Removing Quickchange adaptors

[karossii]

I know this is (very) late in the game to most people... but I have my 11 piece decorative bit set I got with the original purchase of my B machine. And I need to remove the adaptors to use the 60 degree (and maybe 90 degree) v groove bits with some centerline text.

I tried using a T-10 (I think) bit in a screwdriver to unscrew one or both of the side set screws. They weren't budging. I came here and did some searches, and reminded myself of the solution to bake them for a bit, then try again. I first tried 10 minutes at 400 degrees. Not any help. I then tried 15 minutes at 425 degrees. Again, they were still locked tight.

Are there any other things I can try to help remove these screws? Hard to find any advice since all the chatter about it is so old now.

I used a set of brake pliers. Some were easy and some were a bear. Some you just need a good bit of leverage.

I used a plumbers torch to heat mine up in a shop vise. Some of the heads in the set screws stripped out so I had to use some small vise grip pliers to remove them.

If you have a drill press you can press the bits out after heating. I cut the head off a small screw/bolt that was just a tad smaller than the 1/4" bit shank. Put it in the drill chuck and place the CW bit in the center hole of the drill press plate. MAKE SURE YOU PUT SEVERAL SMALL RAGS UNDER THE BIT to catch them as they drop out of the adapter.

I don't have brake pliers, so that option is out. I also don't have a small torch, so the oven is my only real option for heating it. Or a grill, I suppose...

I could pull it out of the oven and put it in my drill press... will it not harm the shank to just push it out past the set screws?

You will need to remove the set screws. Got some vise grips? https://www.google.com/search?q=vise...w=1093&bih=519

I do, several sets of vice grips... not sure if I have any small enough for that though. Will have to dig through them all and see.
