Hey /diy/,
How would i go about making my own diamond sharpening plate? They're expensive as all balls for a set and I have access to diamond grit.

Would it be a matter of surface grinding a steel plate and loading it with diamond using some sort of adhesive? By far the biggest issue I think, would be making sure the stone is really flat after the grit is glued on, like a thousandth or 2 of an inch.

Any ideas?

PROTIP: Tools meant to make other tools should probably just be purchased. Becuase those tools have to be very exact, and were made with tools more complicated than you will ever understand.

Also, just get a normal fucking whetstone from your local korean grocer. I have one and all my knives are shaper than disposable razors now.

>Just buy stuff
Shoo, DMT shill!
This is a DIY board m8, plus I already stated I have access to diamond grit, I also have someone who can surface grind a steel plate dead flat for me, so sticking the diamond to the plate while keeping it flat seems to be the main issue thus far.

No you retard, just get a cheap ceramic norton wetstone. Diamond just embeds itself.

No, the entire point of /diy/ is to save money and be practical. Buying tools is often cheaper and better (like 90% of the time). I think at the most you can make bandsaws and jointers, dont make anything that is a precision tool, i.e. a stone.

Youre not a pussy for buying stuff, if it makes more sense then building it.

What is it with normies and diamond stones?

A whetsone is literally less than five bucks.

The machinery to make a whetsone of that same quality is more than five bucks.

they're excellent for honing carbide tooling, my old boss bought a whole stack of them from aldi on special and we used them all the time after regrinding brazed carbide form tools to get a razor sharp edge.
>traditional whetstones aren't much use on carbide.

Has anyone bought some that are truly plum? for cheap?

Diamond paste and MDF. A lot of pros recommend this over buying Veritas diamond plates.

1 micron, 3 micron and 6 micron $16 each tube.

>Simply make a strop from close-grained hardwood or MDF, apply a few drops of paste, and use it as you would a sharpening stone.

Tricky bit would be getting it to stick with glue

^ this

use lapping compound, even harbor freight sells sticks of it for a few bucks, crumble some off and mix with water, apply to surface you want to rub part against

I've done that and they work pretty well, but for sharpening thin blades without a guide they're not much good as you can accidentally carve a small chunk out of the MDF and have to start over if you want something truly flat.
There is a lot to be said for heavy vegetable tanned leather glued to thick MDF as a strop though, I use the flexcut bar on mine and it cuts fast and sharp for my needs.
The main reason I want to make a diamond plate is to have a really coarse stone for regrinding blades quickly (something waterstones don't do for me) and a fine side for quickly touching up knives and other freehand tools.
Waterstones and ceramic stones are really good for getting a nice fine edge on a blade, but for foundational grinding I just find them too soft for my needs.

The problem with hardness here is that it gets more difficult to charge a surface with loose grit as you increase it.
You could go with something like copper or tin/type metal charged with a roller bearing on a handle, but it'll still be vulnerable to scratching and be expensive if you want anywhere near a decent size.
Past that hardness you are much better off buying a cheap diamond plated lap topper and gluing it to a board of wood, it's cheaper than you would expect compared to eze-laps and the stones.

Just buy a couple of chink shit diamond lapping plates for $5.

How fine is the diamond grit?

My idea would be to make a mold big enough to fit your base, put a layer of diamond grit in there, and then stick your base in the mold with some epoxy on it to pick up the diamond grit. I'd probably clamp it down too so that it's forcing epoxy into all the crevices.

Hell, if you make a mold and have enough diamond grit you could make the block itself out of a mix of epoxy and diamond grit.

Honestly though diamond sharpening stones aren't very good. They're just marketed that way.
>>
>>1239681

Let's be serious. If a diamond slab costs $9 it's going to last 5 minutes.
>>
>>1239699
I'm not talking about charging the steel plate like you would for lapidary work, I'm leaning towards glueing the grit to the plate like the commercial ones but also trying to keep it flat at the same time.
>>
you can't really make your own diamond sharpenign plate, it has to be made industrial. if you melt your own metal and try to "sprinkle" in your diamond grit, the diamonds will just burn away.

and just gluing it to a surface of whatever material won't last longer than the cheapest shittiest whetstone you can find somewhere.

those diamond sharpening plates are not that great anyway. i'm a stone mason by profession and i use carbide chisels daily and have to sharpen them daily, and we use just normal corundum whetstones. they're piss cheap and do the job perfectly fine.

No need to lap a diamond plate, and if you sharpen enough stuff/often enough, you will need to buy a diamond lap to keep your stones flat
>>
>>1239971
>industrial diamonds expensive

Kill yourself bud

Real diamond plates have the diamond grit embedded in the metal, they don't use adhesives. That's why they last. Good luck casting something with DIY equipment and keeping it flat. In theory you could cast a metal/diamond mixture, then acid etch the metal to expose the diamonds, but fuck if I know how you'd keep it flat enough to use as a sharpener.

Diamond plates are manufactured by electroplating the diamonds onto a steel substrate along with nickel.

Your best bet is to get that steel plate sirface ground up and send it off to a local company that does electroplating of diamond tools.

Either way it should end up being a good bit cheaper than retail and you can have just about any size/shape plate you want I guess.
