Pump Stroke Too Hard

[zeroack]

I got mine running great with a small tweak up at the end of the rod. It was sticking pretty badly also. I also filed the burrs off the end that had formed from it getting stuck...etc. My question now is how many of you have made your own pump rods? When my pump is in it's "resting" state it's very drawn down into the rail. I'm wondering if I couldn't make a rod that's longer and shorten up the pump stroke even more. I went to the local hardware store and looked at there brass and steel rod selection. Smallest they go is 1/8th in.. However they do have some welding rod that was smaller and very stiff. I'd just need to knock off the flux.

Thanks for all the help again.

I have been working on making my own, and I have thrown a bunch of them in the trash in the process. Finding the right material is a chore, I have tried all kinds of stuff, regular round stock, filler rod, welding rod, and so far everything has been way to soft of a metal and doesn't last very long. I am planning on ordering some SS this week to give it a try next. So if you can find somebody that has some in stock that would be a lot easier.

Tempered steel will work and I'm pretty sure they sell it at depot or lowes. That's what Jays kits are made from.

Yeah I have checked at Lowe's and Home Depot locally, and neither of them carry it. I have to make a run to Norfolk today so I am probably going to hit Steel Services while I'm out there to see what I can find there.

I know this is really getting geeky but, one could temper there own mild steel couldn't they? Same as a knife when it needs tempered?

You'll need to get it stupid hot in order to do that tho. Putting it in your BBQ grill isn't going to cut it.

Cant use a lvl 10 with a pump.

what about the lvl10 makes it incompatible with a pump kit exactly?

[Ando]

I haven't tried myself but I believe it's due to the carriers. There's not a lot of wiggle room unlike a lvl 7 but where there's a will, there's a way.

People said the same thing about a E-Mag and ULT combo but I got one running 100% in mine. Took a lot of tinkering and about 3 tanks of air but it's rocking one.

Only thing with pump mags, the pump rod is eventually is going to tear up the bolt to the point that you'll have to replace it. Now the big question is are you willing to sacrifice a lvl 10 for the sake of not busting balls

I'm going to look at finding a softer metal to use for my pump rod. I'd rather replace my rod ever 3-5 games then replace a bolt ever year or so depending how much you use it. Until I find something suitable. I probably won't try to tune a lvl 10 for pump.

[zeroack]

No the BBQ wouldn't do it. But his forge would. If I got three or four rods for testing set up and had him temper them. That would work.

Pm jay8541 (I think that's it). I'm sure he can get you a replacement.

You said you could get us pics right?

I want to see a picture of:

your wave spring and blue bumper on your bolt. One pic from the top and one pic of the face.


Was the body and rail factory milled?

Jay doesn't have anymore rods.

I made up a "hanger" pump rod last night just to experiment with rod lengths. First one I made was about 5mm longer then the original one I had. It was ok but not the huge improvement I was looking for. Next one was a full 1cm longer and that was the ticket. Nice short tap on the front and it's setting the bolt just fine with no rubbing what so ever. Now I just need to find a better material to make it out of. I have to think that the clothes hanger rod is flexing a little compared to the stock one. So I'll run by the local parts store and see if the 1/8 inch steel rod will work for me. I think with a bit of filing it will be fine.
