WEN 10423 3 x 2 x 1-Inch Steel-Hardened Precision 123 Blocks, Two Pack

I LOVE these. I watched a video on making a cardboard dollhouse and she mentioned these. I never heard of them but looked them up and ordered a set. (LOVE Amazon too) I started my own dollhouse (which I just finished the other day) and used the blocks a million times. They are small but heavy, compact and with straight edges.

I like the Value for money and the clean finish

So flexible, can use it to set up any fixture or tool. Cant imagine not having a set.

These 123 blocks are cheaply made and not suitable for more precise work.

Accuracy is good from my measurement. Falls within spec. Great value for what they are

Al primer viaje, solamente con el manejo de la maleta en el aeropuerto, el arco llego doblado, lo que hace que muy difícil volverlo a cerrar y complicado para abrir

Great little set of 1 2 3 blocks for the price. Measured within about a thou on length, width, and height. They were out of square by roughly 2 thousandths. The blocks were not machined as a set, so they varied slightly.

I have not checked the accuracy with a mic, but they will work for me

They are one two three blocks. If you dont know what 123 blocks are you shouldnt be reading this review. These are perfectly acceptable 123 blocks. By my calipers they measure exactly an inch, also two inches, as well as three inches. I used them for welding setups and the stood my material off by a precise inch. I have also used them to measure variance in a lathe bed and they worked perfectly. Buy these 123 blocks. They are an inch, and two, and three.

Theyre amazing for making simple mill table setups. I recommend them highly for the hobby shop.
