I have seen the POR15, but never used it.
cmpman wrote:Well, I had hoped to start on the recouperator assembly, but I realize I will be needing some bearings for the ends and as well, I am going to have to blast and paint the components before assembling. So I decided to assemble the shields and install the cradle. None of these parts are prepped for installation, but it will give me a chance to straighten out some of the bent parts, and make some of the smaller items that are damaged like the hinge pins or special nuts and bolts.
I had heard that it occasionally happened where the guys would roll a gun and tow it for a bit before they realized. The right is a little bent, but the left brackets and shield are worse.
Here is the left shield, and you can see that it is not exactly at 90° angles.
Work with the press was slow. The armour plate has a memory to it.
Here you can see the bend on the left forward shield bracket. I will have to heat this and gently straighten it.
There was a little interference with the larger tires.
In later Cdn service, the shields were cut to allow clearance for this size, but I am restoring this gun to approx the 1970 time period, so I had to do some quick tire changing over to the 9X20s.
Here is a quick shot of the front with the shields temporarily in place.
A side shot of the carriage waiting for the cradle.
I had to wait for the snow to melt off the cradle before installing it.
I initially tried to install the cradle with one arc left on, but that proved to be impossible. Best bet is to remove both arcs.
The recoil mech went on without any problem.
Time for the barrel. It requires the sling be moved once the barrel is most of the way in, and be repositioned further up. All in all it went on well.
One thing I will never regret is buying a North American made crane. At the auction I got it from, I had my choice between an OTC 2 ton model or this 3 ton model. I went with the 3 ton and have never regretted it. I could not imagine doing this job with one of those Chinese made cherry pickers.
Once a few of the threads are showing, the nut will easily suck the barrel in.
While it is starting to look like a gun, pretty much all the pieces I installed this weekend will have to come off again in the spring.
Here is a last shot from the receiving end.
Still lots of small jobs to do yet, and the main shield brackets are going to have to get straightened, which may require me break all the welds on them and straighten them before rewelding. But at least the parts will be properly fitted and ready for sandblasting in the spring.
