My boat is a woody, but it sounds as if your sliders are captured and held in place by the wooden frames. Here's what I did a few years back to replace a cracked slider: 1. Slide the window open about 1-2 inches. 2. Use a grinding wheel to vertically cut the top of the frame inch ahead and one inch behind the slider. 3. Sand the paint off the wooden frame between the two cuts to find the wooden plugs covering the screws attaching the frame to the cabin side. 4. Use a Forstner bit of whatever else you like to cut the plugs and then remove the screws. 5. Use a chisel to break the glue/sealant bond between the frame and the cabin. If you destroy the bit of framing, it's no big deal to form up a new one - mine popped off. Do not use something like 4200/5200 to reattach it unless you are ready to employ Debond liberally and hopefully. 6. Lever the slider down from the top and pull out all the old window channel material. 7. Place new channel in the bottom and side frames. 8. Put the new slider in place and seal and refasten the top piece of frame in place. 9. Working from the "back" end of the slider, you should be able to work the new top window channel material into place. Put a couple of screws through it into the frame to hold it in place before sliding the window all the way aft. Then put a few screws through it into the frame to hold the front end of the channel in place. 10. Fair the cuts and repaint. Yer, dun, bud. :) Rich Gano CALYPSO (GB-42 #295) Southport, FL (near Panama City)

I am not sure I am getting a good mental picture of what you are describing. Can you come over and do one or two (or more) of mine so I can watch and see how to do it? ;) -- Ken Tischler Microship DeFever 49RPH Bay St Louis, MS On Tue, Apr 26, 2011 at 9:55 AM, Rich Gano <richgano@gmail.com> wrote: > My boat is a woody, but it sounds as if your sliders are captured and held in > place by the wooden frames.
