Peter Frise, Excellent comment .saved me typing it .especially the absence of annoying music. Thanks .

@@karlhrdylicka Same here. 100% agree.

halfway agree, it is a great example of how to and what to expect and his explanations are great also, just to me after watching so many examples it is like watching paint dry. people who are watching this activity for the first time should learn something and that is the reason for the video, education. glad he takes his time to show what he knows and stuff he will learn as time goes on.

@@gojoe36 Sounds pretty normal to me

You only scrape the surfaces you want to be level... (to paraphrase "you only need to floss between the teeth you want to keep")... He's really good at it and this core competency is mandatory for the precision machinist.

Couldn't have said it better myself! Thanks for saying it for us. Kieth, thanks for the hard work putting these videos together for us to enjoy and learn from!

To clarify, you would mix this concoction in an old Altoids can or a tin that you got a wallet in some years ago and daub out of the can. Don't try mixing this up right on the surface plate :-) You also want to have two different daubers for the different colors. "Once you figure it out, then you'll know" -Peter Kuhn

It's an interesting old machine. I'd never seen one before watching an earlier episode of this series.

I came to the conclusion that I could NOT be a precision machinist. I am too impatient!

Respectfully disagree. I am tooling-up to scrape, thanks to this channel and all of its scraping content. Lance Baltzley is another good scraper , as is Robrenz.

@@larsrodbok1285 no disrespect intended, the people you mention are all true craftsmen in there areas of expertise. i have enjoyed keith's videos for a long time and i will continue to watch and press the like button as i did here i'm sure keith wants to know where his viewers interests lie.

LOL Nice parallels "Quantum Singularity "

All will be right with the world.

"gib side"? That is the adjustment. It doesn't require scraping.

For scrapping videos you need to go to a junkyard channel.

It is not as accurate as scraping. Sure surprised me to find this out.

and squirel feeding.......

They will, but all machine tool slides will have some type of adjustable gib in them. As the slide wears normally that gib is then adjusted to keep the clearances correct. Likely he's at most taking a few thou off in total with the scraping, that amount will never be noticed with that adjustable gib.

You measure across a pair of pins seated in the dovetails at each end.

@@nerd1000ify Ahh the guage pins come in for another use. Neat Ty. Next question they are parallel but how do you make sure the angle is at or needs returning to say 60°

@@alstonofalltrades3142 It actually doesn't really matter what the dovetail angle is (within reason) so long as it matches the mating part, so generally you would just scrape one side (ideally the longer of the two) in and then use that as a master for its mating part. If you really needed an exact dovetail angle for some reason you could set a sine plate to that angle on top of your surface plate, bolt your part to to it and sweep a test indicator over the surface of the dovetail to check which way you needed to go.

Short answer:yes, but not without some skills. Check out Robin Renzetti's instagram and youtube.

No, if you have to ask then it's not a job you should be even considering.

@chris0tube Simone asked the question because he wanted to know, I gave him an honest answer. And it was worded precisely in that way because I do have just enough knowledge to say what I did. Without those reference surfaces Simon asked about and specifically that surface plate, it's logically a failure just waiting to happen.I never ever give knowingly incorrect information. He also didn't mention having a very accurate machinist level.Those aren't optional reference tools if you want any hope of being successful.And the less you know the more important they are. Yes you can literally start with almost nothing using the 3 plate generation method to produce your own proven reference surfaces and boot strap your way up from there exactly like Whitworth invented in the 1830's to get beyond the technological machine tool level they were then at. I highly doubt 1% of the people making comments here would have the drive, ambition, skills and knowledge to even attempt it. But without either buying or making those basic references as a bare minimum and knowing a lot more than what any video might provide it simply ISN'T going to happen.You can't even verify your straight edges are in fact straight. And without understanding the basics of machine tool geometry you are undoubtedly going to make things even worse. To suggest otherwise like my statement is somehow flawed and incorrect is completely misleading to others. Exactly where did I say I or others couldn't or didn't know enough to do it? No where did I say it can't be done, those points weren't pertinent to his question. Simon asked if the (apparently obvious) wear on a 1950's mill can be removed using dti's, feeler gauges, and straight edges. Simply by asking if it can be done in that way then it's more than obvious he's lacking the basic's of how it could be done. So exactly as I said "if you have to ask it's not a job you should be even considering". Anyone having enough experience to actually do the job wouldn't need to even ask the question he did. I didn't say it was impossible, I kept my answer short and to exactly what he asked about. With known verified straight edges, a huge step up and maybe having something even more helpful like a Kingway alignment tool, machinist level, surface plate and a whole lot of experience then yes it's not impossible at all, it's done every day. But asking if it can be done that way already proves that required experience level is in fact lacking. A simple once through the Connelly book Machine Tool Reconditioning more than proves my response to Simon was and is correct despite what you might happen to think. Making knee jerk assumptions about what anyone happens to know or not know and using a simple one line response to form that judgement is also a large mistake. Go ask Simon's exact same question over on the Practical Machinist Machine Reconditioning forum and there's no doubt you'd get just about the same response as what I gave him as an answer.
