HATAGANE Style Wood Clamps

I’m sure most of you know about these, but for those that don’t, I’d like to show you my latest shop project. I find these brass clamps are very handy when you make small projects like I do. The problem is I wanted more, but they are a little pricey and more important they can take up to a month to get here. I never searched to see if these have been made by any one here before, so this might be old news.
I decided to make one and see if it might work. The results are fantastic. These are lighter than the brass ones I own and they have enough clamping pressure for many of the glue ups I do. They will clamp hard enough to hurt your finger. Also they don’t slide like the brass ones can even when locked down.


I ended up using oak for some and even the keys from the piano I’ve been recycling for some of the components. The keys are light and soft wood, but I used CA glue to harden the areas I needed to thread.


These operate just like the brass ones do. I used hot glue to adhere a bolt to the plastic cap. After drilling the hole for the top of the clamp I used my drill with a 1/4x20 all thread and wax to cut/add the threads.


The top piece of the clamp is glued and wedged in place. The next section just slides up and down with no adjustment.



The bottom section has a clamping mechanism that can be placed anywhere on the bar. I used a screw and ground away most of the head. This was threaded through the wood, the head was recessed and glued in with CA glue.

I’ll let you know if they work out long term, so far I like ‘em.

Good replacement, alternative for the brass ones.

Neat! I should make some. My fumbly fingers don't seem so good at holding little things, anymore.

Innovative! I’ve always liked the look of the brass ones…

Ryan/// ~sigh~ I blew up another bowl. Moke told me "I made the inside bigger than the outside".

ive checked out the brass ones and yeah, not cheap. may have to make a few as i get older the projects seem to be getting smaller.

working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.


Good adaptations and write awsum... one thing wrong unless I missed it... where's your

logo???

For someone that buys too much crap... I don't necessarily mean useless stuff, but often more than I need and often not too shekel conscious... I've never invested in them though I do a lot of small stuff.

Every time I let the spend fairies take over, they are always at full price and whenever they are on sale (or more reasonably priced) I miss it.  Seems like the cycle has repeated so often that I've built up an arsenal of "acceptable" alternative smalls.

Enjoy yours.

Well, I had to look up Hatagane.
Yours look just fine and I like that they can be made without lots of expensive.
Nice job, I find those little brass ones really useful as well.

Did you add a shim under the locking screw to stop it dinging up the beam?
Nice clamps, John!!

Thanks guys, I hope this helps some of you that haven't heard of these type clamps. The lack of weight makes clamp up easier because I don't have to balance the weight of the clamps to keep the project from tipping over.
Thanks Mike I did think of that, but they were so easy to make if they need one it should be easy enough to make new ones.

That's why I always use my Bessey Revo Vario clamps for tiny parts,

don't have to worry about it tipping over.

Very clever design.  
Looks pretty precise and sofisiticated.
