Aluminium Profile Type Router - Initial questions

[CNCRY]

On the model, you show BOTH ends of the ball screws using BK bearings which are the fixed end bearings, which is the best way to fasten, BUT it's not the standard way. Usually, you have a fixed end BK bearing and a floating end BF bearing, so if you want BK on both ends you will need to tell Fred at BST otherwise they will machine them to standard.

Also mention you want the "F" Dimension which is the coupler portion at 25mm otherwise they will machine it 15mm.

Tell Fred you want the best BK/BF bearings not the cheap ones.

Thanks Jazz - the BK bearings in the image were more just to guide placement and I'd just been copying the same object in fusion 360 rather then using the BF, but I do intend to do it the standard way.
OK - will request a bearing upgrade too. As mentioned in another thread, no idea if BST are shipping out at the moment, so will check on that. Just being impatient to start building something:)
Does the design overall look OK? It's heavily copied of course with a few tweaks!
I do intend to take up your kind phone offer soon - I think electronics will be a Major learning curve so have many questions!
