  1. Both vids are working for me. Yes I have a Bradley Compact, same as yours just smaller. Try tightening the nuts on the left and right sides of the rubbers a 1/2 turn or more. This will put more compression on the rubbers and smooth out the action of the ram when running it faster and it will make it hit harder. I can see your rubbers are a bit loose in your 1st vid and the ram flutters and flops a bit when you pick up speed. Also if there isn't enough compression on the rubbers the top of the ram can get thrown up too high and contact the linkage, don't let that happen. It looks like you're missing the middle bolt in the rectangle cut out in the frame. There are three bolts/jam nuts that adjust the tightness of the rear guide. Top and bottom bolts pull the guide away from the ram, the middle one pushes it in. There are also two more bolts on the side of the frame that clamp the guide in position after the adjustment is made. Hope this makes sense, after you stare at it long enough you should be able to figure it out. Here is a parts list and some basic info for your hammer http://www.newenglandblacksmiths.org/bradley-compact/ Feel free to ask questions I gone over ever inch of my hammer and use it quite a bit.
  2. I have a 100lber, I use a 2 ply leather belt with some kind of fabric glued in between the layers. Works great no stretch haven't treated the leather for 10+ years still looks perfect. A couple of tips Keep your rear guide adjusted a tight as you can with out making the ram drag = less stress on the front guide while off centered hammering. Keep the lever in the proper orientation so you can properly clamp the pitman. If the pitman slips out of the sleeve while forging you can break the sleeve casting. In your video it looks like you could use more compression on your rubbers. Do you have your anvil bolted tight to your frame? I use a piece of 1/2 plywood with saw kerfs 1" or so in between the hammer and anvil. You need a cushion in between. Apologies if you know this already , just my experience with my hammer.
  3. Variable speed. Wire wheels, grinding and sanding discs so much nicer at low to medium speed. Haven't touched my favorite Makitas since I got one.
  4. Nice anvil block, what is it 10"x10" hot rolled? Who is your steel supplier?
  5. I had mine tested at a tire shop and I think they were in the low 60A range, I could double check my notes. There have been threads on this topic before with no real consensus. I made new rubbers from 70A urethane and it seems a bit to hard. Others have mentioned higher hardness values.
  6. I believe many fork tines are currently made from boron steel like 15b30/15b41. I made flat dies for a press with this steel and it seems to hold up ok so far. I was able to band saw, drill and tap and use with no additional heat treat.
  7. You will not get rubbers from Cortland, they sold that to Bruce Wallace, he is a bit touchy to deal with, I would guess that he has zero info on your hammer. Make the mold or cut down Giesler's if they are big enough.Your vulcanizer can maybe test the hardness of your original rubbers. I used urethane rod and made rubbers for my Bradley, 70 duro seemed a bit hard.
  8. Beaudry, I have the same issue with the dies on my Bradley. They are the original dies which are fairly soft. I think old school dies tend softer maybe worried about projectile cracking? I think 4x4x8 is to large in 4140 to get full hard. S7 or 4340 or some other higher alloy might yield harder dies safely. Big dies like that are an investment for sure. Nathan R. makes tooling plates the full size of his dies for the same scale reason. I like the tool trays. You have a nice tight fit between your anvil and frame did you caulk it?
  9. The right arm looks a little shorter than the left in your photo. Measure both and compare length to replacements from Little Giant.
  10. I don't think you will ever get the arms to point uphill on a hammer without adjustable knuckles. Beaudry does have a point about arm length, it might be worth your time to get some pin to pin measurements from similar machines. Call Little Giant again and ask. I think Clifton Ralph said he did not like that style of spring tensioner or the single knuckle type, and favored converting to the two knuckle adjuster type. Although I'm not sure why your style wouldn't be fine if the spring fit. I made new tee-toggles for a 50lber using long grade 5 bolts with the tee welded on, and welded knuckles from bushing stock. Ken Kern shows it in his Little Giant book, which I no longer have a copy of. Longer arms might give you more throw/power as long as the ram doesn't hit the spring and knock it out into your face.
  11. Ideally your toggle links would be both be longer. Then you could double nut them so they wouldn't loosen.
