I am now changing my seat to a fibreglass seat (see image below) and wondered if any one had any advice for a different mounting solution. Maybe even directly mounting to the back or underneath of the fibreglass seat? I have researched how to correctly drill fiberglass so I guess this is an option but comes with a risk of damaging the new seat. Unfortunately, I think the transducers are too large to install within cushioning/padding in the seat.
I've experimented with quite a few different things (for sure no where near as much as others, but enough...). It always comes down to a couple things I've learned:
- the more direct you have it really to the seat (or padding) the less isolation you need. Or alternatively, you don't need to have the volume so high, so that everything else is impacted. Same for the pedals. I found it so much easier to just mount the transducer to the heel rest, rather than try to have the entire pedal tray vibrating and then need all sorts of complicated isolation. I'm sure other implementations are 'better' than mine, but I'm quite happy (and I'm sure others are very happy with their approach as well)
- it seems to me that a huge amount of time is spent on isolation and related methods. OK, fine. But I wonder sometimes if there is just better transducer placement to be done first. Especially for more simple setups (then you have the complex rigs you see around here, and yes, that's a different story....) Yes, you may still need/want isolation, but I think it can be far less complicated if you really try to get those transducers more directly mounted to the seat, or closer to our body.
I realize people might prefer not to 'mod' their seat or whatever else. I get it. Drilled holes are permanent. But at some point I think we need to ask why not? Especially if it's underneath where no-one can see it. I mean, there are situations with complicated setups and interferences, where it just cannot work to direct mount. I guess there are also situations where a person might want to preserve the seat in case they want to sell/replace it later. Warranty claim for a rigid/fiberglass seat??
Or, alternatively, I don't know your seat, but perhaps the padding is removable/replacable? Maybe it's possible to just get a set of replacement padding? Someone with very basic sewing skills can likely make a couple replacement cushions (so you don't damage the originals) in about 10 minutes (it's just foam, with a cloth covering...). Heck, foam, some material, and some spray/fabric glue can do a decent job if you know where to put the seams/edges. Even if it's just to 'test' or try something......
A couple other ideas, but both would be aimed at trying to direct mount one/both of your current transducers direct to your seat.
- for $10 or so, get a role of really high strength permanent tape/adhesive (like 3M VHB). It's stronger than I thought. And it is removable so it's not as 'permanent' as the description implies. But you have to apply it properly. That's an easy/cheap test to see if it could withstand the vibration, while enabling a direct mount. BST-2 is what 25 watts? Some people will say yes/no..... just give it a try for yourself and then you know if something more complicated is needed.
- the other option I can think of is to make/fabricate some sort of mount for the seat bottom (maybe 3d printed, or just simple metal work with some alum strip or channel. Then maybe use a high strength epoxy to attach the mount to your seat, then the transducer to the mount. That would be a bit more permanent than the VHB option, but no holes, and at least if you remove it, it's under the seat and can be cleaned up after removal.
