2/28/2019 UPDATE:
CNC shop said they were going to machine the prototype run the first week of February, but I haven’t gotten anything back from them since, I am reengaging for the third time in the next couple days and will share my results. I’ve been dealing with job changes and a death in the family still, but I’m trying to get this going. I will add this to the text of the post as well.

Sorry to hear about your family, but thanks for the update. Stay strong!

Work on yourself first! This tool will be useful but you’re far, far more important than it.

3/5/2019 UPDATE:
I have reached out to the CNC shop president and my independent rep because the wait is killing me. I’m going to start talking to other shops or in-community makers if I don’t get an answer back soon.

Just let me know if you need any help. For better or worse, I have lots of experience tussling with machine shops to get shit made. 
Unfortunately, your experience is more common than not.

I am in too… I have lots of box switches lying around
3/12/2019 UPDATE:
Cruciformer lives! I’ve met with the CNC shop a couple times since the last update. We’ve made some great progress and I’m super happy with having waited (although not 100% pleased with the wait, haha) because the tool has improved and we’ve tested it more. The first production run is being machined now and I’m getting ready to send some pre-production samples off to community members for feedback/reviews. I’m working on video of it in action and winding up my testing on accuracy, effectiveness, use, and longevity (all looking good so far!).

Thanks so much for the offer, I’ve worked some stuff out with them and we’re in production now, I hope it won’t be too long before tools get into the hands of others affected by stemageddon (boxgate? Stemgate? GMKquake?).
P.S. Love your cases.

Sweet… I am in!
Update:
It works! It’s happening.gif! It’s being machined now and a first batch is ready to head off to anodization mid-next week! There’s been some minor changes focused on making it work with just the tool as well as with a jig. It’s now easier to use and remove. I’m testing it now and will release the data/findings with the upcoming pre-order announcement. Hit up the IC form if you haven’t already to hear when the pre-order goes live.
Iterative Improvement
There were mostly quality of life changes like adding a handle to help with use and removal, but also some improvements to the base design (check out the original IC for more info on the original design).
- The reenforcing material on the side of the prongs was tweaked a little to make it easier to insert in the Box stem. The prongs were beefed up a little to keep the blades from separating like other tool designs were at risk of.
- The cutting surface angle was changed a little to make it easier to press down while not being too sharp as to wear.
- There was a lot of feedback about difficulty using the tool without the jig as well as removing it after cutting, so we beefed up the handle and added grooves for better grip, it increases the material but is much easier to remove, makes it easier to use without a jig, and helps with jig alignment.
- We’ve settled on anodization because tool steel was expensive and would take too much time to differentially harden and annealing that edge was tough. Anodization is key because I’m hoping to get from raw aluminum (as hard as soft steels and brass) to 50-60 HRC (about that of a knife) using a anodic type III hard coating. This is hard to describe, but it will help the tool cut and move easier as well as wear less (although wear resistance is different from hardness). This anodization should take tool life from <100 to hundreds of cycles (you can always buy more than one if you’re worried about wear, most community members don’t have more than a thousand switches and even then a tool steel isn’t economic). Type III anodization is much harder than the typical color and finish you get, for example, on a keyboard case, phone, etc. Anodizing adds 2 weeks to the process and splits up the tools into batches. Without anodization, the tool develops little burs on the edge after a couple dozen cycles that affect the cleanness of the cut while still remaining in spec (engineering nerds: edge-roll plastically deforming due to insufficient hardness doesn’t affect the cleaving walls’ dimensions but can affect the type of cut and inhibit cutting to the base of the tool).
- I’m redesigning the jig to be easier to hold and hold down on a plate for switches in a board.
- I’m designing a Nexus slider jig once some samples arrive from a generous Redditor (who I haven’t asked for permission to name – nevertheless, they’re a champ).
Testing
I’m working on several sample sets and will be releasing the data on the measurements of the stems before and after as well as leaving some ABS keycaps on pre-tool and fixed stems for some longer-term stretch tests. I’ve had to sacrifice some switches to see how error-tolerant using the tool is (it’s doing pretty well, even after dozens of cycles of misuse, the cutting edges are fine and the stems are at worst “loose”).
I’ve noticed some extra shavings in testing on the unaffected dimension that’s in spec, so I’ll try to break some of the edges that shouldn’t be unnecessarily shaved.
I’ll provide the test data of the tool in use in future announcements.
Next steps
Get ready for pre-order this next coming week! Since this is a pre-order and not a group-buy, the tools are already in production and it should be lower risk than a group buy. If you haven’t already, hit up the interest check form and I’ll email you too when the pre-order goes live.
I apologize for the occasional silence, a combination of waiting on the shop, personal loss, job transitions, and design changes have made this last longer than planned. We’re 100% moving forward with this right now. I hope to get some un-anodized samples out to community members. I will be updating with some demo videos, machining videos, progress pictures, etc. I’ll start a new thread for the pre-order when that happens, until then, keep checking this thread.

I’m still getting a better sample size (more than 100 switches) but right now, the tool is consistently trimming. I can’t promise anything, but I am planning to release the data on Cruciformer performance and durability in testing life-time. As with anything, performance of the prototype won’t perfectly match the final product, which should be better.

Great news! Have you try mounting GMK caps on box switches after shaving?
1 Like
I’m going to, but I don’t have any GMK caps on hand (always been too expensive or didn’t fit my layout).
I have some SP DSA grab bag ABS caps that are standing it, but I’d like GMK because of how much more size-sensitive they are.
How is progress so far?
I helped put the last machining finish and visual QC on them on Saturday, just working through the last of the anodizating details to make sure it doesn’t damage the edges. I’ll expect the pre-order to go live tomorrow!
There’s a couple hundred of them ready for the first batch of anodizing.

Exciting! I really look forward to this.
Will you share the link to the ordering page here?

I’ll deffo give the link here, also might make a new post.
Issues with the store kept me from opening it for orders yesterday, hope to get it out today or tomorrow.
