Get rid of woodworm for good (no pesticides)

[@albertplumb7206]

As an Antique Furniture Restorer since 1977, there used to be a company called Themo Lignum (In Notting Hill), London) that carried out this process commercially, even complete buildings. Though I used them (years ago), I have no idea as to what temperature they subjected the furniture to. This is an interesting small scale take on this process.

[@AndysMachines]

That's interesting! I've heard of wood being treated nowadays with microwaves to heat it in various sized kilns, but not if this method was used commercially in the past.

[@cabrerarodrigo82]

Omg thank you for playing music of the sound of foam being cut! Thumbs up just for that!

[@j.b.9581]

This is a nice, simple video. Your narration is straightforward in a pleasing voice (thanks for playing music at the irritating parts). The bits of humor that you add remind me of how much I enjoy British humor!! Thank you from across the pond (and here I am above 5,000 feet).

[@garychaplin9861]

We bought some furniture from overseas which border control found was infected. They disinfected it by placing in a deep freeze for 24 hours. Worked perfectly with no visible affect on the furniture.

[@PanMeeConnoisseur]

Will that process crack hardwood? Am looking to get some old repurpose hardwood Slab to make into table and table tops.

[@AndysMachines]

I didn't notice any additional cracking, the slab I used already had some end-grain cracks which I cut off first (in case they split further). It may depend on the wood species though.

Dude, you are super talented and smart

[@markamy357]

Many thanks, I have wondered if the pests could be drowned or gassed with an inert gas but this looks to be the best way. I have many woodworm.

[@pedropintodasilva1278]

Congratulations: This is the clearest I have ever seen and heard. Others should use your video to learn, before making their videos. How about you making a video about the subject. Most videos have poor diction, are incredibly fast. Again, congratulations. As to the subjetc you gave me excellent ideas. In summary: a 10.

[@f.hababorbitz]

Here in the States, it's Powder Post Beetles that will infest dry wood. I found them in old repurposed bedroom dresser drawers, in what the previous home owner had as an un conditioned metal and work shop area. I've seen them in stacks of firewood as well. They seem to like oak wood. Thanks for the description of kiln drying them to death.

[@alphadog6970]

Very nice tip. And i found out why my new furniture has these holes.

[@Jorvs]

does even does hipping pallet heat treatment prevent it from getting infested or prevents the foreign pest form infection the wood? those things travel from different location it will get expose in some point

[@AndysMachines]

It kills off any bugs that are in the wood, it doesn't prevent future attack but proper storage and use will help.

[@feelfreedesign-hf5gv]

Great video!!! I'm thinking to heat treat my crawl space of our 100 year old house that has woodworm. First close all air holes and put isolation bubble wrap on the floor. Then heat it with portable electric room heaters till we measure 60 degrees. Do you think this would work, or is it an insane idea?

[@AndysMachines]

Thanks! If you can get the temperature uniform then yes it should work, but don't underestimate how much power it might take to do this. It may work with a lower temperature for a longer time, maybe 50°C for a day or two. I'd be worried about overheating areas near the heaters which could be a fire risk. It might be better to split the area up into sections and use fan heaters rather than convection type.

[@feelfreedesign-hf5gv]

@@AndysMachines On a Dutch site I read : "Heat treatment in your home is specialist work. The room sometimes has to be brought to 80 degrees, because the core of the wood must be at least 55 degrees. With thick wood, it may take quite some time before the wood is so warm inside. Unfortunately, it is a costly treatment of woodworm, but the advantage is that you do not have to work with poison or gas. An environmentally friendly method. The cooling will also have to be controlled, so that the wood does not crack or split during the cooling period" So it might be more difficult then I thought.. And they also mention: "The disadvantage is that it is an expensive form of treatment, and you have no protection afterwards. You can do that with impregnation, for example." So now I doubt about the heat treatment... 😅

[@feelfreedesign-hf5gv]

@@AndysMachines Do you perhaps know where to find this machine? (The guy from the video doesn't respond..) kzbin.info/www/bejne/q6mnp6Z3nKisqKc

[@AndysMachines]

I think it's just a humidity controlled extractor fan, maybe like this: www.ebay.co.uk/itm/284488508316

[@feelfreedesign-hf5gv]

@@AndysMachines Thanks for the suggestion! I think it's a bit more complicated machine though as he said it works with bluetooth and measures the air inside and outside on humidity and will based on that blow air in or out of the cellar.. Anyway my search will continue

[@OneHundy]

Fantastic video. Still no sign of woodworm since this was posted?

[@AndysMachines]

A year later and no sign of any having returned. It seems to be pretty effective.

[@gutsngorrrr]

Very interesting, I have a few pieces of wood that have the dreaded worm and was going to treat it with chemicals, but now I might give this a go

[@roseroserose588]

I was surprised to learn that it only needed to get to 60*, I think it being called a "kiln" made me think it would be a lot hotter. Although thinking about it, I'd probably expire after an hour at that temperature too 🤣

[@earthlingi72]

great video ! how ever they can fly in and lay eggs and the cycle can start all over again yes ? Once its FURNITURE it becomes very hard to put in an oven. But saw one person using a heat gun to heat the furniture if they found dust coming from an infestation.

[@sharg0]

A sauna should work perfectly for more / larger pieces as well! just remember that the temperature inside varies a lot with height. (I kinda regret tearing mine down now, still have the heater so I might ponder to make something from it since I have a bunch of trees in my garden I'd like to make planks from)

[@AndysMachines]

Yes, good idea! A dry heat (non-steam) sauna would be good for treating larger wooden objects like furniture, they can reach up to 90°C

[@WorstGamer92]

I have an antique savonarola chair (scissor chair / x-chair) that's full of woodworm holes. Do you think this would work with that?

[@AndysMachines]

Many antiques have worm holes but the worms have long gone and as long as it's kept in a dry environment it should be fine. Unless you're sure there are bugs currently living in it it's probably best to leave it alone.

[@WorstGamer92]

@@AndysMachines 100% sure they're still active. We recently emptied my grandma's house and every single piece of furniture had woodworm holes with sawdust on the floor. Only managed to store two savonarola chairs and a coffee table. I wanna try to save them, but i wonder if the heat treatment could end up cracking or warping the wood.

[@AndysMachines]

If the wood has a higher moisture content then heat may cause it to shrink slightly as it dries out, this shouldn't cause splitting or warping if done evenly. But it may loosen some of the joints.

[@ytrew9717]

Looking for a creative idea to treat roof framing. What about microwaving or (in the future) teraherzt?

[@AndysMachines]

Yes, microwaving is used commercially, terahertz waves could also work but don't penetrate wood as far.

[@Hugh_Mungus]

How did he make the nuts and bolts in wood? looks cool

[@AndysMachines]

They were turned by hand then the threads and non-concentric details added with a CNC router (a home-made 4 axis one). The giant adjustable spanner that goes with them was harder to make.

[@jamesbernsen3516]

This is great, but I have a lot of wood I want to do. I had an oak tree die. It has a lot of good wood, but lots of boreworm infestation, and I want to kill it to recycle the wood for various projects. Any thoughts on a more scalable version of this?

[@AndysMachines]

It's quite common to build dehumidifying kilns out of shipping containers, they normally don't exceed 40°C but with extra insulation you could probably go higher. If you've not already planked the tree up, doing so first would give you more manageable pieces that would fit in something smaller, and you could discard the really bad stuff.

[@recmydream]

Im thinking about sound treatment... I think some frequencies can get rid of some of them even not all of Perhabs it would not be a simple tone, but must be some studies and experiments alread

[@tinaanderson7760]

I live in Portugal and have just bought a house, and the owners were kind enough to leave me some nice wooden furniture. One piece has evidence of worm, though nothing active, and as I have to intall new floor boards I want to make sure this piece cannot contaminate the new boards. In summer the temps regularly get up to 35 degrees celsius. I am wondering, as the piece will fit in the back of my car, if putting it in the car would work. Quite often the car is so hot, you cant touch the steering wheel!!. I could leave it in there for days. What do you think. Its kind of a ready made kiln

[@AndysMachines]

Yes, this is actually quite a common practice in hot countries, for seasoning timber also.

[@ledricelektronika6635]

Although i`m not into woodworking at all this method might be useful in the future. Thanks for sharing:)

[@everywherenowhere6901]

Can I just saturate the wood with methylated spirits?

[@privatekarateka3745]

I'm thinking that emersion in boiling water would work. Although for large projects this is difficult and for non quarter sawn planks, that's gonna be a warping disaster. And what about vinegar? I'm eager to hear people's opinions.

[@peter2327]

3:32 you need a hot wire cutter. nicer edges and no microplastic shavings and durst

[@AndysMachines]

Or loud squeaky noises!

[@geekPlayground]

Can I put the wood inside a kitchen oven at 60 C ? Or maybe using a hot air gun… Microwave them would do it too, I think.

[@AndysMachines]

Large microwaves are actually used commercially. Yes if the item is small enough to fit you could put it in a kitchen oven, but I doubt a hot air gun would heat it evenly enough if used directly on it, you would have to put it in an insulated enclosure and heat slowly.

[@geekPlayground]

@@AndysMachines Thanks a lot for replying. I had never thought of something like this (what you've presented). It's really an excellent idea. I bought an old radio from the 50's and it has wood worm holes. Maybe they are no longer there, but who knows. I thought of doing this using what I have at home and, then, filling the holes with a wood filler used for plasterboard. After that I will sand down the wood, apply wood varnish and some kind of faux leather on top. Please notice that my experience with wood is near to zero, so all of my ideas can be rubbish. Thanks a lot for the effort you put to make this video. It's really an excellent one ! Liked and subscribed !

[@Stierenkloot]

I can't exactly do that to my indoor tree can i

[@fikatzler787]

I have a small wardrobe that has woodworm infestation. As I live in the Algarve, Portugal and the summer temperatures get up to 30 degrees plus - if I leave the wardrobe outdoors in the sun - will this kill off the woodworm?

[@AndysMachines]

It will kill them if you can get it hot enough, (needs to be around 60°C) but the full sun for an extended time might also damage the wardrobe itself.

[@globaleducation2786]

Sir how can we remove these wood eater from furniture please guide us

[@canerandagio104]

Hello, I wanted to ask you if you have abandoned the project of making a full-size T-800. It's been two years since I've posted any more videos on it, I hope you take it back when you're able to, it would be nice to see the finished work... Good luck.

[@AndysMachines]

You've not been paying attention! Yes, I'm still working on the T-800, my last video was about it (3 weeks ago). kzbin.info/aero/PL7T9LOrvm0qLhjKzva1udgoDaV5SBcRWw

You can also take compressed air, and blow out the hole,s. I had great succes this way whit higly infested wood.

[@Miauuv]

👍Can you do that with larger areas of wood as well?

[@douglasharley2440]

[@azinfidel6461]

Was someone hoping you would use the microwave method. 😂

[@camillosteuss]

wasnt expecting this video material from you, not after the t800 parts, but its a good video... Interesting subject and applicable somewhat in toolmaking, regarding handles and grip knobs to keep precision instruments at constant temp while handling... Tho, one could also do the same thing with heated oil for smaller pieces or boards, just get one of those car oil coolant trays that is 1.2mx0.5m(4ftx20in) alu rectangle with 10cm height(app. 4in), get some cheap woodworking oil, like walnut or flax or such, get it on a double burner, smallest flames on each and let her slowly get up to heat... It will reduce viscosity of oil, increase the porosity in wood due to heat, and once cooled, it will have somewhat accelerated polymerization... However you do it, its essentially pasteurization... You could also vacuum treat the wood... But that would be quite a requirement, given that a vac. vessel sufficient to do such a large job would be enormously thick, thereby expensive...

Just ship your wood back to the Permian period, where the high temperatures in central Pangea were estimated to be over 70c.

[@danielmogos8990]

So much effort for treating a wood board? What about buying a new one instead of buying the light bulb, temperature controller, screws, wires, etc? Sorry, but almost worthless what you did.

[@AndysMachines]

It really wasn't much effort, all I had to do was wait! The lightbulb, temperature controller, foam board, and everything else I had already, but even if I didn't they would have cost a fraction of the price of a new hardwood board this size. Plus it's a much more effective treatment than using chemicals. You don't even need the temperature controller, any type of thermometer would do.
