It followed me home

For the light little ones they were often used in the jewelry trades for coining and ornamental die work.

I saw the use of a large one (250 kg?) in Germany where a smith used it to turn a chunk of 2" sq stock into a hoe. The drop hammer was used to take each side out of the main piece with a single blow.

How would a motor lift and drop that hammer? How does the lifting mechanism work?

My dad used to drive a propane truck, going to houses and filling their tanks. I told him once that I could use a propane tank, and he mentioned a 275 gallon tank on a trailer. That seemed a bit large to me, but then he remembered a smaller tank that came off of a tractor or a truck. It is a 43 gallon (358 pound) tank, with valves for liquid, vapor, bleed off, vapor return, etc. And of course, a pop-off valve just in case someone fills it too full. This tank is heavy! I could lift one end, but we used a tractor's front end loader to load it into my truck.

I still need to get the gaskets inspected, get a cap for one of the return lines, paint it, and get it filled. So, expect to see some questions about propane forges and burners soon. (I know there are several blueprints, and a million articles on the internet.)

You don't use a motor you pull on the rope and then let go. Drop hammers are not cycle machines like a trip hammer.

Larger ones are sometimes board hammers---there is a sturdy board fastened to the upper die that a motor driven wheel engages to raise it. when it reaches the top the wheel pops off and the thing "drops".

But I have seen a video of a motorized drop hammer? Especially a 250 pounder, you would need some help lifting that one, no? The video of it can be seen here:

New guy here, here are a few pictures of what I picked up last week in Sacramento, CA. Used tool dealer that I met at a Renn Faire. The post vise is a Fisher 119lbs with 6-1/4" jaws. The large post drills I did not buy too big for my shop ... If anyone out there is interested I can send you the information. The anvil vises 3 are Stewart handy workers Chicago flexable shaft co. pat date sept 1916. There is a Cheney anvil vise no 40 pat date is nov 18 1879 from fulton iron and engine works.

Cool stuff, those anvil vises are cast iron? Welcome too by the way!

the drop hammer, the heavy ones can also have a motor and gearbox attched to a large flat belt type pulley, the belt just lays over the pulley, with the motor on the pulley spins and when you pull on the rope it makes it very easy to lift the 250 lb drop hammer, i may be ablt to get pics if anyone is interested in seeing it

this is one of the last thing to follow me home, its a kalamazoo 9" bandsaw, its a real nice saw, the other is an electric kiln which i havent taken any pictures of,
