3 - Yamaha Marching Toms and Randall May Free Floating Lug Bridge Assembly Instructions
Attach the 6" or 8" space spock drum.
nYour extra 6" or 8" or both will have a pre-installed
metal bridge (image C). These bridges take the
place of the regular Yamaha lug casing.
nAttach the metal bridge to the corresponding shell
as shown in your configuration diagram.
nLocate the bag of bolts, washers and nuts with
sprocket (image D).
nPlace your 6" or 8" or both on a flat surface within
your drum array configuration so you can connect
them to the correct corresponding shell.
• Insert the bolts through the holes in the shell.
• Slide the channel of the bridge down the bolt head.
• Fasten the nut on the inside of the shell (image D).
NOTE: The height of the bridge is important. Image D
shows the top half of the bolt head. This is the ideal
height for the bridge on both shells.

Attach the back rail to the outer drums.
nLocate the bag of bolts, washers and nuts without
the sprocket.
nInsert bolts into the opening channels on both
sides of back rail (images E and F).
• The bolt head should face out of the channel.
• Place the washer on the bolt and loosely tighten
the nut.
nRepeat on the other side (try to insert both sides
of the rail simultaneously so that it’s even).
nOnce the rail is in place, tighten using the 7⁄16" wrench.
Assembly before back rail. Assembly with back rail. Images show drums
without heads, hoops and tension rods.
