toast1 Posted May 14, 2020 Share Posted May 14, 2020 Can I cut a hollow door with a jigsaw? It is recommended to use a circular saw but I don't have one. Can I use this and do a decent job? It is an old UK wood hollow door. Thanks Link to comment Share on other sites More sharing options...
ThailandRyan Posted May 14, 2020 Share Posted May 14, 2020 The blade on the jigsaw and the actual saw speed will not lend itself to cutting the hollow door efficiently. You may end up with it splintering severely from it chattering. 1 Link to comment Share on other sites More sharing options...
Puchaiyank Posted May 14, 2020 Share Posted May 14, 2020 Not a good idea...borrow a circular saw from a neighbor...or offer to rent it for a few baht. 1 Link to comment Share on other sites More sharing options...

No chance, you need a circular/track saw with a guide. if you completed your profile with your location suggestions would be easier, but if you are within driving distance I could lend one of mine.

bankruatsteve Posted May 15, 2020 Share Posted May 15, 2020 A skill saw (what it's called in the states) is best but a bit of elbow grease and a cross-cut saw would probably do the job too. Link to comment Share on other sites More sharing options...
taninthai Posted May 17, 2020 Share Posted May 17, 2020 Op doesn’t state how much he needs to trim of,,,,,Depending on how much you need to cut a plane would be the preferred tool. 1 Link to comment Share on other sites More sharing options...

Having just fitted 4 doors I can assure you that a plane not my preferred tool. My tool of choice is a tracksaw as that gives me a perfectly straight 2.2 metre cut, the thickness to be cut is of no concern. A circular saw with a guide will do the same job. a plane on a hollow core door could be problematic as well.

toast1 Posted May 25, 2020 Author Share Posted May 25, 2020 If I used a fine blade and went slowly after putting down tape on the door - could i get away with it? Any saw will do or does it have to be a long saw? Thanks Link to comment Share on other sites More sharing options...

Perhaps an electric sander may do the job. Link to comment Share on other sites More sharing options...
Metropolitian Posted May 26, 2020 Share Posted May 26, 2020 This thread had me thinking about a scene in Shining. Imagine after the hole is cut and a slice of bread is coming through saying ' Here is Toast ' ???? I have made a cut in the hollow door back at home for a window. A jigsaw was near to destroy the board as they weren't in 'harmony' and I stopped at time. Used a shorter blade and cut the boards at both side of the door and took with a knife the paper-honey-grate filling out. Done. With the PVC doors here I would do the same. Only with massive (wood/non hollow) doors I will use the full length blade jigsaw. Link to comment Share on other sites More sharing options...
toast1 Posted May 26, 2020 Author Share Posted May 26, 2020 (edited) Thanks for the info The door is modern, I think its wood, pressed into a design with 4 squares, not solid wood. What do you mean by 'shorter blade', shorter hand saw? Thanks Edited May 26, 2020 by toast1 Link to comment Share on other sites More sharing options...

A picture says more than thousands words ????♂️ Jigsaw A has a shorter blade than Jigsaw B. I used a broken blade, works great. Short blade exist I have a two of them in my blade-box. Or use a piece of wood to lift the jigsaw from the door. As long the blade doesn't hit at the board on the other side you are good. Link to comment Share on other sites More sharing options...
canopy Posted May 27, 2020 Share Posted May 27, 2020 If the plan is to cut the bottom completely off a hollow door then maybe it's time for a new door instead. A door with no bottom will be terribly weak as it was never designed to have structure taken away. One misplaced step into it can finish it and it will be flimsy, weak and easily deform until that day comes. The hollow opening will also be an attractive home for roaches, ants, mice, etc. Link to comment Share on other sites More sharing options...
dddave Posted May 27, 2020 Share Posted May 27, 2020 You could try clamping two pieces of straight wood parallel to the cut line, one on each side of the cut line. If you measure carefully, you can use one as a guide for the jig saw. That should keep chattering to a minimum. Best to use a new, sharp blade. Most hollow core doors and panels I've encountered in Thailand have a styrofoam filler or baffle inside so if that's the case with your door, it should help in keeping the wood from chattering.

toast1 Posted May 27, 2020 Author Share Posted May 27, 2020 (edited) Thank you so much for he help. I cut the door, went past the wood at the bottom, then my jig saw died. I have to cut off another 1/2" the hollow section. Metropolitan your suggestion is great, as the jig saw is not good for cutting the hollow section, as it is difficult to keep things straight and I don't have clamps, I will try a broken blade.

You should not have got to the hollow section by cutting an inch off the bottom. now you are into the hollow core I would be stripping the skins of the bit you cut off and gluing it back Inside to get some of the integrity of the door back.

toast1 Posted June 2, 2020 Author Share Posted June 2, 2020 I used half a jigsaw blade, and did one side at a time, which worked fine, but I did hit the hollow area as had to go higher than 1" Thank you Link to comment Share on other sites More sharing options...
