Based on discussion here Redline Spindle order status - #26 by RJensen with @RJensen and @kenmachdata I made up a 80mm to 69mm router shim/sleeve/spacer with the inner radius offset from the outer to (hopefully) allow a Dewalt 611 router to fit in the spindle mount without having to shave the router down any.
As I do not yet have my 1F, I can not verify fit. Currently the sleeve is 50mm tall from the underside of the lip, and the lip is 4mm wide. If these need adjusting I will do so.
Here is the STL file for anyone who wants to print one.

Thanks for posting this. I will be watching this post and see how it goes. I can’t afford the time to take my cmc down to help test this. I hope to get my spindle in the not too distant future so if I do when I take it down for that change, I’ll be testing this. Thanks and I hope we all get spindles soon so we can chat about that.

I don’t see how your adapter wouldn’t need the same shaving of the top of the Dewalt router. You are reducing the diameter from 80 to 69, so the edge of the router body is 5 1/2 mm from the edge of the spindle/router holder. I don’t know how your adapter would not have the same issue with the label or warning label on the router from rubbing against the Z-20 slider. The part of the router that is too big is above the adapter. Am I missing something in your design?
The 69mm circle is pushed way to one side of the 80mm diameter, not centered. Idea being to move it further forward, away from the carriage assembly. Got the idea from that prior thread. Not sure if its enough to clear it, but its as much correction as is possible in the limits of the 80mm mount.
And like I said, I dont even have one here to measure against or try it out. Im just reading along and putting my tools and skills to use best I can until I do.

Sorry, I missed that. Clever design. I’d be interested in buying one to see how it works. It may also address a slight issue I have with my dust boot.

Top view shows it better. That thin side is 3mm, if needed to make the clearance it could maybe be thinned down to 2mm

Buy? Beta testers don’t buy things. They DM people an address and pay shipping. Especially since I don’t even know if this will work.
First one is running right now, it’s in white because that’s what I already had loaded in PETG.
