Making a straight edge blank Part 1/2

- čas přidán 16. 04. 2015
- A friend asked me if I could machine him a blank for a straight edge that he could then finish by scraping - He provided a piece of cast iron. Unforseen problems made the project a bit more involved and I show a little scraping with the Renz A20 powerscraper.

Stefan this type of metalworking video is rare and much appreciated. Keep up the great work.
Don’t encourage him.
WOW, Shaper action and Scraping in the same video.
For me this is metal working at it's finest.
Cheers Eric
I am seven years late to the party but this is a great video!
Thank you!
I love this stuff and I love how meticulous you are. Thanks!
"There will always be stresses"
My life Stefan... my life
Finally something I know on a machining video. Those inking rollers are for applying a thin, even layer of ink to a stamp or plate.
Robert Szasz I feel your pain man. there's so many extremely talented machining guys on youtube sometimes I feel smart just for finding the play button to the video. learn something everyday.
Hey Stefan, love the shaper, the two directions of clapper boxes and nice scrapping in my opinion. cheers, ;{)-------
Thank you Keith!
Ps: Wish you a speedy recover :)
I love videos like this. It's very helpful to see the whole process and hear what you are thinking as you do it. Thanks very much!
Pest789 Thank you! I am also learing in the process of doing that, today I tried a bit of a different aproach in scraping and got much better results, will show that in Part 2 - Thanks for commenting! :)
Fascinating to see this, which I have never seen before how to make a surface flat. I look forward to the next video. Superb.
Hello Stefan, your work and videos are fascinating to observe, You keep making them and I for one will keep watching them. Thank you very kindly for allowing me to see your craftmanship.
andrew stoddard Thank you for the support :)
I have an old straight piece of cast iron I've thought about making into a straight edge. Thank you for showing me how. I have a friend near by that has been to the King class, and is competent. I appreciate this video series.
Thanks STEFAN
This is a painstakingly patient project only producing the finest in precision as the ultimate product !!!
Even these words don't do justice to the tremendous effort that goes into SCRAPING.
And only U can do it with the ultimate care and attention to detail
We have seen pics of Scraped and Restored Machines, but not HOW it's done.
And this, for the umpteenth time, was again another of those ....."so that's how it's done" superb Videos.
Well done, young Man. Thanks for sharing. Looking forward to Part 2

Stefan, I have watched most if not all of your videos. This series for the second time, I enjoy the fact you are very particular with your work. My motto has always been if something is worth doing it is worth doing right or don't do it at all. Thanks for sharing
John Fink
You make me angry. Don’t encourage him.
Nice work Stefan, very impressive. I am working on scraping a medium (2000+ kg) milling machine from the 1940's as my first major project, and it's good to see different people's techniques up close. Thank you for taking all the time to show your work, maybe you've inspired me to do the same.
Blown away with your skill and diligence. So many techniques. Thank you for sharing.
Thank you so much for all your efforts in providing such informative video's. They are very much appreciated.
Love the shaper. Fascinating to watch the scraping procedure. German know-how!! Thanks for sharing.
Thank you Stefan, you did a wonderful job of explaining your thought process and technique.
I appreciate the introduction to this skill. I am fascinated with the series of techniques
I must have an inner German because I love all of your videos Stefan.
I have learnt scraping at a Technical college in Australia. It was done by hand, though we did many passes, we were not able to achieve the goal of putting two scraped surfaces together and twisting them 90deg and have them stick together. I had not seen the scraper machine you had, very nice piece of work and great idea!! I like your pursuit of perfection, thank you
Jonathan
Truly appreciate you sharing this and the rest of your videos. Enjoy watching Not a commercial masquerading as content.
Thank You ! Learning so much from your style; and choices of projects
Wow, learned something today! Great video, thanks for sharing.
Really enjoying your channel Stefan. I appreciate the care you show in your work, your tools and your shop. Great videos!
Peter Owens Thank you for dropping by and leaving a comment :)
Great work Stefan
The quality of your work and your polite character make for some of the greatest home machinists videos on u tube
Great work , keep it up 👍🏻
Hello Stefan , I just came across your channel today and enjoy it very much . Thank you !
Thanks for the shaper and scraping lessons. I attempt to level the surface with sandpaper as a roughing then proceed to the scraper, this seems to help me not over scrape and make hollows on the previous high spots.
A very instructive video!
Thank you for uploading.
I fins the silent movie motif quite hilarious, well done!
Still loving the videos, your presentation and skill is superb.
Excellent work, and wonderful video. Thank you.
Great vid as usual sir. I'm really seeing the benefit of a power scraper in this vid.
beautiful shaper. I have interviewed recently for a job (machinist) and the engineer on the job did not understand a shaper or planner mill. Thanks for hanging on to our beautiful past. belongs in the front room as it's a price of art.
I love it when I learn something new. Thanks
So valuable stuff on this video ! Thanks, Stefan !
Learning the basic skills of scraping is a real learning experience and except for the power scraper I'm working on those skill now with a K. o. Lee surface grinder.
Your my favorite channel now, thanks
great stuff Stefan. Can't wait to see the next part.
I just found your videos. They are great keep up the good work. Thank you for your efforts.
Hi Stefan, never seen this done before, was great to watch TFS "thanks for sharing" G :)
Very enjoyable Stefan....! Thanks.
Ha Stefan what a great video that is the first I have seen scraping it that extent looking forward to the next part or parts of this. Awesome keep it going.
Dave
Nice work and nice video as well, Stefan!
WOW!, I'm new to your channel but look forward to much more learning/enjoying. Thanks Much . . . .
I've always loved shaper work. Both hogging and finish work, with one exception. We used to make gibs for presses from Ampco Bronze (CU, AL & FE). It would be going along really nice and all of a sudden the stress would make the material go alike a banana. Not on every job but often enough to keep one his toes. The roller is called a "brayer". Used for print making involving copper plates. Hope you keep your HySpot in a container or plastic bag when not in use!
Love the process. I build tools, straight and true is the only way to do it. It takes what it takes.
thanks! I enjoy your videos, I have some machine tools that I do use for my hobby and I learn from you.
Hi Stefan, new subscriber to your chanel. Just a treat to watch your work, my father is a machinist, now retired, and it reminds me of his enthusiasm in his workshop when i was little. I like your statement about having the time at home to do things in the old time consuming way. I feel the same way when i'm in my garage, just doing things for my own satisfaction. To let your hands do stuff is just as important as letting your brain work (which i normaly do at work, so to say)... Again, thank you for the videos.
Loving this stuff Stefan. Thanks.
Thanks for showing us the basics of scraping. I have heard of it, but never seen it done in a video or in person.
Keep going, you are doing a great job, I learned alot, thanks! I have to try this.
Very interesting Stefan, didn't understand scraping before I watched this video - but I do now!
I think your doing an f'n' good job. The art of scraping, tis an art, after all.
Great Video Stefan, can't wait to see part 2.. excellent work.
Ray Gardiner Part 2 might happen in the next few days - I got it shot already, but the editing compartment (me) is a bit lazy...
Damn i would have so many questions and comments that i would go overboard.
Spectacular video man.
Dat shaper.....
Love it! Keep up the great videos.....
Some mounths ago I wanted to make a master like that to adjust the toolpost ways of my chino-german lathe. But at the end I surrender before starting. I envy you that have the right stuff and machine to do that. Good job.
Cosimo Marotta Aww, come on, a cheap chinese tombstone (surface plate..), a handscraper and some spotting blue is all thats needed to start. And patience :D
More machines and tools just make it a bit less tedious :)
Yes this is extremely interesting. This is a lost art. I’ve only seen one other video of a man scraping. He was building parts for a locomotive refurbishment in the US. Thank you for your very well made and extremely detailed videos.
I managed to make a straightedge from scratch using the three straightedge rotation/scrape method. came out pretty accurate I think for a first time. can't fit even a .001 feeler in between the three edges, so I think I did it right.
Congratulation to those 3 jaws. Beautiful job and your Précision is remarkable
Danke Sehr
That Old Bob
Good informative advice. Keep up the good work. I have found that should something be talked about or described in a video that I don't understand and you most of the time follow up with an explanation of why you're doing it a certain way and alternative methods or just some general information that helps to understand either the process that you're doing or how the machine works. Saves from doing another internet search.
Love your work space is brilliant.
Great Work, very enjoyable
Love this scraping video
The roller you're using is called a brayer, and it is used in printmaking; woodcut, etching, etc. Thanks for the many and continuing videos, your work in quite interesting.
Eli Griggs … the funny thing is that granite slab is likely flatter than anything that tool would have ever seen in its (originally) intended industry. Perhaps they should cross-market to machinists too.
Like the videos. Well explained. We had a shaping machine at college that got a chance to use a few times for course work that we had to do but now I wish I had more of a chance to use it so I understood it better. Keep up the videos.
At the time we were thinking that the grinder's, lathe's, milling machines would be what we expected to use back at our employers premises. It's a shame that CZcams wasn't around when I was doing my apprenticeship as this would have made some things easier to grasp and understand. But at the same time learn on the job the hard way by mistake and that way you definitely won't make that error again. Lol.
we like it! Thanks for the show!
What that, heavy duty 🎤🎼🎹🎶cool job and music too
Very interested love your videos
Stefan, great video and explanation of what you are trying to accomplish. Keep them coming.
Ron Hubbard Thanks for that comment - I am somethimes not sure if that what I talk makes sense, especially as english is not my native language :)
Stefan Gotteswinter Your English is fine. Just appreciate you taking your time to publish in English.
Excellent presentation Kieth. For you aparently anything less than prefect is unacceptable. Now my most watched site.
Bob
I found this video fascinating. Another shaper lesson! If you are not in a hurry it is a wonderful tool, far less noisy and violent than a mill. As for scraping, you may be self-taught but you know a whole lot more than I do, so I learned much. It is a technique I want to learn. I have also watched Mueller Nick's videos, but he is a real expert and I actually learned more from this video. Thanks for posting.
Reading other comments, I noticed Mr Mark Rainford mentioned an adaptation of the saw. This is a nice repurposing of an ol "Sawz-all" type saw. (Reciprocating saw.). Mine is currently functoning as a casting sand sifter, but I could re-repurpose it :)
Juan Rivero Thank you! Scraping a flat surface is not that complicated, one can get the hang of it in a few hours, but making it look god and giving it a good ammount of bearing surface is another story ;)
There are a few homebrewn powerscrapers out there, made of SawAlls - Important is that there is a way to change the length of the stroke, or it would only work for very rough work. :)
That was a very good video on this project..I have a 24" shaper but did not know there was a reverse clapper box.
Keep up the great work Stefan. Really interesting to follow along. I really would like one of those shapers in my shop after watching you make suck great use of yours.
Allen McFarlen Every household needs a lathe and a shaper ;)
I didnt know about the material stress factor, thanks for sharing
With regards to scraping, this is definitely one of the better videos, good work.
One of the other methods that relate to this, is the 3-plate methods of making flat surfaces. Have you ever considered making a video on that method? That would be (as far as i know) the furthest you can go back to the origin of flat surfaces.
There are a few videos on the 3-plate method, but none are as lucid as the videos you make ;-)
Very nice!
Great video
Nilton Polydoro
manythanks for another great video. apreciate you taking time to post this one!
Emma Ritson Thank you very much! Only drawback for me is that I realy cant keep up with all the videos out there, Your steam engine videos are still in my watchlist, waiting to be watched.
this is a subject that interests me a lot. would love to have these skills as part of my skillset. not sure i will live long enough though
OMG, hätte nicht gedacht das ich auf YT Videos über das Schaben finde! Habe das ein paar Jahre nach meiner Lehre in einer Firma für Präzisionswasserwagen (Wyler) gemacht. Allerdings haben wir nur von Hand geschabt und den Schaber gezogen und nicht gestossen. Die Flächen waren auch nicht sehr gross, aber war natürlich sehr genau.
I like the fact you vacuum rather than blow the cast every where
It seems to me when the chips are blown they just need to cleaned up a second time also you seem to locate these smaller pieces of equipment for your limited space rather than giant machines
Were the average guy doesnt have a warehouse thanks for sharing your time
Alot of work, must be a good mate.
Enjoyed this episode... didn't expect you to break out the power scraper so that was a treat to watch. Hopeful that I can find one someday for a reasonable price.
Jeffrey Pfeifer At least here in germany they show up from time to time on ebay for a reasonable price :)
Stefan Gotteswinter dare I ask, what is a reasonable price for a power scraper?
Any particular reason for using the shaper instead of a milling machine? Does it just provide a better (more consistent) surface finish to reduce the amount of scraping?
That is exactly why. Shaper surface finishes can be amazing, and they're so consistent. It's a really solid base for a scraping procedure.
Your voice is therapeutic
That dark green color looks pretty good.
That Shapers so beautiful it makes me want one so bad I simply don't have any room for it and I don't know what to do I'm thinking about building another garage
I thoroughly enjoyed watching this video. There is not a great lot of scraping videos about. And who can go past shaper action when presented with it?
Thank You very very much for taking the time to make this video.
Matt
Loved it
Very nice 👌 another great video. What works for you is ok. There's at least 3 correct ways to do a job. Choose one!
25 passes of scraping.. that's quite a lot. I don't know if I have the patience for that. Good work.
You're a very talented young man... Have watched and thoroughly enjoyed many of your videos. Thanks for sharing your work, it's definitely motivational!Looks like your first or second pass with scraping went a little too heavy just off center along one edge, which left a little bit of a noticeable low spot. Even with that, excellent work! Way better than I could have hope to do. Would love to take one of Richard King's training courses as you've done (some time after this video was shot IIRC).Thanks again for sharing...
Your videos are some of the best teaching resources. I am a novice garage " Machinist", and enjoy and try to use the information you pass along. Thank you again for the thorough presentations.
"famous last words" i felt that.. lol
Excellent topic, Stefan. Your video is very focused on the operation you are doing, and your explanations are clear and to the point.
As others have noted, there aren't too many videos on scraping. Yours is by far the best I have seen for us amateurs to learn from as your project is simple and straightforward.
I can see that it would take considerably more time to do that piece with a manual scraper than with your nice power scraper.
Would you perhaps show a bit about sharpening the scraper blade? I know that having a sharp scraper is essential.
Thanks for all of your videos. You do a great job.
Richard
I looked you up after seeing your appearance in This old Tony's video. There is something almost calming about your video if your others are like this I'll be a subscriber.
Subscribed after seeing the scraper.
Thank you!
Very well done and thank you. I wonder if this could be applicable to restoration of old hand tools for woodworking (think large planes). My background is mostly of the wood type but I've recently been getting interested in metallurgy and machining
Just hacked a 55 from an old sash weight.
Got one side pretty close.
Got the other side half way, and the first side goes banana...
Repeat...
Grr!!!
So ive tried slowly heating to cherry red followed by a day of cooling in the kiln, three cycles.
So far, it seems to have done the trick. Last nights pattern doesnt seem to have altered after hitting the other side.
Next time i might find something a bit... thicker. Better...
I knew it was meant to be a bit of an issue, but until you experience it...
*vague recollections of cincinnatti leaving castings for up to a decade after rough machining*
Stefan Gotteswinter DuraBar is a wonderful material. Messy, but cuts like butter, very even grained, no hard spots, I love it.
James Kilroy Yeah, love that stuff too - I always stock a few pieces. If only the mess wouldnt be there when machining it... :)
Stefan Gotteswinter No doubt, the shop vac is your friend. I envy your power scraper, I'd love to have one but they tend to go for big bucks over here ($800+). I am stuck with the old manual method. Not too bad for finish work but a real pain when you are roughing.
Cool safety boots Stefan! :D
That shaper is a beauty
F22xSTEALTHx I absolutely agree :)
