Bandsaw frustration

[JPG]

A voice from the distant past!


A half century or so ago (pre Shopsmith, Inc.) ALL the spt tubes were straight!

Side to side alignment on the jointer was done by adjusting the alignment of the cutter head.

More recently acquired knowledge is to loosen the screws securing the end castings to the bench tubes and rotating the 'legs etc.' to achieve front to back alignment.

IMHO the off set tubes were an improvement for the jointer(and other spts that are driven from the idler shaft hub), but not an improvement for those driven by the upper shaft. I think they introduce too many new ways to mis-align.

Now the bandsaw needs the proper tubes(short ones are a potential 'problem').

P.S. the coupler was intended to allow slight mis-alignment. Yes Pennview zero mis-alignment is best!;)

Please explain "short ones" and "potential problem".

I have three eccentrics (old model with no spring action) and two of these are mounted on bandsaws. What sort of problem am I suppose to be experiencing.

The third eccentric is mounted on my jointer.

I was picking up on Wannabe's short tube comment. I doubt you have a problem since I am sure you are using the correct ones.

Obviously the jointer tubes are very short and using them on a band saw is ludicrous.

However the band saw tubes must be long enough to pass into the socket and set screw area far enough to be secure. The lower portion must be long enough to secure into the spt tube mounting holes and be clamped.

Now I have not checked out how many different spt tube types there are, but have observed they do differ

I am using what I believe to be the original, rigid, one piece eccentrics. The new eccentrics, that are currently offered in the catalog, are in my opinion problematic in that they are reported to be flexible. Wave in the breeze I think was the term used.

One might say that the rigid ones, mine, are also problematic in that with a bandsaw installed on these the headstock cannot be raised to vertical without removing the bandsaw.

I simply run the bandsaw elsewhere and have installed the jointer on the left end of the Mark V. This is its virtually permanent assignment.
