Thin slitting saw blades work well. I have a drawer full of scrapers made from them. Its an old pattern makers trick. Once they go dull cut it in half and grind the teeth off. Something like one of these.

You can grind down old files. They are quite
hard and trash otherwise.

O1 steel is also widely available. It comes
soft for grinding to shape It can be
hardened and tempered using a propane
torch and a coffee can of motor oil.

Don’t know if you have the skills or equipment to do what you want to do. But it can be done!

Read what he says about old files! Also tools, equipment & skills needed in these two articles.

Russ echo first article about old files, but goes on to say can make good scrapers from truck springs with out special equipment and supplies. Have seen several homemade car spring scrapers and they do just as good as HSS.

All about the burr on a scraper!

If don’t know what you are doing can actually take the temper or ruin HSS! Yes occasional bluing might not hurt much but too much not good for the steel.

Try ebay and search for O1 tool steel.

1/4” is too thin for a 1-1/4” scraper. 3/8” would be ideal. However you can get a 1” X 5/16” BB scraper from PSI that already has a handle for about $20 plus shipping. Time you buy HSS I can’t see how it would be cheaper to make. My 1-1/4 scrapers are 3/8” thick from Thompson tools. Pricey, but well worth it. For tools you are going to use a lot get a good quality tool. If only occasional use ge BB or Hurricane.

I agree with others that 3/8 will be a lot better than 1/4 thickness in reducing vibration.
I’m pretty sure this is the PSI that I have heard lots of good + about.

For steel I usually go to Speedy Metals. Lots of sizes and sold by the inch or foot. This is tool steel not M2. They told me A2 or D2 would be best but I would call them. If you have a torch (not a little map) you can do an OK job hardening the steel yourself.

M2 gets very expensive and in bits the problem is the length. WTTools has some up to 8” length in M2 and M2+5% cobalt. Eight inch length is fine with me because I will Never be 6” over the rest. For smaller items like boxes I like the 1/2” square. They do not seem to show the standard M2 right now (normally $9) but do have the M2+cobalt for $15 which is what I would buy anyway.
Depending on your handle you may profile each end giving it double duty. The 1/2” thickness gives it a lot of support (think of you parting tool which is not nearly as wide).

I know of no place that carries HSS in thick (3/8) and wide stock probably because it may not be used for metal working operations.
Just some possibilities…..

thanks for all the information Lee, I can see that making my own scraper would not serve any purpose. I t would be different if I already had the tools. I think I will stick with PSI. I like that scraper you showed, I have some questions, I want a scraper that I can use on the side of bowls or boxes if I try that, can that scraper be sharpened on the side. I know many turners regrind tools for a specific purpose but I don’t know what I can and can’t do. Thanks Mike

Search for metric sizes:

Whether these make economic sense is up to you.

I’ve made some smaller tools using similar parts, and for those, it made sense. The shipping is free, but slow, fwiw.

Mike, just because a scraper has a sharpened side doesn’t mean that you can have that whole side in contact with the side of the bowl. My experience is if I have more that 1/4” of cutting/scraping edge making contact, I’ll get chatter, and the more surface you have contact with, the more chatter you get. Keep that in mind when using your tools. I believe I mentioned that in my youtube video of the “Three Bead Tool” I made. The commercial round nose scraping tools I’ve seen and used are either right or left handed tools. They are sharpened from the nose around the side almost to the handle. Nice tools, but too much contact will create more chatter than you like. I made my own out of a leaf spring. It works for me….... Jerry (in Tucson)
