## oops, should have read that a 2.75 inch short piece used to splice the
3 inch to the 2.5 inch.
## On my f12 40m boom, they weld every 120 degs.... where the boom drops
from
3 inch od...down to 2.5 inch OD. A short length of 2.75 inch OD is slid
over the end of the
2.5 inch tube.... then welded every 120 degs. So u end up with a stepped
reduction,
and the boom drops from 3 inch to 2.5 inch. No taper used. Then 1/4-20
SS bolts
and SS nylocks used to bolts the 3 inch and 2.5 inch booms together. Where
the bolts
pass through.... it’s a total of .375 inch thick material.
