Sniper pump project

Ok more from the shop and the world of cnc.

Here is the story. In some of my other threads you might have seen that I recently acquired a pump kit for my cocker that has the ego mod. It was 30 buck how can you go wrong right? You can buy this kit thats how. the fit is sloppy and their is not torsional control of the pump arm. It feels like I paid 30 bucks if you know what i mean. now I have made a pump kit for a Spyder AMG and it turned out great smooth as can be very little torsional play dual pump rods great. Never actually finished the rest of the gun but the pump action feel great. Any how since I know that I can make a pretty nice pump handle and the sniper is the standard by which others are judged i figure I'm overdue to try my hand. So I designed it up and started the machining yesterday. here are the vids I have so far.

you may notice that I am making 4 of these once I get them put together and tested I will be selling the other 3 so look for a sale on them probably next week some time

taking longer than I thought it would. Their was a lot of bugs with the first code I posted nothing that hurt the parts but just things that were buggy. the machine would stop every once in a while and other just frustrating things. all in all it took me from 6pm last friday untill about 2 am sunday to get them out of the plate. I reposted the gcode to ease up on the code problems and it should run un attended now while I am at my day job. I was not just doing that all week so far though I was working on the lathe while the mill was working since I cant take 2 vids at once I just took some pictures instead.



this is actually the second op for the main pump bar



close up of the nub removal op



drilling the weight reduction hole. I thought this was important because all of the guide rod components are 303 stainless so they are relatively heavy



taking the first cut to bring the dia down to the correct size



I think this is the final pass for this side. I forgot to take a picture of the next step but I would then change tools to a left hand bit and finish the left side of the stock to the proper dia.



these are the first ops of the guide rod plates






some more of the process. As I type the machine is still cutting so they are not quite finished.



and last but not least here are the components that i have done or one step from done the guide rods need threaded and the hole need tapped int the pump plates. but other than that they are pretty much done.

You're very brave.

Those are some nice parts, glad nothing went haywire while you were at work.
