Re: Rotary Table and String Art
Hi Tim Why can't one hook up a Spirograph mechanism as a template on the Legacy? The stylus would have to be modified to work within the mechanism. Instead of the mechanism being mounted above the work it is mounted to one side. I don't know if the Legacy has enough play for a smooth operation. The center of the mechanism is at fixed distance from the rotary table center. The extent of the mechanism has to be within the dimensions of the work piece. What do you think?

Re: Rotary Table and String Art
Hay Tim instead of going all the way through the Rosetta, stop at the middle of the pattern and then go back to the starting point. Or start in the middle and work outwards, to get a pattern. gota run.

Re: Rotary Table and String Art
I'm still thinking moving the table would be easier than moving the router. This is how the geometric chuck works. Believe it or not, I just broke out an old spirograph toy to play. It would be awesome to be able to make the patterns in wood. Since I can make gears, I do think it's possible. Just need to look into how it has been done before. I don't think we need to reinvent the wheel too much. -Tim - Original Message - From: ronkir...@aol.com To: legacy-ornamental-mills@googlegroups.com Sent: Saturday, July 03, 2010 12:24 PM Subject: Re: Rotary Table and String Art Hi Tim What I was suggesting is take a spirograph mechanism and attach it to a pattern board mounted to the backside of the legacy like a template. Now mount a work piece between the rails on a work table it doesn't have to be the rotary table. Now in the standard spirograph set up the stator of the mechanism would be pinned to a piece of paper. Then one of the gears would be placed inside the stator with its teeth engaged with the stator teeth. Then a pen or pencil would be placed in one of the holes in the gear or rotor. As the rotor moves the pen traces out the desired curve on the paper mounted below it. Now lets set up an arm that is attached to the router housing. One end of the arm has a stylus mounted in it and performs the task of the pen. Now if one were to move the stylus like the pen the router will move and trace out the curve. Now one could mount a pencil in the router and see if the tracing on the work piece is the same as one where the set up is perform in the traditional manner. The tracing is perform the same except it is translated by the length of the arm. It is like a pantograph with a one to one ratio. One concern I have the spirograph mechanisms normally have plastic gears. I don't know if that will stand up against the amount of force needed to move the router. The placement of the spirograph mechanism has to be registered to where the tracing is to start on the work piece. I think this will work given the restrictions I mention above. I see where Legacy was using a intricate cut template ,which had a lot of curves and holes in it, to create a copy using the router. Well that's what I had in mind. I don't know if I am pushing the approach too far. Ron -- You received this message because you are subscribed to the Google Groups Legacy Ornamental Mills group.

Re: Rotary Table and String Art
I don't get the math either. I'm a knuckle dragger that understands the math after I figure what is going on in the real world. Then I can use the math to solves things faster in the future. I did the loop you are referring to using the A gear and standard gear set. The pen started on the right side of the rotary table (crank side) and traveled to the left side. The y axis was set at 2 closest to me. Here's a pic with the y axis set at 1/2 and 1. I'm just starting to see how to possibly control this to get an effective pattern. More later. If anyone else has been down this path, please speak up. -Tim - Original Message - From: cole andrews To: legacy-ornamental-mills@googlegroups.com Sent: Friday, July 02, 2010 8:24 PM Subject: Re: Rotary Table and String Art Are you kidding? nowhere near bored, this is what I was hoping for when I bought the rotary table.

I own the standard gears and the 2x and the .25 gears. maybe I just dont understand the math. On Fri, Jul 2, 2010 at 7:49 PM, Tim Krause artmarb...@comcast.net wrote: This is getting interesting. I did all of my original tests with the y axis at 0. As you offset the y-axis in the negative direction, or towards you, that teardrop shape gets smaller and starts to change into a wave. Controlling where they go is whole new problem. It would be really nice to be able to turn the 3 offset pattern 90º and repeat it all around the circle getting a chevron effect. I still think a template might be the better way to go. Granted you can't make the loop (teardrop shape) with a template. This further makes me think of mounting a french curve on the back as a template. Probably not rigid enough, but you get the idea. A template with curves that could be mounted at different angle to get a suitable curve. I could go one step further an make a captured template in a french curve shape. Fun stuff.

Re: Rotary Table and String Art
Good morning! Tim is correct about the wave attachment. But if you want to make some neat wavy Rosettes Bill , try just using the Legacy standard gears sets with the turn table. A 3 pitch or more will make a neat wave on the table. depending on where you set up the router, and when you stop the cut will give you a lot of possibilities.

Re: Rotary Table and String Art
Hi Curt, I remember seeing the technique you described in one of the Legacy magazines. I'll have to go look at that again. I noticed that the teardrop shape that is made is 2 times the pitch in diameter, but always a teardrop shape. Granted we can use only portions of the arcs if they are large. This is where I really wished a math Wiz like Rich or Ron could speak up and tell us what is mathematically occurring. I tried drawing the arc in my cad program and I cannot seem to get the geometry right. It would be nice to be able to predict the curve in cad. I'm guessing there is a name and formula for the arc. It's way beyond me to know the math. Anyway, using the 2 pitch gear I doodled this design. It's 8 in diameter. The router traveled from the left to the right side of the table. I then moved the router back to the start and made the opposite teardrop. Then I rotated the table 45º and made another teardrop and repeated until the pattern was done. I would think some neat patterns could be discovered if I owned the reduction gear. At the same token, I think the same arcs can be cut using a template off the back of the machine and rotating the table to specific degree increments. It could be the easiest way to create a diminishing sine wave that we were trying to get by attaching the reciprocator to the spindle. Next month I was going to introduce the group to offset turning on the rotary table. Is anyone else dabbling in this method? Maybe we can open up a new topic and talk about that too. -Tim - Original Message - From: curt george To: legacy-ornamental-mills@googlegroups.com Sent: Thursday, July 01, 2010 4:25 AM Subject: Re: Rotary Table and String Art Good morning!
