Hi another question about weapon activating with the electronize 2 way switcher , what sort of relay would i need for my weapon , it runs off 24v so im guessing ill need a 24v relay , but what type ?
Also if somebody could draw me up a quick diagram of how i would wire the whole thing up aswell that would be great .
I have updated my design for my spinner , It is basically going to be like an old version of little spinner ,
I have recieved and old angle grinder gear box that i am going to modify to attach a gear that has the same pitch as the ones found on drill motors .
I have also bought 2 johnson motors to power the spinner and going to try and find some old pinion gear on some small motors .
I also got the elctronize 2 way switcher for the 2 johnson motors . The hole design is going to be an undercutter of some kind with a 4mm hardox bar with 8 mm hardox teeth on the ends
Any comments on the design would be great .
We used 12V relays at 24V in little spinner 2 (version 1), mainly becsue we had some spare but didnt have any problems. Actually one of these is now in Dizzy Tilly and thats working on a mag. Not bad for a relay that says its rated for 12V 10A. Little Spinner used a 75W pancake motor and belt drive.
i still have some 12v 80amp relays, that arnt bigger or heavier than the relays used to modify the 30 amp electronizes.
its the HG4185C from willow technologies, make current is 240 amps, break 80 amps. weight about 35 gr
I have some questions about pinion gear
What is the Module of a normal pinion gear on a drill motor ?
What is the pitch of the gear on a drill motor ?
What is the Module of a normal pinion gear on a drill motor ?
I think it is 0.75.
Thanks JH-Q i just figured that pitch and Module were the same thing
Can somebody please post or draw up a schematic diagram of how i would connect a 12 vlt relay to an electronize 2 way switch to turn a motor on or off
To make a motor run in forward or reverse you want a pair of SPDT (sometimes called SPCO) relays connected in an H bridge. Maplin does a good 30 amp one for £1.49. The electronize switch turns one relay coil on for forward, the other on for reverse. For each relay pair connect your motor across the common terminals, connect your battery positive to NC of both relays and your negative to NO of both relays. If this is hard to follow then wire up the relays, without the electronise switch, and turn the relay coils on and off with an ordinary switch until you are confident about how it works.
Thank you John i understand how to wire it up now thanks
I have a question about the mod size of a gear , JH-Q told me that the mod of a 9 tooth gear you find on the end of the drill motor is 0.75 , i cant find any gears with a mod of 0.75 , what do i do ?
This is my planned weapon setup

Am i right in thinking that the total ration for the setup is 9:1 ?
What do people think of this setup ?
looks like it will work ok, i would strip the angle grinder gearbox, degrease it, and replace with a light oil like wd40. thats just me though, minimizing the friction losses
