Amazing Tools #7: The Circular Swing Blade Mill

« Part 6: The Bench SlideMount Part 7 of Amazing Tools series no next part

Just stumbled upon these tonight. I’ve never seen them before. Very clever! It’s basically a band saw mill with a circular saw instead which can swing from horizontal to vertical blade alignment, and thus be run across a log 2 times to saw out a rectangular piece of dimensioned lumber. It helps to watch these 2 videos to understand what I mean:

Obviously, no large through-cuts, so no very-wide slabs, but if you need to turn a big pile of pine, or a very huge tree into dimensioned lumber, it seems these are designed to be quickly set to swing and slide to make those cuts in 2 fast passes with a swing of the large lever between each pass. Push it forward, pull the lever, pull it back, and you have a dimensioned plank. I think I saw some 4×6s at the end of that second video, but it looks like the larger ones could make at least up to 8×8 beams.

There’s a good write-up on these saws by Peterson Sawmills here – the link at the end of the first paragraph goes to a PDF of the steps taken to saw out boards. The other name I keep seeing is Lucas, and their page on these saws is here.

One final late-entry – I found another video by Peterson of them milling a log into lumber in under 10 minutes. They really get going at about the 1/3rd mark in the video, and they have a bunch of other videos under their account that obviously I will be digging through next :)

Edit: Timberline has a version that makes both cuts in a single pass, using a secondary ‘edger’ blade pair, with several other little clever enhancements:

There’s a few company’s in aus that make these. One is called a Lucas Mill and its absoloutley huge in austrailia. I’m surprised you guys haven’t seen them in the US before.
Just about every saw miller that I know has at least one of these. There allways doing demo’s at the ww shows.
they come with slabbing attachments too,which is basically a huge chainsaw bar.

Those are pretty sweet on the big logs. You should check out one can do with a slabber attachment on a big walnut crotch.

One of the mills here is a swing mill that we use mostly on dimensional stuff . We employ a dedicated slabbing mill for wide specimens , two band mills for general stock , and an alaskan mill for really long timbers . Each mill type has its’ strong points and its’ weaknesses .

I’ve seen this type of mill before, and that sawblade in the first one would scare me senseless!

I think we’ve all thought about how great it would be to saw our own lumber, but I can tell you that there is no such thing as “free wood”. I helped a guy once on his bandmill and we were slabbing some walnut. A 3” thick slab that was 20” wide (give or take) and 8’ long took 3 guys to carry and stack. Wet wood is heavy.

It cured me of wanting to cut my own lumber very quickly :-)

Great videos. Thanks for posting

Seems you guys in Australia in particular know all about these.

socalwood – I had a feeling you’d either know what these are, or actually have one in your inventory. You didn’t disappoint!

Steven – that is one massive slab in my book.
