Title: Hello:- Speak&Spell 'Body contact' advise
Post by: cane creek on September 16, 2010, 10:59:09 AM: Hello ,

I'm a total amateur and I’m about to perform my first circuit bend on a Speak & Spell so forgive me if this sounds a silly question, I have a diagram (Ghazala/cantor) on it shows the Pitch dial/Potentiometer is wired to a body contact.

What is the Body contact for ?
Do I need a body contact ?
If needed where can I buy one from on the net (any links) ?

Thank you in advance , as i await eagerly with solder iron in hand ;)

PS this might help

So reading through the threads it would seem any type of conducting metal stud will do the trick.

I'm off to B&Q to see what they have :)

Post by: Bogus Noise on September 17, 2010, 03:03:19 PM: I've always used mirror screws, I think they look great on the surface of a bent instrument!

A fiver is well steep though. You can get 4 for £1.29 from Wilkinsons, and it's possible to solder a wire onto those ones. Also, if you've still got the B & Q receipt, you should be able to get a refund.

Actually, are you trying to solder onto the screw or the cap itself? If the latter, make a bigger hole and solder onto the screw instead.

Also, when buying expensive mirror screws at B&Q, be sure not to get the ones with chrome effect plastic caps... ::)
