As above.

if you know how they are made (homemade) please share!

Thanks!

I am talking about something like this

 

i would not consider those to be velocity stacks... they are just short transitions. i make those on my arbor press with a cone shaped die.

these are closer to velocity stacks:

 

^^ please tell how those look awesome

 

more than likely a triple-die process to make what Weir posted...make your first press, which will probably look something like what the OP posted, then another to push them further out to horizontal, then one more to round it off and push it straight down

 

the ones i posted were cnc machined from 3" round solid billet.

 

Hi Weir.

Could please tell hiw is it done? (With some pictures to be more clear ....if it is posible.)

Thanks in advance!

I bought some several years ago from Velocity of Sound, they are spun aluminum. This gives them the nice tapered shape. Probably not something your going to be making at home.

Another more of a one-off way to do the sheet metal stuff is hammer forming. There are probably a half dozen ways to do what's pictured above.

You could start with the tube and bend a round piece of rod so it fits around the outside of the tube. Then weld on some legs for the ring of rod. And last hammer the edges of the tube over the rod circle.

 

spinning has always been very interesting to me for some reason. I can watch that all day. haha
