I need to lower the bridge on a new, oversized, stainless 5" frame. It is higher than those on my older guns, and is high enough to keep a round from trying to chamber.
Any pointers to how to lower this by hand would be appreciated.
Here's a pic of the setup I used:
It was in this thread titled "Lowering Frame Bed"...
...which contains a lot of other good info.
OK, I got the general idea. I'll fashion a drum to wrap and do it by hand/eye. In doing something like this, I normally score the surface with a coarse paper, than make the marks go away.
For me, the little block of wood and the drill (as a roller atop the dust hood) to positively locate the non-working end of the tubing was the secret. By fixing that end all I had to concentrate on was keeping the working end of the tube centered in the bed.
With only one end of the tube to worry about, it sped up the job. It still took several hours, as I had a lot of lowering to do.
Make yourself a big pot of coffee!
And here's a side view which may better show the setup:
Without it, I just knew I'd have ended up with an hourglass-shaped bed. Never had the knack for doing something like that free-handed without messing it up!
