    That's all we fit now. When you have long tunnel (40 to 50 Metres )end vents don't do much unless its on a good slope. I have a couple of lads who have the hang of doing it. I believe they start at one end, one clipping on to the tube and the other keeping the poly straight and taut. Keeping every thing straight and square helps. I appreciate the expense thing but it would give you better temperature and humidity control as the seasons change. If you change your mind I will ask them for some hints. I presume you know about bracing the end hoops and not putting the polythene on upside down.

    What vents have you planned Have you straight sides, if so there are some neat roll up systems
  3. cornish wood burner
    If you havn't already done it lay a water pipe to the centre of the tunnel so you can have a tap there.

    Agreed. I've made up an extension lead with 2.5mm cable for my pressure washer which is 2.9 kw. Shorter the better though. Volt drop = more current= more heat= shorter life
  5. cornish wood burner
    It would take a lot of air flow to move much heat. Too breezy in your lounge then I would think. Back boiler in your existing fire heating your hot water and a rad ? Or go bigger but as you say more money.
  6. cornish wood burner
    So will the cable be 8 mm all the way? Remember the heavier the load the more sag you need otherwise the tension will be too high. If you are a featherweight then at least 3M of sag to keep within the SWL( assuming 8 mm cable. Do not tension then put a heavy weight on it. Other way around to give you a guide of the tension. Most IMPORTANT have someone looking on ready to scrape you off a tree or pick up the pieces if the tirfor or cable breaks.

    Regarding the pressure it depends what you are splitting. Most of my wood has knots in so I find I often need 8 tonne. 300mm ash normally just needs 4 tonne. Sounds like you have decided vertical, I think both have advantages. I have a horizontal splitter, down side is a 2 ft ring is heavy to lift on, up side is you are loading, turning and taking off without bending. Still picking up from the ground unless its from the trailer. Not sure which is best but I am happy with mine.

    Have either a two speed facility . I find that really usefull. It certainly speeds things up especially when you don't need full power or travelling up to the log. Look at the machine weights, that will give you an idea of the strength of the build. Spring return is good. Returns while you reach for the next log. Return stop to reduce stroke when not needed

    I think I will need to get a piece of 441/444. Needs to be about 500mm x 400mm x 8 mm thick. The grate is sectioned into different areas ,and that supports a short section.Total furnace grate area is close to 1.4M x 1.8M. ( 4'8" x 6') Thanks anyway
  10. cornish wood burner
    Thanks but I suspect it might be a bit small. Our boiler is 1 MW. What size is your Charnwood

    Hi Alec I did a spend a little time researching this afternoon and having two grades to look at really helped. Very relieved about the expansion on the ferritics and the cost can do no harm either. Absolutely top notch advice and information, thank you very much.
  12. cornish wood burner
    Not that it matters but I believe 50 M of 6 mm is only 7kg. Also only a proportion of that needs adding into our calculations. When we get to the heavier cable then obviously it will be more significant.
  13. cornish wood burner
    Agreed its 738 for 50 kg My mistake I never included wire weight. I presume 9kg is a proportion of the total cable weight. As you say bit much for 6mm.
  14. cornish wood burner
    Here's the start of an idea for you guys to think about. If you need the run your logs down hill it is going to take time to retrieve the pulley. So have two lines, then when a log is sent down line one it pulls the retrieval rope of line two pulley around a pulley to bring it to the top.
  15. cornish wood burner
    I make it 625 to lift 50kg. Remember the tension provides lift from both directions.
  16. cornish wood burner
    Thanks I will do a bit of searching. Problem is I don't know what the boiler manufacturer used originally. Would be good to upgrade slightly. Might bite the bullet and try a bit of 441 as Alec suggested
  17. cornish wood burner
    Thanks Alec I was tempted with stainless. Possibly overkill but do it once and all that. The only thing that I am hesitant on is the coefficient of expansion. It will be part of a retort and quite severely constrained so if it expands more than the original then might give a distortion problem. I don't carry the figures in my head but I seem to remember from long ago that some stainless can expand quicker than lesser steels. I will need to research this.

    My special steel supplier has now been taken over and head office didn't offer any suggestions. I don't think Bristol offices are very interested in Cornwall. Probably 8x4 sheets would be the only option for boiler plate. Thickness is limited by the slot in the grates unfortunately.
  19. cornish wood burner
    The steel or cast debate has reminded me that I need to source some steel plate to repair our large chip wood burner. The problem is the plate that supports the cast grates is corroded and buckled. Would the plate from a good quality stove manufacturer survive and would they sell me a piece assuming it would be good enough. It would run cooler than the cast grate but Im sure it needs to be better than mild steel.

    He doesn't have much idea about where to position a trailer axle for off road.
  21. cornish wood burner
    Yes high grade steel is tougher, stronger and will stand shock loads better.However at high temperatures found in a stove cast iron expands less, corrodes less and as TGB said is more stable and should not distort.
  22. cornish wood burner
    Grate in my Rayburn is 60 years old as are all the other cast iron bits. Still fine. I would be very surprised if any of the special steels that possibly are used in the better stoves would last that long.

    I used to think they had to have your agreement to keep your details but I think some companies seem to do it automatically. The AA caught me once as I had gone elsewhere and I thought the envelope just contained another one of their multitude of circulars. Turned out they just renewed my cover so I had double cover

    Council Tips/ recycling centres around here are more fussy. Had my 5ft 11 3/4 measured a few times. Only domestic waste but they seemed disappointed when it just complied. There was talk about banning trailers at their tips completely. Wouldn't dare take my 8 ft there.

    Hi scbk I was wondering if you have you a cunning plan to retrieve your nice new tandem pulley up the slope or just rely on pulling it with your retrieval rope by hand.
