Restoring an old powered hacksaw

Jul 29

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!

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"

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...

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

Jan 14

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

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...

Angle Plate Fixtures for Atlas Horizontal Milling Machine

2,815

I've been putting off another project for more than year and finally committed to getting started. In order to machine the base casting for the project, I decided to make some angle plate fixtures to bolt down to my Atlas Horizontal Milling Machine. The base casting needs to be flipped several times and spun due to the limited travel 6" x 9" on my Atlas. Here is the mockup renderings I made in Fusion 360 to plan my angle plate design: The pair of finished plates installed and ready for...

A Straddle Knurler for the Sherline Lathe

A Straddle Knurler for the Sherline Lathe The Sherline lathe is far more capable than most people know. I have explored the limits of this amazing lathe for the last 30 years and while I’m sure of what it can do, I am not so sure of what it can’t do because I’m still building tools for it. With the proper turning tools, it will take 0.120” off the diameter in mild steel or 0.200” in aluminum in a single roughing pass, then it will take off 0.0001” accurately using just the hand wheels. It...

Making a couple of threaded spindle backing plates for my lathe

36,701

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...

The fixture plates and clamps

May 04

Hi everyone, I just got started with this little weekend business of mine. I am interested in selling a line of fixture plates and what I call "low-profile" clamps to go along with them. This got started because I told myself that I would make my own fixture plate about a year ago when I needed to machine something that the vice would not really help out with, and I just never got around to it

. Then, the Corona hit and I was bored out of my mind and revisited my clamp idea for...

Norman Style QCTP

I have been using my Norman style QCTP and have sorted out the problems that came up through use. Instead of placing my findings at the end of the very long thread on making it I thought that it would be better to put everything in one place. First off you have to measure the distance from the top of the compound to center line on your lathe. 1 3/16" on my craftsman 12x36 lathe. Next you have to decide on the maximum size tool bits that you will be using. In my case I wanted to be able...

Spider Centering Test Indicator Holder

Mar 31

Posted this many years ago for my 1340GT, and built another for my ERL-1340 the other day. It uses a test indicator attached a Zero-Set which is normally used in mills for hole centering. Versions of the Zero-Set are on eBay and through Shar's for $20-30. The test indicator holder slides on two bars mounted to the lathe belt cover, so remains in the same position vertically relative to the stock in the spider. The tip of the test indicator is always in aliment and the Zero-Set/indicator...

Making A Rotary Broach, By Ulma Doctor

A couple years ago, I made a very quick and dirty rotary broach for a project i was working on in my normal job https://www.hobby-machinist.com/threads/shop-made-rotary-broach-down-and-dirty.48805/ it worked for the purpose it was intended, but i wanted to make an improved version. the new version , i envisioned was precise, robust, and economical. (i priced out a manufactured rotary broach similar to the size i'm constructing, it was over $500 USD) last week, i took up the gauntlet, to...

Radius ball turner

I've been wanting to make a ball turner for quite some time. Well, this past week I finally got a "round 2 it"! My first tool holder attempt caused me to say some things, that I'm glad my son didn't hear... ...but I managed to get it right the second attempt! I first tried mounting the base to the location where the compound rest normally occupies, but soon learned that I would not have enough room, between the radius turner and the lathes center line.... On the right side of the pic...

Hand Scraper Design

I'm monkeying around with making a scraper to repair the cross-slide on the 1440 and would appreciate some input from those that use them. I'm attempting to do this with materials that I have on-hand. The lathe crapped out at very a inconvenient time. I had to take a pass on a decent bit of side work because with the stick-slip, I messed up the first three pieces. So the budget is hurting. Richard sent me a copy of Keith Rucker's design. (Thanks Richard!) I have a couple of questions about...

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...

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:
