Bigman Posted February 23, 2006 Report Share Posted February 23, 2006 Today having a day of at college and being VERY bored i decided to havea go at building a whole frame on solid works, I am looking into getting a custom frame made sometime in the future and have had ideas on the geometry that i want for the frame, and after riding Adam Reads KOT i wanted a rear disc mount, preferable able of running a 200mm rotor for uber power.This is what i produced today:[attachmentid=2751][attachmentid=2754][attachmentid=2752]And the best bit of the design, the +40mm rear disc mount:[attachmentid=2753]Hope u guys like it.....Adam Quote Link to comment Share on other sites More sharing options...
Ali C Posted February 23, 2006 Report Share Posted February 23, 2006 lookin good big dude!!I aint too keen on the looks of the dropouts, but if they work who cares!Whats the programe like to use? and is there anywhere I could poss download it?

Rich Pearson Posted February 23, 2006 Report Share Posted February 23, 2006 Not trying to shoot you down immediately, but 200mm disc........................... I'd say that was excessive to the point of inefficiency........... But don't even try and get me to explain it. Frame looks pretty damn good though, reminds me of the old woodman frames.Rich Quote Link to comment Share on other sites More sharing options...

Walleee Posted February 23, 2006 Report Share Posted February 23, 2006 BB shell looks funny, but good work man.Solidworks is a gift to use, once you've got the hang of it. Like any CAD program, if you've used another before it's hard getting used to solidworks. It works kind of in the same way as pro-desktop if you've ever used that, but solidworks is miles ahead in terms of functionality and just general features.It's also pretty nice being able to produce a 3d part, and by clicking a few buttons solidworks will automatically generate the 2d drawing on it's own...It's available for download off E-mule.

wilky_mod_legend2 Posted February 23, 2006 Report Share Posted February 23, 2006 I use prodesk top. i've made a booster on it at school, wacked it into cad cam machines, but only could make it out of wood not much good, but its a good program, that frame looks sweet really like it nice work son!.CheersWilky Quote Link to comment Share on other sites More sharing options...

Solidworks is much more detailed, you'll get a general shape outta prodesktop but nothing regarding geometry and such. With solidworks you could make the tubes a certain material and get the weight of it, also see it's weak points with stress analysis(to a degree), and render it nice and shiney n pimp.....

dave33 Posted February 24, 2006 Report Share Posted February 24, 2006 (edited) i use auto desk inventour pro 10its 5k to buy the program you can does stress analysis on it,far better than solid worksbigman is that an assembly drawing ?edit yes i see it is now Edited February 24, 2006 by dave33 Quote Link to comment Share on other sites More sharing options...

You may remember the removable one my leeson is specced out with, which sends the stress from the disc down into the BB shell. the frame has definately proved its strength, seeing as how the disc caliper actually snapped before the frame has even shown any signs of weeknesses. But yeah, other than that, looking forkin' pimpin'! Rich Quote Link to comment Share on other sites More sharing options...

Richwhat are your views on twin disk mate? i'm considering going that way but haven't riden a stock dual disk. have disks now got to the point where they are better than a great maggura with coust pads and a decent booster?nice drawing bigman Quote Link to comment Share on other sites More sharing options...
Bigman Posted February 24, 2006 Author Report Share Posted February 24, 2006 The frame is made up as an assembly, this is so that if i wanted to vary little bits of the geometry for example the chainstay length i do not have to vary lots of measurements, all i have to do is open the chainstay file and change the length to what i want, it is the same for all the other parts too I need to refine it slightly, i got some measurements wrong on the disc mount, so i have re-done them at home, i also want to make the chainstays again with some 4 bolt mounts so that it looks more like the frame that i will hopefully get made.Iolo: The dropouts do deffiantly look heavy, the initial plan is to get it made out of aluminium, if this is not possible i may have to change the design so that it can be effectively be made out of steel.Glad u guys like it though.Adam Quote Link to comment Share on other sites More sharing options...
tank_rider Posted February 24, 2006 Report Share Posted February 24, 2006 Is solidworks the fully featured package, or is it a cut down easy to use version of a full tier 1 package, like solidedge is to Unigraphics?Looks good Bigman!Are the tubes hollow? as if they were you could probably get an idea of the weight by getting the volume used and the density of commonly used frame alu.Also do you have a shot of underneath the bb area, as i'd be interested to see the detailed design on that. What was your thinking about how that area would be made? single chainstay and bb yoke? or seperate parts welded? Just a couple of things to get you thinking, thats all Quote Link to comment Share on other sites More sharing options...
flange Posted February 24, 2006 Report Share Posted February 24, 2006 I used to use double discs on my bike but hit a number of problems with ita) hydro discs are a pain in the arse if you have to take wheels in and out a lot. Forget the spacers when its in the back of your car and its new bleed and, if they're hope, new pads as well I kept bending discs as I side-hop better to my left. c) I couldn't get them to bite as well as a maggie. Got pissed off in the end and put a maggie on it. Nice frame, had the opportunity to get some made up recently but needed to do some research. Hence I'd also be interested in where to download the software Quote Link to comment Share on other sites More sharing options...

tank_rider Posted February 24, 2006 Report Share Posted February 24, 2006 Glad you did it using hollow tubes, tis far too easy to just use solids And to get an idea of the weight, there should be something in there that can give you the volume of material used, then its just a matter if using the density of alu to get the rough weight. Will give you a reasonable ball park figure to see how thick the tubes need to be etc to get a reasonable weight. Quote Link to comment Share on other sites More sharing options...
Walleee Posted February 24, 2006 Report Share Posted February 24, 2006 Anyone want to sitck up a link as to where I can download Solidworks.You won't get it off a website, I said above it is available from Emule.Glad you did it using hollow tubes, tis far too easy to just use solids And to get an idea of the weight, there should be something in there that can give you the volume of material used, then its just a matter if using the density of alu to get the rough weight. Will give you a reasonable ball park figure to see how thick the tubes need to be etc to get a reasonable weight.All you have to do is specify the material for each part, 6061 alu is in there with the density, young modulus and all it's properties. It's so simple even I can do it! Quote Link to comment Share on other sites More sharing options...
tipsy Jock Posted February 24, 2006 Report Share Posted February 24, 2006 what are your views on twin disk mate? i'm considering going that way but haven't riden a stock dual disk. have disks now got to the point where they are better than a great maggura with coust pads and a decent booster?nice drawing bigman I had twin disk for a while Tom, once you get used to the spoke wobble they can be good, i had an avid on the back and that was immense in terms of power, i found it hard to tell when it locked though. Still prefer maggies i think, although saying that i'm very tempted by dual disk and a kot for my next frame. Quote Link to comment Share on other sites More sharing options...
Will Arnold Posted February 24, 2006 Report Share Posted February 24, 2006 (edited) nice designs there bigman, allowing you to run a tiny caliper and a big disc, a good idea imo i think double disc is the way forward. i had my megamo set up with front and rear avid mechanicals, it absolutley immense brake power wise!!! shame the frame couldn't stand up to the stresses i reccon mike bike would make that frame for you. or possibly leeson if you wanted steel (which i think is the better option for finding out where the main stress point of a disc bike are, as its re-weldable )Will Edited February 24, 2006 by WILL ARNOLD Quote Link to comment Share on other sites More sharing options...

It's not 100% accurate as it depends on the internal structure of the metal your using and the mesh size you input to the software, but it will give you a general idea........
