Homemade log processor saw issues

[william petts]

Ohh I see........ so yours is one of a kind, was it a pig to build?

[Chipy]

Yes it's one of kind. Father in law built it for me and has never built anything like it before so was just trial and error really. Only tested it after it was built and we were lucky most of it worked.

Had no luck finding a hydraulic saw so if anyone knows of one new or second hand then let me no please

Yet the manufacturers minimum requirement is 38-53

 

Even at the minimum guide bar length you are still under power

 

Sounds like you need to cannibalise a harvester head for the motor and guide bar

 

 

You could also make your own easy enough

Does anyone know of any company's that would sell me the parts to build a saw and I'd then have to put them together? I've already tried Riko, Caledonian forestry services, fuelwood, JASP Wilson and four seasons fuel. Know one seemed keen but not sure why, seems simple to me. The only thing I would want before hand is the oil flow and pressure requirement for the motor so I know if my digger hydraulics will run it. I've been put off harvesting head saws because these require 200lpm to run them which I know I'm no where near but until I find someone to test my digger for me in Cumbria then I won't know.

I wouldn't no where to start with making a saw. Which motor etc

[Chipy]

Another saw on eBay but it's £650, it would need brackets making etc and its 2nd hand so could be as useless as the one I have!

I was thinking about what would be needed to make a saw and I have the bits that are the hardest to find and get right such as the sprocket, bar, chain and the frame so all I need to do is remove current motor and make a new motor fit. Can anyone show me what type of motor I would need with prices. I'm hoping there no more than £200 otherwise might have to be a 2nd hand one.

[Chipy]

This is what I need to do but all I need is the motor and to make a bracket to attach it to saw so anyone know what spec that motor would be?

[Chipy]

Anyone know how that saw above would be oiled because that's the other thing I'd have to make. I prefer idea of tank above but I think I'm right In saying I would need a tiny pump to pump oil into saw?

[Chipy]

It would be nice if this saw in the link would do because it's nice and cheap but how do I know what size of motor I need? http://www.ebay.co.uk/itm/Hydraulic-Motors-BMR200-Series-200-CC-REV-BMR-FFRM-MR-OMR-25mm-shaft-/262253837118?hash=item3d0f8bfb3e:g:-24AAOSw5VFWKC2f

 

The motor in the link seems to be what the Americans use in there homemade processors but for its price I can't help but think it's overkill for what I need. Il be processing 150 tonne/year maximum. If i have 2000psi and around 60-70 lpm of oil flow then how do I know what motor that will run ?

You need to stop thinking, "this is what I have" and start thinking, what do I need, the time for "this is what I have" was before you made such a big splitter.

 

What you are trying to build amounts to a commercial scale processor the pump and motor need to be matched to the machine you have built

 

The motor in your link is listed as suitable for augers and suchlike, its a low speed high torque motor and isn't likely to be overly successful as a drive for a saw, which tend to be a lot quicker. Chain speed is going to be a major factor in cycle time

 

Take what you have to a hydraulics specialist and get their input, it will save you aggravation and money in the long run
