lathe
How much does a lathe cost?
I am looking to buy a metal lathe for a reasonable price. Can someone show me a good one please (looking for the one that's built onto a table so you can change speeds with the belts)
Assuming you are in the US. Then I would look at http://www.harborfreight.com, and search under lathe.
All small lathes (low cost) are made in China or at best Taiwan, so the quality is a bit limited. If you have more space and can deal with the weight issues, then I would search out an old EMCO lathe on ebay.
You could ask this question in a 'model builders' forum, they are likely to have explicit knowledge of the lathes to watch out for.
Also: http://www.taigtools.com, these might be a bit over budget, but they are fairly well respected in the modelling world I believe.
INDICATING PARTS IN THE LATHE QUICKLY
While one of the great advances in woodturning in recent years has been the development of the four jaw chuck to mount wood for turning, the price tag on a good chuck is a shock to many turners. In fact the price for a decent four jaw chuck often accedes the price of many starter lathes. One of the things that a wood turner needs to remember when going into faceplate turning is the use of the old fashioned glue block for holding wood.
The use of the glue block arises from the desire to not have screw holes observed in the bottom of such items as bowls and platters. Generally such an item is made by first rough turning it from green wood and then letting it dry in the shop for some time. Later it is remounted to the wood lathe and finish turned. It is during this remounting that it may be screwed to the faceplate, thus leaving holes in the finished product. These holes then have to be filled or covered in some way. In addition, the length of the screws determines a certain depth of wood that cannot be used or the tools would hit the screws themselves.
A simple solution, and one centuries old, is the use of a glue block to hold the wood to the lathe. First the bottom of the bowl is flattened using a plane or other tool. Second, a waste block of wood is screwed to the faceplate. Third the waste block is flattened. Third, the waste block is glued to the bottom of the bowl using carpenter's white glue.
Generally a piece of craft paper is glued between the waste block and the bowl. This enables the bowl to be finish turned and then a chisel blow between the block and the bowl splits the paper down center. Then the waste paper can be sanded from the bottom of the bowl and the bottom finished. If desired, the paper could also be removed from the waste block and it could be used again.
There are a few draw backs to this system. While glue has a great hold but it needs to be clamped and let dry for at least eight hours. Also, the wood used has to be dry so this can not help with green turnings. In addition there is the fuss of sanding away all that glue and paper, a combination known for quickly clogging sand paper.
Thankfully, a couple of modern glues rise to the occasion. When turning dry wood such as a dried bowl blank, hot glue can be used to glue the wood block to the bowl. Withing a couple of minutes it is ready to mount on the lathe and turn. Either the block can be parted from the blank with the lathe running or the whole assembly can be taken off and the waste block removed with a a sharp rap of a chisel at the glue line. Any remaining glue is easily pealed off.
Similarly a medium thick cyanoacrylate glue can be used to bond a green blank to a waste block. The glue is applied to the waste block and accelerator to the blank and the two are pressed together. Again, a couple of minutes are sufficient to hold the work for turning and again a sharp blow at the glue line will separate them after the turning is done.
Modern adhesives simply allow the old methods to work in today's shops. While the technology advances us a little we are still working in the historic fashion. The old ways may not always be the best, but they certainly work and work well.
Darrell Feltmate is a juried wood turner whose web site, Around the Woods, contains detailed information about wood turning for the novice or experienced turner as well as a collection of turnings for your viewing pleasure. You too can learn to turn wood, here is the place to start. Wondering what it looks like? There are many free videos on the site dealing with everything from sharpening to making a bowl.
There are several wood turning projects fully explained on the web site. In particular, a selection of beginner's projects may be found on the Beginner's Projects page complete with explanation and step by step photos.
