Homemade belt grinder

You REALLY have me thinking here.

Soooooooooooooooooo

If it's not a lot of trouble I'd Like to see more pics of. and know more about, your tilt mechanism design and what materials you used to fabricate this.

Thanks

Thanks
Here are pictures of tilt mechanism.. it's basically a hinge made out of a pipe of the same inner diameter as outer diagonal of square tube, squeezing the tube. It's rock solid. Welding is not the greatest, I have an old arc welder, if I had an mig welder available , it would be better







Here is my trial grind. It's my second try on this machine.. first I won't show :D. It's almost free hand, I used a tool similar to Bruce Bump's grinding jig for plunge cut. Mind you, blank was a lot bigger when I started :o :D

 
Thank you, thank you, thank you, thank you, thank you, thank you.................

That's a nice piece of DIY design and welding IMHO. Simple and really sturdy.

I'm definitely gonna steel, errrrrrrrrrrrrr, steal some of your ideas when I convert my Bader to a tiltable tool. Methinks that will ultimately save me, perhaps $1200.

A 115 mm drive wheel is about 4 1/2 inches and on the surface feet per feet calculator online at 3800 rpm it delivers 4477 surface feet per minute which is pretty fast. Larry
 
Thanks mr. Bump :)
Larry, so my math was good.. 75 FPS times 60 gives 4500. The controls for the motor are rigged in a way that every time I turn on the machine, it goes from the slowest speed (I don't have the means to measure that, but I will guess 300-400 RPM) and then I can speed it up. Variable speed is really a good thing.. I know that this machine will be a huge improvement for me, till now I had small hand held sander witch I was turning upside down and held in a vise :rolleyes: this is a whole new level :)

Excellent Job Vladimir !! Lot of grinder envy , And nice job with the filter for the motor . It appears that you really thought this whole thing out really well. I started the same way as you with a old belt sander upside down.
 
Glad I saw this. We finally got a new treadmill, so I latched onto the old one. Now I just need to find the time to get out there and pull it apart. Good inspiration.
 
Sparrow, Excellent work, excellent design :thumbup:
Your 90° tilt feature is the icing on the cake.

Again, Nice job !

:cool:
 
Thanks
@medicevans, if you have any questions regarding build, feel free to ask, I will help if I can
 
It's been a couple years since the "unveiling" How is the grinder running?
I'm impressed with the design!
How did you cut the arc on the tilt adjust?
Does the square tube carry straight through the support pipe, with circular flanges welded on each end of the "clamp pipe"?
