Example: Bending Tube Clamps (continued)
Double-Tube Clamp
To make a 1-in.
1.0.
tube clamp (for clamping two lengths of I-in.
0.0.
tub
ing), using a 6'lz-in. length of 'I..-in. x I-in. hot-rolled flat stock:
NOTE:
To make other sizes of clamps, experiment to find the appropri
ate die sizes and stop block orientation.
1.
With a long hinge pin, attach the handle and ring loops at their center
pin holes. Install a 1-in. die on the center pin.
With the short hinge pin, install a
1
'Iz-in. die in the handle
(#2
hole).
2.
With a long hinge pin, install the stop block (oriented as in
A).
3.
Insert the flat stock into the Bender so that
it
ex1ends 13/,-in. beyond the
center-pin die (as in
8).
4.
Make the first bend by pulling the handle around until the handle die
runs off the end of the piece.
5.
Reverse the part end-for-end. Insert
it
into the Bender
SO
that it ex1ends
13/,-in. beyond the center-pin die (as in
C).
6. Make the second bend by pulling the handle around until the handle die
.
runs off the end of the piece.
7.
Remove the stop block, and install the sharp-angle-bend attachment.
8.
You will have to temporarily remove the center pin to insert the piece
into the Bender. Slide the piece as far left as possible, against the cen
ter pin (as in
D).
Insert the fixed stop into the 6th hole of the ring (counting clockwise from
the closed end of the loop).
9.
Make the third bend by pulling the handle until it is about 'I, in. from the
stop pin.
10. Reverse the part end-for-end.
Slide the piece as far teft as possible,
against the center pin (as in
E).
You will again have to temporarily re
move the center pin to insert the piece into the Bender.
11.
Makethe fourth bend by pulling the handle until it is aboui 'Is in. from the
fixed stop.
