WIYB - Machinist Vise Heat Treat

Welcome to the shop. This video is part of a series of videos documenting a machinist vise which is being donated to Kieth Fenner's What's in Your Box effort. We heat treated three parts: a hemispherical washer made by John Saunders, the vise body made by Adam Booth, and the vise jaw made by Brad Jacobs.

Good job on your first video. Was glad to see the process. Pretty cool watching you take my vise out of the box. 😆 thanks for sharing this Tim.

[@harrisevo]

+Abom79 Adam thanks for the encouragement. I can't tell you how much I've learned watching your videos. I look forward to Sunday morning watching the latest with a cup of joe.

[@BasementShopGuy]

Excellent video Tim - thanks so much for being a part of the build!

[@harrisevo]

+BasementShopGuy Thanks Brad. I get sooo much knowledge and entertainment watching what you, Adam, Stan, Kieth, James and the other KZbin contributors do that I just wanted to give back in some small way. IMHO, your efforys organizing the WYIB builds really coalesced the community. I better appreciate the amount of time it takes to film and edit these videos, which is huge, so thanks again.

Given the flames when quenching, I have two suggestions. Get or make a basket for the piece to fall into should you drop it or use a metal bucket. That piece contacting the sides of that plastic tub is a recipe for disaster especially when flames are present. Have a cover handy as well as an extinguisher in case the flames do no self-extinguish (Spontaneous decombustion)

[@RichardHeadGaming]

Nice of you to take part in WIYB, and liked watching the process of the treatment.

[@harrisevo]

+Richard Schmidtendorff I've watched and learned a lot from Adam, Kieth and the other KZbin contributors. I wanted to give back in some small way

[@bigbob1699]

Please tell us that the maker of the vise knew exactly what steel he used . You need MORE pre heated oil and a hood . A heat treating foil wrap would be a great help .

[@melgross]

This whole thing made me shudder.

[@tomthumb3085]

Great vid. Always good to see a new maker on the scene. There can never be too many good makers.

[@shadowdog500]

I was watching the vise go together, and somehow missed this video until today. Looks like a neat process. I hope to see more knife making videos from you. Thanks, Chris

[@harrisevo]

+shadowdog500 Thanks

[@jerrylong381]

Hey Matt &Tim, That's one nice oven! The air hardening steels are nice. I've precision ground a lot of D2, S7, A2 and 440C. D2 is a bear, but I would love have a knife made from it. Thanks for the video guys.

[@axodal]

I really enjoyed this video. Very interesting and educational! Great videography as well! Just want to encourage you to make them longer and more detailed. We technical guys love details. LOL! Great work!

[@harrisevo]

+axodal Thanks much

[@mrbluenun]

Really nice job, which is complicated by the 5 or 6 people or more making the various parts to this vice, OK if like you this is the final grind but there’s a lot to think about, well done to you and all. I know in one of the last WIYB’s a person from the UK where I live was the lucky recipient of a box, or to be more correct many individual ones that made up the whole wonderful gift from knowledgeable Engineers and Part time and Professional Machinists. I hope they realise just how much work went into their many separate pieces! I have said it before, - I wonder if Keith realised what a many headed snake these WIYB would become, though it spreads the knowledgeable camaraderie of the many people kind enough to make the many parts of maybe even more finished machinists tools with some becoming absolutely indispensable and are for continued use?! Thanks for the completed item and for the upload of your work. Take care mrbluenun

[@harrisevo]

+mrbluenun I couldn't agree more.

[@Za7a7aZ]

A link to the next would have been great.,..

[@jessefoulk]

I missed this part in the process for the WIYB vice. Came across it.

[@WAVETUBE84]

Great addendum to the machinist vice collaboration. I bet your electric meter was spinning on this one! You could calculate the "$ kilowatts pretty easily...

[@melgross]

I was really nervous about such a large part being put into such a small plastic tub of oil. I use a 36 quart stainless stockpot, with a cover that can be dropped on the top with a push of my foot in an emergency. I have 7 gallons of actual quenching oil inside. It’s not that expensive, particularly for a business. Most other oils are contaminated by ingredients that shouldn’t be in hot contact with the steel, and have a flashpoint that’s too low. I don’t see that large, thick part being properly quenched in such a small volume of oil. I noticed that you mostly held the part without moving it much. This might be fine for a knife, but for precision tooling, it’s not. I’m sure Stan will grind it nicely, and that the surface will be about where it should be. But I wouldn’t trust the long term stability of it.

[@deej19142]

Wow that's a glowing fire bomb! And I thought it was hot opening the oven to check the turkey. YOUSER!

[@harrisevo]

Yep. This was only 1550 F. Some steels are up to 1920 F. Its like getting your shirt ironed on your body LOL. Thanks for the comment

[@luizguilhermecosta7221]

Hello. what type of steel was this vise produced? thanks. Luiz Guilherme

[@bcbloc02]

I have done a lot of double and triple tempers but this is the 1st time I have ever seen a double quench done. What was the reason?

[@harrisevo]

+bcbloc02 Hey Brian. Yeah you're right, we never do double heat treats. That was recommended by Stan, so that's what we did. We routinely do two 2 hour tempers on all the knife blades. I'm no metallurgist, but according to one at work you can do that to differently harden parts, but not sure why that was needed here. As you know different materials have different specs. Without knowing the material, we just followed Stan's recommendations based on his experiments with a piece over the summer.

[@AlexeiPolkhanov]

+harrisevo So you guys did not know exactly what type of steel these parts were made from? I remember watching a video where Adam was cutting a piece of another bigger piece of stock and he mentioned the source of it. Perhaps there was a way to trace down a data sheet for that steel.

[@harrisevo]

+Alexei Polkhanov Alexei all the steal for the vise came from Adam's shop. Adam said the piece had been around his family shop (certainly during his father's time and maybe his grandfathers time) and didn't know its origin. So no data sheet was available. Thanks for commenting

[@pierresgarage2687]

+bcbloc02 I agree with you Brian about the second hardening.... ???? To have more clue about the type of steel, there would have been possible to send multiple small samples of the steel and do some test at different temperatures, then, determine the needed temp for the needed hardness, there are soo many different of steel, lots of those steel have tempering temp way above the 400 F, more like 600 to 1100 to get 55 to 35 RC... Don't look like they test the hardness of their production... ;)

[@bcbloc02]

pierre beaudry Maybe Tom could have hit it with one of his hammers after they ground it to see how hard it was. LOL

[@jerrylong381]

Would like to see some knife making videos from you guys. Just sayin

[@DieselRamcharger]

Does that oven have a controlled atmosphere? I don't see how you stopped it from decarbing soaking that long….

[@harrisevo]

+Diesel Ramcharger Diesel - no controlled atmosphere for oil quenched steels. the longer soak time was to ensure that the entire part reached the critical temperature. We do heat treat air cooled metals that are foil wrapped to control oxygen during the process. Paper is added to the foil pack, so at high temps the paper burns consuming the oxygen.

[@scottniedentohl6926]

Isn't ATF extremely flammable?

[@jmanatee]

Cool Video,... You should do more,...

[@harrisevo]

+jmanatee thanks for the encouragement

[@TheMetalButcher]

Can you not coat it in something to help prevent the oxide?

[@MattOGormanSmith]

+justfakeit888 You've been watching Clickspring too? :) I doubt the vice body would fit in Clickspring's blueing tray, and it's getting ground all over after hardening.

[@TheMetalButcher]

Yes, yes I have been watching clickspring. :o I realize it's going to be ground, but it seems like it would still be nicer to prevent the oxide in the first place.

[@darronjknight]

+justfakeit888 it may be possible to use a flux type of compound, but other may not be the kind of stuff that you want to get onto the walls of your heat treat oven, so not worth the effort

[@johnptc]

+justfakeit888 wrap the part in a piece of paper and the wrap in stainless steel heat treat foil. As the part heats the paper will consume any available oxygen when done remove foil :)

[@TheMetalButcher]

I'll have to try that, sounds interesting.

[@DougHanchard]

Home heat treat. woof, for that mount of time.... hate to see your electricity bill !!! *faint* Nice job!

[@harrisevo]

+Doug Hanchard It's 220v so its not that bad. Also it's very well insulated and efficient at holding a temp. 1500 degrees isn't too bad. Some steels are heat treated at over 1900 degrees

[@DougHanchard]

+harrisevo How many watts do the heating elements put out? 220V keeps the wires cool, but damn, the kWh must have your meter spinning like crazy.

[@shantahsieh2877]

Try some new solutions from Avasva solutions.

[@Patroand]

you may try this oil www.mcmaster.com/#3202k1/=10f800h for your work.

[@harrisevo]

+Robert Patoine Robert good suggestion. Most of the oil quenching we do is for 1095 and since the parts are small, a large ammo can works pretty well ; ) Because the vice base was much larger than what we normally do, we had to improvise with a larger container (plastic 5 gal bucket).

[@АлександрП-х7р]

Я сомневаюсь в том, что в 10 литрах масла можно заказать корпус тисков. Этого количества масла хватить лишь на 10 граммовую деталь... Плохая работа ребята, надо знать теорию и практику!
