I have been selling the Norvise System for many years and I do 90% of my own tying on this vise.So I keep gathering information on its function, and I keep checking on ways to improve it. I do like Norm and his ideas but still, there is room for improvement, as you may see on my first blog on tuning the Nor-vise.
.

The problem I´d like to address today concerns the rear brass cylinder, the one that is not carrying the head of the vise. Several customers have informed me of the following problem: While turning, the cylinder moves toward the ratchet, gives off a nasty sound and rapidly slows down the spinning head. Or, even worse in my opinion, the head is locked, you are working on your fly, when all of a sudden the ratchet comes loose, and the weight of your bobbin unwinds your pattern.

Both situations are altogether unwelcome. Experiments with wax applied on the axle solved the problem temporarily. They only lasted about a week, and the wax makes shifting the brass cylinder by hand more difficult. A good solution has to be different.

Before listing the steps necessary to make the conversion, let me tell you the prerequisites. You should have experience with mechanics. You will need a lathe and know well how to operate it, and all drilling needs to be very precise!
.
This leaves you with two options: either you have the necessary tools and know how or you have a friend who does, or you can let us handle your conversion

Here´s the steps you have to take. Remove front and rear brass cylinders and the axle. Put the axle into your lathe and make two cylindric grooves in the right place and with the right distance. NB: this distance is just a few mm! The grooves shouldn´t be too deep either!
Next, drill a hole into the brass part and then cut a #4 (metric!) thread. Into this thread you screw (just a little ways) a thrust piece with a spring-mounted tip. Mount your axle into the vise again, and mount the two brass cylinders on the axle again. Now adjust your thrust piece in a way permitting you to move your rear brass cylinder back and forth without using a lot of force. If you have done everything right, the cylinder clicks into position in both front and back position.

With this conversion you´ll have even more fun tying your own flies with your Norvise.
Take note that I advise that profound knowledge in using a lathe and in precision drilling are absolutely indispensable for this conversion. I will assume no liability whatsoever for this conversion unless it has been executed in our workshop.
