Hi mftha,

The closest that OP has to a 4" opening is their plate used for large bits & raised panels. It has a 3 1/8" opening, unfortunetly, if you're wanting to get bushing guides that large, you'll have to machine them yourself or have a machine shop do them for you. Preferrably from brass stock.

Sad truth is, unless all State Senators are informed for the push to (as Harry calls it), "metrication". It won't happen. Thus how things are now, a mixed batch of metric & SAE sizes.

Hi Guys

Not to hard to make your own ,,,(bushing guides out of plastic that fit over the standard brass guides or to say on to the brass guides) and the one Harry and Tom like to use the 40mm one is showed in the link below...

Just a note about the OP plate that has the unstardard 3 1/8" hole, it's not a big job to resize it to 3 3/4" hole so it can take on the stantard 3 1/2" panel bits...
Without the resize job you can't use many of the better panel bits that are 3" to 3 1/2"..in diam.

Thanks for the tips there. I really like your sanding jig too!!

You by chance wouldn't have a pic or two of a "modified" OP plate?

Hi Ken

Thanks and you'er welcome

Here's some shots of the reworked OP base plate..

======
I used the fly cutter below to open the size to 3 3/4"
Not a big job but it must be done on the drill press and clamped in place.

Hi Bob,

Yuuup!! Already got a friend who wants me to build a small cedar chest, something like the size of 2' X 3'. Figure a 4" hinge "wood" work. LOL Not sure how deep to make it, prolly 18".

The problem for me right now is, finding the time, work seems to always interfere. But, gotta pay bills.
