 Building a gantry
Not exactly centrifuge related but we recently built a taller shop gantry for lifting in the taller parts of our shop. We needed something that could lift a 500 lb furnace into it's final resting place.
I started with a wall mounted crane that a friend gave me a few years ago. None of our shop walls met the engineering requirements to install the crane. After a few years of moving it around I decided it was time to do the unthinkable... and cut it down and make a gantry. Next I cut all the steel. I pre-drilled two top plates.

I clamped the top plates to the underside of the I beam and drilled 1/2 This is the drilled I beam. The other end was drilled the same. This is how the top plate will be welded on.

This is the top welded into place. This is a set of old heavy duty wheels I bought at the flea market. I welded the wheels on.

I also decided to weld some simple hooks on the top of the I beam to make it easier to lift. We lifted the I beam up to the ceiling using a some pulleys from the hardware store. The pulleys made the lifting effortless.

After we installed the uprights it was discovered I had made the uprights too tall... I forgot to subtract 3 inches. I guess I was in a hurry. We cut off the tops and removed 3 inches. Clamped everything really good and welded the top back on. Now the gantry can clear the lights by an inch.

Here we are lifting the furnace into position. The gantry worked perfect. Not bad for some scrap materials.
