For the most part pretty much the same tricks they use for making pump spyders. A lot of how you do it will depend on what tools you have available.

For example when I finally get around to doing my own Pump Piranha I'll be using my lathe to make up some front block screw in pump shafts to replace the LPC or plug as found on the R6. But I can do that since I've got that sort of tooling.

Huh? I don't think that sounds odd at all.... I've got a BOX of Piranha bodies and bits that I've picked up to do project guns with..... Now I just need to buy a box of TIME off ebay so I can do all the projects....

Sorry, more like instant disaster. The pin is needed not only to hold the parts togehter when playing semi but also to align the hammer and bolt so they can't turn in the bore.

Perhaps you are referring to how some folks cut them at an angle so they are disconnected but so that the bolt can still move the hammer back while the two angles stubs running in the body slot still manage to hold the parts in alignment.

Then you still need a way to cock the bolt to load a fresh ball.

This style is the closed bolt option.

Let's start with what tools you have available. I can offer up a couple of options but it would help if I knew what you've got to work with and what sort of skills you're most comfortable with.

Steve, I haven't forgotten about you. I'm pondering... and moving my computer room around... But I'm pondering while I'm doing it...

You've got two options. Closed bolt or open bolt.

The closed bolt way would pretty much follow the Spyder pumps that have often been done. They cut the pin that conects the bolt to the hammer. The first time they cock the hammer manuall and gas up. From there the hammer hits the valve and blows back to recock automatically. Meanwhile the pump rod is fixed to the bolt and you only need to cycle the bolt to load a new ball. Now the deal with this is that you're risking barrel rollouts but it can be done cheap and dirty and fairly easily.

The other way is open bolt. In this method you'll seal off the blowback air and leave the bolt and hammer connected. The pump and pump rod will not be directly connected to the bolt/hammer. Instead the pump rod will poke into the side through a slot and the bent in finger will push the whole works back and cock it. At that point the feedneck is open and a ball falls into place and is held there by the detent. You push the pump handle forward and the cocking finger moves forward and out of the way so the bolt and hammer can shoot ahead when you pull the trigger.

I'm planning on going with the second option for my own effort but I'll likely try the close bolt idea as well since it should result in a bit less kick.

For the closed bolt method you'd need to seal off most of the blowback air by getting a EVO solid bolt or filling in the blowback gas flats in the stock one with JBWeld or similar. From there remove the Oring on the hammer and if you find it still stutters or farts then grind a couple of 1/2 pencil sized groove down the length of the barrel.

Making up the pump handle will be partly up to what you've got or can get that'll either slip over the barrel or if you can figure out a way to use your limited tools to make a pump shaft that screws into the lower front threading or if you can modify one of the plugs that goes in there to accept a rod or if you can perhaps find one of those old style Bob Long super long LPC's that would work for a pump shaft.

For the pump handle it can be as cheap as some PVC pipe that fits over the barrel or if you have some woodworking ability make a custom looking one out of some nice hardwood.

Is this suggesting any options for you?
