Turned a few, they work well.

What is the advantage of these?.

[Ca_Varminter]

I  am looking for a better seal... with less Lock-up pressure....
I did try this long ago.. but with Delrin(Acetal)
Not as durable as PEEK... It didn't hold up well....
So PEEK has been used many years by the Tuners over here...
Never got around to order some stock to try....
Well these guys on our site MADE me TRY!!!!!!

Time to pressurize the UL_Ti_Mate Rapid...
Let's see how it takes to 70 fpe...

if any one is making these to sell I would like 3 in .177  please guys.

[Squinty]

Thought about making one in 177 but there is only 0.8mm in the walls.
Less if sleeving the tip.
I made my .22 inners 3mm instead of 1/8- gains 0.1mm

[flyfisher]

ah okay mate, thanks for the answer.

Anyone ever investigated cutting a groove in the end of the outer probe and sealing with an o ring. (70 or 90 shore for example)
That way, any leaks that appear over time, just change the o ring?
I am not in any way mechanically minded....my unfinished kit car can attest to that, but seems an inexpensive way to solve the leaking issue when it arises.

Kind Regards,
Rhys

Its been done

Bucketboy machined o-ring grooves in metal probes  a few years ago.
Haven't got round to it myself although I have tried o-rings to overcome fine adjustment on an early R7 bolt.

However I do prefer the firmer lockdown with Belvilles, lost count of the times the cocking handle popped out of the gate bumping around the fields at night when I used an o-ring.

[Squinty]

there you go..  just a quick trial on a bent outer.
Not a full groove in the face of the outer, imo it would need a 1mm o-ring supported on both sides.
O-ring sits on the inner under the spring, compresses into a radius.

I think he meant a groove & O ring where the outer probe seals on the barrel breach, not to seal the inner probe.
