Affordable tool for sanding guitar saddle?

Post by Thomas » Wed Dec 19, 2018 1:00 pm

I know I can use file etc but it is tricky to do a good and perfect job
I found tools like this

Affordable but has any body used it ? Is it a long lasting good tool?

I would say that this type is a better, more robust and longer lasting design:

They can be found on the bay for a reasonable price.

Thanks that tool is for those who have so many guitars and they make money ... 150 or 180 is a crazy price for some body who might once or twice in years work on a saddle :)

Check the bay and look for the model with brass fittings...it can be had for ~$80.

For occasional use, a piece of sandpaper stuck to a sheet of glass is all you need. Mark the saddle with a sharp pencil, go slowly and carefully and you don’t need a guide.

With shipping and import fees will be more than 100 . I will handle it manually for now until I start a guitar business :)

I hold a block of wood in one hand to help keep the bone vertical and move the bone back and forth with the other hand. Cost ... whatever a piece of waste wood from my bin costs. :-)

I do the coarse work with a block plane first.

With a properly set up and sharp block plane you should not need to sand the bottom of the saddle. I've found that the Stanley #60-1/2 P low angle block plane will cut bone reasonably well for a while if the iron is sharpened to a short bevel. Harder irons, such as Hock, tend to chi p on the hard bone. I use my plane to 'shoot' the bottom surface of the saddle. Lay the saddle down on something like a piece of plywood, that is uniform in thickness and holds the bone up off the bench top. A stop on the bench or plywood helps to hold it in place. Have the lower surface of the saddle overhang the plywood. Lay the plane down on the bench take light cuts off the bone. With a well set up plane you can take a nice shaving all the way along, leaving the bottom of the saddle both square and flat. You could use the same technique, of course, using a piece of sandpaper glued to a squared off block of wood instead of the plane, but the plane works better.

I use a fret file for shaping the top of the saddle, finishing the surface with increasingly fine wet/dry papers. It is a bit like doing one's nails.

I also find this method useful for sanding down my knuckles. Am I the only klutz here?

Probably not. However, by experimenting with the way you are holding the piece and the grade of sandpaper, I'd expect you could avoid that problem.

Go to the nail supply store it a drug store and buy a 4 grit nail sanding board for about $1.50 -
Patience at the bending iron pays in rounded dividends!

As many said: piece of sandpaper glued to flat surface.
Push the bone same length, at same angle (90°), with same pressure and same amount times from 4 different angles.
1.Left hand guides right pushes.
2.Turn the bone around.
3.Right hand guides left pushes.
4.Turn the bone around.
This goes quite fast and gives almost totally square bottom,
admit planing would maybe do it more square,
but the set up and the risk for cracking.........
If you are afraid for your nails and fingers,
make a holder by routing a slot in a piece of wood.

Take 8 mm down to 5 mm , a lot of sanding . I use a plane . Fast , precise to a reasonably close tolerance

Atoma diamond plate...if the saddle width is standard and the channel of your bridge is routed for that width, the atoma is a simple operation of apply pressure and flossing the bone over the saddle, it cuts, loads up a bit, but the stiff nylon can clean it. Then the diamond works it's magic again. You won't really wear the plate out if the only thing you abrade is bone as it is much softer than knives.

But it's also a good tool for knives. You can restore a broken tip in a few minutes.
