Read all the way through this post.

I am preselling 10 sets of straight-sided mandrels, Rockwell 60+ hardness, which is equal to or greater than Carbide Steel

The following pins are available: 3/8x10, 3/8x11, 5/16x14, 5/16x18. If you want a specialty pin, PM me to discuss.

Each set will consist of 4 parts, 2 in diameter X, and 2 in diameter Y. Each part will be drilled and tapped through, and you install your own pin in 2 of them. The reasoning behind this is if you ever need to modify a mandrel, just heat up the pin and pull it out.

The preorder price for the 4 part set is $249

This gets you 2 diameters ready to work, and probably outlast you. The standard diameters are .836 and .843

If you want custom diameters, add $25 to your order to account for the setup charge.

We will make these for any joint pin, and will warranty them for two years. If you lose more than .001 diameter during two years, send back for free replacement. This only applies to wood sandpaper. If you're using aluminum oxide or diamond grit, that will not be supported (aluminum oxide will probably not wear it out, I'm just being as transparent as possible)

Who else warranties their tools in this industry?

These are 100% made in America, with US steel and master workmanship.

You cannot lose.

The giveaway works like this: if all 10 spots are paid by this weekend (12/13/15), one person will be refunded their purchase price and receive their mandrels free if charge (shipping and custom charges still apply)

If all spots sell by this weekend, I will also start another thread. The first 200 replies get another chance to win a set of mandrels for themselves.

The lead time on these is 21 days to ship, so I'm just missing Christmas, but it should still make for a happy New Year!!

This pricing is only available for the preorder. It increases when they retail.​

The tolerance is within a half thou of requested diameter. Please PM for any customizations


Spots sold:

If my 6th grade reading comprehension still works it is a Rockwell hardness
HARDER than carbide.

Well if you can make steel harder than carbide then I am not quite sure why the tooling industry isn't doing away with all that carbide tooling and going back to steel..lol The point of clarifying the material is so people can make an educated decision. The steel mandrels have been done before and if you do some searching you can find out the results.


Carry on.

I'm only asking because tapered is usually preferred.

Tapering is an option. They cost more money. Everyone clamors for bottom dollar pricing. If someone can beat the price on these mandrels and taper them, with a warranty at all, and a reputation as solid as I have selling on here, please do so.

$249 for a full set of American-made mandrels is stupid cheap, Merry Christmas.

You can absolutely harden them. Go to a steel treater and pay $$$ to have it done. I'm doing that. The results are fabulous. That's why I'm warrantying them. They won't break down.

These aren't just tool steel turned down and sent out to you.

I am not debating whether you can harden steel, obviously that is a given. As long as people know that they are made of tool steel not carbide then people can make there own assessment.
I wish you best of luck with your sales.

I don't clamor for bottom line pricing, nor am I trying to antagonize you. I am simply asking a few questions that most would want an answer to. How much extra is tapering and custom sizing?

They're made of a very nice 4140 alloy, with an excellent finish.

You also get 2 diameter sets for around half the price of 1 diameter set anywhere else.

High abrasion resistance, very wear resistant.

As stated in the post, $25 for custom diameters.

I haven't measured the time to adjust for tapering, but it can't take long so I'll just say $15.

I know you don't come in haggling on pricing, but you are in the minority on this site and you know that.
 
Have these been tested and how? All lot of knife makers sand/grind high rockwell above 60.

I was under the impression that 4140 is normally only hardened up to 40 RC, if hardened at all from its normal 20RC state? It's a great steel for fast machining production part nests and such but I would rather suggest an A2 if you want to bring them up to 60RC. jmo.
 
Is it being case hardened and then re-ground?

Is Thompson rod not good enough for this application? Tommy D.

If you read this and can't figure out that they are NOT carbide - you need to return
your 6th grade diploma.

Thanks, ha!

They are steel, but gas-treated to be a better product in this case, from a cost and reliability standpoint. The only things that will hurt these mandrels are carbide or diamond-grit. The gas treatment we are using has given us over 60 hardness every time. It may not be normal, but it's working.

The reason this type of treated steel isn't readily available instead of carbide is because it requires intervention from a third-party, and it costs more.

I have tested the one prototype with various papers at slow and high speeds, with lots of pressure. Diamond-grit hurts it. Otherwise, not a scratch.

I just happen to have the right connections to get these out to you for little money. If you are stuck on the marketing of "uh oh, it's not carbide, so it must not be good", that's fine. You will just miss out. Thanks for all the questions.

If you want to make your own, instead, then I recommend you go do some homework on the material properties and the steel treatments available to figure out the combination we are using. It's great.


$249 for 2 diameter sets of mandrels. Backed by a warranty. Or go pay $500 for 1 set because it says carbide.

Have a great day!
Patrick
