Sanding Mandrel preorder and giveaway! Better hurry or you'll miss it!

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!

My tendency to be a smart as$ aside, perhaps it is a good thing that Canadian Cue
brought up the carbide/not carbide issue. It led to some info of interest to many that
I wouldn't have known otherwise.

Sure, I'm always happy to answer any questions.

I'm trying to give a couple complete sets away, I hope people have interest. 80 more hours or so.

Thanks for that kind assessment of my comprehension, yes I did read all the way through. My point was to emphasis the fact that these were not carbide. Having built myself a set and being a machinist by trade I do have some experience on this subject.
As optimistic as ideologist may be about his mandrels I do question his facts and by being redundant about the point that they are not carbide was to maybe help those who may not be aware of the difference to maybe do a little research. And as you pointed out, this did lead to more discussion about his choice of material which was my objective to begin with.

Which facts do you question?
 
If there is no down angle on the butt piece, how are you going to sand down to match the face diameter?
 
In all fairness, the OP did say "The lead time on these is 21 days to ship" in his original post on 12/10/15. You should probably PM to check on status depending on your order date.
I look forward to hearing reviews about the product.
