Buying steel #25 sprockets

[AdamHeard]

I'm looking for steel, flat, #25 pitch sprockets in 48 and 70/72 tooth.

Mcmaster only has these with hubs. I need them to be flat so because they will be welded onto a tube. We can buy the hubed ones and machine them off, rebore them and try to find a way to weld the hardened steel, but I would rather just buy the right thing in the first place...

so... where should I look?

SDP-SI has them in carbon steel.

That's http://www.sdp-si.com just in case Google is suffering from amnesia.
