Anyone hone aluminum before? Wondering what fluid I should use. Oil or water. Hopefully the anodizing isn't too hard.

I use WD40 when machining aluminum and seems to work ok.

If your thinking a hone will replace lathe machining of the air tube to fit a regulator ... IT WON'T
as too honing aluminum, kerosene works very well and likely as stated WD-40 would as well.

Huma recommends it as a method to remove scratches. See Air Arms S4/5xx  fitting instructions made by Mr. Coverleaf of the Airgunforum (Excelent manual) on their site.

I really doubt I could remove .002"+, but If I can get the scratched out, they'll make one to fit.

[MonsterMaxx]

Any interest?

yes

[BSJ]

Good news. Huma has come up with a design the fits partiality into that rear cap. No need to hone!

I measure my cap to have a cavity of 0.595" in diameter and 0.619" deep.

Anyone want to verify that their cap is the same?

I received the Huma Regulator after work yesterday and just now I received a email from Huma about the fit problem and ask for exact dimensions of the tube and cap for their records. This has to be a great company to respond so fast to resolve this problem. Now I have to make time to do Donny's mods and try to install the regulator.

I also got that email too.  Huma does indeed react quickly it would seem.  I'm still waiting on my reg before I take the cylinder apart to measure the tolerances on mine.  Below are some bad pictures of what I did to my gun to remove the factory reg parts:

Donny, thanks looks great, you did a great job and I'm sure that it will work.

 Well I ordered 3 of those humas before the hurricane haven't  heard anything yet and now seems they have a problem with fit, jeez, have already ordered a replacement reg for the pistol and it was worse than what I had,  that's not counting replaceing all the washers before. can keep them under 700 fps and the factory works good but seems anything over 700 fps and they get erratic, you might get a good string today but tomorrow is another storey. .

Speaking of replacement parts. Say I want a tube and two end caps... Who's selling parts for the PP700?

[TleVta]

schultz posted the SPA contact info in another thread. The shipping is a bit pricey, but they're available if you know the part numbers.

There he is!  I was wondering when you'd get back onto this pistol post   If it makes you feel any better, I think my regulator from Huma is lost in transit.  My tracking number shows it was sent on the 12th, but no information after that...  Hopefully, we'll get some regulators one of these days. 

Donny, thanks looks great, you did a great job and I'm sure that it will work.

Thanks!  The part that really makes it work is the little PEEK plug I made, and it is super simple.  The gun is holding air just fine without the "reg" guts, so I know it should work great when I get the Huma installed I played with it a little more, and got a decent 15 shot "power string" out of it(minus reg).  That was 15 shots using the CPUM 10.5 grain pellets, and it averaged 826fps with a 36fps spread.  The lowest shot was 790fps, and all but the first and last shots were in the 800s.  I think it will work very well with the Huma.

I believe it was wimpanzee that made the post, fwiw.

I will measure mine, when my reg shows up.  I curious to see pictures of that new design!

[TleVta]

I was e-mailing Huma this morning about their redo after they contacted me. Would be great if they just made an aircap that replaced the stocker--and have the reg built into it.

[Rallyshark]

What would be even better, is if they made a whole new piece that fits into the receiver too!  Of course, it wouldn't be nearly as "affordable" then  

[BSJ]

It's got a cross section like a + sign. Thin-fat-thin. Instead of just thin-fat.

[Rocker1]

Well still no news on the 3 huma reg I ordered but do see where this link is no good anymore, maybe they are holding them until they get the bugs out.

I emailed Huub, and he said he had already sent new measurements to the CNC department for a change. Mine is in customs apparently, according to what Huub was able to determine. I gotta say, they respond quickly to the emails, so that is good.

Did you get a NL tracking number? If so, you can enter it into our USPS site and get updates.

They sent mine registered mail, so I had to sign for it...
