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.

I have two of these for anybody who wants to test them out. One can be yours for the cost of shipping.

Very Nice!
I might suggest that you that you move the slot 90 degrees clockwise. This would line the slot up with the clamp on the Onefinity. I have a DeWalt router. This would be something I would be Interested in. I loaded the DeWalt into my Onefinity just to make some dust while I wait for the spindle. It is way out of tram!!! But I did cut a circle into MDF. That was satisfying.

something I had not thought of when I first drew it up. Though I wonder if it matters, the split is not so the sleeve can compress, it is already the minimum diameter. The split is to allow it to EXPAND slightly so you can get it on the router.
Easy enough to tweak the model and print another if you really want one though.
I have been hoping my spindle would arrive close enough to the machine to not need to do this, but at this rate if I do I will go with the harbor freight router as a temporary measure.
I hadn’t considered the tramming issue either. I thought that would be part of their original setup process and part of the reason for their long lead times. Stands to reason though that your router in an adapter sleeve doesn’t tram out the same as whatever spindle they used for initial setup. Which also means if you tram it out with the router/adapter, you will have to do that yet again when you get your spindle. Ugh…

The movement of the slot is based on the same principal of aligning the slots on a collet reducer. IE 1/4 to 1/8 I would align the slots so as the collet squeezes down the insert also squeezes the bit shank. My major tramming issue is do to the Router head hitting the Z slider. I too dread tramming twice. But it would be nice to use the DeWalt as a backup. With small bit projects the tramming would not be such a big deal. With the 1 inch flatting bit it really showed up. Neat pattern though. Maybe someone could work up a tilting Z slider. I use to work for a small router tool company called WoodHaven. He had a tilting router base.

Sorry for the delay in responding. Sometimes life gets in the way of having fun! Yes, I think I would like to try this out. I just got an email responds from OneF. Not the best news, seems Spindle will be pushed back to April. I would like to do more then just move the Z around. I would like to try some of the Carveco files I have setup, they look good on the preview.

Here we go. I rotated the split 90 degrees, made it only a 10 degree radian instead of 20, and reduced the narrow side from 3mm to 2mm. Printed in DeWalt yellow PLA. PM me an address and I’ll send both of these for cost of shipping.

Just looking at your picture. I think the slot is on the wrong side. when looking from the front of the machine the clamping screws are on the left side. As pictured, putting the lip on top, would put the slot on the right side. As pictured you could make it work by putting it in from the bottom.

I made a straight adapter when I got my Foreman and had to shave down the Dewalt. I would recommend getting rid of the lip. I have one on the adapter I made, and I put the lip on the bottom to get a bit more z depth.

Excellent point. I suppose the lip is only even necessary for a few seconds until you start to tighten the mount.
I saw this after already boxing the pictured print up for @Dustbuster, but I’ll tweak the file for any future uses. What is the actual height of that front half of the clamping mount? I’ll also shorten the sleeve up to only be that tall.
The little detent at the top of the one pictured is a nice touch, how it keys in to the router at that spot. But with neither a router nor a onefinity in front of me those would be hard details to add at this time.
Here is latest iteration

I just went out to the shop and measured the height of the sleeve at 45mm.

I was reading back thru this tread. I was confused by your comment about a detent. That picture of the router in the Z slider is mine. The yellow plastic of the router Is detented to the metal lower part of the router. The gray showing below the router clamp is Duck tape I used to shim the router to 80mm. We have a saying around here “If you can’t fix it with Duck tape you probably need a new one”.
