How to assemble shaft to coil unit on home-made detector?

[Anonymous]

Hello,
I bought and made the Golpic3 PI detector which works great, but I have problems with the mechanical assembly. As lower stem shoud be no-metal, I can't imagine how to make the link between a fiber-glass shaft and the coil box. I have the plastic screws, but I don't know how to do the link with the rod. Could anybody help ?
Thanks

Hi Marc,
I made a upper stem up from copper tubing and a tee and foam covered tube handle for the handgrip. The fibreglass bottem stem was a perfect fit.
The copper is heavier than aluminium but more weight actually helps counteract the weight of the coil.
The above was to hipmount a Whites Eagle Spectrum which is what Id do with the Goldpic as it looks even bigger than the Spectrum.
The copper tube could be bolted to the control box with a slot for cable entry and all entry points sealed.
I have a Goldpic kit but have not made it up yet.
Its a pity we are not neighbours as Id make the handle kit for you and you could assemble the Goldpic kit for me. Only joking.

Hi again Marc,
I keep getting disconnected so my posts are disconnected.
The lower stem can be fitted with a wooden dowel to prevent crushing. The coil can be fitted with thick plastic angle brackets bolted or glued. The lower stem and coil brackets are drilled for the 1/4 plastic nut and bolt assembly.

Hi John,
Thank you. Your advice is helpfull. I don't have many skills with plastic mechanical assemblies. I see no many people made the Golpic. Also I see no stories of field experience with it on this forum.
