hi mike!,
you might get some answers from the reply i was typing while
you were posting yours...i have done my calculations thinking that i need
to get my workpiece between the bed rails(currently a bit more than 11),
and i need the Y and Z axis' carriage to ride over the
I would think that you should increase depth rather than width.
Question is, how big of a turning are you wanting to do? My wood chuck
is only 9 wide at the rails. I can turn a 19.375 piece. All
accomplished by making it taller, not wider. I am only supposed to turn
11 but that just seems
hi curtis,
thanks for the input...i am thinking though that i will need
two gears...reason being that one gear would be bare and the other gear
would have the two washers on either side of it...so the progression would
be a bare gear on the lead screw(as originally intended), then
Hello Joe and everyone.
Since we are thinking out side the box. (so to speak) How about a high-bread
between the two ideas, your machine and Mikes higher concepts. just might be
able to work together. (of a mater of coarse things will have to be modified
you head stock a little, to make it
If you lowered the centres could you not lower the centre support as well to
achieve the larger dia
I did do as curtis suggested and lowered my centre and tail stock to achieve
larger dia work
Slop was not a problem it never is as long as you take it up by always turning
in the one direction
well, that concept would work with a machine that does not have a center
support...and not because of the vertical support, but for the brace that
goes front to back on the longer machines...and you would have to modify
the tailstock as well...and there can be no play in the chain drive if you
a sidebar question, but still pertains to this discussion...does anyone
have any info on the gears that legacy used?...were they custom made?...or
are they commercially available?...or were they made by legacy or an
outside vendor for legacy?...basically, can any of the stock gears still be
thanks tim...will do...i do have the gears i would need to do this mod, but
i would have to break up a set...i would rather buy the gears i need...joe

The short version is the gears where custom laser cut. Give them a call to see
if any of them are still available.

hey bill,
on a typical legacy, lowering the center brace would be very
easy to do...so i do agree with you...how much did you have to lower the
tailstock and headstock to achieve the 15 capacity?...and was there any
indexing problems after you did your mod?...in my case, i can't
mike,
i would be curious to know how much lateral stress an 8 addition
would put on the tailstock and headstock...it could be reinforced to avoid
that, but it would seem to be an issue...and although i do not have a
crane, we do have ceiling mounted hoists...LOL...but a harbor freight
I guess another questions would be, are you planning to do a full length
18 post?, got a crane? When I do that size I am usually working a
pedestal no higher than 48 inches. If that is where you are going, all
you have to do is have removable sections for the belly girth.

some general info...i am very fortunate to have a small metal shop within
my woodworking shop...although my equipment is on the light duty side(no
bridgeport miller,southbend lathe or doall bandsaw here), it is a
tremendous plus when upgrading or repairing a machine...with that being
said, i
If I remember correctly I lowered it about 6 inches ,
Once you start working on the larger dia stuff it puts quite a strain on the
headstock, tailstock bearings I would be working 2 steady rests in somewhere to
take a lot of the weight
I didn’t do any indexing with it but I don’t think it
good morning to all(at least it's morning for some of us!)...the swivel
bearing is an excellent idea, but due to it's overall size, it seems it
would take a bit of machining and major modification to the whole gear
carriage to make that happen...double checked the taper situation this
morning
Hello Joe. and Good morning to you as well. ;-)
I do not think that you need to make a set of gears to conpencate for you
wideiing your Machine. I belive all that you need to do is add one more gear
into the linkage, (think of it as a spacer so to speak.) When gears are in line
with each
and since we are on the subject of the gear carriage, here is something i
will throw out there and see if anyone has any suggestions...in
