welding steel base or just getting aluminium extrusion

I know you are going on other designs but all this generally means is.... someone that isn't an Engineer or a fabricator came up with a design, made it and it worked, and that then sets a president others follow. That does mean mean its good design all it means is someone proved it worked. In the same breath if that design had been done by someone with a lot of experience then that would have been the president and far easier to get a lot better result.

You'll not last long in the DIY CNC world with sensical observations and comments like that ;-)



Listen to what sluppit has said.
I took one look at your design last night, and immediately wondered how many tonnes you were planning on having on it, and why it wasn't using full length sections on the long edges. It looks to me like you've just kept adding bits, without really thinking about why you would need to add them, and ended up with an over complicated design.

it wasn't complicated until i finished in solidworks and then reality hit :)

if it was cheap enough to make mistakes then sometimes its good to make them before getting the right advice from here, That way you get to learn what works and what dont work but unfortunately this is a hobby that is just too expensive to just ignore good advice. I don't think dean realises just how much i appreciated all his help from emails out of his own time which i have kept and still read them :)

£1580 for the one you have provided mate so still expensive

Whats with the attitude you keep giving me? don't want to sound like like a twat to you and i do appreciate the time you are giving to help but i didnt ask you to make or do anything for me. i have said many times i am going the aluminium profile route because either way its going to cost me around £500 for the material and then there is no way someone will do that frame for me for under £500 and i don't blame them. the design you shown me looks alot more simple then mine and you said to use 80mm instead of 90mm so that should of been cheaper. The guy who has quoted me is off facebook that got recommended to me, so i sent him that as a rough example and he quoted me £1580 without the extra bits i would of added on. like i said earlier because im not as skilled as most of you by the time ive payed someone to do it and bought all the material its going to cost me almost as much as what the aluminium profiles is costing. the whole point of going steel is because its cheaper and i know its more rigid but the aluminium also has an advantage for resonance so either way i choose its going to cost me the same or maybe a little more.

again i don't mean to sound harsh but i didnt ask you to send me any files or do any work and i already said a few times im going with aluminium but you keep posting with more steel advice :)

My mistake. Offending posts removed. I wish you luck with your build.
