Has anyone got the belt size for this chipper? Had it written down, but can't find it now:blushing: 222MS

We've just changed the flywheel bearings and reckon the cut out on the bearing housing is to undo the grub screws, freeing it from the shaft.

Had that in the past. Asked if they would have payed more if the job had gone over resolved the discussion.

Redwoods have been great today. Parts arrived at 9AM. Phoned the service department and spoke to simon re. the rollers. First thing he said to look at was the air gap on the speed sensor. With the flywheel/pulley assembly moving forward when the anvil went through the gap was excessive and the screen was showing 0RPM Re-set that - still not reading. Swapped the speed sensor with the hood one and the engine starts - so the sensor works. Swapped the wiring tails over to check them, they were ok. Spoke to simon several times to check that wires were correct etc, really patient, helpful fellow, but by mid afternoon it was looking like the electronic module was faulty. Simon still had a gut-feeling that it wasn't that but I think was running out of ideas. Decided to take the machine into O Plant at Liverpool next week after we sort the mechanical problems, Simon said it would be cheaper for us than arranging for someone to come to us. This evening our auto-electrician neighbour said he'd have a look. So we put all the sensors back to their original positions, started it and then pressed the P3 button to demonstrate the 0-RPM reading - which now read 450RPM. Turned the revs up, pressed the feed button and the rollers are running both ways. RESULT:thumbup: Not definite yet, but looks like a faulty connection on the inside of the box that got tweaked moving wires about, remaking the connection. So hopefully we can resolve that, put new blades in on monday to set the flywheel in the right position and all's sorted. Big thanks to all at Redwood, everyone I've spoke to has been really helpful, explaining how things operate or should operate, finding parts that they don't supply to the public and getting them out to us, and most importantly returning calls.

Interesting 'life belt' on an oak yesterday.

Bought it as a used machine and it's now out of warrenty. I think it's got around 900 hrs on it. We were looking at last night and it's a bit of an oddity from a design/manufacturing point of view. The flat bar looks as it sits in a little recess at the bottom, then has a short run of weld <10mm , it's then welded across the width at the top. I'd imagine that it's a high stress area and receives a lot of shock loads as timber meets the blades - so maybe it could have been designed or built stronger. I think we'll be adding a tad more weld when we replace it. I'm not too hopeful with the wiring, think when the roller jammed it's overloaded a circuit but would have thought a hydraulic pressure release valve would have prevented that

Just checked with mechanic cos I had to leave him for a bit. Definitely no power from one of the box outlets:sneaky2:

I know the wire you mean. We've swapped them over but which ever configuration they go on we only get feed one way. Seems there's no live feed on one of the two electric box outlets.

We've had a bit of an issue. The welded plate to which the side anvil is bolted sheared its weld and came adrift. Plate, anvil and bolts disappeared apart from a piece of the anvil that jammed the bottom roller. Freed that, pulled the bottom roller plate out to make sure nothing else was in there and thought that was that. Redwoods have found a spare plate for us to weld back and posted everything to us this afternoon. In the meantime we've test started it, only to find that the roller will only run in reverse. Swopped the electric feed wires to the hydraulic block and it will then only run forward and won't reverse. Had a look in the electrical box, all the fuses are good. Swopped the three relays - no change. Until I can speak to Redwoods in the morning, has anyone any suggestions/had similar problems? I've a horrible suspicion that the anvil piece jammed the roller and something electrical/electronic (and expensive) has burnt out under excessive load:sneaky2: Or could the forward/reverse buttons have gone south?

The the wood wide net:biggrin:

I've seen worse:sneaky2:

Wonder if he can do that with climbing ropes:blushing:

Had mine a couple of years. Struggles a bit to locate the tree base at times even with sparse vegetation and very occasionally with the top of the canopy. I had hoped to measure crown spreads, but it won't read unless you're more than 10m away. Not having used anything else I've nothing to compare it to.

Which area of cheshire?

Starting a site on monday at Bredbury, so does anyone know of anywhere to tip chip and timber locally? Cherry, Rowan, Whitebeam and cedar. All firewood, nothing worth milling:sneaky2:

That would make a nifty throw bag launcher.

Us too. Lightening for 2-3 hours. Initially the rain was tropical, putting down two inches outside our patio doors in half an hour. I think Manchester Fire service had over fifty odd calls for flooding.

Don't think your far wrong. An explanation I read did highlight those climatic circumstances as a precursor in a number of cases.

I'll download that when I get home Thank you

If a traffic officer has to google the answer, what chance have we got attempting to stay legal? FFS......

I've read a few papers on this, but never come across that. Was there any conclusion as to how the tree 'knows' there's moisture in there? It's accepted that roots will grow in the trenches where drains are installed- less compacted soil and moisture from condensation on the pipes exteriors, but I'm still surprised. Any links?

Only hypothesis' about tensile strengths and water content relationships, as far as I know.

Think you need to bend your knees more when lifting:biggrin:

More common in males, apparently.

Maybe the drains are in the wrong place and inadequately installed? Sorry eggs, bored today:biggrin:
