sdt354 had a CPU failure also so he lost his info as well. The only difference in my method and the Youtube vid is I soak slides fully submerged in WD 40 overnight to loosen glue. Then instead of using a screwdriver to knock slide loose from diaph. holder, I use a deep well 3/8 drive socket with a 6 inch extension attached to socket to drive the slide loose from diaphragm holder instead of a screwdriver which is where most people's failure comes into play. When using a deep well socket inserted into slide, you get even forces 360 degrees around the slide instead of just a sharp screwdriver which will inevitably break the brittle slide component. I don't remove needle from slide because using a deep well socket fits over the screw (needle holder assy) inside the slide. I also use a metal pipe, which happened to be the top rail of a chain link fence I took down and cut off about 6 inches of pipe that I insert slide into while I drive slide away from diaphragm holder. The bottom of pipe is stuffed with a single paper towel to soften the fall when the slide drops from diaphragm holder. I use a very small hammer to tap slide loose from holder, usually with a couple of small taps you can see a gap between slide and washers and the rest can be done by hand to finish disassemble. After disassembly I take the aluminum holder to the bench wheel and clean glue residue with wire brush side of grinder, you can also use a piece of fine sand paper to clean glue reside off. After you get holder clean the use a fine piece of sand paper to clean residue from inside the slide, ideally you want to be able to push holder into slide with very little resistance. Reassemble slide and new diaphragm making sure washers are all facing the right direction. Use oil or petroleum resistant glue of your choice to reassemble. I use Devron metal filler glue which dries in 45 seconds so I have to work fast to have everything in place fast. After applying glue (to aluminum holder only) I insert the holder into slide by hand, making sure it is going in square and not the least bit crooked. I then place slide on a solid flat wooden surface and with the same deep well socket I used on disassembly I place it on the bottom side of the slide and give it a couple of small taps to tighten up washers around newly installed diaphragm. I then use a small screw driver to clean away any glue residue that may have oozed out. If I had pics I would post them, but unfortunately Steve and I both lost the info with a CPU crash.
