Festool Guide Bushing Adaptor issue

[gotallie]

I have a problem with a Festool accessory that no one at Festool appears to be available to answer.  Perhaps someone here will be able to supply an answer.

The accessory is a Guide Bushing Adaptor, p/n 469625.  It is described on the Festool site as “Accepts industry standard two-piece threaded guide bushings”.  None of my “Threaded two piece Router Template Guides” will fit into this Festool adapter.  This includes the Bosch and Porter Cable brands.  If the Festool product is not compatible with those two brands which are interchangeable in all of my other routers, then what brand or type of bushings does Festool define as “industry standard two-piece threaded guide bushings”?

Mine work with it.

Same as with Tom: mine work fine.  I've used it with PC bushing, a Woodcraft-branded one, as well as two different Leigh bushings.  Work great.  What is incompatible about it? The bushings not insert in the hole?  Was it mis-machined or maybe the wrong product?

I have the same adapter, and so far have only checked my Whiteside inlay kit bushing.  The threaded part won't fit inside the adapter, and I have not had this issue in any other baseplate (dewalt, porter cable, woodpecker).  I was going to check out my full bushing set over the weekend.

I will note that this problem has been mentioned before, but to the lesser extreme of not having the bushing centered, and one solution was to file down the threads on the bushings.  A second approach was to pull some alignment pins in the router baseplate.  These also gave enough room for the bushing to be centered relative to the bit.

The original part number mentioned is for the OF 1010 router which is a different design in plastic than the metal ones for the OF 1400 in those threads.

I have the part, and just as PaulMarcel and Tom, I don't have a problem with the UKJ bushing set which I believe is a standard PC size.

Do you have a vernier gauge gotallie? I measure the inside diameter on mine at 30.24mm, which is 1.19 inches. I understand the PC bushings are 1 3/16", or 1.1875 inches, so they would just fit inside this.

Perhaps yours measures something different and has maybe been machined incorrectly and this is causing the problem?

 

[tbellemare]

I kind of doubt that this part is machined since it's a plastic part. If I'm correct, they all came out of the same mold or mold design.

Something seems odd about anyone not being able to load their PC style bushings in any of these, whether the 1010 version or the 1400/2200/MFK.

Tom

EDIT:
Is the bushing squashed and therefore, not round?

 

[GarryMartin]

Agreed. I guess "machined" isn't the right word in this context. Moulded incorrectly perhaps?

 

[gotallie]

I assume that the part is correct as the part number is molded onto the adapter.  

The issue is that the bushings do not seat into the adapter.  The recessed opening is too small to allow the template guide to seat after the threads have passed through the opening.

The adapter opening reads about 30.2mm.  There is a shoulder below the bushing’s top plate that measures about 30.5mm.  This shoulder will not pass through the opening to allow the bushing to seat flush.  I can turn the bushing upside down and the top plate will seat perfectly albeit with a little play.

This shoulder is not a problem with the bosch or porter cable adapter rings and appears to actually allow the bushing to center without play.

 

[tbellemare]

I just got out my caliper and measured the one shown above.

The through hole is about 30.1mm diameter.

The counterbore where the bushing seats is about 35.1mm diameter.

Perhaps a photo would help. Are you able to post one showing the problem with he shoulder?

 

[Stoli]

I just noticed we are talking about different parts.  I have an of1400 with the 493566 adapter.  I'll start a new thread with my measurements.

 

[gotallie]

Here is the photo.  The red arrow points to the shoulder.  I solved my issue temporarily by buying a cheap brass set of bushings.  These are not self-centering and require a centering mandrel.  Not near as nice as my other bushings but this way I can at least start the project using this router.
Thanks for all of your replies.

 

[Kevster]

I just bought an OF 1400 router yesterday and had the same problem. The threaded part just misses fitting for my jesada guide bushings. My Leigh guide bushings just fit when inserted with a little bit of "finesse".  I figured I got the one bad apple until I saw this posting.

I guess my question still stands: If the Festool product is not compatible with those two brands which are interchangeable in all of my other routers, then what brand or type of bushings does Festool define as “industry standard two-piece threaded guide bushings”?

I think that Festool should remove the "industry standard" from the description or list compatible bushings.  Apparently the "standard" is loosely defined.

The problem is with the PC system being an "industry standard". It is a quasi industry standard. I have yet to see any specific dimensioning for the PC system that defines the exact sizes of the thread OD or the pilot OD above the thread. I have read many posts here and over on Sawmill Creek where a poster says there is too much slop between the thread and the adapter ID, or between the adapter pilot diameter and the bushing pilot diameter. Or conversly, there is interference and the bushings cannot be seated properly. The problem is there are any number of folks making adapters and bushings for various routers and applications without any clear 'standard specification'. One guy measures the original and makes his product that size, or some facsimile thereof with maybe a few thousands more clearance just in case, and after a few thousand iterations things begin to go awry.

I believe the original design intent was for the pilot diameter above the thread to be the defining feature for centering, or at least it should have been because threads make for poor location quality. But, imitators don't always know that and if they use the threads for location they tend to ignore the adjacent pilot diameters. Poof! Nothing fits right anymore. My suggestion is to measure components on the pilot diameters until you get a set that fit correctly. Festool made their PC adapters to fit something. If you can find them you will be good. I have a set from Rockler that fit my Festool adapters with about .001 or .002" clearance, so I am happy. Wishing you the best of luck.

Is this part (469625) only available from the States.I have done a search and cannot find a uk supplier including Festool Uk? Thanks

No, you can get them worldwide as a spare part.

The part number for the OF 1400 guide bush adapter is (or was) 493566 but that does not appear in the search results on the Festool UK web site. But if you go to the Toolfest web site and do the search you find the item - here is that link:

With this adapter you can use all of the UJK guide bushes.
