Title: Little help needed/ my bullpup build
Post by: bonnox on June 09, 2014, 12:40:36 AM
Just a quick question, I know most of the 22xx parts are interchangeable, but is the 2260 trigger unit compatable with the 2250 main tube ? Am trying to make a bullpup version and need a 'grip less' trigger unit,
Cheers
Tony

will work on 2250 tube.  Would like to see pictures of the bullpup when finished.  Never been happy enough with the way mine looked to post pictures.

Early days yet, I have the stock sketched out on a piece of pine plank at the moment going to try a rough model on cheap wood before I start cutting up something expensive, I just need to get the trigger and linkage sorted again I have it roughly sketched but nothing made, can't start yet till I get my pieces made, I'm currently having a hw77 barrel tuned down to fit my steel breech to give it a chunkier look, with a 1/2" unf thread for a decent muzzle brake, once I got all the pieces together I'll get it put together

So here is my first update of my bullpup design, I have the new barrel back and have it fitted, got the basic design sketched and cut out, I have the trigger and bits fitted just need to figure the technical bits out then I'll make a start on the stock properly here is some picks:
1: basic sketch of what I want to do.  http://i1317.photobucket.com/albums/t640/bonnox/f16f11bed0afcaf96fe1a4bdaed2d765_zps85407800.jpg (http://i1317.photobucket.com/albums/t640/bonnox/f16f11bed0afcaf96fe1a4bdaed2d765_zps85407800.jpg)
2: the new barrel fitted, it's a cut down weirauch 77 barrel with half inch unf thread for a moderator

3: trigger and springs etc.

couple of points, yes I know they are screws they are there so I can adjust move etc to figure the bits out, and yes that is a key it's just something I had lying around to again figure out if it will work I will be swapping it out eventually, now I just need to get something to connect the trigger to the 'key' so it will be a direct pull and another spring to return the key to off, if you get my meaning,
And yes I know it's only pine that cos iv never made a stock before and pine is cheap, once iv got it figured out and working then I'll make a proper one in decent hardwood, comments welcome

Trigger linkage designed and working really well 'fired' every time I pulled it, just need a return spring somewhere to put the sear trigger back to neutral although it seems to work with out it, going to start work on the stock tomorrow now

Here's a picture of the rough working trigger linkage from trigger to sear
