Title: Using hydraulic motor for Log stops
Post by: Rickcnc on October 12, 2017, 06:38:50 AM
I am considering using a hydraulic motor to raise and lower log stops as will an additional motor to move a log clamp. Iíll use a cylinder to raise and lower the clamp.. My thinking is the motor will give me more travel for the clamp.
Has anyone else build their own stops and clamps this way ? I noticed the timberking 2000 appears to be set up like this.
Looking for your feedback on the idea and some input on what size of motors I would need.

I tried a hydraulic motor for the dog on the mill I built. It would back off on big logs. A motor's not made to hold like a cylinder is. My 2 cents.

Rick.

For the log stops, i think a cylinder would work ok. You can have plenty of travel. If it's for log dogs/clamps I used old vertical sawmill parts, and modified these into horizontal ones, using three phase worm gear electrical motors.

If you are not mobile. Use electricity, it's far less hassle.

 Yes TK uses a hyd motor to raise and lower the vertical stops and it works just fine, doesn't need much holding power for the log stops. Almost any motor should have enough power, I'd get a slower rpm one as you don't want the going up or down really fast.  Steve

Hydraulic motors are expensive seems like a waste when a simple small cylinder could do the same job. My bandmill has two stops tied together that swing up from a handle in the front of the mill. Its simple and they are 12" high but they can be lowered for smaller logs. Save the motor for a chain turner or cable feed. Frank C.

 If using swing up stops which I don't like a hyd cylinder would work well and be easy.  With vertical stops a hyd motor would be a lot simpler and they can be bought for around $100 or less, not that much more than a cylinder.  Steve

Anyone know if Timberking has "factory made" vertical hydraulic log stops and log clamp for a TK 1600? They would surely be a time saver

My TK 1600 has a hydraulic log clamp.  The back and forth is hydraulic but the up and down is manual.  I wish they did make a retrofit hydraulic log stop kit for the 1600.   The manual log stops swing forward and are impossible to keep adjusted.   I'm thinking about getting mine straight and welding them.

Also it would only take one hyd. motor to run all the backstops, whereas you would need a cyl. for each stop or a complicated linkage system.

Same problem here, the log stops are definitely a weak link.

Was looking at the TK 2000 on the website. It has vertical stops. Would it be possible to put them on a 1600?

Iím certain that if you call TK they will have an answer to your question. They are a great company with really good people that know their equipment inside and out. If itís doable they will know and will have likely done it before. You should give them a call at their number on the left side of this page.

I got 1, High torgue, low rpm hyd. motor that runs a driveshaft, that makes my 4 log stops go up and down. Home made, no problems in years. Can get the motors for $99 if you shop right. Pics in my gallery.

I got 6 of the same hyd. motors on my home made made mill. 1 each for 2 log dogs clamp/unclamp. 1 for 4 log stops up/down. 1 for head carriage feed. 1 for saw head up/down. 1 cylinder each for 2 log dogs up/down. 1 motor, and 1 cylinder for chain Log turner.
