HMH Questions, Answers and Tips



Q. What are the advantages of tying and fishing tube flies?

A. Tube Fly Advantages


Q. Do all HMH vises have interchangeable jaws?

A. Every HMH vise except the Spinner, which is a dedicated tube fly vise, has the interchangeable jaw feature. 
Please follow this link to learn more about HMH jaws.



Q. How do I change and install my HMH jaws?

A. Changing jaws is simple and requires no tools. The jaw is threaded at the rear, and screws on to the drawbar inside the collet.

To remove the jaw, release any pressure on the cam lever. Hold the cam lever with one hand, grasp the jaw with the other and simply unscrew the jaw and remove it from the collet.

To reinstall the same or a different jaw, first screw the stainless adjusting knob all the way towards the brass locking ring. Insert the threaded end of the jaw into the collet sleeve and screw it in by hand. Hand-tighten the jaw as much as you are able until the jaw gape is oriented vertically. If the jaw tightens up slightly past vertical, merely back it off so the gape is vertical.


Q. What is the proper hook placement within the jaw?

A. Please follow this link to learn more about hook placement in HMH jaws.

Q. I want to start tying tube flies. What do I need to get started?

A. HMH offers several tube tying products. The HMH Starter and Premium Tube Tools will fit any existing vise and is a great inexpensive way to get started tying on tubes. HMH also offers a Tube Vise Converter which screws into our Spartan and Standard vises. Simply unscrew the conventional jaw, replace it with the Tube Vise Converter, tilt the adjustable head to horizontal and you're ready to tying tube flies on the finest full rotary tube vise available. Please follow this link to learn more about HMH Tube Tools.

You'll also need some tubes. Our Plastic & Conehead Assortment is a great way to get started. We have an extensive selection of tubes available. Please follow this link to see our entire range of tubes.   And,   Our Tube Fly Demo is also very helpful.


Q. How does the rotary feature of my HMH vise work?

A. When the cam lever is locked into position (as when holding a hook), the vise head can be rotated 360 degrees in either direction by twirling the cam lever with your finger. Use the brass locking ring to adjust how freely the vise will rotate.


Q. How do I adjust my vise for different hooks sizes?

A. The fine, custom threads on the collet and adjusting knob make it easy to execute very quick and precise adjustments to achieve the optimum hold when changing among hooks of different diameter. While holding the selected hook between the two tangs of the jaw, using 2 or 3 fingers of the other hand, hold the cam lever at about a 45-degree angle relative to the collet (curl your fingers over the top, around the back, then under, to cradle the cam lever). With the thumb and fore finger of that hand, screw the adjusting knob back until it touches the cam lever right at the "break" between the flat and rounded portion of the cam. The adjusting knob is properly positioned for a given hook diameter when the jaw just begins to grip the hook when you lightly depress the cam lever past the break. Continue to depress the cam lever using the heel of your hand all the way so the flat section is flush with the adjusting knob and locks into position. When properly adjusted, you will be able to depress the cam lever without excessive effort, and the cam will be perpendicular to the collet with the flat of the cam bearing fully against the adjusting knob.

TROUBLESHOOTING

Jaw does not release when cam lever is lifted...Adjusting knob may be too far back towards lever. Check collet funnel for signs of wear. Lubricate jaw shoulders.


Vise head does not rotate smoothly; clicking noise while rotating...Ensure derlin washers are properly seated; ream inside diameter of back pair of washers to prevent binding with collet threads.


Grinding noise as cam lever depresses; requires too much effort...Cam lever or adjusting knob are either corroded or worn. Scotch-brite and lubricate or replace.


Locking ring comes loose, or tightens excessively while rotating head...Ensure locking ring setscrew is tight; or that the nylon tip has not been worn off.


Jaw will not hold hooks like it used to...Inspect cam lever and adjusting knob bearing surfaces; clean and lubricate. Ensure cam lever is fully and properly engaged. Ensure hook properly placed in jaw. Jaw may be splayed or edges worn - replace if necessary.


Jaw doesn't hold hook securely right out of the box...Make sure the cam lever is positioned properly. The cam portion of the cam lever must be riding against the adjusting knob for the vise to work properly. The "HMH" stamp on the cam lever needs to be right side up and visible at all times (for right-handed tyers this would mean that as you're facing the vise the curve of the cam would resemble a backwards "c" shape). This will insure proper orientation of the cam lever.


Jaw rotates when cam lever depressed repeatedly...Ensure jaw seated completely on drawbar threads and is snugged up tight on o-ring. Jaw shoulder and/or collet funnel may be uneven - try scotch-brite or call 1-800-335-9057.
