Recommendation? Cooling plates

[PEU]

I've been using aluminum cooling plates for my stainless hardness knives for years, but the heavy lifting is getting tiresome, so I drew this contraption to make the same with less effort, also I will add watercooling channels to it.

Before starting the build, I would like to ask/see your solution to this, maybe is better or simpler, no heavy lifting required is a REQUIREMENT!

Thanks!!

My plates aren't very heavy, maybe they're not big enough for you though.

Probably he use additional weight on plate

My plates are 400x100x20mm (16"x4"x0.8") aluminum, but I also put about 15kg (33 pounds) on top so all blades come out straight as an arrow, I mostly grind hardened.

I like that design but it is for one blade at time ? I saw somewhere here design for multiple blade ......

 

[PEU]

one blade at a time is fine to me, I want less effort on the heavy lifting side.

The problem for your design is the plates will be spaced a set distance apart when parallel. They will not be following the blade in taper and may not be parallel to the blade depending on the thickness of the blade and packet. Your basic design for clamping pressure is fine, but you want the upper plate to be lifted at the center with a ball type mounting so the upper plate can position itself as needed to match the blade for the closest fit. Two upright guides toward each end will keep the plates aligned

Stacy is right, you wouldn't want risking the plates not making as full contact as possible with the knives surfaces.

There are milion different shape of knife and grind How you will press between plate knife with distal taper bevel and with distal taper tang ?
If bevel on blade is not grind full to the spine and we have small flat part ?
It is impossible to make plate/tool that will work on any knife and make more then say 20 % contact blade/plate.That s way pressurized air is used .I see this tool more like tool to keep blade straight .....

I screwed my aluminum plates to a cheap wood working vise and mounted the vise 90 degrees to the way it goes on a benchtop. The handle to tighten it is on the top, I can slide the blades in and let go without them falling out, then tighten the plates together lightly. I've noticed if I overtighten the vise the plates will cant a little..

Something you may find interesting - Grimsmo uses a small arbor press, with the plates attached. This video includes a lot of extras, but I'm sure your can pick out what's relevant. I'd expect this is simpler than building your own, and you don't have the rotational aspect. Disclaimer though, just to be clear: I have not done this myself.

95% of my knives are hardened without grinding, so they are flat, since they are also mostly kitchen & bbq they thin too, again almost all my knives are 2mm thick (0.07") small fraction goes from 2mm to 4mm

I saw what Grimsmo did, but that jig works fine for folders, not sure if I can scale it to large kitchen knives.

If you only use one thickness, it is flat, and the foil packet is folded the same, then you could use your jig once it is spaced for the final packet thickness.
