I currently have a 6mm thick tempered glass as my main panel but I stuck a plastic protection film to prevent the glass from fogging up.

    I am in the process of building a sand blasting cabinet, but have been having issues with the abrasives getting sucked into the extraction fan. The fan is too powerful for my cabinet, so I got a VFD to slow down the extraction rate so that only the dust gets sucked in, but I'm still having a...

    Syphon blast gun issue

    Been having trouble getting the triggerless syphon blasting gun to work how I want it to in my DIY cabinet. The issue is with media suction.

    I recently purchased a used hydraulic piston thinking it was a pneumatic one and although it wasn't my intention, I have found it to be excellent for my requirements. I would like to make a can crusher using a pneumatic piston but the hydraulic one works perfectly well. It moves very fast in...

    I have a brand new electric motor I bought to build a belt sander and would like to change its factory color of green to a light grey.
