GWA Site Visit to Pierce and Pierce



One of the activities enjoyed by my woodworking club, the Gwinnett Woodworkers Association, is to visit various businesses around Atlanta that either have woodworking shops or are in the business of producing wooden products. This past Saturday we made a site visit to Pierce and Pierce Architectural Millwork and Moulding on Buford Hwy. Ive been to this business once before to price some custom millwork (this was back in the mid 80s and the operation has expanded since then) - of course at the time I didnt get back into the operation. Seems the company was founded by a couple of guys who were having a hard time acquiring the type and style of millwork they needed to build their custom homes for a reasonable price. Like any good entrepreneurs they decided to make what they needed themselves and thus Pierce and Pierce was born.

The showroom had what you would expect - many examples of mouldings both milled and CNC-cut - there was also an assortment of corbels, decorative blocks and other elements available on shelves so you can pick up something without waiting. This company specializes in hardwood millwork, so the softest wood you would normally see here is poplar, with lots of cherry, maple and other hardwoods available. You can either select a pattern that theyve already got made-up or have them create something custom. Part of the trade is composed of matching patterns that are no longer commercially available - so if youre trying to make some interior trim thats an exact match to a
historic home, you can come to them and have them create what you need.





We walked into their main millwork area and youre confronted by lots of production equipment, with stacks of lumber to one side. The first area shown to us during this tour was their metal-working shop - this is where blade-blanks are cut into the shapes for their cutting heads, via CNC-machine. It was explained that their technicians first render the shape using CAD equipment, then the file is handed off to their cutting machine for production. Profiles they want to save can be turned into a pattern shape in hard plastic that is then inserted into a machine that follows the profile, much like one of those key-cutting machines you see at hardware stores.



 There were many examples of cutting heads - they have a six-head machine - on tables and along a long wall. He explained that the entire upstairs of the small building (it was 2 stories, built into the warehouse)  was full of knives and patterns for the heads.



There were also a row of old Foley blade sharpeners - you know I like to see stuff like this!


We went back into the production area where we walked through huge stacks of wood - most of this was surfaced, dried and ready to go. I saw tons of poplar, maple, cherry, mahogany, walnut and a few odd species like spanish cedar and sapele.


Quite a bit of the operation relies on equipment to move the stacks around. Our tour guide described the machine that rips their stock based on width and need. Much like a lumber yard, the machine draws what it thinks are the best widths to maximize yield based on the size of the board - lines are drawn with lasers and the operator can improve the yield for cutting around defects.



We were also shown their finishing area - they pretty much exclusively use lacquer. Here are a few shots of some of the equipment, including a large planer and a Stenner resaw 36 inch bandsaw.






Next we went outside where the guide showed us their two large dust collectors (cyclones) - thought you guys would get a kick out of seeing them.



We then went into their special order shop - this is where they produce those fancy doors you see with the curved tops. Lots of equipment in here so I only took pictures of those classic machines that I like so well. First up is a Crescent 16 inch joiner:


This last images is Hans standing next to a Powermatic bandsaw.


Hope you enjoyed it!

Wood Carved Jhoola Indoor India Swing Bench



Done and ready for the next one

Close Up Finished Jhoola
I just finished making & carving this unique indoor India swing bench, for a customer, it is also known as the Oonjal or Jhoola. This type of swing bench is not readily available without an overseas order. These types’ of wooden carved swings were used by Kings in their palaces and were considered a sign of royalty and are still considered even today.
This type of furniture is a wooden swing with brass chains suspending it from the ceiling of the inside of their home. I glued together three planks of solid African mahogany for a 72” x 24” x 3” think size bench. I turned the feet on the lathe and I hand carved 18 floral ornaments along the outer edge. It took me about 4 ½ hours for each individual carving.

Tough Going with Follow Me


The Follow Me Tool has been one of the most reliable and effective tools in my design of furniture in SketchUp. After all, I like furniture with turnings and moldings so Follow Me has been frequently used with successful results. So I was surprised recently to run into some difficulty with the tool.
I ran into the problem while working on this Philadelphia Lowboy. The Top has a molded edge, but note the unique curved corners in the front.
Here is a close-up view of the front corner of the Top. I wasnt expecting any difficulty making this shaped edge, so it was quite a shock to see funny results with Follow Me. This set me back several hours as I began to experiment with alternative ways of using Follow Me. I knew that it could be done with a plug-in, but I was stuck on making Follow Me work.

The following are some of the steps I used to finally achieve an acceptable result.
Step 1: Here is a plan view of the Table Top corner along with the profile shape. Using the Arc Tool, I drew over the top of the shape shown with red edges and blue face. The angle at the corner is of course 45 degrees, so I placed an angled guideline with the Protractor.

Step 2: Expecting some difficulty with small facets, I scaled up the size of the corner shapes by a factor of 10. Then I placed the profile shape onto the flat shape as shown below. I selected the Follow Me Tool, clicked on the profile shape, and began to drag my mouse along the front edge.

Step 3: Here I am dragging the mouse along the front edge and watching the profile shape extrude the molding step-by-step. Of course, you can operate the Follow Me Tool differently by selecting the path, then clicking on the profile shape. But in this method, it is more difficult to see how Follow Me works and how the profile moves with respect to the path. Note that the profile always positions itself perpendicular to the path.

Step 4: Here Ive completed the Follow Me along the entire front edge across the corner. And you can readily see the problems at the corner. This is caused by the path turning in at the corner so that the profile rotates back on itself.


Step 5: Next I restarted the Follow Me, but this time I used the back edge as the path.

Step 6: Even though there were again problems at the corner, I could see a smooth and proper curved face through the corner. The extra edges were a result of face geometry created within the envelop of the molding shape. So I set out to edit and clean-up this area of the corner.

Step 7: I created a cutting plane at the 45 degree angle. Then I selected all geometry and executed Intersect Selected. After cleaning up with the Eraser, here are the results.

Step 8: Using the Push/Pull Tool, I extended the straight portions of the molded edge.

Step 9: I created one-half of the Top by closing in the top and bottom faces. Then I copied and flipped this half to make the whole Top piece.

I suspect there are easier ways to accomplish this difficult shaping (with Plug-ins), but now I know it can acceptably be done using Follow Me only.
