Foam cones

[spindrummer82]

I read the links that were posted with how to make the bridge type trigger. In one he uses a semicircle of foam and the other a cone. I was just wondering how hard this foam is. Is it more styrofoam hardness or more like a squishy foam. I have some squishy foam left over from lining my drum cases and was wondering if I could use it.

I am pretty sure that the semicircle and the cone are to be one and the same. If I recall the post correctly, it detailed cutting out a three inch circle out of construction paper, then cutting it in half and rolling THAT into a cone. From there, the next step would be to fill the cone with spray silicone rubber (never used it before, to be honest). After making sure the top is flush, so that it would seat on a bridge correctly, you would then let this dry.

The consistency should be pretty rubbery after it sets correctly, which i would think would probably take a few days. If it were too rigid, I am not sure that the vibrations from the head would get to the piezo, which would be adhered to the bridge and then to the cone.

I might be wrong, so if someone out there knows better, please chime in . . .

I made those diy cones because i couldn't find any of the roland ones to buy a few years ago.
I think the roland ones are available to buy from Musicians Friend for $4.99 so save yourself the hassle of making your own.

I was really just wondering what the density of the cones is.

The foam has to be pretty firm to transfer the hit from head to trigger, but it doesn't have to be cone shaped.As long as you make good contact between head and piezo you could have a cynlinder type shape or just a square piece of foam.
The roland ones are more like a rubber type foam if that makes sense.

Have you ever seen the children's floor mats that connect like a jigsaw puzzle? I believe these are made from a closed-cell foam. Well, I think there are some GN posts describing how some people have used these mats to make the cones. If not, I must have seen the posts on another forum.
