Tool David's 2x48 grinder build

Tool
Now you have to add the grit collection so that your grinder looks ‘shiny & new’ forever.
Nice work David
So far my work consists of sending the file to the laser cutter dude and then driving into the wilds of Vancouver Island to pick up the parts.
I’ll try and do a decent job TIG welding it together :)
 
David - hope you don't mind a bit of a hijack here, didn't see a reason to start a new thread.

Here's my grinder, outside of the colour it looks pretty much like the video. The only thing I added was an DPDT on/off switch for the 240v as the VFD doesn't have an on/off button.

Even with a 1.5hp 3ph motor it doesn't take a heavy push to bog it down but otherwise it does work well.

Nice!

I have that same vfd on my lathe, i dont think it is sealed, might want to put some kind of filter material over the ?ports?vents? All that electrically conductive dust youll be making might find its way in and burn the vfd out

Nice! Really going to have to pay a visit one of these days.

Um……….run/stop ? Am I missing something ?

Although I'd guess that they exist, I have not run across a VFD that has an on/off yet. Run, Stop, Reverse - yes. On/off - no.

A switch in the input power line is simple and serves that purpose well.
