[QUOTE="Drbean, post: 100606, member: 2558"] Hey guys use very thin plywood make 2 round circles and sandwich the coil windings in between then put a bead of silicon around outside and glue to supports on top to hold stem . I used black riser tube for water garden sprinklers for stem it's cheap and very stable flattened two sides with a file and drilled hole . You can get it at burnings in various lengths in plumbing section. I made my coil out of enamel copper wire from Jaycar .3 thickness mono construction. I found it ok on air tests but terrible on any minimized ground. Modified connection and fitted dd coil tech with a sad connector big difference .mate if your tight for dosh look up matchless in detector very easy to make works well on beaches , dd coil not a bad machine at all.Dr [/QUOTE]
