Karl's V20 variable seat angle solution

[Robertas]

Great to see that you are doing this!

I asked the manufacturer of the hinge about this, and he recommended gluing it only, so I did that, but found that the screw holes were very helpful in fixing the position, so I left the screws in also for extra safety. One or the other on its own is probably strong enough also.

Your picture looks like you have two separate hinges side-by-side. Is that true? In that case I would definitely glue them to avoid that the smaller one rotates against the lower base of the seat and increase bonding strength.

Thanks for the answer. Yes, it`s two separate pieces as seller did not have one 15cm piece, just 10 and 5cm.

As I said, I would glue this to the seat on both sides to increase strength. Any MMA glue is probably ok for this, as recommended by the carbonhinge company.

Also, I found it helpful to practice on something small with the MMA glue to get a feeling for mixing and applying it correctly, before applying it to the expensive carbon hinges. Gluing those was certainly a bit scary for me, but then it worked out well and was easier than expected.

Therefore, when you order 2-component MMA glue, get plenty of spare mixing tips so that you have enough to practice, as they are single-use only.
