Shopbuilt Lathes 2 (Continued)

Here is the rest of that great "Back-To-Basics" lathe plan. This plan was popular with the "WOOD" staff as well as at least 300 readers who built it, back when it was first published. I have noticed in recent years, in Canada anyway, that prices have increased dramatically on a decent lathe. And many people have learned that making your own, is a better option than some of the cheap imports available.

Reviving this older series of plans will hopefully provide ideas and energy, to those who want a decent lathe, but can't justify the funds required to purchase a decent one, at this time.

"WOOD" provides sources for a parts kit. These may no longer be available. Their are phone numbers, if the supplier still exists, they may still be available. Failing that, the trend is to order replacement parts from a preferred lathe dealer, and fit them to your shopbuilt lathe. If you can turn your own, or have a friend, or shop, turn them for you, even better.

"WOOD" contends that this lathe holds it's own against much higher priced commercial models, and that is saying alot, since it was before the cheap imports started flooding the market.







Hope there is lots of useful material here, for potential builders, and interested shop hermits, like myself.

Shopbuilt Lathes 2

I will be away from my computer for a period of time, so I figured I better get the rest of these lathe plans uploaded as promised.

"WOOD" magazine's "Back-To-Basics" shop lathe is a more complete plan than most, so I will upload it in two posts. I could have just uploaded it as a pdf, but Google drive can be a slow process, for my slow connection. All of you young folks out there can convert it to the format of your choice, faster than this old dinosaur.

Of the many plans for lathes I have seen over the years, this has always been the most appealing for me. I have no need for another lathe, but I may try my own version, possibly with a longer bed adopting some of Carlyle Lynch's ideas in the previous plan, just so I could play with some extra large turnings.

The plan was first published in "WOOD's" April 1987 magazine issue, and later included in WOOD's "Woodworking Tools You Can Make" published by Meredith Books.

The fellow posing with the lathe must be very tall. Proper lathe height puts the top of the tool rest at elbow height. My Rockwell/Delta is just right for me at 43". This lathe is also exactly 43".






Thats the first five pages. Five more in the next post.

Shopbuilt Lathes

So here are a couple of posts on shopbuilt lathes to go with all the turning articles and the few books I have posted. In my opinion one of the woodworking machines most suited for "shopbuilt" is the lathe. The design is pretty consistent across many different sizes. A mini-lathe is not much different from a lathe that can turn a 12' column between centers. As an example, Carlyle Lynches design for a large 8' between center lathe, (below) could just as easily be a 4' between center lathe, simply by shortening the bed.

Lathes tend to be top heavy, and since raw work is seldom perfectly centered, produce vibration. For these reasons its important for a solid  base mounting. Bolting the lathe to the floor or adding extra weight to the base helps.

Going through that "Shopbuilt Machines" Word doc. yesterday I came across David Doman's huge shopbuilt lathe. He got his ideas from two magazine articles, that have caught my attention as well, in the past. David B Doman's site is still active, so I only included the first page of his lathe below. If you would like to see more pictures and the build documentation, here is the link to his site.




So the two designs David refers to in has build have been widely distributed around the net. They were both published in the 80's in "Fine Woodworking" magazine and "Wood" magazine. They have also both appeared in their, post magazine, book publishings as well.

So to begin here is Carlyle Lynch's lathe design, published in Fine Woodworking in March 1986.




And now for something different. If your a welder or have a friend who is a welder and have access to some heavy steel sections, you can build this massive lathe. It might also help if you can turn, or have a friend turn up the massive 2 3/8" spindle. When you look at it, it doesn't look that massive, a credit to it's well designed dimensions. You can turn a 2' diameter hunk of raw hardwood into your hearts desire, with this beast. On the other hand if you want to do metal spinning, as in the small book I recently uploaded, this is just the lathe to do it on. Built by Jerry Blanchard, awesome beast.



As stated in the safety warning, don't take chances with your design, all adjustables should have positive locks, a lock that can vibrate loose, is not a lock at all. Like most machines, there is more than one way to get hurt operating a lathe, if it comes spinning out from between the centers the right way, it only takes once.

So I will upload the "Wood" magazine lathe design named, "Back-To-Basics" shop lathe, hopefully on Sunday, stay tuned. This is the lathe I would have built, if I hadn't found my top of the line (in the 60's) Rockwell/Delta.
