Re: Wave Attachment
Hi C.G.Why have you twisted the top of the arm that holds the end of the long screw rod.and do you think this set up could be built onto a REVO.thanks to you and TIM.for a great idea, MAC.

Here are some of the original postings. Hello All, Here's the results of another invention for my Legacy Ornamental Mill. This is a traditional pattern done with the Holtzapffel Ornamental Lathe with the aid of an addition called an Atkinson Reciprocator. I'm calling my version the TK Reciprocator. Basically I linked the spindle to a crank mechanism that rocks the spindle back and forth. As the spindle rocks back and forth, the x axis lead screw is advancing the router creating the wave patterns. The amplitude of the wave and the pitch of the gears changes the design. In the near future, I'll post the plans if anyone is interested. The long wave was done with the 7.5 inch pitch gear, and the short wave was done with the 2 inch pitch gear. I used a barley twist bit. The diameters of the spindles are about 2. The amount of the amplitude is the same in each design, about an 1/8th inch. The depth of cut is about 1/16th of an inch deep. The waves are repeated 12 times around the spindles. Using this simple technique, a lot of variations can be made. The last couple of pictures show the face plate being used with the same technique as above. The first picture uses the magnate # 6051 side cutting round bit, and the last picture the magnate # 7976. By advancing the y axis towards me as the spindle is rocking back and forth a specific area is cleaned out. The bit was positioned about a half inch above the center of the faceplate. Notice the slight curve on the very inside of the blades. I think it's a really interesting effect. Also note that I did this example before I fixed my spindle. Notice the uneven cut. Hopefully the cut will be cleaner now. I'm really looking forward to working with this idea some more, I think that it has a huge potential! I also have a modification for the rotary table, but I'm still fabricating parts to make it work. That will be hopefully finished in about a month. Enjoy, -Tim Hang in there folks. I'm away from my machine until at least Wednesday. The Atkinson Reciprocator is a rare accessory for a rare machine. There are very few pictures of the original device. Here's a link that shows one. http://www.turners.org/images/Recip.gif. I have not seen any connected to a machine so I had to use my imagination. Not really a stretch when you realize you are simple turning the spindle back and forth by a small amount of degrees. My TK reciprocator was inspired by the Atkinson version. My version is much simpler, and allows infinite adjustment compared to the finite adjustment of the Atkinson version. I have not finished drawing the plan yet, or I would post the drawing. It really is very simple to make. Basically I'm placing a bar between the standard duplex gear and the standard index gear. The bar is mounted in a slide on the duplex gear that changes the amplitude of the wave. The slide is bolted to the duplex gear using the stock holes. The bar is connected to the slide using a Legacy quick release bracket. The other end of the bar is connected to the index with a pin and a magnet. The pin sits in the index holes, and the magnet keeps the bar in place while in motion. A spring is used to remove any backlash in the system when the rotation changes direction. By engaging the pitch gears to the index gear but not engaging the duplex gear to the index gear, I'm able to rotate the duplex gear independently using the x-axis crank. Since the bar links the
Re: Wave Attachment
Hi yes I did make a wave attachment for my revo i'll dig out the pics and post them later there on another computer Bill - Original Message - From: Tim Krause artmarb...@comcast.net To: legacy-ornamental-mills@googlegroups.com Sent: Wednesday, August 19, 2009 11:22 AM Subject: Re: Wave Attachment My two cents on the range. 1/8 to 1 is a huge wave depending on cutter diameter. It also depends on the pitch and the number of starts. In my arrangement you get four peaks per pitch travel. At two inches of wave travel and 6 of pitch travel, it's still a pretty radical wave that may not look attractive. I need to use it more often, but my need decreased after I built the tool. I'm going to be exploring the possibilities and redesigning the attachment later this winter. -Tim - Original Message - From: curt george curtgeo...@wowway.com To: legacy-ornamental-mills@googlegroups.com Sent: Tuesday, August 18, 2009 6:05 PM Subject: Re: Wave Attachment Hello MAC. I agree with Tim. Although I've never seen the Revo first hand, I do believe that the wave attachment could be made for this unit. Also to answer your question. Why have you twisted the top of the arm that holds the end of the long screw rod. To answer this question,I need to make two answers.One being, I all ready had a swivel joint and wanted to be able to use it, The only way I could make this joint work was to bend the holder to get the proper angle,The second part ,has to do with alignment of all the linkage, My holder needed to be offset to keep every thing running smooth. Since I've had some time to play with the wave attachment,(YEARS) I have modified my unit somewhat, I tried to take some of Tim's ideas, and make my unit more user friendly. I made the swivel joint simpler.Also My new modifications allow me to get a greater range of movement, (greater range of wave sizes.) and also they makes it easer for me to repeat those pitches.(years down the line.) I have to go. have a good night everyone, I will be back some time around 3:45am C.A.G. - Original Message - From: Tim Krause artmarb...@comcast.net To: legacy-ornamental-mills@googlegroups.com Sent: Tuesday, August 18, 2009 6:46 PM Subject: Re: Wave Attachment I believe Bill built a version for his Revo.
