This episode is all about the wrapping. We need to remove the old wrapping first. This is pretty easy on the tom shells, because they don’t have air vents. Other than Bass- and snare drum. Each has a pressed air vent which needs to be removed. This is only possible with a file or a grinding drill bit. It needs to be grinded until the metal ring comes off. We simply use a screwdriver to pull out the inlay. Don’t use a screw driver if you want to keep the wrapping or if you have a plain wood shell. The safest solution would be pushing the inlay through the hole from the inner side.

Start heating up the wrapping at the overlap with a hot air gun. A spatula can be used to separate the wrapping. It cools down really quickly, so just heat it up again and again. The wrapping of the rhythm traveler is only applied for 2 spots with a piece of double layered adhesive tape. So it is pretty simple to remove it from the shells. There are no glue rests. It couldn’t be easier.

Only getting rid of the sticky tape is not that simple. Heat and a spatula will help. Don’t use any chemicals to get rid of the sticky rests on the shell. They could destroy the wood. The bass drum hoops are wrapped with sticky tape too. There is actually a trick to get rid of the tape. Take a piece of foam rubber to not get burned and roll off the heated sticky tape.

We don’t use the original tom rosettes. Instead, we take these Gibraltar SCSTL4 tom mounts. They are perfect for applying the pads to the usual e-drum tom mounts. The shells need 2 lying upon holes to apply this mount. A vertical line right in line with the lower hole is required. The rubber plate is the pattern to mark the upper hole. We drill the hole and use a file for the precision work. The lower hole has already the right diameter. A test will proof if the mount fits.

We want to mount Neutrik jack plugs from R-drums into the air vent holes of bass- and snare drum. The hole is too small, the quickest way to extend it is also using a file. The hole will be enlarged consistently. We sand the shells to get rid of the dust and dirty spots. It is better for the mesh head if the bearing edge has no sharp edges.

The wrapping foil we use is in a color called diamond grey.
We measured the height of the shell and subtract a few milimeter to have a free bearing edge. The wrapping should always end up around 5mm lower than the bearing edge. It is really hard to draw a straight line onto such long wrapping sheets. Therefore, we improvised by building this device with a white permanent marker. It works this way. We mark the inner side of the wrapping sheet. The distance between marker and wrapping edge can be changed due to this tool clamp. It looks like a MC Gyver tool, but works perfect.

The shell scope can easily be measured with a tape measure. The wrapping should be long enough to overlap itself in order of 2 cm or 1 inch. It is important to cut as accurately as possible. It might happen that the sheet is not long enough to surround big shells like the bass drum. Therefore, we need to divide the wrapping into 2 pieces. The small piece and a big piece. Same story for the tension hoops.

We use this gel glue and a foam brush, which cannot loose hairs. We start off with a piece of around 6 inches. The wrap sheet has to be covered on every spot. We basically roll up the wrap. It would be good to use such tool clamps to secure it. This step is getting repeated a few times until the shell is fully covered. It is really important to push out the air bubbles by using a piece of cloth or a roll.

The big advantage of gel glue is that the screw holes do not have to be taped from the inside. It will most likely not happen that glue is floating trough and rinse the inner shell. It is best to not use too much glue on the very last bit, as most of it will squeeze out. Use a paper towel to get rid of it immediately. Do not use acetone. It will remove glue, but also dissolve some kinds of plastic. The clamps will secure the wrapping until the glue has hardened.

We used 2 belts to press the wrapping to the shell. This is a great solution if your belt is long enough.
As we need to apply 2 wrap pieces to the bass drum, it is best to start off with the small piece at the bottom. It gets applied first as this piece will be overlapped by the bigger piece. Paper sticky tape is a perfect way to secure it.
