  1. I recently found this old belt grinder at an electrical surplus shop just sitting on the ground. I bought the thing and brought it home but cannot find any information on this thing. The guy told me at the store he thought it was a 2"x72" belt grinder but I measured the loop around all the wheels and only measured 60"-63" after you let out all the adjustment. Also the two wheels towards the back are both 1-3/4" wide wheels however the bottom wheel in the front where the platten connects is only 1-1/2" is that normal?? The only information on the cast aluminum frame states, "Sandmaster Products Los Angeles California." If anyone has any information on this thing or can answer my questions about the wheel sizes I'd really appreciate it.
  2. 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!
  3. Hello everyone, I was wondering if anyone out there has built a 2x72 grinder out of one of these (see attached picture). I love blacksmithing but since I am a carpenter by trade, fabricating machines doesn't come naturally to me, so any advice would be awesome. Buying a belt grinder isn't in the budget right now.
  4. Just completed the belt grinder build, I documented it in a ten part video series if anyone is interested.
  5. Hello guys I had this sander for some time I'm just wondering if any of you fellow blacksmiths used on like this 21/2x60 I'm just getting into blacksmithing thanks I tried google couldn't find much info
  6. 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!
  7. Ok so I have recently been getting into bladesmithing although I have been doing blacksmithing for a couple of years now. I have a small 2”x18” belt grinder at home which I have used for some small knives I have made but I go through belts incredibly fast and was looking to upgrade to a larger model. That being said the common 2”x72” belt grinder is set way out of my price range right now as the technical building of it is a bit beyond me and in Canada the only supplier sells them for about 2000 bucks. I have found this 6”x48” belt grinder though and think it looks like a promising option but I wanted to know if anyone has any experience working with such a wide belt and any problems I might face. Any advice appreciated.
  8. I have just put together a blog tutorial on how i built my belt grinder. It is heavy with pictures and dimensions for the do it yourselfer. I hope you enjoy... please comment if you think i should change or edit anything. thanks. http://metalantontools.blogspot.com/2015/05/metalantons-2-x-72-belt-grinder-build.html

  10. Hi, my friends. There is my self made machines for my blacksmith workshop.
  11. My grinder in a box (GIB) should be waiting for me when I get home tonight. It’s one of the 2 x 72” kits. I’m hoping to get an idea from some of the experienced knife folks out there as to what motor may be appropriate in terms of hp and RPM. I had initially settled on 2 hp and 3600 rpm with a VFD speed control, but in reading the various forums some comments made me re consider this decision. Some folks pointed out that with the VFD, if you are running at 50% speed your torque is substantially reduced as well. This is something I am currently researching. They also pointed out that running at less than full RPM; the fan won’t be cooling as efficiently, leading to potential motor overheating issues. I’m new to knife making but not too mechanics so I realize there are choices you can make in terms of drive pulley diameter to change belt speeds as well, but I haven’t found any sort of chart that spells out appropriate surface footages etc. for the different grit belts so I can better bracket in my desired speeds. Any comments or suggestions from the more experienced folks would be much appreciated so I can get the appropriated drive parts on the way. I've found little bits and pieces on my research, but nothing approaching any sort of consensus (not that I expect too with this crowd) Thanks Brian
  12. Been working on it for a while and was hunting down parts for it for a fair time. Managed to salvage the 2 wheels from a scraped belt sander, made the shaft out of a bit of bar and added 2 bearings I found to it. The welding is rather crude as it was my first welding project (they seem to hold) and first welder I have used. Just needing to attach the platter thing to the tool and I have since added a stick off my lemon tree to provide tension for the motor and the main spindle. Over all I am happy with it seem to have enough power to bite into material. Waiting for the ZIrconia belts to arrive to get into some metal grinding. . Open to criticism on all fronts of this project, I know it is not fantastic or good looking, but at this stage it is functional and cost me peanuts, If I only found a scrapped trampoline it would have cost me $0 to build. Here is a video as everyone loves videos:
  13. I have had a 2x48 belt grinder for a few years and am in the processes of upgrading to a 2x72. I also have a large Baldor 2x12 pedestal grinder with stone wheels. Since getting the belt grinder I have not used the pedestal grinder. Room is my shop is limited and I am thinking about selling the grinder since it has not been used in over year. Can anyone think of an operation where a stone wheel would be preferred to an abrasive belt? I hate to sell it if I’m going to need it again.
