After looking at some images on google I reckon Rhagium mordax is the most likely candidate. Rhagium mordax - a longhorn beetle - Natural England I hope it goes on to lay some eggs in the decaying sapwood of the 4 foot stump we left.

:thumbup:I saw a sycamore stump with a yeast infection today and only new what it was because I had seen it here. Nice work.

I have been a bit quiet on the photo front this year. Glad you liked them. We always have a good quota of interesting work on. I will look up longhorn beetles and check it out. I managed to squeeze out of the window in the landy but it wasnt easy. Anything to reduce the drag. Handbag is Mats. I was really pleased with the reduction its probably one of the best I have done in a day. Is the decay in the Beech butt the Meripilus ?

One of my lace lock eyes has snapped and the stitching is coming out on the left boot heel. I think its where the spikes straps rub. From the wear on the soles I think they will last 12 months. They are also very cold in the snow. Great for climbing in but I think I will go back to Tiroll fighters next time.

Many photos from the last 3 months from my mobile.... Enjoy. 1. Unidentified bug found under the bark on a dead Oak. 2. Rigging the larger parts of a sycamore straight into the trailer:thumbup1: 3.

Good advice. Thanks.

The legs went off to a local oil hydraulics engineering firm and for the interest of anyone who may come across the same problem the diagnoses was.. Both of the rams cylinders had a bulge at the bottom. This was causing the seals to blow leaving the legs stuck out. They took the two of the best spare legs and fitted new seals.

The gold rings on the sequoia are fine to clip into. Petzl recommend it. The only issue is you have to clip into both, and the bridge must be present.

You have done a nice job its appears even but................................ I would have done it differently. I would have thinned out pretty much exclusively the outer crown targeting long branches that are pushing there way out of the desired shape of the tree. I feel this would have set the tree up better for future reductions that may be necessary to pacify residents and retain the tree. I think your right the tree didn't need thinning.

My current favorite way to descend on a single line is to use a single large cambium saver ring and crab like a stitch plate. I clip it to my bridge and my hitch climber and hitch stays on the swivel on my bridge. The swivel just lifts the HC far enough away from the ring stitch plate. I think this is what rock climbers call a rappel ring. I works very nicely. I was shown it the Cs41 course by the trainer. He was using a prussic above it. When doing this you should use a crab with a round profile.

Great photos. We had a real run of dead cedars in church yards. I think they die due to excessive burial severing large rooting areas. Its a real shame they are not managed better. Someone should produce a guidance note for burial under trees in churchyards and circulate it.

I found this inside a Ganoderma resinacium. I think its a fungi flea beetle. I did have a still image but I have misplaced it. I used my lidl microscope to look at it. The fruiting body was quite dry by the time this thing had moved in. fleabeetle.mp4

Thanks

Im back thinking about it again and I have been reading up about pilot operated check valves. It seems some are pressure sensitive and some not. I found this picture of the valve on the legs. Does anyone know if this kind of valve would be pressure sensitive ? Oil comes in the top pipe and out the one on the right. The balls cover holes that oil can flop down to the top of the ram, the bottom and back to the tank. the leaver moves the little pistons that push the balls.

What is the difference between a nitch and a notch ? I have tried putting cuts on some fruit tree trunks to encourage lower growth but never been back to check them.

It could be the offset blades that make the flywheel un-balanced.

Maybe thats why the bearings dont last as long as they maybe should. I could be remembering this incorrectly and giving out bad info.

True but to comply with the Health and Safety at Work act you must do all that is reasonably practical......... Its reasonable to ask someone to get certified. If something went wrong the HSE or courts would probably say the operator should have held the appropriate NPTC certificates. The legal issue is not complying with the Health and Safety at Work act. The HASAW act is really about protecting workers rights its not there to try to stop people earning or impose unnecessary red tape. It has changed industry for the better and probably saved many lives. A small proportion of companies, or individuals will never come close to fully complying.

Got to be in it to win it. One free ticket for me please

Im defiantly not an expert but heres my pennys worth....... We changed the bearings on one at work a few years ago and they went again really quickly. The bearings were not quite seated right. We then took it somewhere and they said some shims where missing. I think they went behind the bearing housing. There is a test to see if you have seated the bearings correctly. I think if you have all right when you spin the fly wheel by hand it should be so smooth that when it slows and stops it should come back a quater turn.

CHAPTER 10: Directional Control Valves, part 1 This seems to have the answer in it somewhere Im sure

Just "pilot operated check valve" and got this: The pilot operated checkvalve Im thinking you may be right. We have just been running the pto on tick over maybe there isn't enough pressure to open the valve.

Thanks for all your replies. Keep them coming. We lifted the trailer to remove the pressure from the rams and have disconnected them from the trailer to take the valves apart again. 2 pipes The diverter valves are piped straight to the the same pipe that supplies the main valve block for the crane. I think the diverter valve should work independently with out using the levers that control the crane. The diverter valve has four ball bearings in it. One is part of a one way valve that is on the pipe that supplies the pressure. The other 3 sit over the holes that the oil is to be diverted through. One hole leads to a galley that supplies the top of the ram, one to the bottom of the ram and one hole allows oil to flow back to the tank. The lever operates by opening one or 2 valves at a time to either extend lower or lock the ram. I think either the valves are opening out of sequence or one of the valves (the one that allows oil to flow back to the tank) is not being opened. I have a photo of the lever, pistons valves and springs on my phone. I will try and borrow a card reader to get it on here. I bet allot of you if you had it standing in front of you would be able to solve this very quickly. Thanks again for every bodies input. Breezeblock when I get a picture up of the insides of the diverter valve can you tell me if its a pilot operated check valve as I have no idea what one is. We dont have a manual for it so I have no idea what kind of pressure I should expect.

This could be the case but we have not got it to work yet. The legs are piped directly from the pump. The spool valve block is then attached to this pipe with a T joint.

Im good thanks Ben. Il drop you a pm when I get some time and find out what you've been up to. I gather from some of your other posts you've now gone self employed. Hope its going well for you. It confuses me when I look at it in front of me. Your right pictures are necessary. Another picture of the lever on top of the leg. And one of the trailer before it got stuck up in the air.
