You'll hafta ask the man who made them. "thumbsup"

We are all lucky to have such a great vendor. "thumbsup"

True, he made great stuff. "thumbsup" I can't wait to get my hand on this Ti badboy....8)
Rowdy, you are not a bad vendor either, your products have last the test of time..... Almost every XR10 has at least one of your mount on it."thumbsup"

I read somewhere these spools are made of Grade 2 material. What's the advantage of Grade 2 Ti over say 7075 aluminum? The aluminum is 60% stronger, much lighter and way cheaper.

I'm of the opinion if it's worth doing in titanium, you gotta use high strength Grade 5. I'm sure if I'm wrong here, you'll let me know.

(BTW, the V1 spools were 6061. This Ti is stronger than that.)

See this link...

Compare Materials: 7075-T6 Aluminum vs. Grade 2 (3.7035, R50400) Titanium :: MakeItFrom.com

The grade 2 Ti is better in almost every strength related areas. However 7075 is lighter and if you normalise all strength properties with weight, 7075 will be "better", but for pure strength, grade 2 Ti seems to be better choice than 7075. We are talking about less than 5 grams difference between 7075 or Ti on a small spool like this.

I am no machinist (I only use dremel ) but I think 6061 is easier to machine than 7075, in the same light Grade 5 Ti is hard on tool compared to grade 2 Ti...

That's a neat chart, but I think you misinterpreted the results. The parameter we typically call "strength" is tensile strength, found low in the chart, and it clearly favors 7075. Note also strength to weight ratio as being huge for the aluminum -- more than 2 to 1. But like you, I don't know how easily 7075 machines. True, the Ti is higher in several various categories, but I don't know how important they are compared to strength and weight.

I keep looking at them in the flyers we get from our tool suppliers at work, I really want a cross slide vise for the house.

FOR THE HOUSE!! - man that would be one HUGE vice. :shock:

FOR THE HOUSE!! - man that would be one HUGE vice. :shock:

Man comes home from work one day and says to his wife "honey I would like a little pu$$y."
She responds "Me too, mines as big as a house!"

Did someone say something aboot a crazy cat lady?

Good point. But i am not sure how much tensile strength the spool is subjected to. I think the most failure (or wear) occurred where the shaft's tangs connect to the spool and it "enlarged" the hole slightly over time causing slop. Anyway, due to the light weight of the Al, where strength-weight ration is concerned, 7075 will triumph every time.

Few more comparison...

7075 vs Grade 5 titanium

The titanium sure is superior material and even when compare the strength-weight ratio, they come close.

6061 vs Grade 2 Ti

Here you can see the new locker is sure a step up from the old 6061 one."thumbsup"

But i am not sure how much tensile strength the spool is subjected to.

The wear around the axle tangs would be controlled by tensile strength and compressive strength. Tensile strength would prevent the two flats from being stretched away from each other and compressive strength would prevent the flats from being distorted.
