It's birthday time for the kids so I thought I'd make
them something: that means project time again! We have four kids with all their birthdays
only three weeks
apart, and three of them are within five days of each other. How's that for timing?
Two of the kids, Stef and Tracey, are big football fans
so I thought I'd make them something football related. What I had in
mind was a serving tray that would hold chips and dip, and
they could use it when they watched a game. Or anytime for that matter.
The material for this project will be mahogany and
maple. The reason for these two species will be evident very soon. The
size of the mahogany below is 23 X 13 X 1 3/4 thick so lets check
out how the project was made.
|
|
I cut some maple into strips that were 13
X 1 3/4 X 3/4 thick. I'll be using two pieces per serving tray.
|
|
I cut each surface to make sure they were square so I'd have a nice edge
to work with.
|
|
I cut the mahogany with my circular saw and then machined those cut edges
square like I did with the maple.
|
|
Here are all the pieces glued-up which I let set overnight.
|
|
The next day I used my milling machine to surface both sides. Notice the
area at the top-right that didn't clean up. That won't be a problem and
you'll see why later.
|
|
The pencil lines mark the center of the project which I'll use on my next
setup. Again note the area at the top that didn't clean up. This area won't
be a problem either.

Over the July 4th. weekend, I went into my work and used the CNC milling
machine to cut the shape that I was after.
|
|
Here you can see one of three pockets that will be cut.
|
|
This should give you a better idea of what I'm making.
All of the pockets are finished here and I've cut around the perimeter
with a 3/8" end mill, but not all the way through. The reason I didn't
cut all the way through is because an end mill can be somewhat
unpredictable once they break through. When they break through they can
bounce your part around which may put some unwanted cutter marks where
you don't want them. Or even worse, leave your wooden part destroyed. I wanted
to make sure that didn't happen so I stayed away 1/8" from going all the
way through.
You can also see the football shape that I'm making
here. Now both girls are into pro football but I wanted the look of one with stripes, like a college ball has. It gives it a nice
contrast but still gets the point across that is it's football related.
|
|
Here you can see a 3/16 radius that goes all the way around the top
surfaces (inside and outside). If you look close you can also see the
same size radius at the bottom of the pocket.
|
|
I used a bandsaw to separate the pieces and I kept the blade in the middle
of the 3/8" slot, which worked like a guide for me.
|
|
Here you can see how it looks with one half cut away. This worked out
great and went really fast.
|
|
The small marks at the top of the cut-away piece are where I had the
3/8" cutter enter and exit. Now it's time to do some sanding...a bunch
of sanding!!
