Lowes only had 6-32 x 3/8" brass screws, which means they protrude into the air stream. Still contemplating ordering some 3/16" screws...

Seems slightly undersized, but I'll run it like this and see what the idle is like. If it is leaking too much air, I'll make a bigger plate

Mark the mounting screw locations, remove the plate a drill oversized holes.

Lowes only had 6-32 x 3/8" brass screws. Still deciding on whether to keep these or order some 3/16" or 1/4" screws.

It seems like there's a slightly bigger gap than stock, but I'll see how it idles and remake the plate if needed.

Reinstall the plate, doing the 'open, close' routine a couple of times to center the plate.

Open and close the valve several times and it should self center and seat. Mark the hole locations in the plate.

Keep track of how much you take off. Don't want to overshoot. Measure often.

Find the exact center of the bore (VERY IMPORTANT). See here to learn how: https://youtu.be/VY2crpjhL3E

This gets mounted in the vise, then a 59.55mm diameter circle is cut, and I end up with a perfectly machined and sized butterfly valve for my 60mm throttle body.

Width of the slot, so when I cut my new butterfly valve plate, it needs to be .060" thick.

The slot is wider on one side than the other (this side is 52 mm while the other side is wider). Forces the plate centered in the bore.

There are bearings in there that the shaft rotates on. If you're doing anything to the housing, make sure you thoroughly clean them out and grease them before reassembly.

When the throttle/butterfly valve plate is closed, it sits at a 16deg (8 on each side of the center line) angle off of perpendicular to the axis of the bore. This means that the width is the diameter of the bore (previous photo), but will be wider on the other axis (becomes an oval)
