has a hard low-friction surface, the thickness of which can be accurately controlled by the voltage used, and can be added to at any time - it's doesn't have to be "baked in".

It's not as easy to machine as aluminium alloys, it requires sharp tooling and good control of tool temperature either through plentiful coolant or reduced speeds and feeds.

It is a poor conductor of heat.

If piston sizes are coming down to 21mm or so, maybe this is now an affordable option.

nothing wrong with steel, I have a version with ally piston and comp tube, my theory being they both expand at the same rate , as does the material I am using for the piston ring, but the real bonus is the low friction teflon in the surface finish.

Excellent work as always mate. I’ll look forward to our shoot out.

Your gun on the day will be one of these be nice to get some feedback

I see the logic.. can't argue

This is going to be a very interesting thread, what formats are you considering Nick ?

Sorry don't understand what you mean by that?

This available for the airarms pro-sport?

very nice bud

A most enjoyable few hours out this morning with my very clever mate, Nick




The rifles shoot absolutely beautifully, seriously impressive. Nick has invested years into the development of this particular tune and it clearly shows. Targets at maximum ranges were toppled with confidence and had we been keeping count (and if the wind had behaved itself ), then I think we would have come away with some very impressive scores.
One of my TX’s will soon be with Nick for an upgrade

Huge thanks again for today, Nick - really enjoyed myself and left suitably impressed.

nice. PS Your ABT fell off
