diodes

Yes, it's only a lead or wire.

Actually better for heat transfer because shorter lead lengths gives a lower thermal resistance (degC/Watt  . The junction temperature thus is kept cooler which is the right thing to do.

Thanks guys, thats what i needed to know,i don't know if i will need to cut them as i don't have a lot of room inside the lumber jack accessory,i am still waiting for the module & capacitor to come ,so i can Finnish this project,i will keep you posted as to how everything turns out.

You can also shorten the capacitor leads.  They will probably be about 1" or so.  You might want to plan for the thickness of the capacitor.  If you got one that says 10x15 in the title, that's 10mm (1 cm) diameter and 15mm tall.  Presumably you'd lay it on its side - hard to tell from photos if you have 1 cm clearance.

Stan ,I was allreadythinking about that,i don't know how thick the capacitor,or the module is,so if  any of these things are to big to fit inside the accessory,then i would put everything together outside of the accessory ,cover it with some kind of scratch built building,,such as shed ,or dumpster to hide the electronics & just run the wires for the motor inside the accessory,i don't think this will be a problem ,but thanks for making me aware that i can shorten the capacitor legs also ,i already have the wiring done for power to it ,i am not going to use the switch inside the accessory,instead i have a switch on the control panel for it,this way there is no reason to reach over the track to put the accessory on.
