We're committed to using old hardware when we can during the construction and renovation of our buildings. The latest project is putting doors on the tractor shed attached to the house. While salvaged strap hinges are plentiful in our area, due to all the German barns being torn down, the pintles are not. They are so difficult to retrieve from the old timber frames that they often get destroyed or buried with the rubble. When you can find matching sets of hinges and pintles, you grab them whether you need them or not. As old pintles were made for thick timber frames they do not adapt to today's standard construction. So time to make old technology fit new technique.
The old hand forged iron pintle
In the image below the 2"x8" board represents the new door frame jack studs. The smaller 3/4" board on the left is the exterior siding. The old pintle is too long, the threads are buggered, and the hole to be drilled to accept the square shank needed to be to large and could weaken the jack studs.
First thing is to cut of the shank from the hinge pin.
Next cut the new 3/4" threaded rod to the proper length
Mocking it up to make sure we're on the right track. Note the remaining length of square shank on the pin will be sunk into the siding, so a square hole will need to be chiseled into the board after the 3/4" hole is drilled through the jack studs. This square "socket" will help keep the hinge pin plumb and not rotate out of alignment from the weight of the door over time.
Set up for welding
The welded threaded rod and pin next to the old shank. We'll keep the hand forged shank and square nut for future unknown projects or perhaps give it to an iron smith to be reworked for another purpose.
The complete assembly with the 30" heavy iron hinge. These will be used for a set of 48" wide wood plank carriage house style doors to close an 8' opening.
