  1. I use it as well but am not as happy with it. I am using a G4 Mac with OSX 10.4. It will save and open different files but I have difficulty with it still being in the same condition as saved. Emailing the files will get jumbled in transmission.

    It does have some nice features and capabilities, just doesn't work as well on my Mac. (sigh) and Mac doesn't really have a decent spreadsheet available and Textedit is pretty low end but usable.

  2. Clifton Ralph shows a lower die he built for his Murray that allowed him to do that. He removed the lower die and inserted a device like a C on its side then bent the stock clamped it with a header block and headed the stock. Seems he was using 1". I don't have a way of getting a clip of that as I have vhs tapes. may be some one else can provide a picture.

  3. I would suggest that you forgo the plate for a welding table and find an old exterior slab door. It is what I use. I also have gone from a 5' x 12' layout table to a 36"x64" and a 32"x64" table. Both from doors, Both on wheels Both the same height. They are flat and have usually 2 known straight edges and 1 or 2 square corners. Angle iron on the sides to create a place to clamp work straight and square.

    Most of my work is smaller than either table, but when I need to do a larger piece I can put them together. I also have a couple of third hands to assist in odd size pieces.

  4. Forging works the grain structure smaller. Out of the bloom it is pretty rough. forge it weld it back to it self as a big bar again. once refined. forge again, twice refined. guess what triple refined means. :)

    that does not take into consideration other impurities such as sulfur which create some trouble. There is a lot of discussion of this which I have read but have no knowledge of so use this to refine your search for answers. By the time it is triple refined you should be able to handle the problem. ;)

  5. Cast iron would handle heat a little better but would be prone to cracking under great loads. Steel would flex more and handle stress better at the cost of possibly softer braking (flex) under hi loads.

    That said, properly designed for the application, the point should be moot. Weight would be the first thought for racing, assuming safety was equivalent. Steel may prove to be lighter, as cast iron parts usually rely on mass for strength. I would have thought there would be an aluminum caliper for this application.

  6. 2ft x 3ft is a nice size for the hearth. This gives you room to set tools and have a coal supply ready to add as needed. the firepit measurements will depend on the size stock you intend to work but since you are unlikely to be working really big stuff I would recommend a truncated inverted pyramid about 9in square to 3in square. the total depth of your coal fire needs to be approximately 4 inches below your stock and 3-4 inches above your stock. Thus if you build your firepit to be 4 inches deep and flush with the hearth, you will heap your coal 3-4 inches above it.
    Then add on the tuyere to that. That is easily done with a pipe tee, (2 or 3 in). Air comes in from the side and ash and clinker pass straight through. Put a grate on top of 2 or 3 pieces of 1/2" rd to hold the coal and a door that will close on the bottom for an ash dump.

    I spent about 4 or 5 hrs building my last one to those proportions but not that big. The critical measurements are to have a good coal bed to match your air supply. Most blowers can handle the size above and more. Also have enough coal above and below your work. I have used rivet forges with substantially less coal but couldn't forge weld with out a lot of fussing in one. I also went too big on a firepot and had to blow a lot more air and burn more coal than necessary.

    There is a WIDE sweet spot here in which just about anything similar to the above will work. Have a ball.

  7. I allow a 55 gal drum for scrap. when it is near full I cull the inside stock for too short or no longer valued. Such as rebar pieces or bits of tubing. Then I haul it off and am done with it. It doesn't make me money, it is the overhead for running a clean shop.

  8. Stixman you are very motivated. :) take a breath because there is a bunch of stuff you are trying to learn in one gulp.

    Brazing is done with a welding tip. not a cutting attachment. you will need then actylene and oxygen to make it sparkle. the information for setting the regulators should come with the torch. You will need to practice a little I'd imagine. Which will bring out some more questions. Ask away. When you get some fuel gasses pick up some BRAZING rod. it will be brass. Also get Brazing flux.

    The nickel rod mentioned by QC is for WELDING. There is a difference. This is basic general info to get you started. There are nuances and exceptions for all the advice given. Stick with brazing since that is where you are headed. It will be a good thing to learn, many applications.

    Hope this helps.

  9. Alfie I assume that there is a hardy hole. Some of the first projects would be forging a heavy piece of steel to be a clean square edge for when you need it. just drop in the hardy hole and you have what you need. Goes for any other shape as well. The anvil is the base tool it doesn't have Everything you need but gives you the means to get it. I used a belt sander on mine and hit the edges a little to get rid of snags, little sharp edges that will tear up your work. If there are a lot then find the best part clean it up and work there.

  10. I had a semester of welding in college, but nothing til I had bought a tombstone and asked a welder friend how to do it. He gave me scrap rod and I got busy welding drums together to make a pontoon raft. I turned those drums every which way sorting through the piles of rods looking for those that were alike. :) mystery metal in the finest sense. I did mostly horizontal with one drum sitting on top of another but tackled all postion including laying over the drums and welding upside down. Had try it all.

    Now I use MIG most of the time but still burn the sticks as needed. And am still trying to be a welder.

  11. I use a draw knife on occasion, as well as fiber discs in an angle grinder. Til I get a belt grinder I use my belt sander in the vise for final operations.

    For wood I usually find broke shovel handles about as fast as I need them. iswitched to shovel handles as th hammer handles I have bought did not have good grain. Long handles seem to be a better grade.

  12. It'll do if you get the lining thick enough. Granpa just used dirt in his since clay wasn't handy. Sweany made one with river clay and it cracked. No big deal except at the end of the day he loaded to go home and when he pulled in an hour later, his forge was mostly gone, embers were in the cracks and lit the wood while driving.

  13. I started on stick and unknown composition rods, a wide variety of them. I decided to build an old fashioned pontoon boat out of drums so I started welding and blowing holes in all positions. I'd had some welding instruction 20 yrs before that and the weldor that gave me the rod answered my questions as they came up. after several weeks was finally able to weld two pieces of sheet metal cut from a drum with 1/8 6011. terribly unsuitable but an indication that I was mastering the process. When I got a MIG, the lessons I had learned about air gap and puddle control served me well. To get a good weld, start with a good fit and proper bevel/air gap. that is the part to learn. The process used then becomes easier.

  14. Looks like a Hay Budden. the holes you ask about are for porter bars while it was forged. The face is missing except for that little piece on the heel. What you have left there is either mild steel (soft) or wrought iron (Softer). any forging you do will ding it up pretty bad.

    Do you want to use it? Here is a case for welding up an anvil to get it back into action, or it can be used as is as a monument.

    My two cents.
