Great effort!

I cant really add much to what the others have said other than I use different sizes of nails for my flush setting burnishers.

I cut the head off, cut to length, form the end to a point then round it over. Highly polish it of course, then set it in a small mushroom shaped handle.

Control of the burnisher is also extremely important to avoid slippage and scratches, so I brace the tool with the spare hand to prevent unwanted movement.

One other thing that I find to be VERY important when flush setting, is to make sure the metal is properly annealed beforehand. Once its workhardened, then the job becomes much harder.

Cheers,

Nick
