So the workmate boards had to be removed, and put to one side, until I can replace them.
The photos tell the story, there was one more glitch, which I still can't account for, that was during the process of gluing the top and bottom 3/4" boards together, they moved, how I have no idea, because they were clamped, but move they did, I did not notice until the glue had dried, I had also screwed them as well, now I have a second blade slot! However if I decide I need to widen the current slot to be able to cut at angles, then this will incorporate the second slot.
The saw is attached from the underside with a screw front and back.the saw has to be wedged in the 'On' position, the only way to turn it on and off is with the plug, so I wanted extra safety features in case the vibration caused it to drop out, I have installed some wooden toggles to ensure my feet are safe, long enough for me to unplug it.
The good thing about this design, is that I can remove the saw, lift the table off and prop it against a wall, and collapse the workmate, if I need the space, all in a couple of minutes.
When we eventually move, and I no longer need this saw, I will re-instate the workmate, and the now, 1 1/2" plywood top will be turned into wooden bar clamps, so nothing wasted!
