This is a less expensive take on a rail bar system for a chainsaw sawmill rig. I have an Alaskan 24?guidebar on a Stihl 362.
Cons: The instructions for this kit are pictures only. You follow the picture guide and then figure it out from there. The spikes on the anchor wings that mount the rail to the log, and the plates that tie the sections of rail together will bend rather easily, and there is no explanation for what appear to be additional spikes included with the package. Are they to be welded onto the stabilizer wings when the originals fail, or what?
The three sections of rail will flex at the joints, and they will rack, so don't expect perfectly strait lumber. That's what bandsaw mills are for.
Pros: this is a lightweight, less expensive, take-down rail system that you can take to the woods to slab and square up timber for rustic projects or finishing with a bandsaw lumber mill. The Alaskan mill slides easily on the rails, and you can get fairly straight cuts with some effort.
It is a fair value for my needs.
