Tony: I meant to ask you- on a motor like the HTIs or the mini EVs, which have a really skinny motor shaft, whats a sensible way of attaching drive pulleys or sprockets to them securely?
Most people use grub screws but I have welded mine on to the shaft but you have to be very carefull, cover the motor so not to get any bits inside. Dont try to weld it all at once as it will get too hot and could damage the motor.
Thanks Tony. Initially Ill be using the RS pancakes, but the prices on mini EVs and HTIs are low enough to encourage experiments next year...
If the shaft is 5mm then the trantorque keyless fitting is very good. RS sell them
I didnt want to make a new thread so ill just post here , I want my wearpon motor to turn on , and i want to build a mechanical switch myself , i mnow i would need a relay , a microswtch and a servo , but how do i wire the whole thing up ? The weapon motor im using is one of the pancake motors mentioned in the for sale section , any help would be great .
Sorry for the double post , But i have had another though , would it be easier if i just got an electronize rc switcher and a relay and it woould just turn the weapon on/off , Would this be easier ?
I like your idea of an Electronize RC switch activating a relay.
On DragonStrike I use a servo connected to a toggle switch to turn the weapon on/off simple and cheap but it works.
Only problem is that it doesnt failsafe TonyEasy way for me is to use a PicAXE 08M or my IBC
It does if you add a failsafe between the servo and reciever £11 for the failsafe £2.50 for the toggle switch Like I said cheap
