Hey guys, I'm new to knife making. I have been searching the forum to find the answer to the question that I have but have had no luck.

I was wondering if there was a way to determine what kind of metal is what. For instance I went to the local scrap yard and aquired some leafsprings. Are they generally made out of a certain type of metal? I have noticed that they are tapered so my type of knife making (grinding) makes it hard to get an even edge. Or it may just seem that way to me since I'm a novice.

I have also gone to the local hardware store (Loes) andy have seen that they have hot rolled and cold rolled metal. I have done the research on what hot rolled and cold rolled is but have not been able to find if it is made frome a general type of metal. I asked the associates that worked there and none of them had any clue what I was talking about.

Any information or links to another thread regarding my question would be extreamly helpfull and appreciated! :)
 
You can't buy good knife STEEL at Loes [Lowes] or Home Depot.

The only way to know for sure what used steel is is to have it tested, which is expensive[$50 or more]. Leafspring may have micro cracks or stress fractures that will affect the quality of a finished blade. Unless you have a lot of experience working with steel, it's better to buy new 'known steel'.

Check out www.njsteelbaron.com. Aldo is well known in these parts & will treat you right!!

And welcome to Bladeforums. Read a lot, try a few things, ask questions and have fun!!
 
Randy gave you some sound advice. Most folks here don't want to see you get off to a bad start.

Again, Read a lot, try a few things, and ask questions......... Above all...... Have fun.

Knife Design:

Think thin.
Forget swords, Saw-tooth spines, guthooks, crazy grinds and folders for your first knife.

Start with a drawing.
Show it to us, we love to see and comment on photos.
Then make a cardboard cutout template & draw in handles, pins and such
Then use wood, paint sticks are free & close to the right size.
If it “feels right”. If it feels right it usually “looks right“

It’s being reprinted now; you can get it for $20 ish

The $50 knife Shop
It confused me for a long time.
Forging is NOT necessary; you can just file and grind to create a knife (stock removal)

Forget the Goop Quench.
Use commercial quench oil & match oil speed to the steel type; even grocery store canola oil works much better for some steels.

Junkyard steel requires skill and experience to identify and heat treat it properly.
Forget Lawnmower blades and start with a new known steel type.
Good heat treating needs accurate temperature control and full quench.
You can buy proper steel like 1084FG from Aldo very cheaply.

I like cable damascus, but that advanced project has no place in a beginner’s book.

The grinders are the best thing about this book, but there is a huge amount of info for 2x72” belt grinders on the web, including free plans.

Steel
The “welding steel” at Home Depot / Lowes… is useless for knives.
Forget about lawnmower blades ,files and other unknown junkyard steels.
For all the work involved, it is very cheap to buy and use a known good steel.

If you send out for heat treating, you can use
Oil quenched O1, 1095, 1084
Or air quenched A2, CM154, ATS34, CPM154, 440C, plus many others.

For heat treating yourself with minimal equipment, find some Eutectoid steel.
1084FG sold by Aldo Bruno is formulated for Knifemaking, Cheapest & made for DIY heat-treat.
http://njsteelbaron.com/
Phone # 862-203-8160

1095 is a good carbon steel, but a bad choice for a beginner with limited equipment.
1095 is "Hypereutectioid" and needs very precise temperature control and proper fast quench oil Like Parks 50 or Houghton K
Kevin Cashen - 1095 - hypereutectoid steel http://www.bladeforums.com/forums/showthread.php/673173-Working-the-three-steel-types

If you are sending one or 2 knives out for heat treatment, use 154-CM or CPM-154 or CPM-s35vn and ship it out to TKS -Texas Knifemaker Supply
It's the cheapest way to do 1 or 2 because of HT minimum charges.

Quenchants for Oil hardening steel
Forget the Goop Quench. Motor oil, it's toxic and doesn't work that well.

Use commercial quench oil & match oil speed to the steel type;

Grocery store canola oil works well enough for your first knife-if you use the right steel.

Brine and water are almost free, and technically correct for W1 and "water hardening" steels but a fast oil like Parks 50 and Houghton Houghto Quench K are less likely to give you broken blades.
If you use water or brine, expect to hear a "tink" and have a cracked or broken blade

Glue – Epoxy
Use a new package of slow setting, high strength epoxy to attach blades to handles and well as seal out moisture.
Surface Prep is vital, drill tang holes/ grind a hollow, roughen the surfaces with abrasive, blasting is best.
Ensure the surface is clean & no oil including fingerprints. Soap, Acetone & Alcohol, Blasting.
Clamp with moderate pressure= avoid a “glue starved joint” when all the adhesive is squeezed out.
These are well proven.

Grinder / Tools

In my opinion, variable speed and a small wheel attachment are essential on a good grinder.
You can almost always improve tracking with more belt tension. It needs to be way tighter than you first think.

Hand Tools
You can do it all by hand with files and abrasive cloth like the Green Pete video.
Files can be made from unhardenable steel, or steel similar to 1095 that needs a difficult HT
Just use 1084 instead of a file.

VFD Variable Speed made simple

Simplest, and cheapest are hardly ever the same, but:
Step pulleys are not as cheap as you may think
Maska cast steel pulleys are good and well balanced $75 EACH here plus shaft, bearings, belt

It all adds up to about 1/2 the price of a KBAC-27D

I like direct drive, no belts and a VFD for about $200 over the price of the step pulleys with much finer control.

Yes you can get cheaper NEMA 1 VFD’s and build your own enclosure
Or you may find them cheaper at other retailers, but watch shipping.

VFD-
KBAC-27D

Motor
3 phase 220v 1.5 HP motor, TEFC, frame 56 or 56C,
RPM is up to you many are happy with a 1700 RPM running at double speed.
Make sure it has a footed base for the KMG and NWG, or a C flange face mount for Bader and GIB styles.
I get them on ebay, even with paying $80 for shipping to Canada I save $$$ on a used motor.


The 1.5 HP combination is the most common setup, as reported by Rob Frink in some thread somewhere
It allows you to plug into any 110vac, 15 amp outlet.
A 2 HP motor requires a 220vac input.

There are cheaper VFD units like the TECO, but the only VFD I have found that will run a 1.5 HP motor on a 110v 15 amp input is the KBAC27D

It is NEMA4, sealed from metal dust that can burnout the unit.
It has good community and company support, manuals, hook-up diagrams, photos and settings on Rob Frink’s website.

I like the fact that I can buy it from a local distributor in Canada.

Travis W reports running a 2 HP on a 110v circuit, but I haven’t tried it.

Hookup is dead simple

Use a VOC & P100 combo cartridge for protection against acetone and solvents.
There are also prefilters that snap over the main filter for longer life.
There are 3 sizes, buy one in person at a safety supplier and get it fitted.

Welcome to Bladeforums.

Most of the folks who have make a lot of knives will tell you to leave the scrap steel in the junkyard, and order some 1084 from Aldo. A known steel is what you want. Just because someone "Says" leaf springs/files/hay tines are XYZ steel doesn't make them that. If a steel supplier says his steel is 1084/1095, W2....then that is almost surely what it is.
 
Thank Robert, Randy, and 12345678910 for the information that you have provided me with. I have been researching everything and it has always brought me to BF with great information. So I had to join. I will research, ask, and test everything I need and learn.

I have already made one knife. Its a little neck knife that I made from a small piece of metal a knife maker gave me a while back. All hand filed. Started another out of le leafspring I mentioned, but that is now a template for me. Its time to take a look at what Aldo has and get started on proper metal.

Thanks again

Edit- that's what I'm going to do from now on bladsmt, leave the scrap in the scrap yard Lol.
