Monarch Lathe Restoration - Part 17 Scraping Turcite on a Cross Slide Bottom

Continuing with the Monarch 16" Model K Lathe Restoration, we are to the point of scraping the turcite applied to bottom of the cross slide to match the scraped saddle on the lathe. We discuss the process being done and go through the process of bringing the part into spec with good contact using a hand scraper.

nice to see a real resto rebuild not just the usual clean and paint

[@Hoaxer51]

Whenever I hear or read about a video for scraping, I just know it’s going to be very boring. But somehow you always make your scraping videos interesting, I guess it’s because you teach as you’re doing it and when you’re learning something you just become more involved in the process. Thanks for making this an interesting video and keep them coming!

[@AttilaAsztalos]

Or, you know, it's just _boring_. Sorry but you'll never convince me that voluntarily scratching up a surface is an improvement over a shiny, machined-flat one.

[@alasdairdavidgray7316]

Good to see your progress Kieth.

[@SteveSummers]

Hope to get a chance to work some Turcite soon. Never had a chance to use any of it. Could use it on my small T&C grinder saddle. Thanks for the video Keith

[@dananelson3534]

Not that I'm a judge, but you're scrapping skills get better all the time. Thanks for sharing Keith.

The best part of waking up!

[@WillyBemis]

Thank you Keith!

[@glennmoreland6457]

It's looking like a nice, satisfying job is that Keith...

[@infoanorexic]

I've had the cross slide apart on the Mueller, and I was rather dismayed to find out that it had been milled. It also tightens up as you approach having it fully dialed it. So far I've been able to work with it, provided I use a dial indicator to read movement, rather than trusting the dials. I keep reminding myself that the lathe is over a century old, and that there are ways to work around it's current wear issues, but I'm also aware that the gib is adjusted as far in as it will go. One of these days, it is going to need something put back where it was milled, and the dovetails corrected. Even with seeing how it is all done, I can't say I'm looking forward to it. Maybe by the time you get the 10EE restored, I'll have seen enough to be able to approach the task without the degree of uncertainty that I've got now.

[@rickbrandt9559]

Still here supporting..

[@Bob_Adkins]

When both your surfaces are scraped or ground flat, you don't have to scrape in the Turcite. Only when you can't grind or scrape the side the Turcite is applied to do you need to scrape it in. Even then, it's not as critical to get it finely scraped. It wears in very quickly at first, then becomes nearly as durable as iron.

[@johnmav8309]

Thank you!

[@MaturePatriot]

Very educational.

[@timmallard5360]

I've been messing around with the same ink! Works pretty good. Mineral Spirits in a eye dropper bottle helped thin it.

[@bcbloc02]

@@gurumaanu94 I am not the one to ask about CNC I hardly know anything about them.

[@crockteerden4023]

You should relieve the center a little to prevent “rocking”. The same on the positive dovetail

[@bradlilly8603]

I'm interested to see how the turkite holds up, it really looks soft.

[@LikeFactoryMade]

I am tempted in doing the same operation with my lathe cross slide. After grinding the fixed mating part, about 0.3mm were removed, so I am thinking about adding some turcite to get it at the same height. I wonder how this behaves in time, if there is a higher risk to get chips embedded into the soft turcite then rubbing and scratching the bottom surface. I would be grateful for anyone thoughts or experience on this matter.

[@Meatlips527]

What kind of wear will you get out of turcite? Does it wear down faster?

[@vajake1]

i did not know that you had to "stone" Turkite between scraping cycles! I should have guessed that it is necessary.

[@glennedward2201]

How would you recommend bluing a 58” table on a bed mill? I’ve got turcite on the saddle top and not the actual table and with the table weighing in upwards of 600 plus pounds I cannot conveniently put it on and take it off or flip it over to blue it. The approach I thought to blue the turcite and use a large granite block but the blue soaks in the turcite. It kind of worked ok where it was slightly wet right before it dried fully but I’m not certain it’s a reliable method.

[@poozandweeez]

scared the crap outta me with that razor blade haha brought back painful memories lol

[@FredMiller]

I understand that some companies are now selling their new lathes with turcite ways. They are long lasting and can be re-scraped or replaced if necessary.

[@johnferguson7235]

Have you also filleted a finger? I sliced the outside of my left index finger right down to the bone one time. There is no way to forget the feel of the razor slipping and then looking down at the bone inside your finger. I wrapped it up tight with some tape, to slow the blood flowing, and made a quick trip to the Emergency Room for 20 stitches. Now, I always wear gloves when I'm using a razor knife; don't want to repeat that mistake.

[@nakedanimegirlspls]

I feel the same way about table saws.

[@timambrass3521]

Why brother with the gib side? Isn't there a gap between the cross slide and the gib? What am I missing here?

[@darkwinter6028]

I pity the fool who doesn’t watch Tom Lipton over at Ox Tools! 😎

[@jeraldware1518]

What is the objective , to flaten? Are you concerned with the height and matching thevheight of feed screw?

[@tjofmaine1]

Keeping the swarf off the ways must be doubly important with turcite

[@rubarb0406]

Keith, can a person use JB Weld to glue down the Rulon or Turcite? Two hundred bucks for the recommended glue is excessive!

[@CathyInBlue]

I wonder if a matte black dye were used, instead of a prussian blue, if it would be possible to use a computer controlled laser cutter with computer vision, to just zap those black/blue marks with the laser to vaporize just a little bit of material automaticly, no more hand scraping. Just maybe stone the surface and clean it and take it back to the application and run it over the mating surface again and just put it back in the laser cutter and tell the computer to run the "scraping" program again. Surely a proper laser cutter would have the power to vaporize small bits of cast iron.

[@godfreypoon5148]

That would spoil all the fun!

[@CathyInBlue]

@@godfreypoon5148 I want to say that you have an odd definition of fun, but I know his is a channel full of manual machinists who would probably enjoy the process of manually scraping in turcite dove tails. I'm prolly one of them.

[@tehsimo]

How can such a soft material work in this application?

[@dolvaran]

Nothing for it to abrade against on the other surface, I guess.

[@crockteerden4023]

It works amazingly well. It will last for years: it becomes very slippery with oil.

[@MaturePatriot]

It should float on a layer of oil in a well maintained lathe!

[@hmshopfix6283]

I am wondering the same thing, but it IS widely used so there must be something to it.

Like Teflon non stick and slippery.

[@artmckay6704]

I took a bunch of screenshots, blew them up, and I cannot read the label on that printers ink. Can you please pass along what brand and type of ink that was? Thank you! :)

[@neptun733]

Hi Keith, I'w been following you for a year and a half now and I think I have learned enough to start working now, I have a old English lathe , pre 2 world war times for 500 dollars I am eager to buy, Litton Machine Tool company Ltd. it's said to bee 4 feet, I cant find any info on the lathe or company. its missing the gear cog wheels for threading and maybe also for feeding longitudinal I can get myself a set of gear cutters and make them on my milling machine, It shouldn't be too hard should it. One of the problem is that I have no knowledge of the gears missing, But I can measure the threads on the lead screw, and the cogwheel from the drive shaft and go from there, It should be the right way to go don't you think? so I can start with the metric threads and then work my way to the other threads. I love these old pre ware machines. I have a small chines lathe (it's supposed to made for a German company) and a Taiwanese "wrong fu" and the rest of the tools needed for the job except gear cutters. Do you have any comments?

[@neptun733]

I found the Lath among your vintage machinery page, and it's a Hendey pre 1904. so owe you and your friends a great thanks for the dedication you have for preserving both machines and the information you manage to gather. Thanks!

[@Tex260Z]

Here's a question for you guys. I have restored my cross slide with Turcite, do I still need to use way oil?

[@VintageMachinery]

YES!

[@KG-yn9qi]

Looks like you've been stealing some blue berrie pie, fingers hive you away Ha Ha Oh Mr Wiggens said you didn't tell him of my concern of his being ????

[@jamesmanoni]

Bit of advice, don't put your fingers in the hole for the compound whilst sliding the cross slide, it hurts, I know!

[@Landrew0]

Did the granite slab lose true because of the weights?

[@paulcopeland9035]

You're not serious! That slab is massive (re: the videos when he brought it to his shop). No way would that amount of weight have an affect on the slab.

[@jusb1066]

dunno it had a mountain on it for about 2 billions years

[@Landrew0]

Rock is a liquid if I recall correctly. Lots of mountains have curved and folded layers of granite.

[@infoanorexic]

I've got a hunch that usage (wear) has a lot more influence on accuracy than weight. They still need to be checked and lapped in from time to time, so the cause really doesn't matter that much ... and it should go without having to be said that using a surface plate as a long term storage shelf would be poor practice ... but that amount, for no longer than it was there? I doubt that even Tom Lipton could measure a difference. Hey, Tom, are you up to finding out??? ;-)

[@darrendean21]

Landrew0 .... over billions of years .... not overnight !! Everything is a liquid if you give it enough time ... :)

[@4speed3pedals]

Turcite, salty price!

[@wallyblackburn]

What did you find?

[@4speed3pedals]

Just google Trucite. Only a handful of results will come up. I called one place, they had to call me back because they did not stock a 12"x12" sheet and was given a price of over $700. I didn't bother to ask the cost of shipping. I will do without this material.

[@wallyblackburn]

OMG!! Are you sure that wasn't for gold leaf?

[@shawnhuk]

Wally Blackburn - turcite isn’t that expensive in the grand scheme. Contact the right company tho... I just got my shipment of 8”x24” x 1/32” for $69, plus $31 shipping to Canada. www.mtsandtg.com/
