Thread: Engine turned ?

Do you mean circular polishing?

The book I have here says to do it with a small wire wheels like this QTY 2 - De-Carb Wire Brush Set - For Drill - Remove Carbon | ThatCable.com

in a drill press using valve grinding compound as polish... Moving over I think half and up half a circle each new line so the lines overlap.

Morrisman have a look at the video here https://www.woodworkforums.com/f22/no...sketch-163681/

It will explain much

Hi,

I was reading last night in a Southbend Drill press manual from the 50's the same thing but they said you could use wooden dowels or MS dowels with paste to achieve the desired effect.

Ben.

This web site is interesting , but he doesn't explain how it is done ?

Eamonn Keogh's Engine Turning Page

I Will have a look at that video when the library opens

Your right modern version Engine Turning on Torchmate R2.AVI - YouTube

The boxes though were Rose Engine Turned usually by a jeweler see the video link I put up in pervious post.

Some hints here:

Engine turning finish

and especially this one:

Engine Turning vs. Spotting

There are two things that are commonly referred to as engine turned - the polishing pattern seen on metal objects (like the back of fuel tankers). This is done with a circular pad (and some polishing compound) and can be done easily in a workshop with a felt pad and a drill press.

Then there is the stuff also known as ornamental turning. This is done with a special lathe but with various gearings on the tool and on the chuck that move the work in a cyclic pattern. This was a hobby activity for gentlemen in ages past, where they would decorate ivory, ebony and other items with incredible patterns. This example shows a continuous cut but some of the patterning is interrupted, or super-imposed on other patterns. Doesn't have to be just on a face either - it can be on the sides of a cylindrical or square object.

Hi Ben and Mike,
Thats the way i have seen it done on knives.

I posted some time back on the Ray Mac tool and cutter Grinder,Cant find the postings but I did the fancy turned finish to the metal ,
by making a small metal rod with a piece of metal 3/8th dia which I stuck a thin rubber pad and then glued abrasive paper and use a pillar drill to make the fancy work you are able to make complete rounds or half lap or play with it to make all kinds of patterns I have the photos in the library,but don't know how to now get them out, to show what I mean ,Hope this helps Morrisman the rubber is inportant as it allows for some movement,

Michael I beg to differ Ornamental Turning is alive and well right round the world today. I was a member of the Ornamental Turners Group of Australia am now a member of the Society Ornamental Turners in the UK. Yes still a bunch of old blokes enjoying them selves making the machines then experimenting with them. Oh International Ornamental Turners are the US mob.
Not so much playing about if you watch the video on my first link life is still full of OT/engine turned things we take for granted. Of course there are the masters of Horology?

Sorry.
"Gentlemen in ages past and the present"
Didn't mean to imply that no one did it these days.

One day I'd love to get a rose engine lathe for doing the cases of pocket watches and the dials. With the prices they fetch I figure I'm gonna have to make one myself. Which I'm quite excited about actually. It's on the list of things to do in the next 10 years.

Here's one to look at, I think it's fantastic:
Ornamental Rose Engine Lathe - antique Rose Engine description

George Daniel's has a very good write-up about them in 'Watchmaking', a very nice book. Roger Smith, who worked with Dr. Daniel's has some good video's on Youtube, this is just one of them.

Joe if interested pop out and see the Victorian OT guys Home - Peninsula Woodturners Guild

I saw this vid some time back, it was advertised at the end of another vid on utube. I've looked at their website and some of the watches they make are stunning. I would hate to see the price tag though.....
