What material are you using for the pump arm shaft?

ground stainless. not sure of the exact alloy. what mill you getting?

svdspecialist, I wouldn't say it's my life. It's just a hobby for me. Although a few months ago while I was still working part time and in school, I relied on it fairly heavily to help pay the bills.


Evil_racecocker, it's all about the bearing! if you use a crappy bearing you'll have a crappy feel to it. this particular bearing cost about $50, and uses high percision ground bearings. Combined with the percision ground shaft it should have a nice smooth feel to it.

sensored, yeah, i've done a few projects before, lol.

Leafy, there is only one body port in the mail body, that splits into two in the upper portion. but there really is no material to run the pump arms thru once it's milled.

the magnetic pump return isn't going to work. magnetic attraction/repulsion decreases exponentially with distance.

This is finally happening eh? Looks great so far and now I see why you were asking me if mine could be from a Merlin extrusion.

I'm getting a taig mill. I couldn't find anything even close to its quality in that price range. Is their little lathe any good?

I'm well aware of this. I'm not expecting it to fully close the breach, but keep the breech from staying open.

desertT1, yeah slowly it's happening. there needs to be more hours in a day!

ccluff2, good choice. That's what i'm running along with a Gecko G540 controller and Mach3. I have no idea about the lathe, but ask Strange, he just got one and has been putting it to good use so far.

To counter-act the magnets getting weaker with distance in my designs, I always have multiple magnets stacked along a guide that float on one axis, its like a spring, but smoother.

Just a thought to go with. You can't really much except plastics and aluminums at that point though.

[Leafy]

I had another thought for magnets. make a push away setup at the back of the stroke and a break away setup at the front. that way it pushes it back from the back and still holds the breach closed.

[cww516]

as long as there's something separating the magnets at the front, that should work nicely. otherwise things will stick.

ever crank the magnet return screw in too far on an eclipse-made frame? that's what i mean.

I've thought about doing this, and really there is nothing stopping me except my lazyness, lol.

Hey man I have access to several special order industrial catalogs and I was wondering if you could tell me what the specifications of that bearing are? Oh, and you do amazing work, I read a lot of your threads. Keep it up man!

[Pote]

subscribed, i want to see where this is going...

[FoidPoosening]

Very nice Cliff! And talk to KCSP (i think thats the acronym) customs, they've built some very sick double feed phantoms.

I remember one of their models had a two stage trigger.

Pull the trigger halfway, one barrel fires, the other have, the other barrel fires.

Or, pull it all the way at once and both fire.

Sick idea, doubles potential bps, work it in maybe?

[cs900]

that would be really easy to do with a double phantom, as each barrel has a seperate hammer. This has one hammer for both, so it's not really an option.

[new ion?]

sub'd.

this is really cool cs900!

[Spitlebug]

Welded tubes? Odd. I guess it's easier to do when you don't have a CNC rig?

[cs900]

yeah, it was a lot easier to thread that way. In addition the spacing on the merlin extrusion made it nearly impossible to thread the extrusion itself. well not so much the spacing, but the groove that runs down the side of the extrusion.

How is a welded seam as far as anno is concerned?

[cs900]

it's plug welded on the bottom with just a tiny fillet weld on top. The body will need to be powder coated more than likely

I missed the welds the first time and was looking at my email going

"what kinda crack is he on?!?!"


btw, it ano's just fine. the different alloys will produce a slightly different color, that's about it.

[cs900]

welds usually create a halo effect around the heat zone from the weld regardless of the weld alloy used.

news to me... although it makes sense.
