Just wondering why you went with 5 bolts when a normal SCS with 4 is more than strong enough for anything. I'd like to 1.) see a fork long enough to work with the 5-bolt SCS and 2.) see a regular SCS with either broken bars or a broken fork. Doesn't happen very often. Barely at all.
I would suggest making a 3-bolt SCS with either 6mm bolts or even 7mm bolts, would be beefy, tight, and lighter and stronger than a 5-bolt SCS with either 5mm or 6mm bolts.
1. This SCS is only 4inches tall so it works with all forks .
2. making a bigger bolt only lessens the chance of stripping
3. 5 bolts spread the pinch load more evenly across the clamp resulting in a better clamping device.
4. If you put bugger bolts in the clamp would be bigger making it heavier.my prototypes were 1/16 inch bigger all the way around . When i made the final product I removed that 1/16 inch and moved the bolts in closer and reduced the weight by 60 grams.
5. Make a 3 bolt SCS and weight it with big bolts in it and let me know what it weighs. I did one in prototype 3 bolts 7mm and the full size SCS clamp weights in at about 330 grams . My clamp weighs in some where around 230
6. I made the tolerances closer in our clamp so that you dont have to over tighten the crap out of it to get it tight.
7 . I have seen 2 broken sets of forks at my local park in the last 2 months
