PORT PLUG MACHINING OPTION
Port plugs can be purchased with or without a bore. If purchased without a bore, the
following steps may help you with machining them to fit your needs:
1.
Plugs will be sent whole and cut to specified holes, solid plugs with have a ¼”
hole for custom drilling. Make sure you use a wood backing to drill into as this will
prevent breakage of the plug. For smaller holes, use a regular drill bit. It may dull
faster if you are drilling multiple holes. For large holes, purchase a hole saw with
the correct size for your requirements.
2.
With the correct size hole saw, place the port plug in a drill press or drill. Drill into
the plug keeping a vacuum sweeper handy to collect the dust and pieces. A
normal hole saw does not have the depth required for a 2" thick piece.
It
may
require you to flip the piece over and continue drilling. Discard center pieces and
check for fit.
INTERNAL OVEN CHAMBER LIGHT (OPTIONAL)
The current light cannot be operated above 600 Deg. F (315 Deg. C).
If
you are
planning to conduct testing above 600 Deg. F, you must remove the light bulb and
replace it with the insulation plug provided. If your oven was not rated for operation
above 600 Deg. F, then no insulation plug was provided. Operation above 600 Deg. F
with the light bulb in place will cause early failure of the bulb and perhaps cause the bulb
to explode.
SLIDE ASSEMBLY MOUNTING BRACKETS OPTION
This option allows the oven to slide backwards out of the test frame. This exposes the
oven's working area for ambient testing when needed. The locking pins on the side hold
the oven in the forward position.
