i'm also trying to outfit my uncrashed bike with sliders. i've read the thread but i've still got a question. the custom made ones are cool, but i'd like to make my own for far less than 65 bucks. so far i've got 2 three-inch pieces of delrin/acetal rod ($6) and two long 10mm bolts ($5). i don't have any examples to inspect up close, so my question, for those who are more familiar with slider designs, is: if you drill a hole big enough for the wide end of the bolt (and the 17mm socket that will tighten it) most of the way through the plastic rod (say 2.5 out of the total 3 inches), and then continue all the way through the last .5 inch of plastic rod with a narrower hole big enough only for the shaft of the bolt (this narrower hole goes against the frame), can you just tighten the engine bolt against the plastic of the slider? i'm not sure if this is how other designs do it. does anyone know if it would be stuipd to have an engine mount bolt tightening into plastic--of course with a stainless washer under the bolt head. the delrin stuff seems pretty high density, but i'm now engineer. wish i could draw a picture, because if this works it is very easy to do and much cheaper than 65 bucks...and it doesn't look bad at all.
