Grinder belt build on the cheap

Posted on March 19, 2019 by robertwilkie

OK this is more along the lines of a build I could do (no welding involved). Its all wood based and pretty simple. Not so sure I would use a drill for the motor thought. http://www.homemadetools.net/forum/diy-belt-grinder-2×48-71538?homelistings#post128127

Nice PC fan build

Posted on February 28, 2019 by robertwilkie

I like this fan build. Only interesting bit was the author build his own PWM controller. Which I think you can pick up pre-made for a few dollars more than the parts. https://www.instructables.com/id/DIY-Cordless-Table-Fan-From-Scrap/
