Thread: Rocking Headstock

hi toni
Not quite sure exactly what you are after, but if you can post a piccy or a rough drawing, I could have a look at it for you.
Cheers

If you go back to the OTI site and look in the Photo Gallery, bottom of the second page, look at Fred's custom Rose Engine ("http://ornamentalturners.org/forum/gallery2.php?g2_page=2") and look at the first picture, Rose4, his headstock sits on a regular lathe bed and pivots on a pair of bearings that sit in the gap of the bed. It can be lifted off if not needed. At the top of his album is a link to his website ( http://ornamentalroseengine.com/rose/rose2/index.htm ) that has pictures of how the lathe is made. ( He also has free drawings of a small portable rose engine too.) You could take Freds bearing on the bed idea ( http://ornamentalroseengine.com/rose/rose2/linear1.php ) and blend it with Jon Magill's MDF headstock design. If you are going to buy Jon's Rosettes you could get the shaft parts at the same time and make your MDF headstock to fit the lathe you have. A couple of bearings and a length of bar stock for the pivot should be available local to you.

Hi Toni I haven't abandoned you I spoke to Alf regarding your problem and I am still waiting for the photo's it'll help design what you want, to fit your machine.

Is this to fit your OT lathe or your wood lathe ???? As your pm's and e-mail's to me indicated that you wanted it for your OT lathe.

Its not an overnight build Toni especially if you don't have equipment to turn metal parts such as the main shaft.

What size thread is your chuck??? Its best to have a shaft made thats the same this way you take your turned work still in the chuck and mount it on the Rocking head.

What QC Inspector has indicted on OTI's gallery is similar to what you need either lathe

The rocking headstock here is a Jet Mini which has had a conversion done on it.

You can see Geoff O'Loughlin's plans part 1 here and Part 2 here for the MDF Rose Engine it may be the quickest way to do what you want.

If Alf Jordon sent you up the CD with past newsletters of the OTGA on it then plans are also on it. Have a look at some of the equipment all different for different OT work.

Take a look at PsychoPig7's design its different again to even those we build at OTGA but still does the same thing. I believe this would be ideal for your set up.

HI Psycho. I have sent you a PM in regards to your lathe. Thanks for pointing it out Ray that is something I can use with my girl. I have read lots of plans but I just don't have the knowledge or the know how to build anything like that. Frustration I know but it is the truth with me so I have to aske for help.

Making my lathes into a rocking head stock I am not too keen on that. I could be wrong but would that be asking for trouble to get back into realignment all the time. I think that would be a problem plus my lathe if you see her in person she is beautiful and I don't want to dismantle her to set that up. I could not look at it happening. I know I am a wuzz but I waited a long time for her and I am going to look after her.
I want it for my OT lathe but she is both Ornamental and she is also a normal lathe too. She has both abilities.
bye Toni

The last statement Toni means with the steel you can produce the metal parts if it still has thread cutting ability. So we'll see you moving into the metal working section next .

Hi Ray not sure if it has thread cutting at all. I know it cuts a spiral like legacy.

Just a matter of changing the settings Toni

No Settings with her mine legacy is done with a bike sprocket and a bike chain and weights. Have look in photo here
thanks for all your help this is great

That's one of the joys of rose engines.

After you've built (or are half-way through building) one, you decide "I wish I'd thought to add..."

Unfortunately, most of the time it's not just a simple modification and usually means a complete rebuild. eg. when adding a rocking headstock you need to ensure that you don't change the axis of rotation (the points still need to kiss) and if the gearing involves lay shafts, you need to construct it so that those lay-shafts move with the headstock. (Which means added weight, which further means a more robust rocking mechanism... )

This is one of the reasons my rose engine is still only half bulit. It is constantly being stripped & redesigned. With luck, I'll have it finished just in time to turn some fancy roundels to go on my coffin.

Skew show us your Rose engine progress

At this stage, simply imagine an 800x600 sheet of marine ply with a few holes drilled into it, apparently at random. I stripped it down when we moved house and am taking advantage of it's "nakedness" to redesign the whole layout.

Yet again. Probably about the fifth time in as many years.

I thought not touching mine was bad enough for 6 months Skew 5 years and agree always a WIP.

I wouldn't feel so bad if I'd manage to get it completed enough to have turned even one single solitary rose on it before redesigning.

My mistake was to start googling after I'd first started building, just out of curiosity as to how others were approaching the task.

The first design was basically just a rocking headstock. Then came the rocking headstock with pistoning drive shaft. Which caused another major re-design about halfway through the build when I realised my original indexing system wouldn't work. Then I decided that I wanted the tool holder to be adjustable in a 5-axis system. (up/down, left/right, in/out and pivoting on the up/down & in/out planes)

And so the drama continues...

Skew I know you have wanted this for so long so i do hope you get it made before then so you can have a play
