Bandsaw Mill Build

The drive wheel is the bandwheel that will be powered.  The power will be transferred to the wheel through a pulley which attaches to the back side of the drive shaft.  Whereas the idle wheel was all about making it mobile, the drive wheel is all about making it rigid.
The next biggest things that need to be added are the drive wheel and motor to the beam.  Those items will make the beam much more difficult to manage should it need to be removed which it does in order to paint the carriage and to prep the beam for the raise/lower mechanism and the blade guides.  So instead of moving forward with the bigger items and kicking myself later, I decided to knock out some of the less glamorous items.
Now things get exciting.  The pretty boring steel structure starts getting mechanized and turned into a bandsaw.  The first thing to cross off of the list is the mount for the idle wheel.  The wheel needs to mount to the beam and be able to move away from the drive wheel to tension the blade.  It also needs to be able to tip and pivot to track the blade.
Before I keep adding to the carriage and saw head, I want to get the track painted.  The carriage has to be removed from the track so that the rails on the track frame can be removed to be painted.  The carriage will be able to be painted while it is on the track and I will paint the carriage after I'm further along with its construction.
Now that the skeleton of the carriage is built, I can start adding the saw head to it.  The beam that will support the wheels needs to be guided through it's up and down travel so I'm adding a center upright to the carriage to carry those guides.
With the track built, now we need something to run on it.  The carriage will hold the saw head and travel down the track.  This is just the basic carriage frame.  As we get into adding the saw head, many additions will be made.
Now that the frame is done, I can start adding stuff to it.  There is a pair of tracks that will guide the carriage and the cross members of the frame get capped with a piece of stainless square tube for the logs and cants to rest on.
Next up is the installation of the leveling nuts and then all of the frame parts can be laid out and welded.  Care needs to be taken when doing the welding so that the frame remains flat and does not distort.
Getting started on the frame that will support the logs and guide the carriage.  Before the frame can be welded holes need to be drilled and tapped to attach the stainless steel runners and holes need to be drilled on the underside to receive the leveling bolts. That's 54 5/16" holes and 27 15/16" holes. 
In this first video we look at some of the details of the mill and I set the stage for the series I'm doing on building a large cut width bandsaw mill.
