  1. I am working on a homemade power hammer and have made bearing housings from 3/4 wall 2-1/2” ID Tubing to accept a pressed in  SAE 660 bronze sleeve bearing with a figure 8 shaped groove to allow oil to reach all parts of the bearings from the oil cups supply. 

    The shaft is 2” OD solid and will be built very similar in mechanics to a little giant and will have approximately a 50 lb ram

    My design is set up like a standard rigid babbitt journal bearing (NOT split)

    The bearing is 2”id x 2-1/2” od x 3” long. Do you think this pressed in leaded bronze bearing will hold up?

    Thank you

  2. I see alot of Hawks being made of tool steel, i plan on using mild steel and adding a tool steel bit.... Is this ok, i like spike hawks! What are the pros and cons to solid tool steel vs mild with a tool steel bit? And for slit and drift method for spike hawks what size blank do you guys use? I was planning on 1x4inch square bar. Thanks guys

  3. Wow Chris i was just looking at all the posts youve made of hawks and knives youve made..... WOW! You are a talented man! Knives and hawks are what im interested in making, but still setting up shop and making a appalachian power hammer and belt grinder. I hope to scratch the surface of what you can do, keep posting pictures! Any books thatd youd recommend? Once again good work

  4. Everything mac, use 2" tubeing and 6005 sealed bearing and a 24 mm bolt to make your idler pulleys. Very light machining this way probabaly .020 id removal to accept the bearing and you will want a 1/32 taper from the center of the idler to the outside on the left and right side to make the belt track right! This is what i did and with the minimal stock removal its cheap to have turned on a lathe for you! McMaster Carr is a good place to get good prices if you are in the US! Good luck and im tearing apart my treadmill tomorrow haha thanks for the help guys

    This is what i did

  5. I am wanting to build a appalachian power hammer but i want to make it tire drive for the flywheel effect! I have seen some pictures of how these are set up but i cant seem to locate them now. Does anyone have a picture of the tire mounting and the rod drive design? I assume its a hub on one side and the rod on the cam on the other side? I wasnt sure how to mount to make the cam and rod clear either the hub on one side or the motor on the other side! Whats the best approach?

  6. Hey guys i have lots of grade 8 bolts 1in diameter with a smooth 12in shank and i also have 4340 axels of various diameters, i wanna make tomahawks, drifts, and hardy tools out of them, my question is which is a better steel, ive heard that G8 bolts are simalar or 4140....... Fact or crap?
