Iron Horse Sunday Reborn - A Classic Downhill Bike Modified with Modern Geometry & Mullet Wheels
@westagil: Being in the industry making and testing frames of all sorts i strongly advise you to find someone that can heat treat 6 series material and do some sort of basic testing. I guess all tubes are a mix of 6061-6069 so that will work. Look at Iso 4210 or consult Zedler. Without destructing it, you can load it up to a threshold deemed as the minimum acceptable. If it does fail at such low load, well... better it's in the lab than on the trail. That Head tube in particular is sketchy. You have increased the angle, removed the reinforcement gusset and not heat treated it.
Good job on the welding fixtures though. that's cheap and functional!
