For anyone who hasn't seen the results of the destructive testing, post #1342 is a good place to start reading... the second (refined rig) test is around #1413.

The 60s took a real hit last August. An unjustified hit... GTA (with a little luck, right there at the end) saw this through.

SA's commitment to further support and development of this design (Fusion and 60C) will continue unabated. The only visible difference, around here, may be a small smile!

Well guys... looks like the saga of the exploding FDPCP is over. http://www.gatewaytoairguns.org/GTA/index.php?topic=96148.new;topicseen#new

The tube was found, measured, and found to be way below min allowable OD. Not surprising, given the results of my tests... and (like my tests) a vindication of the design.

No surprise there! It was obvious from several posted pictures of other MM manufactured tubes that the threads were not only undersize but of abysmal quality.
A case of too much drama and not enough common sense.

RMM's LW barrel and .25 Evanix mag showed today... I'm tickled pink about this:

Compared to the MRod .25 mag (this one is Lloyd's .30 conversion), the distance between the bore's center and the bottom of the mag is much less on the Evanix. This means the Evanix won't require as deep a cut as the MRod... so, it won't require the extra work of making the valve block into a cover for the bottom of the mag slot. The mags are more expensive, but the work required to nicely mount the big MRod makes that conversion significantly more expensive. It's a win/win.

The mag is nicely made, operates crisply. All the Evanix mags have that same dimension in common, so there will be no need to cut a different slot for each caliber. FWIW, I figured out how to mount Evanix's longer mag, too. The method used will be the "mag/valve forward" set up discussed during the stroking experiments. The room to stroke this set up is beyond all possible need.

Also, I got something in that will eventually be mauled with every claw SA has... can you guess what it is?

Thanks, Lloyd...

Cool!.... what calibers does the Evanix mag come in.... that are interchangeable?....

Judging by the pics, the .731" mags are available from .177 to .357. https://www.pyramydair.com/search-results-ext?keyword=evanix+magazine&sid=1375A617A415&N=0&Ntk=primary&q=evanix+magazine&cx=002970863286801882398:jlcminxfwdw&cof=FORID:11;NB:1&saSearch

If there are any Evanix aficionados reading, I would appreciate conformation of this... please.

The 22 cal is shorter than the 357 and there is rumor that there are two 357 variants with differing depths.

RSII 357 = .477" ( circa 2014)
RSII 22 = .388"

Both the 22 and 357 have the same bore to detent dimensions IIRC.

Thanks, Tom.

This is gonna require some homework. To get a standard fitment for as many calibers as possible, I may have to sleeve the compatible big bore mags, like you did Ron's (nice job, BTW).

Guys, no promises until I can get a decent herd of these mags assembled here.

Here's some good news for anyone contemplating putting a LW .630 OD barrel into a 60... It *just* fits without turning the OD down. Makes a nice looking Bull Barrel... saves a bunch of shop time.

This gun has been dubbed "BBE"...

Best. Bobcat. Ever.

NICE!....

stalwart · « **Reply #1590 on:** July 14, 2016, 02:38:32 AM »

Thanks!

We have an interesting situation here. Mike wants to bond the barrel (hence BBE)... so it won't have o-rings... so, we can put in a transfer slot up to 9.25mm long (longer if I tilt the receiver in the mill to finish the front of the cut. 10... 11?).

How much is too much?

I haven't kept up with this thread/project for at least a couple of months.
Glad to see this project has really got some new life back in it.
The progress is looking GREAT Eric !

Thanks, Ron!

Yeah, things are still a bit nuts here, and the DD thing is adding to that... But... it won't be that way much longer. I found good help (whew!), and as soon as he has a few processes down pat, things will get MUCH faster. SA is growing faster, and in more different directions than I had planned... so this has to happen.

As to the DDs... We will be ready to take orders in a week or so. The first up will be what I call the "Classics"... the kit Lloyd has been selling all along. These are in (very) limited supply, and will be replaced by the new (reg ready) kits when stock is depleted. See my impending announcement for lead times and prices.

stalwart · « **Reply #1593 on:** July 26, 2016, 01:15:28 AM »

Also... what the heck... Anyone who contributed to the July raffle will be given a $10 discount on a DD kit if purchased within 6 months. Be sure to remind me, with your screen name and the numbers you picked... and I'll buy a number back.

stalwart · « **Reply #1594 on:** August 23, 2016, 05:21:34 PM »

I just finished my first cerokote job...

If the directions are followed precisely (prep, prep, and more prep), it works well and looks great!

I will be adding this to the coatings SA offers.

Should be a good durable option.

It has a good rep for that.

It's a joy to shoot. Much like a metallic base coat, you don't hose it on.

The project it looking great. I havent been keeping up on it like i wanted but i am glad to see how far it has come. Maybe if i return the Maximus i will try to pick one up.

StevenG · « **Reply #1598 on:** August 25, 2016, 08:45:43 AM »

Since Stalwart is now doing Disco Doubles, I bet he could do a lot for a Maximus as well.

I bet he could. But I have been just having so many problems with my Maximus. I had to send the first one back because it had so many defects. This one is very inaccurate. 5 inch groups at 10 yards. At this point I don't know if I should just see if I can try to get it to be more accurate with a fluff and buff or just return it and forget the whole thing.
