    Hi all, Is there a supplier in Aussie where I could get.
    #NSS2430 Spur Gear
    #NSS2460A Spur Gear
    Or should I source these from USA ?
    thanks

    If you have the details of those gears you'd be surprised what you can find on ebay these days. Or, depending on the sizes, you could make them.

    I'm not familiar with those part numbers. What are they?

    They are not in America but for Module standard gears world wide I have always found http://www.maedler.de/ to have the greatest range in sizes, types and materials,
    They typically ship the next day and will post or DHL to you anywhere in the world.
    I ordered the timing gears for my radial motor from M├Ądler and had them in three days,
    An added plus is that their catalogue is so easy to read.

    Hopper, They are part numbers from a set of plans from the states (Henry Fords First Engine).
    Apparently they are from Browning, Stock Gears.
    It does list the specs for the above part # so maybe I try elsewhere.
    As suggested by Cogsy making my own is out of my skill level.

    TEA Transmissions in Qld have a wide range of gears, as do Ronson gears (in Victoria i think). Both will ship anywhere in Australia at modest cost. I got spur gears for my project from TEA and found them very good to deal with. If you know the pitch diameter and number of teeth it would not be hard to find a match in their range.

    As long as you've got the means of indexing (rotary table, dividing head, etc.), it really is fairly straightforward to make your cutter and then cut your own gears. Here's the link to all the info you need - http://www.helicron.net/workshop/gearcutting/gear_cutter/ . It's only out of your skill level 'cos you haven't learned how to do it yet...

    Cogsy is right, in that they are not hard to make. But there needs to be skill and knowledge in shaping the tool to provide the approach and departure ramps on your gear tooth.
    Probably 50 years back when I was the apprentice modeller to my "Opa" (Grandfather) we would have made everything ourselves. But now first class gears are available just about everywhere, so I would just buy what I need and use my own time on making the parts that I cannot readily purchase.
    Just my five Pfennig.

    A few Aussies have bought involute gear cutters from CTC tools in Hong Kong. Most have purchased a complete module set. See:
    http://www.ctctools.biz/hss-involute-gear-cutters/

    With the number of Arduino based indexing scripts for rotary tables on this forum, you can't go wrong.

    Hi Rod and Group,
    Yes, I think Australia has a more friendly import scheme than does the EU
    If I purchase something from outside the EU (eg China) and the landed value including postage cost is more than €25,- I then have to pay the government €10 processing fee plus 20% tax on the value of the goods plus the value of the postage,
    And to add insult we do not see the goods until all of that is levied and paid, We get a letter telling us what is what and then we have to pay it, Finally then the Customs office send you the goods. But often they don't trust us so they want us to send them a copy of our bank statement and whatever to prove that we are not understating the value to reduce the amount we need to pay. Which all puts another week or two on the delivery time.

    Is that the engine made from pipe fittings and the like? Looks like a real interesting project and a lot of fun. Just looking at the video's etc online it looks like any two gears with a 2:1 ratio could be used to drive the camshaft. Possible cheap source could be lathe change gears etc. or just whatever you can round up on eBay. Or the cam drive gears out of a four stroke lawnmower engine etc.

    If high strength or heat resistance isn't needed, making those gears from acetal (Delrin, Pom) is pretty simple using the method suggested by Cogsby. (http://www.helicron.net/workshop/gearcutting/gear_cutter/) If the gears aren't perfect the plastic will still let them run well and the gear cutter can be made from any steel you have laying around as it doesn't need heat treating to work.
