The hinge on my kitchen door have come loose so I tried to use a piece of pine dowel but the screw wouldn't tighten up so should I have used furniture dowels or hardwood dowel.
Should have worked, did you glue it in? Take screw out, glue and wedge in matchsticks so the hole is filled tight, screw back in. If that doesn't work and the door frame is split you may have to either splice a bigger piece of timber into the frame to put the strength back in, or move the hinge positions on the door and frame.
Dowels aren't the best for taking screws. Do the screws just spin or won't go in fully ? If the screw just spins, as Jord says above just glue some slivers into the hole. let the glue dry and try again. It doesn't have to be matches - you can trim some slivers off a piece of wood with a sharp and strong knife
Cocktail sticks similar to dowels not the best wood. I would just get some old timber and slice off some slivers with a trimming (stanley) knife.
Weirdly enough it would probably work, providing you could get enough bite on the screws to hold the hinge long enough for it to set.
Is this a door on a kitchen unit or the actual kitchen door ? If kitchen door - hollow type door ? If hollow, there's not a lot of timber for hinge screws to fix into, 10/15 mm or so Take door off, as above, plenty of glue and some soft wood splints hammered in, wipe off excess glue, allow to dry overnight Don't over wedge as can actualy split edge of door as timber is so thin Other option is to move hinge position and make good Above is assuming it's a hollow kitchen door
Without ripping handandy to bits, please don't put a plug into the screwhole as if the frame/lining is split already and you're struggling for a fixing a plug will only enlarge the hole and eventually make your situation worse.
Just any old bit of softwood you can cut a few slivers from You must have a piece of wood kicking around somewhere, a small piece surely, in the shed, garage ? Your looking at a few slivers around 25/30mm long, you must have something around the house you can canabalise. Real tree wood though, i.e. Not chipboard / mdf Surely you don't have to go out and buy a piece of timber do you just for that tiny amount ? Have you got a loft ? If yes, go cut a sliver from a joist, I'm sure the house won't fall down removing the amount you need Falling that yes matchsticks do work, not so sure on cocktail sticks though
All the wood I had I took it to the tip as I didn't think I would need it. If I use matchsticks or cocktail sticks do I need to drill a pilot hole before I insert the screw.
you get to a point with the remaining material where it does not have the mechanical ability to hold the repair and the hinge. Its then you need to do a splice.
