Aluminium Profile Type Router - Initial questions

[AndyUK]

Edit - Fuse question. The Transformer will be 750VA - 2 x 65V output. I ordered 10A D curve MCB seen on others diagrams, but I'm thinking 750VA/230V is approx 3A so 10A is very high. Or am I missing something (most likely)

I believe that D curve MCB is sized to cope with the inrush current. A 1KVA transformer will only need approx 4A in steady state on UK mains (varies with min input voltage and efficiency) but the inrush can be something like 100A for a very short amount of time (dimming lights anyone?).

My linear motion parts are finally here! Happy with the service from Fred at BST - all parts received and in good order. Took a fair few extra weeks but with the worldwide situation at the moment not at all surprising!



Looks like most aluminium supplies however are shut so maybe time for more electronics..

So today's question - does anyone know of a coupler for a 10mm end of the ballscrew to a 10mm with 3x16 keyway (on the motor shaft)
I got a load of "oldham" couplers from BST but they are 7mm/10mm bore with no keyway. Stupid question but does the keyway detach?
The problem is the hybrid steppers are not standard 7mm shafts!

Thanks
