We've all seen the new lathe looks like it was ridden hard and put away wet... but how bad is it actually? The answer may surprise you...

Enjoy!

PATREON - This Tool Will Tell Me My Future

Those bearings are Uber expensive! I hope you find a way to fix the runout without a new set! I am getting 2 thou runout on the spindle but I need to find a way to precision grind the dings from the previous owner. I also have wear on the bed, your idea is awesome! Now I need a bigger surface plate! Talking about a long project… I am sure I will take at least 1 year to bring it up to standard… so many projects and so little time! Thanks for the schooling! I am so glad I joined your patreon!

Hopefully, the spindle slop can be corrected with a simple preload adjustment! The extruded aluminum 3-point sled was a great idea. Look forward to seeing your progress on this lathe!

Amazing explanations Brandon! Once you get this one squared away, you can come up to Indiana and fix my Clausing, been fighting a taper for a year and a half lol

Remember when I said something like "I don't know lathes but I know excited machinists?" Thank you for explaining exactly why that's an awesome lathe. I am unduly excited about its feature set. And boy do I know about projects. Good hunting, man, glad to be along for the ride!

L = N + 1, where L is anything worth having. This is Nobel material !

I'll probably be digging into the spindle first but it will take a while. Especially if I have to find the bearings. Same with the dings and whatnot too. I've had a toolpost grinder on my make list for a while! If you get a larger surface plate I'd recommend jumping to a 4ft so you can use it to also scrap the ways. the 3ft is good for the fixture but not quite long enough for the whole thing disassembled. Thanks for being here!

to be fair every 5th comment on the last video was wondering why the lathe was so special 😂 Thanks a lot, Mike. This is looking like a long one!

Great video mate. You demonstrated how an experienced Engineer gets that gut feeling that something doesn’t add up, so you devise different methods to check, and then critically analyse your method of measurement to confirm your didn’t create the weird data, which you did. Not a criticism. It was great to just share the experience because I saw the numbers and started scratching my head. Isn’t that lathe bed removable? For the amount of material removal you are going to attempt, perhaps a pro regrind is in order then scrape and lap in the final microns if needed. I know it may not be the most popular video topic but perhaps you could do a show on why these small errors compound, expand upon the math you showed with a more visual demonstration of what is wearing with a topographical graph of the data. I’m sure a lot of your viewers don’t have our math education, or a fitters’ education on the machine capabilities and the math they use. Even explaining how your analysis and problem solving process plays out. Maybe they are just here to watch the chips fly too but when you are taking on this degree of precision restoration I feel it deserves some drilling down into the detail.
