Should have put a sharp chain on  ;) :D ;D

Heck yeah.  Looks great.  Boy you move some wood. 

[Corley5]

I did just short of 1,500 face cord/500 standard cord in 2020.  I'm on track to at least match that this year.

Looks like you keep a few bars on hand.

Makes my back ache!

Corley how many hp, psi and gpm is that unit putting out?  

Single gear pump or multiple?

[Corley5]

  Honda GX670 24hp, I've not confirmed the gpm but recall something about it being 25 or 28.  Which seems high for the hp.  Runs 2,800psi.  Double gear pump.  Big section runs the splitter and saw.
 I get about 500 face cords out of a bar unless there's a mishap ;) ;D
 Way less back aches than wielding a chainsaw and wrestling blocks on to a splitter :D :D 8) 8)

Dash 8 or so hoses to the saw motor?

[Corley5]

It's more complicated than that ;)  3/4" from the power beyond feeds a sequencing valve controlled by pressure from the saw bar valve/cylinder supplied by a 3/8" line.  1/2" feeds and returns oil from the saw motor from that  ;D  When the log is clamped hydraulic pressure actuates the spool in the sequencing valve and turns on the motor.

[mike_belben]

ahh.  


Cant trust the operator to use his own sequencing valve per the product liability insurance reviewers initial report.  

Forgot about that. 

;)

[Corley5]

I misspoke.  Pressure is supplied by the log clamp to actuate the saw motor and move the saw bar.  Clamping and sawing are done with one valve.  When Multi Tek first came out with the 1610 there were two valves to use.  You clamped the log and then pulled the valve for the bar and saw.  Block Buster's system then was far better.

Thats a horse of a different color.  Is the clamp cylinder and bar stroke cylinder teed in upstream of the saw motor? 

 the saw motor engages softly as the clamp gets tight? Or the clamp tightens then saw bar begins to move and saw motor comes on full force after a certain pressure rise?

Does the saw motor spin in reverse when you raise the clamp?

[mike_belben]

Im rereading and looking closer at the vid.. I think youre saying Oil pressure in the clamp circuit acts against a spool that starts the saw motor. 

[barbender]

Not sure and I've never even looked at how it's plumbed, but my Dyna works the same way. You bring the clamp down, and when it hits a preset pressure (I think it's around 1000psi) the saw motor starts and the bar starts to feed. The saw motor starts fairly abruptly, too.

Yes and no.

Maybe just as simple as a pressure switch engaging a solenoid diverter valve or something like that.

My Bell 1000 works as Mike describes it also. On a single valve. I can clamp and not engage the saw until a slight pressure increase.
