Guest Posted January 18, 2006 Report Share Posted January 18, 2006 thanks if i add you to msn could you give me some help in the design of it e.g. stress points lol, do you know anything about product design? It's a good idea to do a bit of work yourself....If your having to ask about where stress is in a booster then im not so sure you should be designing one.....

That has an effect on stress and such.Also, what CAD package are you using? Solidworks has stress analysis tools... Quote Link to comment Share on other sites More sharing options...
Caleb Posted January 18, 2006 Report Share Posted January 18, 2006 £3 seems waay to cheap to mee, it would take a good hour or two to do the program, then labour cost, and material.i think your best bet would be to just take him in a booster for him to get measurements off, a drawing would take a lot of time and effort if you didnt know what you were doing, including all the tolerances and radii and diameters etc. Quote Link to comment Share on other sites More sharing options...

I used it at school 4 years ago and I want to see if its much better than solidworks.....Also, the best way of doing it, and I think steve from heatsink has done this too, is to make yourself a wee design out of cardboard, stick it on the bike where the bolts are, and see if it clears everything, if it doesnt, you'll need to cut away the bit that rubs...

B.E.A.U Posted January 18, 2006 Report Share Posted January 18, 2006 hay mate. erm i may be interested in one of the boosters. could you add me to msn beau_forrest89@hotmail.com and can he anodise other things? Quote Link to comment Share on other sites More sharing options...
Danny Kearns Posted January 18, 2006 Report Share Posted January 18, 2006 Well for starters it definatly has to be 4 bolt.I would also like it to be similar to the echo control brake booster with alot more tyre clearance, because i cannot run my control booster because there is not enough tyre clearence. yeh if its to my taste i will take one off you for 5 posted defo. ( anodised green - like the new zoo bars colour).Dan ! Quote Link to comment Share on other sites More sharing options...
tank_rider Posted January 19, 2006 Report Share Posted January 19, 2006 For a start you can't just copy a design, or even just make a couple of tiny changes.Secondly, unless you know what your doing with stressess etc, then please leave the boosters to the experts. It's easy to make a stiff booster, its another thing to make one that is a reasonable weight with it. I know Steve isn't making a fortune from each booster he sells, the majority of the price (something around 75% probably) is made up by the manufacturing costs. I know for a fact that of all the boosters I've used or seen, Steve's are the best quality, both in tems of design and manufacturing. Also if you're going to be setting up in competition with Steve, I highly doubt he is going to give you a hand in designing a product, that just wouldn't be good business!! Oh and depending on what degree your d&t teacher did, he may not have any more knowledge on the subject of stresses than you do!It looks like your after making a quick buck, but without caring about how you do it or what your customers get, please please please stop right now before you give yourself a bad name and annoy people.

OD404 Posted January 19, 2006 Report Share Posted January 19, 2006 Also, what CAD package are you using? Solidworks has stress analysis tools...I'd be a little wary of the results you get from the built in stress analysis tool in Solidworks. From my experience it has been optimised for speed as opposed to accuracy which will lead to errors within the results. Also, because you are unable to edit the size of the mesh used in the analysis, there is no way to improve the accuracy.For anyone serious about doing stress analysis with Solidworks, I suggest you look into obtaining a copy of ComosWorks, which will provide greater control and accuracy.But don't forget, all these programs by their vary nature, carry some level of inaccuracy.In terms of the designing a booster, there have been numberous posts in the past in which the ideal shape of a booster has been discussed, a quick search should yield some good information.

nmt_oli Posted January 20, 2006 Report Share Posted January 20, 2006 The arch is still wayyyy to low, do some measuring!I don't have a problem whith this guy making his own boosters, as long as he doesnt just copy someone elses design, but even if they are cheap, they wont be as good as some others, you get what you pay for! and as mark said, there likely to be a lot more than £3, materials are likely to be almost £3 per piece, depending what grade alloy your using.

mat hudson Posted January 20, 2006 Report Share Posted January 20, 2006 move the arch up and make it so its an "I" beam rather than an "L" beam. Quote Link to comment Share on other sites More sharing options...
OD404 Posted January 20, 2006 Report Share Posted January 20, 2006 My sister could do a better jobBut if your sister is anything like you, she could probably do it better than me I'd revise the thickness of your design, if it is to be made from aluminium I'd say it has nowhere near enough material in the right places for it to be effective.As for the cross section, an I-beam would be better in theory as material will be placed at the area subjected to higher stresses. However the cross-section design that has been put forward (probobly un-beknown it its creator) is not that bad either. Materials such as aluminium and steel work better in compression than tension (in theory), therefore the reinforcent requirements for the top edge are less than those on the bottom edge (top edge will be in compression due to bending, bottom will be in tension).A picture can tell a thousand words, but dimensions would tell us so much more...
