Julie –
My drawbench is basically the same as Rob’s. 6’ 2x6 with a piece of 2" angle with a slot cut in the upright leg on one end and a Harbor Freight strap winch (62537 ($35)) on the other. Having a removable handle would be useful for storage but having a 2-speed winch isn’t necessary. The main thing is that the winch have a strap rather than a steel cable. A cable without tension on it will tend to uncoil into a birds nest on the winch drum.
Rather than draw tongs I used a ViceGrip with an eye bolt replacing the adjustment screw and a Quick Link to connect to the strap hook.
Also useful is to mark the strap (Silver Sharpie) where the length is sufficient to reach the drawplate. I use a spring clamp to hold the drawplate to the angle.
The 6 foot 2x6 gives me a 4 foot usable draw length.
