I have one source for getting extruded gear stock: http://www.greenbaymfgco.com/index.php. I believe if was Forrest Addy that recommended this source – Thank You.

However, I would feel more comfortable if I had another source or two for steel or aluminum gear stock but, I have yet to find any more sources.

Does anybody know of other suppliers?

Thanks,

plm

Extrude, I am not sure about. However I do have a "stick" of pinion stock that came from Boston Gear.

I did not buy it from them, I got it in a "mixed lot" of metal stock. But, evidently they have it.

Don't forget SPC / Sterling Instrument / Stock Drive Products in New Jersey I think. Don't know about nylon, though.

Dr. Rob,

Your right, SDP is a great place to get motion components – they are who I use in my prototyping stages.

I am tweaking my design and what I was looking for were long rods of gear stock that I could cut to my own length and put my own hubs, face widths, bore etc. in. Basically, have the DP, teeth, etc. taken care of and be able to customize the rest.


Snowman,

Boomer is right, if you are looking for finished gears in nylon, SDP is a great place to get them with they have good service. Sorry for not being more specific in my original post.

Great. Wish only I could help you with one other thing... deburring gears after being turned / faced to width on lathe.

Every tooth gets a burr on the back side of the tooth when you cut them. Sometimes a wirebrush will do it, but also at the expense of the tooth profile at the corners of the gear. Sanding or grinding sometimes does the trick too, with due care.

Anyone know if you can still get pinion rod in "cycloidal" tooth form for making clock pinions.
I know that it was available in un-finished form many years ago,and had to be filed to shape by hand. Which rather defeats the object to me.

No, Phil, I don't know that. I do know however that I still have a couple-three cycloidal hobs if you're interested in a trade. Think I still have your hob list too.

Hi Dr Rob

Long time no speak.
I think most if not all my duplicate hobs have already gone, but what do you have spare as I might be interested if they are sizes I can use for musical box work.
