I hesitated to post my lastest project as it is of limited interest (devotees of Ornamental Turning are as rare as rocking horse droppings) so it is on a couple of other more relevent forums (If you've read about this elsewhere, pass by, I won't be offended....)
Still I suppose as this is Madmodder & you need to be a few bob short of a quid to build one of these, perhaps this is the right place after all.
I've had an on & off interest in OT for years (currently on) and would like a Rose Engine to play with, BUT they cost 'muckle siller' as my late father in law would have said. So the only option is to make one. Here is the progress so far.

For the full SP on the project have a look here.

That is really interesting! I would like to see more about it.

ofc...

I for one am interested in this... not everything is about model engineering. Good job so far. Now... hows it gonna work?

Wow

That looks muckle complicated A wonderful bit of setting up and improvisation.

Thanks for the link.

That is a wonderous machine you are getting together there Mark.

I am sure, with your dedication, you will have it making fantastic patterns in no time.

It is one of those areas of engineering that has been made redundant by the use of CNC, but to me, the first time I ever saw a rose engine in operation, the precision they worked to and the decorative effects they produced ensured I was hooked for life.

It is only thru the dedication of people like yourself who keep this (very expensive and even harder to find machines) side of engineering alive.

I can't wait until you start producing things off it. I am sure you will amaze everyone on here with what it can do.

Good question... The whole headstock is free to rock (slightly!) against a spring. The mandrel is also free to move axially again against a spring. The actual rocking or 'pumping' movement is controlled by those curly things (called rosettes)on the mandrel which are held by the springs against a fixed rubbers. As the work on the mandrel rotates it will either rock or pump depending on the rosette, the work is cut by a rotating (or fixed if you are really skilled and have a good machine) tool mounted on a compound table.
See one in action here.

Bogs - thanks for the encouragement.
You are right in that it would be so much easier with CNC but for me there would be no fun in that.
Anyway, have you seen my shop? where would I put CNC machines? I'm still trying to figure out where to put Rosy, probably have to be on top of something else...
