pinion shaft seal install tool

Everyone who knows me understands my obsession for properly installing seals. By always using an install tool and never just banging them in hoping not to damage them.
I come by my OTAD (obsessive tool acquisition disorder) honestly though. You see I literally started mechanicing before I was old enough to walk.
My dad would take me to the garage where he worked lay a furniture comforter on the floor and place me in the middle of it. For toys he would drop a few wrenches and small car parts on the blanket like a distributor or a carburetor for me to play with. I imagine that some huffy puffy woman from CPS would have a stroke to see someone treating an infant like that today.
I didn't start learning to be a Blacksmith or welder until I was 11 and bought my first Lathe when I was 14
Today in finishing up so work on my friend's Mack I had noticed the pinion shaft seal was beginning to seep a little so off comes the drive shaft and yolk so I could check the bearing for looseness then in goes a new seal and everything tightened up
TO install the seal I needed yet another seal install tool to be added to the dozens I already have which none of them were the correct size
As with many of these install tools I might only use them once or I might need to use them again and again Who knows.
For this one again I took the simplistic approach by locating a short piece of pipe near to the correct size, squared the ends on the lathe, then split a piece of 4" exhaust pipe and removed about 1 1/4" from it, rolled it into a tighter cylinder and pressed it inside of the heavier pipe then turned the protruding end to the correct length and tack welded a plat to the opposite end. Simple quick and easy

Then just because I may need these tools again in a 100 years I sprayed a little paint on them to prevent them from being discarded as scrap iron After I forget what they were

"Then just because I may need these tools again in a 100 years I sprayed a little paint on them to prevent them from being discarded as scrap iron After I forget what they were "

Hopefully with a label saying WHAT they are when you recognize that "I painted this so don't think it's scrap, but damned if I remember what it's for..."

At home I have a large 8-inch spike I very carefully bent in a certain shape, so I know it's a tool i made but I cannot remember what it does.

Some of the more obscurely special tools if there is a reasonable wat to do so I will stamp the use onto them or often times the part number of what they are used on.
But since part numbers change more frequently than a Politian's lies I usually don't bother with those
I am currently out of a paint marker so that is one thing on my need to order list
