Re: Wiring diagram sanity check

If they're cheap Chinese pickups, you can probably pop the ceramic magnets off the back easily, flip them over, and wire them backwards for RWRP. Simple and worth doing. Of course that would only give you humbucking in 3 of the total possible 15 combinations. I'd also suggest using higher value pots...

Re: Wiring diagram sanity check

Those blue wires are a bit too dark to make out properly, but if I'm interpreting the diagram correctly, it'll work fine.

Re: Spinning a radius dish

You can use a router to form the v-groove. Remember that V-groove belts do not bear on the bottom of the channel, only on the sides. If you do not have the appropriate straight tapered router bit, you can use a small diameter straight bit and angle the router. You can flip the disk rather than re-ji...

Re: Spinning a radius dish

Hi David. You'll need to use some sort of bearings to support the outer edges of the dish. You could use "Lazy Susan" bearings, or a series of castor/universal bearings around the perimeter. In order to get the speed correct, you could use a belt and pulley system, with the outer perimeter of the di...

Re: anyone know what this is?

A lot of guitars with that headstock and string retainer were branded as "Saturn", but as to who the OEM was (it was a re-brand), that's up for speculation.
I've also seen similar ones labeled Silvertone, Guyatone, Tulip, Kay... the list goes on.

Re: anyone know what this is?

I would guess Teisco, could also be early Ibanez, but there were all sorts of different un-branded guitars coming out of Japan in the 60's and 70's, a lot from the same factory's under different labels. I've worked on some very similar un-branded guitars. They can be a pain to get setup nicely, but ...

Re: Wiring issue

Hi Paul.
Position 3 adds a high-pass filter (the cap) to the bridge, giving a bass cut. This will sound similar to out-of-phase tones. Sounds like everything is working as it should.

Re: Greg Robinson's Lap Steel

Thanks Ron! Good luck with your lap steel build too, I'll be interested to see once you get started. Regarding tuning, well, I've never played lap steel before, so I'm not really sure. From my reading though, it sounds like C6 is probably the most common of the tunings, at least for Hawaiian and wes...

Re: Greg Robinson's Lap Steel

Hi Jason, yes, I'm using "real" ferrules. They only end up costing about the same as you got yours (I have wholesale accounts with most suppliers as I run a repair business). I also have them in stock for repairs. Easier than finding a work-around, for me at least. But I respect your motivation to u...

Re: Experimental rail pickup construction: wiring question

Yep, it's as I suspected, somewhere your starts are connected together, either in the pickup itself, or in the lead - black and green, so the two coils are in parallel. If you were to bypass the switch and use either black or green as one lead, and red/white as the other, you'd get output (but not h...

Re: Experimental rail pickup construction: wiring question

No problem Jason. Given that you're reading 2.4k on each coil rather than the expected 4.8k, I'm guessing that the two coils are in parallel. You may have wired it incorrectly from the get-go (easy to do), or it's possible that there's a short somewhere in the cable, it's easy to melt the insulation...

Re: Experimental rail pickup construction: wiring question

That all looks good to me Jason, and you've got opposite coil cuts for the two pickups so middle position with both humbuckers cut should still be hum-cancelling. It sounds like you've inadvertently wired the neck pickup in parallel, then when you connect it up to the mini switch, either position wi...

Re: Greg Robinson's Lap Steel

I've drilled the holes for the bridge mounting screws and the string-through holes on the drill press. Through holes.jpg And just eye-balled the holes for the ferrules with a twist drill. They're not perfectly spaced, but this is for me, so I'm not fussed. Too much bother to jig up for this, althoug...

Re: Greg Robinson's Lap Steel

Thanks Jason. You're right, Queensland maple (Flindersia brayleyana) is nothing like the Acer's. If I can think of anything that it resembles that is more commonly used internationally, perhaps African Mahogany (Khaya) might be most similar. It's quite stable, machines beautifully, and often display...
