I use old hydraulic pipe with the metal fitting welded to a plate and bolted to exhaust, the pipe dos'nt get too hot so you can touch it without gloves.
Won't go again,the lurcher show was a long way behind schedule and very disorganised.I usually go to the Fell and Moorland, but fancied a change.Next year i'll be back to Richmond.
My current dog is very hard mouthed, but had a bed/collie/grey bitch that was hard on rats but would bring back rabbits without a mark and lick the ferrets
Only used the liquid type made for dogs, don't know that I would use cattle one myself. Can pick drontal up cheap enough on line and does a better job.
