yes i bought them from market,for £16 each.they were 10-12kgs.cheap price cos they were over £50 last week.for the same size.i have today put the chips in with a little dampened water on them i have now timed the burn and i think i have about 4 hours smoking from one doughnut half ring sieve.devided by a little piece of foil so that the chips burn only one way round the ring,bellies now hanging in the garage waiting for the pelicle to form.tried some last night,fried and grilled streaky bacon.grilled was great as it seemed to release a lot of the salt from the fat on the bacon.yum yum,cant wait to smoke tomorrow,oak dampened chips for 4 hours in my metal office double door cabinet,i`ll do some pics to show how easy it is and cheap to do,i might do a ham next and some smoked haddock and salmon.good this smallholders web,colin
