Beginning Woodturning: Four Tips Before You Get Started

As you look at a bewildering display of turned wood objects and an even more bewildering display of woodturning tools, it can quickly get discouraging to consider getting started turning wood at all. However if you look at the wide array of people who turn wood you quickly realizes that woodturning is an accessible hobby for just about anyone. The real question is how to get started. Here are four quick and easy ways to begin the entry into the world of wood turning and working on the wood lathe.

1.First take your time. Do not rush out and buy the first lathe you come to just to find out it is not suited for the objects that you would like to make. Read a few books on woodturning. Most libraries have one or two and maybe even a video to watch. It may be for a more advanced turner but will certainly give you some ideas of what you are getting into. Look for the basics such as what tools are needed and what kinds of wood lathes are available. Remember that you are starting out and all the bells that whistles that the pros like are probably not necessary for you.

2.Once you get a feel for the basics, consider what you might like to make for your own purposes, be they gifts, table legs for other projects, pens or whatever. Think of what accessories you might need other than the lathe or turning tools. Budgets start to come into play here. You might be able to find specialized books on your choices or even classes at the local community college or school dealing with this particular interest.

3.Consider taking a class in woodturning. Many woodworking classes in night school will have a lathe available and may have an instructor that knows how to use the machine. In addition look for a woodturning club in your area. A lot of communities have them and most have a fair number of watchers and even members who do not turn but are considering getting started. As a rule, woodturners like to demonstrate their skills and introduce others to the art and craft.

4.Stay safe as you start. Get a face shield and dust mask and use them. Hearing protectors are great too. While most lathes are fairly quiet wood shop tools, most wood turners will use chainsaws, band saws, planers, drills and the like with all the noise they provide. Safe woodworking is by far the most enjoyable.

These simple tips will get you started as you begin the interesting and compelling art and craft of woodturning. Soon you will be giving tips to someone else with the same interest.

Mounting Wood On The Wood Lathe: Do Not Forget The Jacob's Chuck


   One of the best and worst things to happen to modern woodturning is the invention of the four jaw chuck for holding wood. While it is a great addition to the woodturner's asenal, it is also an expensive tool and many beginners find that it costs more than their wood lathe. Also, like many tools a cheaper version is aggravating and in some cases simply dangerous to use. One thing to remember is woodturning has been around for thousands of years and there are many ways to mount the wood without the newest fashions. The Jacob's chuck is a great tool for all turners.
   A Jacob's chuck is designed for holding drill bits. It is the chuck on the end of the drill press or the electric hand drill. As such it is often used held in the tail stock of the lathe to hold a drill bit for putting a hole in a piece of wood in the head stock or vice versa. However, it may also be used to hold a piece of wood for turning.
   The difficulties in using a Jacob's chuck for holding wood are
  1. its size which is generally limited to one half inch although slightly smaller or larger ones are available for some lathes
  2. its having three jaws which make it awkward to hold onto a square piece of wood
  3. it is made for holding metal and may well crush the wood in its jaws
These limitations are easily dealt with.
   The time to use a Jacob's chuck is generally to turn a spindle that needs to be held on one end only. This means that the stronger grain orientation of long grain is being used as opposed to face grain. In such circumstances a piece of one half inch wood such as maple is easily strong enough to support a three inch spindle of reasonable length. It remains to mount the spindle first between centers and turn it round, allowing for a short length at one end to be turned down to one half inch so as to fit in the chuck. Now it can be remounted in the chuck, trued up and finish turned.
   Note that this also removes the second difficulty of trying to fit a square piece of wood into a three jaw structure. The tenon to fit the chuck is now round. It also deals with the third problem of crushing the wood. This would serve to mar the wood and also to move the piece off center for turning. A truing cut will put it back on center and the tenon is considered waste wood and removed from the finished piece.
   The old and established technology of the Jacob's chuck is not as versatile as the newer four jaw chuck but it is reliable at a much lower cost and opens new avenues of wood turning to the beginner without a lot of expenditure. Besides which, a Jacob's chuck is a welcome addition to every turner's arsenal.

Five Tips for Sharpening Your Wood Turning Tools


One of the first things that woodturners realize, especially if they come to woodturning from other types of woodworking, is turning tools need to be sharpened early and often. In most cases they need to be sharpened a lot more often than other cutting tools and the skills needed are different than those to sharpen most other tools. Here are five tips to help get sharp tools quickly and easily for the wood lathe.
First of all there is the need to recognize a couple of angles, thirty and forty five degrees. Almost all cutting woodturning tools will use these angles and the few that do not will be glaringly obvious. Gouges and skews cut wood. Roughing gouges and bowl gouges are generally sharpened to forty five degrees and straight across. Many woodturners start with spindle turning and spindle gouges are sharpened at thirty degrees. Some turners try to sharpen roughing and bowl gouges to that same thirty with terrible results and are amazed when someone shows them the magic of forty-five.
Second is the need to keep things simple, especially at first. Stick to what has worked for centuries. Woodturning is over three thousand years old and most of what is done is tried and true. This is not to say that there have not been changes but it is good to start with the established norms before branching out. For instance, there is the other typically used grind for a bowl gouge that has long wings and a bevel that alters from about forty five at the edges to seventy in the center. A straight forty-five works beautifully and is a lot easier to do at first.
Then there is the sharpening of scrapers which are the real exception to what appears to be a sharp edge. They are sharpened almost square at about seventy to eighty degrees and the burr that is raised is the cutting area. It is quickly broken away and resharpening is needed often.
This brings up the fourth tip and that is to be satisfied with an edge that is sharp enough to remove wood and still hold up to the punishment of woodturning. For this a grinder is the best tool to use as a sharpening station. Equip it with an eighty grit aluminum oxide wheel and ignore the usual whet stones and honing strops. It can take a lot of time to get a razor edge that will disappear in the first second of turning.
Fourth, use a jig. Freehand sharpening is an art and craft in its own right and it is easier to learn to turn with sharp tools from a jig rather than trying to learn both crafts at once. Jigs will also teach the movements that are needed for freehand turning if the need arises. They can be either cheaply made in the home shop or purchased from just about any woodturning supplier.
Fifth and perhaps most important is to relax and take it easy in the sharpening. It is a part of the turning process and meant to be enjoyed. If an edge comes out wrong it is a simple matter to try again. A little time, a little attention and a little steel and back to the wood again.
Sharpening is not hard and woodturners have been getting a sufficient edge for over three thousand years. With a little practice you will be joining the group and the shavings will fly from a good, sharp edge.

Basic Equipment You Will Need to Start Woodturning Projects

 While it is easily understood that a wood lathe is needed to begin woodturning projects, there are a few other necessities before starting. Many of these are already found in the typical woodworking shop while others will need to be purchased.

The basic wood lathe comes with one or two faceplates for bowls and other large work; a spur center and tail center for holding spindle projects; and a couple of tool rests for different sized work. No cutting tools are generally supplied with the lathe.
While experienced turners will purchase individual tools, it is advisable for the beginner to get a beginning set. This will contain the necessary tools for spindle work. Usually this will be a roughing gouge, a couple of spindle gouges of different sizes, a couple of skews of different sizes, a couple of scrapers of different sizes and a parting tool. Such a set should be high speed steel, not carbon steel which is cheaper but does not hold an edge very long compared with high speed. Later on bowl and faceplate tools can be purchased or made. If the beginner is anxious to begin turning bowls, a one quarter inch bowl gouge will get them started and different sizes can be purchased later on.
Once the tools are purchased there needs to be a means to sharpen them. Woodworkers new to woodturning will be amazed at how often turning tools need to be sharpened. The usual means to a good edge is a grinder however most shop grinders have wheels too coarse to give a good edge on high speed steel. An aluminum oxide wheel of appropriate size should be purchased. It should be around eighty grit and a wheel dresser to keep it round and clean is really a necessity.
While some turners consider a sharpening jig to be a luxury, for a beginner it is almost a necessity. Sharpening woodturning tools freehand is a skill in its own right if not an art. Learning it at the same time as trying to learn woodturning is difficult and learning to turn with dull tools is almost impossible. A jig should be purchased or made at the very beginning.
One of the things that makes woodturning special is the ability to much of the time sand and finish a project on the lathe. Sandpaper in grits from eighty to two hundred twenty is usually found in the workshop but some turners like to go as high as two thousand grit for some projects. Generally up to three hundred twenty will be fine. Danish oil and similar finishes work well for most woodturnings and again is a typical supply of most shops.
Safety is an important part of any woodworking shop and work around a wood lathe is no exception. A face mask to protect from flying wood is a necessity as is a dust mask to protect the lungs from sanding. Hearing protectors are good to have. Most lathes are fairly quiet but saws, drills, sanders and dust collectors as well as other shop tools can cause hearing problems.
Tools to ready the wood for the lathe will likely be already in the shop. Bandsaws and table saws are often used and a chainsaw is a part of most woodturner's arsenals of tools.
A quick look at a woodturning catalogue will convince any aspiring woodturner that bits and pieces can be acquired for years to come but these should get one started. Certainly a lot of enjoyment are contained in these few simple items.

Sharpening Woodturning Tools: Making Sense Of Grinder Wheels For Sharp Wood Lathe Tools


Getting a good edge on a wood lathe tool is one of the great difficulties for a beginning woodturner and an ongoing concern for intermediates and experts. While the grinder is the tool of choice for woodworkers sharpening tools for wood lathes, getting it set up with the correct wheels can be a confusing challenge. It need not be with a couple of simple steps.

First it is necessary to move in thinking of the grinder as a sharpener. Many people come to woodturning from general woodworking where the grinder is used to remove lots of metal in a hurry so as to grind away nicks and breaks in chisels, plane irons and the like. Water stones and honing implements are used for final edges. Woodturners move from the grinder to the wood. Most shop grinders are not set up for this and the problem is largely the wheels.

Thus the second consideration is to replace the grinder wheels. While it is agreed that since woodturners generally use high speed steel tools they should have aluminium oxide wheels, there is a lot of confusion in the catalogues as to what color wheel to get and what bond to have. The color reflects individual manufacturers attempts to make choosing between grades of their particular wheels and has little to do with other wheels on the market. Consideration then should be given to grit and bond.

The bond of a wheel refers to how friable the material is that holds the aluminium oxide together. More friable bonds allow the material to break away quickly thus leaving a sharp cutting and cooler grinding surface. Unfortunately, the most friable bonds manufacturers recommend for woodturners groove, pit and wear quickly requiring a lot of wheel dressing and expensive replacement. Thankfully, almost any aluminium oxide wheel generally available to the home market is sufficiently friable for good sharpening with good wear so making sense of the friable numbers of bonds is not necessary. Just get a good wheel.

Third is consideration of the grit. While it may encourage argument, a good setup is a fast cutting wheel of about 46 grit on one side of the grinder and a sharpening wheel of eighty to one hundred on the other. With a good jig especially, this will meet all the shaping and sharpening needs of the woodturning shop.

Simply put, a couple of inexpensive aluminium oxide wheels of appropriate grit will give a lot of sharpening satisfaction and help to make a lot of shavings for a long time to come. Keep it simple and keep it fun.
