Sawmill

[czechsonofagun]

I could not resist to come back to my old stomping ground to show off

First, this is what it does:

 

[czechsonofagun]

It is based on an I beam I got for free and the whole idea is taken from Logosol.

 

[czechsonofagun]

Log moves up with 1" ACME rods.

The log dogs I may need to change or improve, but it works for now.

 

[czechsonofagun]

Cheap rulers help setup the thickness, 1 3/8" move up gets me 1" board.

 

[czechsonofagun]

24" bar with ripping chain will need an end support, it shakes bit too much.

I tried to use whole 372XP clutch assembly, but it would slip on slow down - this is the outer clitch piece welded to a spindle. It gives me the option to replace the chain sprocket rim as needed.

The whole electrical setup has to be updated, also the oil delivery is lacking - gravity feed only now - probably will have to get some kind of an oil pump.

I like it. I'm assuming you have a ripping chain on there. How is the chain oiled? How many HP motor?

 

[czechsonofagun]

The motor is 6hp and yes, using ripping chain.

Oiled is gravity fed and the bar has extended hole to get the oil to the chain, but I think it needs more pressure than gravity to lube better.

Your back Prokop!
Nice setup. Weld made. Have you got a good supply of timber.

 

[Mysfyt]

Interesting concept! What rpm is your motor?

 

[s219]

Nice work!

 

[stuckmotor]

Nice work!

 

[czechsonofagun]

Thank you, gentlemen

The motor is 3450 rpms, pulleys get it to around 8500 but that's open for experimentation too. Seems like lower speed prolongs the life of the bar and chain. Also the blade cuts away from the beam - shavings do not fly in my face and also the chain gets lubricated right before cutting but I was told that using it this way puts too much strain on the nose sprocket of the bar.

I have access to downed trees at the place I hunt, more than I am willing to wrestle with

You'd have no problem with an overhead support bar. Aquarium pump should work for oil. Run two drip points. One right on the sprocket through a larger hole drilled in the grease point. Pull the sprocket and braze on a fitting?

 

[czechsonofagun]

Yes, Egon, seems like I am overthinking it. Did some research and oil dripping on the chain is used in most cases, no need to run it through the oiling port in the bar since the saw is always horizontal.

 

[Egon]

Remember those spring loaded grease caps on equipment? One of those would also work on the sprocket.

Are you running a standard chain saw chain?
I believe they use a different chain on the Alaska Mill type saws but I am not sure.

Nice:thumbsup:

Yes - nice indeed. Very interesting too.
