@@DktheWelder you can edit the whole shape and change pitch angle manually. Worked well for gears i printed for a chainsaw power rc car using bicycle chain and they've held up well.
thats awesome! As for the alum strength, it will be there but its the wear you gotta worry about. The teeth will wear out faster and get loose causing chain slip etc
The money for quality sprockets that large is nuts. Just buzzing out another once it wears a bit is awesome. You might want a different ratio later anyway.
I don't really know much about this, but if you keep your chain properly oiled that will help the sprocket last longer. I wonder if there's a way to heat treat aluminium that you can do with a blowtorch or something simple like that.
Might want to have a go at precipitation hardening the aluminum. I would almost think you could work harden it by smacking or pressing the chamfer on the teeth instead of grinding it off. Pretty sure cryogenic hardening works for aluminum also.
Yeah I have been googling stuff about it , but I still think the aircraft grade stuff would be the way to go. It might work harden itself a bit hopefully. What is cryogenic hardening?
Don't do what I did when taping up the trigger on a power tool...put it back on the shelf and forgot to remove the tape! 2 weeks later placed it down on a countertop, plugged it in and watched it fly right across the counter leaving a trail of splinters and destruction!
Nice one bud. FYI, there's a gear add on you can download for fusion 360. You just add your teeth # and pitch and it will draw it for you👌
Sprocket gear calculator.
Works a treat
Yeah I have seen that but I don’t know if it can get the sprocket shape. Could help out with spacing though. Have you tried it?

@@hyster16t ok cool I will have a go at that thank you

Yeah that aluminium is a lot softer than the proper stuff
Your awesome Christo. Thanks mate
Hardening, or rather "aging" aluminium is pretty easy and you can do it in your own oven.

Yeah I could just trace around the one I made 👍
I like this idea. Way faster then trying to make one on a manual mill!
Also once one is made you can just trace around and make heaps
@@DktheWelder yeah good point!
Epic bro! It chewed that alloy out quick!
Thanks ! It makes a mess!
Nice to see it can be done. No fear !!!
just like that hay sprockets made brilliant mate keep up the good work
Hay sprockets? I will look into that
Interesting, thanks for sharing how you did it. 👍

I have been googling it but don’t think there is an easy way . I could buy some aircraft grade aluminium but I will see how long it lasts first
I need to see that machine
Great method

@@DktheWelder to cryo harden you basically bathe it in liquid nitrogen. Works for almost any metal for a nice hard surface.
We all need a friend like you,nice work lol
👍
Fu##ing awesome bro

That does sound funny but dangerous!
GET THIS MAN A CNC CUTTER
Yes that would be great!
Cool thanks for the vid!! I am looking to make an 72Tooth #420.. do you know i can i find The sprocket gear calculator ? Thanks! Subscribed !
There is a gear calculator on fusion 360 but I think I showed how you can figure it out in drawing part of the video?
Ok thank you :) @@DktheWelder
Haha I just used that exact router and a flush cut bit to widen the center bore of a set of calais wheels to get them to fit a commodore.
They chew through the alloy so quick aye
You sir are a genius thanks I literally need to do that
@@jackbeets3838 thanks again for the motor jack. The sprocket idea worked pretty well aye
Sweet as awesome to see it living to it's full potential again
Not bad at all I've made one by hand once not as easy as it looks
I made one by hand when I was pretty young it was so far off it didn’t work haha
@@DktheWelder yeah they need to be pretty spot on
which software you use for design, that can be helpful .
Fusion 360
@@DktheWelder thanks bro!
were can I get a machine
What metal is it made of? If thats steel that will blow my mind
It is aluminium. I have an idea of how to make a steel one maybe make video on it one day
@@DktheWelder Do it!
What kind of bit did you use ?
Just a wood bit with the bearing on the end
Do you have the stl file you made
I do , no one has asked for it I will but it on my CG trader for free later once I’m on the computer
Noice.
Amazing sh|t gets done in Kiwi sheds :)
I love being out in the shed 👍
