Re: LMS 5000 bed extension
My lathe came without a hole. I thought that showed cheapness at its extreme. Anyway, I just drilled a hole in each one. A very small hole. Small enough that I think I risk little intrusion by swarf. Even then I can just look because any grease in the hole will stop any thing from entering. Then I use synthetic grease using a chainsaw grease gun to introduce grease. Takes very little.? But in actuality, considering the turning rate and the lack of much pressure on the actual bearing surface, once the surface is greased, it may not require greasing for a long time. Using this grease I can easily turn my lead screw with my thumb and forefinger, very very very little resistance.? Using white grease is a thicker kind of grease. It is a thicker grease and eventually it will start to get stiffer or harden up. If your lead screw turns very easily without any lube and then gets hard using grease then it's the grease. If it turns stiffly without anything then you need to fix that issue. I dont use oil because it just runs out and makes a mess.?

Re: LMS 5000 bed extension
All ya need is a coat of oil on the shafts . A lot like the old
lathes where the spindle ran in a coat of oil . There's also
several articles on line on converting a small grease gun to
dispense oil .

Re: Moving my "new" Grizzly G1006
If you go to "grizzly parts" and get to that page and enter g1006 for the model is has an exploded view and a parts list.
They have a replacement handwheel, part 401V2 ($35.40) which is plastic and seems to have replaced part 401 which is likely metal and likely the handwheel remaining on your machine.? If so, you could get two plastic ones to have a "matched set".? Or have one of each.? Or if the remaining one is already plastic, then just get the one.? Might be hard to find a metal replacement, but there likely is something, somewhere..
You will also need one part 436 ($8.95) which is the little handle that affixes to the handwheel.
If it were mine, I would get the replacement handwheel and handle (or perhaps two if that was what was needed to make everything match) to get the machine back to "normal" so it is in a better configuration if I ever wanted to sell it.
On large mills, I find myself using both handwheels, but the right one far more often.? I find myself using the left one when the table is moved pretty far right so that I am closer to where the cutting action is (to observe) instead of being far away at the far end of an extended table or having to reach way over to get to a handwheel not in easy reach.
If you can find or fashion a power feed attachment for the handle-less end, you might enjoy it.? Grizzly shows parts for it, but it seems you can a replacement the motor for $503 which sounds like a punishing price and I can't imagine what an entire assembly would cost - IF they had it for sale.? Grizzly shows the entire power feed assembly as discontinued which seems to be this part number:? P1126231 - *DISCD*POWER FEED ASSEMBLY AL-200S V1 Charles E. "Chuck" Kinzer

Just loosen the set screw and move your handle if needed, but you really don't need two on a mill this size.

Re: Moving my "new" Grizzly G1006
It is pretty common for powerfeed to replace one of the table cranks. I have a Clausing mill of a similar size and same thing, left handle replaced by powerfeed.
Agree I can see where a second handle might be nice to have but I've not yet found myself wishing I had a crank on both ends.

Re: LMS 5000 bed extension
You can buy a grease gun that takes oil.?
I have made a manifold oiler.
I used 1/8" copper tubing solder in a mill block for oil .? Use a pipe cleaner down to meter out the after filling milled oil cup

Re: Magnetic indicator base demagnetizing
Old steel or alloys (AlNiCo for example) magnets used on car,
bike or telephone magnetos, galvanometers, ...? were easily losing
their field strength when decoupled from their armatures or when
shocked or annealed. Modern ones e.g. Neodymium are far more
strong, they almost don't or, at least insignificantly do.
Consequently, from time to time or mandatorily if dismantled
these magnetic fossils were needing a re-magnetization that
nowadays can easily be done. It's a matter of Ampere x turns.
Here's a link that will make Jacques' life, otherwise for English
people googletrans is your friend !
This is only a piece of public information, not a how-to

Re: Moving my "new" Grizzly G1006
After doing a little more research this is probably a G1007 mill/drill that had the power feed on the left end. The hand crank is not required at both ends.

Re: Moving my "new" Grizzly G1006
You might try contacting Grizzly to see if they have the part and what it is for. Even though the mill is discontinued they may have some useful information. If you can't find the part could you make one?

Moving my "new" Grizzly G1006
Someone sent me this excellent article on how to disassemble and move one of these mills. (The rest of the stiff in hood website is interesting too).
This guy moved his mill twice and explains in detail how to take it apart. He even weighed the individual parts, which was very comforting.? Despite being well into geezerhood, I work out pretty regularly and I think I'll be able to pick up all the parts on this list. Also I have a come along and know how to use them. That's what he used to lift off the head and that sounds quite practical if I can find an overhead beam at the seller's factory.
?I have one question for you guys though. This mill is missing the left hand crank handle for the X-axis leadscrew. (Possibly removed at some point to fit a motor, which was sold to someone else at some point).? Do I actually need one? Mini-mills have never had more than one crank and I don't really understand the reason why big mills have two unless moving the table during some operations requires an enormous amount of force.
So should I keep my eyes open for another crank handle or does it matter??

Re: LMS 5000 bed extension
The oil cup is good if you can fit it.? The problem with zerks, as mentioned, is that fine metal particles will collect where the ball meets the body so every time you push some lube in you're also pushing the grit in.? Whether you wipe or not.? Get ones that have covers.
|
Re: LMS 5000 bed extension
Yes.? Using a "wick" will usually work out fine if only a scant amount of oil is needed to get the job done.? It is my guess that the clearances involved in the parts, in general, on these things is loose enough that it might be hard to get enough oil in with a wick.
It is pretty typical to use an oil cup for this sort of thing, but they can be too bulky for some locations.? One nice thing is that you can flip the lid and see if you are "low" on oil.? But if the clearances are quite loose, the oil may drain out pretty quickly.
A Zerk fitting can certainly be used for oil.? It is more compact and you can shove anything through it you want.? But it's good to wipe it clean first so you avoid shoving debris in with the lubricant.

Re: LMS 5000 bed extension
I think most people just drill them for push-in button oilers, so it would depend on the size of the oilers.? Could just drill a hole and oil through there, but that leaves the possibility of contamination from machining particles.

Re: Magnetic indicator base demagnetizing
Actually, use non-magnetic tools - there are things other than brass that are non-magnetic! I'm fond of getting a bag of popsicle sticks from a craft store & shaping them into useful tools. There are also a bunch of useful plastic tools made for working with adhesives.
