Model 233047 This is one I have used for many. many years. You can tell by the missed hammer hits! This is the original made by Rex Bullock when he had the NOVUS tool company in California It came with a brass and plastic saddles, but no lead. I made the lead one you see in the picture out a G# lever pearl holder for a MKVI alto!</div>

Rex bought Ed Myers and subsequently sold Ed Myers to Jeff. When Jeff was in my shop I showed him how I drilled out a hole for a piccolo test light so I could light the work area and maybe see what I was hitting. He incorporated that into the design and made a number of other improvements as well. A nice workable tool. Click the "link" above to go to his site and see how different the tool is from the original shown here.</div>

<i>"<span style="background-color: white; color: #666666; font-family: Arial, Helvetica, sans-serif;">The ultimate pin removal tool: the J.L. Smith Flute Key Pin Punch, allows you to safely and easily loosen even the toughest pins without ever harming the keys or shafts. Two pin punches (pointed and concave) allow you to work with pins that are flush or slightly raised and a third needle punch with a pilot sleeve allows you to tap loose any longer pins. A spring-loaded ball holds the punch in place, allowing both hands free to hold the key and hammer. The tool also comes with 4 individually shaped anvils to support various keys on flutes or piccolos. Once you’ve tapped the pin loose just use your </span><a href="http://www.jlsmithco.com/PLIERS_2/JLS-WHOLE-SPRING-PLIER" style="background-color: white; color: #8a0000; font-family: Arial, Helvetica, sans-serif; text-decoration: none;" target="_self">J.L. Smith Whole Spring & Pin Pliers</a><span style="background-color: white; color: #666666; font-family: Arial, Helvetica, sans-serif;">* to gently pull the pin free. The J.L. Smith Flute Key Pin Punch even comes with a mini Maglight® that slips into position at the top of the tool and lights the working area. Every aspect of this beautifully crafted tool has been carefully considered and engineered for optimal accuracy and ease of use. The J.L. Smith Flute Key Pin Punch is made in America by the J.L. Smith engineering team. Individual anvils are available for easy replacement when they get overly worn and it comes with the J.L. Smith 100% lifetime warrantee so you can depend on this quality tool to last."</span></i><br />

Model 2780 is a masterpiece. Not only for unpinning but threading too! Very stable, multiple attachments...and did I mention, IT THREADS! Fast becoming my favorite for a few reasons. I can actually see what I am doing! With the large throat area there is no need to crank your neck to see where you are punching. If you shop is well lite, you do not need auxiliary lighting to see the key/punch relationship. Cool.</div>

<b>Well, lets talk about them. What makes a bench motor a "bench motor" is the shaft that the motor spins on is drilled through, like a lathe. You can insert a rod all the way through. </b></div>

Add a few inexpensive accessories and you’ll be able to sand the corks on clarinet mouthpieces, mount a small buff to finish color buff clarinet and flute keys while they’re on the horn. You can spin drills of all sizes. The N99 motor comes complete with hollow extended shaft, precision ground with a 3/8” (9.5mm) Jacobs chuck ensuring true center, an aluminum hand brake and foot switch. 1725 speed."</span></div>

For example: Tapping and Die work. Slotting a rod screw. Holding a valve stem on a piston to unscrew it when it becomes corroded into the piston. It is an essential tool for any shop.</span></span></b></span></div>

On or off. Functional, and ones I have used for over 42 years. The smaller version (N97) is basically a washing machine motor on rubber mounts. I find it workable, but not as stable as its bigger brother the N99. My choice here is the N99.</span></span></b></span></div>

In comes the Votaw Tools 2621 DC motor bench motor. Basically what you are getting here is a Sherline Mini Lathe head mounted on an adjustable base. I like it! With or with out a foot pedal you have total control of the speed. Pinning a clarinet? No more rotating the chuck by hand. Set the speed slow and let the motor do the work.

<br />
Nothing like it! The world of musical instruments cannot exist without it! From sax neck corks to oboe pads, synthetics just cannot compete.<br />
<br />
Here are a few videos that show cork production.<br />
<br />
The first video is epic. OSHA would be astounded at the methods used!<br />
<br />
<a href="https://www.youtube.com/watch?v=Z8C7CCD-4oI" target="_blank">Old Black and White footage.</a><br />
<br />
The next video is a bit more modern and gives great explanation to cork production. Even though it focuses on wine cork production, you will learn a lot about what makes it work!<br />

Luthiers will use it to put a French Polish on guitars.<br />
<br />
Woodwind repairers will use it as glue.<br />
<br />
<br />
There are three forms of shellac: 1)Flake shellac, both waxed and de-waxed. 2) Liquid shellac, flake shellac mixed with denatured alcohol. 3) Stick shellac, flakes melted into a stick or round.<br />
<br />
Before we had contact cement and "hot glue" (the type used in crafting), shellac was it. The repairer would spread a thin layer of liquid shellac onto cork for key work and let dry. By heating the key, when placed onto the shellacked cork, the heat would reconstitute the shellac and when cool would adhere the cork to the key.<br />
<br />
For pads, the liquid shellac would be brushed into the pad cup, then heated with a flame to burn of the alcohol.Once the alcohol was burned off, the pad would be placed into the cup which then cemented to pad to the cup. It would be necessary to bend the cup to get the pad to cover the tone hole with this method.<br />
<br />
Another method of pad retention using shellac is the melting of the stick shellac into the cup. This provides a thicker "bed" of shellac which facilitates the "floating" of the pad on the shellac to obtain a level pad in the cup over the tone hole, without the need to bend the cup to get the pad to cover the tone hole..<br />
<br />
You might be surprised where shellac comes from! It is total natural and "green!"<br />
<br />
Watch this video to see where it comes from, and how it is produced.<br />
<br />
<b><a href="https://www.youtube.com/watch?v=lQcQ0yuekZ0" target="_blank">Video</a></b><br />
<br />
Another fascinating fact about the shellac, besides how long it has been used in musical instrument building, is that in 1922 , a 2oz. tube of soft shellac cost $4.50. That same year, you could have bought a silver plated, gold lined bell, bass saxophone for $275.00! This shows how difficult it was to obtain and manufacture in 1922.<br />
<br />
At CIOMIT, we value this fine natural glue. Enjoy the video!<br />

This blog will pertain to everything repair. I will share my 42 years experience with you in multiple forms. Please bookmark the page and check in now and then, My schedule is busy with www,ciomit,com, but my goal is to help you understand the repair side of music. This is for both repairers and musicians, so visit often. Brass woodwind strings and percussion, all topics will be covered. Ask questions! I love to help, and my motto is "Re-think everything!"Dr Danhttp://www.blogger.com/profile/03137241934497216560noreply@blogger.com0
