I have a 100 lb Murray and love it. Murray is the next step in evolution from the LG. The best improvement is bronze bushings with grease zerks instead of Babbitt. I think it would be a fair buy in the mid to upper 2000's. Good luck.
I ran across an antique safe once that had alternating plates of tool steel and cast iron to discourage drilling and torching and vials of tear gas to further discourage misbehavior.
Procedure from an old blacksmithing book: Use wood wedge, then metal wedge at 45 degrees to the wood wedge. Soak in a bucket of linseed oil for a week. Works for me.
A 2 stroke powered abrasive disc works wonders. You will get 4 or 5 cuts out of a 7.00 disc for a cost of less than 2.00 per cut and it goes through a rail like a knife through butter.
The Houston Area Blacksmiths Assoc. website has a For Sale column that turns up lots of stuff. Phenix Knives in Bellville, TX may have a spare anvil. Good luck.
Just joking about needing help with the hammers, but I bought Clifton Ralphs video a few years back and certainly recommend it to anyone with a power hammer. I will try to get a photo of the helve but give me a day or two.
I forgot the 25 lb. Moloch in the barn. I guess I don't really need it. Anybody want it? 110 volt motor, plug and play, might need a new belt. 979-830-3578
