Thanks for your compliments!
I have the use of a very broad range of hand files and the surface finish is attributed to a "3m convolute deburring wheel".

Thank you for your compliments, PJs, most kind!
I used one of those curved toothed files, they really raft off aluminium fast, leaving me with plenty of elbow grease for draw filing with the smooth cuts.

Thank you for responding to all my posts and putting up my bits & pieces, Ken!
Could I ask that you credit all my builds to "knoba on https://knoba.wordpress.com", please?
