The bad news is that they have parts that wear out; the good news is that you can still buy replacement parts.
So...in my infinite spare time I have finally gotten around to installing the replacement parts!
Over here we have the newer unit supporting the one
being worked on. Since the new one is a different height than the other two, it has been moved to the house to serve for home-based projects. One of the accessories I have made is a table top that can be clamped into the Workmate, it's surprisingly sturdy.
This is the one I bought new for full retail many years ago. It was stored next to the catbox for many years. One of the reasons it has taken me so long to fixing it is me not wanting to deal with the damage I caused a good tool by my neglect.
A little elbow grease, a wire brush, and some paint! Almost new!
New parts installed! Self imposed guilt trip eliminated! Pigs airborne!
