Re: ornamental turning on a rose engine lathe video
Hello Everyone.When trying to make more OT looking cuts with the Legacy, we have a few problems, as a matter of fact the Legacy's strongest point is also its weakest ONE, "the lead screw". Most OT machines do not use one.(but having said that,)I have had some good results with the Legacy and making OT type of cuts,doing some things somewhat differently then the normal router bits, type of cuts (things like slot cutters, side cutting,roughing end mills, diamond hole saws .. ) but at this time, I feel the biggest problem that I've been running into is the lack of a worm gear for the Legacy lead screw. The 5/8"-4 is a very hard pitch to make a worm gear for. (I've tried, with only poor results so far.) What I've been thinking of is something like a pendulum Z axis, where the cutter is on the center, and the Rosette is off of the side, hooked up to a worm gear &,the lead screw. (sorta like a backwards and upside down Rose lathe on top of the Legacy.) ;-) The pumping up and down action idea came form another time.and project that I tried, I still think it just might works for short / small spindles and face-plate work, This idea was to put a rosette on the head-stock after the head-stock and before the spindle.the single rosette will make a up and down movement of the cutter. This idea did not pan out for me. I was not able to control the weight of the movement. But I did have some good results with a spring loaded spindle, and a rosette pushing on the spring to make a pumping type of cut. This was a screwy idea but it did work (somewhat.) the spindle was supported by a spring at both ends, the rosette was hooked to the indexing gear, When the rosette hit the spindle it pushed everything down, and then it returned back up, making a weird up and down cut, that was not uniformed from end to end. (I've not done a lot with this attachment.as a matter of fact, I scraped the idea.) My profile follower and the "Wave attachment," have worked out well for me in the past, (at least I've had some success with these to attachments, although somewhat limited.)The concept is to move/ control the work piece rotation instead of the cutter's movement,simple pattern's, can be used over and over to make, more complex types of cuts. The biggest problem here is... trying to not make the spindle look to busy! Basically what I'm saying here is, I've been trying for a while, I can show a 1000 ways how not to do it. and only a few ways that have worked for me. But I'm not going give up yet. I'm having to much fun trying.Have a good night. C.A.G.

Curt and myself have been thinking about the options to create rose engines cuts for a very long time. So long that I bought a mdf rose engines myself to get on with actually doing the work!

Re: ornamental turning on a rose engine lathe video
Combining several ideas: Use a variation of Tim's wave attachment (https://groups.google.com/d/msg/legacy-ornamental-mills/gsFab9dTSr8/h15dZQFqwEMJ) Run the lever up to a plate on a jack-shaft instead of the leadscrew. Connect the jack-shaft to a chain-driven Z axis (no leadscrews on Z) You'll need a sprocket on the jack-shaft on top and another below, with a closed-loop chain, so it pulls up and down to minimize slop on Z. Mount the router parallel to the longitudinal axis (https://ornamentalmills.com/Bill_Bulkeley/revo_side_mount/index.html) No, I haven't built this, just combining ideas from previous posts. -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.

Re: ornamental turning on a rose engine lathe video
hey Curt!... not surprised you have thought of this mod in the past... from what I can tell, you seem to always have "Legacy" on your mind!... LOL!... anyway, I would think the "pumping" action of the z axis would be better if it was in-and-out, rather than up-and-down... an in-and-out motion would allow using side cutting bits, which also opens the door for using a lot of different router bits, as well as grinding your own, custom profiles... from what I have seen on videos, the rose engine lathes use this same technique... that is, cutting from the side... if you cut from the top(or 12 o'clock position), you are severely limiting yourself to the type of router bit you could use... unless you had some other idea in mind with the z axis going up and down... I would like to think that with all the talent in this group, something could possibly be designed and made that was functional, affordable(to a degree!...LOL!) and easily understandable... maybe not exactly like what a rose engine lathe could do, but close enough that it would expand what a Legacy could do... thanks... joe > -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.

Re: ornamental turning on a rose engine lathe video
okay, driving home last night(1 3/4 hours!), came to the conclusion that a long length of a "wave" pattern for the z axis is not going to work... it would work when doing spindles, but not when the z axis was stationary and indexed cuts were desired... and to consider having one set of "rosettes" set up when doing spindle work and another when the z axis is in one, set position is not ideally desired either, at least in my opinion... too many setups, brackets, etc. … although it might be a considerable option, if an all around setup cannot be designed and made... so it's back to the drawing board, as the saying goes... I think Mike's idea of pumping the Z axis is spot on and the easiest way to achieve this mod... the problem now is how to get it to work in perfect unison with the lead screw, with no back lash... always impressed with Mike's solutions and jigs, i'll be interested to see what he might come up with for this... no pressure Mike!, LOL!... later...
