I have an old der DW100 band saw. Is there a trick to switching it on
Could be any number of things. The electrical cord plug could be bad. A break in the cord wiring is a possibility. Check it over to make sure power is getting to the saw. The on/off switch could be bad. Do you hear a click when you switch it? The band motor could be worn. With the saw in the on position, tap the motor with a hammer.

What would cause my dw735 planer to not get up to speed and trip the breaker with no load on it?
The big question is which breaker does it trip?
If it trips the RCD it means current is escaping from the circuit to ground but if it trips the MCB it means too much current is being drawn and the circuit is overloaded.
The former would indicate an insulation breakdown while the latter could be a seized bearing or a serious motor fault.
The motor is presumably a brush-type for high performance in a light and compact package. The brush type motor is electrically very "noisy" and if not adequately suppressed it is perpetually trying to destroy itself and when such a motor succeeds it is usually marked by running slow, lots of sparking from the commutator and brush gear, consuming much more current and producing an entirely different sound. If it is left switched on it will rapidly overheat...
I think you need to take a peek inside.
