Also, when it comes to prep for the logs, do I want to seal the logs before i cut them, or cut them and then seal the ends? Or once cut, I don't need to seal since it will all dry evenly now? Thanks,
Joe
Welcome to the milling forum.
Plan on sealing the ends of the logs as soon as you buck them up from the tree to prevent end checking. The best product is anchorseal made by UC Coatings. This is very important with Ash as it tends to end check more than most other wood. Slather up ends good with coating and apply a 2nd coat if needed. If you trim the boards after milling coat the ends of those too. If you can't find end sealer latex paint is better than nothing.
I'm a little confused from your first post. Is the powerhead you are using a 460 or 660? Either one can be fitted with a HD oil pump which will help when using a long bar, or consider an auxillary oiler or water drip system. Don't worry about those to start out. Get your setup dialed in and get some practice. Might want to start with some low quality logs and just make up some pieces for rustic benches and such for practice. I wouldn't start with a veneer quality log.
Learning how to get the best lumber out of a log is a long process that starts with felling the tree. Lots to learn about between there and a finished board/beam. Read as much as you can about each step. It will help to watch an experienced sawyer open up a log and see how he goes about slicing it up and then how the flitches are processed into boards or beams. Once cut up you need to stack/store/dry the lumber. Watching how this is done you will learn a lot too. Might be some people who run portable mills or a small circle mill on your area?
You will find other various equipment/tools are handy/needed and make things go along more easily depending on what you already have.
Don't hesitate to ask questions. Above all be careful and safe.
