is this inspired from that harbor freight lift at a home where we had no idea how to modify that wacky handle setup?
I used the Casters wheels on mine, remove the wheel, drill a hole through the post and connect the handle to the top of the caster with u-bolts. No welding required, been using it for 3-4yrs, make live much easier.
I have one of these I picked up from Andrew at Twisted Quarter in January and love it.http://www.twistedquarter.com/index.php?main_page=product_info&cPath=82_246&products_id=1315
