Notch Cutout

[madjack]

Joamon..using a jig saw...mark your cut line..use the jig saw and cut just shy of the line...use a sander to finish...if the arc is a pure radius, you can make a circle cutter outta a 6"x3' piece of ply or masonite that is 1/4"thick or less and use your router to cutout the notch

Since I used 1/4 inch strips glued together to form our wall frames, I plan to just add 3/8 strips of wood to our frame and leave off at the hatch, thereby creating a notch. This would be the easiest for me as our frame work is 1 1/2 inch thick.


Another question, since our sides will be 1 1/2+ thick, would it be better to have two weather strippings instead of just one, or would this cause problems?

..2 weather strips...I dunno, it might seal up so tight that when you openned it, the "back" pressure might cause it to "pop" open and hit ya in the chin ...long as ya left 1/4"(or so) between them for the compression to expand into, there should be no problem

naw, two weather strips are not necessary.

Pick the style that goes best with your teardrop and run with it.

Thanks Mike and Jack, I guess I will stick with one weather strip then.

What would be the best way ( or some ways) to cut this notch on a tear that is 50 or 60% built? I supose a router with a guide but I don't have a guide. I have alot of tools just not a guide for my router. Maybe I'll have to buy one.

If I decide to cut the notch, I plan to do it with a router. First I'll follow the curve of the area to be notched with a rabbit bit in the router (only problem is the rabbit bit I have cuts a 3/8" rabbit). Then go back over the same area with a pattern bit (top bearing). This should perfectly follow the imperfect curve that I originally cut with the jig saw. What more could you ask for...perfectly reproduced imperfection.....

The notch will then be about 1/8" too deep but a bit of aluminum flat bar should cure that problem easily enough.

We are coming along on the little tear pretty good so far with all of ya'lls help. I cut our notch like Larwyn said he was doing with his router. it worked great. My question is, will 5/8 inch be wide enough, if not I can cut it a little wider.
