The "polish one" chrono-R2, works a treat.

I suggest its the gun....unless ran completely dry ...and i do mean scrubbed out with degreasant within an inch of its life ....it micro diesels like a bigun...

tried mine at the club today and it shot really well over 10 metres free hand but did get the odd smoker. gonna strip, clean and polish tomorrow. just find it a little hard with the recoil and the conbro

New breech seal git me to 4.9 ftlbs.
Finally stripped it.
Got a feeling someone’s been there before as the two 5p coins gave it away as power washers and tonnes of lube. Polished piston with lightning holes in it. Will add photos

5p's? Yep, that's an aftermarket option. They were fitted with 10c coins from the factory.

the 5 ps a collection of loose change which would actually add to the already erratic beast.

How do you attach a combro to an HW45?

With equal quantities of care and luck, I reckon.

I have been holding mind with my hand round the muzzle. Seems to work fine now

That should be ok, it was when I was testing power at 10m that I tended to clip the edge occasionally.

I tried that and never clipped it once. Then again never got a reading

Well I’ve stripped and polished the internals. Got some Delrin coming as want to play around with guides and top hats.
Question for the experts out there the piston seal was a very tight fit and took a lot of effort to move the piston in the compression chamber. How much restistance should I be looking to move the piston in the working area?

[clarky]

Back it off....machine a 7 degree angle on the compound slide from the front face to the piston interface.
leaving a fine edge which seals...go sliding fit....it will soon seal up as the angle will bed in and self adjust for wear ...upto a point.
Just dont expect too much from the top heavy bugger....it is what it is...
5 ftlbs fairly accurate with no piston weight....
Any top hat weighting will add power ...gram per gram....but jump will be added gram by gram too.
Dont introduce lube ....run it dry until it wears out....it diesels on anything more than pure air....and im talking not the air in London....
