After finding that Rox antivibe risers (and even other neccesary maintenance parts, let alone "farkles") are now out of my price range, I've decided to make my own. "How is a guy that can't affford the mass-produced end product going to be able to afford a machinist's one-off of the same thing?" someone asked. Well, this and the other custom projects that are sure to follow will take a lot of time, but I have a way. But first to ask my question, "How are antivibe risers constructed?" I see that there is a piece of aluminum that has been turned to go in place of the handlebars. This piece also has a block with a hole where the new clamps are bolted via rubber bushings, to dampen the vibrations. Wait, if the rubber bushings are only clamped between the clamps and the blocks, top and bottom, isn't there a bolt running through the block, transmitting vibrations? That would not imrove one's vibration situation much. So let's say the rubber bushing is actually continuous, througha big fat hole, and it is held in place by the compression from being bolted in and squished. Now the steering would be at the mercy of the rubber, so it can't be too soft now. Let's back away for a minute now. The rubber bushings are kind of neat looking. They remind me of all those cool different rubber bushings you can buy for your skateboard trucks. Here are some favorites: It would be nice to be able to change the buhings out for a different durometer of rubber to find the right level of dampening. The skateboard truck bushings are perfect for that need since they come in different durometers. This assumes that the bushings are not a one-piece that go all the way through the bolting block, though. So does the bolt in fact touch the inside of the block, possibly transmitting vibrations? We will need someone willing to disassemble one of their risers to find out. The way I imagined building one of these was not much different from the way the Rox ones look. The bushings would definitely be skateboard bushing compatible. The bolt that connects the two pieces would have a length of vinyl tubing or the like whose inner diameter matched the outer diameter of the bolts being used somewhat closely, and then the holes in the two aluminum parts would be matched to the outer diameter of the hose somewhat closely. This would give the risers a somewhat preset level of dampening based on the types of tubing material with suitable wall thickness, o.d., and i.d. I could find. I'm sure there would then be a further dampening factor given by what durometer of bushings are used. If the design had the bolts free-floating, that is, if the holes through the blocks are much bigger than the bolts and do not touch, transferring no vibrations, are the bushings enough to keep handling of the steering within a reasonably tight range? So the main question I need answered is, what do the insides of the rox risers look like? Also, are you happy with the handling, or would you sacrifice some of the vibration dampening for tighter handling? Looking forward to any input, including, but not limited to, "you are violating patent laws", "You are an idiot", "here are a free pair of risers for shutting up and keeping our trade secrets from enterprising hobby machinists", "you go boyy", etc... There is a place called TechShop. I hear there are many opening up across the country. Anyway, volunteers get free shop time, which means acess to things like CNC mill and people who know how to use them. Possibly also people who know how to teach me CAD. That is how my broke ass plan to pull off making my own pair of highly specialized and adaptable handlebar risers.
