Like most other people here, I research the crap out of equipment before I buy it. I've seen enough info on 9" disc grinders that I feel comfortable buying one. I received approval from the boss (Oxana). I have seen makers use them for bevel sanding (Nick Wheeler), flat sanding (Ekim Knives) and scale sanding near the blade prior to attaching the scales to the knife. Any other uses? I do not have a surface grinder so maybe something there?
 
If you have access to water jet, plasma, or laser cutting steel, talk to Kevin Powers. He’s a member here and is also on instagram. He designed a great table that will save you hundreds of dollars.

I know recently he sold a few for CHEAP! The tables are well thought out and very useful.
 
Have a look at Rod Neilsen Magnetic disc grinders. It may be a bit more expensive but very convenient in use. Some folder makers are using these exclusively.

Get one. I delayed buying but now i have no idea why.

I would advise you build one from "parts" that is to say buy the Motor and VFD from ebay/ amazon/ automation direct and the disc and base from tru grit https://trugrit.com/index.php?main_page=product_info&cPath=69_96&products_id=5928

I'm not at the point where I am using those services. I will check Kevin out though. Thanks
 
get an 8". more choices when it comes to buying the head and discs. 8" for whatever reason is size of choice for lapidary and metallurgical lab disc grinders. a basic 8" head will cost about $55. a fancy work surface with miter gauges is nice but not necessary. yes the magnetic interchangeable heads are so cute, but it takes 10 seconds to change discs. when making smaller knives, i use the disc sander to fine sand before and after heat treat. I use a 1Hp 1100 rpm fan motor that runs off the VFD. shop eBay for 8" PSA discs, someone always has some on sale. 8" also works for cutting your own disc from sheet sandpaper. make sure the disc head has a rubber layer, easier to get the disc on and off.
 
This is what many knife makers use and what I use in some way on every knife I make. It has a Rod Neilson disc system. Larry

I settled on both. I think it was Geoff Flato who inspired me. I have a 9 inch disc for metal work and a 12 inch for woods/synthetics.

For the 9 inch I use a cork backing and rhynowet paper and for the 12 inch I use thicker sanding paper. Both use feathering adhesive for quick grit changes.

How do you like that Bosch drill press? I have seen one on sale and it looks like interesting, would you like to share your feedback about it?
Sorry for hijacking the thread :(

Well, if you know Bosch tools, you know they should be blue. Which is their professional series. Unfortunately they don't make any drill presses in the blue series.

So I settled on this one instead of the more classic drill presses on the market, which here in Sweden either means really low quality underpowered China crap or the old Swedish Arbogas, which I unfortunately don't have the space for.

But all in all, it has served me well for about three years now.
  • It's relatively well made, has pretty good power (710 watts) and it runs pretty true.
  • I've made some pretty large holes with it, up to around 1 inch (in steps of course).
  • It's got a nice built in clamping system with I think work great and clamps your stuff quick and easy.
  • I really love the electronic speed control, it's a very slick feature. Also the digital depth gauge is a nice touch.
  • Of course the press lacks some rigidity, but for smaller holes it's a great unit!
Now I primarily drill on my mini mill, and I use this one for chamfering and other quick, repetitive tasks.
