No place for a bridge ground?? Rear-route Thinline

[NiceFirmHandshake]

Hi guys, do any of you wizards have any suggestions on how to get a ground wire from the back cavity to somehow make contact with the strings? There's no bloody hole to run a wire to underneath the bridge like you can see in the red ring.
The only thing I can think of, is that I think the bridge pickup's mounting ring will be butted up against the edge of the three saddle bridge, so maybe I could run a wire into the bridge pup route, then into a channel underneath the pickup ring and under the bridge. Anyone have any better ideas? Is there a right way to do this?

With the tele bridge, many folks ground the bridge either by running a wire up through the pickup cavity and clamping it against the body with the bridge plate, or use some copper shielding tape over the lip of the pickup cavity to achieve the same result.

Here's our own Stratamania's version of the solution.  Looks pretty tidy.

Will that get a Tele humbucker bridge? If so, Ian's suggestions are correct. If you are not going to use a Tele bridge, then you may want to drill that little hole yourself with an aircraft drill bit (one of those 12" extention drill bits) down into the control cavity.

Thank you all for your responses! Maybe I should have been a little clearer; the guitar will have a short tele bridge, and humbucker mounting ring exactly like this configuration.https://images.reverb.com/image/upload/s--m4H0evRv--/a_exif,c_limit,e_unsharp_mask:80,f_auto,fl_progressive,g_south,h_620,q_90,w_620/v1490035288/xtm4r3kn7jtge6ovcenu.jpg Although, I think Bagman's pic might still be the solution because as I said I think the pup mounting ring will be butted up against the edge of the bridge plate, so there won't be a gap revealing the copper strip.

The hole connecting the bridge pickup rout and the control cavity rout is large enough for both wires. I've worked on several makes through the decades that just slipped a bit of stranded wire under the bridge for a ground. Heck, on many Jazz basses they use a strip of copper tape or brass out in the open for all to see.

Aircap method is good.

AirCap the issue isn't getting a wire from the control cavity to the bridge pickup route, it's getting it from the bridge pickup route to the bridge, as they are totally independent in this build. Please see the link in my last post to see what I mean.

Ouch, I think you're up against it.  You'll want to get the long, skinny drill bit going at a shallow angle.

I did. My method will work.

 

[bagman67]

Aircap, I agree the strip of copper tape or a wire running from the pickup cavity to the half-bridge will *work* but it's not necessarily the most aesthetically desirable.  I think OP needs to drill a hole if he doesn't want a wire or tape-strip visible.

Right. They're called "aircraft bits", and are typically 8" to 12" long for drilling through hollow bulkheads.

For guitars and such, they allow you to lay down your drill motor at a shallow angle to drill more nearly horizontal holes while still having clearance for the spinning chuck without grinding the hell out of something that shouldn't get that abuse.

Right, I understand my options now - thanks guys. If the pickup ring butts right up against the edge of the bridge then I could discreetly run some copper tape from the pickup cavity to the bridge. If not, and there is a gab that would show the strip of copper, I'll drill myself a very sideways hole. Thanks again guys.
