Thread: logosol M7 or wood workers mill info/pics

The Logosol mill uses a patented system of pulleys and a winding handle to raise the log beds. When you get the log where you want it it is held in position by a ratchet assembly that works in 1/4" and 1/8" increments. The saw is held to the traveling slide by a pair of adaptor nut/bolt gadgets that screw onto your bar mounting bolts in place of the original nuts and then fit into holes in the slide and are secured by the original nuts.
The design is pretty good but to reproduce it in a home workshop and do it "on the cheap" may well be a challenge. I attacked the problem from a slightly diferent direction and strangely enough, it seems that my design has potential! As I write this I still have sawdust in my hair from the first trial run of "Hill's Mill"!
My design involves a traveling platform running on a rail assembly which can be adjusted in height via a trailer jockey-wheel assembly fixed to the platform. The platform uses 12 wheels, 4 on top, 4 underneath and 4 more to keep the platform centred on the rail.
The saw is removed by undoing one bolt and can be adjusted so that the bar is parallel (or not parallel if you want tapered boards) to the log bed. The whole thing is trailer mounted and cost me less than $50.00 because I managed to scrounge most of the steel. Did I mention that I have a Master's Degree in Scrounging from the University of Applied Poverty? No? Oh Well, bad luck, 'case I do!
Now. After I sliced up this lump of Silky Oak (Grevillia Robusta) I took some photos with my almost new digital camera and they look really good when I look at them in the viewing screen thing, don't you think? Oh! You can't see them? Oh, dash and blast! Does this mean I need to get them out of the camera and onto the computer? Hmmmmmmm, be back in a while. Gotta work out how all this happens. It will happen, just don't hold your breath! Blue is an inapropriate colour for the average healthy human.

i have an old boat winch i am thinking of riging up.

however i am now thinking of doing a4stroke powerd mill instead as i have 4 8hp brigs motors here doing nothing. lots more work and cost thow.

here is my basic desighn.

a cable fron the winch would be passed threw the loops on the legs and back to the winch in the middle to alow height adjustment. i would have to replace the cable on the inch with 2 cables one for each end but that shouldnt be any hastle. i have kept most of it in timber as it is easy to work with and free. and i have also kept welding to a minimum.

just gotta desighn the carige thingy now. i think ill have the aw attach via a bar clamp similar to the alaskan mills.

it all coming together and at the rate my tablesaws going ill be on to it in a coupla weeks..

anyone got some 3m lengths of angle iron lying round. ivonly got train line.

and here is the saw cradle thingy.

the peice that holds the saw and the winch.

I thought about making up someone along the lines of a logosol.

The disadvatage is the logs need to be lifted off the ground onto the machine.

So I'll build a Gantry/rail setup like the b/s mills and attach a cs to the gantry.
I'll only need to roll a log onto the chassis, which is simple enough with a cant hook.
Down the track I might even convert it to a bs mill if the cs is much too slow.

Though I don't intend to do a lot of milling, just the odd nice log that turns up, so I'm not in any hurry.

i thaught that to but where im gunna put it the logs wil roll level onto the log deck. where i do mosta my milling is a pad cut out and i can put it just over the bank for the deck is level with the ground.

only down side is ill have to build a platform to walk on but i will do it with gaps between the boards to stop sawdust build up.

sounds great

if i used a peice of upturned rail line for the rail on the mill it would be verry strong and dead streight as its going to be hard to find a streight peice of wood for the rail. only down side is the wheels would be 75mm apart. this might cause problems with overbalance. and might not stand the leverage.

ill do a diagram to explain it better but i need some opinions on what others think.

Mate, if you have enough railway line, use TWO lengths about 300mm apart, perhaps more if you are going to consider a bandmill. If you want to make a gorilla size chainsaw mill you might be able to fabricate an adaptor gadget so that you can use a big 4 stroke motor to drive the chain running on a standard bar.
Just make certain the thing is well braced! By the time it's finished it should weigh about 3/4 of a Ton!
Dennis.

here it is

iv got about 100m of rail line here. i might make a 4 stroke version late on but for now imm happy to have this. if i can do it like this i have all the parts to =make it here so itll be free. and by having only 1 rail i wont have to cut any rail line as there is only 1 3m length. the rest are over 5m.

Most of the weight of a saw is in the motor. If you keep the saw with it's centre of balance located above the rail then things will be fairly even and shouldn't put too much strain on the wheels.
Good luck with it,
Dennis.

my main consers are the forces created during milling. there would be a fairly large pulling force i would think.

would making the carige longer help?

What design program you using, if you don't mind me asking?

I'm designing a Horizontal bend-saw with 1,20 meter wide cutting capability, and 5 meters long, using a 18HP petrol engine. I got some god ideas from seem some of this type home made machines on the YouTube, there are a few there that are very simple and very effective so, I'm going to give it a go...!
