Chopper tee piston problem

[ckman]

hey guys so i am making a 3/4 barrel sealing valve and it is all going to be made out of copper but the only problem is that the tee i am trying to house the piston in has blocks running the whole gap then they stop so the piston cant move across to the other side and i tried taking it out with a dremel but it barely did any thing

so heres my question do they sell tees with no little blocks in them

that might have seemed like a dumb question but im new wit piston valves and copper

I had the same problem. I reduced the diameter of the sealing end of the piston. Works fine.

I would not put the piston in the tee but in a pipe coming from the back of the tee

If you can, find a FTG adapter for the back of your tee. Its what i did in my gun, and it makes the overall look much better than if you hadnt used it.

an FTG adapter fits perfectly inside the fitting... its cool stuff.
