ok guys i am finally gonna start this, i have made almost in a cad program and will start to machine my parts next week

still i have a problem, how should i run my pump arm

my idea does require to mill a slot in the body, but i am ok with that.
xsiv want to run the pump arm to the top where the cocking pin is.

what do you guys think?

a lot of people do it your way, I've never seen it done XSiv's way, I think it would be easier XSiv's way because you would just have to bend a wire

think it looks better your was. But X way is simpler

well i agree that milling the body and everything isnt the simple way, but i thing the final product will be good

WHOA COWBOY...I said a a L shaped extension coming off of both sides running parrallel to the body then turn ing up and coming across body......This way NO milling is involved except on the hammer

NO WIRE!!!!!!!!!!!!!!!!!!

Folded and bend Sheet metal

no i say my way needs milling and that the path i chose, and i have designed something special for the valve

ok then why did you make a topic asking people what they think with you already having a preconcieved and unchanging way that you want to do it........

04-13-2009, 04:10 AM
well i wanted to see if people had any other ideas, that might be better than mine

Let me know in a month or so and I can mill that for you for a very low price.

Hey hey.......its because im bigger than him he generally sees it my way :dodgy:

right....i plan to make a new cup seal and pin together, but shape the cup seal like the rocket valve

why not do an over barrel type?
the way I did it with my spump worked out really well and was MUCH easier than my original plan

well we were going for a shotgun look to it

04-15-2009, 06:11 PM
^^ yea but the barrel type is easier, the shotgun style would be more pump with a milsim touch

Maybe try and make an Autococker stlyle back block - and run a screw to where the adjuster screw is for the spring/ball bearing assembly is in the bolt? that way you're only milling the striker. If you're really brave - drill + tap the striker from the back so you can use a cocking rod and independantly cock the striker - that way you could glue a piece of rod (or cut bolt pin) to steady the striker - and you wouldn't have to mill it - just drill/tap. I just realized though - you'd have to come up with a custom Velocity adjuster to do this. as you'd need a hole in the center for the cocking rod. if you use a small enough diameter rod you might be able to drill a hole in the center of the existing screw to allow the rod to pass through it. Needless to say - it'd be a fair amount of custom work - and you'd have a pump Spyder that operated virtually the same as a pump Cocker.

^ but your striker has to be seperated from your bolt if you just hook your pumparm to your striker how would youclose the bolt to shhot?

04-16-2009, 06:03 PM
well that is a good idea but i already have a cocker pump and that is way too much work

04-16-2009, 06:37 PM
^ but your striker has to be seperated from your bolt if you just hook your pumparm to your striker how would youclose the bolt to shhot?

Same as a cocker pump - the bolt would be connected to the block - and the striker would have a rod/cut off piece of bolt pin to stabilize it.

oh yeah shoot dunno what I was thinking!

DON'T cut the PIN.

SLOT your striker. with a dremel with a cut off wheel it takes an entire 5 minutes or so to cut the slot out on the striker. it's a much better method than cutting the pin and gluing it into the striker

04-17-2009, 02:49 AM
I can attest to that, I slotted the striker in my MR1.

any more suggestions or anything is welcomed, i am open to all ideas
i am gonna be using a mill for all this, but i have 2 weeks, meaning 4 days in the lab before school ends

The best advice I can give is to check out the lin kin vikes sig cant get the whole prossess laid out any simpler then that.

project never got past the design phase with a few prototype pieces being made ended up trading the mr-1 for a tank i think
