Finished a 600S that was froze up and had a different swivel base on it that was the same diameter at the base plate and even the lock downs matched but only had 3 mounting tabs.

Everything about this vise needed attention, came from a Wyoming oil well out fit and they are not easy on vises. It was never oiled so it rusted in place. Spent a week heating and pouring ATF down the barrel and finally it slid out with no beating. The horse shoe washer was cut out of a 3/16 plate and it did not fit very good, should be 1/4. I made a new washer, these guys are big, 3-1/8 diameter at 1/4 thick, welded up the groove and fit everything where it is suppose to be. While I was at it I made a new larger diameter handle, and added a ball and spring set up like the Parkers.

Made three jaws for it one having grooves for clamping bars or pipes. I just felt like making one, took a while to cut the 45 degree grooves.

Resurfaced the anvil and beat out the dust cap on a roll of lead, good way to pull the dents out.

Autopts gave me a swivel base but did not like the cast swivel holder for the carriage bolts, I posted this earlier so I will not talk much about it but show a finished picture, It will not break.

This 145 lb vise with a 4-78 date stamp finished up pretty nice and should last another 40 years.
