The tires are narrower than the wheels.

The wheels do have play in the bearings.

Since the blade is not dependent upon the wheels for alignment/tracking, the wobble is not terribly worrisome.

Do realize this design is different from most if not all other bandsaws.

If you have not yet noticed, the outer rim is beveled(the outboard side is larger than the inboard side.

The blade does not track like a typical bandsaw because of that.

The blade is guided onto the upper wheel by the rear guide bearing as it approaches the wheel.

The blade is similarly guided onto the lower wheel by the lower guide bearing.

The upper wheel is canted so as to force the blade into the rear guide bearing.(i.e. the wheels are NOT 'coplaner').

This results in the blade 'leaning' back at the top relative to vertical.

I mention these 'details' so you will not be concerned when you 'discover' them.;)

I am, surprised at your comment re adjustments being 'easy'. There is one that is a real PITA.


I am posting this as is, but will come back and add a link to MHO on how it should be 'adjusted'.

New bandsaw tires

Post by brianj »

Thank you! I will refer back to your post when in need. Regarding my comment about ease of adjustment; in comparison to other saws that use flat wheels, and require coplaner adjustment of the wheels; with fine adjustments made behind the upper wheel (removal of the wheel) with four tiny set screws, and adjustment of tilt with a screw at the rear, and aditional crowning of the bandsaw tires to achieve proper tracking; I'll take whatever the shopsmith saw throws me over the others. I have a 1/3 horse 8" central machinery bandsaw I never did succeed in getting the blade to stay on and track right; talk about losing your religion! That thing is residing in the attic to this day; until I conjour up a truckload of patience to mess with it again, so I can sell the darn thing. So far my only major issue with anything SS is the inability to readily get parts, or get individual pieces that would make repairs cheaper for people like me on fixed incomes; that really anyone with any mechanical aptitude, and a shop press can do.
