As I have posted thinking of turning some white oak one inch thick into
3/4 inch lumber for a bed.
Thinking of buying a small tabletop planer maybe Delta. May also buy a
jointer if I can find money.
How long will the blades last in each of these machines for this
Are they easily replaceable? Expensive? Will I have to change them very
I have a Delta 22-580 planer and a 6" Jet jointer. Generally, I change the
planer blades about 4-5 times a year. The blades are disposable and double
sided. Average yearly cost is for blades $60 to $90 and the planer is used
quite often as I buy all lumber in the rough. The blades are easy to change,
the machine has indexing pins that the blades are just set on. The 22-580
is a great machine! I've shoved 3" thick by 12" wide oak lumber through it,
and it does fine.
The Jet 6" jointer will be replaced as soon as I can afford to.
Although it's also been a fine machine, I have outgrown it. Blades are not
disposable and run around $25 to $50 per set depending on brand name. I
generally go through about three sets a year. However, I recently bought a
tormek and am going to start sharpening the used blades, so the future cost
should be minimal. The blades are not as easy to set up on most jointers.
There are no indexing pins on most models, yet the blades need to be
installed with precision. I bought a magnetic jig ("jointer pal" IIRC) to
install the blades and it has made the task much easier.
In either case, you shouldn't have to change the blades for at least a
few projects in either machine (depending on the size of the project, and
the wood used, etc.) Good luck --dave
I use a 12 1/2'' Delta planer 22-560 (now called TP305) and I am very
satisfied of it. The blades are disposable. The cost is 40$ (can.) for a
reversible set of blades ( $ per set). They are very easy to replace. Most
of the time, I use it for planing hardwood. I don't use it very often so the
price for blades is not an important factor for me.
I don't think it is very expensive but if you plan to be a big user,
consider a planner with blades who can be sharpened. With two sets of blades
you can use your tool while the other set of blades is in sharpening.
You can keep the blades for a long time but quality of the work will
decrease. Sometimes, I use old blades for rough planing and new ones for
finishing. But very used blades are not recommended because the motor have
to work harder.
It is not easy to tell the life of the blades. It depend of the type of
wood, the width, the number of nodes (and nails!) and the way you use it.
For example, if you place your wood at a different place in your planer
every time, the blades will last longer (repartition of usure). If you
remove loose node, you will avoid mark on the blade. Wood with dirty bark on
the sides can cause damage to the blade etc.
