I think I've got SYP to rebuiled my old Chase circular mill.The power co. replaced poles and crossarms on the highlines and left a big pile in the field I hay.Crossarms are 31/2X9"and 40' long a little weathered on the outside but solid on the inside,I'll true them up on the bandmill.How can I tell if its SYP ,it taint native up here in the northeast,it does have a pine oder no knots and came from a large tree??Their is no treatment on or in the wood I can detect.Frank C.
