You just cut off two of the teeth from a 28 and you'd have a 26. I'd recommend cutting off two on opposite sides from each other.

3D is still new tech, one thing that seems to occur with modern tech is each generation gets cheaper, so it's $150 today, 5 years down the road it might be only $15, and 10 years down the road, it might be 15¢ Although realistically a better way to do cogs, might be to stamp cogs with a blank centre, then uses CNC to clean up and cut the centre might work better and be cheaper.

3D is just out of the question in my lifetime. Powder metal has its uses too but very limited, 3D is worse. Tooling for stamping small volumes is out of the question from a cost perspective, even in China. CNC with what? Can't use an end mill to make square corners so it would have to be broaching or a very small second or third operation with a very small radius mill. Most cost effective would be laser or water jet if the later will cut through the thickness of a cog without leaving slag and a rough edge.
Am I missing something? I am not a machinist but have some exposure to manufacturing process and tools. Is there any machinist or industrial engineer out there that can help?

Funny, I had this same thought (the dearth of good freewheels in with ranges I want) on Sunday. I'm almost ready to toss in the towel and switch my McLean to a freehub and indexed gearing. It currently has Campagnolo Nuovo Record derailleurs and hubs. It has a 14-28 Shimano freewheel which is starting to make noise while pedaling. I think the chain isn't meshing well with the teeth on the freewheel. I'd like a higher top gear, i.e. 13T smallest cog. The 28T cog makes noise because I'm pushing the limit of the RD, resulting in the pulley, chain, and cog all being squashed together. So ideally, I'd like a 13-26 7-speed freewheel. Do they exist? I would settle for a 6-speed, I suppose.

Looking at a 7-speed cassette I have here, the splines are far from perfect, it's not the most precise thing I've ever seen. The important dimensions to match would be the minor diameter and the edges of the splines. You could probably do it with EDM or water jet. The big problem is the enormous variety of freewheels and limited number of customers.

I did it again. Just bought an Italian-threaded 15t-25t Everest FW for $16. My resistance to buying superfluous bike parts is futile. Between the 10 or so that are installed and about a dozen spares, I think I'm good on FWs for at least the next decade.
Guilty as charged!

@Darth Lefty - Thanks! I sold CAD/CAM/CAE SW for a short period of time and we were using and selling 3D machines back in mid 90's. Great for marketing, no good for usable parts.
So what is the most popular freewheel hub that would be a candidate as a "standard" for modified freehub cogs?

What brand freewheel and what range? The reason I ask is if the internals are maintained, the cogs can potentially be replaced.

Seems to me that there's a future reserve of mid/wide range 7 spd. freewheels on all the Kent bikes etc. being pumped through the big box stores these past years. Not high end, I know, but they seem to function, at any rate, and sport modern, twisted tooth design.
I have one in use, giving good service, and one removed due to non-preferred gearing, in my stash somewhere.

Yep, I'm planning to stay on top of that. It's an Atom 77 6 speed. I believe it's 13-24, but I'll have to double check when I get home. I figure worst case scenario, I can get an english threaded one and transfer over the cogs.
