Using Foam Core to Construct a Room Box, Part III:
Questions and Answers

George Hoffman


Jim has the following questions.

Question #1:
The ceiling doesn't appear to have pine strapping, yet the side and back studding rise about 1" above the ceilings. Is this airspace, and if so how far can Foam Core cover with out support?

Answer: (See Part III drawing below.)


Question #2:

Does plywood finished exterior screw into the ends of the pine studs? This seems like the weakest place to put a screw!

Answer:


Question #3:
I think I understand the side and back exterior finish plywood glued to the studs and gator board base, but what if wiring pulls loose. How would you get to the wires feeding down through the sides and to the switch hub box?

Answer:


Question #4:
Does the bottom of the finished plywood sides glue or screw into the 1/4" Gator Board (or 1/4" plywood) base --- what would it screw into?

Answer:

 

 

Question of the Week: Answered by Jack Blackham

Question:

This forum is a great idea! Could you please explain the difference between a jig and a fixture?

- Thanks, Beth G.


Answer:

Dear Beth:

In response to your question about the difference between a jig and a fixture--they are essentially the same. A fixture is usually temporary and a fixture is permanent. For example you might make a jig out of wood if you only wanted to use it 6 times, but if you needed it 100 times, well then you`d make it out of metal and it would be called a fixture. Hope this answers your question.
