Today was the big day : the package for the Contrapteur angle arrived !
Ok so end of the suspense, to summarize : it's good, it works ! ( but it's not perfect ).
All dimensions are good, except for the centering of the holes, that is a very very small bit off ( 0.2mm or maybe less in the direction of the inside … ) but when using the angles, it works ( maybe the fact that the bolts are not exactly 5mm helps ).
The angles are a bit "dirty", but they look super good once cleaned with water and soap.
Also, they are deburred only on one side, but the other one is clean so that's ok.
They weight less than the contraptor angles obviously, that feels better when building, but it's subjective.
The small problem with centering scared me a bit so I decided to try it and build something with it, you should recognize it :) :
I didn't have the exact angle length for the present plans of the contrapteur mini-cnc, so I used lengths that were close …
The screws are the shorter they had at the hardware store ( 15mm ), it needs even shorter screws ( 8mm would be good ).
The machine feels very stiff, and the fact that the screws all fit perfectly makes building it very very easy : everything just stays wherever you put it :)
Small problem : due to the light weight , lack of control when using a big electric screwdriver sent the machine flying to the other side of the room, hurt my arm a lot … will be more cautious next time.
When ordering more, I'll have to ask for the holes to be better centered … maybe define a set of tests/shapes for the angles to be sure before shipping.
With the holes better centered, it would really be perfect.
That's all for today !
Super happy !
