A slower feed rate will also remove less wood per revolution, making thinner, weaker shavings which bend and break easily without much leverage on the fibres not yet cut. Make sure the bevel is properly aligned with the surface underneath, without pressing on the wood. If the heel of the bevel lifts from the surface, it changes the top rake angle and the shaving has to bend more to get over the wedge and into the gouge flute. On the inside of the bowl, a short bevel will fit the curved surface better than a long one. If your best efforts still leave some tear-out, you will need to sand to remove the damage and any tool marks. A minor inconvenience is that when grinding different tools at the same time, the platform angle may have to be changed, which means the wheel has to come to a stop for the angle to be reset accurately. CBN (cubic boron nitride) grinding wheels are said to have advantages for grinding woodturning tools. The grinding angle is quite obtuse, like a scraper, and the tool looks like a scraper, but is not used like one.
Its cutting action is like that of a traditionally ground bowl gouge, with the wing close to the wood surface. Then I turned an ash dowel to be a snug fit in the tool rest holder (banjo), and made a 25 mm x 25 mm tenon on one end.
A screw is often supplied with ordinary jaw chucks so they can be used as screw chucks for bigger items, but they are usually large.
Choose a screw with a threaded portion longer than the cylinder and insert it from the back Screw it right through until the point protrudes about 20 mm from the front. There you can see my work, buy great gifts, and find lots more information about woodturning, including pages on tool sharpening, bowl troubleshooting, finishing methods and more. Whether you need to turn porch posts or like to mount chunks of tree trunks on the 29" outboard faceplate, this is one heavy duty lathe. Included are the lathe, 2 tool rests, floor stand with 2 tool rests, 3 faceplates, and complete countershaft assembly.
It allows you to optimise the top rake angle and improves support and guidance of the tool.
Any sharp edge will cut the fibres, but a smaller bending angle for the shaving will reduce the pull on the fibres.
They have to be secure, particularly if you run the lathe in reverse, so can get too tight to remove easily. It should go round about a quarter of the circumference, the rest of the rod remaining straight to form the handle. With the angle set, the tool simply rests on the platform while the grinder does its stuff. The method often recommended for setting the platform angle is to match it to the existing tool bevel, inking the bevel where it touches the wheel for greater precision. I removed some small burrs from the old wheel bushes that made them too tight for the new wheel. This makes grinding easier as there is less tendency for careless use to allow a gouge held in a grinding jig to fall off the side. This time, the cutter and the end of the bar were resting on the firebrick surface instead of being in free air. For a long time I have used a 2HP cyclone system with four felt tube filters hanging from a homemade plywood distribution box.
A wooden post is held upright by standing it in a bucket of loose gravel on the floor behind the headstock. Possible improvements might be to make the arm telescopic and adjustable for height, but at present it seems fine as it is.

My extractor hose is there at the lathe and works quite well in its normal position, but would probably be better with the intake under the sanding table closer to the downward dust stream.
Many turners use a screw chuck, which is a single-screw faceplate, for small items because it is so quick and easy. The extra tool rest base for the double rest has an old weld repair and has a hex nut rather than a square nut as on the other base.
If the edge is skewed, the wood sees the sharpening angle as smaller and more acute and the shaving slips over the edge more easily.
Unless the bar is stout it will bend, and if the hole for it is shallow the metal around it will distort. I hot forged mine by making the end of the rod red hot with a blow torch, then hammering it into an L shape. This is best done with the metal red hot, which would need a large burner or a small homemade forge, but the rod could be bent cold if you have a heavy vice.
The process is extremely simple, and platform sharpening is the best method I know for scrapers, skew chisels and square-ended gouges (some people hone the tools to refine the edge, but most probably use them straight from the grinder).
I find the sound of the grind when the wheel is turned slowly by hand more helpful than the ink – when just the heel or the edge is in contact with the wheel, the sound is harsher and more grating than when the bevel rests properly on the wheel. You need a light touch on the grinding wheel, which is not easy if you are holding the tool firmly in place on the platform. I did that by holding the steel bushes in my woodturning chuck and skimming them very lightly with a graver.
As the abrasive layer is very thin, it is not possible to true it up with a diamond dressing tool, as could be done with a conventional wheel. To make things more manageable, I recently fitted mobile bases to some of the equipment, including to some big racks I built for materials and part-finished work.
The second and third were pairs of rollers of the kind used for kitchen appliances, which I put under the bandsaw and the router table. The simplest construction is a square of plywood for the item to stand on, secured in place, with a caster under each corner.
Some turners use scrapers like that, but only if the tool is turned on its side, never flat on the rest as that could cause a severe dig-in.
But the shape of the fluteless gouge puts the shaft nearly perpendicular to the wood surface, reducing any tendency to vibration. The tip had been stuck on only by the melted flux, because the steel bar had not been hot enough for the brazing metal to run under the tip. I had a 7 inch pipe running across the ceiling with smaller branches to the lathes, bandsaw and drill press. I cut a hole in the sheet metal of the lower stand and bolted on a flanged adaptor for a 5 inch hose.
I have only once allowed it to overflow and fill up the filters, but now I no longer have to keep opening the bin to check. The suction falls off very rapidly with distance, and has to compete with air movement caused by the spinning wood or sander.
I pressed it face down under weights for a few minutes to get a good bond, trimmed the surplus, then applied the loop-backed sanding disc.
I think long jaws with a parallel grip are best for the job as they give good support to the wood.
Rests of different lengths are always useful and a short one is handy when you have something held in a chuck with tailstock support and don’t have room for a long one. A lot of chisels are sold with raw, sharp edges and are almost unusable until they have been fettled, as well as damaging the toolrest.

If you sand just the defect you end up with a depression, so you have to sand away the surrounding high areas too – but sometimes you can get away with spot sanding with the lathe stationary, then blending it in with the lathe running. The platform can also be used for other gouges once the knack of coordinated swinging and twisting the gouge is learned. The tools were sharp after this, but I can’t say they were sharper than the old ruby wheel achieved. In one way, this is helpful as I can sharpen small tools as the grinder is running down, the equivalent of a slow-speed machine (my grinder runs at high speed). But suitable casters are several inches in height and may make tools too high for easy use, and less stable. The fluteless gouge must also be rolled on its side so the lower part of the edge is nearly vertical and slices through the wood. As the extractor has a 7 inch inlet, I decided to extend the full size duct right to the lathe. It’s easy to get the inlet close enough for small spindles, but for faceplate work and larger spindles it can be difficult. The post has a projecting arm at about the height of the lathe spindle, at the end of which is a wooden cradle to support the hose, which hangs down from above.
Today though I spent some time polishing the tool contact line. I started with a fine file, then abrasive paper, and finally used a buffing wheel with steel-cutting compound, aiming for a mirror finish. High carbon steel can be hardened and tempered, but I used a bit of scrap mild steel unhardened and it seems to be quite strong enough for light duty.
They are suitable for high speed steel and hardened carbon steel, but unhardened steel is said to clog them. I used a reciprocating saw to cut a length of 30 mm mild steel bar for the stem, sawing it at an angle.
An alternative to a platform for large tools is to use a long arm jig that supports the end of the handle only. An unenclosed wheel seems likely to disperse grinding dust more widely, and because they take a long time to stop, they may come into contact with something while still spinning.
I would rather take it slower when reshaping a tool and have a more gentle and controllable grind when sharpening. A mobile workbench or any machine which will need to resist sideways forces would need to be wedged carefully to lift the wheels clear of the floor. This lathe would have originally been sold without a bed with the user building his own wood bed of any desired length. If the platform angle is always the same, any one tool placed on it will always be ground the same, although the bevel angles may not be the same on different tools because the edge of a thicker tool will be higher on the wheel.
Although the grinding angle is obtuse, the wood coming onto the slicing edge sees it as very sharp. I can pull the arm to turn the bucket to any position, or slide the bucket to move the inlet along the lathe bed. There are plans available for trolleys that lift the item for moving and let it down again when in place.
