Yes, that's precisely what you're doing. But by bending the wood that much you'd put so much stress on it that chances are it's moth worth it, but hey, I've been wrong plenty of times so the only thing you could do for certain is try it and find out!

Also, yes, all the new wikis need to be updated, just remember anyone with a scioly account can edit it

Yeah, it might not be wise, but by reinforcing the stress-point with more wood and laminating it, it might altogether get rid of the need for a bulky base.It might be worth a try. The only problem is finding 3/16" bass longer than 24" so it would probably have to be ordered online.

Hmm... Last year my lightest base that held full was .33g, so I wouldn't call the bases 'bulky'

Bass certainly would bend better than balsa, so that's a good plan, but I don't see any reason why a base for these j-hooks would have to be bulky in the first place, I think it could easily be lighter than mine from last year.

Now, that being said, bending the wood itself would do a lot to remove failures at the base due to bad glue or not enough glue area, so it's really all up in the air till someone tries it out.

So basically summing the J-Hook up; The base can be anything that works?

[iwonder]

Sure, as long as it fits! I don't see why there would be any limits.

So excited for this upcoming season, the new J-bolt solves alot of limiting factors that were preventing booms from scoring higher with the past bolting system (easier mounting, so theres almost no way to incorrectly mount; booms won't slip off of the mounting wall, etc.)

I get the fact that the pin will prevent the base slipping off, but I think it'd be harder to align the boomilever parallel to the ground right?
What're your thoughts on how the new J-bolt will allow for higher scores?

Now I'm confused. How did booms ever slip off the mounting wall? And yes, it seems like it will be harder to get the right alignment :/

Any chance they will define the the hook for hanging the bucket this year as part of the testing apparatus. We ran into an issue last year, where we went to one invitational, and they had an Eye Bolt, where the chain was permanently attached and we had not designed for this. We had designed the compression members to be just slightly wider then a 1/4" J Hook, and with the chain attached it would not fit though the frame. Nowhere did any of the rules define the size of the chain attached, so there was no way to design for it. This was not an issue at another invitational where they used a J Hook and separate chain. Has this been discussed at all, define this part of the testing apparatus. Thanks

Actually, the rules for last year specifically stated that an eye bolt would be used (rule 4.a, and 4.c), so it was defined...

As for your specific issue, well, there's no rule that says you couldn't remove the eye bolt from the loading block, slip it up from the bottom, and re-attach it to the boom

[S4BB]

We did remove the eye bolt from the Block, sometimes tough at the fist competition for 7th and 8th graders. My point was that if the chain is permanently attached as part of the testing apparatus, it should be defined so that teams can design for it, do you disagree? Thanks
