Re: [PSUBS-MAILIST] A question for those that have/are building their own subs...



Dear John

Today I use : 

A bigger hand drill press with torque control, (all 4 days)
a medium hand drill press with torque control, (all 2 days)
a small battery power hand drill press with torque control, (8 times
each day) 
a slow motion bench drilling machine (for stainless steel), (2 times
each day) 
a electronic hand help electro compass saw,     (2 times each day)
a electric welding machine for electrodes,      (2 times each day) 
a inert gas arc welding gear, 		        (1 time each day )	
a PC with CAD programm and printer	        (in the evening  ) 	
and a hand steel cutting grinding tool.         (10 times each day) 

Thats all - no mill and no lathe. 
For parts which needs a mill or a lathe I ask one of 
the metal shops around here to build them. 

During the Sgt.Peppers building time I have used : 

A medium hand drill press without torque control,
a hand help electro compass saw,
a electric welding machine for electrodes, 
and the hand steel cutting grinding tool.

And don't buy the tools with the lowest price..
and not in the supermarket - and not a hand steel cutting grinding tool
with a plastic head - maybe ask a professional worker which 
tool companys he likes. 
Good firms for electro tools (in europe) : Metabo, Makita, 
but most of my tools from Bosch (which is a good balance between quality
and price)
