Earthing a two humbucker kit

Quote from adam on November 12, 2012, 14:01
Dmac the guitar kits went to Melbourne by mistake. We now expect to have them around 29 November. It was a mistake at the Port.

OK, Adam, I was thinking that if you needed to get a bit to get the kits out and had trouble finding a bit, I'm sure I could find one lying around the secret bunker that I could have Express-Posted across to get the kits moving.

The offer stands. Let me know if it's possibly needed as the current job is a Kramer fixer-upper and I won't need it for a little while.

Melbourne, huh... Quality service!

So what you guys are saying is that It would be advisable to pull apart my Lp and insert a earth wire from the bridge to the bridge tone pot.

Hi Nick, I was hoping you would catch this thread. I think from a safety aspect, I would recommend running another earth wire from the bridge tone pot to the closest bridge post. This just requires drilling a hole from the control cavity to that bridge post hole. To do this you will need an extra long bit. Dmac suggests a 3 mil bit, but I would go a bit thicker. These are pretty inexpensive. Then just leave the bare wire so it's contacting with the bridge post when you put the bridge post back in.

I'm going to do up a video instruction for this, so if you want to wait for that I should have it online in a few days.

Sorry for the inconvenience. Fortunately we got this before we sold too many of these kits, so only a few people will need to be contacted.

That wont be a problem, I might get some copper adhesive at the same time and do it all at once. I dont know why I didn't think of this myself.

Yep, I earthed my LP by drilling a hole from the post hole into the cavity.
I was surprised that this was not pre drilled, but it was no problem for me to do it.

Problem solved!

Good to hear DB, one less person I need to contact and explain our stuff up. I do wonder how many customers actually follow the video instructions. I take it you didn't need to refer to them DB?

For the record, what sort of bit did you use dingobass? Any problem making the distance from the control cavity to the bridge post? Also, did you actually solder the earth to the bridge post or just have it at resting contact?

Hey dmac, I responded to this earlier from my phone but it doesn't seem to have registered. Thanks for the offer, but I'll go and buy the appropriate bit so we can fix the remaining stock and any that arrive with a grounding hole drilled.

I'll also contact the factory and ask them to pre-drill the necessary hole.

Hi Adam,

I did watch the vids, but it was some weeks before I built the LP.

I actually thought at the time that it was part of the build that was left up to the individual builder, which I did think at the time was a bit different but there you go...

Having built Basses I automatically earthed the bridge without too much thought.

I dug out my extra long 4 mm drill bit and bored that hole

I just relied on the contact of post on wire and as the fit is tight, it worked OK.
Checked it with the multi meter just to make sure.

And that's all that needs doing. I normally strip 1-1,5cm of insulation off ad give it a light twirl. If I feel particularly energetic I might tin the wire with a bit of solder, but not solder it to the post.

I position the wire so that its entry point into mounting hole is roughly where the insulation ends.

A Facebook question from our friend Nadiene in Ocean Grove (remember the cool, swirly LP-1?)

"Nadiene Dini: Any hints if the bridge posts have already been hammered in????"

I've actually pulled out my bridge posts, using the back of a claw hammer (and cardboard to protect the body), but it's not something I'd recommend, especially given Nadiene's kit's excellent finish.

Any other suggestions for earthing the LP-1 which has been fully assembled?
