Looking for educational material
Looking for recommendations of affordable books, learning resources, websites, etc. for hydraulics. Especially stuff that is geared towards the do it yourselfer.
A project based book would be especially cool. Something that gives resources for buying pumps, actuators, etc. or at least tells how to select and look for the stuff.
Ideally, I's like to be able to make a power log splitter from scratch and then move onto some more challenging projects that are usefull around the home and jobsite.
Thanks,
Mark S.

Morning Mark I asked Dennis a while ago about a hyd section on this site. I guess he's been busy. Maybe now would be a good time to get it going.
I just happen to be in the process of building a splitter but its a big one. Almost have the slide finished and am working on drilling 1" pin holes in 1" plate. That is slow going.
TomG knows Hyd and theory and Murf me thinks is the project mananger. There is a thread here some where about projects.
Have Fun Harvey

I did a search for basic hydraulics stuff some years ago. The JD FOS Manual (Fundamentals of Service) was the best I came up with. FOS is a series that are intended as basic service orientation material for beginning techs. I have the hydraulics and engine manuals. They are available from JD dealers. I do have some other material and may start looking for some community college texts if my minor hobby obsession with hydraulics continues. The FOS manual isn't going to tell you in detail how to take a valve assembly apart or how a draft-control hitch or a HST works, but it isn't bad either.
You might see if the CAD plans company has a plan for a splitter. At least with a plan there's some engineering done so you don't have to guess about geometry, loadings etc. When I guess I end up with something way over-designed.

Hi Harvey,
Yeah, I'm a little suprised there isn't a forum for this subject here too.
Are you building your splitter from plans or designing it yourself?
Hi Tom,
I found this log splitter plan at Amazon
http://www.amazon.com/o/ASIN/B0000AXFB3/103-1254200-9186225?%5Fencoding=UTF8&coliid=I218GDFI4GT0ID&colid=3I2T1KNQS8QFT
And this book which looks pretty good but is pricey.
http://www.amazon.com/o/ASIN/0071406697/103-1254200-9186225?%5Fencoding=UTF8&coliid=IOC8X5CHBSW14&colid=3I2T1KNQS8QFT
I also tend to way overbuild things. I do my work that way too. It's Why I'm not rich by now. ... 
I also found this electric powered hydraulic log splitter at amazon. It's around $450. I wonder how good it is. It had generally good reviews except for a couple guys who seemed to have received defective or damaged units.
I wonder why there are no electric (non hydraulic splitters)? Seems like a gear and worm drive set up would work for a splitter. Anyone ever tried this?

Mark I am taking the best features I've seen and used over the years to build.
It will have log lift, trays to hold unsplit, trays will eventually funnel into elevator for wagon, Also it will allow stationary operation and keep pushing up a pile.
My intent is to eventually us a 11-13 hp with a 20-22 gpm pump. But for now I'm going to use the Power Beyond hyd system from tractor. It will allow me time for fine tuning of system.
I've seen several types of lifts and none have really impressed me. So I am thinking about a boom with hooks that rotates on a shaft.
I've seen the electric ones in books. I've seen the ads, BUT I do not think those people that wrote the ads heat with wood. Looks like something city people would buy to split their store bought wood into kindling to start their cherry little fireplaces.

I have a vague recollection that I heard about a safety issue with those screw type splitters. Maybe somebody knows what it is or can tell me that I've got false memory syndrome. I'm with Harvey--I don't think they're very fast.

Mark,
I have a copy of a great book that is published by the U.S. Army, 2001. The book is in Adobe Acrobat format (.pdf) and is 174 pages in length. The book is intended to teach new hydraulic technicians all the info they need to know to understand and service hydraulic systems. The file is 1.5 MB's. I believe I got the link to a copy from another Tractor Point member but I can't quite remember who. If anyone would like a copy, send an email to my address and I will forward as an attachment.

Harvey, first of all, good luck with the splitter project.
Next thing are those holes, instead of trying to drill 1" pinholes you should try burning them close to the right size then backfill them with an arc welder and small soft rod, it will go MUCH faster.
As for your lift, try using a straight arm with a hinged end plate of about 18" in length. If you make a small travel mechanism in the hinge and hydraulic lift arm the first thing that will happen when you go to lift the block is the hinged plate will move upwards trapping the log in the 'elbow' of the arm instead of rolling away from the splitter.
Best of luck.

Hi Harvey,
I forgot to include the link to the electric splitter. I like the fact that it's quiet (and fairly inexpensive), but I'd hate to get one and find out it's a piece of junk.
Here's the link:
http://www.amazon.com/exec/obidos/tg/detail/-/B00006AVZC/qid=1073315443//ref=sr_8_xs_ap_i2_xgl86/103-9759024-4317422?v=glance&s=garden&n=507846
If I can build a good one for the same price that'd be more rewarding I'd think. Plys I'd know who to call if it ever needed repair...
I guess the issue with an electric powered splitter that's any good is that you'd need a pretty monstrous motor (5-10hp, 4000-7500watts). That'd be a pretty big motor and cost a lot I'd think. Or would a motor that size be neccessary?

Hi Tom,
Yeah I was thinking that a screw type splitter would take a while to move the ram back and forth, especially if there's a significant gear reduction required for neccessary torque. Would probably need greasing a lot too to keep the wood chips and everything from cloggiing up the screw mechanism.
I'm just curious why I don't see any such animals.
