4. GENERAL ASSEMBLY OF HALF ELEMENT SECTIONS
We recommend assembling the half element sections on a
clean, flat surface. There is an “DIMENSION/ ASSEMBLY”
drawing for each of the four elements with both the right
and left halves shown on each page. We also recommend
briefing yourself with the general directions before
skipping to the assembly drawings.
The general assembly procedure for a half element section
begins with laying each capacitor assembly on a level surface,
with the 10m capacitor tube on the left hand side. Locate the
two swaged 3/4” diameter tubes and the 5/8 x 6” fiberglass
rod.
NOTE: BE SURE TO USE THE CORRECT LENGTH 3/4”
SECTIONS MATCHING UP WITH THE 10M CAPACITOR
LENGTH.
Insert the fiberglass rod into the LIGHTLY
swaged end side of the longer 3/4” section. Align the two
holes and secure loosely with a single 8-32 x 1” screw and lock
nut in the
outer hole
as shown in Figure 4. Next slide the
other end of the fiberglass rod into the center hole of the 10M shorting bar connected to the 10m capacitor. Now
slide the lightly swaged end of the shorter 3/4” x 12” tubing through the hole of the shorting bar connected to the
15m capacitor tube. Secure with a single 8-32 x 1” screw and locknut, again through the “OUTER HOLE” in the
figure. Now insert the inner two 8-32 x 1” screws and locknuts, and tighten LIGHTLY. NOTE: IF YOU OVER
TIGHTEN, YOU MAY NOT BE ABLE TO MOVE THE SHORTING BARS TO THE FINAL POSITION. Slide the
two shorting bars right up against the two inner locknuts as shown. Now tighten all four inner and outer screws
and locknuts. Position the capacitor tube assembly so that the gap rests in between the two shorting bars and
MAKE SURE THE MARKS YOU MADE ON THE 3/8” TUBE ARE
UP
. Tighten all of the 8-32 hardware installed
to this point.
Locate the appropriate 1/2’ element tip section and insert the end with two holes into the 3/4 x 12” swaged end.
Secure the 1/2” tip with two 8-32 x 1” screws and locknuts. With a tape measure hooked to the inner edge of the
15m capacitor tube shorting bar, make a mark on the 3/8” tube at the dimension called out for the 15m shorting
bar. Slide the 15m shorting bar onto the 3/8 and 1/2“ tube and set the inner edge if the bar to the mark. Install
two 8-32 x 1” screws, add locknuts, align with the other two bars, and tighten.
Locate the 10m shorting bar and the shorter 3/8” tube. Using a tape measure connected to the inner edge of the
10m capacitor tube shorting bar, mark the dimension called out for the 10m shorting bar. Slide on the 10m
shorting bar, set the inner edge to the mark and tighten the top 8-32 screw. Now insert the shorter 3/8” tube
through the other hole on the 10m shorting bar and into the free hole on the 10m capacitor tube shorting bar.
Allow the tube to extend 1” past the shorting bar connected to the 10m capacitor and tighten the 8-32 hardware
on both of the shorting bars.
Using the general directions above and the four TIP DIMENSION assembly drawings, proceed in fabricating the
8 half element sections. After double checking your dimensions and making sure that your elements are labeled
correctly proceed to the next step.
