Variable speed 9" disc grinder build

The last step was getting the magnets pressed into the hub. I used two staggered bolt patterns. Notice the jacks under the hub. On the first hole the hub rang like a bell so I needed to stiffen things up a bit.

With the 12 magnets installed they have a combined force of 96#

An absolute display of fine craftsmanship Brian. Great job. Are those pennies between your clamps and the workpiece to prevent them from being marred? A good thing for me to learn and remember.

Looking forward to the video.

Yes those are penny's. And that is what they are for. I wondered if anyone would notice. Good eye!

Thanks for the compliment! !!
 
Absolutely a great job! Thanks for taking the time to document and share it.
 
Brian, that is one fine job. The magnets & quick change plates are a really slick idea! Thanks for posting this build. I can imagine being able to change the grits that fast will make this machine a pleasure to use.

Hi Brian

I really like your 9" disc grinder build, I only have one question at this time.
Do you have a set of plans for this grinder, I would be interested in purchasing a
set if available.

Thanks
