Ron that is some Very nice work you have there!
The elliptical bowl is something that I have spend a lot of time on, over the
years.(sadly with little success .) Perhaps when I get some more time, I will
be able to get my Legacy oval jig working as I hoped for?
Please stay health Ron, I cant wait to see what you will come up with in the
future. ;-)

Hi CurtThe topic I was working on with Burnie was oval or elliptical bowls.He
was using his manual legacy with a template follower for a straight wall oval
bowl.
I was looking at doing it using segments which would save a lot of wood. The
problem is the segments are not the same as in a circular bowl at a givenring
level. The angle to cut segment ends at are not equal and vary within the ring.
With exception at the major and minor axes based on the segments bisecting the
axes. Burnie was considering graphing the given ellipse and measuring the
angles. I addressed calculating them using developed equations. The
determination would be for only one quadrant since the other quadrants would be
the same. Burnie and I had a lot of discussions about the legacy and improving
and increasing its capabilities. I miss his discussions as well.
I make all my bowls using segments. My bowls are about 14 inches at the largest
diameter and about 9 inches in depth. I use my Shopsmith to turn them. The
diameter and height prevents me from using the Legacy. I have considered making
the rings on the Legacy and assemble them and then turn the bowl on the
Shopsmith. However, I haven't tried it yet. Due to health issues I haven't been
in the shop much I have attach some pictures of my bowl in construction and
complete.

Hello RonThank you. Burnie and I had many conversions over the years, ( I do
miss him.) I have not had the pleasure of knowing Mr. Gold. (But I know Tim
would very much like to see that VB script you were talking about. ) The CNC
world is something right out of the Si-Fi comic books. Amazing stuff. and way
beyond my comprehension at this time.
Since you own a 1000 ex. I can explain how I made my Wave attachment, (with
pictures) If you want to make your own attachment for your Legacy. Its pretty
easy to do. Plus as I already stated, the cutting method is unique.Have a good
night.

Hi CurSoftware has been developed to produce sign waves on a circular column.
This software was developed by Mr. Gold in North Carolina. I don't recall his
first name. He worked with Bernie modifying his Legacy with roller bearings on
each axis to improve carriage movement. He also helped Bernie in upgrading his
Legacy to CNC. Bernie was a member and he passed away a few years ago. Mr Gold
sent me a picture of a column where sine wave was cut on a CNC machine using
his software. I produced a report a few years ago that provides the equations
and software code for the generation of sine waves, half circle, ellipticle,
zig zag or triangle and square wave patterns on circular, multisided or tapered
columns. I refer to wave forms along the column as strings of pearls. I also
produced modifications to the equations and software to provide the same
waveforms around either end or both ends of the column which I refer to as
bracelets. I also provide equations and software for spirals wave forms. I also
have an approach for curvilinear waveforms for the rotary table. All these are
for CNC machines. The software is in VB script. I don't have CNC machine. My
Legacy is the 1000ex. I don't have the capability to compile the VB script to
produce the required G code. I put the report on the shelf about 6 years ago. I
haven't yet but I will send a copy of the curvilinear wave report to Tim. We
work together on wave form generations using the rotory table.

Ron K

Keep on working with it Richard, you are doing a good job!
The wave attachment, is something that is uniquely OURS, that is the LOM
group's, No one else can easily make the same type of designs,
Ive had wood turners ask me how I made that? even Guys with OT machines can not
do a wave, THAT is Cool (in my book/ a feather in my cap, so to speak !) ;-)
Have a GREAT DAY.

Hi CurtI am nearly sure how I did it,, but will make sure later today. It
certainly wasn't just by moving one hole on/in the 40 hole alloy plate.Richard

Well Tim you are rightWhat I did was to keep my finger in place on the pin of
the TK ( pressing gently in one direction )The cut was done, by putting the
pin in the next hole to where it should have been.. I:E I made it make a
mistake like I did. All trial and error on my part. The question is ---shall I
be able to do it again ??Richard

That's something I have not seen. You might want to add a light return spring

Hi all you LOM expertsI am trying to do a long (approx ) 6 inch flute with the

If I change to the 2X gear I think it will only give me a four inch point to

impossible???Richard
