0.7mm slot in wood?

Community

Maybe a silly question, I was thinking about making my own bench scraper for cooking and such.
Looking at my existing scraper, the wooden handle has a slot that is about 0.7mm wide and 22mm deep spanning maybe 5 inches.

How the heck do they manage that? Is it something I can do in my own little shop?
I looked for thin kerf table saw blades and couldn’t find anything close.
Maybe there’s a band saw blade that could do it but I just don’t know, it’s so straight for such a long span.

Let me know what you folks think, I expect someone here has the secret…or it’s not a secret and I’m one of the lucky 10,000 to learn some common sense today :beers:

Thanks either way :slightly_smiling_face:

Bonus points if you can point me to a source of decent stainless steel that doesn’t come in 4’x8’ sheets :sweat_smile:

I suppose worst case, I could source the steel and put some teeth on it to cut its own slot.
Or maybe with some decent work holding and blade guidance, a fine hand saw could do the trick :thinking:

My guess would be a bandsaw bade cut that, There might be a 3,5” mini saw blade with that kerf size.

If you set up two overlapping passes you could use a JointMaker Pro:

Yikes, that bridge city tax is rough. Though I’ll admit it’s just as pretty as everything else they make.

Maybe I’ll buy the blades and give a go at using them in my own jig before giving up and buying the joint maker in the end. I’ve got some other uses I could think up to justify the cost :thinking:

Good call, I’ll look around. I hadn’t thought about checking whatever scale model makers use but it feels like they would have to do similar cuts.

Yep, @Redlander hit the nail on the head. ~3” diameter hollow ground blade and a 0.025” kerf should do the trick.

Now I just need a tiny table saw to put it in. New tool time :grin:

Use two pieces for the handle, not only does it avoid the problem you are working on but it also provides you a way to mechanically hold the blade in addition to the two halves of the handle together. Also allows for blade and/or handle replacement.

From your picture I can make out circles/pegs.

It is steep, but the fine joinery that could be attained is incredible. The ability to dial in a fit by hand is unique for sure.

There is probably a “dremmel” tool style table you could make?

Yeah I thought about that but I like the look and feel of a single piece handle enough to try making one myself.
I’ll probably end up making a few of each type to be honest. Looking to knife making for inspiration on the multi-piece handles.

You spotted brass rods holding the blade on this particular scraper :ok_hand:
