The procedure below refers mainly to units with rubber tubing between the trackerbar and the lead tubing. However, most of the information is also applicable to units that have lead tubing from the trackerbar to the stack. The following set of pictures has been re-sized so they will fit onto this page. The original pictures (each 160K in size) are available by clicking on the picture. You will have to use the "BACK" feature on your browser to return to this page.

To insure the best looking job possible, it is imperative that you measure, as best as you are able, the existing tubing lengths from the trackerbar to the other end of the lead tubing. It would be ill advised to attempt replacing the trackerbar tubing using this treatise without reading the ENTIRE treatise first. Taking a few pictures and lots of measurements will always help insure a better looking job. Also, if you have lead tubing from the trackerbar to the stack, you will need special reducing nipples and about 150 ft. of trackerbar tubing. Furthermore, you will have to ream out the holes where the lead goes into the wood with a drill bit to insure a tight fit.

In this picture, the trackerbar has already been removed from the mechanism and the tubing has been broken off at the nipple. You'll notice that half of the nipples on one row have been bent out of their original position. This was done with a drill bit that fits almost snugly into the nipple. They need to be moved approximately 1/8"-1/4". After bending the nipples, I submerge the trackerbar in gasoline and leave it outside for three days or until the tubing gets so soft that it basically falls off. Sometimes a stiff wire brush is needed to remove stubborn pieces and in rare cases, a knife, or other cutting tool, will have to be employed to clean away all evidence of the old tubing.

Here, both rows (at the receiving end) have been properly 'bent' out of position, allowing easy access for installing the new tubing. Like the trackerbar, there were only two rows of nipples. Now there are four, so to speak.

Once the bar has been cleaned and polished, I pre-size, cut and install all the tubing on the tracker bar and put it back in the mechanism. It is in your best interest to cut the tubing a couple of inches too long. It's easy to cut a little excess off but quite another matter if they are even a little bit too short. It is noted here that this is NOT the only way to continue the process and admittedly there are cases when it is easier to install the bar without any tubing and retube each note one at a time. In that case, it is advisable to start tubing from the center of the bottom row and work your way out to the ends. The pattern I follow is basically back-and-forth in that I install a tube on the right of center and then the left of center and progress outwards to the ends. If you attempt to switch between the lower and upper row of nipples instead of completing the bottom row first, the tubing will not lay correctly since the upper row of tubing must lay on top of the lower row as it did originally.

This picture is here for only two reasons. First, it shows what the tracker bar looks like when it's polished. Second, and more importantly, it shows the method I use to keep the upper row of new tubing out of the way while I am connecting the bottom row to the stack. The piece of wood is cut just long enough to apply pressure on the walls of the spoolbox. Just about anything that will keep the upper row out of your way will work just fine.

And's here's another way!!!!

HI Joe, 

Sounds good. It's going into the technical tips.

John--Found a real quick and clean way. Take a Wagoner heat gun and it will
soften the rubber, but not the lead. Use caution tho. I tried to melt a
piece of lead tubing, and one really has to hold it on it for quite some
time before it will melt the lead. Went to the old rubber and it gave up
right away! Old stupid me will try any thing once ! Give it a shot------it
works out real good-------------Thanks  JOE  jodo@tctc.com

HI Joe,

The best way is to break away the majority of the tubing, up to
about 1/2" from the lead. Then locate a drill bit the just fits
into the lead tubing. Careful not to push it in too far. Then
use needle nose plyers and break/crack the rubber, and pick out
pieces. I use dentist picks.

The other way involves gasoline... and is a little dangerous
and messy. But it's not much work. Basically dissolve the
rubber by soaking it in gas. And all the lead tubing has to
be removed from the upper section, spoolbox, etc.

If the tubing is not terribly hard, you should try pushing the
tubing further on. That's right, ON. Then sort of pry it off,
using the wooden feed-through board as the focal point. I have
a mini crowbar about 5" long, but a screwdriver can do the job.

I must say I play each re-tubing by ear. It really depends on how
stubborn the tubing is. Most often it's, 'crack, pick, crack, pick'.

Have Fun,

John

Hi John--Tried to send a min. ago, but had wrong add. Is there any way to
remove brittle tubbing from the lead tubbing on a Simplex Transposing
system? The lead tubing 'seems' to be excellent. Really hate to re-tube the
whole system, mainly because there is so little clearance between the player
stack and the piano action. Any suggestions would be helpful.

This tool was hand made from a piece of 1/4" X 5/8" steel stock. After cutting the groove in the center (9/64"), the inside edges of the groove were beveled to create a knife sharp edge. To use the tool, insert the groove, with the beveled edge down, behind the old tubing and wiggle and pull the old tubing off. The device is similar to the tubing puller sold by Player Piano Co., but it is MUCH stronger and it has the knife edges which will cut any old tubing to bits. Notice the pieces of old tubing on the bench. That's all that was left.
