Terry’s Reel #6

This is my friend Terry’s most recent reel project. The intended use is steelhead and salmon fishing with heavy tippets.

Photo of the finished reel. This reel is 3.75 inch in diameter and is patterned after a Hardy Marquis #9, except that the spool is 1/8 inch wider.

Improved Cutting?

I received a lengthy technical education at Purdue University, and as an astute organization they keep track of me in case I might make them some future bequest. So I get regular bulletins from them covering research activities. One of the reports recently caught my attention.

This report concerned ordinary machining, and I am pleased that people at a university would still consider such a mundane thing. The full text of the research paper is here: Organic monolayers disrupt plastic flow in metals

But the summary in the bulletin is what I found interesting:
“The researchers previously showed that the application of a permanent marker or Sharpie, glue or adhesive film made it easier to cut metals such as aluminum, stainless steels, nickel, copper and tantalum for industrial applications. Marking the metal surface to be machined with ink or an adhesive dramatically reduced the force of cutting, leaving a clean cut in seconds. Now, they have discovered how these films produce the effect.”

Can this be a technique for us home shop machinists? I did a quick and dirty test, marking a piece of 6061 with a Sharpie.

Then I took a pass at .020 radial depth. The bit is HSS.

Was cutting easier/cleaner where the Sharpie covered? I could not tell a difference. But this was just one quick experiment.

Reel #5 by Terry

This one is a 3.5 inch trout reel, similar in design to previous work by Terry, but an improvement in details.

This view of the back of the spool shows the Delrin ratchet, which is one piece with the bushing. The bushing runs on a stainless spindle. Terry says he has a good fit of the bushing bore, that a spin with the finger will cause 6 revolutions (in the absence of a pawl). Editor: for my reels I have been using 5/16 inch ground stainless shaft material and just drilling the bushing with an 8 mm drill. I believe that when Delrin is drilled, the bore is slightly small than the nominal drill size. The fit is good but it is not as free spinning as this.

The frame windows were cut with the frame mounted to a rotary table that is at right angles to the mill bed. For a clean inside surface, he made the final pass as a climb cut around the each window.

The spring wire was bent freehand and so is not a tidy fit to its two pins. This really has no effect on spring action. Having a bending fixture would help.

Clockwise from top left are his five reels so far: diameters 4.5 inch, 2.25 inch, 3.5 inch (this one), 2.88 inch, 3.25 inch.

Reel #4 by Terry, Trout Size

Another reel by Terry from Idaho. He has been busy designing and making one-off reels for his own use. I think this one is just slightly larger than his first reel. Pictures and captions below by Terry.

Here a 1-1/4” long piece of aluminum is being cut off of a 12” long billet of 3.5” diameter 6061 aluminum in my horizontal band saw.
Editor’s comment: For someone just starting out in reel making, a metal cutting bandsaw does not have to be at the top of your tool list. Vendors like Online Metals will cut bar stock to custom lengths.

This is the reel frame mounted in the rotary table set vertically on on my milling machine.

Now about ½ of the sides are cut out of the reel frame. Note the 2 holes drilled in the top of the reel frame to the right of the area that has already been cut out. These holes are the alignment for the milling cutter to start to cut out the right side of the reel frame.

The reel spool. You can just barely see the Delrin clicker gear on the right side of the spool. The reel frame and cap screw are in the background.

The brass cap screw.

Interface of the reel foot and frame. On this reel, I cut a radius in the bottom of the reel foot that fits the outside radius of the reel frame. I think this makes the reel slightly stronger since I did not remove any material from the outside of the reel frame so the reel foot could fit in a slot. This just leaves a little more depth of aluminum material where the screws that hold the reel seat in place pass through the frame.
Editor comment: This is a small but important detail. The securing screws need to have about 3 threads engagement into the reel frame, and making the interface curved helps. It is also possible to turn the screws around, threading into the foot from inside the frame. I did this on my “Reel 37”. Had to fabricate a long countersink to reach across the frame.

The reel with a machinists scale laying across the top to give you some reference as to the actual size of the reel (3.25” diameter).

Here all 4 of the reels I have completed so far. The newest reel is at the bottom right of the photo.

Third Round, Lathe Bit Grind

In two earlier posts, I have shown tool rests that I made for my 6 inch grinder to help with lathe bit grinding. These have been satisfactory for grinding the end and side cutting edges, but are inadequate support for grinding the top rake angles (side rake, back rake).

I have been influenced by an article that shows how to take advantage of the slightly concave surface that a 6 inch wheel makes on bit surfaces. When this concave surface is stoned, the stone touches just at the top and bottom of the surface, making a cutting edges at the median angle of the ground surface. View the article to see some excellent pictures of the effect of stoning.

Here is my new setup. The grinder tool rest is replaced by a guide for tool holders.

Note the catch pan for grinding debris, a big help in clean-up.

During grind, bits are carried by holders that are guided by the base. Here is a protractor holder for end and side cutting edges and two other holders for the top surface (side rake and back rake).

The protractor makes end and side relief angles of about 9 degrees and adjustable side and end cutting angles. The other two holders make 15 degree back rakes and 15 degree side rakes, one holder for right cutting bits and the other for left cutting.

This is the back of the protractor showing the step that keeps it at constant distance from the wheel.

Here the protractor is used for an end grind.

And here it is used for side grind. For a shallow angle, this must be done with some care as it is possible to wedge the bit and stall the grinder motor.

The two holders for top surface grind have grooves to position the cutter for the compound angle (side rake and back rake) that is needed.

At first thought, it seems that the right cutter and left cutter top surface guides should be mirror images. But my grinder motor interfered with any approach to the wheel from its right side so both of these work from the left side of the wheel.

These sketches help to explain the side rake grinds.

Here the right cutter guide is being used to make the side and back rake angles.

And here the left cutter guide finishes a top surface.

Finally, two newly ground tools.

Yet to be made are two more holders for aluminum cutting bits that will have 35 degree back rake.

Update 28 Oct 2020: Here are the four holders for grinding tool top surfaces. All are 15 degree side rake (per the sketches above). The front two are 35 degree back rake for aluminum and the back two are 15 degree back rake for steel. The notches at one corner are needed for clearance from the wheel.

A Salmon Reel

This is the work of my friend Terry, for whom I have shown two other designs. It is a 4.5 inch diameter reel for “big game”.

Terry has several decades of experience with salmon fishing including regular visits to Alaska and Iceland. I think it is interesting that he chose to make a click type reel. Two pawls may be better than one.

The remaining pictures include his 2.25 inch reel for comparison.

Terry is doing his drawings with Autocad LT. I have reproduced them here but it took several steps to communicate them and turn into jpeg format. If anyone is serious about reproducing this design, contact me and I can provide PDFs with better legibility.

If you combed through this blog, you could find drawings for seven different reels. At the Categories list on the right side of the blog page, click on Plans.

Update 14 Oct 2020: Here is a communication from Terry after I made this post.
“The answer to your question regarding the 2 pawls is that very definitely yes, the 2 pawls make a huge difference in the clicker drag on this reel.. This is not something new to me. In my previous years of salmon and steelhead fishing, I have always turned both pawls on my old Hardy type of reels so they are in contact with the gear and set so they are working in the same direction. This greatly enhances the drag on the reel and with the overlapping palming flange, you can easily handle even the larger fish encountered. I like the clicker drag system, even on larger reel for larger fish because this system is about as simple and foolproof as you can get. I have never had a failure of this type of system, which is not something I can say about more elaborate drag systems on much more expensive reels I have used as well over the years.”

My observation on his pawls is that they are spaced 92.5 degrees apart. Because he has a 31 tooth ratchet, the pawls are exactly 8 teeth apart and so click over simultaneously. I would like to play around with 2 pawl placement and see what different sounds could be had. Maybe something like the Harley V Twin where the cylinders are 45 degrees apart.

Terry’s Second Reel

Terry is bamboo rod maker in Idaho. In June I posted pictures of his first reel. Now he has produced a 2.25 inch diameter reel for a 5 foot bamboo rod.

This is about as simple and straightforward as a reel design can be.

He had this one engraved, and the engraver added some color. At this time I do not know the process; possibly just a chromate conversion coating.

Anodizing Temperature Control

DIY anodizing of aluminum parts is a practical process for home shop reel makers. These earlier posts provide background:
Technical Data on Anodizing.
Water Cooled Cathode
Cool water

I anodize reel parts in a 32 ounce polypropylene jar, and the lid assembly has several features. A reel spool is suspended from the lid by an aluminum “rack”, which both supports the spool and provides an electrical path.

Also visible here are 3 tubes: the big looped tube passes cooling water through the acid solution, an open ended tube is for bubbling air to keep the solution stirred, and a closed end tube is for temperature sensing. These three tubes are electrically connected together to serve as the cathode.

Here is the acid jar with lid and an auxiliary jar for ice and cold water. A small 12 volt dc pump circulates water between the jars.
Two additional connections are provided on the cold water jar, a normally plugged outlet for system drain and an overflow for excess melt water.

This is the complete setup, adding a current controlled power supply, an aquarium air pump for bubbling, my new temperature controller, and an IR temperature gun for casual monitoring.

Before I made the controller, I kept a glass thermometer in the closed end tube and turned on the pump when the temperature reached 21 deg C, and turned it off again at 19 deg C. This required constant vigilance during the one hour process.

This is a close-up of the controller, it is just a resistor bridge (one leg is a thermistor in the closed end tube), a voltage comparator, and a power transistor to switch the pump.
This automatic control makes running the process much more pleasant; I can leave my garage for a while (88 deg F in the summer) and just periodically check on whether ice should be added to the auxiliary jar.

When the process is started, the acid needs to already be at 20 deg C (68 deg F). I get it there by holding it in an insulated chest with some blue ice for about an hour.

Recently I had been getting some cosmetic failures of the process, dark smudges under the anodize coating. I have been able to eliminate these by switching from titanium to aluminum for the anode rack. Not sure why the smudges were developing; I was using grade 2 titanium and so not introducing rogue metals.

Chuck Spider

I finally sold my Sherline lathe, my first machine tool. I could do this because I have made enough upgrades and fixtures for my newer minilathe to produce all reel parts with just it and my mill.

The last consideration was making a thin (.110 inch) disk as the blank for the front end ring. To do this with the Sherline lathe I bought soft jaws for the 3 jaw chuck. The jaws step was .080 inch and that was enough to firmly hold the disk.

More about soft jaws at this post: Custom Jaws.

This would be a good solution for the minilathe also, but there seems to be no source for minilathe soft jaws. I found a good article on DIY soft jaws: Harold Hall’s Soft Jaws. But I did not pursue this because it appears to require a surface grinder.

Instead, I have made a chuck spider.

This is the spider: a hockey puck with milled grooves to clear the jaws. It works with diameters from 2.25 to 3.0 inch.

I had made a similar spider to use with the Sherline 3 jaw chuck, but it was a loose part in the chuck-spider-work assembly and did not work very well (i.e., disk sides did not come out as parallel as I wanted). The improvement here is a draw bolt to keep the spider firmly against the chuck face.

To make the final facing cut on the spider, I removed the chuck jaws and held the spider against the chuck face with just the draw bolt.

And it worked, I got a disk with sides parallel to .001 inch.

The spider has a witness mark for angular positioning on the chuck. This eliminates the effect of any chuck face axial run-out.

A “Perfect” Reel Configuration

An iconic reel design is the Hardy Perfect. I have never had one in hand to photograph but I did borrow a Hardy Bougle from a friend, and it is the same thing except that the frame is raised pillar instead of round.

What is unusual here is the winding plate that carries the knob, the ratchet, and a spindle that reaches through a frame mounted bushing to drive the spool.

Another notable feature in this design is the ball thrust bearing. I have never really understood the reason for this bearing; seems that if you wanted a ball bearing for axial forces, you would want them for radial forces also. I have never used ball bearings, too many tiny moving parts.

What is the real advantage of this design? I don’t know, but I do observe that one face of the spool is accessible for “palming”, to create additional drag.

Here is my take on a Perfect reel.

Because this reel is left hand wind, I had to make left hand threads on the end of the spindle and in the bronze spool insert. Otherwise, line tension might unscrew the spool.

Instead of the ball thrust bearing, I have a plain bearing of Delrin (the ratchet face) running on bronze.

If the reel is palmed, then axial thrust is in the direction that the thrust assembly does not support. On a Hardy reel, this load is taken by a small area of spool aluminum running on the end of the frame bushing. Here, the bronze spool insert runs against the bushing.

This reel is cosmetically defective due to failure of my anodizing process. There are stains embedded in the oxide layer. I think that the aluminum alloy may not be 6061, which is a good anodizer. But it seems quite unlikely that something else would have been supplied.

I did not make drawings of all the parts, but here is what I have.

The pawl is drawing 1090 : pawl. The ratchet is 36 teeth, 36DP 20 degree.
Click hardware is drawing 1091 : hardware.

Finally, this sketch shows overall arrangement and dimensions.

Update 18 Aug 2020: The cosmetic defect in the anodizing must be due to the aluminum alloy. I don’t think it is 6061, which is well known as a good anodizer. I have never knowingly ordered anything but 6061 in this large diameter.
