Music Tech DIY • DIY Bushings for Sequential Pro One

Hello fellow wigglers,

Thought I would just share some experimenting I've been doing with my good old hot glue gun.

I've recently picked up a Sequential Pro one and it is suffering from a bad case of sticky keys. Opening up the keybed, the bushings were super sticky and disintegrating before my eyes! So I wondered if I could create a new set of bushings myself using injection moulding.

After taking measurements of the old bushings, I created a mould model and used SLA 3D printing to create the mould cavity parts. After a bit of sanding everything seemed to fit together well.
Before attempting to fill the cavity I used a little silicon mould release spray just to make sure I didn't ruin it on the first go..
But everything went to plan, a scalpel easily removes the excess material and each one takes about 4 mins, so far I've made 4.
After that, I tested the 4 I've made so far in the actual keybed (sorry I will get around to cleaning all the muck off!).
For a first attempt, I think it turned out well, the key travel is probably on the shallow side as the new bushings are a bit on the tough side, maybe also a bit too big. Hard to compare as I haven't played on any other Pro one before. I do have some two-part liquid silicon that I may try next.

Anyway, I hope someone found this interesting! Have a great day/night everyone.
