South Bend reversing gear stuck

  • 3,827

I am restoring a South Bend 9 and work has stopped due to a stuck reversing gear. It loks like no maintenance was done since the machine was made in 1947. Everything but the final gear on the shaft has disassembled but that gear needs to be pressed off. A mechanic friend tried with his 20 ton press - dyidn't budge. I took it to a local machine shop and they stopped trying when the pressure was nearing a breaking point. I have to get this apart. It drives the entire gearbox and screw. I can't afford for it to fail. Any ideas would be greatly appreciated.

Cooler weather is coming, the kids are going back to school, and cottages are closing up. While it might be bittersweet to see summer coming to an end, it means that we settle back into a routine and start new projects. We decided to start the season with a fun demonstration on how to make a plastic ball using a tool that many people are unaware exists. We used a radius cutter and the lathe. When paired with a lathe, radius cutters are responsible for making concave or convex shapes. The process you see in our video is a great example of the art that can be produced by means of a skilled craftsman. Check out the link on our Plasti-Block™ YouTube Channel Plastic balls can be mass manufactured in many ways, but are primarily made by the process of injection molding into dyes. Take a look at this video of table tennis balls being mass produced in a factory. Check out our blog for this and other interesting articles: https://www.plastiblocks.com/latestnews

Scraping in all bearing surfaces on my Wards/Logan 10"

  • 5,931
  • 61
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 compound and cross slide. But I decided to tackle a far larger project. I've taken Richard King's class twice now (and I'm about to help out with a third) but I know full well there is no way to really learn something without actually doing it (and even better, trying to explain what you're doing to others). So, despite my old Wards/Logan being in perfectly (well ... "acceptably") useable shape to begin with, I decided to scrape in the bed ways, headstock, saddle, and tailstock. I rationalized that...

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 few industries, but for a lot of small shop and inventors, makers and hobbyists, there is a real need in local distributed manufacturing.

Home-made CNC lathe using servos

This is a thread about CNC Lathe I recently built. This is my first CNC machine, and obviously, I’m not a CNC guru. Being an engineer, I prefer more practical ways of making things rather than R&D approach with investing plenty of time, money and energy. This is also why I use simple and robust ideas instead of diving deep into unique ones and solving the problems just created. I started with Atlas lathe bed I bought on ebay. This bed has pretty wide (1-1/2”) flat ways, so one can easily put the linear bearing rails on it. To be continued with Drives and Tooling.

Hard Core Recycling - making blocks for machining
  • 2,401
  • 10
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. The same injection molding equipment we use to manufacture plastic blocks from virgin pallets that many of you now use, we manufacture 100% pre- or post-consumer plastic and transform it into finished goods with excellent material properties and aesthetics. To read a bit more about what we do, please enjoy this article: Hard core recycling. And to see our equipment, the first video is now available, few more are coming in few days: The Factory of the Future Transforming Plastic Waste into a Plastic Resource - This video shows a bit of the equipment and why it is really a big deal. I hope you find our cause worth discussing and sharing. We are looking for...

The Plasti-Block YouTube Channel Is Now Live! Following a number of inquiries about our plastics including what type to choose and how to use them, we decided it would be beneficial to create an information hub from which we can share our knowledge and experience with you. We have chosen to start a YouTube channel as videos are an excellent way to show, in detail, the many aspects of machining plastics that you may not have previously known or considered. While text and pictures have their own advantages, videos allow you to focus on the nuances in a way that these other forms cannot accurately convey. Our YouTube channel is aimed at everyone. We uploaded first 4 very short and very basic videos. The plan is to create videos from how-to and tutorials to safety and best practices. We aim to add video content to our channel on a weekly basis. I really hope that you’d be interested to give us a feedback/suggestions/provocations for topics about machining plastic, as it is vital in...
An Amazing Butterfly! - great hobby project

This week’s Alternative Tuesday segment from the Acutabove Woodworking channel features a project An Amazing Butterfly! Our Plasti-Block™ ABS blocks are perfect for this applications because butterflies are beautiful and colorful – something they and our ABS blocks have in common! By using our colored blocks, Ken (and everyone else!) doesn’t have to worry about fading colors or poor blends, he just has to worry about doing what he does best: create. In making the butterfly, Ken used tools including a drill press, chisel, scroll saw, and heat gun. He also used other ‘tools’ to make this project a success; such as imagination, ingenuity, and a will to make it work. The end result of all these tools is a product that he can be proud of. If you decide to give this a whirl, you may be interested in some of our bundles as they are the perfect starter kits with a variety of different shapes and colors.

How To Fabricate Plastic Vise Jaws

This week’s Alternative Tuesday segment from the Acutabove Woodworking channel features a project to fabricate Vise Jaws! Every shop has an old steel vise or three. Many maker and hobby projects are held in a vise during operations such as cutting, sanding, gluing, or assembly. Sometimes the metal jaws on this vise are a bit too rough for the parts it holds causing scoring, indentations, and/or distortion. To solve this problem, a softer material than metal should be used. In this short video, Ken uses a table saw and a drill press to show you how to make vise jaws out of ABS plastic to protect your delicate parts. It is a very simple and practical project, and plastic vise jaws can even be custom-shaped to enable the perfect fit for your projects parts.

Machining Kazoo Project & Classical Music

Good news everyone! This week’s Alternative Tuesday segment from the Acutabove Woodworking channel features a project to machine a Canadian-themed kazoo! Ken turned some of our red and white ABS blocks into something awesome! What’s a Kazoo I hear you ask? A kazoo is a musical instrument that requires the operator to hum, not blow. By humming, a "buzzing" sound is created thanks to internal vibrations - causing a rather unique sound. While the exact origins of this instrument are not certain, it is rumored to have originated in the USA in 1840. In this short video, Ken uses a lathe and scroll saw to shape a fully functional kazoo with a demonstration at the end. If you love experimenting with making new things, this is the perfect hobby project to whet your appetite.

Toaster - a conversation starter

  • 1,266

Toaster is a great conversation starter about materials usage, resource management and sustainability. We wrote a short article to start the dialogue. (https://www.plastiblocks.com/single-post/2018/08/10/Toaster---a-conversation-starter) It is so sad that majority of people who have skills don't bother repairing slightly broken, old appliances. And people who don't have skills - have no one to help because repair shops are almost extinct. I hope you can participate in the discussion we started on our blog by commenting there or here and maybe share any repair projects of house hold stuff to encourage others to do so as well.

Power Z Conversion For PM45

  • 1,802
  • 25
I have an early model PM 45 mill that has the manual hand crank for Z elevation. Since I just reorganized my shop and a toolbox is placed nearby, I'm going to attempt to convert it to powered elevation using a heavy duty gear motor that I've had for a long while. I'm not 100% sure this will work to my satisfaction. The odds are maybe 70%... We'll see. I'll outline the design considerations as we go. Here's some pictures and explanations... Here's the mill with crank handle removed. I put a wrench on the shaft flat and roughly measured the torque needed to raise the head. Holding the wrench about 1 foot (little less actually) from the point of rotation, I measured about 8-10 lbs to move it. This was measured by setting weights on the wrench which is a little inaccurate. Anyhow, I'm assuming it needs 10 ft.lbs to keep it in motion. Here's a gear motor purchased at a surplus shop that I've had laying around for years. This motor is used in mobile-home campers to...

Finally picked up a slotter attachment that I have been looking for. Probably paid a bit much, but it's practically new. Stripped it and cleaned out the old gunk. Back together already, quickest rebuild yet. Missing one oil cap and the arbor, but I have a print for the arbor. All I did was clean it. Jason
