I have built several of these over the years, and it will work, depending on how high you have to lift the log. A "hydraulic" top link really helps in keeping the forks level and is a big improvement when using them.
The Norwood Lumbermate bandmill can be set on, or close to the ground when milling, so the logs are easy to roll onto the log bunks. Norwood sells a cable winch for loading and turning the logs, and it works very good.
How big of logs are we talking about??
