    Re: Moving machinery with a Pallet Jack

    Well, I started this thread a DECADE ago! I've had many machines (mills, lathes, surface grinder, etc) and moved each into and out of my garage, even moving houses a few times. I just finished...

    What happened

    The short answer: I sold the Bridgeport Boss after I had it up and running on Mach3 with the huge servos.

    That was a few years ago. In 2007, I moved to a new house on 2.5 acres, hoping to...

    I recently needed to replace a missing part on my Case 580 backhoe - a simple hose bracket. In the spirit of DIY, I opted to save $50 (or whatever that part would have cost from the dealer) by...

    A few years wiser

    Well, I started this thread a while back, when I was still trying to find a way to get machines into (and eventually back out) of my garage.

    Most of the trouble comes from two problems:

    Yes, indeed that does help! Curious why they would use a tachometer _and_ an encoder in tandem. I might just pay a visit to US Digital (they're located just a few miles from here) and see about...

    Move-out of SL-1H

    A few photos from my move-out of the SL1H.

    I rented a 8000lb Gradall forklift based on past success. It's a great way to maneuver off-road and into small door height garages. For those curious,...

    Home Shop Machinery Moving

    By the way, making your own machinery skates is not hard. Who says you have to use expensive Hilman rollers? I made mine out of 5/8" drill rod TIG welded to 1/2" plate. The drill rod is a cheap...

    Rotary Phase Converters

    Well, I learned an expensive lesson - don't shut off your rotary phase converter before you turn off the Mori.
