Thread: Leg vise Parallel Guide Adjuster by Ancora Yacht Service

As a result, there is a little more resistance in the parallel guide moving back-and-forth compared to before. The chop still moves smoothly, and the effort is similar to that of the Record #52 1/2 I had on my old bench. Of course, this may just reflect the need for a little fine tuning since the parallel guide is new. As it stands, this is a rejuvenated vise, one that promises to work with a much greater range and considerably less effort.

Once Jim gives the OK I will post a pictorial of how I installed the kit.

Hi Derek, Since seeing the original post about the chain mechanism I have been thinking about using it in my shaker bench build. I may not fully understand the mechanism but would it be possible to run the chain in an open mortise along the top of the parallel guide and thus allow retention the rear roller guide? The sprocket in the photos is too wide for this but a narrow one with a larger circumference might be able to extend into the mortise. The roller guide would then have to be mounted further back (behind the sprocket) and would contact above the chain on the sides of the mortise. Hope that makes sense.

Those types of modifications are difficult ... and may be unnecessary.

In our discussions, I suggested something similar to Jim. He replied, "The way I understand the upper roller, it's function is taken over by the chain. The chain will not let the beam swing up past horizontal because then the jaws would be out of parallel".

I have a little more tuning to do, and will report back. Please note that my earlier comments were about the relative resistance when the roller was removed. With the roller (before the chain), I could spin the screw in effortlessly. It would continue to rotate on its own momentum. Now, with the chain in place, the momentum is no longer there. Nevertheless, the screw turns easily.

Thanks Derek. Hadn't thought of the chain acting to stop the parallel guide kicking up. Will continue reading with interest.
