First shots of the Berserker

Simpson Wong posted this up in Facebook. It is a Bi-Metal design comprised of a 6061 body and 7000 series weight rings. A very interesting concept. I happen to have on as well. It is in my review schedule but Monday, I will post up a Berserker edition of :captured:

Update: YoYoExpert Edition

    Well; I have no actual factual way of knowing ‘why’ they did the rings like that but from 12 years of yoyo modding; I can see one interesting explanation. I used to cut yoyos up alittle and then put in different weighted rings to see how the yoyos would play? < To save you guys a super long story, let's just say, that might have been the 'angle' of their reasoning. They machine the yoyo halves 'to get them close', then they get several of the protos and press in weight rings that increase in increments of maybe a gram per pair. So they end up with say.. 5 protos: 64, 65, 66, 67 and 68 grams total finish weight. They figure out which one their testers decide is the very best of the bunch, and make more weight rings. Instead of making up about 600 halves of an exact, fixed weight; they have 600 halves that could be adjusted to a different weight for whatever reason/performance benefit.
    Also from a Custom perspective; the add in rings lend alot of space for visual tweaking: different colors, different finishes: powdercoating, glow in the dark, gold plating, engraving, advertising, etc.

    So, you can either think of the rings as an: afterthought to increase weight or the result of some deeper thinking that resulted in a Genuine Custom yoyo with 'room to move'.

    Based on the performance of this Companys' yoyos; I would have the tendency to recognize that this maker has a very very solid understanding of making good playing, good looking yoyos. Just sayin

    @ Matt That is very incorrect. Between 6061 and 7075 There is usually 4 grams in difference from one design to another. I think this is a great idea. It gives the yoyo an IGR while concentrating a certain amount of rim weight to the outside. Plus I like the two tone look!

    My guess is that the weight rings are 7075 for durability needed for removal/insertion, not necessarily for the negligible weight difference.

    I wonder how much the rings weigh?

    You have a few spelling and grammar issues you may wan to clear up in this post. I was especially confused by “I every interesting concept.” XD

    I am curious as to why they did not machine it all from one grade of aluminum. 7075 aluminum has a density of 2.81 g/cc, 6061 aluminum has a density of 2.7 g/cc. When I have made Solidworks models of yoyos in the past, the largest weight change that I saw when switching between 6061 and 7075 was 1.75 grams. That was over an entire yoyo. I can’t imagine that adding a weight 7075 weight ring rather than modifying the design to include an integral weight ring of comparable proportions would add much more than .1-.3 grams.
