Working for the Commission for the first time
Big J replied to Big J's topic in Forestry and Woodland management
I've often been accused of having a crush on Scandinavia as a whole. The forests there are so different to here, and require so little maintenance in order to get a top notch crop. I love the little harvesters from Usewood - their combi machine (both a forwarder and a harvester) is brilliant, but at over £100k, well out of my price range. Our trees seem to grow quite stoutly compared to in Scandinavia too, so even in a first thinning, I think you'd soon come unstuck with a 22cm throat. -

Excellent post Frett. Very informative. -

There are a couple of harvester heads available for machines of that kind of size, but they will only take stems up to 22cm diameter. The issue is that the machine has no weight to counterbalance the weight of the tree. That's why I went for the bed processor instead of a harvester type machine. It'll take about 37cm, instead of 22cm. We did cut quite a lot of nice 3.7m log out of it too -

Very true. In the scheme of things, the site we were on wasn't too bad, but it's just all so unfriendly towards smaller machinery. What also struck me was the level of wastage in the stands. We were working in a 48 year old block of sitka (the machine will lift anything in that stand at 3.1m, for reference) and whilst some effort had been made to thin a little, the last majority of the stand had seen one rack thin in it's entire history. As such, around 50-70% of the standing stems were dead, and due to the fact that everything was overdrawn, much of it was blown. Is it that uneconomical to thin sitka that it just doesn't get done? Assuming that the first thin could have been done at 18 years, if should be on it's 7th thin by now. I was just amazed how much dead (and given it's sold on the tonne, relatively valueless) timber there was. -
My ideal temperature does depend on humidity. Higher RH, lower temp. So usually 21c is OK in summer, but I like 23c in winter. For me, the threshold for fire is a sustained living room temperature under 20c.

The chap at the Commission was great about it. We came to the mutual conclusion that we tried, but FCS sites in South West Scotland are harsh on small machines. Just up the hill they are doing rack thinning with the chainsaw courses and with it being second rotation, the mounding and stumps from the first rotation means you need 75cm of ground clearance to get over some of them. The seat is good. Cab space was extended 5cm up and 5cm in length for me, but is still a bit too small. OK on reasonably smooth sites, but a bit jarring on heavy rutting. I'm hoping that the low impact nature of the machine is going to be my unique selling point. The National Trust for England have an 800 acre wood about 5 miles from here on a big country estate. I'll be calling them in the morning -
.....and the fire is back on again. We only made 18c here today in East Devon after a 13c night, and with a decent breeze all day the fire has to go on in order to maintain the wearing of shorts.

If you need more elm, Andrew and Ross at my old sawmill have loads (at least 50 tonnes) in stock in the round.

Ours is on. Didn't expect it in Devon in August, but the whole country is pretty chilly at the moment.

Soft / Hardwood roundwood Devon/Cornwall - WANTED
Big J replied to arboriculturist's topic in Firewood forum
If anyone finds stands of smaller timber (softwood preferred) that they want harvested economically and ecologically, get in touch. With my mini forwarder and processor, I've a good angle for getting into more delicate sites. Land owners can sometimes be fearful of the mess created by forestry work and the low impact nature of my machines can help allay that. -
Biomass and 3.7m log would be the way I'd go. Depending on the size of the timber and overall volume, I'd be tempted to just biomass the lot. I should add that I am very well set up for thinning sitka economically and with a minimal environmental footprint. I have a mini forwarder and a mini stroke processor, so I'd be keen to have a look at the job for you and offer some idea of costs and potential profit. I'm at Cullompton now (previously Edinburgh).

Most useful foreign language to learn?
Big J replied to Treesparrow's topic in International Arborist Forum
I would say that if you are intending to use it for work, then learn German. It's a country that places great value on quality tree work, with stunning forests and well maintained urban trees. You can also work in Austria and parts of Switzerland with German too. -

Got two new trainees on the forwarder: -

Well, the job is finished and there was good and bad. The main issue is that it rained each and every day for 2 weeks. The ground conditions went from passable to absolutely awful. It meant that we couldn't get the larch out through the soft extraction route that we were there to process. So in the end, we cut about 130 tonnes of larch which was left in the stand until the remaining spruce is clearfelled in three years time. There is no other way of getting it out. We also cut 175 tonnes of spruce (some selective thinning, some windblow processing) which I was able to extract. The forwarder performed well but I lost a few days to repairs. The leg assembly (which is now updated and improved with the manufacturer) was weak, and bent quickly. I now have a very strong leg system. Lost two days to that. The pins were also in need of bracing, which has now been done and they are now unbendable. I also had a very heavy log slip the grab and land squarely on the back left pin, which badly bent the cross member. Bent back and reinforced, it's much stronger now. Some of the issues were operator error (only got my FMOCS ticket last Monday) and some were weak points on the machine. What is good though is that the manufacturer is extremely receptive to all feedback and the improvements I'm making to the machine are being taken onboard for future machines. With my forwarder being machine 16 and the first into the UK, it's not quite a prototype, but it's not far off that. UK forestry is harsh compared to the lovely flat sites, and smaller, striaghter trees they have in Scandinavia. Anyway, we reached the conclusion that the forwarder isn't really suitable for Commission sites (on the whole) as the ground conditions are so poor. Huge dtiches, mounds and very high stumps from previous mechanical thinning. It's good to know what you can and can't do -

Fair point, and I'm sure that the job looked very smart when done. -

It's a shame, but it's just going for chip. It's been down long enough that whilst it's still heavy (sat on wet ground), it's starting to get blue stain running through some of it. Running the risk of rejection from the sawmills, chipwood it is. I'm not sure that the Commission would be happy with that with the machine having a 20m risk zone. I'm trying to avoid doing anything to piss them off! It's a good method though and one I'll keep in mind for other sites. -

I hate seeing stumps like that, but as you know, a lower cut would mean a full sharpen on every tree. What is annoying is that some of the stumps from the previous thinnings (all mechanically done) are actually too tall for my machine with 40cm of clearance to drive over. No need for it at all. Hoping to get another 250 tonnes out next week. Getting into the swing of it, the machine is working well and I'm enjoying myself. -

Big J replied to Big J's topic in Forestry and Woodland management
Haha! The stumps could be a bit lower, but they are all self righted windblow stumps. Until they were severed, they were all deep in the ground (it's quite boggy) and there was no way to cut lower without mullering the edge on the saw. I'm keener for my cutters to stay safe on multiple windblow rather than taking more risks trying to get a super low stump. -
I don't understand why on this windy, wet little island that we don't take greater advantage of what is widely abundant - wind and hydro power. I have no problem with looking at wind farms, and much prefer it to the unsustainable rate of timber felling at the moment. Scotland is incredibly wet, with vast amounts of rainfall on the west coast. Plenty of potential there as well. Producing 'green' energy from wood on a large scale is labour intensive compared to wind or hydro, which require no fuel to be brought to the generator. Wood is ideally suited to small scale, domestic and small business heating needs, and given the lack of supply in the UK, using it for anything else isn't sustainable.

Ended up on some fairly large spruce windblow for a while and the machine didn't struggle with anything at 3m. The grab on it is 0.16m square, which I presume means that when the grab is just closed the area is 0.16m. On this log, the grab is nowhere near closed and it's the small end of the log. Probably about 0.75 cube, and not the largest log at all. It's handling the terrain well, and it's very soft in places as well as stumpy. It's got the agility to wiggle between the various obstacles. -
Spot on. If you want someone to blame for the imminent collapse of domestic firewood, blame the government. RHI, paid by the government, means that anyone using wood who does not qualify for RHI payments is at an automatic financial disadvantage. Given the generosity of RHI, it's a huge disadvantage. Look at it from the sawmill's perspective too - chipwood is making more than green log now in places too. It's going to rip the heart out of that industry too. It's staggeringly short sighted to think that the UK has sufficient timber stocks to cope with the demand from RHI. If the UK leaves the EU without a deal, we'll be doubly stuffed with the issues it would create for imports.

Thanks for all the pointers chaps. Much appreciated. The first week went very well. The harvesting manager at the Commission couldn't have been more helpful and just left us to it. As we don't have the tickets for the processor yet, it limited our work a bit, so he found us other work to do to keep us going. Also not helped by having 4 inches of rain in 7 days softening everything and not having the tracks until next week. The forwarder is working really well too, and by Friday I was pulling out 5-6 tonnes an hour (on stack measure). -
what to do with lanky trees
Big J replied to westphalian's topic in Forestry and Woodland management
I'd leave some of the softwood in place. Mark out your desired trees and halo thin, but leave a ring of sheltering trees around it. I'd really try to avoid lopping and topping the trees as I can't see them having a long future. -

Big J replied to westphalian's topic in Forestry and Woodland management
I would say that the hardwoods there are too drawn to survive without the support of the softwoods. Topping them would be very labour intensive and wouldn't look good. Consider a mixed thin, leaving some of the softwood? -
Having just moved to Devon, I've cut off my firewood supply (no longer having a sawmill) until I get going with forestry down here. I'm sorted for this winter, having brought 23 cube of logs with me in a shipping container from Scotland. I would however like to get sorted for next winter. Does anyone have any jobs in the vicinity of Cullompton that will produce a reasonable amount of firewood? I can extract it for you with my forwarder (max lift 1000kg) against the cost of the timber. I'm not fussed what it is - I'll burn anything and my stove will take a 2ft log. I need about 12 tonnes for winter 2019 - 2020 No hurry either, as I'm completely sorted for this winter, but I'd like to get something in before the end of summer as it's easiest for the wagon to go through the field to offload. Not critical though as I can double handle with the forwarder. Nothing oversized though as I'm unable to move it, so maximum 2ft diameter. To stress, I'm not bothered what the species is at all.
