Wow, 58 pages of enthusiastic B&D Workmate chatter! Who would have believed it?
I have had a couple of them, (UK) an early black one bought in the late 70's or early 80's, which I probably sold for a song, I have a vague notion that I'd stopped using it anyway for some time but it's so long ago I can't recall the reasoning.
The other I've had for years, a blue 2 level, ply top. I have no idea what model it is, or until I looked that there are sooo many variants. It stays in my work van & I find it very useful, so as a result it's a bit rough & knocked about.. A while back I managed to saw the grooved face / nose off one of the jaws & also a bit off the end. That is busy jobs being rushed to get done. (& sloppy work practices!) I made a new set of ply tops for it years ago but never fitted. (I recall finding it impossible to undo the fittings but haven't looked at it since) Might have to have another go since I find the jaws less functional without the groove on that side. I could of course just put a new groove in.
I strongly wanted an original aluminium model after seeing one my workmate had but they seem to fetch quite high prices here. In the end, they are just a tool & to my mind don't justify silly prices, although that said, I do like originality in design. I suspect that the steel ones may actually be a better bet, having seen an alu' one with broken frame. Steelies usually are just missing leg catches & top locking side springs, both easily solvable.
The particle or MDF board tops on later workmates were a retrograde step. OK if kept dry I guess but quality ply is so much better.
