The first task we tackled in class was to determine which which set of shears worked best for each student to cut double-thick cereal box chipboard. To my delight nearly everyone had strong opinions about the best and worst. I’m so glad I did this as most of the class prefers a pair that I don’t really like and they hate my favorite.
However, I was not surprised to hear their disdain for the #1 pair pictured above. These are your basic cheap-o-always-on-sale craft scissors and they are generally awful for anything other than opening bags of chips.
#2 are an older version of the Fiskars 9911 “Softouch Multi-Purpose” scissors. Even after years of use in my studio these were still a strong favorite.
Though the #3 Fiskars 12-9936 work great for certain things (Lexan for example) I think the blades are just too short to be efficient for the task of cutting cardboard.
I really like the #4 Fiskars 12-7927 “Titanium Nitride Ultimate Craft” scissors. Like the #2 and #3 thease are a “Softouch” spring return set of shears. They feel good in my larger than average hands so I was concerned that they would be too big for the students but they seem to love them.
I thought that they would also love #5, the Fiskars “Premier Quick-Release Multi-Snip” but for reasons I still don’t understand, they hated them. I’m going to leave them around the class room and see if I can catch anyone using them. They are a little smaller than #4 and seem to have a little bit better leverage due to curved blades. Perhaps this curvature is what they don’t like.
#6 was also initially panned by my young reviewers. These very thin blades tend to flex considerably when cutting thick material but they do work well for trimming little bits of the edges. #8 is basically the same set of blades molded into “Softouch” handles.
The #7 Clauss blunt-tip 6″ trimmer was by far the favorite. They are wicked sharp but also fit smaller hands the best. They are a bit strange in that they have very coarse serration close to the pivot which can leave a ragged edge on one side of the cut but most of the students don’t find it comfortable to open the shears that far so it hasn’t been a problem. I ordered two more pair for the class. As for myself, these shears don’t fit my hand very well and I prefer the spring-opening action of the rest.
Items #2-4,6,8 can be purchased at widgetsupply.com (excellent prices and service).
Items #5 and #7 are from McMaster-Carr (items 3512A21 and 3610A12 respectively).
I found item #1 in the bottom of a forgotten box of glitter and pipe cleaners. A few days into the class the handles broke and we threw them away.
I’ve spent perhaps 150 hours working on this in CAD and less than 30 in the studio prototyping. Once all the patterns are printed and stuck to the double thick cereal boxes I think my students will have a shot at building their own in 12 hours of class time.
Materials include cereal box chip board, corrugated cardboard, wood dowel, hand-rolled paper tubes, recycled #1 plastic sheet, and brass grommets. Hot glue and quick set white glue are used for bonding as well as spray adhesive to mount the patterns. Tools include scissors, utility shears, snap blades, flush trim side cutters, sand paper, and a pull saw to cut dowels and paper tube. Class begins on Monday.
I finally have a complete design. There has been a lot of back and fourth between CAD and studio: design an element, build a prototype, redesign, tinker, second prototype, sketch, think about it for a while, third prototype. So even though I have yet to build a complete clock I do have some confidence that it will work.
But first a vacation back to the Fatherland to celebrate my Dad’s 70th Birthday!
In December of 2011 my UT colleagues and I collaborated with artist Diana Al-Hadid to fabricate a large scale sculpture commissioned by UT Visual Arts Center. I learned recently that this sculpture, “Suspended After Image,” is featured on the April cover of Sculpture Magazine. The portion that we fabricated with our CNC router is the bluish “cloak” on the left which I also posted about here and here. Hook’em!
Knowing my interests, my friend and remarkable scholar, Dr. Stephennie Mulder sent me the image of the gimbaled censer above. The link to the British Museum (which seems to be dead now) stated that the gimbals keep the incense cup from spilling its contents while swinging but this seems overly fussy to me considering the centrifugal forces of swinging itself solve that problem.
Another site suggested that these type of censers were used in games and rolled from one guest to another. I suppose this would work if it were a very low impact game but any amount of velocity or impact and I think the host’s carpet would suffer some damage from errant embers.
The description of “hand warmer” makes a lot more sense to me. In this case the mechanism would function perfectly. Unfortunately, I can’t confirm that the Walters object is also gimbaled though it must have some kind of suspension for without it the orb would certainly be too hot handle with bare hands.
All these pragmatic issues aside, both of these objects are virtuosic expressions of master metal smiths and are a delight to they eyes. What a pleasure it would also be to hold one of these in my hands!
