012 Holding up that Chop Saw (March 2021)

The chop saw found a permanent home on the old door, but that home needs a base under it. The cutting table is fairly big and I was planning to build the base using a couple rectangular frames, one for each side. Sorry I lost the “detailed” plan for this one. I was concerned that the rectangles be square as well as flat after my welding cart experience. I came across a website with a guy making trailer frames who had some good advice using a practical application of math of all things!

The theoretical: two intersecting lines form a plane which is by definition flat.

The Practical: take two pieces of straight steel and clamp them together forming a “V”. Now the two arms define a plane and any straight material that sits across them will be on that same plane. So, here we go.

The basic setup. The two 10′ long tubes laying on the new sawhorses are clamped together with a pair of steel plates. This should form a plane. The 2 pieces of tubing with the welding magnet keeping them square are each resting across both arms and therefore should be flat when they get tacked together.

We can use the same principal to add the other sides of the rectangles and they should be pretty flat.

Here are the 2 finished sides. The bench will sit solidly on four steel feet but will have a pair of castors at one end so that the opposite end can be lifted to move it like a wheel barrow.

The finished frame with castors mounted and tabs welded on the top to attach the cutting table (the door) on. More practice with the “hot glue gun”!

The frame was made narrower than the door so that it could be moved more easily on the torturous route between the basement and garage. It too will be facing an annual migration.
