•Pop off the leg at the thigh swivel and use the cutting disc to remove the peg. You can hold the cutting disc on its side to make the surface flush if needed, or just use a file.

For this figure specifically, don't cut off the raised circular part.

•Use the grinding bit to carefully create a cavity where you can securely plug in the pin's stud. A snug fit is best.

•Test fit the parts. If there's a little gap at the swivel, shave down the raised circular area on the pink hip piece a little bit at a time until the gap disappears.

•Once the fit is to your liking, super glue the stud into the cavity.

DO NOT glue the pin, that part goes into the thigh. The bottom right picture is just there to show you how deep the pin goes into the thigh.

•Once the glue is dry, test fit again. If the swivel is too loose, stuff a little Apoxie Sculpt in the thigh's hole and smush it around the sides. Try not to get clay jammed up the center of the pin.

•Press the parts together so they're flush, then use a twisting motion to mush the clay around. While this is hardening, use the same motions every hour or so to keep the clay from locking up the pin.

It's a good idea to use a quick-hardening clay, that way you can just keep the parts pressed together and twisting for like 5 minutes and be done, instead of waiting hours for apoxie sculpt to harden.

Once that's hardened, pull off the leg and it should pop off with a little effort. If there's too much clay inside the pin, just drill it out carefully. What you want is for the tips of the pin to flex a little, this is what lets it hook into the thigh securely while still letting you pull the leg off when you want.
