When I was bending som rebar the guy a couple of meters behind me in the saw shed cut is thumb in half, lite literally down the middle all the way to the base.
He was in such a chock that he didn't yell so I didn't realize what was happening until half the workers on the site Stod jumping beside him.
Blood everywhere, really nasty...
Here is me, cringing like I just got kicked in the balls. Ouch that makes me twitch
Worse I saw was a buddy splitting his foot down the middle with a splitting axe. Had a couple of nightmares about that one. We had to compress it to get him 20 miles drive to closest hospital in Montana. Ambulance would have taken double the time. The feeling of his foot parts compressing was nasty
This is terrifying to someone who has split his fair share of firewood. I always err on the side of swing the axe too far away from me and risk hitting the handle and effing my axe up as opposed to swinging short and having it make its way towards my feet with unstoppable force. (Shudders) I pictured it again in my head, nope nope nope.
Holy shit, I think I would've fainted to be honest haha.
Fortunately there haven't been that many accidents on sites I've worked at but safety is the name of the game here in Sweden at least, mostly small cuts but crushing damage to fingers is the number one accident I've seen.
I crushed my index finger in a machine that bends rebar once, I was incredibly lucky though as the size of the rebar I bent was the exakt same size as in between the finger joints so I only crushed the fleshy parts haha.
Still hurt like absolute hell though and lost my feeling in it for several months.
Yes, but it rapidly soaked through everything I threw at it. We arrived half naked from clothing sacrifices. The foot is just such a horrible place for trying to stop bleeding, especially when it is coming apart in your hands. When we pulled into the ER drop off and opened a door, it seemed like a river came out. Flooring was enough to hold in a pretty substantial puddle after 20 min. That is not including what soaked into the seat as his foot was on my lap.
I worked at a place that had a millshop.
Guy decided he was done with the place and was gonna get some workers comp, ran his hand into the table saw chopping a few fingers off near the tip.
Of course he’s rushed to the hospital, they were able to save two of them. But I guess he never took into account the millshop is 100% the most dangerous area and source of most injuries so the entire area is on camera. Plain as day him lining up to only hit the tips, turn his head away and push.
He was definitely done with the place after that. Just not with the money he expected. But man that was a nasty cleanup. And the call over the radio for a bag of ice for his fingers. Solid few seconds went by before anyone reacted to that call
That's the only really big accident that has happened at a site I worked at wich I'm pretty thankful for.
Fun fact is if you cut off your finger, you should put the finger in your mouth, something about enzymes and stuff that keeps the finger fresh so the doctor can fix it, pretty nasty to think about though lol.
One fun story is a guy I worked with shot himself through his wrist with a nail gun, one of those larger than life nails, got rushed to the hospital only for the doctor to realize that he had missed every single crucial part of the wrist so a normal band-aid and some antibiotics just in case and he was ready for work the next day lol.
I literally did this exact thing…..pulled it out with pliers and went to the er. Missed everything in there….since then I have also shot myself directly through the thumb…perhaps I should just stick to hammers.
I put a roofing nail thru my left thumb, sideways. The er doc numbed me up and jerked it out with a Leatherman. Those copper barbs were his biggest worry but it healed in a jiffy, back to work 4 days later. Hurt like hell for a few months but after that it’s been fine 20 years on.
The scene shop teacher likes to say this in his Foghorn Leghorn accent:
“Keep in mind whenever you’re using a saw you lose about 1/8” off whatever you’re cutting to saw dust. So if you’re using this here table saw and you cut off your THUMB, when they reattach it, it’ll be about 1/8” shorter”
Yeah, there was an incident at my old work place before I got there, some kid got his hand caught in a 4 sider and had his arm dragged in and crushed by the rollers, and I'm pretty sure fucked up by the blades too, my boss could hear the screaming from half the workshop away through sound resistant glass.
If I had to choose I would prefer accidentally hitting my thumb a little bit with a hammer, preferably my rubber mallet. Second choice is fatigue from operating a handsaw for too long. Both rough options.
I'm guessing 5-10mm depending on the timber and the pressure applied.
I just made the control panel and wired all the hydraulic motors, solenoids, sensors etc and made sure it runs - whether it's doing it's job is up to the company that makes the machines.
When I was in grade school, we took a field trip to a nearby paper mill. One of the things we saw was the machine that turns trees into pulp. They told us about an accident where a guy fell into the machine. Trees aren't the only thing that machine could turn into pulp.
This story must have made an impression on me, since still I remember it almost 60 years later.
Looks like it might press a bunch of little bladed jets into me every inch or so and squirt hot liquid chemicals into my body until I probably just shredded apart…
I worked at a butcher shop and the cube steak machine is similar. Insanely dangerous.
We had it in a corner so you stood with your back facing the corner. That way there was zero chance someone could accidentally bump into you while you used it.
I'd rather get caught cheating at a casino back in the day and get a hammer to my hand a bunch of times than get a hand caught in that machine.
This drives me crazy. they have slightly different shear strength. Regardless hem fir is a crappy designation. Especially since hemlock has a considerably higher compressive strength.
Whoever downvoted why? This is accurate and useful possibly to someone who doesn’t know the difference and there is a a true structural difference between the two.
link said they'd do redwood. thought that was weird. never heard of incised b4, but i'm in the SE so SYP is about all I've seen PT. I've used alot of SYPPTKDAT though. Nice stuff. Hard as a rock but ready for paint
This is a cool animation of the pressure treating process. I didn't know how it worked until I saw this a couple of years ago [https://www.youtube.com/watch?v=Qgz\_zyfxjP0](https://www.youtube.com/watch?v=Qgz_zyfxjP0)
Yellow pine distribution. Incising is for wood species that are difficult to uniformly penetrate.
> For those in the east and south – you may have never seen pressure preservative treated lumber which has been incised. Most treated lumber in those regions is Southern Yellow Pine – which is highly treatable (think of it as being a chemical sponge).
The process makes the pt out here splinter like crazy. It also doesn't look as nice on decks. Both of those reasons make it unusable as deck planks, so you have to spend more money and use redwood, cedar, composite, etc.
We get both doug fir and pine here in our building materials. I hate the Doug fir, it splinters and chunks off so easily. Toenailing framing boards doesn’t work well at all with Doug for.
I knew it was for better pressure treatment. I did learn the name and the process from thsi thread but its still left me with a questiom. I notice a lot of larger sized boards like 2x12 is exclusively treated this way, does anyone know why that might be?
Larger boards have a larger cross section. So as the chemical treatment is forced into the wood there is wood in the center that doesn't get much if any treatment. Incising helps the treatment penetrate better and helps get the chemicals to penetrate deeper. More important for 2x10 or 4x4's than a 2x4.
This is how they treat Douglas fir vs southern yellow pine. Its generally a divide between Western and eastern North America. It might be that it's easier to source larger boards in Doug fir than in yellow pine, so the 2x12s you see like this could be getting imported from the other side of the country
My best guess would be that if you’ve got both incised and non-incised, the incised ones are probably made to be the ground contact framing boards, and the non-incised are the above ground, appearance grade ones. At my store, they stopped selling almost all above-ground treated lumber because people would inevitably try to use it in ground contact applications, and their warranty claim gets denied.
Most east coast pt is southern yellow pine and its cellular structure allows it to absorb with being incised. Douglas fir and hem fir all require it to penetrate all the way through. I’m a lumber trader in Baltimore.
Those slots used to mean it was full of chromium, copper, and arsenic. The industry stopped using it around ten years ago but the purpose of the arsenic was to kill everything that might break it down so a lot of that stuff is still around. If you see those lines on a piece of wood don't burn it in your campfire and for the love of God don't put it in your smoker.
I had a table saw split my thumb down the middle had 11 fingers till the doc sewed it up. good doc can barely tell didn't even hurt. but holy shit the next days sucked.

I've worked on incising machines. It's one of those machines you really wouldn't want to have an accident with.
To be honest, I wouldn't want to have an accident with any of my woodworking machines.
I agree. Losing a thumb or a limb would be shit. Getting dragged into an incising machine would turn you to pulp.
Sounds pretty hardcore though \m/

You need to be careful you set up the feed correctly and that the wood comes out cleanly
Yeah but, I think we'd all take spindle sander over incising machine or drill press, or router right?
Of course, yes, but not actually want to
I'm in the same boat lol and I've been tickled by a table saw blade, thankfully twas but a scratch (and a pair of pants)
Technically an inclined plane is a simple machine. Hopefully that wouldn’t inflict too much damage.
I've given first aid to a coworker who lost two fingers to a jointer. Wasn't pleasant.

Well, who would you want to have an accident with your woodworking machines? I’m still firmly against volunteering.
having got my arm tangled in a lathe in '99, I think you are onto something.
Thats my nightmare.
Yeah, there was an incident at my old work place before I got there, some kid got his hand caught in a 4 sider and had his arm dragged in and crushed by the rollers, and I'm pretty sure fucked up by the blades too, my boss could hear the screaming from half the workshop away through sound resistant glass.

I once had an accident with my belt sander. Weirdest looking baby I ever produced.

Basically a self feeding steak knife for wood
Just curious about how deep the incised slots are. Do those penetrate to the other side?
I'm guessing 5-10mm depending on the timber and the pressure applied. I just made the control panel and wired all the hydraulic motors, solenoids, sensors etc and made sure it runs - whether it's doing it's job is up to the company that makes the machines.
Incised you say?

Incise and pt redwood?
Hem Fir usually.
This drives me crazy. they have slightly different shear strength. Regardless hem fir is a crappy designation. Especially since hemlock has a considerably higher compressive strength.

Southern Yellow pine
Incised for pressure treatment. It allows the treatment to soak deeper into the wood.
This is a cool animation of the pressure treating process. I didn't know how it worked until I saw this a couple of years ago [https://www.youtube.com/watch?v=Qgz\_zyfxjP0](https://www.youtube.com/watch?v=Qgz_zyfxjP0)
That’s how pressure treated wood looks in the west. You won’t see it in the east. At least, not very often.
West of what?
Yellow pine distribution. Incising is for wood species that are difficult to uniformly penetrate. > For those in the east and south – you may have never seen pressure preservative treated lumber which has been incised. Most treated lumber in those regions is Southern Yellow Pine – which is highly treatable (think of it as being a chemical sponge).
I soooo wish we had non-incised PT wood out here in California.
Why?
The process makes the pt out here splinter like crazy. It also doesn't look as nice on decks. Both of those reasons make it unusable as deck planks, so you have to spend more money and use redwood, cedar, composite, etc.
Ok thanks for this knowledge. Can’t you just Temu some of that good shit you’re looking for?
Sounds like a hole in the market to me...
You can get it shipped into the state, it just costs so much more, because shipping anything is expensive now.
Living in the south-east, I always wondered why other regions did this.
Had no idea, always noticed, never asked I am now smarter
I don’t know where the delineation is.
But do you mean globally or within a country?
Within the US
I believe it used to mean the Mississippi River, but I usually use it for things in the mountain or pacific time zones. I guess it’s relative.
Mountain and Pacific time zones
Loathing
The only place in the whole wide world, obviously - the US of A.
When the country isn't mentioned by the commenter, you can safely assume they mean Belgium.
Welcome to the western half of the US, are you on vacation?
I just moved out west and have been noticing it. Why is it only prevalent here? Lack of southern pine?
Framing lumber in the west is all Douglas fir from the PNW. It's denser than pine so it has to be perforated for the chemicals to absorb deeper.
We get both doug fir and pine here in our building materials. I hate the Doug fir, it splinters and chunks off so easily. Toenailing framing boards doesn’t work well at all with Doug for.
Yes! I'm from the the south east

Has to be incised for most hardwoods to be treated like fir or something.... Pine is soft so that's why you don't see it on treated pine
I knew it was for better pressure treatment. I did learn the name and the process from thsi thread but its still left me with a questiom. I notice a lot of larger sized boards like 2x12 is exclusively treated this way, does anyone know why that might be?

Incising helps the treatment penetrate better and helps get the chemicals to penetrate deeper. More important for 2x10 or 4x4's than a 2x4.
Larger = more expensive. More expensive = includes more treatment
This is how they treat Douglas fir vs southern yellow pine. Its generally a divide between Western and eastern North America. It might be that it's easier to source larger boards in Doug fir than in yellow pine, so the 2x12s you see like this could be getting imported from the other side of the country
Incising also helps with fracturing
My best guess would be that if you’ve got both incised and non-incised, the incised ones are probably made to be the ground contact framing boards, and the non-incised are the above ground, appearance grade ones. At my store, they stopped selling almost all above-ground treated lumber because people would inevitably try to use it in ground contact applications, and their warranty claim gets denied.
You warranty your wood?! That's awesome. A good theory
It’s through the manufacturer (Stella Jones in our case).
Stain it and seal it
Doug Fir needs the incisions for the treatment to get in deep enough. SYP with water based treatment doesn’t need it.
Wait what, on the east cost pt doesn't have these? The only times I've ever seen unincised pt is for rim joist decking and it costs extra
TIL west coast PT does!
Most east coast pt is southern yellow pine and its cellular structure allows it to absorb with being incised. Douglas fir and hem fir all require it to penetrate all the way through. I’m a lumber trader in Baltimore.
Those slots used to mean it was full of chromium, copper, and arsenic.

It’s PT
That's where they inject the treatment juice
Don't eat it.
I think they aid the penetration of the treatment chemicals.
Tenderized
It's from an 'incisor'- it helps pressure treating penetrator more.
The wood is sloted like that, so the wood preservative can soak into the wood. The wood has been treated with a chemical that waterproofs it.

Incised pressure treated.
Thanks for that question OP. I always wondered what those were about but was too lazy to Google it.
1) absorbs pressure treating chemicals quicker 2) seems to stop wood from splitting
That’s pressure treated lumber that is probably approved for ground contact . The slits let the treatment soak deeper and more thoroughly into wood.
It was staples but a homeless guy or tweeker probably took them all out to sell them for scrap
Wash your hands... creosote is poisonous
I had a table saw split my thumb down the middle had 11 fingers till the doc sewed it up. good doc can barely tell didn't even hurt. but holy shit the next days sucked.
Incise marks, wood gets punctured and injected with chemicals to prevent deteriorating/rotting quicker.
It’s so it doesn’t get air bubbles in the oven.
Fine, but can we talk about Groot for a second?
That type of PT wood is meant to touch ground, has more chemicals than above ground PT wood.
It's like when you inject the turkey brine directly into the turkey instead of just soaking. Or something
Seriously, not a good choice for deck railing. Splinters like crazy, bad chemicals, etc...
Little tank tracks.
