  1. I've got some missing/damaged rubber slats on my lift conveyor off the processor. 2 or 3 are missing and another 2 or 3 are coming loose. The fitted ones are rubber and bonded to the main flat band of the conveyor belt itself. Clearly not man enough for the job. I was thinking of just using L shaped aluminium and using a dome headed bolt (coachbolt or similar) from the underside of the main belt and up through the L shape. This will mean that the dome head of the bolt will be running on the steel bed of the conveyor housing and also over the two main rubber rollers at each end of the conveyor belt when its running. I can't believe that this will cause any damage to the drive or the conveyor bed? Someone else must have either already done this or got a better plan? The only other way I can see of doing it is getting some rubber mat, same as conveyor belt, cutting a 6" long/same width of conveyor, attaching the L shape with the dome bolts to the "patch" and then bonding the patch to the main belt. This removes the issue with the bolts running on the bed or over the rollers, but the patch is on the outside of the belt as it curves over the rollers so that might come unstuck over time? Im inclined to go with the direct attach of the L to the belt? Any experience on this anywhere? Cheers Steve
  2. Yes somebody else has said that to me. We get through tier one anyway on drying wood so it is almost not worth the time/money/effort so I don’t think we will. Far easier just to put a log burner in there.
  3. The frontage is as long as we could make it. Took the longest 6 poles for the roof, then put a pitch in from the front to the back. Thats a 40' shipping container to the right and the barn goes back about another 2m so its about 14m deep, about 5m frontage. Cost me about £2k all in I reckon and most of that was the roof sheets. I could have done it for less but didn't want 2nd hand sheets
  4. I'm looking for a back up processor, needs to be PTO driven unless it has its own diesel engine, and was scrolling through ebay looking at various second hand models. Came across this, http://www.ebay.co.uk/itm/Lumag-SSA400Z-PTO-Firewood-Processor-GREAT-PRICE-GREAT-QUALITY/173015394708?hash=item2848856994:g:tnkAAOSwVgtZu7N8 seems incredibly cheap, so I assumed China, but its actually German! Vorsprung Durk Technik then!! Anyone have any knowledge of them? Cheers Steve
  5. We didnt faff about with purlins lol. By the time the roof and the sides are all fixed its all locked up solid
  6. Exactly that. Except we used telegraph poles, we buy them second hand for about £15 each, 2 uprights, 1 as a cross beam, like a set of goalposts, 4 sets, 2m apart and tin roofing sheets 3m in length. Just overlap the sheets and fix to the poles. Huge barn, and high as well.
  7. Main business is a Golf Club, so I have 4/5 greenstaff who have time availability in the winter period. We also had about 6/8 tree surgeons who brought us their chip/logs. We used the chip for pathways, then sold the surplus as a biomass fuel in bulk. Decided to get our own biomass boiler to heat the clubhouse, but found out that burning the chip was too complicated, but one supplier said we could easily burn the woodpile of logs, which was handy as we used to just push them into a big pile each winter and set fire to them to get rid of them! I had looked at doing firewood years previously, but the thought of doing all the work today and getting paid in 2 years time was a bloody bad hobby! So we went to look at a Dragon Boiler, and saw one attached to a drying floor drying firewood. In the earlyish days of RHI as well, so we eventually bought the boiler and an accumulator and a 40' container kiln, got it all approved for RHI, we burn the hard to split stuff as fuel and split the easy stuff into firewood. Had to buy in a processor, I bought a Gandini Forest cut (but got an EU grant for 40% of it). So. I've not really got any staff costs as I was already paying people, already had most of the kit. the boiler and kiln and processor was a total investment of £60K, and the RHI income is about £21k a year. Been going 3 years now, so I've got my money back on that, 17 more years of RHI to go then! We sell about 1,000 barrow bags a year, although that's just growing year on year now. Biggest problem this year has been the mild weather into December, as the grass has still been growing and we have been spending 3.5 days a week keeping on top of the golf course and 1.5 days processing. It needs to be the other way around to keep up with demand!! Still haven't got around to laying the pipework to the clubhouse to heat that from the boiler either, although I'm now more inclined just to whack a woodburning stove in there instead, if I can source some firewood.....
  8. I'm not sure that having a sharpened blade pointing vertically is a very good idea! If you can do all that welding and post holes, then build the same frame as the youtube video! Any reasonable size hydraulic ram will work, you just need a long ram which gives you a long stroke to push a big log so that it splits completely. If you can lock down the teleporter there is no reason why it shouldn't work, on the boom extension, but a teleporter has multiple rams for the bucket tip and the boom lift. I think you run the risk of bending these if the log doesn't split/push straight. If the log starts to lift or twist then you are exerting huge forces in a direction you were not intending. Bending one of the other rams is a "king expensive mistake. I would be looking to get a single ram exactly as the video, fix it into place so it pushes square. The risk of bending that ram is still there to a point, but you only have to look at one ram whilst its working. If it goes off line you stop. An equation for you on calculating ram pressure. This gives you the force in PSI. I think you divide by 2000 and that gives you push pressure in tonnes. Pressure = force (in pounds)/Area (square inches) We describe pressure as: X amount of PSI, Example: A round rod 1 1/8 inches in diameter has about 1 square inch of surface if stood on one end. Pushing with a force of 10 lbs downward, we would be exerting a pressure of 10 lbs per square inch (10 PSI). Now suppose we exerted the same downward 10 lb force on a round rod with a diameter of .18 inches, now we have 400 PSI. Let’s do the math. A=R² x TT (Area of a circle in square inches equals: radius of the circle squared, times TT), TT=3.14. Example: 1 1/8 ÷ 2 = .562 x .562 x 3.14 = .99 or almost 1 sq. inch. Continuing with the rod which is about 3/16 in diameter, 3/16 =.188 ÷ 2 =.094 x .094 x 3.14 = .025 Square inches. Pounds ÷ Square Inches = PSI; in this case: 10 ÷ .025 = 400 PSI. Putting pressure to practical use: One of the simplest hydraulic systems is the common hydraulic car jack. It contains a reservoir, a pump, a linear actuator and a valve; it does not however contain a prime mover (a motor or engine), our arms and hands become the prime mover or power by which we “jack up our car.” Fig. 1 Reciprocating Pump How does this happen? You can see by the drawing (Fig. 1) that when we push the small 3/16″ plunger down we are creating 400 PSI of pressure under the linear actuator (piston and push rod). In the example above, we showed that a 1 1/8 piston has an area of about 1 square inch. One square inch x 400 PSI = 400 pounds of lift. Now push the 3/16″ plunger down with a force of 50 pounds and we have the capacity to lift a weight equal to 2,000 pounds. However, we must be patient with the process as the 3/16 inch plunger will not displace very much oil with each stroke and therefore many strokes are required to lift the weight up, but we are able to do so because of the mechanical advantage the jack provides for us.Volume is a function of area x distance traveled for linear actuators. Example: the area in square inches for the 3/16″ plunger is .025 sq. inches x 1/2″ of stroke, that equals .125 cubic inches of oil pumped per stroke of the jack handle. Our 3/16″ plunger is a fraction of the size of the 1 1/8″ piston in square inch area and therefore the piston will only move a fraction of the distance that the 3/16″ plunger strokes. Which explains why we must operate the jack handle fast and furious if we want to raise the car in a hurry.
  9. The problem with the teleporter and massive logs, is not the hydraulics but grip/gravity/friction. My teleporter, when you put it up against a solid object and extend the boom, it just pushes itself backwards as the boom extends. So you would have to park the teleporter with a solid object behind it and the log solidly fixed in front of it. Then the winner will be which solid object is more solid, or the teleporter will break! One of those three things will occur!
  10. might be interested in buying the diesel trakmet? what model is it, how old, how much? cheers
  11. Hairdryer, waste of time. Use a hot air paint stripper gun http://www.diy.com/departments/bosch-1600w-240v-hot-air-gun-phg-500-2/1172238_BQ.prd for example. Plenty of heat from that. put your paper and kindling and start logs in and ready, run the hot air gun for a minute at the flue entrance, then point it down at the paer so it catches light!! Close door, job done. I used to light my BBQ with one!!
  12. As a bit of additional info, my 195kW boiler heats a 10,000 litre accumulator and the kiln is set to run its fans when the water tank is between 50 and 80 degrees Centigrade. Once the kiln draws it dawn to under 50 degrees the fans shut off. In practice this means we can run the kiln pretty much 24 hours a day in the week. We load up the boiler at least once a day, occasionally twice and let it go out over the weekend, then clean it out on Monday before starting again. The kiln is a 40 shipping container. I can't see the point of a 20' you can't get enough wood in it to make it worthwhile surely? Based on the above, it usually takes us about 10 months to hit tier one upper limit. .
  13. You can't burn fencing waste as a fuel in a RHI funded boiler. You have to declare what the source of the fuel is. There are some small exemptions for small volumes of waste wood, but it still has to be clean. Treated pallets and treated fencing panels are not clean. The revenues received from an RHI funded kiln depend upon when it was approved. Tier one is 1326 hours @ the rated output of the boiler as a max. There are different rates depending upon how big the boiler is, the threshold was 200kW I think, so if you were under 200kW then it was a higher rate than than a 200kW+ boiler. From the post above, if those are current rates, then my tier one max would be 1326 x 195 x 2.96p which is £7,650 if I did it now. I wouldn't install one now at the current rates, the payback time is too great against the investment required at the outset.
  14. I'm interested in insulating mine. I've PM'd you about it...
  15. I've just taken the Snugtop off my Navara D40 (2005 Mk1) and its in decent nick. Currently on Ebay if you fancy it. No reserve, so its definitely going to sell. nissan navara d40 Mark 1 snug top | eBay
  16. I've not had it mapped or anything. That's what the mpg computer says and I don't think its wrong. It tells me I can do about 500 miles on a full tank and unless I go berserk its about right. I've got a pathfinder as well and that's doing about 27mpg. The navara is the oldest and maybe its a euro 5 engine not a euro 6 like the pathfinder is? It seems to me that the emissions criteria makes the engines less efficient at burning fuel, ie it uses more fuel but gets less mpg as well! Bloody mad.
  17. Agree it is 1m3 less the wheel arches. I get up to 6 barrow bags in mine, and Ive got a truckman top on it as well! Bags are 48x48x97 and we get 3 or 4 on their sides and two upright on the open tailgate! So that equates to about 1.4m bagged up. If I was to take the truckman top off, which I might do, then I'd easily get all 6 standing upright in there. Cracking vehicle. I've got one of the first ones sold, on a 05 plate with 142,000 on it now, all done by me. Had a heavy duty clutch put on under warranty and that's about it. I'll drive it til it dies then get another one. Currently getting 37 mpg!
  18. Income received from RHI subsidy is "outside the scope" of VAT and therefore the VAT element is zero. So, if you receive say £1,000 from RHI subsidy, it is receipts of £1,000 with No VAT. If she has been accounting for it as a gross income of £1,000 and declaring that it is effectively £833.34 + 20% VAT (£166.66) then you have been overpaying your VAT and you can reclaim that.
  19. I'm happy to supply my kiln dried logs as a BSL accredited product. I expected there to be a greater demand for it, but, at least where I am, there appears to be negligible requirement. I'm not fussed about the fees they represent a very small %age of overhead costs as effectively I'm paying £120 per annum to advertise my products on the BSL.
  20. That's how I calculate mine! I take the monthly increase in the RHI reading, say 24,000 kw, and use a benchmark of 4500kw per tonne of seasoned wood, which as I recall, I got from the forestry commission or similar info? So that equates to 5.34 tonnes of wood consumed.
  21. The original advice I was given to complete the quarterly returns, was that I simply told them what tonnage/m3 we consumed ourselves to power our RHI boiler and what tonnage/m3 of kiln dried we sold in the same period. As I didn't have to pay any fees etc, it was just a matter of calculating the figures and entering them in the form, it made no odds to me if it was BSL or non BSL, and they said the total we produced. Once it became a charge per tonnage/m3 I had a more vested interest in whether it was BSL/non BSL.
  22. I rang the BSL Helpline today as I have been intending to query something with them for a while, since they started the suggestion of charges. Firstly, I'm a producer/trader as I use my own seasoned logs in my own RHI biomass boiler. I only sell kiln dried, I don't sell seasoned at all. I'm a Small/Micro company, which means my annual fees will be £120 per annum. We haven't got to the tonnage sold start date yet, but in the last Sept/Oct/Nov period, I've sold just over 120m3 of kiln dried logs. I'm based in Bedfordshire and almost all of my customers have woodburning stoves. Now, it was bugging me that in the three years that I have been selling kiln dried, and I was accredited and on the BSL right from the start, I have only ever been asked for the BSL numbers to be on the invoice, because the purchaser was claiming Domestic RHI, ONCE. That customer bought a few loads from us, but he wanted greater bulk and cheaper price, so I haven't had an order from him this year. So, essentially, 99.9% of my customers have no interest in the BSL number, they just want kiln dried firewood for their woodburning stove. They don't claim DRHI. So I asked the BSL helpdesk, how I should be calculating the tonnage/m3 supplied, in terms of is it every scrap of firewood I sell, or do I only calculate to tonnage/m3 sold to people requiring the BSL number. Amazingly, I got the answer I wanted! If I sell my kiln dried firewood to customers who need a BSL accredited number, I have to declare that. If I sell my kiln dried firewood to the general public for use in their non RHI woodburners/open fires, I don't need to declare that and I don't pay any tonnage/m3 fees on that element. So, I'll have to pay the £120 a year registration fee so I can use my own seasoned in my own RHI boiler, but I'm unlikely to have any further charges for tonnage/m3.
  23. I can't see how it would work to be honest. I have my own kiln (40' shipping container) with a RHI Boiler to heat it. If someone brings me 40m3 (which is roughly what I get in the kiln (20 x 2m3 cages on wheels) somehow, the supplied wood has to be loaded into the cages (which is done when we process/split our own stuff). Then the cages have to be loaded by machine into the kiln. They are dried over a period of 7/10 days, so I've got a fuel cost of the boiler for that period. Once dried, I've got to unload the kiln with a machine, then empty the cages into bags. The amount of manual labour involved is far to high, so the cost to me ,before I add a profit margin on doing the work, would mean that the person who supplied the firewood to be dried in the first place, would have such a high cost just on my element, before they add the transport to and from my site, then the transport to their customer! 40m3 at a time is just too small scale to get any economies of scale. The imported kiln dried is being done on a massive scale, with substantially lower labour costs and substantially lower timber costs. In addition, the only time that I have spare capacity in my kiln, where I am drying wood faster than I'm selling it, is through the summer, so the person wanting the timber dried would have to be doing all of this out of season and paying for it to hold it in stock for later. In short, the transport, handling, fuel and labour costs on a small scale don't make it viable. If you took the suggestion to put the boiler/kiln onto a flatbed, and take it to the wood source rather than bring the wood to the kiln, either you have to offload the boiler and kiln at the destination, which then means it needs to be plumbed together and electric power attached, which is not a 5 minute job, or you try and manufacture the boiler/kiln to be permanently on the flatbed, so it is a complete and ready mobile unit. Now the kiln and boiler is about 1.2m off the ground and needs to be loaded unloaded and the boiler fuelled. Apart from that, I can easily see this working!!! LOL
  24. I've never said you do. It's just the way I do it as it makes business sense to me. However, big brands like Homebase selling the same "seasoned" Log taints the whole seasoned log industry. There is an expectation that they have applied due process and got a reasonable product. So if their stuff is wet then some people will taint all seasoned wood with that same brush.
