How Toget A Dent Out Of A Telescope Tube. The tube is 12.75" long and the dent is just right of center, 5.50" in from the end. In the picture it is between the horizontal and diagonal scratch just right of center.. I have an old Skywatcher 130mm from about 2005 that has a bit of a dent half way down the tube. That shouldn't affect the telescope much in terms of light gathering I assume? I.
Dents in telescope tubes can be unsightly, and can also impact the performance of the telescope. Telescopes with dented tubes may be difficult to use, and the dents can create air pockets that can cause turbulence in the light path. Fortunately, there are a few strategies you can use to remove a dent from a telescope tube.
Using Heat
Using heat is one of the most common methods of dent removal. The idea is to use the heat to soften the metal and make it easier to work with. The most common way to do this is to use a heat gun. It is important to use caution when using a heat gun to make sure that the metal does not become too hot. If the metal does become too hot, it could melt or warp, which could make the problem worse. Once the metal has been heated, it should be allowed to cool before attempting to remove the dent.
Once the metal has cooled, the dent should be able to be pushed out with a rubber mallet or a wooden block. If the dent is still not coming out, the process can be repeated a few times. It is important to remember to allow the metal to cool before each attempt. Once the dent is out, it is also important to check for any other damage that may have been caused by the dent.
Using a Suction Cup
Another strategy that can be used to remove a dent from a telescope tube is to use a suction cup. The suction cup should be placed over the dent and the air should be slowly released. As the air is released, the suction should pull the dent out. This method is generally not as effective as using heat, but it can be a good option if heat is not available.
It is important to use caution when using a suction cup to make sure that the material is not damaged. If there is any damage to the material, it could make the problem worse. It is also important to remember to release the air slowly to make sure that the suction is strong enough to pull out the dent.
Using a Dent Puller
A dent puller is a tool that can be used to remove dents from metal objects. The dent puller works by pulling the dent out with a vacuum. The vacuum pulls the dent out and the metal is left with a smooth surface. It is important to use caution when using a dent puller, as it can cause damage to the metal if used incorrectly.
When using a dent puller, it is important to make sure that the surface of the metal is smooth and that the dent puller is firmly attached. It is also important to make sure that the vacuum is powerful enough to pull out the dent. If the vacuum is not powerful enough, it could cause the dent to become worse.
Removing a dent from a telescope tube can be a tricky task, but it is not impossible. Using heat, a suction cup, or a dent puller can all be effective methods of removing dents. It is important to use caution when using any of these methods, as they can cause damage to the metal if not used properly.
Dent repair on a tube
If the dent is near the primary it is less likely to effect the scope than if its close to the corrector plate. The only sure fire way of checking the effect of the dent is a. If it is in good collimation the dent is cosmetic and you might just live with it. If you are confident of your collimation skills and cannot restore good collimation., How Toget A Dent Out Of A Telescope Tube.
