Gate lock fabrication

After installing the bay door gate we purchased at Watershed PDX, we needed to have a lock installed.
Here’s what the lock looks like after it was installed.

The black locking bar assembly on the left was purchased. The swinging latch that connects the gate to the locking bar is what I built.

I used three scrap pieces of steel.
7/8″ schedule 40 pipe, 1 1/2″ x 1/8″ flat bar stock & some random pipe with a 1 1/4″ inner diameter.

After I found these pieces, my first step was to cut the larger pipe in half using a fixture and guide to cut a straight line with and abrasive disc cutter.

After I completed the cut on one side. The larger pipe looked like this.

Before I could flip the pipe over and clamp it again for cutting, I needed to account for the 1/8″ kerf the abrasive disc cut made.
So I grabbed some 1/8″ wire and slipped some pieces in the existing cut slot.

Then I flipped the pipe over and cut open the other side.

After the second cut was made, I saw that the inside of the pipe was rusted and would make it tough to use as a sliding lock. After 2 minutes on the wire wheel, the rust on the right pipe is no longer an issue.

Here’s both pipes wire wheeled clean.

At this point, I’m ready to assemble the flat stock to the armature.
Here’s a picture of the fitup.

After this was welded together. I took the welder out to the bay area to clamp the open pipe around and weld the pipe back shut around the gate post. Not many pictures of this since my hands were full.
Here’s what the lock assembly looks like in its various states.
