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.
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.
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.
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.
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.
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.

I think once you move into the 220 grit range you need to be careful with the heat!

Absolutely!!! Thank you for watching!
Does this round off the edges?
No it doesn’t
@@gentrycustomknives8008 perfect!! Thank you, this would save me litterally days of work on a granite surface block!!

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?
They get hot once you get to the higher grits
If you cover the magnets with a strip of Duct tape, it keeps scratching down and removing all the shavings is easier.
Great idea!
congrats im glad you like it i bought one a couple months back and love mine makes making damascus easy as well

It’s held up very good! Zero issues with it so far!
Can this be used for making a billet flat? Does a knife ever get stripped away from the magnet?
It works great for that. No I haven’t had one pull off yet
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.
👊👊😀😀
Air Compressor cleans that chuck up quick.
Blue painters tape will help keep the blade from getting scratched and help clean the chuck.
good to know thank you!!

wow i like that i dea i just bought the same surface grinder attachment from OBM about 2 months ago i love mine makes damascus a breeze
Can you make the magnet thingy pivot a little so you can do tapered tangs with it?
Yes!
@@gentrycustomknives8008 Sold! I'm getting one.
Can you adjust the angle so that you can do a tapered tang on it?
Yes! I haven’t tried that yet but it’s doable
Great video, thank you.

What size is your tooling arm?
@@gentrycustomknives8008
They use a 1.5inch square tube, .25 inch thickness. I was thinking I could just drill and tap to match?
Correct! This bolts right to a standard tooling arm which is what Brian uses
ok
That is sweet!!
It’s so nice!!
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.
It’s holding up just fine!
I ended up going with the ameribrade surface grinder.
@@johncollinson196 nice! Let me know how you like it! 👊👊
@@johncollinson196 Hows the ameribrade? I'm looking at all the surface grinders.
@@griftopherhitchens9926 I love it, the switchable magnets are definitely where it's at.
Would it work on the TW 90?
I believe so, does it use 1.5” tooling arm?
Congrats buddy
Thank you!!!
U great sir
Thanks
