precision wire bender

Hi: I'm thinking about either purchasing or making a precision wire bender. The nominal diameter of the wire won't be over 3/8". However, the precision must be accurate to within 5 degrees of the spec'd radius either way. If the call-out is 200 degrees radius it has to be within 190-210 Anyone know ...

Is there a web reference or something that'll show me how to grind a good HSS facing tool? I'm not opposed to doing it, but you rightly assume that I don't know how to.
Let Vance show you. He's the best instructor I've found so far.

Such advice is why I ask and so, pay attention to the responses. If I understand the majority of the comments the way to go is quality collets and a power draw bar.
Who purveys quality collets?

Thanks for your support.

Thanks for the insight. I like the power drawbar idea!

I am concerned that an endmill held in an R8 collet is not as secure as one that uses a set screw.

Is there an R8 shank holder that will use a set screw?

thanks

Quick change tool system for Bridgeport J2 series 1 2hp knee

HI: What kind of quick change tool set should I buy for my BP mill?

Royal is too much money.

Anyone have experience with Tormach's QC sytem?

The spindle has a R8 taper/drawbar.

Thanks

Hi Bill:

Great signature line. I ended up being a farmer with a tractor that wanted to make implements.

As far as getting loaded goes that is a sobering suggestion.

:P

Thanks for the input,
