    Hi I had KJN cut and drill my frame (With counterboring) which is a little cheaper than using the corners but also stronger. They will do it to your cad model, you could still use corners as well for extra strength.

    Cost me £35 +vat for 18 holes with counterboring.

    I already had the corners I did it for strength, I used m12 50mm A2 socket bolts.

    A top tip if you do what I did make sure you get some corners then use them to get the extrusion straight before putting the bolt in when it's tight you can remove the corner and reuse.

    Also 9045 extrusion takes M12!!!
