It is a simple hand operated tool, one hand on the tool and the other on the bamboo below the female ferrule. Turning the rod (radial screws slightly tightened) works down the diameter of the female ferrule. Stay a little back from the welt and from the moisture plug. Twist several times, remove and test the fit. If still loose, repeat with slightly tighter screws.

The two radial screws will have to be a bit more than finger tight in order to achieve a shrink. They are #10-32 size, and require a 5/32 inch Allen wrench (not included).

You will probably need the skill of abrading a male ferrule to final fit, as it is easy to shrink the female a little too much.

As of September 2020, I have several in stock.

    FAQ

Q1. How is this different from crimping with a 3 jaw chuck?
A1. When crimping, you bring the material to the stress level that causes permanent deformation and you end up with a ferrule that is deliberately out-of-round. With this tool, it is my belief that the stress level that allows the diameter to be “spun” down is somewhat below permanent deformation and the ferrule is made more nearly round. I cannot prove this, but my before-and-after measurements indicate that roundness is improved.

Q2. Can this be used on a ferrule that is still on the rod?
A2. Yes. In fact, that is best way to use the tool because you can get a better grip on the bamboo than on the ferrule.

Q3. Will this process damage a blued finish?
A3. Probably. Do not undertake shrinking unless you have a way to restore the bluing.

Q4. Will it otherwise mark the ferrule?
A4. That depends a lot on the hardness of the ferrule. I have had some emerge clean, but had others where a small ridge is raised at the edge of the bearings. You could keep the ridge as a “decoration”, or roll over it and work it down some. Abrading is always available as a last resort.

Q5. Can I shrink a male ferrule?
A5. No. The closed end of the ferrule is a rigid point that cannot be shrunk. Similarly, you cannot shrink a female over the moisture plug or too close to the welt. I would stay 3/64 inch back from these.

Q6. What is the size range of ferrules?
A6. The tool will close down to 10/64 inch, the O.D. of a number 8 ferrule. It will open to 25/64 inch, the O.D. of a number 23 ferrule.

Q7. How can I pay you?
A7. Easiest method is to Paypal to the address shown on the “Contact” page. If you are not registered with Paypal, then let me know and I will send you a Paypal Invoice. You can pay this with a credit card and never bother registering with Paypal.
