I reckon you'd churn out an MDF one in no time

After a few days of kicking myself for not being able to workout how the heck to use those gear pattern generators.
I decided to go back to my low tech method and do it the old fashioned way.
I draw up a 180mm circle with 88 divisions on it and drilled some holes.
Then market in the teeth and started cutting on the bandsaw.
So far I've only cut out a 1/4 of it just to see if it was going to work.
The teeth themselves are only 5mm high which makes it a little fiddley.
But it seems to be working quite well.
I'll keep cutting away tomorrow and hope I don't make to many mistakes.
But it's not as if it needs to work so any mistakes should be able to be fixed with bodyfiller.
Cheers
Trev.

So far it looks like a real one from here. I hope you progress through the rest without any trouble.

Thanks mate,
Using 3mm MDF to make the sprocket is working alright.
But the bandsaw maybe a little to much for the job.
I have a fairly fine blade on it but it is still tearing the edge of the MDF a little.
I think before I cut the rest of the teeth I'll run some super glue along the edge.
It gets into the MDF quite well and makes it a lot stronger cutting down no the tearing.
We'll see how it goes!
Cheers mate

Here's as much as I've got done today.
The idea of running super glue around the edge of the MDF worked a treat.
I had none of the previous problems with the MDF tearing.
I drilled out the rest of the holes and cut the MDF down to size.
After drawing all of the lines and angles by hand I think next time I really need to learn how to use one of those gear generator's.
Then it was a matter of cutting all the teeth out.
After that I sat down with some 180 grade sandpaper and shaped them.
There was no major hiccup's along the way but it took a lot of time.
I'm not about to say it's the most perfectly cut sprocket but from a couple of feet away it looks alright.
The one thing I've noticed is that it sits a little flat on the spokes.
So I'll modify it at the back with some spacers to move it a little further away.
The other thing is the version of the sprocket I've been looking at is in two pieces.
So that it can be fitted without taking the wheel out.
I think I'll add that detail!
Hopefully if there's going on with it people wont look at the teeth to much
Cheers
Trev.

You are just going to have to have a go at a wooden geared clock, Trev.

When I was younger (about this time yesterday).
I had it in my head to build a room full of wooden gears and levers.
Even a huge clock in the middle of it all with a giant governor on top of it.
When you opened the door at one end you'd pull a lever that set it all in motion.
About five minutes later at the other end of the room it would flick on a light switch.
I was going to call the hole thing "Progress"
I really am a Luddite
But after trying to make one little sprocket I'll leave the idea for another lifetime.
Cheers mate

I made up some spacers this morning to move the speedo drive away from the spokes.
Mounted on the wheel it looks about right.
The drum brake needs to fit in front of it.
So there'll be some juggling around to be done.
I'll add the detail of the speedo drive being in two halves after the drum has been made.
I also need to get the spacing right on the drive sprocket on the other side.
Still I'm getting closer to be able to strip it all down to be painted.
That's the part I'll really enjoy I've pretty much seen enough of the grey primer.
Cheers
Trev.
