Hey guys, in reply to several others that commented on my reply to Bodgia's thread, "New turner after some advice",I will try to clear up a couple comments made about my Tail Stock Steady. Also, when I replied to Bodgia's thread, it was tougue and cheek reply. Here in the states, we pretty much are at the mercy of imported stuff ourselves, and the mantra, Buy American. Well, it doesn't exist much anymore. Tucson Arizona started a program in the mid '80's, called "Tucson First", meaning if we wanted to purchase anything, look towards local shops and shop owner for your needs. Well, Tucson city people ordered the brochures and other 'Tucson First" advertisements from a firm in New York City...... Never figured that one out.
Ok, below is long winded, so you are warned.
The first is from Tongue Tied, Hi Jerry,
Have you thought about adding a retractable live centre to the Tail Stock Steady? Something that you could extend and use to position the bowl. Then you could retract the live centre back into the Tail Stock Steady, knowing that the bowl would be centred. Just a thought
.......
YessireeBob, TT. heheh In fact, this invention started as a live center with a threaded body that had a female threaded ring that screwed onto the live center body with a pair of wheels attached like what you saw in the video. The live center body was 1 3/4" od with a 2" long shell that had three bearings inside, one thrust, and 2 axial bearings, a ring cup nose as the center. The ring was was threaded to fit with 16 tpi to give a somewhat idea of a dimension as it was being adjusted, or screwed in or out, depending which direction you needed to go. I developed it in November, 2012, and all during 2013, I used my one prototype while also making 16 more. A disclosure; I'm not a machinist, but just a cabinet/furniture maker.
Anyway, during the day, I was making all these live centers, and in the late day and evening, was using prototype #1, getting a feel for the tool. As the year progressed, I was turning all types of wood forms, and then set up and remove these tenons. I would set up a jam chuck, mounted into my Chuck Plate,
IMG_0569.JPG
another tool I invented. The jam chuck is nothing more than a flat piece of MDF 3/4" thick with a few holes drilled into it to match 5 screws in my Chuck Plate as I didn't want to drill all 13. Since I made the CP also, I have several and have dedicated one for just tenon removal. So, drill the holes, making sure it fits the Chuck Plate, bring up the tailstock and live center, and turn a groove that fit's the rim of whatever form I'm going to remove the tenon from.
After it's fitted, I would remove the live center I was using, and mount my Live Center Steady in the tail stock, mount the form into the jam chuck, bring up the tailstock to the dimple on the tenon, tighten the tail stock into the form, and then turn the ring in the direction until it reached the pressure needed to hold the piece in place while I was turning off the tenon. When the tenon was completely gone, I would detail the bottoms with a few grooves, or whatever I chose to do, then sand it. It was done after sanding and was still between centers.
Well, that was how it was done for almost 12 months using the Live Center Steady. In the meantime, during the day, I was at a friends shop maching other live centers, refining them from issues I might have had the night before using the prototype I had. I gotta say, there weren't any issues . I suppose the execution of the first prototype was flawless, because all I did was get better at my machining experience.
During that early period of 2013, I started a patent application. Later on that.
In December 2013, I was done with 16 other Live Centers. There were about 10-11 parts needed to be made for the Live Center Steady, and the whole time I'm making all those parts, all I could think of was, How am I going to get the cost down to where I can sell them, and purchasers could afford them. That was spooky to say the least. Anyway, as I was packing up all those parts for the Live Center Steady, I slapped myself up side the head with an Ahha. moment. All that time making the jam chucks, rim chucks, friction plates, plugs, and any other of holding device to steady my forms, I realized that fitting them into the rims of the forms already centered them. I did not need a point from a live center. Duh!!!
Back to the drawing board. It took 2 weeks to make 14 of them, has only 3 parts to be manufactured, and best of all, it's now affordable. What you see Chas Thornhill in his video at youtube, Chas Thornhill, "Finish-Turning 20" Natural Edge Pecan Bowl", using is the finished product. That is what I'm marketing.
Joe, thanks for you comment, but as above, the center isn't needed if you fit the bowl rims to whatever holding device you choose to use. They will automatically be centered, and you just need to bring up the wheels, and remove the tenons.
Here is a form that I struggled withDSC05824.JPG. There really isn't a a true center I could find to use a stick type plug to bottom out on the inside, and there isn't a flat spot on the top to use a jam chuck. How I hollowed this was to go into a natural hole in the wood as my entry point, hollowed it, and then it took a while to figure it out. I made 4 of this type of form that I call a Natural Top Hollow Form. They are a challenge, but using your head, nothing is an obstacle.
This picture is a centerless ring I made. Needed 14 of them, and was a piece of cake to do. 20141031112908(9).jpg I've taken very thin bark and sapwood cuts, and made frames from it. What you can't see in the picture is my Chuck Plate mounted into my chuck. I do not like removing my chuck. Bad things happen when I do remove it, like dropping it or hitting my spindle threads and causing some grief. More later as I need to get to the post office ...
I've got to take care of some stuff, so will add more pictures later. ............ Jerry(in Tucson)
