If you are looking for suppliers for parts or material, here are some possibilities.

Unless specifically noted, listings here should not be taken as endorsements or recommendations. They are just suggestions.

If you have information about any of these topics, please get in touch so that it can be shared here.


Parts

General

  • Gizmo's Zone are in Hong Kong and can supply a wide range of mechanical parts to anywhere in the world. Mostly, they are likely to be useful for a range of fixed-size spur and pinion gears in a variety of pitches. They do also have some interesting looking small planetary gearmotors that are not the usual Pololu-style N20 items.


Gears

  • KKPMO Gears can make a wide variety of micro pinions and gears down to 0.1mod. You can almost certainly find the exact gear you need here.


Materials

Plastics

  • The Plastic Shop can supply a good variety of engineering plastics. Although they are an industrial supplier, they can sell you small amounts. For example sheet materials can be purchased in sizes down to 20mm x 20mm if you really want. Rod stock is sold in 3000mm lengths but they will cut that into 10 pieces for you at no additional charge.

Machining

Speeds and Feeds

  • CNCCOOKBOOK Speeds and Feeds has a PDF file with a bunch of useful information about speeds and feeds if you are machining your own parts. Intended for CNC machining, the data is still applicable to manual machining so long as you remember that manual, one-off machining is often a much more gentle process that is less focussed on efficient removal of material. The CNCCookbook site has a lot of other useful information as well.


Electronics

Suppliers

  • Octopart, while not a supplier, should probably be your go-to site when searching for a part. Enter the part number and Octopart will find all matching parts with links to suppliers and datasheets. Invaluable for reverse engineering robots from photos or schematics. Also a good way to track down parts that your favourite supplier does not stock. Be aware that some of the suppliers listed will be distributors like Arrow. However, RS, Farnell, Mouser and Digi-Key will all appear in the list if they stock the part.
  • Farnell Are a premium supplier of electronic components, tools and instruments. They operate world-wide, have a very wide range of stock and are not outrageous for prices - usually. Shipping is fast and reliable. Personal orders are welcome. Parametric parts search can be very useful. The links is to the UK site but they have country-specific sites for lots of places around the world. Note that some items may be listed as US stock. They will be much more expensive and slow to arrive.
  • RS is a long-established supplier of all things electronic. They accept personal orders and have fast shipping which is free for orders made online - no minimum value. Like Farnell, they have country specific sites around the world.
  • Digi-Key boast the world's largest selection of electronic components and they can probably sell you anything that you need. While they are a US based company, they have country-specific sites. Shipping is fast and you can arrange to pre-pay any import duties and tax. Shipping is free for orders over £33.
  • Mouser is another US-based supplier with a UK site. They also serve many other countries. They are worth a look because all the suppliers have slightly different inventories.
  • Rapid Electronics are based in the UK. Traditionally, they have had a more limited range of items but they are often very competitively priced. Shipping is free for orders over £30.
