I know some of you out there have experience of these things. I have just purchased a logosol timberjig It seems very good but slow if I was paying myself minimum wage I would be in a deficit position. So okay I am using a very cheap and nasty Chineese 24 inch saw with a standard chain, but it is going vroom so it is doing something. The question is would the purchase of a sexy new stihl 660 and a ripping chain be worthwhile or would I just be able to ponder the expense of it all as I wait for it to chew its way through the wood. My last attempt has been on some fresh felled Alder only about 9 inches cut. I have a big chunk of Ash to cut which is more like 20" and I am not sure whether there will be enough daylight hours between now and Christmas!
