What’s on *YOUR* workbench?

Opened up the right shifter on a Shimano Dura Ace 7700 groupset. The ratchet would click but it would not move from the 8th to the 9th position.

They don't make replacement parts and I was worried something wore out and I would have to toss it. Took it apart bit by bit looking for anything worn, turns out there was a bit of metal bent in preventing ratchet travel. Fortunately it was just that.

Got a email from my local bike shop. A lady brought in her bike for service and it had a gnarly puncture on the non-drive side chainstay.

It is an old carbon Rocky Mountain MTB frame that she grew attached too; you could tell from its battle scars. They asked me if I could do the repair and I agreed.

So far so good. It feels really solid after three wraps of carbon and one piece of weave applied from the inside.

I was doing mountain biking seriously around here about 20 years ago.. I still have my old Kona Lavadome, but riding 24 miles cross country/down hill meant it got quite a few mods/replacements.. in fact the only thing stock was the frame handlebars and brakes... Shimano SPDs, XT Hollowtech II, XT gear set/deralliers, Hope titanium hubs, mavic titanium rims, new seat post and seat, and Mazzochi Z2 BAM Light oil forks. For a steel frame hardtail bike it was surprisingly light and nimble.
Folks I rode with had Rocky Mountain etc. always wanted to step up to one but never got to (about 5x the stock bike price!).


Anyway on my virtual bench is my archtop guitar plate generator.. which is getting some updates following some dogfooding.

It's pretty good in that it can take a set of outline measurements, even if non-symmetrical, and fit curtate cycloid curves so the recurve sits on the rim (the curve generator is asymmetrical). It then calculates the wood wedge height above its base.
 
Much to my surprise, my one-off pedal worked prefectly on the 1st try even though it's made up of disparate bits and pieces originally not intended to go in pedals. Fingers crossed that it won't fall apart on the world tour it's going to ;). If it does, at least it's modular and connectorized, so it ought to be easy to fix.
Very cool but that's a lot of faith in so many dupont cables.
Couldn't be bothered with some JST crimping? 😂

I used to greatly distrust almost all connectors and just solder everything, but time proved to me that Duponts are fine. And ubiquitous... If it works for EMG, with their solderless pickups and gadgets, who am I to argue? I'm sure I'll hear about it if my box fails as it travels around the world :)
 
This is the latest thing I’ve been putting together. The PCB I designed had some issues with it so had to do some bodging to get it to work in the prototyping phase but now it’s sounding great. There are still some gremlins that only a new layout and design can sort.

This is 3 FV-1 reverbs in parallel. One of them has a wet/dry mix and the other two are wet effects only. There is also an effects loop that is phase reversible. The 4 effects are mixed in parallel. It sounds huge. Two of the reverbs have shim/mod/ touch and the other has room/hall/cavern. I haven’t tried it wet dry yet but I bet it will sound even better in that setting. At the moment I have my arachnid with a multi tap delay in the effects loop and I am using the shimmer, cavern and modulated reverbs in parallel. I’m excited to put a new design together that gets rid of these bugs.

Awesomeness.

My man. I’ve done quite a few modular builds like that and they’ve typically held up just fine. Personally, onboard preamp builds make me a bit more nervous, especially if they’ve going to NAMM.

And I’ve repeatedly recommended you for potential pedal builds over at TB from time to time, it’s just way too much work for me for the most part due to all the offboard wiring. That does make for super easy repairs and mods though…

I hear you. I hate wiring. It feels such a downer after the fun of stuffing the board. This is why I much prefer onboard stuff. That, plus everyone makes pedals. Too much competition. Pedals are real work, man! And I'm surprisingly lazy.

Having said this, I will have a lot more time on my hands once I retire in October, so I might actually end up making some pedal(s). Who knows? Main blockage is the tariffs, since most of my customers used to come from the US. I just never know what I'm waking up to on any given day.

Finished the carbon repair on the chainstay and touched yo the finish. Not cosmetically perfect 100% but that's because

1. The frame is full of scratches, tire rash, and paint chips from hard use and,

2. The bike shop gave me the frame like this but extremely dirty. I would have to disassemble everything to do better and handling this with a heavy suspension fork was challenging. I am also not cutting hydraulic lines with dot fluid in them.

Great job. Do you have a bike stand? I highly recommend it, just clamp on the seatpost and it does handle well the added weight of the fork.
