Doug S said:I guess it's for safety reasons but I would like it if there was some way of locking the Kapex on so you could leave it running when making multiple cuts. I could be wrong but the constant on/off cycles with the soft start and the electric brake kicking in must cause a lot of heat and can't be good for the motor where a constant running motor might run cooler? If I'm going to be making a lot of cuts I turn my extractor on to manual and just leave it running, it seems better than it cycling on and off every few seconds with the saw.
My radial arm saw can run continuously. I can set 5 or 6 pieces of 1-1/2” wide material against a stop block and cut them all at once.
But note, a poorly maintained RAS is possibly one of the most dangerous machines in the shop. This is a problem mostly brought on by the marketing people at Sears. When you visited the woodworking shop area of any Sears store there would be a RAS setup and the head would slide as smooth as silk. But that was usually because they set the bearings too loose. In the real world, a saw set up as loosely as that ran the risk of climbing the stock and rushing back at your chest.
Mine seems noticeably less fluid, and is less risky to use.
But if precision is required, not only does the stock have to be solidly banked against the stop block, it must also be clamped against the fence and (probably) clamped flat against the saw’s table.
You can spend serious bucks and get both speed and precision with automatic feeds and automatic clamping, but otherwise you have to balance the speed/precision aspect.
