Just bought a 6-71 detroit for 500.00 now got to get the rest of the mill and parts one day I'll run my own rig been my dream since a little boy. Old man down the dirt road had one my job was a board stacker at 8 years old. Dirt poor but the old man paid me top dollar back then of 5.00hr! 6am till 7:30pm! Then I'd walk down the dirt road home.i was home schooled back then so I worked m-f. The old timer died soon after his wife and some Yankees bought the land and literally pushed it with a bull dozer! Just to build a retirement apartment center. They would go under and I would get my revenge as later bought the abandoned apartment and bulldozed them down. Now in memory of old man Jack and his wife Mrs Betty who helped me and my kin survive many winters I am building a sawmill where his once stood! I farm the back field now where the logs use to be stored

Great video. Not sure how you keep proper blade rpm with a hand throttle but I guess it works for you. Love the sound of a 6-71

Regardless of how the mill is being run, that is one fine sounding engine.

best sounding wood saw ............EVER

man i could just dim the screen and lay back and just listen to that beautiful scream of that half a dozen runnin'! lol

One of the nicest sounding 6/71's on KZread.

Need a governor for that old Jimmy!

U need bigger logs where U can open the throttle and listen 2 it sing 🎶 😌 😏 😉 👌 every time U saw a line even when idles it 🎶 sounds good 👍 the sweet 😋 sound of the gm diesel 671 most all of the old sawmills used them I remember that sound very well growing up years ago they sound even better on the days when U wind 2 push the sound when the wind is just right I could hear it on the other side of town singing in the wind TLC/OMG 11 9 2O22

Saw blades are hammered to run at a specific speed, find a power unit governor and like others have said run at a constant speed. Also make sure you have the emergency kill flaps incase an injector sticks.

Great video! Would love to see the engine and hear what it sounds like wide open while sawing. I have a 6-71 in my 1978 GMC 9500 dump truck and its been a great engine so far.

Accurate lumber cutting is somewhat controlled by the speed of the saw. You need to find that rpm (maybe 540-600) and hold that blade speed constant, even when you're turning the logs or loading the carriage....no load on the saw with constant speed helps with blade cooling. My dad had a sawmill very similar to yours, nearly exactly, in the 1950's. It was a 5 person operation; log turner, sawyer, edger man, and 2 men tailing the edger and operating the trim saw. He always dogged the logs on the carriage with just the front block, unless the logs were extremely large (22""+) or long (20'+). All the extra work you're doing (extra dogging) is knocking down production and efficiency. His logs, all southern yellow pine, were 16" down to 8" (one 2 X 4 and two 1 X4's if it was straight and he was lucky).....average. He sawed about 7000 bd. ft. per day. If he made 7500 bd. ft. it was an awesome day. (8200 was his largest amount ever) I love your mill, I hope you'll post many more videos. I could watch this all day!!!!!!!!!!!!!! Two thumbs up....that's all I have..........lol ...13

Thank you for the comments. I really just saved the mill from deterioration and saw occasionally just for fun. If I were in it for production I would implement many of the suggestions you and others have listed. This is how I spend my "personal" time away from the normal 8-5. I love tinkering with the old mill, oiling, greasing, sharpening, etc. sometimes I don't even cut anything with it, just maintain it and fire it up now and then. I have restored 3 mills now, the previous 2 were sold to others who wanted them for production, I hate to see these old machines rust or rot away.

6-71 plenty of power , needs to run constant speed!!! as mentioned . Blades are hammered to run at certain RPM 600 650 ext. You don't want to be over speeding that blade!!!! LOL

the trucks I drove that had 6-71 Detroit was 238 HP the mill we used to cut 16 ft 2x10s Burr Oak one end was 10 " the other 11" on 16 footers. so we were cutting wedges for the deck on my trailer whey worked fine.

MOST Sawyers like the gm diesel 671 powerunits to run at half throttle plenty of power she will a sawmill just fine when Sawing Big logs it will sing all day long you can hear every line you saw let her sing OMG 1 17 2022

Get rid of that variable speed governor, and install a limiting speed governor. Run that engine at 1800 RPM, just where she likes to be.

she only likes to be there if she's under a steady load. run a 2-stroke detroit at a steady 1800 rpm with no load and you will eat up piston rings and liners, and if it goes on for too long it will eat up the pistons as well. the dude in the video operating the sawmill knows his job well and doesn't abuse the equipment.

@@marzsit9833 The blade on a circular sawmill is hammered to run true at a certain, fixed speed. Running it at varying speeds will cause runout. Also, many hundreds of thousands of Detroit engines run at one speed on things such as generators, air compressors, pumps, and even sawmills.

Did not see a splitter behind the head saw... hope you do indeed have it there. Doing good, but there are several improvements that you can make to sawing more efficiently. You'll get there..

Circular saws are hammered to run at set rpms (usually 540rpm ). Also your blade needs the rpms it is hammered for to 'open up' and run cool . Never lug a 'jimmy', they are two stroke engines.

The rpm on these type of saws is set by the wood you intend to saw which dictates the feet per minute of the rim of the saw. 8,000-10,000 feet per minute is the range. Our 48” saw spinning at 750 rpm is traveling 9,420 feet per minute, an excellent choice for softwoods.

YOU need change to air dogs it will save you alot of walking back and forth and also need a extra man for a log turner makes it easy for you save your self alot of work when Sawing Big logs 1 17 2022

I would change that sawmill over 2 air dogs it would save U from alot of walking when U don't have help or a man log turner it will be a great help that U could get more done and more lumber sawed in a day's time 😉 OMG 11 9 2O22

What kind of head is on that thing a 2 or 4 valve

LOVE YOUR MILL COULD YOU SHOW SAWDUST REMOVE& CONVEYOR DRIVE? i HAVE A MILL THAT I AM RESTORING ALSO WITH 671

set the rpm and let it run your not saving any fuel doing this but then again it's your business you must have deeper pockets than most

Open her up make your saw run better. Are you doing that for a reason?

ADD A FEW MUFFLERS, I WORKED ON DETROITS FOR 30 YEARS. EVERY STROKE IS A PWR STROKE, BUT TO ME THE SOUND IS ANNOYING, ALL DAY LONG

up and down revolutions of that saw will ruin it. Get an oil governor and put on the old girl and let it run steady. You aren't saving fuel like that.
