Lathe Chuck

Your tailstock will have a taper probably a morse taper 1 or 2. You’ll need to know that when buying a center etc. The universal scroll chuck can be used to hold and automatically center round or hexagonal workpieces. If this happens, the work must be removed from the chuck and the point extracted. If you want to try and use a metal lathe chuck on your threaded spindle, you will have two different options. References, charts, tables, and other predetermined data on machine operations may be useful to lathe operators. The ends of the mandrel are smaller than the body and have machined flats for the lathe dog to grip. It can be have a straight or a tapered holder depending on the type of drill chuck you are using.

Use paper or brass shims between the work and the faceplate to protect the delicate surface of the faceplate. Failing to research beforehand may result in a wasted purchase or a discrepancy between the type of lathe and the user’s skill level. Two separate procedures are given, one for a screw chuck mounted on a faceplate and another for a screw chuck that is mounted in a scroll chuck.

The chuck face is scribed with concentric circles which are used for rough alignment of the jaws when chucking round workpieces. The jaws expand into the recess to hold the work and like the tenon, the jaw faces resist lateral forces so it is important that they bear squarely against the wood surface in the recess. You know, you can make lots of chips on your wood lathe with a face plate for bowls and such. The dovetail shape provides a mechanical connection between the jaw and the work-piece. I could just ‘pop’ each jaw out, in place, and then I could slide the new one in while still on the lathe.

Gripping only at these points (eight in contracting mode, or four in expanding mode) is less secure and risks marring the wood. These collets are externally threaded onto the lathe and usually have a holding capacity that ranges from zero (0) to seven (7) inches in diameter. The jaws move independently so you can use odd shapped material or dial it in for zero tollerances (run-out).

I like to refine the outside of the bowl a bit, but I always leave sufficient wood on the shoulder next to the tenon. Remove the bowl blank, attach your chuck to the lathe, then mount the bowl blank onto the chuck. Keep in mind that you will use this thing for much more than rod building as time goes on. Like many other aspects of the craft, everyone will have their favorite way to do things but it is by no means the only way to do things. The products the user intends to make will also affect which wood lathe is best for their circumstances.

A quality wood lathe will allow the turner to work quickly and efficiently while also taking most of the physical effort out of the process. After the workpiece is center-drilled, place a lathe dog (that is slightly larger in diameter than the workpiece) on the end of the work that will be toward the headstock, and tighten the lathe dog bolt securely to the workpiece). This is all to say that what is properly called a scroll chuck is an easy sale to a turner — whether novice or seasoned veteran — walking into a woodworking supply store.

I’ve gathered so far I need a self centering 4 jaw chuck that can be set with one hand and that can both grab a rod and a square wood blank but I am getting lost in all the possibilities and various adapters. The three bronze self-centering jaws of the chuck will accurately close upon workpieces between 1/4 and 1 inch in diameter. Spin the workpiece by hand and make approximate centering adjustments as needed, then firmly tighten the jaws. A greater swing allows for wood blanks with larger diameters that will not contact any other part of the machine. I just use a square and draw the diagonals to get the center, close enough on raw stock.

The workpiece moves relative to the bearing surface, the screw gets tighter and tighter until finally the wood surrounding the screw strips out. Again, create a tenon on the work piece and drive it into the wood chuck, which is screwed to a face plate. Infinity Saw Tooth Chuck Jaw designed for aggressive holding of spigot (tenon) turnings like goblets, hollow form vases & urns. You haven’t lived until you’ve seen a chuck wrench go through a block wall when the lathe is turned on inadvertently. Lathe tool holders are designed to securely and rigidly hold the tool bit at a fixed angle for properly machining a workpiece (Figure 7-14).

If your turning skills are highly refined then you might be able to get away with using a metal chuck, but everybody I know who has used them back when there were no real woodturning chucks say to forget about trying to use them because it is a very good way to get a serious injury or even kill yourself. The chuck that I ordered will do what I wanted it for, no problem.Quality of the chuck seems alright. It is a durable wood lathe made of solid cast iron, but it is light enough that it will require weight at its base to keep it steady.

Tool bit shanks can be 1/4-inch, 5/16-inch, 3/8-inch, and greater, with all the various sizes being manufactured for all the different lathe manufacturer’s tool holder models. I did not own a chuck for several years, but major makers back then were Axminster, Nova, Oneway, and Vicmarc. Find the center of any round or square stock for lathe turning with a center finder tool.

Drill chucks are designed to hold the bit tightly and not loosen, even when there is a high amount of torque. As a safety note, never use the side of the grinding wheel to grind a tool bit, as this could weaken the bonding of the wheel and cause it to crack and explode. Other tool holders to fit the standard round tool post include straight, left, and right parting tool holders, knurling tool holders, boring bar tool holders, and specially formed thread cutting tool holders.

Each aspect of the machine will determine how well the wood turner will be able to use it or how satisfied they are in the long run. A set of soft jaws on a chuck with a matching tenon on the wood is a safer set-up than a wood chuck which isn’t nearly as stiff and generally has far more runout. A great starter item for a beginner would be the PSI woodworking LCHSS8-HSS wood lather chisel 8 piece set This kit is ideal for people wanting to turn small pens, spindles, bowls, and larger projects.

Lathe centers must be parallel with the ways of the lathe in order to turn workpieces straight and true. Once you have the stock sized at each diameter, use scraping tools to shape the stock between cut diameters. Incidentally, tallow is the stuff to use when tapping aluminium components that are to be anodised – it doesn’t interfere with the anodising process like some commercially-available tapping compounds. The chuck housing has a handwheel on the outer diameter that turns to tighten or loosen the tapered spindle which holds the rubber flex collets. Perform a finish cut, flip the piece over, and change the lathe dog to the opposite end.

Single-key chucks offer the advantage of one-hand operation without the necessity of locking the lathe spindle. For these workers, mini wood lathes come in handy as they are specifically made to be used with smaller items. Centers, collets, drill chucks, tapered shank drills and reamers may be inserted into the spindle. It is also used for internal threading operations where the workpiece projects a considerable distance from the chuck or faceplate. To properly accomplish facing between centers, the workpiece must be center-drilled before mounting into the lathe.

Dismantle the slide, clean it carefully (use a scriber to get compacted swarf out of the dovetail recesses) and reassemble with care and lots of oil; it will make a great difference to the feel of the slide. Usually the existing jaws have threaded holes to attach soft jaws or the outer jaw is easily removable to replace with soft jaws. One method is to use a parting tool bit to locate and cut to depth the position of the shoulder.

Timber lathes may be used to create useful furnishings additives, lovely decorative timber tasks inclusive of candlesticks and bowls, or. Lathe wood tasks (with photos) ehow. When you cut square stock for mounting in a chuck, make accuracy a priority; out-of-square stock is difficult to grip securely.
