Restoring an old powered hacksaw
  • 8,722

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"
  • 19,059
  • 68
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

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
  • 13,698
  • 89
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
  • 11,440
  • 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...
Putting the ELS3 (Electronic Lead Screw ) on a LMS-3536 Lathe
  • 2,089

This project has a number of steps - I'll divide it into sections so you don't get overloaded!! Ever since I had my first machine shop in the 80's (Sheldon 10x36) I've had the bug to build or get an Electronic Lead Screw. Back then the tech was so "low" that I couldn't begin to afford or think of it. In 2012 I became aware of the Arduino and mcu's in general, and began tinkering... and the dream of my "Digital Gear Box" of the '80's came to life again! Back then all I could think about...
4th axis servo controlled rotary table build
  • 4,284

Hi everyone, I am getting ready to build a 4th axis for my CNC mill. I should be getting the rotary table in the mail in about a week. I will be posting pictures as I go along :). The rotary table is one from eBay. It is of the 8" variety. I believe the brand is CME. The servo and drive is from Leadshine and is 400w. Here are a couple pictures of the servo and drive:
Joel Miller Cnc Milling Machine

Original at http://jmillerid.com/wordpress/category/cnc-milling-machine/ CNC mill phase 1: planning Thursday, 9 June 2011 While I have understood the basics concept of CNC machining–and have utilized it in my work–I never fully appreciated how complex a system a CNC machine is until I set about designing and building one. There are many software and hardware layers are involved in the process, and each of these layers offers nearly endless options to choose from… CAM software, controller...
