Scrapers

[Joseph Garrett]

Joe,

May be a very large saw to find these deepness 4 " (once the teeth are
grounded I guess)
Do I understand well that these are flat blades may be 3' long, for
metal ?
Is it better to get HSS then ?

May be better ask for used one at the grinding shop (I have to find
one for my ribbons ) I use yet old saw blades for scrapers, but the
steel of those blades is probably good indeed.
The little lathe is beginning to be wanted too !

But this in fact does not level the bridge if hand held (or one may be
really very good and have good eyes).
I believe that a rabbit for end grain or a scraper fixture may be
useful if one want to level or plane bridge top or bottom.

Isaac,
Pretty much wrong on all counts! I suspect the language difference is the
reason.
1. Power Hack Saw blades are about 12" long, (they vary), by about 1 3/16"
wide, by approx. 1/8" thick. They are used in Machine Shops for whacking off
large steel/brass/iron/?? stock.
They can be purchased from many sources. They are definately HARD steel! (I
made a knife out of one, once. It is a bear to sharpen, but once it is, the
edge last forever!<G>)
2. Using one of these is very CONTROLABLE, (once you get the knack). If you
already use the flexible type, the transition to these is simple and less
demanding, physically. I use these to scrape olde soundboards of the olde
finish and to get them ready for sanding and finishing. When they are
sharpened properly, they cut very well and leave a nice smooth surface. Of
course, if you are visually impaired it is more difficult. However, several
years ago, I gave a seminar at The Piano Hospital, Vancouver, Washington.
The greater majority of the students, there, are visually impaired/blind.
With a little guidance they all were able to, not only scrape the board, but
put in shims and level the board for final sanding and finishing. We used
these Scrapers for the majority of the work. (This was done on a Packard 6'
grand!)
Because these scrapers are over an inch wide they are ideal for
leveling/canting/surfacing/scraping that last millimeter of cap, etc., as
the bridge is only slightly wider than the scraper. Believe me, once you use
one of these you'll never go back to the other methods, IMHO!
