The following is a letter we offer to answer any questions you may have about the current manufacturer of the DeWalt scroll saws:
Seyco Sales
242 National Dr
Rockwall, TX 75032
July 31, 2003
Attention: Mr. Ray Seymore
Dear Ray,
Just thought I would write to you in response to your inquiries.
As of February 2003, Sommerville Design and Mfg. INC. officially
ceased manufacturing the DeWalt DW723 scroll saw and related products.
The production of this saw has moved to the far east in order to capitalize on some cost reduction opportunities, therefore you can appreciate the fact that we have no influence on any future models with respect to quality or features. I am also unable to predict what changes, if any will be instituted.
This is going to allow us to concentrate more time on further developing and refining the "Excalibur" line of products. Specifically we will continue to supply the EX-19 and EX-30 machines with North American made electrical components and local materials whenever possible.
I hope this brings you up to speed on current events and answers
some of your questions.
We are looking forward to the "new" future.
Yours truly,
Tom Sommerville
I AM HAVING A PROBLEM CUTTING THICK HARDWOOD. WHAT AM I DOING WRONG? There are many things that can affect your ability to cut thick hardwoods such as feedrate; aggressiveness of the blade you are using (design, how sharp it is, etc.) However there is one thing we have discovered with most scrollers that we will cover here for your consideration since it seems to be the most common problem. Scrollers are told by virtually all saw manufacturers that their saw has a certain "thickness capacity" that is just not possible with standard scroll saw blades. I think they must be calling the "Clearance" between the table top and the lowest part of the top arm their "thickness capacity". We use the "Maximum Practical Calculated Thickness Capacity" to explain and this seems to clear up most misconceptions. SEE EXAMPLE BELOW:
1. Most all STANDARD 5" blades have a tooth surface area
of approximately 3-1/4".
2. Factor in the fact that usually there is a few teeth (around
1/4 - 1/2" worth) left below the table in the most upward
part of the stroke. Usually this is a fixed amount determined
by the saws designer.
3. Factor in the stroke length of your saw (here we will use 3/4"
which is fairly standard)
4. Add the thickness of the table (we will use 3/8" here)
5. Do the math (add these up) and you can quickly see you have
only 1 -7/8" worth of teeth left AT BEST, making blade positioning
a critical issue, otherwise you could be trying to saw with blade
(on the top side) that has NO TEETH which causes the blade to
"BOW' badly resulting in a curved or "bellied"
cut.
WHICH IS THE CORRECT BLADE TO USE ? ? ?
When it comes to blade selection, there is only one exact criteria
- EXPERIENCE ! You can ask 5 scrollers which blade to use and
you will likely get 5 totally different answers. OUR BEST SUGGESTION
is that you have a variety of blades at your disposal for experimentation.
Try them on your projects in your materials with your saw and
determine which size or type that you are most comfortable with
and you will have your answers with a minimum investment in both
blades and time. SEYCO offers SAMPLER PA KS of blades for your
experimentation. See our catalog or call 1 (800) 462-3353 and
ask our representative for assistance
I HAVE DIFFICULTY "HOLDING DOWN" MY WORKPIECE WHILE
SAWING. WHAT AM I DOING WRONG?
Occasionally this problem is caused by using a blade that is too
large for your project. Usually a smaller size blade lessen this
tendency. The scroll saw design is such that there is a light
tendency for this to happen even with a properly adjusted s aw
since it's cutting action is a reciprocating action. Check the
blade path both side-to-side and front-to-back. Excessive movement
in the action can usually be adjusted out on most saws, if not
call your supplier and explain the problem. They can refer you
to their service center for advise.
