PCP pistol build challenge.
« on: July 10, 2018, 08:16:06 PM »
With all the BS talk of needing a FAL to purchase a PCP pistols lately I figure lets get some winter workshop home builds and/or Crosman mods going to show just how pointless this BS import ban actually is..

Whos up for a project?  Maybe a little competition to keep it interesting? 

Highest efficiency (shot count per cc)?
Largest cal?
Quietest report?
Highest total energy regardless of shot count or cal?
Lightest or most compact?
A combination of the above? Maybe a free for all?

Open to ideas and suggestions to kick of a fun group build and documentation of build thread.
Who of you tinkerers are keen? Mintie? Danny? Mike P? Brendon? Mike Dvlnme? Shiloh? Sam? Anyone else?

A .25 cal pistol would be fun for sure.. much better shot count per cc with 25.4gr .25cal kings compared to 44gr .30 cal jsb pellets and flatter shooting too.
You should be able to get plenty of pesting power from one.
While your baked bean can may be quiet it will be no match for my custom micro regged air efficiency  ;D

This should be good. Make sure its picture rich for us to admire. With my limited tools the best I could do is to make a pellet holder for the PRod mags, and change it back to pistol format.

Excellent idea. Lots of pictures I hope.
I wish I had a decent metal turning iathe and a mill and the required knowledge.
Trouble is I would have to give up my springer dedication and Hidayat would not approve.

PS. Please include photos of your workshop as well.

I have to admit that I have done something to this before to an old Triumph Toledo so it is not beneath me.

My mind has been racing on this, I think I will go for 25cal with a drop mounted 13ci tank and reg mounted under the barrel, I will use a Crosman 22xx grip frame but valve and hammer will be custom, MikeyP (P for pubes) unknowingly gave me a nice head start by building me a lovely stainless steel breech a few years ago which I have been trying to find a good enough use for. And of course a nice big CF suppressor to tame down the bark.

While I love pistols and get a real kick out of plinking with them carbines is where it's at for me so this will need to be able to attach a rear stock and balance like a proper carbine.

You use that breech I made you on an ugly gun and Iíll disown you.

Iím in just to make a prettier pistol than you...

Anyone else up for a build...

What about a shootout once their all done?
None of your business!
Am I being detained?

Oh it will be ugly alright, uglier the better. It's going to look like a super soaker with the bottle hanging under it.

Well I best get something started then.. nice to see a bit of interest.
I have a couple of hours free today so spent half an hour cleaning up the workshop of other projects and dragging out a bunch of alloy offcuts and barrels etc.

Most of you have seen/used my little workspace but for those that havn't and care even the slightest, here's a couple of pics.






I have lots of smaller offcuts, partially made parts, two incomplete crosman grips, and loads of 6" to 12" barrels of all cals that I thought Id use up on the first quick little pistol build.
Im going to use up a very short offcut of 1- 1/4" alloy air tube and throw together a little shorty plinker in .22cal to shoot the super heavy 25.4gr H&N rabbit magnum pellets. Probably just an open sight possum slayer.





So straight into the lathe went a piece of 1" alloy wich I turned into the start of a valve body.















Often when I built other PCPs I made a few extra parts at the same time while the lathe or mill was set up for a particular operation so this means I have a box full of partially complete parts that make following builds much quicker..
The front plug is bored for one of my std 8mm pistol fill probes. The following probe pics are of one I made a couple of weeks ago for my .308 pistol but will now fit this one too.














So here's the handful of parts 1.5 hours produced...
