I think white ash is a popular wood to use. I have a bunch of go-bars made from red oak that work very well. Pick a wood that doesn't splinter/crack easily. My oak may not be the best choice as I had one bar crack and launch across my shop. Fortunately no one was in the trajectory of the very sharp spear that went flying!</FONT></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2>Mine are about 18 millimeters square - but that just depends on how much pressure you want to apply with each go-bar. I'd recommend cutting an experimental go-bar and test numerous dimensions until you find the pressure you are looking for. You can vary the length a little bit also to vary pressure.</FONT></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2>Are the go-bars for ribbing a panel? Have you considered going pneumatic? I know a guy who has a couple ugly but very stout pneumatic rib presses for sale - or make 'em yourself - they're really pretty simply to construct.</FONT></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><IMG alt="" hspace=0 src="cid:00d101c65715$4a0466d0$0201a8c0@DESKTOP" align=baseline border=0></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2>Terry Farrell</FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black"> </DIV> <DIV><FONT size=2>List, I'm ready to make new go bars for an old sound board press.
