Parts 6 and 15

I'm a happy man thanks to M Large in Ireland. They were more than happy to supply me with a complete new saw unit off a Hakki Pilke machine costing £800 for everything in this picture and parts 6 and 15 from the 2nd picture I'm posting. Parts 6 and 15 is for the saw to pivot on. Price also includes 20" harvester bar and chain. Only thing I forgot to ask the guy is for the lubricating part so will ring tomorrow.

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 ?

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?

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?

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.

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

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

I'm at kirkby Stephen. Can take any size wagon here. I'm wanting it to be delivered as well, forgot to mention that

I'm after 3 meter lengths ideally and felled as long as possible. If not Cumbria then can't be far away

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.

Largest it will do is 22inch but that can be made bigger if I had to. You can't really compare it to anything else because there's nothing else on the market that cuts and splits 5 foot logs. Next plan is the bundler which will be like most the others and have a ram attached to a wire that pulls the bundle tight then wrap baler twine round it which I have any amount of then release ram and roll bundle out. Will hopefully have bundler as a stand alone machine that plugs into a spool valve on the digger and will carry it round on pallet forks. The bundles are for my dragon D20 boiler which il load with a telehandler and bale cuddler grab. Ive yet to make a table for the split lengths to land on so we're not bending down all the time.

Forgot to say the log deck moves backwards and forwards and each time the logs moves along a notch and eventually get pushed onto cutting platform. Can get at least 10 ten foot logs on log deck and then the digger can stay still whilst cutting and splitting

The wheel on right side of the saw is one of the tracking motors, we welded teeth onto it so it can wheel the log along to chop at 5 feet. The wheel had double acting ram for up and down so we can clamp log down before we saw it

Since these pictures we have put a 4 way axe on

4 way axe lifts up and down so I can split in half or 4 ways

Here it is

or possibly the tank breather is blocked, what is the current back pressure in the return line?

 

or fit a free flow return straight back to the tank

I'm not sure what the last back pressure reading was but the guy that did was happy it was low enough. We fitted an inch free flow return pipe straight back to the tank to solve the back pressure issue

I believe I said this before

 

Your flow and pressure are more than the saw can handle by a substantial factor, it should have been the first thing you upgraded

Forgot to mention we limited the pressure to 2000psi and the flow to 40lpm for the saw before we tried running it after putting new seals in

I got hold of a pressure and flow tester and put it on the saw pipes and we found there was 1000 pounds of back pressure so we put a larger pipe on the return line and got rid of most the back pressure. I also got new seals put in the motor of the saw but when we tried it again today the seal immediately popped out so we decided to give up with the saw because it's starting to cost me a lot and it's obviously got other issues with it. When we tested the hydraulics we had 70 litre/minute of flow and 2300 psi so I think I've enough to run a hydraulic saw I just need to find one. I have someone currently pricing the parts for a saw up so fingers crossed its not silly money and I can finally have my processor working

I've tried the buckrake idea and it didn't work. It would push off that fast that it bent some of it because the wood was heavier than what it was designed to push. Got myself one of these now to lift my bundles in with once we get the bundler built

For example would the bottom blade do the job?

Proforge 250 Standard Single Bevel Wear Strip

Another question...... Do any manufacturers use hardox steel for there splitting axes? Guy building mine is redoing the axe and said he was going to use hardox again and it took ages to grind the sharp edges on the blades so I thought about buying a loading shovel bucket blade and cut it to the lengths we need, that way the edge is already on it!

You have 2 options, many hydraulic saws lube the chain by means of a case drain, this would need a relatively simple amount of engineering.

 

The second option would be to fit a small tank and feed the oil through gravity

 

My preference would probably be for the latter

Yeh I was thinking the latter also. Is there a danzco saw dealer in the uk?
