Operating A Jointer

So here are a couple of articles on operating shop equipment, one for the woodworker and one for the metalworker.

The first is on operation of the jointer. The jointer and planer compliment each other in producing straight and accurate 4 sided boards. This is very important in furniture construction and laminated glue-ups. In my opinion, if your finances require you choose between the two, the jointer is preferred by a stretch. You can do all four sides on a jointer (though the two wide sides may not be perfectly parallel). The planer will only do the wide side parallel to the side done on the jointer. You can do both wide sides on the planer, but it will not take wind out of the board without first doing one side on the jointer.

This comparison aside the jointer can do many other operations, as described in the following article from the Winter 1954 PM Shop Notes.

Safety is very important in the operation of a jointer. Check that the guard is working properly and never pass your hands over the cutter head while pushing a board over the cutter head. For shorter boards, make and USE a work hold down like the one illustrated in fig. 7.

Finger Joint Machine And Router Table

So here are a couple of nice plans from the 1987 Popular Science Supplement. The first is a finger joint cutting machine. There are many nice plans out there for finger joint cutting jigs. Most use the table saw to do the work with various blades, blade stacks, or dado stacks. Some are more complicated than they have to be and do not have much adjustment to compensate for things like, blades that run less than true.

If you have a bit of floor space and like to use finger joints for lots of joinery, this dedicated little machine might be for you. A 1/2 hp or larger motor, a ball bearing spindle available at most hardware stores, and a good quality 6" dado stack are the main parts needed. The rest can all be easily shop built. There is lots of adjustment, so once you have set up a snug fit, you can quickly start to produce stacks of finger jointed boards. As the author alludes to their are other applications this can be used for.

My feeling is that safety was a consideration in the design, the blade lives below the table, it is raised into the work with a simple foot pedal feed, and returns below the table, when the pedal is released. Additional guarding on the underside would insure nothing wanders near the blade from the underside.

The second project is a uncomplicated router table by R.J De Cristoforo. The table has nice built in storage and guards for the different functions, the top is solid looking. What more do you need? Some plans offer more in eye appeal but function no better for their intended purpose. A characteristic of R J's designs, I find, often omit unnecessary additions that don't contribute to tool function.

An Inexpensive Panel Saw

So power is back on. I would like to think they replaced or repaired the piece of equipment that has caused some resent surprise outages, but more likely they were just reconnecting the cottagers for the season. The grid has been neglected for so long it's like an old car, when things start to break down, it's one thing after another.

So here is a plan for an inexpensive panel saw. Short of industrial equipment, its hard to find something easier to break down large panel material, than with a panel saw. Purchased units are quite expensive and many diy plans are built for heavy use. I have at least one for a future upload. This plan is inexpensive and relatively easy to build. For the home DIY'er who occasionally has need to break down sheet materials, this will simplify the process and save you lots of time.

This is another project from R.J. De Cristoforo published in the 1985 Popular Science DIY Yearbook.

R. J. is no spring chicken at this stage of life, but he makes it look easy to use the panel saw to break down full size panels.

Woodworking Machines-One Mans Viewpoint

So here's some light reading that woodworking machine enthusiasts might find interesting. The article was in FWW # 30, 1981 and written by John Lively.

In the article John does a tour of Delta/Rockwell and Powermatic manufacturing facilities and reports on some of the methods used in the production of their machines. He is not afraid to ask some challenging questions and gets some straight forward answers. Older machines were hard to beat, however things have changed over the last four decades. The original owners are long gone and both companies have changed hands many times. The emphasis is on stock profits (and I'll stay away from that rant). Delta is now owned by a Taiwan Co. and Powermatic is now owned by a stock fund co.

John writes about some good maintenance and operating tips for things like a jointer and voices his opinion on his preferences, like me he likes to refurbish older machines when they can be acquired at reasonable prices. Nothing like old iron. lol.
