Quick update:
It’s arrived and I’ve tested it on a couple of trees over the last few weeks. I decided upon the Logosol Timberjig which is there very basic kit but you are able to purchase the additional items to build it up as required. The Timberjig comes flat packed but was very simple to build, there is a DVD that comes as well taking you through the assembly step by step. Once completed your chosen chainsaw is very quickly and easily installed onto the jig. This is one reason I preferred this product as the chainsaw installation is so simple and there is no need to drill or modify your chain bar in anyway. The only other thing you need to do is make up a guide rail for the first cuts.
So off I went to find that old piece of chestnut that had been lying around for some time. After a few minutes fixing the guide rail and check the chainsaw and jig I started the first cut, shortly later the second, third and fourth. Wow, it worked and worked well!
Since then I have changed my chain bar for a solid 0.050 gauge bar I had and got a ripping chain to suit, which doesn’t cut any faster but cleaner with less waste.
As Richard states the chain needs to be sharp and the bar needs to be solid construction with a minimum engine size of 50cc recommended. Chainsaw mill aren’t as efficient as a mobilesaw mill but with the results I have achieved so far after just a few weeks (and I’m sure my technique will improve) with both chestnut and oak I would highly recommend a chainsaw mill to anyone.
