Restoring an old powered hacksaw
  • 5,884
  • 57
Figured I'd share my restoration project! I've always found these old machines quite cool and when a neighbour offered me a defective one for free, I couldn't say no! :D This is the machine as I got it, it runs but won't lower the sawblade so you have to manually push it against the work piece, which becomes quite the challenge and dangerous as heck when it's moving back and forth. The thick bars protruding on the side are from an automatic feed system that's been cut off. By pure chance...
Scraping in all bearing surfaces on my Wards/Logan 10"
  • 15,903
  • 67
I've been working on my lathe off and on over the past several weeks or months, but I've been hesitant to start a thread documenting my progress (or lack thereof!) for fear of embarrassing myself. I'm increasingly confident that I'm going to end up with a very precise lathe rather than a very large pile of cast iron dust and tears, so I'm finally willing to share my progress. After creating a new cross-slide for my lathe some time ago, I'd already spent a lot of time scraping in the...
9A project completed
  • 13,232
  • 55
Some of you guys may remember this little crudball I acquired back in April... I had just completed the last project, the Seneca Falls #30 resto-mod,(project of the month) when this lathe found it's way to me via a friend of a friend. My friend, who is also a tool salesman, showed me a pic of this on his phone, which came from his friend, the seller, who now is a retired tool room supervisor. He had this in his back building just taking up space and wanted the room for some of his...
KO-Lee Cutter/Grinder Revamp
  • 10,675
  • 80
Perhaps you've seen this from other photos... It's a KO-Lee cutter grinder. It's a good platform and the table and all mechanisms are in excellent condition. I don't think this machine was used much in it's lifetime as there are very few signs of wear (hardly any at all really). The motor is the weak link. The bearings are going bad and vibration can be felt in the short shaft. The long shaft is OK. The seller told me about this when I got it. I'm guessing someone bumped a wheel...
Clausing 1771 Drill Press Restoration
  • 9,651
  • 20
I picked up a Clausing variable speed drill press from a Craigslist ad. I offered the guy $200.00 and he accepted. The drill press was in decent overall condition, and had a new motor on it. I disassembled the machine and cleaned up and painted everything. Mechanically, it was in very good condition, and the only real repair work I did was to straighten a few of the handle arms. One really nice feature is the table lift, which works great on that heavy table (btw: the table doesn't...
Construction details of A Complete 13.8 Volt, 50 Amp Power Supply
  • 7,767
  • 29
In part-1 Ioutlined the basic needs of an high current power supply and dealt with the protection circuits needed for safe operation. In part-2 I will deal with the construction of the unit itself including PCB layout, wiring diagrams and testing. Construction can be split up into five parts: 1. Construction and testing of the PCB. 2. Making the case 3. Pass transistors and heatsinks construction. 4. Wiring and testing of the transformer, rectifier and smoothing capacitors. 5...
Oil Can #2
  • 35,523
  • 81
I was greatly inspired by Hackmasters beautiful oil can clone. I decided to do a run of my own with a simpler design. It was suggested that I start a new thread here and not hijack the other thread. The plan was originally solid brass. I realized that the pump housing would add too much weight so I went with an aluminum pump housing. I was sort of emulating this original as posted by Hackmaster: Here is the base pattern: Its about 3/16" thick at the edge. I will turn it down...
Making a couple of threaded spindle backing plates for my lathe
  • 36,209
  • 17
When I sold my Atlas 10F24, I held on to my Bison 5” 3J, as it was fairly new. Naturally I needed to make a new backing plate to mount it onto the new lathe. The old plate was 1 1/2” X 8 while the new spindle is 2 1/4” X 8, so I needed new metal to do this. I recently purchased 2 backing plates from Busy Bee Tools. They are 8” semi raw castings. They are turned to clean off the rough cast surface and the center hole is 1” ID unthreaded. First I started by reading up on what could be the...

HTP Invertig 221 thermal over-load torture test. Real-world results. Very surprised !

  • 381
  • 10
So a FlyFishing piqued my curiosity as to what the "real world" thermal limits are on my Invertig 221. By "real world" I don't mean worst-case scenario, but rather what the machine would experience in an average shop. This was rather impromptu, so I don't have video footage (yet), but the data I'm presenting is factual. Ambient temperature: Picture showing machine at thermal overload: test piece to absorb a lot of heat: Machine showed 217A on the display. Not sure why not...
My slow speed diamond disc lapping machine, the beginning
  • 2,935
  • 61
I have all the materials. The idea is to mount this 90 RPM drive motor on the 1/2” aluminum plate. There will be an 8” lapping disc that will register on a hub on the wheel. Magnets will hold the disc to the plate. An adjustable tilt platen will allow for precise angles to grind high speed tool, carbide blades for scraping or brazed carbide cutting tools. The discs come in grits from 250 to 2,000 grit as far as I know. There will be an off switch and a forward and reverse switch. I found the...
Adding Zero-Clearance to cast iron bandsaw table
  • 3,082
  • 20
Hi all, I think this is my first post here - been lurking around for the last year or so. I have an Enco 360 bandsaw I picked up earlier this year. Two things quickly became evident: - It would benefit from a fence, which was a nice little project to make - The gap in the table for the blade is far too large for detail work or small parts. This saw seems to be designed for grunt work light commercial use, maybe on larger sheet metal or other parts where "whoops it got sucked into the...
My adventures with my RF-30
  • 3,585
  • 69
In this thread I will document my adventures in getting this mill from the dealer to up and running in my garage. I have another thread here that documents some of the early research and mills I looked at. I just bought an RF-30 clone. It was originally sold by Rutland Tool, which I remember as a local SoCal company in the 80's. I bought it at a machinery dealer in Pomona, Wheeler Machinery. Nice people, very reasonable to deal with. I was pleasantly surprised. I got the mill and a 5" Kurt...
Bridgeport CNC with Masso Controller/Clearpath
  • 22,611
  • 166
This is going to be my first CNC build and my First build log. I've decided that a build log on this forum might be a good idea for this project so the next guy to take on this project doesn't have to deal with the stupid stuff I'm already running into. This is my Masso Controller I will be using 3 Clearpath Stepper Killer servos model# CPM-SDSK-3432S-RLN They are a little over 6" long... almost 3.5" 1/2" shaft with a 3/16" keyway I will be using Teknic's IPC-5 75VDC power supply But...
