Canardweb Posted March 15, 2011 Report Share Posted March 15, 2011 (edited) hello, I'd like to make myself a bashring, so I would draw it on CATIA, then cut it with a plasma cutter, but I don't have all the dimensions I need. I know the outer diameter is 88 mm, I know the width which is 3mm, but I don't know the inner diameter where you actually put the crank in. Does anybody knows it? Please help. Thanks Tartybikes gave me the answer! 35mm that is. Cheers anyway I have now finished designing it on CATIA. Here is a pic. I'll have it tomorrow if everything goes well. Tell me what you think!

monkeyseemonkeydo Posted March 15, 2011 Report Share Posted March 15, 2011 Would you like one? I could make it of course! Looks good though I think it would look better if the lightening holes followed the curvature of the ring rather than running straight.

Canardweb Posted March 15, 2011 Author Report Share Posted March 15, 2011 (edited) Looks good though I think it would look better if the lightening holes followed the curvature of the ring rather than running straight. Yes I thought of that. I am only doing it as a simple prototype though. I'd like to keep the geometry simple for the program first! Also I'd like to keep the outer edges quite wide so they resist better to shocks. I I just use the shape of the outer edges, I'll have to change the geometry in the part. That means more lines in the Plasma cutter machine program, and more mistakes that can be done. Edited March 15, 2011 by Canardweb Quote Link to comment Share on other sites More sharing options...

AdamR28 Posted March 15, 2011 Report Share Posted March 15, 2011 Unless it's gonna be steel, that will deform pretty quickly... you need some sort of 'bracing' in the big hole. Quote Link to comment Share on other sites More sharing options...
Canardweb Posted March 15, 2011 Author Report Share Posted March 15, 2011 (edited) Yeah would be great if you could!! How much do you want for one?? Just shipping honestly. I don't do it to earn some money man. Cool beans. What material are you going for? Steel deffinetly but I don't know which one yet... Unless it's gonna be steel, that will deform pretty quickly... you need some sort of 'bracing' in the big hole. Bracing? What do you mean? This is another project I have in mind. I would cover it with carbon fiber to make it more resistant. Alone, this rim is 382 grams. With carbon, it would be like 500 grams maximum!

isitafox Posted March 15, 2011 Report Share Posted March 15, 2011 Nice one, PM me wen you've done it and I'll get some £$ sent across for you. And what I believe Adam means is change the design a little so it's more like this I apologise for the ropey paint drawing!! Quote Link to comment Share on other sites More sharing options...
thispartisrequired Posted March 15, 2011 Report Share Posted March 15, 2011 Unless it's gonna be steel, that will deform pretty quickly... you need some sort of 'bracing' in the big hole. If it was braced you couldn't open bottles with it as easily though Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted March 15, 2011 Report Share Posted March 15, 2011 And what I believe Adam means is change the design a little so it's more like this Exactly, such as: http://www.tartybikes.co.uk/bash_rings/neon_bow_halfring/c1p11484.html http://www.tartybikes.co.uk/bash_rings/trialtech_titanium_halfring/c1p10557.html Etc.

And what I believe Adam means is change the design a little so it's more like this I apologise for the ropey paint drawing!! I see what you mean. I'll see what I can do. I won't probably do these holes you know. SO it looks more like that: I'll make a visual of yours now. That'll be fun to plasma cut Hopefully, I am not plasma cutting it. (How could I be?) Exactly, such as: http://www.tartybikes.co.uk/bash_rings/neon_bow_halfring/c1p11484.html http://www.tartybikes.co.uk/bash_rings/trialtech_titanium_halfring/c1p10557.html Etc. Ok Adam, thanks a lot.

Canardweb Posted March 15, 2011 Author Report Share Posted March 15, 2011 I'll try to do it tomorrow! But I also have a carbon frame to do. Yokes are done as well as the headtube. Quote Link to comment Share on other sites More sharing options...
isitafox Posted March 15, 2011 Report Share Posted March 15, 2011 No worries, as and when you can squeeze it in mate, just let me know how much you want for the postage and I'll sort you out!! Quote Link to comment Share on other sites More sharing options...
