Fresh off the mill.
Big relief, I'm now certain I can do these on my VMC. Everything is looking good just need to fine tune a few of the tool paths and add a few to clean up some burrs. Hopefully I can get that done tomorrow, we'll see. For now I'm pretty stoked, in a few days we can move on to the Deflator machining.
Home made slug body !
You going to be selling them separately ?

Progress means I'm that much closer to a new body

Someone may have already asked, but is there any reason this can't be pump milled?
Er wait, foolish question. It's unibody, so of course it won't be pump millable, right?
As far as difficulty goes this is less difficult than other stuff I've done. My biggest hang up initially was finding tooling to make it on a VMC rather than a lathe.this is your first public body from scratch.
I'm holding off on showing the "hidden details" until I have a chance to test it and only because I don't want to argue the idea at this point. (lol) If it doesn't work, a few hours of re-design and I can switch to a standard uni-body, easy-cheesy-japaneesy.
Yeah I am liking that square body, put a square cram and jam, cut the bottom of frame to make it more compact and you have a damn nice sexy pistol.
Nicely done! Looking forward for the hidden details.
If a pump-able deflator (har har) comes to fruition, I'd probably be on board for that though. Might need to work with knm to adapt the snap-on stock class adapter for the deflator if that happens.
Making lots of progress, been tweaking both the Deflator design and the machining on the slug body. I've been less than happy with the quality of machining on the internals so I'm currently on my 3rd attempt to retool this project. Most of my third tool order is here as of today but I dont expect everything to arrive until Thursday or Friday of this week. I think I got it right this time, cross your fingers!
While waiting on tooling I've been dialing in the design and machining on The Deflator. I finished this body earlier today, I see at least two small design changes I think is necessary. First I want to taper the back (backwards) top and bottom of the valve, it looks a little wide from the back. Also, I'm not sold on the two horizontal lines on the side. To me it looks a little off, so I have a design idea that may fix it. Also the top two edges will have a heavier radius on the final machining.
This is not the feed tube we will be using, I just added that to complete the look for the pictures.
This body is not ready for testing, I just pulled it out of the recycling bin to test my machining programs for The Deflator. I'm not going to bother testing until I get the final slug body machining dialed in where I want it. This body will go in the trash as soon as I machine another.
This puts the size into perspective. At this point it looks like the Deflator will weigh a little less than the MM2k.

I like the 2 horizontal lines on the sides. They add a little and kind of make the gun look longer.
I like them too, it just doesn't quite look right to me. I'm not going to remove them it just needs tweaked so it flows better top to bottom.
Maybe perhaps if you add a third horizontal line, or break them up into angled bars, similar to the vertical ones behind them. Will the final design still be so sharp at the front, or is there material there to shave off?
This is basically it. A heavier radius along the top will shorten the "sharp edge length" some. If I round the front heavily it will turn it into a fish mouth. I used the lower part of the body to transition the round FG to the body. I may add a 45* chamfer to the edge but it will be minimal. This was the look I was going for so I really don't what to make big changes to it.Will the final design still be so sharp at the front, or is there material there to shave off?
looking good luke
keep up the good work
I know how it goes when operations do not cooperate, very frustrating at times
Polarstar Engineering and Machine
that ID work sounds like a huge PITA
esspecially if you are limited to a VMC
but looks like you are getting there
Have you tried gun drills for the bore? there not cheap but hold a great tolerance
