PA Farm Show

Agriculture is the #1 industry in Pennsylvania. And the largest indoor Ag event in the U.S. —the Pennsylvania Farm Show—has been housed at the PA Farm Show Complex for the last 90 years.

Some main attractions include a life-size butter sculpture and farm equipment displays; competitive events such as livestock judging, cow milking, equine showcase, carriage racing, and sheep-to-shawl; and food contests like Blue Ribbon Apple Pie and Greatest Cocoa Cake.

There are also rows and rows of farm animals. Alpacas are my mom's favorite (photo #2). To get a sense of the size of the Alpaca named Samson, my mom measures 13.2 hands at the shoulder.

The food court offers local goodies like fresh squeezed milkshakes, funnel cakes, mushrooms, and maple syrup desserts. Not a good place for dieters, only 5 of which reside in Pennsylvania.

This year, and the sole reason I went to the show (besides the chickens), was a display of a 1/12 scale model of one of the most recognized barns in North America--the Star Barn, c.1872. The star motif represents hope and good fortune for the farm and land.

The model builder, Terry Spahr, spent 11 months constructing the exact replica which includes 15,000 roof shingles, real stone, and miniature metal hinges; and the hog & chicken barns and corn crib outbuildings.

As luck would have it I was able to talk with Terry, who explained that most of the wood he uses is douglas fir and balsa, and that 2-part cyanoacrylate glue holds the pieces together. He uses 10" and 6" table saws with Piranha saw blades, a band saw, and dremel tool in his shop (among other tools) and builds by the addage "If it's something worth doing, it's worth overdoing it."

I can believe it, having seen his work in person.

Fully replicated interiors include staircases, stalls, feed bins and if you look closely in the last photo, you will see that the support beams are chamfered.
Even if chickens with puffy tresses and bunnies the size of tractors (there's always lots of big hare at PA farm events) aren't your thing, the Star Barn replica makes it well worth the smell of admission.

Dare to Move Your Light

Unless you're planning to spend all your time standing beside your finished piece with a task light shining at an optimum angle, it's a good idea to inspect it with light shone at various angles while it's still under construction.

This is especially true in carving, such as cabriole legs, lettercarving, shells, and anything in which you have to shape a piece with handtools. All will benefit from this kind of scrutiny.

I'll forewarn you...this is not an exercise for the faint of heart. Just when you think your fine skill has generated perfection, a readjusted light will make mockery of your workpiece and reveal with glaring clarity just how imperfect a creation you've painstakingly crafted.

However, it does give you the opportunity to make corrections and ensure that your work will look its best under any kind of light.

Even the type under which it will eventually most likely be found — boring, indistinct, overhead light. (See last photo....ew.)

Drawer Front














The drawer front on the sawbuck table has a raised decorative shape. A template from paper was used to trace the outline onto the wood. Then I incised the outline with an exacto knife, used a chisel to define the line, and used gouges, chisel, and shoulder plane to remove the waste.

A little touch up with sandpaper and it's ready for the date to be inscribed.






There are a few dings and mistakes, but that's one of the things I like about PA German furniture: it's okay to see tool marks and imprecision. That's what gives it its warm appeal.

Creating A Cove

The original sawbuck table (pictured at right) has a raised panel on the drawer front, comprised of sloped edges that rise up to a decoratively-shaped field where the date and drawer pull are found.

All of the raised panels I've ever made have had flat slopes, but the sawbuck's are concave (cove profile).

If you don't have a moulding plane that matches the cove's shape (raising hand) and believe it's too dangerous a task to be performed on a table saw (raising both hands), then you need to get resourceful.

It's all about stock removal. How you achieve it depends on the tools you have and your personal preference.

The top edge of the slopes sits a bit lower than the decorative field, so I reached for a tool I'd never used before, a Record 043, to define the depth of the recess and the width of the slopes.

Even though I spent time sharpening the Record's blade and flattening the fence and depth stop, it worked very poorly—tearing up the wood like kids unwrapping Christmas gifts. It was difficult to keep the fence tight against the edge, due I think to the type of wood—curly cherry.

So I employed my Sargent combination plane, which worked superbly.

From there, a block plane, moulding plane, rasp, scraper, and sanding block finished the profile. Some of these steps could have been skipped, but I was figuring this out as I went along.

I'm sure there are a number of other ways to create a cove so feel free to share your own creative methods.

Caution: Woodworking Links Ahead

I recently came across a woodworking site where the owner, Jim Boyett, has compiled a heaping helping of links to sites about hand tools.

Careful, though. I recommend only visiting the site when you have lots of free time at your disposal.

Half Blind Dovetails

I believe the two most important skills in handcutting dovetails are careful layout and the ability to saw a straight line.

Regarding the feather-ruffling question: Pins or Tails?

My answer is: Yes.

For a box or drawer that will have fat pins, I cut tails first. Cutting the tails first allows you to saw the two tail boards at one time. Plus, transferring layout lines from tails to pins is easier than vice versa.

For a delicate project with skinny, English-style dovetails, I cut pins first. With thin pins, it's very difficult (and in some cases, impossible) to transfer layout lines from tails to pins, so cutting pins first makes sense.

That being said, I'm cutting tails first for the drawer on the sawbuck table, with through dovetails at the back and half blind at the front.

The drawer will have angled sides, so the width at the top is 15" and the width at the bottom is 13". I believe I've mentioned my geometry-challenged brain before.*

My tool arsenal includes: dovetail saw, jeweler's saw, various chisels, guide block, plane blade, pencil, ruler, dovetail marker, clamps, marking gauge, mallet, and tiny square.

I call the technique: Dovetails with Training Wheels.

The training wheels are in the form of a guide block that's used to keep the chisel perpendicular to the workpiece. This ensures that the area that's removed between tails & pins will be flat. Some people like to undercut this area so pins and tails seat exactly to the guide lines, but a guide block removes this potential problem.

Once I've cut the tails, I use a bevel-edged pencil to transfer the outlines to the adjoining board, but you can also use a marking knife. Take care to make precise marks when you transfer these lines. When you saw the waste, cut right to the line (the line will just barely be sawn away when you've finished cutting). The more accurate the layout and cut, the less paring (if any) you'll have to do to fit the boards together.

*A friend accused me of never posting anything that I've screwed up. So here it is. Because I'm missing a math gene, my boards are not aligned along the top and bottom edges.

To transfer the tails' outlines to the front board, I aligned the top and bottom edges as I would with a square project. But bevelled sides require that the boards be offset when you transfer your marks.

I still don't know the equation to figure out the measurement for the offset, but fortunately the depth doesn't matter in this project, so I can plane the top and bottom edges to match.

There's also a gap in the top pin. But it's nothing that a little well-crammed wax can't fix once the project is finished.

Small Wood Mallet

I plead ignorance.

When a friend watched me set both the iron and the wedge on one of my handmade planes with a metal mallet, he said "You're supposed to use a wood mallet to tap the wedge and plane body."

"Yeah. Well, I sort of like the tool marks on the backs of my planes," I insisted.

He gave me a look that said he knew I was bluffing; that I really had no idea you should switch mallets mid-adjustment.

I've been abusing my planes this way for years and they have the half moon marks to prove it. I've even all but obliterated my name on one of them.

Little wood mallets come in handy for more than just plane adjustments. They're also helpful with driving in & removing the wedges from tusk tenons, and joining dovetails & finger joints. And it was high time I made one.

The element that's lost in small wood mallets, though, is weight on the hammer end. So I chose to make the handle from cherry and the hammer head from rosewood. Rosewood is heavy and dense, which can damage a project in use, so I decided to buffer the blow with cherry pads glued to each end.

I referred to a tack hammer's handle as a template, rough cut the blank on the bandsaw, and finalized the shape with a sanding drum chucked into my drill press.

A wedged through-tenon is an effective way to secure the hammer head to the handle. First, drill a hole at the lower end of the tenon so it won't split when you drive the wedge in. Then saw a kerf down the middle of the tenon.

The 6th photo shows the [slightly] loose-fit tenon that provides wiggle room for the wedge. Cut the wedge with your tool of choice; I used a Japanese dozuki. Add glue to the tenon, mortise, and wedge, and then hammer the wedge home.

Two cherry pads and three coats of Watco Wipe On Poly later, and my wood mallet and handplanes are playing nicely together.

And I can finally remit my H.A.A. (Handplane Abusers Anonymous) member card.
