Thanks Ray, much appreciated.
I have got spacer fitted to the main pivot shaft now.

and also spaced the motor back by 1 nut width, which gives clearance when vertical.
While I had the motor off, I replaced the two bolts that the motor pivots on with a length of all-thread, which has made the motor mount very rigid now, ...it used to be very floppy before.

Ray, does your vice deck stop short of the blade by 30mm (ish) or is it closer, and also, does your saw provide any support for work-pieces beyond the blade? (see my pics above in previous post)

Hi Phill,
That is one big gap ! I would be making a steel block to go under the blade and as wide as the vise. I would screw it through the base to secure it. Without support at that point from the vise bottom to a little beyond the blade, you cannot cut a thin slice. I extended the vice jaws right up to the blade. Within a few mm. But make sure that the blade is cutting straight first. If the blade starts to run off it will catch the edge of the new jaw plates. An early warning system that the bade pressure is too heavy or is wearing out.Best Regards:

Just read this and had a quick look at mine.
Mine is 4 or years old,

The blade on mine is 25mm from the moving jaw of the vice (over as far as the as supplied slot allows) and 18mm from the fixed jaw.
I notice that your pivot shaft is a hair below the surface of the casting with the spacer in place - that is very slightly proud on mine so you might have lost a few mm with the thickness of that spacer?
My normal mode of use is for cutting pipe & bar stock but have had to muck around holding smaller bits on occasion.
Mine is exactly as yours with no outboard underneath support.
On a positive note, I did as you and checked the guide bearing adjustment pretty carefully and for my backyard hobby use it is streets ahead of of what I used to do with a hacksaw.Last edited by Ray-s; 17th Feb 2020 at 12:06 AM. Reason: spelling typo

I have just finished cutting the flat bar for the extended jaws, and happy to say that the cuts are dead square and straight as an arrow
Very poor design in not having any form of outboard support. I will have to fashion one to attach to the base casting a.s.a.p.
Is there any way to knurl faces of the extended jaws something like a set of vice jaws, or is not necessary?

Hi Phill, Bob, Guys,
I wouldn't bother trying to pattern the vise jaws. Mine are smooth ! If any friction was needed a piece of emery cloth placed between the work piece and the fixed jaw would work.
From looking at the pictures of the hinge in the various posts from different machines, there seems to be a wide variation in hinge widths ! Poor design, poor manufacture, poor quality control as has been alluded to.
Whilst when I bought mine, I knew from the outset that it required work doing on it, the multitude of modifications required to actually get a machine that worked properly as intended was unexpected.Best Regards:

The issue of a total lack of "outboard" support on this particular bandsaw design has now been addressed.
Length of 50mm X 10mm flat bar, two 30mm lengths of M6 high tensile all-thread, and 4 nuts.
