Pin press construction pics

I built a pin press yesterday. The cost was $17 for an 8 ton bottle jack from Wal-Mart. The rest of the materials I had laying around. I used a U channel piece of metal for the top and bottom plates. Square pipe (1"1/2" I think) for the pillers with threaded rod through the square pipe connecting the top and bottom plates.



here you can see the threaded rod in place and a square pipe standing in place.



this shows it all bolted together. I pumped it up just bolted together and it held. I welded the whole thing up anyway since I like to weld. If you don't weld, it would be a 15 minute job at your local weldor so it wouldn't be that much.


I made 'points' out of 01 rod I had. I heat treated them with a torch to get them hard. I also mounted an extra piece 1/4" plate to the top part of the press to spread out the pressure a bit.



Here it is pretty much done. I knew this would be 'tippy' to the front from the start as the base was narrow. I figured I'd bolt it to a board or clamp it in my vise to use. I ended up welding some angle iron to the front of it (not shown here) to keep it from falling over when pumping it.



There are a few more pictures of the process at this link...

Nice contraption. I had never thought of a press for pins. ( i am a newbie at this ) I have just peened with a large hammer. Also have not pinned steel on steel just wood. Does peening the pin not work with steel on steel?

hammering works, this is just another way to skin the cat.

Nice work Tracy.I need to build one myself.
Holmsy2000,Brett you wouldnt want to use this for your makers mark as there would be to much movement.With a makers mark you need a jig that only allows the punch to move up and down with little to no side play and a way to keep your blade from moving.

mcahron, thanks for the tips. i wasnt planning on useing it as is for the mark, more planning on having a jig to hold it and then just use the press instead of a hammer.
