I use 150 garnet, get it from Abrasive Products, (317) 485-7701. It leaves the surface very nice, not glassy smooth, but about like after sanding with 150 sandpaper. Last time I ordered several years ago I got 100# for less than $50. I use it outside and don't bother with trying to reclaim it, though you could recycle it indefinitely. </FONT></SPAN></DIV> <DIV dir=ltr align=left><SPAN class=958163720-13032011><FONT color=#0000ff size=2 face=Arial></FONT></SPAN> </DIV> <DIV dir=ltr align=left><SPAN class=958163720-13032011><FONT color=#0000ff size=2 face=Arial> <DIV align=left> <DIV> <P class=MsoAutoSig align=left><B><FONT color=navy size=5 face="Lucida Calligraphy"><SPAN style="FONT-FAMILY: 'Lucida Calligraphy'; COLOR: navy; FONT-SIZE: 20pt; FONT-WEIGHT: bold">Dean</SPAN></FONT></B><B><FONT color=navy size=5 face="CAC Leslie"><SPAN style="FONT-FAMILY: 'CAC Leslie'; COLOR: navy; FONT-SIZE: 20pt; FONT-WEIGHT: bold"><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></SPAN></FONT></B></P> <P class=MsoAutoSig><FONT color=navy size=2 face=AGaramond><SPAN style="FONT-FAMILY: AGaramond; COLOR: navy; FONT-SIZE: 10pt">Dean W May                (812) 235-5272 voice and text</SPAN></FONT><FONT color=navy><SPAN style="COLOR: navy"><o:p></o:p></SPAN></FONT></P> <P class=MsoAutoSig><FONT color=navy size=2 face=AGaramond><SPAN style="FONT-FAMILY: AGaramond; COLOR: navy; FONT-SIZE: 10pt">PianoRebuilders.com    (888) DEAN-MAY</SPAN></FONT><FONT color=navy><SPAN style="COLOR: navy"><o:p></o:p></SPAN></FONT></P> <P class=MsoAutoSig><ST1:PLACE u1:st="on"><?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" /><st1:place w:st="on"><st1:City w:st="on"><FONT color=navy size=2 face=AGaramond><SPAN style="FONT-FAMILY: AGaramond; COLOR: navy; FONT-SIZE: 10pt"><?XML:NAMESPACE PREFIX = U2 /><U2:CITY u1:st="on">Terre Haute</SPAN></FONT></st1:City><FONT color=navy size=2 face=AGaramond><SPAN style="FONT-FAMILY: AGaramond; COLOR: navy; FONT-SIZE: 10pt"></U2:CITY> <U2:STATE u1:st="on"><st1:State w:st="on">IN</U2:STATE></st1:State> <U2:POSTALCODE u1:st="on"><st1:PostalCode w:st="on">47802</U2:POSTALCODE></st1:PostalCode></SPAN></FONT></st1:place><o:p></o:p></P></DIV></DIV></ST1:PLACE></FONT></SPAN></DIV><BR> <DIV dir=ltr lang=en-us class=OutlookMessageHeader align=left> <HR tabIndex=-1> <FONT size=2 face=Tahoma><B>From:</B> pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] <B>On Behalf Of </B>John Ross<BR><B>Sent:</B> Sunday, March 13, 2011 4:10 PM<BR><B>To:</B> Pianotech List<BR><B>Subject:</B> [pianotech] Cleaning actions, and hammers<BR></FONT><BR></DIV> <DIV></DIV><SPAN style="FONT-FAMILY: Arial" class=Apple-style-span>Original question<BR></SPAN><SPAN style="FONT-FAMILY: Arial" class=Apple-style-span>John Ross, I do like the idea of using the sand blaster with glass beads.
