|I had already designed a velocity stack for my panhead a while
ago, intending to do it in sandcasting. I started by doing a print
to check all the dimensions, and all looked good. Just out of
curiosity, and because I realised the walls were quite thin for
casting and might give problems, I inquired for 5-axis CNC machining
but keeping the shape exactly as if it were a casting with draft
angles and all. Price turned out to be reasonable so I had 10
of them machined in 6061 aluminum.
The results were really very nice and it turns out they
fit on the Panhead's Linkert carb and also on the Linkert I
have on a 45"WLA flathead motor here. Next challenge would
be to make a removeable mesh, as the screws had to remain reachable.
I machined a little tool to mount the velocity stacks in the
lathe to machine the groove. There will be a stainless "clip"
holding the stainless mesh in place. Currently I am experimenting
with making a domed mesh, as this will increase the strength
as well as the surface area, to be continued.... By the way
if you want one without the mesh I already have a few extra
