I designed a hydraulic drive system for my mill around a Charlynn 2000 series 24 cu in motor with a #60 roller chain reduction. The motor will need to be plumbed with a cushion valve to prevent the system's back pressure from building to the point where it destroys components. The system cost would be $1000 - $1500 if you purchase new components. I still plan on converting my mill however I'd like to get things up and running as is first.

You fellas that have converted to hydraulic feed do you have to use what they call a motor spool valve so when you release the valve things don't come to an abrupt stop.?? Frank C.

I was cutting yesterday and noticed my blade keeps eating up my inside saw guide. It doesn't look like it ever touches the outside guide. Could be a operator problem since this is very new to me.

"inside" meaning the operator side, not the log side?

Check out some of the hints and suggestions in this thread from the past few days and see if something in the mill setup tips you off as to what the problem might be on your mill. There is a problem, just need to find it.

The blade shouldn't be "eating" the guide, maybe rubbing it leaving a shiny ring on the saw.  Is the guide out too far on the rim of the saw so it's hitting the gullets?

First off, check your teeth.  If they are old or worn or even a few of them chipped, that can be part of the problem.  First thing I always do is change teeth to see if the problem clears up.  Many problems involve tooth maintenance.

If you still have a problem then your lead is probably a little too light.  Just because you have it set to a predetermined setting doesn't mean its the right one for your saw.  Your saw is leading out.  Throw a little more in and see if the problem doesn't clear up.

Hey guys, hadn't posted anything in a while just wanted to give an update. Everything  is steel except for the husk. We built the carriage out of 3x3 1/4" tubing, new axles with pillow block bearings.  I was able to find 100ft of 12'' channel for the track. I also changed the flat belts to v-belt configuration.  I finally was able to saw some pretty decent lumber.  The blade began wobbling and getting hot.  I took it off to have it hammered and found two hairline cracks near the eye.  Today I called BH Payne and ordered a new 7 gauge 48" f style blade with carbide teeth. I went ahead and purchased a jones grinder to go with it.  I also replaced the 4 cylinder Perkins with a 6-71 Detroit. The engine is still in the truck, I guess I'll run it through the 10 speed transmission.  I'm on here all the time, just hadn't posted anything. Thank y'all for  everything.

Good to have you back, was wondering what happened. I would build a doghouse around that Detroit so you can hear yourself think. You should have plenty of power. Frank C.

We always took the exhaust and extended the pipe so it was outside the mill.  We ran a chipper, which helped drown out the noise of the Detroits.
