This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hey Greg. The clamp at the URL I sent is simply a clamp that appears = very similar to the clamp I had found nearby to me. It is not the same = clamp. It is not from that (URL) source. The clamp I found does indeed = cost only $7. I also looked at the K type clamps. The ones I looked at, when you put = some pressure on them, the jaws did not remain parallel to one another - = the formed a small but significant angle. Yours may well be better. My attraction to, and reason for trying to evaluate these others further = is the $7 X 25 =3D $$$ factor. As far as digging into the rim underside - a little block between clamp = and piano solves that problem.

My thoughts are = that the K body clamp has a built in plastic pad surface and it's wider = to grab a larger surface area to prevent slipping. You wrote that it = only cost $7 but the savings was $7 not the cost. The reach is greater = on your clamp than the "k" body but the iron jaw could easily dig in the = underside of the rim. I have 2) 12" clamps of the style you offer and = like them a lot. They are very strong. I just thought that the extra pad = protection was worth the effort of ordering the "K" bodies. I paid = roughly the same for the same length clamp.=20 Greg=20 Farrell wrote:=20 I am hoping someone might have some input regarding suitability of = some=20 clamps I have found at a hardware store for clamping a new = soundboard to the=20 rim during gluing. A clamp that appears nearly identical can be = viewed at:=20 = http://www.amazon.com/exec/obidos/ASIN/B00002245H/ref%3Dnosim/toolstoolst= oo-=20 20/103-5531792-1187059=20 Greg - these are the clamps I was referring to.=20 The clamp I am considering has a reach of 4-3/4" from the inside of = the bar=20 to the center of the screw adjuster thingee (I believe it is = referred to as=20 a 5-inch clamp). The bar is 24" long, 1-1/8" wide, and 1/4" thick. I = put a=20 36" version of this clamp on a 32' wide table at the hardware store = and=20 torqued down on the screw adjuster thingee and was only able to bow = the bar=20 perhaps a quarter-inch - maybe 3/8". So I would think that one of = these=20 clamps only opened to 14 inches or so, like you would typically have = on a=20 piano soundboard installation, you would find very little bow indeed = (is=20 that not the worry with a too-light-duty clamp?).=20 What makes or breaks a clamp for installing a soundboard? Enough = reach?=20 Strong enough bar? What else?=20 These clamps are significantly heavier duty that the orange bar = clamps that=20 you common see at Home Depot type places. Not a whole lot more heavy = duty,=20 but a significant step up. Still a far cry from a $60 hand made = German=20 clamp. But I suspect they will do just fine. Any opinions?=20 So maybe I should buy one. And do what with it? How can I reasonably = evaluate it without just buying 40 of them and putting in a = soundboard? Any=20 ideas? Any thoughts Greg?=20 I think this clamp is A-OK. It only costs $7. I would sure like to = find out=20 that it is A-OK, but I also don't want to find out the hard way that = it is=20 just a tad weak on performance in this application.
