Could you please be a little bit more specific on what you want to know so that we could answer your question well? For now I'll outline a little bit of what we use. Currently we are ordering all kinds of tools, bolts, nuts, rivets, raw materials, sprockets, bearings, etc. Basically everything we know that we will use. In tools we are ordering new riveters, strippers, crimpers, retaining ring tools, and allen keys(we are trying to replace all the bad harbor freight tools we currently have). For raw materials we are ordering 2x1 aluminum extrusion(both 1/8 wall and 1/16: we mainly use 2x1 to build our robots), and both 1/2 and 3/8 hex bar for shafts. We are ordering AM #25 aluminum sprockets to match. We do manufacture parts in house. We are trying very hard to get a lathe in house so that we can make all our shafts ourselves in addition to a mill. For bolt sizes we mainly use 10-32, but also sometimes use 8-32, 6-32, and 4-40. The most common bearings we use are FR8ZZ and FR6ZZ, but we could use others.
