  1. Smiths, I was given an angle grinder for my birthday. I was vague with my birthday list, never having used an angle grinder before. I have not had time to research them, nor to test this one out. My father-in-law is a very handy person and did the research on this one, so I'm guessing it will do what I need it to. There is a limited window on returns, so I was hoping you might be able to lend me the benefit of your experience and confirm: will this do the job as a general-purpose angle grinder in a hobby shop? The details of the grinder are in the pictures below. Little Bean for sc
  2. I'm putting together my first 2x72 belt grinder build. Using the simplistic stacked tubing design with vertical compression belt adjuster. I sourced a 1.75hp DC motor from a treadmill as drive power for the time being. Can't really afford an AC motor with VFD at this moment. The DC motor works fine and the MC35 speed controller also works great. My problem is that after taking the flywheel off and measuring the arbor I found it to be 17mm (.669") instead of the standard 5/8" arbor. My intension was to purchase a machined aluminum wheel package to complete my build. Unfortun
  3. Here is the new grinder I built. I am completely new to the 2x72 format. Still kind of new to blacksmithing. I have been in it about 1.5 years. I got a forge, anvil, leg vise. I’ve made some hooks, hearts, bottle openers, and 2 knives. I have a friend tell me 3m Cubitron is the best and Norton is pretty good. Although offered no place to shop for one. I understand that ceramic is the best, zirconia is next best, aluminum silica is the bottom. I have found a online shop called Combat Abrasives. Where is the best place to buy belts? knife supply store? Amazon? Other Brands? Links? startin
  4. Well, I finished my tire hammer so it's on to the next project. I decided that I wanted a belt grinder more versatile than my old Grizzly 2x72. I started this project last Thursday. I am using a 2.25hp treadmill and mc-60 controller. I CAD drew the platen and attachments and had a local fab shop laser cut them for me. I also had them cut a straight platen for upright work. I bought the rollers from Oregon blade maker. Very nice quality. I plan on adding a ten inch contact wheel and arm.I should have everything finished and running tomorrow. Then to build some jigs for
  5. Not that I can't weld - I just didn't feel like it. I used 18 and 12 inch pieces of Unistrut and 3/8" and 1/2" nuts & bolts with the right angle brackets and plates. I did cheat and tack in an 8-32 nut for the tracking adjuster. I was going to epoxy a 1/4-20 t-nut into the hole but I ran out of epoxy and the 8-32 gives a finer adjustment. Motor is a 3/4 horse washing machine motor. 2 speeds - 1140 and 1750 rpm. With a 6" drive wheel I calculated the belt speed at about 2200 fpm on low, 3400 on high. Spring is from the same washing machine. For the jackshaft I drilled ou
  6. Howdy! Was lucky enough to find this beast for a song but, whoever had it before me took off any identifying information. Anybody ever seen one of these? Anybody know the deal with the fat hollow pulley in the back left? Anyway, need to replace a synchronous drive wheel, and belt from the motor to the transmission... Any information will be greatly appreciated, I've been searching for weeks now... Thank you for your time!
  7. I just got the aforementioned grinder. Is there anyone making aftermarket parts or adapters that would bring this grinder up to date with is younger brother the BIII? Any and all help is much appreciated and thank you in advance for your time. In addition what is the type of frame motor that Bader uses?

  8. Hello, new member from near Wichita, Ks. I have only been playing with smithing for a few months but find it very rewarding and therapudic. Grandfather was a blacksmith but he passes when I was only 7 so I have always had an interest in the craft but been too busy with life until now. I admit the show forged in fire did respark my interest and bring me to where I am now. I built a modified version of the freon bottle mini forge, purchased a Oregon blade maker 2x72 belt grinder, and made a striking anvil from 2 - 60# blocks of steel. I have made 5 knives learning something with every one. Not l
  9. I am going to make my own belt grinder, but I need to know if a 3/4 hp motor with 1750 rpm will be sufficient? Can I connect two motors to increase load weight before shutdown?
  10. Hand Cranked Forge Blower Build Here are the pictures of my Hand Cranked Forge Blower Build, made using a Mole Hand Grinder found on the internet (which has a 1 to 10 gear ratio), some old side pannels off a PC, a few small rivets, some protective steel corners that came with a kitchen worktop and some 12mm Aluminium angle iron. Here are the picture's of the grinder on its own. The back piece with the right angled brackets. Starting to rivet together the fan blade using 12mm aluminium angle iron. Cutting the brackets to size and drilling the holes for the rivets. After riveting t
  11. I've been working on my own grinder for a week or so now, following Dan Comeau's BG272 plans. If I would of had more time with a CNC mill I would of built a KMG clone, but ohh well. I have one question. Due to my budget, I had to get the only used motor I could find locally. A 3HP US Motors. The only downside is that the shaft is 1-1/8" and no one sells a drive wheel with that bore. Unfortunately I do not have the stock to turn a wheel this size on the lathe. Any recommendations on how to get a drive wheel fitted on the 1-1/8" shaft? Thank you. Here's some progress.
  12. a late merry Christmas to everyone on I forge iron! I am looking to get belt grinder, not a little knife sharpening one, but hopefully a big industrial one, something with maybe a 4" belt or so. if any one would have a link to a good one, a recommendation, or knows of a brand/maker, it would be greatly appreciated!
  13. I'm thinking about converting my Central Machinery (harbor freight) 6X48 belt sander into a 2X72 grinder. I think the motor is on its last leg because it's bogging down much faster than I remember, and I know there's a lot of work involved, but I don't have much money for the darn thing because I fund my shop through part time shop sales. I don't exactly know where to start on this project, but I figure y'all are the best group of people to ask. Seems like a bunch of you have done home-built 2X72 jobs, and I really think the conversion would increase my productivity and allow me to work to
  14. Belt Grinder Info Rabbit Holes I have been spending a lot of time looking into what it would take to have a good 2 x 72 (inch) belt grinder (e.g. KMG). I am in Eagle River (AK). Just Buy One! Maybe Not... I found that companies do not ship here, or the cost is (not surprisingly) quite high. Before doing anything particularly foolish I am looking to you all for suggestions. Make or Buy? Is there a good option... I have not found sufficient info to be comfortable making a grinder, and in my ignorance I would likely get started and end up spending "a lot of money" and be the owner of a pile of p
  15. I just finished making a 130# granite rock anvil that I cut with a 15 amp angle grinder. It has a 1/4 inch thick steel band around the surface edge to help prevent the face from chipping. It took me about 45 minutes to cut the anvil and another hour to add the steel band. I posted a couple of videos of the finished project on youtube at... . I have not forged on the anvil yet, but it does have excellent hammer rebound. I am not the first to think of using granite for an anvil; Wayne Goddard briefly discussed using a granite slab as an anvil in his 2001 book "The $50 Knife Shop." There is

    Beveling

    Hi everyone, second day of smithing... Sort of. Can I get a short tutorial on how to hammer a bevel? I don't want to grind too much and lose density in the metal. Thanks!
  17. Well it is almost finished ! it is a custom build KMG type grinder that I have posted a ton of times when asked the question of what grinder should I get /build many will recognize it and yes custom ! as myself and a friend have changed many things to make it more worker friendly and easier to operate . with out due here are a few photos 7 attached at this location . http://imgur.com/epQNnMW,USXNl6L,SPcTmE5,ql1lbop,8OVubzB,nAFuyaa,cAxHFF4#0 Enjoy & Best Regards Sam
  18. Hello all, I do hope this is the correct place for this question. I'm in the process of building a 2"X72" belt grinder - doing as much as possible myself - my time is cheap since I'm retired. Question about the wheels used on the grinder - The motor drive wheel I built from a 4" aluminum rod - 2" wide and flat across the top. Is flat across the top normal? OR do they have a slight crown? If so, how much of a crown - 1/8"? The tracking wheel (this is the spring loaded wheel) - I'd plan to make it from 3" diameter aluminum rod with 1/2" ID roller bearings. Question, does this tracking
