Artificer Brass hinged cantle sporran review

[Panache]

Or just clip it to the brass rings on the back of the sporran. I don't see any reason why not to. I can't imagine what you would put in your sporran that would be so heavy as to cause the brass to break from the strain. I've worn a chain belt with mine in this fashion many times and never had a problem.

Matt,

I don't think it is a matter of weight. It is my gut reaction to having the metal clips linked to just on brass loop each. It seems to me that it would put more pressure at one particular point of the top of each of the brass loops that would over time weaken and break. Whereas the leather strap going through both of them distributes that pressure. But I am not an expert so I can't say for sure.

Hey is there a kilted metallurgist or structural engineer in the house? We need some help here!

Also giving the matter some thought, I think the clicking/scratching sound of a metal clip on those brass loops would be unpleasant!

Cheers

As a matter of fact, yes, I'm a licensed Professional Engineer in structural engineering.

Hmm, the yield strength of brass is at least 18KSI. Assuming that the ring is about a 3/16" diameter brass rod, it has a section modulus of S=0.000647 inches cubed. Thus, the moment strength is approximately 11.6 in-lbs. If the brass ring stands off the back of the cantle by about 1/4", then technically the clip should be able to pull about 46 lbs laterally on the top of the brass ring before it reaches a permanently yielded failure mode (i.e. permanently bends the ring at the root where it is attached to the cantle).

Of course, cyclical stress analysis should be done too, in order to check long-term fatigue issues, but let's not go overboard!

Honestly, Matt is right. Regular use shouldn't bend it with it just clipped to the top. But you may find wear marks and scratches from the harder metal of the clip marring the softer brass over time.

Tobus,




My favorite hiking staff for birding had a top made of a deer antler attached to the wooden shaft by a really thick bolt that was glued with two-part epoxy linking them. After only a few years of use I was shocked when walking along there was a soft "tink" and the antler top toppled off the shaft. The years and repeated stress had taken their toll and the metal failed at the joint without any sort of abuse.

So I think that the softer leather strap equally supporting the weight of the sporran and contents from both loops is probably a better long term choice for my investment.

Cheers

Beautiful sporran and you wear it well! Congratulations to you on a fine acquisition and to Scott on yet another masterpiece.

I have 3 sporrans from Artificer and one on order. They all are truly works of art, and the quality is unsurpassed. Worth the wait, worth the cost, simply the best.

Congratulations again, Jamie! Scott's work is truly amazing and even more so in person. Enjoy your new sporran!

Cheers,

Thanks all!

I have man-bag envy. :crap:

That's easily solved, you know.

I have 3 sporrans from Artificer and one on order. They all are truly works of art, and the quality is unsurpassed. Worth the wait, worth the cost, simply the best.

The fourth one will push you over the top for the current record for most commissions (you're currently tied for first).

Congratulations Jamie on such a fine aquisition. From your photos above it is great to see the versiltility of the sporran with a range of dress styles. I have a brass cantled sporran on order from Artificer also and from your photos, I agree, it's worth it!
