Kinda looks like a solution in search of a problem. Or maybe it's just that I'm only on my second cup of coffee... ;)

Well that's different! :)

I've never even considered something to hold the ejector down. I modify as necessary to get the ejector to sit nice and flat on the frame, then I mark the front pin with a little tool I made our of O-1 tool steel. The marking end is cut at about a 30 degree angle, so when I insert it in the pin hole and give it a light rap it leaves a nice bright mark on the front leg of the ejector.

I then simply use a needle file to cut a slot in the front leg that is offset slightly high. This insures that when I put the ejector pin in place, it literally pulls the ejector down onto the frame.

That's if I even bother to pin the ejector. ;) :D

Hi,
Hmmm...Here's my ejector pin jig being used with a 1/16" 4 flute end mill.
I am going to try the end mill idea next time!

I've done this stuff the same way so long, it's hard for me to change my method to achieve the same objective. Or...

It's hard for this Old Dog to justify New Tricks? ;) :D

Hi,
Does not matter, what ever works that you feel comfy with.
I looked at filing the leg and even the left hand drill trick.
Decided to use the end mill cause I liked cutting, better than drilling.
Be advised, if anyone does use the end mill, better have a light touch and give it time to cut!!! Ha!

True that! How fast do you spin that little endmill?

Hi,
Only about 650 or so and I also use air to keep the chips clear.
Seems a HSS drill bit might want to walk???
That carbide end mill won't walk, but it is of course fragile and needs a soft touch on that Bridgeport!

I'd be spinning that little end mill at least 3k, maybe 4k to keep the chip load down. And my FogBuster air/coolant to keep things cool. :)

Hi,
Well, Carbide does like high speeds...
But, I've had no problems, maybe cause there is not a lot to cut?
