DIY Hand Scraper Build
Вставка
- Опубліковано 8 лют 2025
- Having reached the point where i have enough new scraping projects on the drawing board, it's about time I upgraded from the mechanics set i've been using the last couple of years.
I substituted the countersunk screw for a button head because that's what I had to hand.
I now have scrapers and carbide inserts for sale on my eBay store here:

I am the proud owner of the "Oh no, it's on fire" limited edition hand scraper that you made. It's a fine bit of tooling and will be featuring heavily in some of my forthcoming videos. More power to your elbow! (Especially when scraping). 👍
That's great! I can't wait to see how you get on with it!
@@ImpracticalMachinist I used it in this one, it did a fine job 👍 ua-cam.com/video/z0ACMMm-ZGc/v-deo.html

I spent 6 months of my apprenticeship in the 1960’s, learning how to, and doing a large amount of scraping, the technique I was taught is quite different to yours, and the finished product was a seagull effect, like you will see on old machine tools. We scraped at a lower angle than you demonstrate, and also turned the scraper during the stroke. Good idea though with the replacement tips, you could have a few pre made so when doing a big job, to just change the bit rather than having to re grind every so often would be a big time saver.
As it happens i make and sell scrapers and the carbide inserts now. My technique isn’t perfect and i’m envious of the people like yourself who had that sort of formal training.
Nice job, nice little job to pass a bit of time in the shop! Cheers!
Nice work. We posted your video on our homemade tools forum yesterday :)
Thanks, i'll have a few more in the coming months for you.
Impressive bit of editing!! :o)
A suggestion. Hold the scraper at 15 to 20 degrees angle to the workpiece. It is almost at 40 to 45 degrees. That's why you don't get control of the stroke length
It certainly was informative
Thank you 😊
I'm glad you found the video helpful.
Thank you for this. Have been wanting to make something like this for a long time.
I'm glad you found it useful.
Just ordered one of your scrapers from ebay was going to make my own but decided I want to see a completed one first. Plus from what I'm seeing the carbide for the inserts is kinda hard to find in the correct size.
Well i'm glad you did, thank you very much for the order.
I’ve found your scrapers on the UK eBay, do you ship to the states? I would love to have one but idk if I can take the time to whip one up unfortunately.
Love the videos, just recently found your channel and you’ve gained a new subscriber! Love the parallel/squareness video, great explanation.
Cheers!
Hi, most of my scrapers and inserts go to the states. I ship through the eBay global shipping program which takes care of your taxes and duties.
Thanks for subscribing, I’m glad you like the videos.
Nice work, any idea grade shaft body is?
They’re just plain mild. I’m manufacturing some in tool steel, but it’s not necessary because there’s just no wear on the shaft itself.
A solid firm table will make your scraping process easier to control, there is too much movement in a Black & Decker work holder. You need a base that is solid and has no movement when you apply a hand scraper to the work piece. You need a heavy steel table or a heavy duty wood table with solid supports to the floor secured to the wall or floor so it does not rock back and forth.
The workmate is surprisingly stable with a bit of weight on it, though obviously not as stable as a proper bench. For the purposes of filming at the time though it was just handy.
I found out that an oscillating tool with a carbide edge blade makes an ideal scraper and works better than a biax.
I'll reserve judgement on that until I see a demo, i've certainly seen it suggested but i've not read any tales of success. I've seen reciprocating saws turned into power scrapers though.
@@ImpracticalMachinist Well, it's fairly precise, but a cone stone on a rotary tool works well too.
That I have done in the past for small pieces, a knock off dremel with a flexi shaft works pretty well. For anyone else reading this it's important to be gentle so that it doesn't dig in or scratch.
I understand that you were making and selling these now? Where might I purchase one? Or maybe I could trade it for a can or two of rust preventative? Oh the rust on your tools... the poor tools!
I still am there just hasn't been a full batch made for a while. If you're in the UK just send me a message and i'll make one up for you, otherwise you can head over to my ebay store and message me there.
Rust? The workshop is climate controlled these days, no more rust for me!
@@ImpracticalMachinist Will do.... and you should go back and rerecord all your old videos so those of us who are oxidaphobic (I made up a new word just for the occasion) don't go into spasms and start scheduling a tetanus jab when we watch your vids. 😁😆😆🤣🤣 Keep up the great videos!
Is the narrower handle as comfortable as the wide one?
It’s entirely personal preference, I find a broader handle a bit more comfy for the longer scraper but the narrower one for a shorter scraper where I’m actually holding the handle.
do you have a link for the plans you used to make this? Thanks
If you pause the video you should be able to make out the dimensions, it’s just 20mm steel, with a cutout to suit your insert thickness at one end and a clamp to suit.
Nice video but the volume is way too low. I was listening to other videos at 12-15 on my volume and at 66 I could just hear your voice. Also, it would help if you described the dimensions of your material better. You didn't mention the thickness of the metal bar and even on your drawing, which you kept covering up, it does not tell the width of the material. Looks to be about 25mm (1"), but that's a guess, it could be 30-32mm (1-1/4). Also, a good technique is to put a radius at the back of the blade base. This keeps the blade held by two points and prevents it from trying to pivot in the clamp if you put a radius on the backside of the carbide, as well as in the front. If you have a limited number of scrapers, you can get a 25x25 blade and put a different radius on 2 or more sides. Except for the volume, good video. Thanks for the inspiration.
The width matches the insert width, so in this case 20mm, but you can go as wide as you reasonably like, likewise with the thickness of material, I use 5mm but for a shorter scraper you may want to shave it down for more flex. I understand that some people do machine a crescent into the back of the clamp to prevent the insert from wandering off to the side, in use this hasn’t been a problem and the clamp holds the inserts nice and tight. For larger sizes of insert however it might be more important depending on how much you’re leaning on your scraper.
The volume is a strange issue, hopefully one that’ll be solved the next to me I publish a video.
Thanks for your comment.
@@ImpracticalMachinist Thanks for the informative reply. My carbide arrived today and I'm making several scrapers similar to your design but with 20mm brazed tips. Thanks again.
Do u have any in stock
There is a 650mm scraper with a hand turned maple handle which is supplied with a carbide insert, in stock on my Ebay store.
is that steel they say steel is hard to scrape
Steel isn’t all that difficult, I find that I get a scratchier finish compared to cast iron but it can certainly be done.
