Very nice work, I'll be your first customer.. I want one

Just an idea but could you make up the thickness with laminations of thinner steel like some transformer chassis's, That way you can find the optimum thickness. Also if it was thin enougth could it then be pressed?

If some one can make the former I'll happilly press you out as many as you need. 10 ton Hydraullic press with foot operated pneumatic pump is very quick.

I relaise the production blade hotrails are much thinner, but remember this is to vibrate the string not pick up the vibratiuons...everything has to be beefed up.
Fair point. dose the tuning not suffer from the pull tho?
