All- I need a 13t .5 mod (I think 20 deg PA) and a 52t .5 mod gear. 5mm thick or thicker would be fine.
I'd prefer to not make them if possible.
I only need one each. Any help?

Have you tried emailing the gear manufacturers asking about the gears your looking for? Most the time they don't have all the gears they make or can make on their web sites and you have to call or email them.

found some close but not exact at http://www.qtcgears.com/Q410alph.htm
from what I saw, the stock tooth counts skip around a bit with some fairly large gaps...

Oh, you may have to specify material (I found only plastic gears close but there was steel shaft to work with that module etc.)

If you are stuck, I can make them here in the UK in plastic or steel. Pm me if there is anything I can do.

What does ".5 mod" mean? I thought gears were sized by number of teeth,
diametral pitch, and pressure angle.

When I need to buy gears I find them at MSC Industrial or the Boston Gear catalog.

John- That company seems to have what I'm looking for.
Wouldn't be the end of the world if I had to get them shipped over.
The price is fine.
Just seems like I should be able to find something here in the states!

Any others state side?

Thanks- Sid

I will assume you glossed over my post. Have you tried Boston Gear? Have you done an internet search? I suspect not. It's your gear and I expect you should look it up. Gear makers are not that hard to find, it just takes a little searching on your part.

I assumed you read my post.
I need one gear each.
Boston gear doesn't even make metric gears.
I came here AFTER an internet search.
Thats what this board is for, HELP. (mostly)
If you have none to offer..........
I thanked the person who did offer help.

This is not my first rodeo.

SDP Aka Stock Drive Products. SAE and metric gearing down to clock wheel sizes. It appears they have 0.5 module gears....https://sdp-si.com/eStore/Direct.asp?GroupID=591

No idea of stock, country of origin, pricing, no connection, blah, blah, blah.

P.S. their website gives the appearance of US based manufacturing, http://www.sdp-si.com/web/html/direct.htm. Where is Hyde Park in NewYork? Is it really an industrial area? No clue...

Camdigger- I looked that site over. They didn't have what I needed either.
I've found the 13t one at some RC Heli sites but that 52t is an odd ball.
Looks like I'm going to have to order from the UK.
Wonder what shipping is on a 1oz gear? HaHa.

Sid,

SDP has 13 and 52 tooth gears in plastic but they seem to be only 3mm thick.

Other than that, can you use a different combination that gives you the same ratio say 12/48 or 15/60?

There is simply no way I could make ONE at a better price than that. Key riced. I can't even fire up the machines for that. :)

Economies of scale at work.:D Costs $100 / unit for one; $200 per 100 units; $300 for 500 units,, etc ad nauseum...


Seriously, Sid try their 1-800 line. http://www.sdp-si.com/web/html/capabilities.htm They may have a customer rep with enough smarts to steer you to a solution or even offer your a price on a custom made gear.
