  • I was always led to believe the point of a frame saw was to have a slower feed speed, but this was made up for by the number of saw blades you could mount in the frame. Eg, one log could be broken down into twelve or so boards in one pass.

  • What cooling is provided for the blades? Serious heat would be generated here, but I didn't see any smoke. Timber looked like recycled power poles - if so, then very hard indeed, like Australian jarrah eucalypts, which were used extensively in Australia and New Zealand for railway sleepers. Wickedly hard on saws when dry! Good clip - thanks for posting it.

  • Type Of wood its cutting is Green Heart , which is 4 to 5 times harder and heavy than oak, wood mizer would find it very hard to cut these type of logs, trust me i know, i have a LT70 and still find it hard to cut these logs.

  • what the heck is this thing doing? I have a woodmizer & still dont know?????

  • My dad had a gang mill like this one in Guyana,If i'm not mistaken it was the Esterer S-71.Apparently this one seen here seems to be also in Guyana. SURE Bring back a lot of memories

  • "Note" Read from my first posting three comments down:

    It was called the "bullet" because if the carriage was returning "out of the cut", it would move as fast as you could blink an eye. The band-mill could cut a log traveling in either direction. I once seen a trainee, give the carriage to much steam. The carriage blew out the back of the sawmill building and into the Fraser River.

  • If anybody has a video of a band-mill head-rig and carriage propelled by steam, often refered to as a "bullet headrig".

    I would love to see one of these at work again. These headrigs were common on the west coast before 1980. Some could cut half a million board feet per day or more.

  • Pretty Neat;

    In the 1970's I worked for Rayonier Canada, Marpole Sawmill Division, British Columbia coast. It had a steam-belt driven gang-saw similar to what you have shown here, except much larger and used to cut cants. These cants were cut from a head-rig and carriage propelled with steam. The carriage had hydraulic dogs and could handle a 3 metre diameter log.......... We cut mostly Hemlock and Cedar.
