|  1-2-3 blocks?
I've been seeing these little dudes in various places and never could figure out what exactly they were for. I know that they are exactly 1"x2"x3" and perfectly square, but thats about it. Oh, and there's a bunch of holes in them too. What exactly do you do with them? Not the generic short answer please...I'm looking for "I'm going to do (blank) so I grab the 1-2-3 block and put it (blank) to (blank) the (blank) before I (blank) to ensure that the (blank) is (blank)." or something similar. Someone please enlighten me.  |

They are used for clamping or setting up material in machines. I've used something similar on my perforated welding table. You can attach them to a table with a bolt or a special 'clicker'. |

In our shop, we use them all the time for a couple of different purposes. Firstly, is to square something to a machining table. Say you lay a large piece of plate aluminum on the table, and want to mill the edges so they are all square. You'd start by finding the side that is 'most square'. Then lay your plate up on the table, while holding a 123 block against the back edge of the milling table. Then press your alum plate up against it till it is flush. This way you are as square as you can get (without breaking out major instrumentation) so you waste the least amount of material. Another purpose for them is for setting up to indicate (measure) something. Say you have a part that is 5/16" in diameter, by 3.xxx" long, and you want to know the exact length. You can take 2 of the 123 blocks and place them in an "L" shape (this is if you don't have a Vblock handy). Stick your material in the corner of where the two 123 blocks meet, and hold it all flush. This way you know your material is as close to square to the measuring surface as you can get it. Other uses are mainly for setting up holding fixtures, holding something at a height you know to be exact, quick checks for squareness, etc.. There's a lot of uses for them, limited only by your imagination I would say. |

So its like an all purpose quick-check/square/height type thing. I take it the holes are for pinning/bolting it down if its going to be used repeatedly?

I've been wondering the same thing. They could be handy as a surface for indicating when the mill table starts getting scratched up, but right now, I can't think of what else I would use 1 for (my machines are metric, I'm usually not worried about high level of accuracy for RC parts, and I would need to pay big money for shipping where I'm at).

Unless you need it to be metric too, then you're boned.  | |

Before I got a set, I wondered the same things.......what the Hell are they good for. Now I can't imagine being without them. I use them for everything from setup, to fixtures, to measurement. I use them on the knee mill as well as the machining center.......indispensable little gadgets Gauge pins also rule. |

We use them for help with inspection of parts. The reason they are called 1,2,3 blocks is they are 1.00 thick and 2.00 wide and 3.00 long. Sometimes we will use them on a hand mill to help with a set up but for the most part we use them on a surface plate to help with inspection setting parts on them or against them. They are handy. A must have in any shop, But remember you get what you pay for.

We use 1-2-3 and 2-4-6 blocks for all kinds of things in our shop.Most come with threaded holes and clearance holes so you can bolt something to them and then bolt them to a fixture or the table of the machine.I also found them usefull for crawler stands.  |
