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.
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.
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 aRM
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! :)
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.
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
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
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.
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.
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.
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
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.
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 👍🏻
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!
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 :)
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. :)
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.
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.
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.
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.
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.
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 RUclips 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.
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
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 ;-)
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
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
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.
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.
The roller you are using is called a brayer and it is used (among other things I am sure) in printmaking pretty much exactly as you use it except it probably wouldn't be rolled twice: just once to evenly coat the brayer then it would be spread on whatever the wood block, lino block etc. That would then be pushed onto paper with a press to produce the print. Hope that helps!
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.
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?
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.
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 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
I like seeing the scraping. I have seen scraping with patterns mainly for oil retention. I guess you just kind of scrape in the pattern you want in those cases?
bcbloc02 Hmm! Some machinerebuilders gring the ways of machines and then just "flake" it with an pattern for oil retention, but some do the whole geometry by scraping. There are a lot methods and ways of doing it :) On the end for a machine way you want a flat surface with an good percentage of highspots and a place for the oil to stay :)
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...
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*
Hey, very nice your videos! I am scrapping a cheapo Chinese mill and because I don't have a Biax power scrapper I bought a reciprocating saw at Harbor Freight and made some modifications on it to decrease the stroke length and to attach a blade, it is working ok, for 19,99 is working great. It is saving me a lot of work, but still very labor intensive to scrape the whole mill, specially because those chinese mills ways are really bad.
Quite a bit of setup goes in to operating the shaper, but, it's worth it, that machine will probably outlast most of us here because of it. Interesting sound the sound the cast iron does on a shaper. The roller is used in lithography (and other similar applications), you spread ink over the original and then put the paper over. The powerscraper is a very interesting tool, i've seen something like it before, but it was used in another application so i never thought it could be used for this.
aserta Yes, a lot of spots to keep clean and lubricate, but its also a quite satisfying process :) Are you talking of the squeeking noise when I cut the bevel on the part? I think that was because of the large overhang on the toolbit, that caused it to vibrate on a high pitch - I put hearing protection on after a while... Good to know what the roller is used for if somebody asks me that question. I love that powerscraper - It should not be mistaken with one of those scraping tools Bosch or Black&Decker makes, those are just for removing glue and old carpet but useless for precision scraping. The Biax and Renz shapers are specialised tools for machine rebuilders that normaly, if you cant get a used one are just horrible expensive. But all that could of course be done with a hand scraper - I did my whole lathe that way and also a few workholding devices. Thanks for watching and commenting!
Stefan Gotteswinter Yup, that noise, but you're right, it's probably the overhang. No, it wasn't a Bosch, nothing modern, it was old and beat up, very blocky (so probably something pre 90's and the guy who was using it was shaping square grooves with it in 3 cm thick plate. I've no idea what the machine's brand was, aluminium housing and like i said, very beat up. The tool at the end was a piece of very hard steel (i believe) shaped like a square cutting drill but without the actual drill inside, just the outer shell. If i manage to go that shop again i'll try and see if there's any markings on it. As for watching and commenting, always a pleasure! Thank you for taking time to make these really awesome videos. :)
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.
cerberus Thank you :) Yes, scraping is not the fastest process..but the results speak for themself - With a pretty simple toolset (speaking of a handscraper, the powerscraper is a bit more involved...) you can achive very accurate surfaces.
great use of a rare machine, just wished you could have shown us more on how to set up cutters, stroke, etc. as there is very few video's on these machines, and the ones "up" are done by toolmakers, and the like; who by that very nature "know it all" and for some reason are not willing to tell us. this machine looks like a very nice and well kept example, thanks.
Great video, your channel is one of my favorite ones, I always await eagerly your next video :) It’s nice to see some scraping because there aren’t many videos on RUclips about it, especially scraping with a machine. Please show us more. Since lapped surfaces don’t hold the dye for spotting, do you have to scrape your surfaces always with “push scraping” or is a “draw scraped” surface also good at retaining dye. Have you tried using a spotting paste like Japanese scrapers often use?
Philipp Aznable Thank you for that compliment! Unfortunately there is something like a mythical thing around scraping, but in my mind ist just a craft that has to be practiced and understood...People like Richard King that are very generous with their informations help making it a popular technique again!Good question about the pull scraping, I dont know if that surfaces would hold the dye for spotting - I dont own a pull type scraper, but I will make one for myself to try it out. Same on the spotting paste, I only have the Dykem HighSpotBlue (I like it, but its hard to obtain here in germany, as its not sold here - Only in Austria) and the german Diamant spotting blue (That gives a very feint spotting and its hard to read).
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
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
Fascinating to see this, which I have never seen before how to make a surface flat. I look forward to the next video. Superb.
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.

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.
Love the shaper. Fascinating to watch the scraping procedure. German know-how!! Thanks for sharing.
Blown away with your skill and diligence. So many techniques. Thank you for sharing.
I appreciate the introduction to this skill. I am fascinated with the series of techniques
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 :)
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.

I must have an inner German because I love all of your videos Stefan.
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?
I am seven years late to the party but this is a great video!
Thank you!
Thank you Stefan, you did a wonderful job of explaining your thought process and technique.
I fins the silent movie motif quite hilarious, well done!
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 👍🏻
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".

So valuable stuff on this video ! Thanks, Stefan !
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... :)

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.

That was a very good video on this project..I have a 24" shaper but did not know there was a reverse clapper box.
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...
What that, heavy duty 🎤🎼🎹🎶cool job and music too
Loving this stuff Stefan. Thanks.
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*
Very nice!
Great video

Hey, very nice your videos! I am scrapping a cheapo Chinese mill and because I don't have a Biax power scrapper I bought a reciprocating saw at Harbor Freight and made some modifications on it to decrease the stroke length and to attach a blade, it is working ok, for 19,99 is working great. It is saving me a lot of work, but still very labor intensive to scrape the whole mill, specially because those chinese mills ways are really bad.
Quite a bit of setup goes in to operating the shaper, but, it's worth it, that machine will probably outlast most of us here because of it.
Interesting sound the sound the cast iron does on a shaper.
The roller is used in lithography (and other similar applications), you spread ink over the original and then put the paper over.
The powerscraper is a very interesting tool, i've seen something like it before, but it was used in another application so i never thought it could be used for this.
aserta Yes, a lot of spots to keep clean and lubricate, but its also a quite satisfying process :)
Are you talking of the squeeking noise when I cut the bevel on the part? I think that was because of the large overhang on the toolbit, that caused it to vibrate on a high pitch - I put hearing protection on after a while...
Good to know what the roller is used for if somebody asks me that question.
I love that powerscraper - It should not be mistaken with one of those scraping tools Bosch or Black&Decker makes, those are just for removing glue and old carpet but useless for precision scraping. The Biax and Renz shapers are specialised tools for machine rebuilders that normaly, if you cant get a used one are just horrible expensive.
But all that could of course be done with a hand scraper - I did my whole lathe that way and also a few workholding devices.
Thanks for watching and commenting!
Stefan Gotteswinter Yup, that noise, but you're right, it's probably the overhang.
No, it wasn't a Bosch, nothing modern, it was old and beat up, very blocky (so probably something pre 90's and the guy who was using it was shaping square grooves with it in 3 cm thick plate. I've no idea what the machine's brand was, aluminium housing and like i said, very beat up.
The tool at the end was a piece of very hard steel (i believe) shaped like a square cutting drill but without the actual drill inside, just the outer shell.
If i manage to go that shop again i'll try and see if there's any markings on it.
As for watching and commenting, always a pleasure! Thank you for taking time to make these really awesome videos. :)
Great Work, very enjoyable
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.
Very interested love your videos
Love this scraping video
Very nice work. That seemed to take a very long time to finish. Thanks for the video.
cerberus Thank you :)
Yes, scraping is not the fastest process..but the results speak for themself - With a pretty simple toolset (speaking of a handscraper, the powerscraper is a bit more involved...) you can achive very accurate surfaces.
great use of a rare machine, just wished you could have shown us more on how to set up cutters, stroke, etc. as there is very few video's on these machines, and the ones "up" are done by toolmakers, and the like; who by that very nature "know it all" and for some reason are not willing to tell us. this machine looks like a very nice and well kept example, thanks.
Your voice is therapeutic
Great video, your channel is one of my favorite ones, I always await eagerly
your next video :)
It’s nice to see some scraping because there aren’t many videos on RUclips about it, especially scraping with a machine. Please show us more.
Since lapped surfaces don’t hold the dye for spotting, do you have to scrape your surfaces always with “push scraping” or is a “draw scraped” surface also good at retaining dye.
Have you tried using a spotting paste like Japanese scrapers often use?
Philipp Aznable Thank you for that compliment! Unfortunately there is something like a mythical thing around scraping, but in my mind ist just a craft that has to be practiced and understood...People like Richard King that are very generous with their informations help making it a popular technique again!Good question about the pull scraping, I dont know if that surfaces would hold the dye for spotting - I dont own a pull type scraper, but I will make one for myself to try it out.
Same on the spotting paste, I only have the Dykem HighSpotBlue (I like it, but its hard to obtain here in germany, as its not sold here - Only in Austria) and the german Diamant spotting blue (That gives a very feint spotting and its hard to read).
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
