Moronic things I did with my lathe today...

Like today is any different, right? :rolleyes: :biggrin:


I'd actually find this kind of funny if it didn't border on the "tragic" side. A little background first: I just moved a new mill in to my tiny "shop" which forced me to move all the machines out first. Now I'm in the process of setting my lathe back up. I positioned it just where I wanted it. Measured out from the wall to make sure it was parallel (OCD kind of thing :eek:), and pulled out my .0005" over 10" level to start the process of leveling it. I spent all yesterday afternoon getting the lathe close to level length-wise even though it's not real important I did have a "drop" from one end to the other (4') of over 1". Too whacked out for my tastes. So an afternoon of cutting aluminum shims of different thicknesses, ran out of material so resorted to cutting up some Red Bull cans. Okay, got it "close enough".

Today I wanted to tackle the important part, making sure that lathe is level forward & back (no twisties :)). Making shims again. Leveling this way was a major p.i.t.a. due to my own predilection to try and get it "perfect". For this the Red Bull shims were too thick so I dug up some .002" brass sheets. As you can imagine, using a tractor jack, and going back and forth from one end/side to the other, trying to get this kind of precision took me all day. In the end though, due to fatigue probably :p, I had it so it was maybe a half bubble mark difference between one end of the lathe and the other. Great! Time to fire it up to see how the belt is tracking...

Pushed on the lever to tighten the flat leather belt up (It's a "work bench" model) and to my absolute horror I find that I didn't leave enough room between the lathe and the wall to extend the drive pulley!!! :banghead: :(

I turned off the lights and walked away....

Back to it tomorrow.

Sounds like you did the right thing in the end. Sometimes it pays to sleep on it.

the wall behind my lathe is totally covered with nails holding mics calipers scribes everything
I had a piece in the four jaw out of balance and it is a bench mill
so i made a brace to go from the head to the wall to secure it
flipped the switch and shook everything off the wall

I feel ya, brother. Sometimes it's best to take the next day off, if you can, and rest your brain. You'll get it.

I can't say that it didn't cross my mind. :whistle: :biggrin:

Jumps, I hear you with the tools "off the wall". I usually do that with a set of Craftsman tools I have. It's a 120+ piece set in one of those black plastic cases and it's about 15 years old. Every now and then the plastic latch doesn't catch completely I go to pick it up, then I have to spend the next 45 minutes trying to find and get all the pieces back in the correct spots. Oh, to have a brain... :biggrin:

Ron,
Sounds like a beer drinking night, you might need some more shims anyway.

I'm not sure that would be safe. The world may want to keeps as all as far away from each other as possible. :biggrin: :lmao::lmao:

Uh... I thought this _WAS_ the club...

If you are looking for thing shims, I have had good luck with heavy duty aluminum foil. Thinner than alum cans, and readily available.

Just when you're sure that you thought things through... I have a nice heavy craftsman table saw that I decided just had to have some mobility so I mounted a set of wheels on to the legs just off the ground so I could lift up one side and roll it around like a wheel barrow. I was so proud of myself until I went to put it in its designated parking space and realized for it to fit with the table extentions where I wanted them that I had mounted the wheels on the wrong side. not a lathe story but still about use of space...

the Wall....is why I decided to move things around, and put the lathe out in the open.. ;) even though some inconvenience in other ways, its nice to know I can get to the motor, etc.
you should put your lathe on leveling bolts. :)


in keeping with the topic, my moronic thing today was while turning, just eyeballing, saying "it's still large enough not to worry".....yea....not a calibrated eyeball... i'm going to just make do...

Last night my parting tool stuck, seized the lathe and deformed my spacer. I just turned off the lights and went to the house. I feel your pain.

OK mine was cutting a 3/8 by 18 thread. Threads looks beautiful. I cut them lefthanded.

Just a thought. Can you install an adjustable idler pulley on the top or bottom side of the belt to take up the tension?
Might be easier than cutting into the wall.

Been there, done that....it was for a 5/8-18 thread for a drill chuck. I couldn't find a shaft anywhere for this beautifull 0-1/2" jacobs chuch that had been sitting in my drawer for years. It was my first time threading on my south bend 9 , the kind that you have to pick the gears and install the right pair in the gear box. I wa so proud of myself ....I figured out which gears to use and how to stop the lathe without disengaging the lead screw so as not to lose my place. The threads came out perfect...I was so happy. And then I went to thread it on the chuck....WTF. I must say it was good practice though. The second time around went smooth as silk. :)

And then there was the time I had to wrap 25 foot welding wire with shielding tape. I chucked up the wire in the lathe, put the lathe in real slow back gears and commenced to wrap shielding tape as the wire spun. Saved a lot of time but I don't think it was the safest way to do it. ;).

Bought a three tier crapsman rollaway, set it up without the casters on it. Wanted it so if someone broke in they would have to work at it to get it out of the garage if they wanted it that bad. All three boxes are bolted together, too. took the bottom drawer out, filled the base with pieces of steel plate, roughtly 200 lbs worth. Put the drawer back in. Started putting stuff in the lower drawers and middle box. Went to open the upper chest, the lid comes open about half way!!! OH S@#t!! It won't move, even trying to use a two weeler, it won't move! It's next to my 9" SBL on one side and another rollaway on the other that won't move neither. That was 7 years ago. To this day, I prop the lid open.:eek:

Ok so now all you have to do is make a L/H nut to suit. Problem sorted.

A nut wouldn't help. It was to screw into another part I had already threaded.

I feel for you Ron, Been there done it got the t shirt on occasions, Once marked out a fairly complex item, Checked my appropriate drills, Then drilled all the small dia holes with the large drill &all the big dia holes with the small drill, Pays to scribe next to the holes a "B" or "S" in some cases or just do not go into auto pilot, & pay attention &think what one is doing

Another time a buddy of mine & myself went to a machine auction, We wanted some nice equipment, & started bidding, In the excitement of the auction, we ended up bidding against each other! Everybody could not believe it, Real Laurel & Hardy vintage sketch "Another fine mess you got me into !"

I was trying to make one part fit on another part with very little clearance, but enough to let them rotate. I started to creep up on the finished size at .020 increments. The last cut needed .010" to put me at where I needed to be. I twisted the cross slide out the .010" and made my bore too big! I forgot that the cross slide doubles your cut diameter. I now have a sloppy fit to remind me to PAY ATTENTION.

Not all lathes, jp. But if you get used to using a 1" dial indicator to measure your tool movement, which isn't a bad idea on a questionable leadscrew lathe, it's always "Per-Side" so you will get used to it. It's an aid to accuracy to do that anyway. On any old lathe without a DRO, that's always been my crutch.

There is one advantage to getting older and having your memory start to go, not being able to remember all of the moronic things I've done on my lathe. I can't wait to get a bench top mill so I can double the moronic things I can't remember.

Don't feel bad, I just cut a bushing 3 thou too much in ID. Fortunately not a lot of time invested in the piece but, wanted to finish it tonight. I have no idea how I screwed it up. I either started from the wrong offset or, I bumped the crossfeed dial with my midsection...
