Homemade Surface Grinder Attachment - Want Flat Things?

This video outlines everything you need to know in order to build your own surface grinding attachment for your 2x72 belt grinder. A surface grinder is a really nice item to have in your shop, however, to buy a stand alone unit you'll be out some serious cash! Travis Wuertz invented this type of design and many in the blade making community have made their own renditions. For around 450-500 dollars you can build your own SGA!

I have been wondering about getting a mill for flattening out surfaces on forged pieces. Since you already have a mill, do you find the surface grinder attachment better for this type of use? Faster/cheaper/easier/other reasons?

@RedBeardOps 3 жыл бұрын

Good question Joe. Yes the Surface grinder with belts will be much faster. Clamping forged pieces on the mill can be difficult as well. I do use the mill with a router bit to flatten handle scales and blocks though.

@subzero5101 3 жыл бұрын

I use my surface grinder attachment on forged pieces as well especially since I do a lot of salvaged metal knives and swords. You can never be 100 percent sure how hard the metal is after forging. Some metal air hardens quickly. Even a draft from one side can make piece hard enough to waste a 50 dollar bit by hitting just one little area that got hard. I also agree with the clamping issue. It's sometimes hard to find a reference plane to start with on something that may or may not have warped as it cooled. A mill is still an indispensable tool where exacting tolerances are required however forging is not an exact science.🤔

Congrats! Looks great! I wasn't as patient as you I just bought the Origin Blademaker surface grinder. Got it last week. The surface grinders will really up our games. I have already found as you were doing it is of the utmost importance to true it up before you start using it. For me I ordered some 2 1/2" belts. They're easy to find. Good luck. I am anxious to follow your progress here as we both seem to be starting this part of the journey at the same time. Next is figuring out how and where to store it when not in use. It is a big burly thing and attracts a lot of metal dust (as it's magnetic). I need to find a way to store it that it doesn't accumulate metal shavings when not in use.

Awesome Jim! You'll have to let me know how the OBM works out for you. I think I'll be able to use some 3'' x 79'' belts that most people carry. I've been playing around with it over the last few days and it's promising! I'm thinking of storing it on the wall via hooks.

@salvadorebertolone 4 жыл бұрын

you cant really. flat is a reference to a plane. normally you would measure this against a reference surface. most times you would rub a surface against a reference to pick up ink and then sweep the low spots with a test indicator to understand the deviation, you can also raise the part off a surface plate and level the surface being measured and then sweep it with a a test indicator. whats actually being measured here is parallelism.

@@salvadorebertolone I think I've seen that before. The process is called "scrapping" right? They get stuff extremely flat!

@salvadorebertolone 4 жыл бұрын

@@RedBeardOps yea, but they usually aren't taking measurements during scraping, often they are just knocking down the ink until the have a certain density of spots. You can do the same on a grinder, it will be very good at making something parallel, but it will often pull a part flat on the magnets, to where it's parallel but isn't flat, with some practice at grinding and after you've flung a few parts off the magnet, you'll learn how to grind with just the residual magnetism or how to shim the part so its pretty flat

@@salvadorebertolone I have for sure noticed this. I've been messing around with shimming my parts if they have a warp out of the heat treat. It seems though that getting my warps out in tempering before heading to the SGA is the best place for it, since the shimming seems to be a tedious process.

Thank you for sharing, question you did not show the bar adjusting during your first grinding, so you do not need it? what is the purpose of it, thank you and have a nice day.

@RedBeardOps 4 жыл бұрын

Hello, sir. During the initial testing I have the bar set in the "maxed closed" position so that it rest against the stop nut. This will be the position in which the chuck is trued up to the wheel and where I'll do most of my flattening. The adjustment of the arm is primarily for tapering tangs. In this case a specific shim will be placed in between the arm and the stop nut in order to achieve a specific tapering angle for the tang.

@mrcwarnett 3 жыл бұрын

Cool built, I like the idea, not as precise as a full surface grinder, but I expect it's plenty good for what it's meant for. Couple of thoughts while watching, if those locking levers are used enough you might end up with the threads wearing out in the aluminum, if so a thread insert (a Heli-coil for example) would be a perfect fix. Interestingly aluminum can be cut with woodworking tools, if I had the choice I would have cut the slots for the magnets on a table saw, not always an option (gotta have easy access to a table saw...) but it opens up possibilities. You may know this already but those screws are generally hard(ish) so they tend to wear the blade on a band saw quickly, especially if the blade is new. As a machinist, I feel you on the milling for the first time, it's a totally new game, wildly different rules, so no harsh judgements here. Great build, I look forward to hearing your thoughts and experiences as you use it more

@RedBeardOps 3 жыл бұрын

Hey yeah Curtis, for what we "full tang knife makers" do it's more than adequate. For sure not a replacement for a legit surface grinder. Very good points in your comment. The table saw would of been way faster I bet. A lot of machinist have commented on this video in what I'd consider a mildly-hostile way; so I really appreciate your approach. So much to learn on my end! Cheers sir, have a great weekend!

Nice job, pretty impressive. It'll be interesting to see how the epoxy holds up... A surface grinder was my 2nd big purchase(cost more than my grinder). On the Travis Weurtz SG, the magnets are in a metal base. I can't pull them up, but i can slide them out(if that makes sense). Also, there is a place to mount a dial indicator on the slide table(though I never use it, to be honest). Hope all is well, take it easy

Nice project! (I plan to make one myself someday). Is there a specific reason you put the slider vertical? Some use it more horizontal to get some view on the grind and maybe safety if the blade comes of. Greetings from the Netherlands, a fellow maker and (a little less) red beard. Bart

Cheers from Texas sir! I put my vertical out of ease. One day I'd like a horizontal grinder and when that happens I can use this same attachment and have it horizontal. As far as the function goes it seems to be about the same... just a little more work to use. If you throw a blade off of this chuck you're taking waaaayyy too big of bites! This chuck is strong!

@waynethomas1726 4 жыл бұрын

You may have covered these questions at some point in previous videos but this is the first one of yours I've watched. Great vid! Is that a home made band saw? I'd love to have a metal cutting band saw but a good shop quality one is pretty crazy expensive for my little bit of work. A wood cutting badsaw just doesn't seem to be either tough enough or will it run slow enough for cutting steel. I've considered buying one of those portable metal cutting band saws and rig up a way of attaching it to a table. Is that what you've done? Also, what I find really handy for transferring hole locations is they make a set of transfer punches that have a punch point on an accurate diameter shaft. I think China Freight sells them but I picked mine up from a yard sale. They don't help much on thin sheet metal as the point on the punches are like about .030" or so. But on material at maybe 1/8" or greater thickness they're super handy and the "divet" left behind is usually big enough to center a small drill. How do you like that automatic center-punch? I see it leaves a good mark on aluminum but does it leave a good mark on steel? I keep threatening to buy one and was curious as to your opinion of them.

@RedBeardOps 4 жыл бұрын

Yes sir for sure! However, an easier way would be to rotate the whole belt grinder counter clockwise. This is actually a very common feature that many modern 2x72 belt grinders have. Mine just doesn't! One day I hope to have this built into my machine. By doing this the assembly would be rotated 90 degrees and way easier to use. All that being said; It really hasn't been that much of a challenge to use at all in this orientation.
