The Hovercraft Table I built is working very nice but I wanted to do more than just drive it around the workbench. What I want to do is move heavy machines easily from one bench to another.
I will start with my drill press table but since it is lower than my
workbench I will have to raise it.
I measured the table and it is 61.70 mm. lower than the workbench
so I will have to add larger wheels and some blocks to get the
To make the blocks I glued some scrap plywood together to
get a rough height. Later when I add the wheels then I can
make some fine adjustments by trimming the blocks a bit.
Since I work with pianos I get many casters. These are the ones I
will use. I first fit an insert sleeve into the block and then press in
the caster. Very easy system.
I placed a small piece of plywood on the wheels and with a caliper
I was able to take a measurement of the 4mm. gap shown in the photo.
The blocks and wheels are not attached yet so I then proceeded to
cut 4mm. off each block.
tables are the exact height and I am ready to test it out.
On my first try everything worked out great. It floated from table to
table. I can now try other machines!
