2 lugs, including metal angles need to be applied to be able to measure the exact diameter. The angles are from r-drums. They get applied with m4 screws. It is best to also mount m5 screws. We measured the distance between the screws and the inner shell diameter. It is very important to not make the discs too big, as there has to be enough space to move them up or down without them touching the normal lug screws. They take away around 5 mm in this case.
We order the discs at blechking.de. This company is specialized in metal sheet cutting. We choose aluminium as material because of the light weight. The metal sheet should have a plain surface and not be thicker than 2 mm. The shape should of course be a circle. It is really important to submit the radius, not the diameter. Pretty simple. Now just press order and through the magic of an incredible shipping company, it will be delivered within a very short time. We ordered discs for toms and bass drum.
It is really tight. The circles appear to be a little bit too big. A circular can be helpful to determine the exact middle of the disc. I hope everyone paid attention in geometry class. The shells have 6 lugs, so we need to divide the cake into 6 equal pieces according to the lugs. The spot for the holes has to be marked too. The decoupler from r-drums has a dimension of 40 x 40 mm. That means we need to make a 40 x 40 square and the spots for jack plug and the cable clip. The spots need to be punch marked before drilling.
We drill a 4mm hole for the cable clip and 5 mm holes for the angles. The hole for the jack plug has to be as big as the jack plug winding. Fettling is required to remove the sharp edges. We made the mistake to not measure the inner shell diameter as accurately. As a result, we have to take away material near the large hole to create space for the lug screw.
Another big mistake was spray painting one side of the metal sheets with a cheap paint which will not last and does not look good. So we improvised and applied all inside parts to the painted surface. Of course after sanding. A pattern is needed to cover everything except of a square in the middle. It should dry for a few hours. Metall plates have the disadvantage to produce noise. This will lead to loud acoustic noises of the mesh pad.
A way to damp the discs and to prevent them from swinging is applying rubber sheets to them. The sheets are made with the help of patterns. There should be enough space for the rim piezo, jack plug, metal angles and the cable clip. Again the surface needs to be sanded before gluing the rubber. Spray adhesive is the best choice to glue on every kind of material. As you can see, the holes and the spot for the rim trigger stays free.
A test will proof if they fit before copy them onto the rubber sheets. This rubber material is called foam rubber and really easy to work with.
The rim piezo gets attached via foam adhesive dot with a smaller diameter to ensure a more sensitive trigger result. The dot needs to be smaller than the piezo. The decoupler is dividing head- from rim piezo and the rest of the shell. The dot is again smaller than the piezo. R-drums labels the ground cable of their piezos as it does not mean the black cable is necessary the ground cable. The polarity of a piezo can be interchanged despite the cable colours. The guys from r-drums measure every piezo with an oscilloscope and mark the ground cable with a white ring.
In this case the cables get shortened and marked again. We apply some heat shrinking tubes before continuing. We remove the protective layer near the hole for the jack plug. The jack plug and its nut are only made out of plastic in this case. So be very careful when using a wrench. The pieces need to be connected in a specific way. Find the download link to the wiring diagram in the description. We shrink the heat shrinking tubes near the hole to bundle the 4 cables.
The cable clip will be applied with an M4 screw and a few washers. The clip ensures that the cables are not moving and cause rattling noises or destroy their isolation. Now it is time to apply the metal angles. As the aluminium disc has to be a bit lower than the angle bottom, it is best to apply a longer m5 screw and an extra washer to lift the angle up. This depends on the position of the shells lug screws.
Thanks for your EXCELLENT audio video presentation...God bless you
Very lovely series of videos you have! Thanks, am enjoying them!
jupiter909 Thanks for your comment:)
I made it up to this video, this is where I stop. Well done guys but unfortunately I didn't pay attention in geometry class
I had a general question regarding this DIY approach and "positional sensing" as used in the Roland TD30 and TD50 modules. Would building and correctly wiring the piezos work with the positional sensing feature of those modules, that you are aware of? I understand that in order for it to work, there is a computation that occurs between the head and rim piezos that is required. Just curious what modules you have tried the drums on and what works and what doesn't.
hi! great explanation, thank you for that. I was wondering how thick the foam rubber is you use to damp the discs?
Awesone video series :)
I'm planning to build the trigger systems just like that and asking myself if using 5 mm (or whatever thickness) MDF disks will also do the job or if it does not transfer the vibrations for the rim piezo accordingly. Using MDF disks would also not require damping the disk itself.
Thanks and keep up the great work!
Thank you:) Yes, MDF works aswell.
Sorry i didnt get why the aluminum plate was necessary… would it be alright to do it only with, say, jobeky internal triggers and that’s it?… thx so much
@ Antonio: It is because of the waveform. Read this article and you will understand: www.v-drumtips.com/piezos/
Muy bueno el tutorial listo para la conversion....
Would internal side triggers, like the Triggera Intrigg from Thomann be good enough for the toms?
didnt understand why do you interchange the polarity of the head piezzo
Do you recommend applying a dual trigger on a tom-tom?
I'd like to have a tom-tom with a cowbell or other effects.
What material would you say the R-drums decoupler is made of? Is it like more of a mouse pad feel or yoga block?
I love all of Rdrums designs but I can't afford shipping to the states so I'm trying to re create them as close as possible. Thanks!
Non of both. The material is a foam, but with a specific density. DIY blocks will most likely not work. I tried that already and it was a nighmare.
NICE
i hope you make a DIY hihat trigger with stand just like the roland VH11
i'll make my own DIY edrumset soon thanks to this channel
emarukun You are welcome! I struggle a bit with cymbals. I think it is not possible to make such good cymbals. And there is also an alternate version of the VH-11. Check out Jobeky drums, they offer such a hihat for half the price:)
Very good. Earn one more subscriber. What is the material of the kitten?
Thanks? The material of what? :)
Great video...
Awesome!
Its time to think about your own - mass production line? :))
Aleksandar Savic I thought about that, but I am not sure if I will have enough customers, as this product would be expensive.
Vdrum Tips Thats thrue, but everything could be settled in few different quality grades. For example shells, instead of Pearl Traveller used, could be made of - 10-12`` PVC tubes, or from raw wooden shells 10-12`` , inner metal disc, could be - plastic one, pad lugs could be some PRC bulk buy, etc......
Aleksandar Savic That would be an idea.
I really appreciate you making this video, but I tried to make it and the results were very disappointing. I'm following this design on a 14 snare and I'm finding that the aluminum vibrates/reverberates and causes all kinds of cross talk between the 2 piezos. Did you have the same problem with yours? If this design works then the magic must be in using the exact right material for that black isolation block. I've tried various types of foam, each with equally bad results. What material should I use to make that? I don't want to order it all the way from DE, I'm in the US and looking for materials that can be sourced locally (i.e. what's it made of?).
Sorry to hear that, it could be the plate is too thin. The isolation block is specially made for this purpose, you cannot use any foam. It is absolutely worth it to buy the original foam from R-drums.
What piezo measures did you use for the rimshot and for the pad? I see that there are 2 different measurements.
Are they 35mm and 27mm?
Bryan García yes
I'm planning on purchasing yamaha dtx502 module and wants to do diy 3 toms single trigger with mesh. Also I already have the yamaha dtx xp80 pad for snare. is single trigger enough? do you have recommendations on where to start if I follow your video? thanks
+Ferds G A snare should have 2 triggers for head and rim shot. Just start with a tom pad and see how it works.
Hi I was just wondering why the metal sheet shouldn't be more than 2mm thick? What would happen if it was for example 3mm thick? Thanks!
+MrDalankyman It can be as thick if you want it to be. It would actually be better if it is 3mm, as it will cause less noise, but slightly more weight.
+Vdrum Tips Awesome, thanks for your help!
They using round metal plates. But can i use wooden plates? And also forgett the rubber plates?
Thankyou :D
Material might be too weak.
Can the inner plate be made from a high quality plastic or carbon fiber opposed aluminum? Thanks'
Yes, Why not. I just went for aluminium. But it can be any solid material.
I figured so, thanks
Can u use steel instead of aluminium ? Or any other material?
ProsPlayFps Any material that is strong and does not vibrate.
I have not understood why one piezo goes directly to the plate and the other to a large piece of "foam".
One directly on plate is for rimshot and cross stick. Foam isolated one is for head strikes only. Also known as dual zone trigger.
Hello, I was just wondering when assembling the trigger, is it necessary to have a decoupler for the cone and piezo? If not, do you have any ideas of materials i can use as a substitute for the decoupler.
yes, otherwise the head piezo is getting triggered by hitting the shell. It needs to be isolated. You can use rubber washers or foams. The problem is that it has to be ideal. Not too much, but also not too less. This is why I strongly recommend using the decoupler from R-Drums, they only cost 5 bugs each and even supply a metal surface for the head trigger. I was doing a DIY trigger with my own decoupler material. It was horrible.
Vdrum Tips oh ok, thank you very much. Soon i am planning to do this conversion very soon. I will just need to buy the toms and snare. I also have one more question, what dimensions were the snare and toms in the pearl kit because i am curious whether or not my drum rack is sturdy enough to handle the weight(i have an alesis dm10 studio rack). I plan to have 2 10' toms and 1 12' floor tom but i dont know how long the height would be. I am only curious for the toms, for the snare i will be mounting on a stand. Again thank you for your help. :)
the snare is 13x5 the toms 10,12,14x4,5.
I want one badly! ^_^. Drumtech ships worldwide?
Manx Keys It seems so: www.drum-tec.de/shippingcosts.php
What are the diameters of Piezos?
27 and 35mm
Brilliant!
It serves to Alesis dm6?
It should, on the website it says the triggers are compatible with other e-drum brands.
man to buy all those drills paint, time all the other stuff , would be cheaper to buy one
Damp Patch but where’s the fun in that?
all that trouble why not just buy a roland trigger lol
Herbert .Gatchalian It wouldn't have a centered cone like the advanced pads from Roland. My goal is to build an high end e-drumkit. And rim triggers wouldn't look good.
