Salad drill

[whiskywill]

I had never heard of these before I needed one.

I have the 6 x 10 version but need a 6 x 8 drill. Does anybody know of any other source for this type of bit?

lettuce see...

it does say if you want other sizes, to contact them.

could you replace the drill inside the bush with one the same size- even if you needed to have a sleeve made. Is it a single job, or a regular requirement.

I understand that to mean if you need more than one size. Rather than ordering individually, you add a note to tell them the selection you want. This message appears further down the page. "If you want other size, please leave a message to us in your order.
(like : i want 5293--2 pcs, 5305-- 3 pcs) "

This is for the tuners and bushes of a ukulele. I might make another in the future, but then again, I might not.

Use a brad point wood drill of the larger size.
Drill down the depth you need the large hole to be.
use the small size brad point drill to pick up on the larger drill's point inside the hole and drill through.

Not as much fun as a gadget, but it works.

Thanks but a bit sloppy. I tried what Sunnybob suggested in a piece of scrap with a reasonable result but the bush was slightly loose in the 8mm hole so 8.6mm is definitely too loose.

seems like a wonderful time to learn how to grind a custom drill bit.
whats the web thickness on am 8mm drill bit? I'd need to look but I wonder if you could grind an 8mm bit to have a 3mm leader, you could also thin the 8mm to the required press fit.

I'm wondering if the bushes are 5/16'' - just a tad under 8mm?

I ground this last night (and tested it, hence the hole and the mess) from an old bit that needed sharpening anyway (and has welding spatter on it for some reason), please ignore the gawling on the shank, it's what happens when you lend tools to people.

worked great.
chuck the bit in a drill, spin it against bench grinder, cool, grinder, cool, grinder, cool, measure. think this is 5.5x8 as I was in a bit of a rush and didn't take my time.

This would work more accurately with the workpiece fixed down on a drill press - you'd be guaranteed the same centres.

I've had a couple of those for donkeys years Whiskywill, bought as part of a job lot but never knew they were salad drills?

That is exactly how I did it but my drill didn't have enough travel to be able to change bits without moving the workpiece. It didn't occur to me at the time that the depth stop might be in the way. I will check this evening.

I would try that if I could get back the bench grinder that my son borrowed off me two months after he gave it to me as a Christmas present. That was about three years ago.

You might be right. They measured 7.9mm with a quick check with my micrometer but that may be because they are ribbed and I hit a groove not the peaks of the ribs. Also, the tuner post itself measured exactly 6mm so a mixture of imperial and metric is unlikely but not impossible. They came from China.

You have an unusual set of Chinese uke pegs. The 20+ sets I've bought over the last few years are all 5mm shafts.

I use the big drill/little drill method, eyeballing my eggbeater drill against a square placed upright on the peghead. Rather than trying to find the exact size drill for the bushing I just drill 7mm and then ream the hole until the bushing fits. It's a uke dammit! Precision in fret placement yes, but it'll still play if the rest is entirely asymmetric

If yours are friction tuners and all plastic except for shaft and bushing, you can make them work far better by adding a crinkle washer between the knob and the plastic tuner body. Also, remove any edges on the plastic casting of knob and base where they meet.

Pm me your address. If it'll fit in a normal envelope you can have this one.
