That's a neat tool. A header guy shared with me to "...squeeze the round tube in the vice to the width desired, then "whang" the top with a hammer, squaring it off. Flip it over and "whang" it again to square off the other side. then selectively massage it to fit. I like your tapered tool better. It looks to be only nominal 1/8" (3mm) flat stock welded?Quote:

Your absolutely right. I had to make a 1/4" plate anvil the width of the tube ID, with rounded corners, that I clamped into the vice. On my header flanges the perimeter of the port is equal to the OD circumference of the 1.75" primary tubes, so that when formed the tubes slide into the flange. Not sure if yours are that way or not. With the SBF ports being taller than they are wide the tool you made would be a bit more "interesting" to form.Quote:

takes some grinding to get the shape right, but with the sizes available to start with, it works pretty good-and they have a 3/4 inch handle to hammer on--
The smithys used to say: "If you hammer cold steel, the devil will get you"
Just old trivia.
This little tool was originally made for SBF headers, just use the first few inches of it.Quote:

Anyway I did find something to make I needed to spin some blank off plates for the ends of the collectors, only had 1/4" stainless plate so marked out the round end caps and plasma cut them to rough shape and finished in the lathe. Also made some gaskets.

I had intended to just use nuts to hold the caps in place but as I had a little time spare I decided to make some stainless tri bar wing nuts instead, gave them a quick polish. I couldn't be bothered to polish out the welds, may do it later.

Steve, if the tool is square how did you deal with the rectangular ports on SBF headers? Wingnuts look killer, BTW!Quote:

Well 2 dry days in a row is pretty amazing at the moment !!! Still waiting for exhaust bends to arrive from Italy but I did trial fit a header to get an idea of the look, nothing super tricky but I absolutely love the way they look

Also I was in need of a fuel pump blank off plate so milled one up from some aluminium plate, also gave it a little polish.

Another job I wanted to get done was to mount the Vega steering box, no mount available to buy so made one in 3/8" plate steel, Also knocked up the draglink in 1" CDS tube. I need to make a new pitman arm with a crank in it, will do that over the next few days.
