Another OF1400 where the collet and centering guides do not line up...

Now- I've almost exhaustively researched and read all the posts on this- but I'm reaching out here because I am hoping this idea might be a good solution that is a little easier to deal with- for those of us not interested in completing a crash machining course on our pricey OF1400's.

The TL:DR version of this is that the OF 1400 does not allow for adjustment and has minor deviations when using pattern bits such as those by Porter Cable or Amana or any number of manufacturers. A youtube video solves this by swapping out a base that matches the router and allows for centering the pattern bit, tightening it down to the base. I'm trying to find a version of this for the OF1400 since it seems like the best solution since Festool didn't allow for a precise method of centering the base to the mandrel.

The issue:

When using a template guide with the included attachment for your OF1400 (not everyone's it seems, but a LARGE amount of us), there is no method to center the mandrel/collet/router bit (what have you-) with the pattern guide. Additionally- there is slop within said guide to the degree that it could lead to variances when following a pattern such as with a dovetail guide, a general pattern or something such as the woodpecker's bench dog boring guide. A user by the name of Cheese illustrated in a post of this topic a very detailed description of how much it was out last November. Various other users have agreed that this is an issue with their OF 1400's as is the case with mine which I discovered today after about a year of ownership. (said post is here)

Festool responses have been sparse and I've only actually seen one user comment their actual response was something along the lines of (and I am paraphrasing) 'It's not a tool defect. User modification would be required for perfect fit' with reasoning as it was a trade off they (Festool) opted for in efficiency of production or something along those lines. Regardless- while I do feel the reason that user was given is a cop-out for something they didn't choose to address, I still really do like this router and all of the Festool items I own.

Possible solutions: Widen the holes that the attachment fits into- that works except there is some finesse required to do this well, and cleanly, and you still have the problem with the slight play from the guide being held to the router with the quick release clips. The solution I am after which sounds like a significantly better one is from this youtube video from 2009. The only issue I have is that I KNOW, this being Festool- they will have their own set of holes that won't play so nice with others, and I was curious if anyone knew of a brand that made a base that would come pre-drilled for the OF1400 which would accept the Porter Cable Pattern bits. I've tried looking for a few- but it seems none include pre-bored holes for Festool and my best bet would be to buy one of the universal bases and carefully use a drill press I have access to for boring holes that would work with the Festool router and possibly locate the correct screws which would allow the fine-tuning adjustment I'm after for centering the pattern jigs.

Any advice/solutions etc is very welcome and if you made it this far- thanks. It's 1:30 am and I am a bit tired so some of my post might... not make much sense, but I really wanted to get this out there before it all slipped my mind with work and everything else going on in this crazy world. I no longer have an immediate need for the accuracy I'm after with this particular situation (I made do for now), but I do have a need in the future and I'd like to be prepared rather than have the issue arise again on a tight schedule with no way around it.
 
Would the Trend sub base for the OF1400 be good enough for you?
 
It looks like it's possible- I can't tell- the only one I seem to locate is on the woodcraft site- and it just says "most popular routers". After sleeping on the issue, I'm really thinking about going for the Jasper baseplate or one like these. The clear base is exceptionally appealing for ease of sight, and if I really need to drill out larger holes and countersink for pan-head screw heads, I can do it since I do have easy access to a decent drill press which is easy enough to alter the speed on.

It's a bit off-putting that there are so many forum pages on this topic, and so little official response from Festool and concurrently so few people who brought this solution up of using a baseplate pre-bored for the Porter Cable pattern bits unless they just lost interest or forgot to post their solutions. I suppose using those pattern bits is a bit specialty- I didn't notice the fact that things were off until after a year of ownership, and with so many people who also use bearings on their router bits- it's sort of a niche kind of use it would seem.
 
That's okay- I appreciate the input. Also need to try and find something easily available in the US since that's where I am and I have absolutely NO idea how things are going now days with shipping.

On the upside- I located someone in my city really close by who is apparently a master machinist as far as most things plastic are concerned and has excellent Yelp reviews. I may get in touch with him about fabricating a base plate for my router to see how that goes if it's a cost-effective alternative since they're maybe 2-3 miles (3.2-4.8km for you others) away from me. It certainly seems like a good idea over having to buy and fabricate the plastic/polycarb base myself which would entail also purchasing a good forstner bit to match the pattern bits I have etc etc. If it's able to be fabricated and works well, I may have a second one made to keep both as backup/master template for recreation in case others decide to look into it. Definitely a side project for now though.
 
Here's a router base from MicroFence that can be used on a Festool guide rail. I drilled this router base to fit both the 1010 and 1400 routers. Depending upon what your needs are this can be used on a Festool guide rail. I believe the yellow dots are for the 1400 while the red dots are for the 1010.

Just make sure the thru-holes are a titch larger, the counterbores are a titch larger and make sure to use cheese head screws.
