Back when wolves were just getting used to mankind being part of the pack, I helped a gentleman restore one of his antique cars. While we worked, he let me try my hand at his English wheel. I wanted to take it home with me. He wouldn't let me no matter how much I grovelled and begged. In fact, he was most insistant that it stay right where it was. Anyway, I put that idea on hold and went back to my dollies & mini beating bags and other means of forming metal on a minimal budget (read as: broke a lot) - not all at the same time, of course.

So now, I'm working on really small stuff and keep going back to that wheel. I've never seen one small enough to be useful so I've been sketching one out in my head. Thus far, my mental sketch uses a 3-4" C-clamp for the frame. A flat upper roller can be made from 1" section of a roller from a torn down printer and attached through some magic to the fixed jaw. The round rollers would have to be made on a lathe (no biggie) from the same roller stock though I'm not sure about the radii to use. Anyway, the lower rollers would be attached to the moveable jaw with a temporary centering fork while it's being tightened.

Done right, this should work the same as a full sized English wheel but for Really Small Stuff. If no one's noticed that's a theme with me. :D

The electric hammer idea came from some turn of the century electric rock drill patents I came across. The basics were pretty simple, a massive solenoid driving a shaft with masonry drill head on the end and enough of a return spring that got the shaft back just in time to get slammed again. I guess they were effective though a patent doesn't tell how much use anyone actually got out of it.

Right off the top of my head, I can't think of a really practical use for such a device but it seems too cool a tool not to do something with on a slightly smaller scale and I figured it might be good for a conversation starter. There's nothing involved that should be awfully complex - solenoid, shaft (drill rod?), some way to switch the solenoid for single shot or repeated blows, bushings for the shaft, a return spring and something to put it all in.

Any thoughts on either ... aside from "Don't give up your day job."?

Best regards,

Kludge

Hi Kludge.
A small English Wheel is what I have dreamed of for years. It would have been a nice project making one :) So if anybody have plans let us know ;)

Hi Kludge,

On my periods of leave in the early 70's, I used to go around to a typical eccentric English inventors house, just to see what he was up to, and gather information. I would spend hours in his dingy little workshop.

Your bit about a solenoid operated hammer brought back memories of a thing he came up with. It was a self striking arc welding gun, that when in use wouldn't burn like a normal stick welder but a continual striking of an arc. Just touch the rod on and away you went. It welded very thin sheet to perfection, no blow holes at all. He used it to weld in new bottoms to rusted out bicycle carbide lamps.

Later it went onto the open market, but I think it was lost in time.
He actually gave me the prototype, a real lash up. I threw it away years ago, but I have remembered all the basic workings.

People like that have always fascinated me to the point of admiration. "Eccentric" is a good term but within that eccentricity is a genius that doesn't track with conventional thinking. In fact, they are often so far off the beaten path there is no name for where they are. But that's what makes them so cool - at least to me.

*drool*

Which means, of course, that you could sketch it out with a basic description so poor sinners like me could make them for ourselves? :D

*chuckling* ... he had a need and found a solution in the welder. I've got a solution but haven't quite figured out a need yet. I think we would have gotten along quite well.

Best regards,

Oh, my. Between sorting tools, putting "10 pounds of tomatoes in a five pound bag" in reorganizing the shop, trying to figure out how I wound up with so many watchmaker's gravers, and having totally insane ideas which I mention here for everyone's amusement (read as: "Haven't they locked him up yet?"), I also kinda sorta promised myself I'd learn some basic CAD stuff so have downloaded my usual overkill of a half dozen freebie packages. Right now, eMachine Shop is winning as to basic simplicity but I've not tried them all. Yet.

Presuming I actually manage to learn something other than how to make a crooked line, I hope to made a basic drawing of a shop-made one for consideration of those more in the know to punch holes in so I can improve it.

Stay tuned!

Best regards,

Kludge
 
Kludge,

You should learn my cad package, the one that I used for the sketch below.

A few details as far as I can remember.

It ran between 40 and 60 amps on the arc welder.
He used to swear by rods made by a company called Quasiarc, in my opinion the worst rods ever made, but it just might have been the price that attracted him. I think the rods were either 3/32" or 1/8" diameter. And they were held in a thumbscrew collet on the nose.
The central core was insulated from the outer windings and when the rod was touched on to the earthed workpiece, it completed the circuit to the solenoid.
With the solenoid energised, it pulled the core back, causing the arc to strike on the end of the rod. Because the circuit was then broken, the spring pushed the core forwards again, allowing the rod to make momentary contact and again making the circuit and so it went on, continually making and breaking, but because of the frequency of the fwds/ bwds motion the arc never had a chance to totally decay and so the very small, but much cooler bead run was laid down.
I cannot tell you exactly what the frequency of operation was, but I do remember the sound vividly. I would guesstimate around 250 to 350 cycles per minute.
There was an adjusting knob on the back of the central core, maybe that somehow controlled the spring tension, and so the frequency of operation.

Isn't it marvellous, being able to remember garbage like that, but forget what you had for breakfast this morning.

Heres a simple english wheel I made , a roller bearing for the top wheel and a spherical bearing for the bottom.
A piece of threaded rod to adjust the pressure.

Used it to shape these tanks and fenders.

I like that package better but I don't have a scanner. Yet. (I can't figure out where to put one so I may wind up with a multi-function printer.)

The central core was insulated from the outer windings and when the rod was touched on to the earthed workpiece, it completed the circuit to the solenoid. With the solenoid energised, it pulled the core back, causing the arc to strike on the end of the rod.

Ah, a think of beauty (design-wise speaking.) How often did the rod have to be repositioned due to consumption, or was the position of the whole solenoid setup moved forward as needed? In either case, it's almost like stitching the pieces together only with weld.

Isn't it marvellous, being able to remember garbage like that, but forget what you had for breakfast this morning.

Sometimes forgetting what breakfast was is a mercy. :)

I wonder if this would work with the microwelder. The low voltages & currents (12v from a computer power supply) make keeping an arc alive a rather delicate proposition. Oh, boy! Another gadget!

Thank you for the description, John,

I built this small English wheel a few years ago after seeing one similar somewhere on the Internet.
I used a bearing for the top roller and machined the bottom one. The frame is of 1" X3" rectangular tubbing. I'm sure it could be scaled down to any size that would fit your needs. I'll look and see if I can find the web site that gave me the idea.

This is a cool idea. What do you have the ball sitting in so it's free to turn? Also, do you use different diameter balls or just the one?

Used it to shape these tanks and fenders.

Ooooh, pretty. And a proper unguarded chain just like God intended. ;D

The first bike I had was a Harley 45 with a suicide clutch & tank shift. It had a kick starter and an open chain ... and was an absolute blast to ride. I rode a bunch of different bikes since but that wil always be my favorite.

Thanks for the ideas. I do appreciate them.

Best regards,

I was looking at some aluminum hobby 3" C-clamps after I posted about drawing one, looking for a clamp to use for my "model". I let them slide by because I couldn't think of a way to make them practical. This bearing idea at the end solves that nicely and the shape is almost the same.

How did you choose the radius for the roller? I've seen different ones used but never saw any sort of hint how to determine what's proper for a given application.

I have a couple different diameters but they are spherical, not with different crowns. thaey have ball bearings sleeved to fit inside which ride on a shaft which sits in the yoke.

Cool. I modified my mental sketch to use the same basic idea just in a much smaller scale. Much much smaller. Probably a 3-4" C-clamp machined from 1/2" aluminum for a frame kind of smaller.

Okay, that's not fair! That's two more forums that it's a moral imperative to join! When will it ever end? :big:

Seriously, thank you for them. I feel like a student (Ranger, are you taking this in? A 63 year old going back to school and you're a step or three ahead of the old fart!) but I love learning.

BEst regards,

Kludge

Have you thought about a palmnailer

Okay, I didn't see that coming - a practical use for the electric hammer. :eek: How did that happen? Won't Noelle be proud! :)

Seriously, thank you for the heads up. I doubt mine will have the same power but it does give me some ideas how to use it including making a frame kind of like a watchmaker's staking set for things like riveting and setting really small gears square on shafts etc. Okay, this is getting even more so ubercool.

I wonder how many different ways I can make one of these things ...

These people make simple but effective tools which you can use as reference and idea starters. Just scale down the designs.
http://www.lowbucktools.com/MM1.html

If you have access to "Street Rodder" magazine they've done an article on Low Bucks "Metal Machine" - November 2007 issue - or (although I haven't checked) you may find the article on their website

Let's see ... slightly enlarge & beef up the frame to 5/8" square ... mumble mumble ... mounting bolt and locating pin ... mumble mumble ... classicly clever design - glad I thought of it ... ;D

Thank you, Garry. It solves several problems in an elegantly simple way. I looked at Lowbuck's site and they've got some decidedly cool toys in general. I may ... ummm ... borrow a few other ideas later on. :)

I didn't see that article but I did come across one on the Y-block Ford engines. That brought back some good memories from the early 60s and a certain "mildly adjusted" 292 that lived in a certain 1957 unassuming grey Custom 300 4-door sleeper - basically a "daddy's car" on the outside but not under the hood.

Again, many thanks - both for the information and the memories I came across.

A place called www.metalmeet.com has a fair amount on the wheel. I seem to remember several designs and lots of ideas. Working with sheetmetal is their focus.

Hmmm ... Viggen ... a really sweet Swedish jet fighter. :)

Anyway, I looked at metalmeet and *sigh* ... it's yet another forum I absolutely must join. This "moral imperative" stuff is truly a burden but, as a more or less sentient being with a degree of understanding of the difference between right and maybe not so right, it is one I must bear ... which actually sounds like a really good tagline.

Getting back, they have a beginner's section and everything which is ubercool. And, from what I read in the description, they sound like another fun bunch of folks.

Many thanks, Viggen.

This month issue of The Home Shop Machinist magazine Sept/Oct 2008 issue. Has a very extensive article on the wheeling machine by Kent White of TinmanTech.
10 pages of history, design operation and the tooling. More than most will ever want to know about the wheeling machine! ;)
