I did the same thing. I had an old reciprocating saw and didnt want to spend the money on a Biax. I cut the stroke down to about 3/16", Made an attachment and some carbide blades from old files and inserts. It worked like a champ! I rescraped in my first CNC with it. Took four months but well worth it. Have used it for making allot of tools because I dont have a surface grinder. Thankyou for making these videos. People like us are rare these days...
I love the advice that if you want to do something then just do it. This is sincerely something that hinders me a lot in getting things done; overthinking everything and only seeing issues down the road.
@Niels : You just described me! My father's advice was similar; just take the first step... the rest will follow. If you never take the first step, you will never achieve anything! Sadly, I was never good at taking his advice.
As always your skills and the dedication are amazing. There's a lot of practicing, preparation and learning behind these kind of works. That machine will end up more precise than new for sure!
When I saw the thumbnail I thought "huh never seen a Hitachi scraper before, must have been sold in Japan only" was quite impressed to see it was a modified reciprocating saw. Good job making it look almost factory.
Good job. Just do it is great advice. In the USA too many people are too busy whining and crying about why they can't do something. We need more people like you in the world. Very motivating video. I'm going to consider making a power scraper based on your new one.
I'm currently trying to fix up an old English milling machine and take the wear out of it, this video is perfectly timed for me! I really like your work and the quality of your videos, it's inspiring!
Excellent engineering skills! You are one of the best metalworking professionals I have ever met. Each of your videos is like a breath of fresh air! I wish you good health and please spoil us with your new videos, with the deepest respect for you with greetings from Poland!
Making your own version of a Biax scraper out of a sawzall is something I have always wondered if it was possible since the first time I saw a Biax scraper. Nice work. thank you for the videos.
Mr. Lem, you've done it again. An absolutely amazing concept and inspirational video. You are so talented, I'm looking forward to the CNC build. I'm sure it will be awesome. Thank you for sharing.
You sir are an absolute DIY beast! I wish I had your skill and ability with metal working. Can't wait to see your next video in the series and what projects you have in store for the future.
Always awesome to watch a "master" learning new skills! There is something truly beautiful about a hand scraped piece of tooling! Thanks for sharing 🇨🇦
i just ordered the closest model saw i could find on ebay right now after seeing this. cr13v2. i’ll have to relocate the speed controller in trigger as mine does not have the remote speed knob like your model. the models available here with speed dials have some blade tilting device I didn’t want to mess with. you rock bro. this looks way more legit than your early model. I can’t wait
i bought one too! showed up yesterday! best I could determine is the speed dial wasn’t offered on the 120V models. [ without tilting blade thing anyways) . Mine i’m guessing like yours is also without a bush in the case for output shaft and uses 2 o rings and a cloth dust wiper. factory packed it with an amount of grease you don’t see today. the output shaft bearing is also without oil\grease grooves so i’m considering adding a proper bush to mine like shown here. I’m trying to find better photos or details on how this shaft coupling stroke adjusting device was designed. offer any direction wobbler design to help me make mine? this video is the only info on a wobbler type converted tool I know of. I bought my donor tool on ebay in the middle of night following discovering this video. having watched his 1st build video a wile back I had no doubts this is the best thing to build if wanting to avoid paying way too much for production made power scraper.
Beautiful work Ca Lem, thank you for sharing. It is a good strategy to explain the electrical scraper in a video about scraping, since it helps keep the video interesting for a wider audience. Just scraping alone is kinda boring, even if it's like meditation to actually do it. I am very excited to see the next installment. Your craftsmanship and quality of work put the original manufacturers to shame.
More please. can't get enuff of your videos. Woo Hoo, I've got one of those Hitachi saws,... Now all I have to do is convert it... mmmmm I think I'll be watching this vid a whole lot more, and that's a good thing in itself!
I want to learn to do this. Scrapping metal till its perfectly flat Ha subbed because of the advice. I use to think i could do things perfectly! I just have to think harder! But all i ever did was think!!
Linear guides and no problems. I have do scraping on my lathe, i was so heavy and takes a lot time, dont want to do this work again. Only rails. Big size and roller type and happy will happen. Precision...if hands grow from correct places, even on very bad mill/lathe machine you can reach 0.01 tolerance of details anyway
I'm trying to find the video on Robrenz, can't find it. 6:41 - Thats great has no vibration. There is a new saw machine which is called "Flex" brand that have 40% no vibration designed that way. I wonder how it compares to the Hitachi. Thanks.
Great! How much time did you spend already on doing that? I was about to do the same to my machine, but I gave up due to not having enough time to do it. Hopefully I won't regret that as much. Keeping fingers crossed for your work :)
Hi , are there any sketches of the parts that you have made or modified? I build the Mk1 , and like you agree that that design has a lot of vibrations .so I thinking on building another with this new design, thank you for sharing
you rock. much respect for you and your skills. do you know where I could see or learn more about this adjustment device idea you used? I have bought a cr13v2 as closest model saw I could find after watching this the other night. my saw arrived yesterday :)
@@lexdavis2179 I believe I understand what he did now also. going to plan and maybe start some parts this weekend. thinking 4140 and try some different tempers but this will be new to me having not run 4140 in my oven before. what are u planning for material ?
I don’t think I’ve ever clicked on a notification so fast, I love this channel
His ingenuity is always impressive.
Mine too!!
Cutting Edge Engineering and Ca Lem posting vids on the same day is 🔥

Perfect isnt real! Its just you doing things!
I've watched all of Ca Lem's videos & I'm starting to think that if he fries an egg, it cones out perfectly round!!!
And flat and concentric and parallel....
I never had any interest in scraping until watching your videos. Always awesome stuff - thanks for the inspiration!
Thanks man 😊
Always gives me a big smile when I see a new video from Ca Lem!
Really clever the design of the adjustable mechanism in the scraper. I definitely keep this in mind! ;) Thanks for sharing!
As always your skills and the dedication are amazing. There's a lot of practicing, preparation and learning behind these kind of works. That machine will end up more precise than new for sure!
Love and peace! From Fan of Sweden 🇸🇪. Thu ms up.
Nice to see you at work in the shop again. All the best.
When I saw the thumbnail I thought "huh never seen a Hitachi scraper before, must have been sold in Japan only" was quite impressed to see it was a modified reciprocating saw. Good job making it look almost factory.
Absolutely brilliant workmanship and all self taught is a huge achievement. Well done on some top notch fitments
Great idea to support the scraper on some sort of bungee cord.
More than your great skills, I admire your determination!
I just found this channel this morning and have been binging this content. The restoration vids are amazing. Thank you from canada
Hi, I am a new subscriber from Canada. I am very impressed with your work. Thanks so much for sharing your work. Bob
You are amazing Ca Lem ... simply amazing!
New subscriber but I have been watching your videos for about two years now. I truly appreciate and enjoy your videos. Keep it up.
Wonderful work ~ Love to see you in your shop and creating !
very good job Ca Lem..thanks for your time
You amaze us once again, can't wait to see what you show us in part 3.
Good job. Just do it is great advice. In the USA too many people are too busy whining and crying about why they can't do something. We need more people like you in the world. Very motivating video. I'm going to consider making a power scraper based on your new one.
The best, enjoy watching you make the tools you need.
I'm currently trying to fix up an old English milling machine and take the wear out of it, this video is perfectly timed for me! I really like your work and the quality of your videos, it's inspiring!
Everything was done to your extremely high standard young master 👍
Excellent engineering skills! You are one of the best metalworking professionals I have ever met. Each of your videos is like a breath of fresh air! I wish you good health and please spoil us with your new videos, with the deepest respect for you with greetings from Poland!
very inspiring creation. I especially appreciate implementing counter balance to eliminate arm fatigue. 👍👍😎👍👍
You have an amazing ability to work with what you have and conquer whatever you put your mind to. Love this channel!
Working out well, nice adaptation.
Thanks uncle Randy
Making your own version of a Biax scraper out of a sawzall is something I have always wondered if it was possible since the first time I saw a Biax scraper. Nice work.
thank you for the videos.
You are a genius to be honest
I am so glad you are back. Your work is fantastic and inspirational.
Great respect for you Ca Lem.👍🍺🍺
Awesome! I've been looking forward to Part 2. Fantastic scraping.
Beautiful work as usual. Thanks for sharing you work.
Mr. Lem, you've done it again. An absolutely amazing concept and inspirational video. You are so talented, I'm looking forward to the CNC build. I'm sure it will be awesome. Thank you for sharing.
Improving a tool to improve another tool. My kind of craftsman! thanks for sharing your passion.
Amazing workmanship!
You sir are an absolute DIY beast! I wish I had your skill and ability with metal working. Can't wait to see your next video in the series and what projects you have in store for the future.
Some great work there, really impressed with your attention to detail.
LOL that bunji cord, great idea. If you want to be more mobile with that scraper maybe a guitar shoulder strap would help. Love your vids bro.
Ha! Old school! Cool! We do the same work here, in Russia. Scrapping and geometry correction. You Rock, Ca Lem! Will wait till finish!
nichts ist höher im maschinenbau als die hohe kunst des schabens.ich bin sehr beindruck, vielen dank das sie sich die mühe gemacht haben.
We all miss you buddy!!!
Glad to see you back!!!!!
:)
Superb content as always. I admire your ingenuity and can do attitude.
*best. video. EVER.* as always, much thanks and deepest respect.
Always awesome to watch a "master" learning new skills!
There is something truly beautiful about a hand scraped piece of tooling!
Thanks for sharing 🇨🇦
Incredible work! Incredible preparation! I only wish I could watch 100 more videos from you on this idea. :) :) :)

I can't wait to see the finished product! You always do a bang up job, mate!
Good Job !! I Love your way of thinking!!!,👍👍👍
Very excited to see where you're going with the cnc and what you'll be making with it!
Nice. Ready for hour and hours of scraping :)
Excellent video, Cà Lem! Keep up the great work!
Watching you is an inspiration!
That was really great!... Thank you. 👍
I (and other viewers, I am sure), would be interested to see the sharpening process for your scraper tools. 😊
Great video 👍 I think your videos will inspire many more to get into engineering, and as the saying goes"if it looks and feels right it usually is".
Always enjoy your videos. Need a tool, make a tool. 👍👍
Amazing work as always
nicely made scraper. As always you are extremely impressive.
More please. can't get enuff of your videos. Woo Hoo, I've got one of those Hitachi saws,... Now all I have to do is convert it... mmmmm I think I'll be watching this vid a whole lot more, and that's a good thing in itself!
Two footed twist gage! Outstanding 👌
You sir are the definition of the word: Machinist
I would love to hear of your origin story. How early you began. Your mentors.
Great skills, I admire your determination!!!!!!!
Been waiting impatiently for your video as always. Thankyou
I want to learn to do this. Scrapping metal till its perfectly flat
Ha subbed because of the advice. I use to think i could do things perfectly! I just have to think harder! But all i ever did was think!!
You and Robin should've done a collaborative video on this build, it would've been awesome as your both great machinists! 👍👍
Linear guides and no problems. I have do scraping on my lathe, i was so heavy and takes a lot time, dont want to do this work again. Only rails. Big size and roller type and happy will happen.
Precision...if hands grow from correct places, even on very bad mill/lathe machine you can reach 0.01 tolerance of details anyway

Love your work and wit Mr Ca Lem. Happy new year.
Gee, mister, that's a lots of exercise! 😵💫
Master Cà Lem, as excellent as we got used to by You 👍
As always you are one of the best young machinest on RUclips,but I think the bearing must be double angular contact bearing.
As usual Ca Lem so impressive 👍😁❤️
I could watch this for an hour
Great video/discussion/demonstration, tks for sharing
Great stuff man!
언제나 감동적인 영상입니다..
12:48의 삼각형은 무엇입니까?
I'd like to give this at least three thumbs up, unfortunately there's only one! ;-)
How many total hours of scraping do you think you did in this video?
Does it chip the carbide if you catch the corner of the casting? I think I would go through a pile of carbide blades before I got the hang of it.
Brilliant Mr Icecream!
Keep up the nice work.
it is wery perfwctly work! good day!
First like and comment 😃 I love your project please the lube system on the ball screw for the cnc and the cooling system too really important
Awesome stuff keep it coming
Chúc anh cùng với gia đình một năm mới thật nhiều sức khỏe và thành công trong cuộc sống .
Cảm ơn bạn nhé. Chúc mừng năm mới
Very nice job, what did you do to the speed control trigger?
Great! How much time did you spend already on doing that? I was about to do the same to my machine, but I gave up due to not having enough time to do it. Hopefully I won't regret that as much. Keeping fingers crossed for your work :)
Awesome video as usual 😎
Hi , are there any sketches of the parts that you have made or modified? I build the Mk1 , and like you agree that that design has a lot of vibrations .so I thinking on building another with this new design, thank you for sharing
Well done! thank you.
you rock. much respect for you and your skills. do you know where I could see or learn more about this adjustment device idea you used? I have bought a cr13v2 as closest model saw I could find after watching this the other night. my saw arrived yesterday :)
just observed the rob renz thing after watching this for the 40th time. thank you :). i should be able to find any details now. 🤗
I am working on a CR13CV at the moment in Australia. it is a bit difficult to work out exactly what Ca Lem did but I think I have it worked out now.
@@lexdavis2179 I believe I understand what he did now also. going to plan and maybe start some parts this weekend. thinking 4140 and try some different tempers but this will be new to me having not run 4140 in my oven before. what are u planning for material ?
I will use 4140 round bar for the 2 shafts and Arne flat bar for the slide bits.@@bradgeary3467
i see you still stick to "measure a bunch of time - cut once, carefully!"
and, as usual, thanks for letting us watch.
08:20 ¿What is these yellow-liquid he´s putting on the part? And what is it´s function ? Anyone..?
Excellent content🙏
