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...

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...

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.

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...

Inspired by @vtcnc and others, I've decided to make my next project a benchtop gear hobber!

Hi guys, here's another project that I wanted to share. This is a pic heavy post but wanted to share each process and op involved. The design came from the [mod edit for link] MakeItFromMetal website. I started out with a 1.5" x 2.5" x 6" piece of 1018 steel. The main block was then milled down flat and square to a finished size of 1.438"H x 2.438"W x 4.5" L. Then the front and sides were...

So another tool crossed off the 'To Do' list. Made a pair of machinist jacks, and wanted to post a few pics. I started by turning down some 1.250" diameter Heat Treated 4140 and made the screw/head pieces first. That way I could measure my thread pitch and make sure it was within proper 2A specs. Then I drilled the top of the heads to accept some .375" diameter bushings with a .0005"...

CNC Lathe Servo Spindle Upgrade

It's time to upgrade our CNC lathe spindle motor. This has been in the planning stage for the last year or so. When we did the controls retrofit on the machine a couple of years ago we lost what C axis capability we originally had. The lathe has live tooling and can do some light milling. A ''C'' axis is the spindle rotational axis and has the ability to index the spindle accurately, or...

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.

I started this about six months ago. I'd seen pictures of the Pine Grove (MLA-18). I decided I didn't want to spend quite that much, so after talking to Andy at Pine Grove, I had him send me the drawings and decided to try to build one out of materials I had on hand rather than use his beautiful casting kit. This is what I ended up with. Here's a video of it running.

With the proper turning tools, it will take 0.120” off the diameter in mild steel or 0.200” in aluminum...

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...

Machining operations often generate some plastic waste. Companies often collect this waste and try to use it by putting a small percentage of waste in with the virgin plastic. The problem is that the rate of generating scrap exceeds the ability to reuse it. Other companies simply write it off and it is a wasted opportunity.

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...

Easson 12B DRO lathe install with glass and SRA M-DRO magnetic scales
Mar 17

Just completed a Easson 12B DRO install on my ERL-1340, I opted for the stock glass scales for the X and Z0 axis for cost reasons, but wanted to use the 3rd input on the Easson 12B DRO head. When I previously looked into the use of magnetic scales a few years ago with the Easson DRO's I was told that they may not be compatible (at least the those from DRO Pros). At the time I went with the...

First Project - Upshur's Model Farm Engine

I am a retired software engineer and back a year ago I got the itch to learn how to precisely cut metal. You know, build something that I could actually touch and see. Around mid June I got delivery of my PM-1030V lathe with DRO and a bunch of tooling. This was followed in mid December of the arrival of a PM-727V mill, also with DRO, and more tooling. After dickering with setup, alignment and...

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...

Headstock Indexer

I needed a simple way to index my headstock for a chambering fixture I was building. I also wanted it out of the way so I could leave it in place and just use it when I needed it. Chain sprockets provided the answer. They're cheap and nearly any tooth count from 10 to 72 is available. I bought a 72 and a 50. They cover just about anything I would need .

I am trying to help a friend get a motor wired up and it has me stumped. The motor is 5hp single phase 240v 3420rpm TEFC with a centrifugal switch for a start capacitor. It was purchased surplus with no documentation and missing capacitor(s). Here is the tag: Grizzly has been no help. There are two red wires, two black wires, and one yellow wire coming out of the motor. R1 connects to...

Hand Scraper Design
Dec 05

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...

Do you remember the time when most of the things were made here, they were durable, repairable and they would last for a very long time? Do you remember the time when shop and other hands-on trades training were part of the school curriculum? And you also probably remember when all this deteriorated, was bought and moved oversees and centralized by mega corporations... And this is great for...

Difficult access carbide

Hello all. I need to turn into a location about 14mm long with a shoulder each end that prevents me using triangular or diamond shaped inserts. The material is Rockwell hardness of around 60 so normal tool steel won't do the job otherwise I could grind up something suitable. Specifically it is a running surface for needle rollers and the shoulder at each end is to contain the rollers...

Best Way to Mill an Angle?

I need to mill a 7º and 11º angle on the base of a round stand-off. While I could tilt the head of my mill, I'd rather not have to re-tram. What are other ways to hold a round piece in a vise at an angle for milling? This is what I have: This is what I need: Thanks in advance.

Turning very small aluminum rod

Nov 24
  • 8,726

I need to take an Al rod and turn it down to make two pieces about 100 thousandths diameter by 350 thousandths long. Tolerances need to be no better than 5 thousandths or so, that part's easy. I have some ~0.5" rod stock to start with. I'm guessing that if I just turn it down to that diameter it will flex quite a lot and I'll have some problems before I even get to 100 thousandths. Any...

303 Stainless Turning--Speeds/Feeds?

I'm turning a set of stand-offs for a vintage automotive luggage rack out of 303 SS. The stand-offs are 1.25" Diameter turned down to 0.625" diameter. I'm using an AXA-16 carbide holder with Terra Carbide 22-100-047 | TPG321 APC5T 60° Coated Triangle / Indexable Carbide Turning Insert. I'm getting decent results, but things seem happiest taking a 0.020" deep cut at the slowest turning and...

Morse taper drill bits...is there a market?

I bought some goodies from a guy yesterday and one thing I may go back for is a bucket of Morse taper drill bits. I have no idea at this point which taper and just from a quick look I think they were mostly larger sizes, probably from a local factory. Is there a market for these?

Sieg X2.7 (LMS 5500): X-Y axis locking problems

Greets to all! Have been using the mill off and on for some time now - VERY nice piece 'o kit (as the Brits would say). Recently I've been having an odd issue: when I tighten the X-axis locking screw (front of table) the Y-Axis locks up as well! Just took out all the X-Y gibs, cleaned and stoned, returned - Problem still persists. I would think with one axis locked, the other should move...
