Tim,
I think he wants a one start .20 pitch on a 1.5 dowel. I think this is
quite possible with a reversing gear modification. If the size of the
gears were offset one gear at 24 teeth and the other gear at 120 1:5
would be accomplished. Then a 1 inch standard gear pitch would become a
.20" and achieve the thread Dustin would need. What do you think?

You want to create a one and a half inch five start thread right? I hate to
disagree with Bill, but I do see the 1-1/2" -5 thread possible currently on
the legacy. Using the .25 reduction gear set and the "F" gear will give you
the 1-1/2" pitch. The 5 start you have to be clever and use the crank
handle method to rotate the stock to 5 different starts or 72ยบ. A while
back I posted a message regarding a new way to do spirals and that technique
would apply.
I know there are several members wanting to upgrade their manual equipment
to cnc. If you do this, please feel free to share.

Tim,
I wanted to chime in regarding not posting often. The only
disappointment that I have regarding the group is the difficulty
posting pictures, which has everything to do with google and nothing
to do with the talented members of this group. This certainly doesn't
keep me from posting when I have a question though.
The daily email from the group that I get in my inbox keeps me
informed on current topics, so I often feel caught up with the latest
happenings on the group. A lot of my lack of posting mirrors my actual
time woodworking, which is very infrequent anymore except for
commissioned projects or a special fun project I've been thinking
about. You're also correct in that I'm one of those second hand owners
of a legacy (1200).
As far as my interests go in the group, every post made here is
meaningful to me. My interests are:
1. Learning techniques
2. Seeing others' projects
3. Modifying the Legacy
4. CNC, or CNC-ifying the Legacy
Numbers 3 and 4 are the big directions that I want to head. I've got a
half built 3-axis CNC machine in my garage that I worked on as a
backup to my Carvewright when it breaks down during an important
project. I'm really interested in automating the Legacy and trying to
do my own Performance package CNC conversion to it with my existing
equipment. Other baby steps that I'd like to achieve would be
automating the x-axis to speed up making dowels (I thread 1 1/2"
dowels for erector set type furniture projects). I also have not
researched this, but I'd like to be able to cut an automated 1 1/2"-5
thread on the legacy. I have no idea if the gears support that, and I
suspect that they do not at this time and I'll have to wait for CNC
conversion.
Dustin
