OTLEVICE is the best device IMHO
Trent,
Sorry to hear your having difficulty contacting John to purchase an OTLEVICE. His OTLEVISE is the best, most efficient and safest way to move slate and billiard equipment. I've tried many different carts, dollies, hand trucks, straps, stair climbers and sliders over the years. None can compare with the OTLEVICE for versatility. The OTLEVISE is a cart by simply clamping on an additional axle. It's the only hand truck that you don't have to lift the slate. It has the smallest footprint when not in use, I store mine in a ten gallon plastic tub. When you add the lift rod it's a stair climber!
As far as working with a helper, that's great! but you don't have to. I've moved 10 ft inch and a half billiard slates buy myself. The video is still on Youtube somewhere. The point is, you can if you needed to. These other carts and clamps require two people, especially if you are going up stairs.
I don't think it was professional of you to come onto a public forum to complain about another mechanic and supplier not getting back to you over a weekend, particularly when he has a posting on his web site about being closed down until January 2020. John has remained very responsive to all his existing customers. The OTLEVICE is one of the most valuable tools any professional mechanic can own. I know its extended my career by years. How many times has it happened to you that you need a tool or a part and it's not available at the time you need it.
John Palmer is a really smart guy that invested tremendous time and resources into the OTLEVICE. Patents, american manufacturing, constant addition of new and beneficial tools don't come cheap!
So Trent, do yourself a favor, be a little patient, stop jumping to incorrect conclusions, and take the time you'll spend researching an alternative solutions to find out what's going on. You might be pleasantly surprised.
