If you've ever stared from a stack associated with purple heart bowl blanks plus wondered if that vibrant violet colour is actually genuine, you aren't alone. The first time I saw a piece of this wood on the lathe, I believed someone had played a prank with a bottle associated with wood stain. But nope, that's just nature showing off. It's one of individuals rare materials that will makes people cease and ask, "Wait, is that actually wood? "
Turning purpleheart is definitely a bit of the rite of passage for woodturners. It's dense, it's persistent, and it'll give your tools the run for their money, but the payoff is incredible. In case you're thinking about collecting some blanks for the next task, there are a few things you should know before you start making shavings travel.
Picking the best Blank for Your own Project
When you're out shopping—or more likely, scrolling by means of an online wood shop—choosing the proper purple heart bowl blanks is about more than just finding the brightest piece. You've got to believe about the grain and the moisture content.
Many of the period, you'll find these types of blanks kiln-dried. That's a very important thing because purpleheart is notoriously firm. If you try to turn it natural, it can end up being a bit of a rollercoaster as it dries. Considering that it's so heavy, it doesn't like to move much, meaning if it decides to crack, it's likely to crack huge. I usually look intended for blanks that feel heavy for their dimension; that density is usually what gives the finished bowl that will high-end, polished feel.
Also, get a look in the grain positioning. If you want those traditional "shimmering" chatoyancy ranges, search for blanks with a bit of figure. Simple grain is great, but when purpleheart has some wavy fibers, the way it catches the particular light after a few coats associated with finish is just stunning.
The particular Reality of Turning Purpleheart
I'll be honest together with you: purpleheart is tough. It has the high Janka hardness rating, which fundamentally means it's like turning a rock and roll compared to something like walnut or maple. If your tools aren't sharp—and I mean "shave the particular hair off your arm" sharp—you're heading to possess a poor time.
A single thing you'll notice pretty quickly may be the smell. It's pretty good, but it's distinct. Some people state it smells the bit spicy or even like vanilla, while others find this a little pungent. Also, be prepared for the dust. Because the wood is so dense, the sawdust is okay plus tends to get everywhere. And yes, it's purple. You'll probably leave the shop looking like you've been battling a grape fruit juice monster.
Managing the Heat
Warmth can be your biggest enemy whenever using purple heart bowl blanks . Since the wood is definitely so hard, rubbing builds up fast. In case you let your own bowl gouge or scraper get too hot, you'll really see the wood start to "burn" or even glaze over. This is especially true when you get to the sanding stage.
In case you sand too aggressively or utilize a high speed on your lathe, the heat can cause the natural oils in the wood to rise in order to the surface, which usually can mess with your finish later on. I always tell individuals to slow the particular lathe down and use light pressure. It takes longer, but you won't ruin the piece you simply spent 2 hours shaping.
The Secret to the Perfect Purple
Here is the particular thing that journeys up most newbies: when you cut in to a purpleheart blank, it's often a dull, brownish-grey. Don't panic! You haven't been scammed. The wonder happens through a procedure called oxidation.
Once you've turned your bowl in order to its final form, the wood has to "breathe" and observe the light. Within a few hours or even days of being exposed to air and UV light, that dull brown transforms directly into that deep, regal purple we just about all love.
However, there's the catch. In case you depart it in the sun as well long, it can eventually reverse to a dark brownish or perhaps a charcoal colour. It's a little bit of a handling act. The trick is to allow it to reach that maximum purple stage and after that seal it with a finish that has UV inhibitors. This helps "lock in" the colour so your bowl doesn't turn in to a generic dark brown dish five many years down the road.
Finishing Methods for Purpleheart
Speaking of finish, everyone has their own favorite method, but purpleheart can be fussy. Some people recommend friction polishes simply because they give it a good immediate high gloss. Personally, I like utilizing a high-quality tung oil or a wipe-on poly.
The oil really brings about the level of the grain, making the purple look almost three-dimensional. If you're making something that's purely ornamental, a lacquer finish off works great as well. Remember whatever you use, the objective is to guard it from the air and sun as much as possible to protect that color.
A Note upon Tool Maintenance
I can't stress this enough: keep a sharpening stone nearby. When you're working through purple heart bowl blanks , you'll find yourself going back to the particular grinder far more usually than you will with cherry or maple. The silica content in some exotic hardwoods can dull a steel advantage surprisingly fast. If you utilize carbide-tipped tools, you'll have an simpler time, but also those will sense the "drag" after a while.
Why Bother With This kind of Hard Wood?
A person might be thinking why anyone deals with the dust, the dull equipment, and the color-fading drama. The solution is straightforward: there is nothing else like it.
Whenever you pull a finished purpleheart bowl off the chuck and hold it in the light, the energy feels worthwhile. It has a weight and an existence that cheaper forest just don't possess. It's a "statement" wood. Whether you're selling your work at a craft fair or giving it as a present, a purpleheart piece is always the one particular people wish to touch and discuss.
It also sets beautifully with some other woods. If you're feeling ambitious, you can glue up some purple heart bowl blanks with items of maple or yellowheart in order to create a segmented bowl. The contrast between your creaminess of the maple plus the intensity of the purpleheart is usually a classic look that never will get old.
Gift wrapping Things Up
If you're prepared to graduate from much softer woods and desire a challenge that will offers a massive visual reward, get a couple of purple heart bowl blanks and give them the spin. Just remember to keep your own tools sharp, be careful about your heat while sanding, and be affected person using the color change.
This might be a bit more work than your own average project, but once you see that deep purple grain shining under a fresh layer of finish, you'll be hooked. Just don't be amazed when your buddies start asking you to make them one, too. It's a bit associated with a shop addiction—once you start turning the purple things, it's hard to go back in order to common brown.
