I noticed the new sawdust blower addition on the mill.  No more shoveling mostly. Good for you.  

Not bad for an old man.

I tell you what...woodmizer needs to make a blower and sell them with every mill that goes to a production based business.  It's sooooo much better than shoveling 5 yards of sawdust from the mill every day.

x2 on that. I have a blower on mine, but it involves a bunch of expensive hi-maintenance flex hose and electric power. An engine driven blower would be nice, I've spent some time thinking about that but nothing yet..

That would take some HP away from the band drive for sure though.  I like being able to use mine as a giant vacuum, not to mention it also is on the moulder and planner, soon to be on the edger,  so having it run on electric has it's advantages too.

the motor crapped out on it.  They sent new motor and when I went to take the sheave off of thw old one that some buck welded itself onto it.  I tried heat, hamburgers and onions.  It finally came off but it was messed up.  I filed it back to how it should be but now the roll pin hole is enlargened and not a tight fit and wont keep a roll pin in there anyways.  So I just asked them to send me new.  They took my $ and held it captive for weeks while the sheave has been backordered.

I assume you are speaking of the in/out motor and not the business unit. I had lots of problems with the in/out mechanism on my 2003. About 5 years ago I switched over to an air cylinder and a screen door closer for in/out./ It has worked very well for me. It has been refined since this vid(was still developing/refining). I use the stationary house air compressor(big unit) and an airline through the cat track that now supplies air pressure though a regulator to my air bladder for blade tensioning.

So Im looking at the dust extractor, and the greenchain on the outfeed side, and a few other changes I see you've made since the last "how it fits together show" and I got to say it's starting to look like a sawmill mate. Thats a pretty impressive demonstration of the real world capacity of that mill, and you've got some flow happening: theres a whole lot of capacity increase happens just with that flow increase and I imagine you're getting a whole lot more work for a whole lot less effort because of it. Congratulations!

Whats next? 72" McDonough double sided band headrig? Gangsaw? Quad with chipper reducers? The mind boggles at what you'll be able to achieve by the time you get to 200. :D

I've seen tubevids of the hurdle in action: they're a producer if you got the right logs to feed it. Of course you'll end up right back where you were before in terms of needing a whole whack of expanded support gear to make it run at capacity but.... thats what we do right? Everything the hard way until we bed it down then off on the next expansion :D

I had a guy was a bit of a mentor to me in another industry years ago. His advice was "bite off more then you can chew then chew like hell before it chokes you". He never mentioned the indigestion that comes with it at times, but nothing ventured nothing gained and all that. I'm just about back on my feet after that hiding at the start of the year, and when any sane person would be consolidating just to take a breather I'm bidding blocks of timberland that I've got no idea how I'd process the volumes, but guaranteed supply is the best kind of problem IMHO. 

I've said it before : this industry isn't a career or a job - its a disease!

Elevated construction sure makes life easy but the setup $ hurts. Pays in the long term though.
I've been tossing my "one day" greenmill setup around in my head for years, which involves a series of benches cut into the side of a hill. Log yard at the top, head saw on the first bench, resaw on the next one down, then drop a level to docker or edger or whatever, final level being stacking area and an open yard behind it for storage. Gravity assisted chains going down the hill from station to station etc etc Bays probably 25' wide which makes for cheap shed construction, floor bench levels say 5' elevation difference... but you could recess back into the next bench up for sawdust extraction including walk beside access to the scraper chains or to get at the bottom wheel of a big vertical band etc.
I saw the original idea in a US Forest Service or similar article from the 50's or so about mill layouts and I never have been able to find that article again.... but I remembered thinking how sensible it was to make use of gravity to flow your material, and being able to get at the underside of gear without either a pit that wants to fill with water when it rains or the one time cost of elevated construction. The big problem with elevated construction aside from cost being of course that you kinda gotta start with a plan and its pretty hard to vary from it once you've installed the first piece of gear.
I think for all of us it'd be nice just once to be able to set up right at the start wouldnt it?  I can afford the dream, anyway.

Gonna try to get my neighbors debarker..mainly for exporting logs though but will also use it for tie logs or really dirty logs.  If you hit metal you just change the couple bits that got nicked and keep going.  Can swadge them later on to reuse.

Most likely..I been thinking about getting one for a couple years.  I tried to convice the pallet guy to buy one a few years back and have me run it but he said he's in the biz of making pallets not sawing lumber.  He has a scragg mill though

Though you said a pulley was roll pinned on a shaft and failed.      Will this be the first hurdle in n.y.s.?

 4x4, the last time I watched an automatic carriage/ vertical edger run they dropped everything on a belt that ended into the mouth of a chipper. Two men pulled the lumber off this belt and never touched the slabs or sticks. More than once I have passed up buying a v. edger because I often saw alone so I accumulate flitch boards and edge latter. Sawing with a v. edger slows the sawyer down some but is much more productive.

Hurdle makes tie mills, they have one purpose rip a 7x9 out of the log as fast as possible,  and ties have a tolerance of +/- 1/4". Maybe a good reason you don't see any in the land of high dollar hardwood.
Title: Re: LT70 Super Sewing Mochine
Post by: 4x4American on November 03, 2018, 10:14:23 PM
I would agree, JB, that a 40' 2HB Hurdle is mainly a tie mill, yes.  They also make 48' 3HB and 60' 4HB mills that are designed for more than just ties, like pallet cants, crane mats, grade, primary breakdown feeding a resaw/gang, dimension lumber, etc.  Having a 3
blade edger, I could pump out toober fours like a bat outta hell.  They even offer a top saw and lo-pro vertical edger from the factory.  Simple setup, simple transportation.  Best modular mill I've know of.  If you see one in person you'll see it's beefy, like that one in your neck of the woods I almost bought.

moodna crick I like that idear..except for 2 things..if they miss a good piece, kiss it goodbye.  Maybe one of the pullers needs to take a leak and the sawyer don't notice.  It won't accumulate on a green chain, it'll just be chipper food.  I like the idea of having a slab dump at the end trimmer.  That way the end trimmings and the slabs find their way to the chipper in one spot, and the trimmer main gives you more bang for your buck, and gives sawyer one less thing to keep track of.  I know of multiple guys who saw solo with a vertical edger, and they love it.  It's two steps instead of three, saw cab, green chain, saw cab, green chain...cut lumber in one shot from the saw cab. niice
Title: Re: LT70 Super Sewing Mochine
Post by: JB Griffin on November 04, 2018, 10:42:33 AM
4x4, none of the products you mentioned demand much in the of accuracy.  For example,  pallet cants down here +/- 1/4" unless they get picky on us, crane mat timbers +/- 1/2" and don't even have to be all that square, grade +/- 1/8" unless its a special order, primary breakdown just take the bark off and make it squareish, dimension lumber all gets run thru a 4 head moulder anyway. 

As you can see WAY different specs in the south where those mills are made.

Post by: JB Griffin on November 04, 2018, 11:00:00 AM
When we get an order for bridge timbers we saw them on the the Dominator cause the meadows can't hold the +/-0 tolerance they want.
Title: Re: LT70 Super Sewing Mochine
Post by: moodnacreek on November 04, 2018, 03:58:20 PM
4x4; the sawyer would have a push button or foot pedal to stop/start the belt. [I have a overhead lever] I could never figure out a way to handle v. edger output on my set up.    Am very interested in your project.                        P.S. The old timers always called it the 'crick'.

Post by: longtime lurker on November 04, 2018, 05:07:22 PM
Do they have a linebar? You can do a lot to improve dimensional tolerance if you have a linebar: SOP here with this springy eucalypt stuff is to vary the pressure on your carriage knees against the linebar to compensate for log spring, which gets rid of a lot of the thick and thin issues that cause dimensional variations.

Yea I'm not really worried about it for what I'm doing..what I mainly cut is cants grade and ties.  None of which have to be perfect.  The pallet shop I sell to now sends the important size cants through a sizer first anyways.
