Maybe first I want to get this one done and tested. Then if I do make a run it would most likely be a very limited run with a price to match the work that would have to go into one.

update to day is I screwed up. I bought some PEG plastic to use as the handle nice and clear easy to machine good stuff kinda. first mistake was I drilled one of the holes too deep so thats no good but since I had the holes I wanted to make sure the other components would work. when I first put the main guide rod in it slid really nice but after "cycling" it i started noticing it was starting to stick. Now I have not used the PEG plastic before so I thought that maybe the grease I was using was causing a reaction I cleaned it out really good with some soap and water only to find that its not the grease but the ID of the guide rod hole was already starting to wear

So back to the drawing board for the handle material. I might have to go for the old stand buy of delrin but I bought some acrylic to try also.

So it was a slow day at work and I was looking at my design and came up with something better

less parts less bulk easier to machine. The original design sill had all the parts of a standard cocker a lpr a 3 way all as different parts but I realized their is no need to have a transfer tube going to a distinct 3 way I could just use the guide rod as the 3 way core and remove the need for 2 parts. Also with that out of the way I was able to put the return spring back into the upper tube so their will also be less threading.

PTFE might be another material to use for the pump handle.

You could also try over boring and a press fit sleeve of something more durable. Or even linear bearings if you want to get fancy

Well I did some more rotary table work today. and took some parts to make a conceptual mock up to help see what its going to look like.

I the handle is close but needs some cleanup in the gcode to make it work better.

This is going to be pretty epic. I wonder if psp would be ok with this for pump tourneys.

Demondestroyer · 01-12-2013, 01:40 AM

probably not seeing as you can't use pneumatic pumps at the moment, or mq pumps as far as i know.

Ahh I didn't know that. I'm just now getting into pump

When I played at Galveston last year a pump was anything you had to pump to make it shoot, but it may have changed.

weekend update

Dang man, youre setting the bar pretty high for the rest of us tinkerers!

What kind of machines are you running to make your parts?

nerve2030 · 01-14-2013, 09:19 AM

And Novakon NM - 145 cnc mill (4 axis) and a Birmingham 1340 lathe for the machines. On the software end I am running solid works 13 cad and hsm express for cam and using g wizard for recommend speeds and feed.

I have no idea what any of that means and it's wonderful

nerve2030 · 01-14-2013, 06:53 PM

This is my lathe (on a cleaner day)

Mill (also on a clean day) 4 axis not setup.

theblindchicken · 01-14-2013, 07:30 PM

Got some nice machines there!

Really diggin your air lines.

Fantastic use of a shower curtain as well!

Sub'd for the design. Can't wait to see how it turns out.

**Lurker27** · 01-14-2013, 07:59 PM

Fantastic work!

inmylife2415 · 01-14-2013, 08:10 PM

A shooting vid would be awesome when you're finished man. Great work tho!
