First time build - Steel Frame CNC Router

[Clive S]

Clive - Thanks for the advice and the heads up. I have updated the original post (#36) to show the 30mm length, will just send a copy of this to Fred Lee when ordering. One thing I am not too sure about is, do they cut this from longer material stock and give you an "extra" Xmm on top of the standard amount or do they just machine back the 30mm and as a result, reduce the original screw length?

Also, any advise on if you normally specify the accuracy and dust protection after the carriage ref ie, HGH20HA ZA C SS ?

I don't think you are understanding this. I see that you have altered the F length to 30mm but you have not altered the overall length.

The overall length = the end for the BF bearing then the screw part then the BK bearing including the threads and the F length So L = the total length .


Ask Fred for the quotation and he will get back to you very quickly usually within about 36 hours.

Edit I think you did alter the length but check
