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

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. On 1/21/2015 3:29

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
