 3. Temporarily mount the canister mounts and install
canisters to center the mount. Use lubricant on the canisters
for easier passage through the mounts before they are glued.
The canister mount touches the floor of the fuse and needs
to be glued to the sides and bottom former. Once mount is
centered, mark the spot on the sides and formers. Remove
the canisters and apply glue to the sides of the mount and
fuselage where they contact using 30-minute epoxy to
enough have time for adjustment.
Canister/Header Assembly
 1. Recommended header length for MTW TD110 canister
and DA-170 is 8--9-inches. Cut 1 inch off the stock header.
Assemble the canister/header using a vice-grip to open the
clamps and slide them over the header first then insert the
header and canister into coupler. Leave 1/8--1/4 inch gap
between header and pipe. Since the bump on the header has
to be cut for optimum performance, tap a button head 4-40
screw on the header and slide the slot of the clamp over the
button head screw and coupler to avoid slippage.
