Back in the 80s, I had an RO72 pistol with and aluminium cylinder tube, to hone the inside, I simply used gaffer tape to fix a piece of old t shirt to a wooden dowel, then put it in the dril and used Solvol Autosol metal polish, the smoother you get the tube, the easier the piston washer will slide.. and it costs very little PS, make sure you wrap the cloth around the rod in the correct direction, so that it doesn't unravel itself whilst spinning!
Hey up Geoff, the Diana 460 that I picked up of you on Saturday is brilliant mate , the more pellets I put through it the smaller the groups are getting, cheers Geoff 👍
Years back when I tuned my HW35 .. I used a broken 12 bore cleaning rod , with a reasonable grade of wire wool and metal polish ... so far back can't remember what polish. Chrome or something... I attached the rod to an electric drill and just went for it!! .. I remember my dad laughing at what I was doing whilst ramming it backwards and forwards as he walked into the garage 😂.. I said I'm honing the piston cylinder .. he raised an eyebrow and smiling .. left me to it ... well .. all I can say is I regularly took rabbits out at 60 yards and even beyond!! Now before you comment on you shouldn't shoot beyond 40 max.. with sub 12 ... I used to stalk and hunt wide open meadows adjacent to woods .. and most times 40 to 60 was as close you got , so rifle was zeroed for 40 yard . I'm talking way back when only gunsmiths had chronos .. I doubt my 35 was much more than 11.4 ftp but boy oh boy did it shoot smooth and accurate, yes honing tools can be made or thought out OK.
I've heard this recently from a Australian friend living in the Uk, how Liberal Australia has become, to think just over thirty years ago i was out there and considering going pig hunting with a New Zealand guy i met with a English 303 which he could of bought 😂
Very good idea to use the draught excluder, I've never thought about that before. Works like a cylinder glaze buster, I suppose using a drill on a slow speed and going up and down would work best.
Most suggest never use wet&dry on the inside of the cylinder, the reason being, make it to smooth and the grease off piston has nothing to hold on too, been told this many times , with respect, what is your take on this smooth.
Hi Geoff excellent vid I'm looking at polishing the comp tube on my tx200 would this method work and what grade paper would you recommend I start with and them finish with also would you recommend some sort of metal polish ? Many thanks in advance
Hi Philip. I'll be honest, I tend to aim for more of a honed or cross lapped surface inside compression tubes, to allow tiny surface scratches for holding the silicone lubricant. A finishing pass with abrasive around 600 grit is ideal.
Hi Buddy. The aim is a honed/clean cylinder, no intention to coarsely remove material with rough abrasive. Most of the wobble is from the bar, not the head.
No need for a hammer during the design phase 😂 And in the triggers I've seen for springers it's just the seers and the catch, no hammer in sight. Hamers are more often found in firearms and PCP / CO2 systems where the hammer hits on a valve stem for a short release of gas.

Thanks Scott. Always great to hear good feedback.

Excellent, this is by fare the best way I have seen. Best regards from Germany
Great idea and video explanation. Thankmyou
Cheers Geoff.
That's a great tip. Many thanks, Geoff.
What a legend fantastic 👍
Cant believe you didn't make one earlier. Blue Peter lol
Miss my air rifle in UK. they are illegal here in west Australia without a full firearms license up to 14 years in prison

Hi Geoff what’s the best way to size a piston seal?
Would you use this to hone a hw35 cylinder? Many thanks
Very good idea to use the draught excluder, I've never thought about that before. Works like a cylinder glaze buster, I suppose using a drill on a slow speed and going up and down would work best.
Fkin hilarious. But seriously a great tip on making a polisher. I have one but never thought of sticky backed foam. Top video bro.

The 240 grit sandpaper he uses won't give a smooth finish, so should be fine. I used a brake cylinder honing tool in my gun.
thanks for sharing! what does honing the cylinder achieve?
It’s to debut any imperfections and keep it nice and slick for the piston to move smoothly.

@@lsduk thx geoff for the advice much appreciated as always
Phill
Just dont use silicone grease with metal on metal parts @@phillipward4862
Hi Geoff, excellent video. Will my 97K that you have get this polishing treatment? Call you tomorrow to confirm Cerakote colours mate. Philip Y.
I use a tool I've manufactured here for this, the video was just to help Folk out with a cheap & effective DIY version Buddy.
Funny bastard lol.
This honing rod is not very round. No issues with the wobble in getting a nice even hone?
Hi Buddy. The aim is a honed/clean cylinder, no intention to coarsely remove material with rough abrasive. Most of the wobble is from the bar, not the head.
@@lsduk do you have a tip for an improved 26mm piston seal? And maybe for a new barrel seal too?

@@redauwg911 interesting. But $25 shipping is killer.
@@FlexDRG yeah I got the spring and guides to go along with it
Can you design an air rifle system without a hammer?
No need for a hammer during the design phase 😂

est ben 6mn de vidéo juste pour ça ,,,,,, = tout ça pour ça ,,,,,,
Oui. Aviez-vous quelque chose de plus important à faire?
🙂😅👌👍👋🏻👋🏻👋🏻
