Re: Need opinions on problem. Had a manifold crack but really strange.
i'd like to see pics of the edges of all the flanges to make sure it wasn't dropped. i'd also like to know what type of filler material was used for the welds. 2 possibilities?

It was 308L rod. When I made that I was welding at a very high amp. Around 165. From practice and experience I have since lowered amperage considerably. It is all a learning process. Through all my manifold sales I have always been up front to tell people I am a HOBBY welder. I am not a welder by trade. Keep in mind that Aaron paid $175 SHIPPED for this. I was not out to make lots of money. It was more hobby and some money to help out with bills. Do the math. After materials, filler rod, argon, electricity, and many hours, how much money did I make? My new stuff is light years ahead of my first stuff and the prices are about the same. I only make 1 to 2 manifolds a month now. I started a little website but realized I don't care to make a job out of it and will be closing the site at the end of the month. Like I stated earlier I will make a new one free of charge for Aaron and he has requested changes in design and an exteranl wastegate that I do at no charge to him. I made this post not trying to hide mistake but to honestly find out problems in my process and or design.

Re: Need opinions on problem. Had a manifold crack but really strange.
okay after those second sets of photo's it looks like you made more than 1 pass and or ran filled a larg gap? but those craks did start at the edge of the bead and move forward. YOu were right to think it was the heat you welded at. The metal got too hot and became fragile and craked. Like you said you do this a s a hobby and you have improved 50x scince that time so build the new one and move one. Bottom line is your manifolds work good and cost less than the pros and you are doing a free replacement. The fact your making changes for free is a big testement to your busns morals.
