Made up an Excavator boom cross tube yesterday afternoon.8x4 heavy wall mechanical tube 21-1/2" long.Trued the OD to 7-7/8",thru- bored the ID to 4.1" recessed bored each end to 115.2mm x77mm deep.Recessed and chamfered each end on the OD to accept the outer O-ring dirt seals
Drilled,counter-bored and tapped the zerk holes,deburred those,heaved it over on to the press and pushed them in.0025" interference and 271 Loctite just for fun.
4 hours 45 minutes including mucking around looking for the chip breaker for my boring bar after it landed in the chip pan under the lathe.
Troubling part is it only weighs 220 odd lbs and I dam near broke a sweat boosting it into the press,must be gettin over the hill
