Hi all, I'm new on here so thanks for adding me. I've had a look around the site but couldn't find an answer to my problem. I'm restoring a Wadkin AGS 12 saw and the pivot pin on the rise and fall mechanism is well and truly seized. I've removed the grub screws, sprayed it in wd40, applied heat to the casting, tried hammering a brass drift pin in, tried pushing it out with a bridging block and a g clamp, but absolutely no movement. As a last resort I could drill it out and get a new one made, but I'm hoping someone will have experience with this and have good suggestions. Thanks guys.
