SURFACE GRINDER attachment for 2x72 belt grinder!!!!!

In todays video I go over my new OBM surface grinder attachment I just received! this tool is absolutely incredible and will definitely save me a lot of time!

If you have learned anything from my videos please take a second to check out my apparel and pick up a shirt!

p.s. the surface grinder normally ships with a 70 duro wheel but in this video I'm running the 90 wheel which will give a better surface finish.

congrats im glad you like it i bought one a couple months back and love mine makes making damascus easy as well

Sweet! Thanks for another great video. I built mine and I totally agree it's one of the best tools in the shop. If you take your mag chuck off and tape up the sides real good, you can pour epoxy resin to fill the gaps (then just resurface). Makes it a breeze to blow off the dust with the compressor. By slapping on some double-sided tape you can also flatten scale material, liners, bolsters.. sky's the limit! Try out the 3M 337DC Gator belts on these, puts a nice clean no-hand-sanding final finish on the flats/ricasso's and handle portions.

Well you should be excited, how cool is that to watch make the blades straight and with such a clean finish. Way to go, enjoy. Lance & Patrick.

Been looking for a good surface grinder solution for a while. Will definitely look into this when I upgrade to a bigger grinder. Currently, I've found my best solution in a precision flat aluminum plate with 2.5" sticky back rolls of sandpaper and hand sand them but damn that can take forever sometimes. I don't recall you mentioning this but to anyone wondering what the importance of precision flatness is — have you ever had weird dips or unexpected results in your bevels? It's almost certainly because your steel isn't flat.

Air Compressor cleans that chuck up quick.
Blue painters tape will help keep the blade from getting scratched and help clean the chuck.

Wondering if it would heat up the blade so much to ruin the temper? Especially on thin Chef knives.
Since you can't really dunk it to cool it off as you're flattening it.

So here’s the story. Travis Wuertz thought up this design & started making & selling them over a decade ago. The minute I saw his I wanted it. However, I could not afford the price tag. So I went to work. From pictures & videos of his, I found the parts used, mainly the linear guide rail & Powerful Neodymium magnets to make a Mag Chuck. And found them at very affordable prices. Then reverse engineered & built my own. I was the first to build a copy of it & made the huge thread on Blade Forums. I did it for DIY’ers, like me. But the next thing I know, a bunch of places are copying the reign to sell. That was never my intention. Origin Blade here never designed anything! They saw my thread like everyone else. But they claim it as their own. Was never my intention for people to steal Travis’ design for their own. Only for people like myself who couldn’t afford the expense, but had the know how.

Can you make the magnet thingy pivot a little so you can do tapered tangs with it?

[billclancy]

If you cover the magnets with a strip of Duct tape, it keeps scratching down and removing all the shavings is easier.

[davidcoalkey]

Can you adjust the angle so that you can do a tapered tang on it?

[pizatio]

Can this be used for making a billet flat? Does a knife ever get stripped away from the magnet?

[noahrockland]

This thing looks awesome. How do you prevent heat build up for the hardened steel while using this? Or does this not build up a ton of heat?

[erikbullard]

Great video, thank you.
Is it possible to use a different tooling arm for this? I just built a Revolution from Brian House and was curious if it’s as simple as unscrewing and remounting on a steel tooling arm.
Keep up the videos, they are extremely informative and helpful.

so after a year do you still like it? I'm about to purchase one and have been trying to figure out which one I want to go with.

How well has the surface grinder attachment held up over a year of use? Did you find the $900 worth it or do you think it's worth the extra for another brand? I absolutely love my OBM, and I'm thinking of buying the surface attachment.
