@Cheese Thanks, I had to change the avatar, as it was causing unrest in the grand kid camp (favouritism)  [doh]

Your test showed more movement than I imagined, I know there will be some but, that's an eye opener. I suppose it could also work the other way round. Like some that have had the misfortune of the slop or play in their Parff sticks, yet test cuts showed them to be square?

I wonder if, and how much play there might be with a CNC?

Is MDF the best material for making a table like the festool MFT table? Oner picture on the thread looks like melamine covered MDF.
Thanks

Don’t know which bushing is required by the Woodpecker jig but the Festool 20mm bit does work in the Festool OF 1100, and 1000, and 900 too.

Woodpeckers uses 2 different proprietary bushings along with a 1/2" Ø router bit to produce either 20 mm or 3/4" Ø holes. So while the Festool 20 mm bit will fit a 1010 router, the Woodpeckers hole boring jig system is centered around using a 1400 router, or equivalent that will accept 1/2" Ø bits.

Does the Festool 20mm bit work with the Woodpecker bushing? Maybe that’s what you ended up using and I didn’t read carefully enough.

It works wonderfully...it's just that you need to make a bushing for the Woodpeckers bushing.  [eek]





Personally, I'm surprised that they decided to release it as a regular part of their product line. In my mind it's still in the development stage and should be offered only to experimenters. It's not a very elegant solution to produce either 20 mm Ø or 1/2" Ø holes.  [crying]   [crying]

Cheese you're making a straight plunge but that doesn't take the movement of the bushing guide plate snapped into the base of the 1400. That potential movement is still there,, and even though you are now not applying lateral force to it there is still the possibility that it can (or WILL) move when withdrawn and placed in the next hole in the template.

It seems to me that another brand plunge router (PC690/890, Milwaukee, DeWalt, you name it) that has a fixed base and uses PC style bushings would be a better choice along with your adapter bushing to eliminate any lateral movement.

I have a OF1400, and at least 6  other routers. But after seeing what you have shown us all with your tests I will never rely on the OF1400 for accurate guide bushing work.

I agree 100% Bob... [thumbs up]  That's the reason I rely on the 1010 for all of my guide bushing work. Sometimes when you go down one of these rabbit holes it's a good practice to just take a breath and think for a minute. Note to self, I really should have fabricated a guide bushing adaptor for the 1010 instead.  [doh]

However on a larger scale, had I known what I know now, I'd have purchased the LR 32 system instead as I already have a holey rail. I would take the $190 for the jig, $60 for the Whiteside 1/2" bit, and $70 for the Festool 20 mm bit and apply that to the cost of the LR 32 instead. I'd then have a piece of kit that was more than just a one-pony show.

I exchanged several emails and photos with Ed from Woodpeckers and he confirmed my results. It was in one of these exchanges that he stated that Woodpeckers was recommending the jig for hold down purposes only...not to be used for precision alignment or cutting.  [eek]
