Hello Everyone
Its Wednesday and I am on a mini vacation. (just a few days off, for
no other reason then I have time, And that I need to use it.) ;-)
This cup was a nice way to spend my day. I turned the cup on the
Lathe, and then added the details.
I used Mike's "Gear indexing method" to space out the buttons. I also
used a spacer block off of the Legacy stops, to advance/space out the
rows the of buttons.
Over all it was a nice project to do today.
For newer members these methods have been covered in past LOM
writings/topic.
IN a nut shell. Mike's gear indexing method uses the Legacy's gears to
make the indexes, instead of using indexing plates.
(Mike's You tube video. https://www.youtube.com/watch?v=oHgzEKnON-o )
The method is pretty easy.
First figure the Circumference.
Diameter of the work piece X 3.14 then divide it by the router bit
dia, then divide that by 4 (the number of threads on the Acme screw)
this number will tell you the number of pitch you will need, Then you
need to use the gear charts to find a pitch you can get close to...
I use a 6" pitch for my gear indexing.(5 1/2" would have been better,
but 6" was the best I could make using my gears.) Then all that I
needed to do was put THE handle on the lead screw so it pointed
straight up. Every time I rotated the screw/gears one revolution, so
the handle was pointing up, I knew the part was at the proper indexing.
Once I made my first set/ring of buttons all the way around the dia. I
then used a 5/8" cut block to use as my spacing of the button rings.
all that really needs to be done is to use this spacer against the
acme screw locks to get the next placement of beads. (5/8" was the
best looking/spacing, 1/2" just looked wrong/to close ...)
I have No idea What kind of wood this is.
Its Very heavy and dense wood. it was part of a African carved statue
that I found in the garbage. The statue was painted black, to make it
look like Ebony,
I cut off the bottom of the base and use it to make this cup.
Any questions or comments are ,"As Always" welcome.
talk to you all more latter.
