NO MORE WARPS!!!!! heat treating tips!!!

[@MacomberArtProjects]

I used to watch a handful of videos to help me with my knife making… now I just watch these. Super helpful short and too the point. Thanks! Yeah

[@gentrycustomknives8008]

Wow well I really appreciate that man!! Thanks for watching!

Stress will warp blades. So when you cut and grind knives with grinders and what not, that is creating stress in the steel. The steel also gets stressed when its made at the factory when its pressed into sheets. Some tips would be to lower the rpm and heat when working with the knives pre heat treatment (as well as after). Turn the rpm's down and or cut and grind them under water. You could also water jet. You can also do a de-stressing heat treat cycle. There is also something called vbr, which uses vibrations to remove residual stresses. The other part is to make sure the metal is heated evenly in the oven and quenched it so its evenly quenched. This is major cause the middle will cool slower than the outside. Any stress risers in the design will also cause stress and or issues. Say you have a 1 inch thick blade and mill out a relief for a fuller. This is now a 1 inch to half inch transition that will cause issues. After heat treatment grind under water fed belts to not ruin the heat treat and temper.

Great info!

Normalizing the blade before quenching and temper fixes the knifes stress. You don't really need fancy water jet grinders either, just dunk the blade in a jug of water and cool it down when you start feeling it warming up.

[@tacticalcenter8658]

@@JesusChrist_IsTruth-LoveForALL micro quenching is wrong and not a good practice. You dont want to warm it up on the grinder and quench it in water every time. That just ruins your temper. Normalizing doesnt resolve all the stress all the time.

[@JesusChrist_IsTruth-LoveForALL]

@@tacticalcenter8658 it would ruin the temper even if your not going anywhere near the temperatures you tempered at? 🤔 Thanks for the tips

I've always wondered about that. Good tip!

I'm starting to work with 80crv2 are you considering doing a tutorial on how to normalize the blades i just receive my evenheat kiln and I want to learn how to use it thanks for great content

[@gentrycustomknives8008]

I’d highly recommend checking the new Jersey steel baron website for the heat treat specs!

[@blackdragon4664]

Awesome video! Definitely looking to make myself one of these. Was just wondering if there’s an easy way to tell when to pull it out of the oil? Or will 8-10 seconds be good for most steels and sizes?

[@gentrycustomknives8008]

Yes!

[@blackdragon4664]

@@gentrycustomknives8008 awesome, thanks! Can’t wait to give it a shot.

[@JamesS.254]

Do you heat your oil up at all using a piece of scrap steel, or do you just go in cold on the first dip?

[@gentrycustomknives8008]

Yes I try to keep it around 110-120

[@nerxboy]

How are the aluminium plates holding up with tightening the blades? Any significant profile embossing?

[@gentrycustomknives8008]

So far they are perfect! Probably done around 100 blades in it

[@nerxboy]

@@gentrycustomknives8008 great to hear. Gonna make myself one next week. Cheers

Can we use plates for swords?

[@jimlahey5623]

Hello mister, why do people use compressed air for cooling not the oil? Isnt the oil better and faster?

[@gentrycustomknives8008]

That’s just for the stainless steels

[@Chad_Sandridge75]

My blades are warping during tempering. Any tips?

[@gentrycustomknives8008]

That’s strange. I’ve never had that happen

[@JesusChrist_IsTruth-LoveForALL]

I've had a couple blades warp slightly after temper too!

[@benbroeckx1905]

I'm a beginner. Building my workspace right now almost finished! Thanks for the tip. For the canola oil does it matter if its dark? Like darker canola oil

[@gentrycustomknives8008]

Use fresh!

Do you ever find that after the plate quench it will warp during the temper?

[@gentrycustomknives8008]

No I haven’t experienced that

[@JesusChrist_IsTruth-LoveForALL]

A couple of my knives have! Can't figure out why. They look fine after quench then will end up warping slightly after temper. 🤷😪

[@ThatOneOddGuy]

What's your take on 1075

[@gentrycustomknives8008]

I haven’t used it much really

[@JesusChrist_IsTruth-LoveForALL]

It's good for beginner knife makers! And it's a decent carbon steel. Not super high end but it's decent.

[@ThatOneOddGuy]

@@JesusChrist_IsTruth-LoveForALL yeah I attempted to make pairing knife out of it Mostly failed but the blade could carve aluminum and brass with a 2-20° secondary bevel

[@JesusChrist_IsTruth-LoveForALL]

@@ThatOneOddGuy Nice!! Keep working on it! 💪

[@Advansite]

do you normalize your blades before HT

[@gentrycustomknives8008]

Rarely, depending on what steel I’m doing.

[@Banjoandguns]

If not that’s why he has warping
