I see you can just replace them... you could also cut them in 2 and use precice spacers between each to get good alignment.
do you have any good link to learn about tolerances & material quality etc... was looking at link below, how to compare with your misumi, and the quality of f.e the UM2 shafts ?

Possible... I would still just make new brackets if I needed a different length - KISS
I don't have any references for mechanical tolerances & quality. When you're able to buy stuff from Misumi, you have two major advantages:
1. You get the best quality there is
2. Lots of information in their catalogue, like "use these kinds of shafts with these bearings". Also, you can generate STEP files for the parts and their mechanical drawings are very well readable.
So, I basicaly don't have to worry about these things anymore
I might consider having an adjustable stop on one bracket and, so that you have a way of fine tuning them to be a perfect 90 degrees.
No go - the profiles are what makes up the rigidity of the machine. It is absolutely critical that they form a rock solid entitiy. I will measure the angles when I receive the parts (5 days left..).
I suppose that "+-0.5mm" length tolerance refers mainly to "how well they dial their cutting machine". Meaning when they cut several parts of equal length, these parts can be +-0.5mm in respect to the specified length. But less than +-0.5mm difference between the parts.
If that's true, then the error in my frame becomes even smaller.

Grrr. Fedex says my parts from Misumi were delivered today, but they clearly were not (wife was home all day and says there were no deliveries. Also, no one at FedEx is answering the phone.
Update: Driver says it was delivered to the wrong house. Will be here by 8 pm tonight.
