Well, yes i thought i understood, but after seeing your other videos i thought you would clear up any misunderstandings i had. Am i correct in understanding the two processes, vacuum and pressure treatment are used sequencially or can be used as seperate ways of naturising wood? Depending if the wood has been 'seasoned' or dried. Treatment 1, vacuum extracts moisture and air, whereas treatment 2, pressure, forces the resin into the wood whether heat treated or not and still having a variable amount of moisture within it. I can obviously see that using both treatments sequntially will give you essentially a 99% block of hard resin to work with. There are many videos out there, mainly American and using 'Cactus Juice' but are either one or the other, not both. Many thanks though, its good to see a British method. Just a problem finding Cactus Juice over here. Have you tried Ronseals wetrot resin? i wondered if this was a viable option?

Hi John, Wetrot resin if it's what I think it is will not work well as it boils under vacuum and will gum up the pump, Also it melts at low temps and will make a real mess and shorten the life of your grinding belts when shaping the wood. whereas Cactus juice does not. Cactus juice is really Methyl acrylate resin so if you google search that you will find alternatives here in the UK. The process I now use to stabilise most woods is as follows. 1 Dry wood slowly at first with the end grain sealed. 2 when it's as dry as you can get it by normal means (storage in a dry warm place for weeks or months) then transfer to an oven heated to 110C and drive off any remaining moisture. (This may take a whole 24 hours and you are looking at zero moisture remaining in the wood) Don't forget to remove the sealing material from the end grain at this point before you cook the wood. 3 once the wood is cooled then submerge in resin and apply the vacuum. You need a pump capable of as close to 10PA as possible. Leave the pump running for around 6 hours. Turn the pump off and the next day remove the wood, rotate it through 180 degrees and run the vacuum again for another 6 hours. 4 After the second vacuum treatment, turn the pump off, allow atmospheric pressure in and leave the wood for as long as possible. If you don't need it for sometime just leave it soaking in the resin til the time you do need it. I would advice a minimum of a week for woods such as walnut. Birch on the other hand takes the resin really quickly. 5 after a good long soak you can transfer to the pressure pot operating at 4 to 6 bar and try and squeeze a few more drops of resin in, but I am uncertain how much more resin I am getting into the wood using the pressure pot as the level does not appear to drop by much. 6 drain and wrap in foil and bake at 100C for a minimum of 5 hours. This is what I do nowadays and the results are excellent.

Jackloreknives Many thanks for taking the time to explain further. Much appreciated. Myself and my son made a couple of knifes two weeks ago today for a local Annual Bank Holiday show. Mine from a bucket forged rebar and wood from our apple tree and my son ground down a piece of bought Damascus steel with a piece of spare wood from a wood turner, lemonwood we think. Once finished we oiled both handles mainly because of the timeframe. We both came second in the respective classes. As I have a workshop with compressor etc I would like to make any future handles potentially more permanent so your information will prove invaluable. Also an anterior motive as I'm setting up my workshop to create guitars, acoustic and electric and think this process will be useful for improving sustain in necks and headstocks and bridges. Cheers John.

LOL Cactus juice is methacrylate resin, there are other manufacturers, one is called "Stickfast resin". It's all the same stuff, I've even mixed brands and it works all the same. The only thing I would advise anyone now after several years of stabilising wood is don't waste your money on an expensive vacuum pump, you can get cheap pumps that will pull the same vacuum.

So, is there a mild heat stage to the process to set the resin? I ask, because I've heard the Cactus Juice called thermo-setting resin. And if there is a heat stage, when does that occur? Right after pulling the blocks from the pressure pot? After the block is cut for scales?

To clear up some of your misunderstandings, heat does not rise. Heat transfers to the coolest place. The best example I have of this is mountain tops. Why is there snow up top and valleys are the hottest places?. .. look it up I am a LEED qualified green energy manager. Just thought I would let you know

If heat don't rise why do we have thermal air columns that rise? Yes heat does rise. But every few hundred meters in height you go you will find the air generally gets cooler. Eventually heat is lost from the planet through radiation to outer space. Here's an experiment for you to do. Grab a long piece of steel and heat it in the middle. Then tell me which will be hotter, the top or the bottom? The top will become much hotter than the lower section thus proving that heat will rise more readily than go down.

Very diplomatic of you to accept fault for other's lack of understanding! This really hit home to me the justification of cost of handmade knives!

What's the purpose to stabilise the wood handle
@Quagmire88
7 жыл бұрын
Its injecting resin into the wood. It is used to harden and "Stabilize" the wood. This keeps the wood from breathing. It stops the expansion and contraction of the wood fibers due to temperature and water contact, as well as keeping it from drying anymore and cracking after its been attached to the knife tang.
@pureheroin9902
7 жыл бұрын
If you ever see a really old knife with wooden handle material still attached, have a close look. You'll see big gaps where there used to be close fitting edges, many times they will be loose and only held in by the pins. A lot of the time half the wood will have split off because the wood expands and contracts over it's life span. Stabilising the wood gives all the aesthetic benefits of wood, while adding modern resin qualities.... Water resistant Wear resistant Won't swell or contract High temp resistant I use resin laminates on my scales as I know the material is strong and long lasting. I'd much rather use wood, and I will swap to wood when I get all the kit I need to stabilise my scales.

Your explanation is supremely clear and straightforward. I do not think that the people that misunderstand are short a few marbles either. What I am seeing more and more of is that people are doing multiple things at once and then they miss a step or bit of info and get confused. I am one of those who believes that multi-tasking is bunk. I think that the brain can switch rapidly between tasks but still can only really focus on one thing at a time, the speed at which people can change their focus back and forth has given rise to the false concept of multi-tasking. Therefore when people try to do many things at once they are really only doing one thing at a time but are switching between things and therefore miss information leading to misinformation.
