Looks good mate.Im a boilermaker,and I think the welds on the Y look pretty fucking sweet.If you wanna get real fussy then maybe on the front of the Y he could have gone a bit slower,less filler wire or had more amperage,but to me it looks like the welder knows his shit.That black shit is normal,slightly dirty ally but even when you clean it well with a stainless wire brush that shit still happens.Happy roosting :cool:

Looks great,Id be happy with that ! Hope you dont mind me asking......just wondering what the wall thickness on the square tube is ? From the radius on the outside of the tube,and the way it has sucked in on the inside of your bend it looks like its thinner wall than 3mm (1/8). Honda uses 3mm so I wouldnt like to go any less than that.Maybe just the pic but thought it was worth mentioning as the last thing you want is for it to fatigue and crack.

those bends are typical of a shs die. the die (mandrel) has has a raised section on the inside that forms the depression you see on our machine i used the square rollers with a pipe die so the depression didnt happen
and with a shs die it doesnt matter what wall thickness it is it will still crush the inside of the bend

Thanks to all for the positive comments and concerns. The tubing thickness is enough to provide years worth of fun filled service. :wink:

As I said before Bob deleted my orignal 14 page thread, I will show everyone pics if (in the extremely unlikely event) it ever fails.
I will do so willingly.

This build has been a learning process from day 1 and I couldn't do it without the good info and direction I've recieved from helpful members. Thanks! :D

the stuz you make me laugh the weld size is relevant to the material thickness

sorry hero, my point was, if you look at the factory welds(at the start of the page) then you take a look at the welds that have been done by reds welder, there is a distinct size difference it the welds.
the oem welds are much fuller and larger and sit prouder and cover a greater surface area, where as reds welds are smaller is size and fill and im not sure but looks to be not as strong as oem(no offence red).

if size is relevant to material thickness(as you stated) then why are oem welds"larger" using the "same" materials?

if i was doing 40ft tables on that i would be a little bit worried.

when you consider oem frames are heat treated after all welding for strength, yet the ones we build are not, i would take the welding size very seriously.
if i were to do a af build, i would put two cuts down the top of the y section that the front frame sits into.10-15mm cuts with a gringer, say 15mm down on opposing sides.
with these cuts, you would be able to fill with weld, therefore increasing the purchase area of the weld(vertically) while maintaining the horizontal integrity of the frame tube.
just what i would do.you see honda uses a similar technique on the heavier 450 frames, and they use the heart shape on the 250.

450 design

http://i650.photobucket.com/albums/uu22 ... cb877a.jpg
fuller welds too

now you can see what im saying clearly about how i would do my cuts right?similar to the 450. like i said, im no expert, but considering these frames arent heat treated, id want my welds at least as thick as oem or do a cut out like the 450s for added strength.
do it!... cos if you dont, youll spend the rest of your life thinking about it anyway!

that looks like they ran out of rail and filled it with weld lol.

i dunno,the y section seems to be the weakest link on these frames.
i do 45 ft jumps sometimes and dont always land them right. i know that alloy frames are prone to crack and id just be shitting myself if i knew in my mind if the welds didnt look right.

its prob more of a psychological thing. the welds are prob fine. i guess youll find out :wink:
