Restoring an old powered hacksaw
  • 6,854
  • 59
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"
  • 17,006
  • 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
  • 14,372
  • 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
  • 11,574
  • 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
  • 10,274
  • 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...

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

  • 706
  • 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...

MT3 1" Slitting Saw Arbor

  • 30
i started construction on a MT3 slitting saw arbor from materials in the shop. here is the slug of what i believe to be 12L14 mild steel. it was unmarked, but acted like 12L14 i have machined before. it's very nice to turn. the slug was a fraction over 1" in diameter and 7" long. i centerdrilled both ends. i turned the diameter on both ends down to .950". one for the drive dog, the other to make the taper turning operation quicker then i added the drive dog and offset the tailstock to...
