  1. Oh joy. I wouldn't be buying anything from that site.
  2. Yes I knew that, previously they could have a 5 shot magazine now it has to be blocked to only hold two but you can load another once you cock one into the chamber. Browning designed one in 1904 which stayed in service into the Vietnam war. My point was I had not realised self loading rifles were still allowed, I thought they were banned after newbury.
  3. I heard about banning lead shot, semi auto shotguns have been banned for over 30 years I thought, never had a FAC so didn't realise you could still have self loading rifles. What is the difference in striking power of steel verses lead shot, give me some figures? I have never shot steel or tungsten. Steel shot in a plaswad won't affect the barrel, plaswads should be compostable in any case IMO.
  4. What do you expect from the hospice shop? Now where can I get trousers NATO size 80/88/104 that aren't camo so I can wear something comfortable to work?
  5. Yes, just expanding on it really. We can have an argument about something else:001_tongue:
  6. If it weren't for the LEZ those transits would be my choice for short hauls, easy and cheap to fix. Modern 2.2 TDCI look like they will get expensive to keep past 100k miles.
  7. Higher auto ignition temperature would mean it was more difficult to start, do common rail diesels inject more advance of TDC? Detonation is what Rudolph sought to eliminate, he was looking for a smooth burn during the power stroke without knocking. Although of course you want the burn to complete as soon after injection as possible in order for the expansion to take place from the highest pressure. In the old days of slow diesels the aim of the injection was for the burn to take place at constant pressure whereas the burn of a spark ignition engine was aimed at expanding from a constant volume. With modern diesels, especially common rail,the injection is faster, more fine and precise so the diesel has moved toward the burn at constant volume whilst retaining the high volumetric efficiency of not throttling the air supply.
  8. Denseness is related to the carbon content, so petrol is less dense than diesel. As they both have about the same calorific value per kg and petrol has about 90% of the calorific value of diesel per litre I would expect the less dense fuel to produce less heat per litre and less miles per gallon.
  9. Mine seems to get better with age I spent about 100,000 miles getting around 63 mpg but now it has 288k miles on the clock and newish tyres my last tank gave 72mpg. I mostly commute 40 miles each way much of it on motorway where I seldom get the chance to get over 65mph. It's a 1.4 tdi in a pug 206. Guys at work with the same engine in fiestas struggle to get 45mpg.
  10. Me too mice I tolerate in the garden but trap them if they get in the house, rats I don't want anywhere near me. Woodmice can be a problem though, one ate through the wiring on the county, took me ages to find the break behind the instrument panel.
  11. OK that's not too bad, I misinterpreted the meaning of 20% duty cycle which was in the advert.
  12. As far as I can tell the saw was all original, cylinder definitely Stihl, 2 years old. As I said earlier in the thread it suffered from chronic over reving before it seized. The piston could have suffered then but it didn't seem damaged. It was resembled with the original gasket and the big chunk is from a section of the piston that cannot strike the crank. I'm trying the golf piston from sawbits.
  13. Even the duty cycle on the Ring one is 20% so probably 5 minutes on and then 20 minutes off. I found the cheap ones ok for car tyres, if short-lived as they have no lubrication. Not much cop at popping the bead back on a 13x34 tyre. Over the years I tried many things, when I had a petrol landrover the shraeder spar plug thingy was best. I even took the 150W compressor off an old fridge (naughty as this released freon into the atmosphere) and ran this of an inverter but you still needed to keep the engine running as 12A soon discharges the battery. If one could find a continuous duty 12V compressor and only wanted to buy one why not have that and an 8A battery charger whilst using it from mains. I have a scuba bottle, fully charged, which I inherited 6 years ago from an air rifle enthusiast. I was thinking about trying that to inflate tyres as it has a pressure reducer on it. I never have found out how much they cost to have refilled.
  14. Unfortunately I didn't get the chance to recheck it, chap said it rattled a bit and stopped. Plug was chocolate brown , so a bit rich if anything and the rings were good, so I pulled the cylinder and found this: Big chunk was long gone but I guess it caused the small piece to break away and it was this that was jammed between big end and crankcase. I wonder if the piston damage was related to my repair or what? I couldn't find a meteor piston so let's see how a golf one fits, stihl piston is over 70 quid and would be a better bet in a newer saw.
  15. I have one and it works but clogs up pretty quickly.
  16. Why not simply that the grip was poor, pushing part of saw cutting when it kicks back?
  17. Our fitter made me some of the spare wheel winders, they work with a ratchet spanner, I didn't think there was anything special about the scissor jack. PM me if you want one dropped over next week to try.
  18. It seems to work from firefox but only shows my home, I think it logs IPs you use to access a google account, so if your android is set to receive e-mail. I check the traffic before my journey home but it has not logged that.
  19. Bob this was a big problem in November 82, it was cold enough to affect steel at -18Cand I broke a gear lever at RMA Sandhurst. What was talked about then was the cold filter plugging point, this was when wax precipitated out of the diesel and after a few minutes blocked the filters. As you say the solution was to add petrol to keep the wax dissolved. It was worse on lorries because the salt used to melt the snow meant that the slush was actually well below freezing, so when it wetted the fuel lines and tank it made them colder than 0C, the subsequent evaporation made it colder still. After that the standard gasoil/DERV formulation was changed and I didn't think we had summer and winter grades after that.
  20. is that why it's not worth taking a shortcut through single track roads round there from Outwood and Horne? It's a faff having to reverse 300 metres to turn around and go the main road.
  21. I've dried them in the oven and an ash log out of the middle of my uncovered log stack at home. This last was interesting as it had only dried to 27.5%mc in the summer yet the one in my workshop in open air had got down to 14% in the same period, a good case for a loosely stacked and covered store. Anyway please see final graph below, it differs from the last one in that I have referred all the figures back to moisture content in %. You will note the slower drying in the wet bit of August and how moisture content has started rising in all but the oak and elm after October. The reason it doesn't quite match with my earlier offering is that the initial moisture contents were higher than I allowed for, I guestimated them from the FC mensuration handbook (39). This is not surprising as we all know from reading that lover of Norwegian folk music that moisture content varies with which part of the tree the wood came from but more importantly with the season, these logs were summer felled so one would expect the sap to be at its highest.
  22. Yes Joe has it right, I find depressing the bottom piece with my little finger and the back with the palm then opening the gate with my forefinger easier than the lift and twist then open of the other type.
  23. Yes my misreading, it is 27kN which means it could hold 2.5 tonnes. I thought there may be a problem with what you refer to as "snap gates" but why? We have much the same type of gate on the fall arrest harnesses used in MEWPS for building works, though they are much bigger and steel they have the same sort of lock on the gate. I cannot see how I'd use a double fisherman's knot, I use that for tying a loop, I was thinking figure of eight?
  24. Yes but the crab hasn't failed, its rope lanyard has. I was wanting to know if the type of gate lock was inappropriate for other use, It's rated at 2.7kN which means you could (just) hang 1/4 tonne from it. I get the job of destroying climbing kit that has failed LOLER and won't have a qualm about smashing it if it should not be reused
  25. Not that I intend to climb again but is it permissible to use the carabiner from a Stein strop that has failed LOLER because the rope was damaged for other climbing purposes or is the lock mechanism only for strops and not main rope duties?
