Portable Workbench Build Process

13/3/2021

I went out to the garage this morning with a plan of doing some welding, but realised the batteries were flat on my welding helmet. I need to pop out to a shop to buy some CR2032s, but in the meantime I thought I'd do some other bits and pieces.

I started by taking the frame parts for the old prototype. I needed the jam bar in a different place, so I decided to drill both the threaded rod hole and the jam bar again (so I could ensure they were in the right place relative to one another). I also wanted to make the threaded rod hole be a tighter fit this time (it'll be a very loose fit in the final parts as the threaded rod will be held in alignment by some bushes in the wooden parts) so I could check everything works properly with the spacing set right.

I started by drilling out the central hole to about 25 mm (I say "about" as these blacksmiths drill bits are anything but accurate!)

I then spot drilled and drilled out the hole for the new jam bar, on the other side to where the old hole was.

Finally, I used a bit of tube to make couple of simple bushes to bring the hole dimension down to 20 mm again (sized to be a tight fit in the hole I drilled earlier):

I could then assemble the frame ready for the mechanism when I get round to welding it.
