Quick video of the process I use to make a tail. This one is steel and came out fine. 1.5 hours time so far. I'll finish it Wednesday

Sandbag and mallet to quickly stretch the center. Pullmax on the edges that need to be shrunk. Then planishing hammer and party.

Holy crap, that was quick.  The planishing hammer seems to make short work of it.

CB550 to match my car....

To be honest the planishing hammer doesn't do much other than smooth the metal after. Most of the shape was done in my Pullmax hammer which was the first one. I have special dies that grab the metal and force it into itself, shrinking it's surface area. They leave some marks and the planishing hammer takes those out. I also ran it through my English wheel in the end to wash over any highs and lows. It's 75% there I can still metalfinish it more. And I will after I build the rest.


Whatever I know about sheetmetal and fab I lack in wiring and mechanics. I have no idea how to make this bike run or wire it but I figure this is the place to be haha

I think I got my tools mixed up.  I was referring to that nasty bastard with the dies. 

Very impressive!

Thanks. Had some stuff to throw in the powder oven tonight so this went in and got a fresh coat of matte black. Gotta straighten out the Honda tag. Unless somebody knows where I can source a new one.

My home made oven. Should fit the frame.

Yamiya sells those.  Look at the Frame Group -- Handle Top Bridge.  They go for $10.19

Decided to try to build an aluminum tank. Going good so far. We'll see how it pressure tests eventually. It might be a trash ornament in the end but it was a good experience. Had to anneal the metal a few times to shape it, also made me a new English wheel that actually works unlike my old HF one





Rough shape


Made the other side

Start connecting the two

Killer looking tank! I bet the English wheel comes in handy from time to time.

Never seen anybody build their own english wheel before. Without the metal working stuff it looks like a piece of modern sculpture.

Thanks so much for the kind words. The English wheel is a powerful tool but I start most everything on a stump or sandbag. I smooth and do the final 10% stretch on a wheel.  A stiff frame really makes a good wheel, which is why I had to get rid of the HF one. Also proper anvil alignment is key. I like the finish it leaves. Made this one the other day while my lady was snoozing.





The jade tank is staying until i pressure test and like the new one.
