Earlier this year I had to move my 250# little giant from where it sat to replace the timbers that had rotted out from underneath it. This required disassembly, moving it in pieces and reassembling in all took three days and I still didn’t have it setting on new timbers. After taking a long look at the cost and time it was going to take to put this hammer back into service the hammer was sold. My first intent was to build a press and rolling mill. After seeing the Catalog of User Built & JYH Hammers page at www.anvilfire.com (http://www.anvilfire.com) I started a three part project, hammer, press, and rolling mill. I’ve got the hammer done. After working with this hammer for a couple of days, if I didn’t already have most of the parts to build the press and mill I could get by just fine with just the hammer. It will do about 50% of the work that the 250# little giant would. The hardest part of this hammer was finding something to make the anvil out of. I solved this problem by using a base off of a crane. The rest came together fairly easily. If you would like to see other pictures of the hammer please go to my website: <a href ="http://www.bobcatcustoms.com"> Bobcatcustom</a> knives .

Bob,

That is real interesting. This is what tool time is all about. The pictures are great. It is a little difficult to determine how some things were done due to the pictures being taken as an overall and not part specific. Do you have text or drawings that explain the "Hows and Why's" of the workings and how you overcam problems?

I must say, I never expected to see the rear axel out of a car used for a power hammer, but now I want one.

Please give us more step by step stuff if you have it.

Now that looks like a project.
A man after my own heart.
I'd love to come see it run sometime.
Keep us up, OK?

Nice Job,

How is the operation, I use a 50lb. Little Giant-once, and liked the controll. I've been thinking of building a JYH as I cant seem to find a good used(read cheap) power hammer.

Thanks, William

Just mount a transmission on it and you have a variable speed power hammer. This could be kinda cool.

I am thinking that the brake drum used as a clutch would have plenty of controll, just never seen one in operation and was woundering how it comparred to a little Giant for control befor I go out and build one.

Thanks,

William

The brake drum clutch works like a dream. At its very best the clutch on the little giant would equal the JYH. I added a flywheel on the input of the differential. Now about the only thing that I am not sure if I could do with the hammer is crack eggs with it. I have some pictures on my website and have more to add along with a lot of text to go with which should be up on the sight within the next 2 days. This hammer was not all that hard to build I have had folders give me more problems and take longer to build. Most of the design work is already done within the differential. The rest of the specs were taken of a 50 lb. little giant as far as crank throw and hammer speed.
