Build Your Own Metalworking Lathe From Scrap

So now that you have a furnace, what are you going to do with it? If you are an aspiring machining hobbyist, Dave Gingery's lathe is a very good start. If all you want is a small lathe, the cheap hobby imports might be a better go, but if you want to learn the full gamut of how to produce a accurate piece of shop machinery, building Dave's lathe will fill in much of the learning curve for the novice machinist.

Dave's Shop From Scrap series has been around for almost 40 years now and it still garners interest. I have a full set of all his books in paper, I also have many in my files that I have downloaded over the years. The problem is most are poor quality scans, and I would not repost them without redoing them to a more presentable state. Browsing some of my files recently I found a second copy of "# 2 The Metal Lathe" that was in reasonable shape. A little out of alignment and the picture res. is poor, but very clean and usable. If you haven't found a copy yet, this is one of the cleaner copies around.

A Small T & C Grinder Part 2

So here are the drawings and material list for this nice small T & C grinder. This would have been quicker done in a pdf. The problem is "Projects In Metal" was published on over sized paper and the two page drawings had to be stitched together from three scans. This would have been a problem for my low end pdf software.

Expand to max. before saving.

Hope someone finds inspiration in this plan. I have the original build manual for the Quorn. The problem is it is 59 MB and would take forever to upload on my disgustingly slow connection. Check out some of my other files below.

I have many other files on tool and cutter grinders, including other Quorn plans. Below is one folder with a selection of many of the files I have collected. See something you like? Message me and I may be able to post it. Not all files include measured plans.

A Small T & C Grinder Part 1

So as promised here is the first part of a very complete plan for a small tool and cutter grinder. Difficulty is in the medium range for the home machinist, (I would class the popular Quorn as advanced). Materials are mostly salvaged material. When I first saw it I recognized the motor right away, I have two of them, purchased many years ago from Princess Auto's surplus offerings.

Ya thats great, but where are the damned drawings? Ha, ha, check out the next post.

Interior Warmer Hack

So that killer cold continues, and taking a break from feeding my wood stove and reading, I figured I could do a couple of posts. Off and on for the last two weeks or so we have been breaking low temp. records that have stood for 100 years ( if my name was "Trump" I'd be saying "see no global warming" lol). A couple of mornings ago the temp. hit -46 and -52 with the wind chill. For the first time, my truck wouldn't start. I plugged the block heater in and set up my hacked interior warmer under the engine. It started within an hour.

I have never been crazy about interior warmers, back in 1981 I got an interior warmer from my dad, I don't know how long he had had it. It needed a mounting bracket and it spent most of its time in storage. 12 years ago I came across it and decided to mount it in a portable and adjustable stand. It has come in quite handy over the years. It comes in handy as a small space heater in the outdoor equipment shed, which is insulated, and the adjustable heater allows me to direct the heat where I want it, I often use it to warm up my yard tractor on these very cold days, and as it happens it fits nicely under my truck engine as well.

Here is the heater mounted in a stand of my own design and construction.

The heater tilt is adjustable, here in it's middle range. After many years of use it could use a new cord and some paint touch ups but otherwise good for another 40 years.

Here it is tilted up for use in warming things like engine oil pans.

Here is the stand I built with the heater removed. I had a large piece of light and shallow U channel. After careful measurements, I marked it out and cut it on my import metal bandsaw. I then drilled two 1/4" heater mounting holes, 4, 5/16" holes for the rubber feet, and two 3/8' holes for the adjustment locking knob. Next I did the bending and a paint job. That was it, ready to mount the heater.

"Aircraft Metal Work"

So here is an excellent book on aircraft metal work, and as would be expected a large section covers sheet metal work. This book was published by The US Government Printing Office in 1945 as a Navy Training Course.

In this book you will find 348 pages of great hands on instruction, covering most aspects and materials of aircraft fuselage production and repair methods. Check out the contents page below to see what is covered. It is a small djvu file but very clean and readable.

How To Make A Slip Roll Machine # 3

So here is the last of the Intermediate Technology Publications "Workshop Equipment" series. I have one more # 2 "How To Make A Treadle Operated Drill Press" . However the scan is of very poor quality (half pages cut off) and in my opinion it is an inferior design. I also did not upload #'s 8 and 9, I have searched, but been unable to find them.

So here is # 3 "How To Make A Slip Roll Machine". There are many plans around for this type of machine, I have posted plans for 2 or 3 other versions and I have a few more I will post in the future. This one is typical of the other plans in this series most of the materials are standard steel stock and a welder is necessary.

A Few Short Articles

Back in the 80's Fine Woodworking published a series of manuals titled "Fine Woodworking On". The series had titles like "Making And Modifying Machines" and "Woodworking Machines" they were all composed from articles in the first 10 years (1975-1985) of Fine Woodworking magazine. I will visit these again, at a later time.

Here are a couple of short articles and the cover picture of "Making And Modifying Machines". Remember this post "Scroll Saw On Steroids", Here is a picture from the cover that was not in the posted article. It is pretty clear from this picture, that I wasn't kidding when I said "on steroids". Check out the size of timber the author is cutting here, you would need a large, tough, band saw to handle a cut like this, and the length would be limited by the throat depth. With this beast and outboard supports, you could cut to shape the center of a 16'er if you so desired.

This article was originally published in the May 1980 FW magazine. It is a tongue-in-cheek look at tool steel production. The technical details are correct the scenario is hilarious, as is the illustration, LOL.

It seems D. Gingery thought the illustration was entertaining as well, and included it in the first page, of the second edition of, "The Charcoal Foundry".

The second article today comes from the March 1980 FW magazine. This article covers a very inexpensive alternative to a jointer. You can't do the face with this, but for perfect edge surfaces, this can be faster with a better finish than a jointer. I have seen this idea a few times before, the Shopsmith Mark V combination machine has sold a disc accessory like this, for it's machines, since back in the 1950's. It is certainly safer than just cutting square with the table saw or even using the jointer.

Edit: So I don't know where my head was when I called the Shopsmith Mark V a Woodsmith yesterday, so when I noticed that today I had to correct it. While I was at it I decided to post a page from the Shopsmith 2005 accessory catalog, where they sell this disc for their machines.

At $50 it is a heck of alot cheaper than buying a jointer. Even better, it's free if you have a small furnace to cast the disc in aluminum. You can finish it on a wood turning lathe if you do not have a metalworking lathe.

"Cutting Tools For Metal Machining"

Here is a book that will prove very useful for hobby machinists. No matter what sort of machines you have, none of them can perform up to the standards they were designed for, without proper tooling, properly ground.

"Cutting Tools For Metal Machining" was authored by Max Kurrein and F. C. Lea in 1940 and published by Charles Griffin and Company.

I did not clean up the djvu file, but the file is a reasonable scan with pages complete and reasonably well centered.

Pipe Carrier And Static Balancer

The first project plan here is also from "Arc Welding Projects" Volume III. This one is a pipe carrier, but not just a pipe carrier. This is another one I will be looking to build in the new year. I will be widening out the distance between the wheels. Why? Making it wider will allow me to use it for pulling heavy logs out of the woods, as well as moving pipe and steel sections out of storage, to the workshop area.

I have seen more complicated ones that couldn't do what this one will do.

The second project is a 1 page plan for a nice static balancer. My apologies I can't remember where I got it from, I found it printed off in one of my project binders. The plan is sized for balancing dirt bike wheels, so it may have come from one of the many motorcycle sites out there. It is sized for bike wheels, but of course you can balance anything that will fit inside the frame.

The plan is only one page but it is very complete, with full instructions. Dave Gingery built a smaller one in one of the Workshop Series books, but this is nicer and probably easier.

12-Ton Shop Press

Here is a nice clean 12-Ton Shop Press welding plan, from The James F. Lincoln Welding Foundation's "Arc Welding Projects" Volume III.

I currently have a smaller bench mounted 10 ton shop press. It is handy for smaller work and gets used often for bending, straightening, and pressing jobs. I have had occasions when a larger press would have come in handy. The plan has always been to build a larger 20 ton floor mounted press. To that end I acquired two 20 ton jacks, long time ago when the price was right. One for the press, and a second one for back-up.

Now that the steel I need is sitting in storage, I am looking at building the 20 toner in the coming year. The plan will be very close to the 12 ton plan below. I like this plan, it is overbuilt for 12 tons and I will beef it up again, for the 20 toner.

If your interested, there is nice complete step-by-step build instructions here, for building this tough looking little guy.

How To Make A Metal-Bending Machine # 10

So from Intermediate Technology Publications comes another of their Workshop Equipment titles. This one "How To Make A Metal-Bending Machine # 10" is the last of the paper copies I have. Like the other two, it cleaned up nice and is complete.

The first half of the manual shows you how to build the bender. The second half of the manual shows you how to build a steel wheel for a agricultural cart. Now your probably thinking "What is wrong with this "Bozo"? What am I going to do with an ox cart?" ha, ha, lol .

But of course you can bend up countless other shapes, for many different projects, with this bender.

A Forged Bear For My Future Gates

So when I first built this place I installed a couple of wood gates at the entrance, hung on two 8' X 8" drill pipes sunk into and filled with concrete. They served there purpose of keeping scroungers off the build site, while I was still living off site. Shortly after I moved in I left them unlocked one day, a strong wind blew up and pulled them off their hinges. Rather than reinstall them I brought them up to the house and installed them as a wind break and snow fence alongside the turn around area.

So as you can see in the picture above the posts are still there, waiting for a new set of gates. The plan is two bend up two large, shaped frames to which will be attached verticals every 6 or 8". Adornment will be in the form of forged wildlife shapes common to this area, attached to the verticals and peaking around corners. A nice idea but I am not getting any younger.

So below is a nice step-by-step plan for forging up a bears head, perfect for my gate idea, I have a number of other plans for forging other animal shapes. Mark Aspery is the author, a blacksmithing instructor, he forged this bear head while attending an instruction class at a school in North Carolina.
