---------------------- multipart/alternative attachment =20 Terry, David My procedure is similar. I locate the bolt holes thru the bosses & mark= =20 the board with a Forster bit. I with the plat removed I drill small pilot=20 holes in approx. the same place I drill for the acoustic dowels later. No=20 filling.=20 I use a bar clamp and block to hold the board tight, as close to the plat= e=20 as possible in the back bass corner. I use a piece of square rib stock with= =20 blocks & clamps on the long side. On the belly I relocate the original damp= er=20 guide rail screw holes & use the rails to hold the front down. This way=20 there are no obstructions for my bearing string.=20 At this point my treble soundboard trim cap is already glued & screw holes= =20 relocated. I use this for my dry fit & I am VERY careful to get this entire= =20 corner snugly down as tight possible. I also put two screws in the board at= =20 the treble corner board trim piece to further insure that this spot is tigh= t. =20 Otherwise one will cut the bridge cap height to short every time. I guarant= ee=20 it. The trim cover the holes later. One screw is adjacent to the very end o= f=20 the bridge the other spaced about 3 inches back. The plate is then set in on its nose bolts & I attach it to the flange=20 with a screw on either side of each strut & one top and bottom. Usually abo= ut 8=20 screws. I use the nose bolts to set my elevation so the rear plate just sit= s=20 on my 1/8 wedge. If there is a treble bell bolt this goes in as well. I usually put the=20 plate elevation so the rear bolt boss is on approx. 1/8 inch wedge. I clamp= this=20 down with a block & clamp. The nose caps go on at this point & lock in plac= e. I then use wedges to pre stress my board, cut the notches in the bridge=20 top. This set up leave a lot of room to work. Dale Erwin On the soundboard that I=E2=80=99m currently doing I=E2=80=99ve secured the= board to the=20 rim with screws and cardboard washers=E2=80=94as in front rail punchings. =20= A few small=20 screws (#8 x 1 =C2=BC=E2=80=9D and they have that built in washer at the he= ad) into the=20 rim in the area under the plate about every 12 =E2=80=93 18=E2=80=9D or so=20= (I can=E2=80=99t remember=20 the exact spacing), and a clamping block on the straight side and the cutof= f=20 area where the plate is not in the way. I drill the hole through the pane= l=20 large enough so that the screw is not actually cutting or binding in the=20 panel, only in the rim. Once the board is in the holes can be filled and w= on=E2=80=99t=20 show anyway since they are under the plate. =20 =20 David Love davidlovepianos@comcast.net =20 Erwins Pianos Restorations=20 4721 Parker Rd.
