This is a warning
If you install a dowel pin, be careful witch one you use, because I got the surprise when I made my 2D to realise than the 1/4 dia dowel are at .2465
After investigation Missler return to us a picture of the standard they have used, they have follow the US Standard UNHARDENED (.2465)
This pin was comming from THEIR librairy, and if I use the dowel from DME inch or PCS Inch the dowel are at .2500
Why they have this different it's because they just took the first standard they found and they didn't compare with what it was done inside the mold modul.
The reel true is yes it exist a different beetween HARDENED (.2502) and UNHARDENED (.2465) and they have decide to put on their librairy unhardened.
Is the first time in 28 years experience in mold making I ear than a 1/4 dowel is smaller, I ask also the staff of the tool shop and is same thing from them.
I would like to have your feed back about what do you use the most often HARDENED or UNHARDENED. To me allI have use in 28 years is hardened because when I want a 1/4 dowel I want .2500 and you guys?
