UK_SPAWN Posted June 25, 2013 Report Share Posted June 25, 2013 Anyone know of a place that build frames and could build one to your own design? Cheers, Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 25, 2013 Author Report Share Posted June 25, 2013 I guess it would also cost a lot Quote Link to comment Share on other sites More sharing options...
Jake. Posted June 25, 2013 Report Share Posted June 25, 2013 The two that are spoke about the most on this forum are jaf bikes and Marino... Marino has longer waiting times, costs less, jaf is much quicker and costs more. Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted June 25, 2013 Report Share Posted June 25, 2013 (edited) marinobikes.com (250 usd n+65 usd shipping) jaf(jaf-bikes.co.uk? i guess) aprox.00-400 gbp tritonbikes.com around 600 gbp + shipping in raising price order Edited June 25, 2013 by FamilyBiker Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 25, 2013 Author Report Share Posted June 25, 2013 (edited) And is that to a design of your own, or one of there frames to suit you/geometry? Ill post some 'preliminary designs' (doodles) in a sec. Cheers Edited June 25, 2013 by UK_SPAWN Quote Link to comment Share on other sites More sharing options...
Revolver Posted June 25, 2013 Report Share Posted June 25, 2013 Price varies depending on your design. If you want 3 brake mounts, a custom tensioner, bottle holder, flag mount, side stand and CNCed name badge this will obviously cost more. 1 Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 25, 2013 Author Report Share Posted June 25, 2013 This is the idea I had, sort of mixing the M5 monty with a more traditional design. (Use wih rockman carbon fork) Concept 1; Sketch 2; Detail / Exploded view; This would be a hassle but I really like the look of it. I bet I'd have to get a seperate company to do the carbon bits and some place to make a Ti "interconnect". Now I await the "that wont work" lol. Thanks for looking.

Jake. Posted June 25, 2013 Report Share Posted June 25, 2013 (edited) Looks a bit like an adamant a3 mod frame to me, but with carbon bits. I reckon that top tube is way too low down on the downtube, looks like you're going for looks rather than a geo you want as you don't appear to have written a geo anywhere? The first thing people tend to do when getting a custom frame is sort the geo out, then focus on looks. I don't think it'll have much strength at all.

UK_SPAWN Posted June 25, 2013 Author Report Share Posted June 25, 2013 Yeah the idea was looks, I know nothing about geo. Probably around 995 - 1000 wb Im not actually going to buy this, just wondered if you COULD do your own design as I was sketching and thinking "yeah thats nice" and thought id just ask how much it would be for just the "frame" not including the carbon shiz. So move the top tube slightly higher, could curve I suppose. Ill draw some more Cheers Quote Link to comment Share on other sites More sharing options...
Danny00135 Posted June 25, 2013 Report Share Posted June 25, 2013 I bet I'd have to get a seperate company to do the carbon bits JAF would most likely do it Quote Link to comment Share on other sites More sharing options...
dngr2self Posted June 25, 2013 Report Share Posted June 25, 2013 I was quoted around 300 from jaf for something similar to Damon's but different geo. Frame material, paint work and other extras all alter the price though. I ended up skinting myself though so I can't get it now. Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 25, 2013 Author Report Share Posted June 25, 2013 Wow thats really cool I think, design your own frame... I may do it one day, as for geometry I'd probably copy the geo of a frame I know I like, im interested in the look, I like the bike I ride now Thanks lads (and lasses) gave me inspiration. If jaf would do the carbon work too then thats sweet. And the top tube don't have to be Ti, just id like that lol. Cheers Quote Link to comment Share on other sites More sharing options...
dezmtber Posted June 26, 2013 Report Share Posted June 26, 2013 That bolt in carbon part would cost you the most, as it would require many hours making moulds for it. If it could be wraped rather than bolted in. I would take a guess it would come in around the same price as a jaf frame build around £350 Plus the price of a large jaf carbon repair however much that normaly costs. But that bolt in should cost around £1000 as a one off Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted June 26, 2013 Report Share Posted June 26, 2013 How on earth are you coming up with that figure? Sure, send it off to a large firm to knock up a CAD model, run some FEA and produce it to aerospace tolerances and you'll be running up quite a tab, but for someone to create the basic structure, hell, you could do that in your own garage for £100 including buying the kit to do so if you put your mind to it.

UK_SPAWN Posted June 26, 2013 Author Report Share Posted June 26, 2013 Yeah it doesn't have to be removeable, could just use the carbon seat as the top tube, remove that bar idea all together, the carbon would just havto be thicker and be structural. No I wont be making anything myself, I dont even have a garage. .. Quote Link to comment Share on other sites More sharing options...
dezmtber Posted June 26, 2013 Report Share Posted June 26, 2013 (edited) If were designing carbon to those grades it would cost way more than that. You would be going into tens of thousands. I was thinking pay josh a weeks wage plus the cost of materials your well into a grand. Which it would take at least a weeks work to produce a mould and the final product.

ItsAllGravy Posted June 26, 2013 Report Share Posted June 26, 2013 (edited) carbon moulds and dense foam from memory most the cost is in mould manufacture... you certainly don't need a garage to make a cf mould out of foam, basic tools, sand paper and effort and your sorted.... \ am i also missing the point completely of what this piece of carbon is supposed to do other than be a piece of carbon on a bike?

dezmtber Posted June 26, 2013 Report Share Posted June 26, 2013 Depends on the quality of the final mould you want. The moulds I have made start by making either a foam or wood model of the part you need. Then take a mould from that. Rub that mould back flat. Then take a second mould from that, rub that back. You will have a perfect flat surface with no high/ low spots which you can make your final moulds from. Then make your final mould Which you use to produce your carbon parts from You can cut out the first two moulds. But all the carbon parts you make from that mould will need rubbing back to flat. Which takes time. If your only making one part that's ok. But even that way you are looking at One day to make the part, then another for the 1st mould and Another day to mould the carbon part. Followed by another day to flat the carbon resin and laquer it. Making moulded is easy its the flatting off resin that takes ages That's still 4 days work .

UK_SPAWN Posted June 26, 2013 Author Report Share Posted June 26, 2013 am i also missing the point completely of what this piece of carbon is supposed to do other than be a piece of carbon on a bike? The idea is to remove the top tube and have a single down tube, but brace with other materials, so I had the idea of a removable top brace/seat/piece of carbon on a bike. But its also the top tube, buy now im thinking it shouldn't be removable and should be wrapped in carbon and be furthur up, have 2 brace pints on top instead of one... its a sketch, that were discussing the cost/possibilities of actually making it (not that im making it or having it made). But if I made a frame, thats how id want it to look... hope that clears things up CheersMay practice with carbon though, start with headset spacers see how that goes.

UK_SPAWN Posted June 26, 2013 Author Report Share Posted June 26, 2013 New sketch: Doubble braced down tube, braced furthur up. Larger gussets on head tube. More to the point, anyone actually like the design? Cheers Quote Link to comment Share on other sites More sharing options...
ItsAllGravy Posted June 26, 2013 Report Share Posted June 26, 2013 (edited) I like the concepot yes in theory but idk... surely though in a ideal world carbon is not the answer... its very weave dependant on directions of strength and you are probably going to have little idea of the materials flaws and subsequently manufactures are going to have little understanding of the real world application of a trials bike and the stresses applied to it... even if you spent thousands it would be pouring money down the drain imho. why is it always carbon... surely Ti is a much better material.... in a ideal world surely a skeletonised Ti frame is way to go for strength rigidity and weight is it not? and you could design and have fabricated a sick Ti brace for less than a CF one. idk im not a structural engineer but just sharing my 2pence...

UK_SPAWN Posted June 26, 2013 Author Report Share Posted June 26, 2013 (edited) Well if u look on the very first picture the brace is made from ti, but from comments I recieved I was unsure what would be better, the carbon was just for a seat, and too look nice. The carbon "undertray" I thought would solve the problem of the bash guard mount going through the frame (as there is no mount as its adhered to the frame) And I made the brace removable as I didnt know if Ti could be welded to ally, and assumed not.Next step is to 3D model it in 3ds max.

ItsAllGravy Posted June 26, 2013 Report Share Posted June 26, 2013 (edited) if its structual my couch engineering knowledge would lead towards Ti for brace and carbon for bash as you said it wrap locking on and even the potential to brake under ridiculous loads would be an advantage for the frame for sure for the bash guard... and Ti does weld to anything very well and tend to make weak joints if i remember correct...
