Keith, thank you for the great content. I enjoy every minute. I have noticed that your voice audio level drops off when no equipment is running. You speak up to be heard over the equipment when it is running. This causes the viewers to adjust their audio levels many times throughout a video. You can adjust the audio levels when you edit to keep the levels more consistent for the viewer or speak louder when the equipment isn't running. Thanks again for all of the great content.

[@bobengelhardt856]

Oh ... I didn't have to adjust my levels. Didn't notice any dropping off.

[@Da5idc]

Did I miss something? I didn't see any checking to make sure the angles were accurate. Also, I didn't see any measuring when setting up the fixtures

[@hairyfro]

Doesn't need to be very accurate. It just has to be a shallow enough angle to allow you to get into a 55 degree dovetail. As for the square sides, that's just for appearances. You could leave them un-machined, but machined looks nicer. If the owner wants to scrape them in square and true, they can, but there's probably not a good reason to do so.

I'm surprised there are nicks and irregularities where the 45d face meets the bottom face. I would have thought that that edge was the "straight edge" and would need to be very smooth and "straight" Also, I'm not a machinist just hooked on watching Keith do this work. I'm not sure what these straight edges are used for, obviously not scribing straight lines, that edge is way too rough for that. Thanks for any clarification.

[@Jon2jammy]

Hey, you can go to Keith's older vids where he uses straight edge tools to 1 check flatness of machine surfaces and 45d part of tool to check dovetail wear on lathe cross slides all prior to scraping said machine surfaces for flatness and alignment to each other. I think it was his big monarch lathe, maybe 10 EE lathe, hbm and the big old planer. Interesting process of getting precision back into old or worn out machines.

[@machinistrrt]

It's good to see the old machines still working. Q: do these iron sand castings move much after you crack the skin? My experience has been with light metal-Alum and mag. Mag especially moves a bit once skin is machined.

I'd like to buy one of your straight edges. You are definitely to far away for me to make a trip to your class. But having a 3' and a small one like that would be perfect for me when checking heads and blocks. I could determine if I need to send off the part for servicing or not quickly. Great video, Keith.

Nice video. Ok, I am not a in the know. What is a scraper? What does it do?

[@hobbiesrus]

It will be scraped into matching a reference granite surface plate. Once it reflects the surface plate, you can take it to your piece of equipment your need to scrape. You will ink up the surface plate, scrape the straightedge over the ink, then rub that on the part to scrape. The transferred ink shows the high and low spots to begin scaping for level.

Another great project! At around 26 minutes the camera picks up the fine dust and sparkles in the air. I have often wondered how much "dust" I have inhaled over the years, and what that does to me. I should probably have worn dust masks much more than I have... As evidenced when I blow my nose at the end of a day.

[@bobmazzi7435]

It depends on what the dust is. Cast Iron is probably the least bad for you. Any particles in the lungs will embed and then rust away. And your body uses iron, so within reason, probably not a big deal. Towards the other end would be something like Beryllium Copper. That's fairly toxic and I'd avoid anything that produces a dust rather than a chip. There are also a bunch of things that would have to be considered on a case by case basis. Plastics, especially glass fiber reinforced ones might be pretty bad.

[@calvinteeter2514]

Just curious, wouldn't running coolant keep those fine particles from becoming airborne?

[@2testtest2]

@@calvinteeter2514 It would. It would also turn your coolant into a lapping compound XD.

[@deemstyle]

Did you indicate in that 45 degree machine setup off camera, or was it really set solely from the protractor scale on the machine? Considering you're creating a reference tool, setting from only the machine scale seems beyond odd to me. Will it be checked for a perfect 45 later in the scraping process maybe?? Wouldn't the scraping go faster and easier if the angle was more accurately set? Perhaps my own ignorance of future steps makes this lack of accuracy irrelevant...?

[@marcsimonsen1578]

You don't need it to be exactly 45 degrees, it only needs to be less than 55 or 60 degrees, depending on the work you do.

How dare you criticize the greatest "Machinist" in the known universe!

[@user-fu1bh3dt2c]

Conspicuous by its absence is the dial indicator. For accurate work simply setting angles with the pointer is a bit rough and ready. Each axis should be indicated to be sure it is right. And if it was me I would want to assure that all of the faces on the product are parallel and square. I suppose an argument can be made (as was done) that this is not necessary but that seems like sloppy work to me. I hope the buyer of this thing will grind it before scraping.

[@TMxl-w5t]

"seems like sloppy work to me." I suggest that you educate yourself engineering practises, before casting judgement.. on a subject you clearly know nothing about..

[@martindietrich2011]

To be a good machinist you have to knew where precision is needed and where not. For a straight Edge it does not matter if the angle is 45 or 44 degrees. It does not matter if the faces are not perfectly square to each other. It does not affect the use case.....

Most interesting. Will the buyer do any more work on the machined surfaces before scraping? Once the scraping is done, how is the upper (non-machined) portion finished? Some rust remover and paint or is there more to it than that?

[@marcsimonsen1578]

Most times you can begin scraping from the machined surface. No grinding or other finishing is necessary. The remaining surfaces are typically painted with an epoxy paint, similar to what is used to refinish machine tools.

[@ellieprice363]

Several trips through a heat treating oven for stress relief, followed by finish machining is necessary before the scraping operation.

I would think you would want all machined surfaces at 90/45 to each other. You say it doesn't matter. Wouldn't it be a much more useful tool if it were accurate? It's meant to be used as reference is it not? Am I missing something?

[@hairyfro]

I just commented this on someone else's question: Doesn't need to be very accurate. It just has to be a shallow enough angle to allow you to get into a 55 degree dovetail. As for the square sides, that's just for appearances. You could leave them un-machined, but machined looks nicer. If the owner wants to scrape them in square and true, they can, but there's probably not a good reason to do so.

[@maddog1082]

Not really a criticism, just a thought. I was a bit surprised that you didn't make a bit more effort to mill the surfaces more precisely square to each other. I expected the dial indicators to make an appearance during your setups. I guess the way you did it was adequate for the tool's intended use but I'm thinking that a knuckle-head like me, using this tool in the future, is going to assume that those milled surfaces are precision cut to 90 and 45 degrees to each other.

[@bobmazzi7435]

Well, the bottom to the side angles will be as good as the scraping. But, I agree, I'd make more of an effort to get edges correct to each other. Likewise, edge to edge and front to back "should" be parallel.

[@macaroniandtuna]

For what this is used for, the precise angle between the two faces basically doesn't matter. This isn't a square or an angle plate, where you're using it to judge squareness/angles. A straight edge like this is effectively a small surface plate, and as such you're only ever concerned about one face at a time, for which flatness is key above all else. As long as the angled face is scraped flat and able to fit into a dovetail, and as long as the bottom edge is scraped flat, it doesn't matter if they're in different planes.

[@RossMarsden]

The angled face won't fit into a 45.0 degree dovetail if the angle of the face is not 45.0 degrees. I am always surprised that machinists make a lot of effort to team the vice, an then to make an angled cut, the simple angle scale on the machine is used to set the spindle angle. The manufacturer could at least provide a vermeer scale on the angle ring to get the angle of the spindle where it needs to be. Same goes for tilting vices.
