Keith, I agree with scraping it near the headstock where you use it most. I would have done a check out near the tail stock just to check myself. When I scraped my Southbend I squared the cross slide to the bead much the way you did and then I put an indicator in the head stock and "trammed" a 180° arc spanning the full travel of the cross slide like you would on a Bridgeport vertical mill head to square it to the table. I marked a point on the cross slide and touched the same spot with the indicator after moving the cross slide. This gave me a test of square with the spindle and the head alignment.
Glad you are feeling a bit better, Keith. Im still working on my LeBlond 10" (Im Joe from the UK) and I may well use your advice on scraping in the ways and any other mating contacts that I have on my 1940's lathe. Will send pics when I have something interesting to show you. God speed your full recovery and thanks for all the good advice!
You have to show the final blueing or it didn't happen! lmao No reason you couldn't move the setup out to the end and see how it compares. Because your square was tipped .0003 as well you can add that value to the .0005 you measured putting you real close to your goal. Glad to see this thing finally getting ready to see some action!
Interesting comment on the reason for doing the work near the headstock. That was always the problem with lathes- if you wanted a 15' swing you needed to buy a massive machine and rarely had any use for most of it. Those Chinese 3 in1 units addressed that issue with a big swing on a short machine so you had more versatility in that area that was used 90% of the time without having that extra 10' of machine taking up space.
Your explanation why you do the measurements close to the headstock make sense. Anyways it would be interesting to see the same measurements with the saddle at different locations of the bed. I am just curious.
Just for curiosity, try setting the granite square up near the tailstock end of the lather and do the corss slide measurements at that end to see how much they are out on the better part of the ways.
dear Mr. Keith, I love seeing your videos really very instructive, especially for me that I am amateur. so could you answer me what the material on the tip of this scraper? grateful for the return. Greetings
On your final check, with the reference edge out three tenths, the measuring edge would be out the same three tenths at the same distance. Did you stir that into your consideration of the final measurement? Depending on how far across you take the final measurement, you would be approximately 0.0005 - 0.0003... or would it be plus? Excited to see progress on this machine again.
Could a lapping compound be used to help correct very small deviations I'm alignment especially finishing with an extremely fine conpound? I'm aware about abrasives being embedded in the metal, but would it be effective for helping to correct the saddle to fit parallel?
I like to check the cross slide directly against the spindle running the cross slide on the saddle against a 10" sine bar in a 4 jaw on the spindle, assuming the headstock was already aligned to the bed. But then I'm lazy and use Moglice under the saddle.
Agreed have done a Monarch model 62 with Moglice and one with Rolon also Leblond and 21" Colchester ,Moglice is the cats meow. I think moglic will out last turcite sure moves with less resistances then the turcite.
@@zedo5851 I did use Multifil on the bottom of the cross slide where the scraping was easiest - just 2 axis instead of 3 interdependent axis. Next lathe I'll do the same, assuming it needs work.
Hi Keith. Nice work. I also turcited my saddle after having spent over two years (not continuously!) scraping 0.010” wear out of my ways. I also scraped the spindle bearings. I am interested particularly in how you went about scraping the dovetail turcite to re-angle... did you scrape the middle out to make life easier? If my understanding is right, for every 0.001” you scrape off one side, have to drop the whole dovetail 0.0014” to get contact again, with constant consequences for the other side of the saddle. I didn’t have quite the same issues because my ways had underslung dovetails at the sides but what you’ve done must have been quite involved. Well done.
I was curious too about how high the Kingway contact roll was mating with the dovetail surface. Were rebuilding a SB heavy 10 now that just had its bed planed. Nice! So, Keith, when you gonna get that planer of yours going? :)
While I enjoy the series, but did I miss the moment when the guys actually told how(!) to scrape for alignment? That information is more valuable than for the fifth or sixth time explaining how the granite square works or why pull and not push.
Hello Keith Not to pick on you but you keep saying 10 thousands of a inch instead of a tenth. I do agree with working up on the headstock end to keep your machine square and most guys do not realize 99% of you work is less then 6" long even big long shafts with bearing journals are still short just that you are working on a different spot on the lathe .The one thing I was taught when I apprenticed back in 1972 was the machine is only as good as the guy using it.
People are equally confused when somebody says 'tenth'. Obviously, a 'tenth' is really 100 thousandths of an inch. A measurement of 5 'ten thousandths' is correct.....not 5 'tenths'....even though machinists have used the other lingo to describe ten thousandths of an inch.
..seems so strange to see a man using a hand tool to scrap a flat surface on a large precision metal working machine...before watching this I thought that maybe a very precise machine would be used to make a slightly less precise machine.....
Great video Keith! Thanks for sharing. Loved your appearance on TOT.👍

That's not a lathe. That's a dream come true...
Getting close now ... also good to see Lance again. He was a big help to me in the scraping class last November.

Really looking forward to seeing this baby working!!
I’m a big fan of your channel and TOT. Love you see you two collaborating. I don’t miss a video that you make.
Looking good Keith!
ATB, Robin
great to see "how it's done".Well explained and nice to learn .Thanks.
Great to see progress on the Model K. Won't be long till' chips are flying!
Interesting set up for checking alignment. Thanks for sharing Keith. All the best Mat
Great explanations as usual Keith. Loved seeing you on This Old Tony, how dare he do an Odds & Ends video 😂
Yes! Been missing this project!
I'm all set to attend the event in Texas on November 17th, see you there!
Very nice, Keith. Keep up the progress- you're getting closer! ----Aaron
Has he subscribed yet Keith? You spelled out the instructions so clearly on the phone...
@Ahmad Jaxxon So many spamming bots on YT at the moment....
Hey, nice to see this project moving a bit. I know you're a busy man and sick atm too so I look forward to these little gems. :-)
Excellent video Keith
good job Keith

Well my old Monarch was good when I got it, everything else I just work with the wear. :-) I think CNC machinists call it cutter compensation. lol

Fascinating ! Thank you Keith
Excellent video!
reminds me of scraping a 12 inch babbit bearing about 20 years ago. longest three days of my life lol.
That is going to be a great machine for you

I kn ok w I'm late to the show. But now scraping what you did. How is level across the bed ways.
Monarch 10EE? hopefully soon. thx Keith
Hi Keith,
That's one step closer to start making chips. :-)
Super interesting stuff.
Great job ! ⚙️🔩🔧⚒️ Great video 🎥 !! _ Congratulations! 👍 🇧🇷

We need a west coast class .wish I could afford to take it I really need to know as much as I can on scraping

So you can do the same thing on a mill saddle

I was wondering if you checked the level of the cross slide as compared to the ways both across and longitudinally?
Hi Keith. Nice work. I also turcited my saddle after having spent over two years (not continuously!) scraping 0.010” wear out of my ways. I also scraped the spindle bearings.

Nice work. I'm sure that can be a very tedious process.
Hows the oiling system coming along?
Keith dont you need a gage pin in the dovetail to measure while moving the kingway tool ??
I was curious too about how high the Kingway contact roll was mating with the dovetail surface. Were rebuilding a SB heavy 10 now that just had its bed planed. Nice! So, Keith, when you gonna get that planer of yours going? :)
Excuse an ignorant question - could a surface grinder have gotten the ways in tune with a lot less time and effort?

Молодец.
Is Turcite equal to ECTFE (EthyleneChloroTriFluoroEthylene)?
www.aetnaplastics.com/products/d/Turcite
Turcite is PTFE (polytetrafluoroethylene) resins with added fillers such as bronze, according to the internets.
You have the patience of a saint. I would just grease it and run it... But then, I'm not a machinist.

That should read "lathe", not "lather", "Cross", not 'corss".
Don't let it bother you too much. Most people who speak English don't know how to spell, and don't even seem to know it.
