I'm at a similar situation with my Bridgeport, needed to mill the tools to fix the mill etc. Great video, and an inspiration to keep going. I too bought a casting from Martin Model and am very happy with it.
Gary Martin is outstanding as are his products. I have bought several things from him and he always a great guy to deal with. I had a friend of mine Plane one of the same straight edges for me. He was impressed by the quality of the casting. It sure scraped in nice. Looking forward to seeing theh mill restoration. Something I enjoy doing when I can. Cheers
Plenty to learn when scraping and the more you do the more you learn. Do check your working face against your SP before taking the SE as good on your mill. The CI will move especially after machining but also as the shop temperature changes. Good luck with your mill refurbish 👍
Did you inherit a bunch of money? Rob a bank? The Biax scrapers are a dream for rich people. You did a good job scraping. Your technique allows for individual, consistent points of contact. Hinging is critical. I didn’t see you try to rock it to check for bowing but it looks really good man.
Thanks! It’s actually a Hungarian made power scraper- I did a video a while back on it here: th-cam.com/video/0c7smmID174/w-d-xo.html With shipping from Hungary, it was less than half of what a used Biax costs.
Enjoyed the vid. Without even owning a SE, I went down a rabbit hole. No idea how far you want to take your SE scraping, but on PM I found an interesting discussion about it titled "Camelback Straight Edge - It Moved On Me". New to me at least was "Ringing" a SE with a rubber mallet during scraping for stress relief of the SE and maybe some added mental stress relief as well. LOL
It’s not an issue in one this size, but weight becomes a factor with granite in larger sizes, whereas cast iron can be webbed to save some weight. The granite ones don’t usually have the dovetail either. The cast iron ones can also be checked and tuned up on the surface plate as needed. And cost to some extent.
The advantages of iron straight edges are the same as that of iron surface plates. Moore says in Foundations of Mechanical Accuracy that iron surface plates can be corrected by scraping or lapping, but granite plates can only be corrected by lapping.
Very nice! I'm a bit envious of your power scraper. May I ask what brand it is and where you got it? I was very interested in purchasing one until I saw the prices. 😞
It’s an Evig Power Scraper, made in Hungary in the 1970’s(?). I got it on eBay, and have found no info on it or ever seen another one. I did a video on it here: th-cam.com/video/0c7smmID174/w-d-xo.html
if that granite plate is from China, then it has 1 micron (or 2 microns) error in the flatness. Not very high quality I would say. Better flatness is achieved with 3 plate method (about 200 nanometer error)
Almost as impressive as your scraping, is your slow motion in fast speed. That has done my head in. Waiting for the rebuild as I may pick up some tips.

I like the part where it's blue
So very blue.
That looks beautiful. This thing belongs in a museum. But I think it will be more useful in the workshop :)
Nice job. I wish I had the time and patience and time to get into scraping.
I have no clue what you did. I like the idea of using a box for painting small parts. Thanks for the fun.

Scraping is an art in its self. I've done it some but I know some people who are professionals one has been doing it foe 40 some odd years.
You did a nice job on that.

And another video in such short time?
How cool, love it !
Nice work.
Great job.
Thanks for sharing.
Take care, Ed.
The patience of a glacier.
You make it look easy. I like the blue too as others have said.
Top work Jeremy!
I totally wanna see that making a square bit!
Very nice work sir.
WOW Jeremy, you know how to do a LOT of stuff. I wish I had half your brain…..I’d be doing pretty well in life. Thank you for another cool video 👍
I think it’s more a willingness to try and a curious mind.
Plenty to learn when scraping and the more you do the more you learn. Do check your working face against your SP before taking the SE as good on your mill. The CI will move especially after machining but also as the shop temperature changes. Good luck with your mill refurbish 👍
I feel like scraping is a process you can learn in an afternoon, and then spend a lifetime trying to master.
Did you inherit a bunch of money? Rob a bank?

I didn’t show it because it seems crazy, but I did go after it with a ball peen hammer before I started scraping.
@@JeremyMakesThings the price point of "Free" is affordable at least.
nice job !
Good project. Is there any advantage of using cast iron over granite straight edges ? They're a few hundred bucks new or even cheaper on eBay.

The granite ones don’t usually have the dovetail either. The cast iron ones can also be checked and tuned up on the surface plate as needed. And cost to some extent.
@@JeremyMakesThings thanks, the weight related point makes a lot of sense

Oy hey, so many vijeos in such a short time frame... Is it Christmas?
Chào bạn, cho hỏi cái đó để làm gì vậy bạn
I'm still trying to get the blue off my hands, refer to me as papa smurf.
Good job pal, its flat. But it GLIDES?!?!
Dont ever air grievences again. Its not my fault you dont like xmas
Thank you for the opportunity to add to my list of "This channel is supposed to be Jeremy MAKES things not...." complaints.
Jeremy FINISHES things?
😀
It’s only a questionable set up if it doesn’t work. I can’t count the times I got away with one. 😉
It’s questionable until you get away with it.

i have some knowledge how that tools are factory made and dude, wtf, u destroy it !
