tank_rider Posted November 2, 2006 Report Share Posted November 2, 2006 Looks quite well made, was it custom layed up, or just made from a sheet, looks like the former to me. I'd like to see a bit more clearance, and if its custom layed up then making it in either a slight L, T or I shape would add to the stiffness withought increasing weight (you can take some material to allow for clearance then). No-one is yet to beat the stiffness for weight of the shimano carbon booster. Quote Link to comment Share on other sites More sharing options...
Clarky Posted November 2, 2006 Report Share Posted November 2, 2006 exactlywhat i thought kyle, new tyre will result in getting the file out or the grinder Quote Link to comment Share on other sites More sharing options...

tank_rider Posted November 4, 2006 Report Share Posted November 4, 2006 what do you mean by an l, t or i shape??? could you explain please then ill try the new shape and see how that works... cheers I'm talking about the cross section of the booster. A simple flat design will twist when enough force is applied to it, even if the force is in the same plane as the sheet. Therefore having some material bracing the out of plane movement will help improve the overall stiffness of the design. If you don't know what i mean have a look at the shimano xtr carbon boosters, they have a slight I cross section. Quote Link to comment Share on other sites More sharing options...
Adrian Posted November 5, 2006 Author Report Share Posted November 5, 2006 oh i get what you mean, iv already done that, you cant see on the pics because its on the under side, basically on the bottom the out kind off sticks out like an out line ill take a pic and show you Quote Link to comment Share on other sites More sharing options...
RobinJI Posted November 13, 2006 Report Share Posted November 13, 2006 And if you really want to make it the best weight/stiffness ratio then make the inside ridge slightly higher than the outside ridge as carbon is better under compression than tension. This ones looking sexy though.Is that the same type of matt all the way though or have you got some different layers throughout it? could maybe try placing the layers at 45deg angles, so that the grain is slightly more fitting to the overall shape, or using some loose fiber matt in the middle layer or two curved round in the shape of the booster. (correct me if I'm being a tit, I'm alot more used to fiberglass than carbon, but i think it still applys) Quote Link to comment Share on other sites More sharing options...
Adrian Posted November 29, 2006 Author Report Share Posted November 29, 2006 well as you may know then, fibre glass is alot stiffer and more ridged then carbon.. but if you flex fibre glass too much its more prone to crack, so what ive done is 2 layers of carbon on top then 3 layers of fibre glass then something else then another 2 layers of carbon, so its stiff but also if i accidentaly like sit or fall on it so it bends towards the frame (if you get what i mean) it wont crack, but in my next booster im going to insert a 1mm sheet of alu for extra stiffness then only use half the layers of carbon sooo it should be just as stiff, if not stiffer and about the same weight still.... well see Quote Link to comment Share on other sites More sharing options...
Ducko Posted December 1, 2006 Report Share Posted December 1, 2006 good job i guess i think custom home made things are always nice i made me bro a tensioner and its worked fine for almost a year now haha spot on! Quote Link to comment Share on other sites More sharing options...
