Once the hopper was done (I can’t say that without thinking of the Dish Network commercial) I moved on to building the sand blast cabinet.
The cabinet will measure 5′ wide x 6′ high x 30″ deep. Back in February I picked up 16ga sheet that I cut out the panels from. I struggled with how I was going to build the cabinet until I came across the idea of building some scaffolding. It’s not an original idea, it’s just how I chose to put it together.
It started with building a wooden framework that I could clamp the 16ga panels to. In this photo I’ve placed the door frames against the scaffolding to make sure I had the dimensions correct.
Then I began to hang the sheets of metal. There are the rear panel, top, window, front panel, two side panels and two legs. Here’s a picture showing everything but the side panels and the legs tacked together.
I created another framework to support the hopper while I moved it into position inside the cabinet.
Next step was to build the legs. If I was to do this all over again I would make the legs and the front panel from a single piece and cut out the front opening. It started with laying out the 16ga sheet, using a straight edge and the plasma cutter and cutting out a piece.
Then once I have a piece that is the correct overall dimensions, I need to reduce it down by cutting the angle for the legs. The legs are about 2′ tall with a taper from 20″ at the top to around 8″ at the floor. This is around a 60 degree angle. So using a straight edge and the plasma cutter
I end up with this shape
and using a set of butt joint clamps, I can clamp it to the rest of the cabinet.
The side panels were cut out and drilled that I’ll use to weld the leg panels to the inside of the door frame.
In this picture I’ve clamped the side panels to the door frame prior to welding.
Here’s it’s all roughly welded together before inserting the hopper.
