Check with @fordf150 Nate

Thanks, but I am not going to bother Nate with a single sprocket.
I am certain he is covered in work without my inquiries.
He is a great guy, I've had dealings with him.

I'll figure something out, or just ditch the idea altogether.

I think it's just a picco rim sprocket filed to fit?

 

[Woodpecker]

I think @Homelite410 mills them.

 

[Dub11]

I forgot about these guys too.

It's a little more than Filed out....that stuff is hard!

Bored out in the lathe?

No sir, I use a 1/4" carbide end mill on the vertical mill and circular interpolate the bore then mill the splined deeper with a 3/32 carbide end mill. Process takes 7 minutes and I get 3-4 sprockets per set of endmills.

How much are You selling those sprockets for?
What do You have, 7 tooth, 8 tooth?
I'd be interested in acquiring at least one.

Yeah, quality sprockets are hard.
Even solid carbide will give up chewing on them.

Those have got to be damn hard to eat up carbide like that

And here I thought they were just some cheap powder metal junk.

Carbide tends to shatter.
It doesn't take much to damage the flutes of an end mill bit.

It wears off the edge on this material but yes it shatters. Let me look tonight and see if I have any rims left.

How does an hss end mill do? Can you do one sprocket?

HSS/HSS-Co can not be compared to Solid Carbide given identical harsh conditions!

HSS is less shatter prone than Solid Carbide, but it is also much softer and "bends" easily under side feed pressure.
HSS gets dull fast processing hard metals and soon breaks as a consequence of the dulling.
A rim sprocket is made of cast steel, an HSS end mill would fail miserably trying to process one.

Solid Carbide can easily process HSS, even HSS-Co (Cobalt alloy) - given that cooling is secured and the feed is not set too aggressive.

I should have some dull HSS end mills somewhere, maybe even remnants of shattered/chipped Solid Carbide end mills - if I find any I'll post pictures.

I am sold to Solid Carbide, I just love the stuff.

The above is just my observation, opinion and preference!
I do not mill on a daily basis and my knowledge regarding milling is rudimentary at best.
Although, I do know a little bit about drilling (no pun intended).

Thanks, much appreciated!

If You were referring to Solid Carbide, there are cheap ones that work but don't hold up well under normal conditions, lest under harsh ones.

Quality Solid Carbide tooling on the other hand is worth the investment and will hold up extremely long under normal work load.

Again, just my humble opinion.

P.S./Edit:
To make this post "on topic", I am about to upload my first batch of Dolmar PS-550 videos to YouTube.
Stay tuned.

I was talking about the rim sprockets. For his little they cost I figured they wouldn't be so tough.

They are tough indeed!
Imagine the amount of power they transfer by the time they get replaced.
