Shweeet, will c you'll there

Fancy makin it sunday mr K? Mite be a lil oxford meet on saturday tis all. Ta, Josh.

Paint's a winner here

? Even the hosing's frozen!

Ahhh, TIG Parweld xti201 i think it is . Higher in silicon, but also magnesium. Think it has a higher overall yield strength. Beautiful, thats one thing that i had no idea about on this one thanks for that . Cheers, Josh. Edit- i tell lies, lower in silicon, dosent flow as easily as 4043 I think that the welds on this also aren't going to like the anodising, but we'll see what happens with that.

nah, not saying you were like, you sound like a well educated fella. What do you mean by rig? If you mean jig, just the one that i've made up like, pics are up at the start of the first post. Material is 6082, mainly because it was easy to get hold of and a little bit cheaper than 6061, is also a little stronger once hardened. Using 4043 rods, but think i'll move to 5356 in the future. Not sure yet, im going to get in touch with a couple of heat treatment places that are in the area and see what they think would be best, but from the research that i've done, i think it'll be solution then artificial aging. Cheers, Josh.

Ritey o, fair do's. I still dont really see a problem with it, my baby pitbull's gussets are welded all the way round and that is probably one of the strongest frames around (seeing as it has lasted nearly 7 years and has been through a long line of riders). I have just seen so many frames crack/snap at this point after a good smack to the downtube, don't really want this to happen to mine . Dont wana argue about it really, it'll be different on the next frames . Cheers, Josh.

Grease it if you've got grease to hand, but if not, dont bother. Havent greased any of my freewheels whilst ive been riding and have never had any problems with either maintaining the freewheel/cranks or removal of the freewheel. Cheers, Josh.

Cheers matey, im pretty happy with it atm. Yh, bits nd bobs, mainly to do with the angles that the tubes were bent to and the gusseting really. This one took alot longer, but has gone so much smoother than the last, having a decent jig to assemble it in helps so much, lol. Cheers, Josh.

Well, we were gona head to hathersage, but opted out, and heading to reading/bristol on sunday, so keeping it local before a long drive .

How do all, heading to Leicester tomorrow, wondered if anyone else wanted to join? Will be at the courts around 11ish as usual . Cheers, Josh.

Ritey o, fair do's with the oxford, mighty things . Cant really help you on choice, only ever used parweld and lorch, wich are both pretty much the same, apart from the lorch comes up with error codes every 2-3 weeks . But most of our stuff is parweld and never have any problems with them . Cheers matey, Josh. Oh, update in 2 seconds nd all.

Pulse transfer, it raises and lowers the voltage very quickly like, which sort of imitates AC characteristics when welding. I wouldnt go near MIG for welding up any frame, wether it be ally or steel, stick with TIG . Cheers, Josh. However, they are very usefull for when your tacking it all up .

Yh, the chainstay bit is my favorite bit of the frame. Iv'e welded the gussets fully because i've seen alot of frames crack where the weld normally ends. It seems that it only takes a small defect in the weld at this point (normally whats called a 'crater crack') to make it crack quite easily. Im not exactly practiced in the whole stress analysis thing, but to me, leaving the gusset open would only put more stress on the weld at the two points where it ends? Not too sure about it if im honest, going on my own experiences, sort of experimenting, will probably leave the gussets open on the next one, see if there's any difference when they're both ride-able. Cheers, Josh.

Precipitation section you want matey

Would also like to know this, always seen open ended as a bit of a weak point? Josh.
