The first step is to cut the PVC connectors that will
connect the PVC fittings. To determine the connector
length, measure the distance from the inside stop of the
fitting to the end of the fitting. Multiply by two and
subtract 0.1 inches. For the fittings that I used this is
1.5 inches. I used a band saw with a stop at 1.5 inches to
get the correct length.
Once they are cut, check for squareness.
If not square, use a disc sander to square the ends. Use
the disc sander and put a slight taper on each end. A
total of 22 connectors is required for the project.
Next the vertical hold pieces are cut. Lengths are marked
on a piece of PVC and each cut. These are stacked
vertically and lengths compared and adjusted using the
disc sander. Using a belt sander, a slight taper is put on
each end.
Next cut eight pieces 11.5 inches long. Check them to make
sure they are identical lengths and taper the ends. Here
are all the pieces cut and ready to assemble.
The above process take about four hours.
With all the pieces cut, it is time to do dry fits. The
PVC tees are joined together using the couplers. The
couplers are a tight fit and all must be aligned straight.
Dry fit the entire assembly to make sure the couplers are
correct. I found that some of the couplers needed to be
thinned down. I did this by rotating them on the belt
sander. Once everything is checked, insert and glue
couplers in place. Because you have limited time to adjust
pieces before the PVC cement sets, the couplers are glued
into the PVC tees. You will notice that some have two
couplers and others just one. The next step is to join two
tees together. Glue is put in one tee and the other tee
with the coupler pushed into it and the two tees forced
flat onto a flat surface. This is done to make sure that
when all couplers are joined together that they are
straight. At this point you will have four sets of two
tees. Next you will glue two tees to a group of two tees.
This completes one side piece. Repeat and make the second
side. Check to make sure the two side pieces are equal.
Take one of the 11.5 inch pieces and glue a tee to it.
Repeat with another 11.5 inch piece of PVC. Once the glue
is dry, take one piece and glue a tee to the other
end. Press the tees against a flat surface to insure
squareness. Once dry insert a coupler into the one end of
each tee. Now take the piece with the horizontal piece and
tee and attach it to the connector on the completed
horizontal piece. Take a tee and place it on the other end
of the second horizontal piece and then onto the coupler.
If everything is correct you will have two identical
pieces. Now remove the unglued piece and apply glue and
re-assemble.
It is time to assemble the unit. You will need a flat
surface and straight edges. I used a heavy metal ruler for
one side. Insert photo 0071 I then used framing squares
for the two sides. Insert photo 0072& Insert
photo 0073 The photos show the dry fit assembly.
Now disassemble and carefully glue and reassemble.
The vertical dividers are now put in place. Any
misalignment will be obvious. Adjust them to bring into
alignment. I used a piece of straight wood to align them.
Once they are aligned they can be glued. You may notice a
vertical piece with a 90 degree fitting. This is a piece
of the handle that is dry fit to help with the alignment.
The next step is to assemble the handle assembly. Dry fit
and make sure the two assemblies are identical. Once
identical then glue the assembly making sure that it is
square.
One final step is to add sheet metal screws to the ninety
degree fittings.
This is insurance that if the glue joint fails that the
assembly will remain in place.
