Hey all I'm new here. Hope this is the right gate to post my new project. I'm combining what I feel are the best part of a Crosman 1400 with a 2100.
My goal is to create a rifle with more power hopefully 16+ ftlbs in 15 pumps while correcting some of the problems inherent in the 766/2100 platform.
1. More power.
To achieve this I went with the larger valve of a 760.
2. Less pumping.
I plan to pump to higher pressures (overpump). I do not want to pump 20+ times. So I am modifying The pump tube and piston from the 1400. Longer stroke = less pumps. Also using these 1400 parts will give me an easy to adjust steel piston with a 2100 pump cup. I may change to flat top system later. I have a flat top valve head available, but the old 1400 piston cup was shot and changing that part is beyond my current reach.
3. Barrel Wiggle
The 2100 does not have a very stout attachment between the pump tube and barrel shroud. I plan to silver solder or weld an attachment point to the steel pump pivot of the 1400 then mechanically attach the barrel to this L-shaped bracket.
Of course lighter valve spring, heavier hammer spring, lightened trigger, barrel crowning and such....
The plastic has to go. I will make a wood stock set for the rifle. Probably fill and paint or duracoat the receiver halves and other metal parts.
So, what do you guys think? I'm open to advice.
