Topic tags/keywords: question

Hello all,
I just got a pair of wood doors back from the stripper and they are in very rough shape. First order of business seems like replacing a plywood panel in one of ther doors (see picture). It delaminated and rippled in the striiping tank. It is (I believe) beyond repair. So, I can make a new panel, but, how do I disassemble the door enough to replace the panel? There are no visable fasteners or dowels. Although I may be able to use a clamp set up as a spreader along with a heat gun to disassemble the door, I am only guessing. Any experienced advise will be helpful.

thanks all

1) I would evaluate an ovelay panel
2) bandsaw the bottum rail out right at the sticking line. (cant tell your profile from pic.), insert new panel then spline or dowel the rail back in position.
Good luck with it.

On the other hand you can remove the bottum panel easy enough than install a stop of sorts, install panel then use applied mollding on both sides.

Unless it was assembled with hyde glue, which is unlikely unless it is an antique, you are probably going to have a difficult time getting it apart. The old hyde glue would come apart with heat and steam, but newer glues will not. If the joints are loose however, you can tap the apart with a mallet and block, or even with a clamp as you suggested. Don’t be suprised if the wood spinters and breaks within the joints. Be very gentle.

Slice it at the rail joints with a bandsaw, remove and replace your panel and put it back together with floating tenons or thick dowels.

if the door has blind mortise and tenon joints then it probably has internal wedges as well…which means it won’t come apart….look under the bottom rail for any telltale signs …there may be signs where it has been haunched….if so then slice the bottom rail out hopefully the panel is floating. you will most likely have to replace the bottom rail as well because it won’t pull up parallel again.will also mean cleaning out the old mortise joint so you can slide in a new rail. then just glue in a filler block on the bottom of the stile sand it up it it will be as good as new
we have had to replace panels in our gates and that is how we do it….i have done it with doors as well.

-- just get stuck in and have a go!!!

Sometimes when dip stripping doors the joints can become loosened during the stripping process. First check and see if any are loose and need to be re-glued. Chances are the joints were done with cope a stick joinery and dowels. Here are some steps you can take to help loosen glue joints so they can be re-glued.

This comes from wood central:
Hide glue can be “de-activated” on joints that are still stuck by saturating the joint with alcohol. Squirt some alcohol (I use denatured alcohol) along the edges of the joint and it will wick in by capillary action. After several minutes the joint will be loose enough to pull apart.

PVA glues like Titebond and Elmer’s are very difficult to remove. If you suspect that one of these glues was used, wetting the joint in hot vinegar loosens the joint enough to wiggle it apart. Unlike hide glue, PVA glue does not re-bond to itself so you must scrape off the old glue to bare wood. If you are gluing a broken piece of wood with irregular edges, soak the glue with hot vinegar and remove it with a brass bristle brush.

If you’re not sure which glue was used you can do a simple test. Place a drop of hot water on the glue and wait several minutes. Hide glue will become sticky and PVA glues will turn white.

Other glues you may encounter are epoxy, urea-resin and super glue. All of these glues should be treated the same as PVA in that they are non-reversible. However, none of them can be softened to aid in disassembly. Since most of these glues are brittle, a sharp blow with a hammer usually breaks the glue line.

I would try to remove one of the stiles very carefully, replace the panel and glue it back together.

I took an old door apart. I removed the glass then started pushing it apart with clamps. It had hand cut dowels in it. I took it all apart and replaced some broken dowels. I just took my time and made spreader clamps to open it up.

Unless you have a really special door, it probably won’t come apart without a lot of aggravation. Most doors are built to go together but not be taken apart. Panels are usually done the same way as cabinet doors – the panel sits in dados in the rails and stiles.

If the only problem is the panel, you can probably use a router to cut away one side of the rail and stile dados that hold it in place. Pop out the bad panel and install a new one. Replace what you cut away with some new molding.

What sawkerf says. Rout out the cope and bead on one side, drop new panel in and trim out with new sticking stops.

Thanks everyone – I have decided to “Rout out one side, drop new panel in and trim out with new stops”. It sounds like a plan to me. Thanks for the help.

That’s just how I’d do it, stcin.

But make sure you are routing out the same side of the door that the glass bead is on in the glass opening.

As Sawkerf, tblank and tbone suggested I did use a router to cut out the old panel. Using 1/8 birch ply with some figure on one side I glued two 1/8” panels back to back so figure would show on both sides of the door. Then made trim to retain the panel and reinstalled everything. You guys were a big help. Thank you.

I have a vintage door that is very loose- the whole panel is beveled glass. Well, I saved that door for many years hoping I could do something with it- like fix it or something. Well,,, when David (Patron) was here- he said to throw the door away. I haven’t done it yet- but I am going to throw the glass away and probably keep the wood. Don’t you love a compromise?

Stcin, Well done. Good idea with going back to back. Did you contact cement the two together? Replacing the panel worked for me once doing a dog door repair. A month from now no one could ever tell.
