« Part 1: Starting with the top. Part 2 of Pie Crust Table series Part 3: More work on the top. (Does it ever end?) »

In this installment I will machine the outside edge

The first thing I do is break out my large circle cutting jig. It’s set to give me a 34” circle. Then I drilled a 1/4” hole 3/8” deep into the center of the top to use as a pivot point using a 1/4” dowel. (Don’t go any deeper. This will be machined out later to remove all traces of it.)

After that is done I mark up the top into 8 pie sections and carry the line over the edge a little ways.
.

.
While it’s set up I make a blank template from the corner from a piece 1/4 MDF. I just flipped the jig upside down and fed the part. Make sure that you feed it against the rotation of the bit!
.

.
Then I assemble my Paper patterns. You can download it HERE in pdf format.
.

.
I then marked 3 lines on the MDF matching those I previously drew on the top, again carrying the line over the edge, and then drill a 1/4” hole where they meet.

Then carefully cut out your pattern as shown in the next picture.
Then I lined up the pattern to the edge of the top and the lines drawn as shown. Then tape it down and trace the pattern to your MDF. Then you need to carefully cut out and sand your template. This will give you a template that will allow you to route 1/8th of the top at a time.

The reason I only put the pattern on half of the MDF template is that it allows you to clamp the other half to your top out of the way of your router.
.

.
Here is the bit I used for my first pass. That’s a Porter Cable trim router.
.


.
Then just line up your lines and add a clamp and you’re ready to route.
.


Here it shows the cut


.
Here is the first pass complete.
.

.
1/8 of a section complete.
.

.
.
Here I want to add a few comments about routing it. Be very careful of chipout on the sharp points. It turns out that small diameter bit work best. Pay special attention to the grain direction.

I used a 3/4” bit and had some chip out. This required that I reduce the diameter of the top to 33 3/4”. I just used the same template and moved it in 1/8” from the edge and routed it again. Oh, well. Live and learn.

.
.
Here’s quick video of that broom I reviewed. You can see just how nice it is to use and how well it works.

Gary. The table top looks great. I wonder about using a carbide spiral bit. You can get them with bearings also.

Gary,

I see taking care of your daughter has given you a new skill, you can sweep with one hand and do something else with the other (hold the baby or a camera) ;^)

Thanks for the tutorial. Did you have any problems as you changed the depth of cut on the trim router? Mine always seems to be “off” a little with each adjustment. I wasn’t using a bit with a bearing, however.

Nice start. Did you get your pattern some where or draw it yourself?

For those who want to supplement Gary’s blog, years ago I came upon a book that is dedicated to making a piecrust table. Making A Piecrust Table by Tom Heller and Ron Clarkson, Schiffer Publishing 1994. Nice job Gary. You appear to be well organized. Keep updating the blog.

These tutorials are certainly valuable, and I’m wondering if I am looking at galley proofs for a new book!

Hi Gary
Nice tutorial – Thanks for the tip on the bit size . I guess I need to get some new bits soon. By the way I cannot download the video on the action of the broom.

Karson – I don’t have any, so I just used what I had laying around.

Lew – They were off a little, but this isn’t the completed edge anyway.

TopamaxSurvivor – I just took the pattern from the picture in Part #1. Don’t know exactly how close it is though.

rtb – You can find one at any Asian store.

Tony – Don’t know why you can’t see it. Try this: http://blip.tv/file/2061901

This may be a dumb question, but I noticed that you say “carefully” cut out the pattern. Did you use any tircks to make the smooth curves? I assume it was done on the bandsaw. Maybe it takes practice, but I’m not very good at folloring a line perfectly.

My guess is that the better the pattern, the better the table. Just wondering.

Hokie – I use whatever method will best do the job. In this case I used a bandsaw to cut close to the line and then a spindle sander to take it to the line. I will also use files and small sticks with sandpaper glued to them for tight areas.

I some cases the pattern doesn’t have to be perfect, just consistent.
