12"x 36" lathe. Best way onto Stand?
Hi,
I recently bought a 12" x 36" lathe with stand. I unpacked the lathe and attempted to use a engine crane to place it on the stand. As I found out, unfortunately the legs of the engine crane would not pass under the lateral brace and even if it did, do to the center of gravity of the lift point (near the headstock), one of the legs needs to pass through the stand columns anyway. This is one of those generic 12x36 lathe stands as I'm sure you've seen. So I was reading Bill's recent lathe adventures and some one mentioned to twist the lathe lengthways, with the headstock toward the crane column, lower the lathe it on the floor, then recouple (so it doesn't twist back, lift and straddle it onto the stand length ways? . Is this the way to do it? I was tired when I gave up on it last night, but it seems like a resonable idea. With my mills I built my own stands, with the use of a pallet jack and crane in mind so this isn't an issue. But this is first heavy piece of gear I've got that came with a stand. When I got sick and tired of it last night I was certain that I would need to spend a couple hundred dollars on some steel and weld up a custom stand this weekend, but I would just as soon use the stand I paid for if possible. Any pointers? Thanks Mal |

(Or maybe I straddled the headstock, been a while, like 6 months.) Then lift the assembly. ABOUT 1/2". Lead ass friend can lift/push to keep it level, while you put it in place. Moved mine several times, (don't have access to electrical box, and a shop move). My shop crane is a HF, folding thing, upgraded with HF air powered cyl. Needs to be set short, or the legs don't fit. |

12"x 36" lathe. Best way onto Stand?
I mounted my 10x24 Enco by lifting it near the head, with the tailstock
end pointed away from the jack, aligned with the lift beam. I slid the tailstock around to balance it. With the lathe just off the floor, I move the whole works over to the wall so the left leg of the lift was against the wall. Raised the lathe, slide the stand under it, bolted the two together, then did final positioning. the overhang at the rear of the lathe leaves plenty of room for a lathe leg. This works only if you have sufficient working room to the left of the lathe. wrote: Hi, I recently bought a 12" x 36" lathe with stand.

This is one of those generic 12x36 lathe stands as I'm sure you've seen. It's pretty simple, if you don't mind building a little lumber-work. Build a gantry over the stand, using heavy lumber, and a a couple of laminated SYP 2x12's as the cross beam. If you have a stout enough ceiling, you can use it by running steel strapping over the truss elements. If not, you can still use the ceiling to hold the beam steady, and use single posts wedged in and screw-attached at the ends for upright support. Now, move the stand out of the way. Lift the lathe (a 12x36 isn't all that heavy) up into the air. I'd use two locking block'n'tackle rigs; one on each end. Lock it in place, and tie it off well. (you're about to do work under it) Slide the stand back into position, then lower the lathe onto it. Finally, disassemble your gantry -- at least the uprights. You may want to leave the beam for a future lift. We got my 14x40 Reed onto its stand that way. The whole process took maybe two hours, including building and demolishing the gantry. LLoyd You can avoid the lumber construction issues by using scaffolding which is pretty cheap to rent and rather useful to own. |

YMMV, but I've moved a few machines onto stands with a small chain hoist and lifting sling. Eg. http://www.harborfreight.com/cpi/cta...Itemnumber=996 Of course you need to find or make something above it to attach the hoist to (and it has to be something like a couple of feet higher).

That was my point with the scaffolding. Regular steel tube frame scaffolding is great for erecting a quick gantry setup. The regular aluma-plank deck planks are plenty strong to support a hoist, but you have to put a length of 2x4 across the top width wise (19") and put a rated lifting sling over that and around under the plank to a shackle to hang the hoist from. Two hang points evenly spaced is best since the planks aren't intended for high point loads. |
