        <![CDATA[<p>I picked up this <a href="http://www.owwm.com/mfgindex/detail.aspx?id=252">DeWalt</a> <a href="http://en.wikipedia.org/wiki/Radial_arm_saw">Radial Arm Saw</a> (RAS) for about $50 from a nice older man in southern Massachusettes.  It was his father&#8217;s and had been in his family since it was purchased new in 1960.</p>


	<p>Here is a picture of it &#8220;in the wild&#8221;  ( as I found it).</p>


	<p><img src="http://www.rousell.org/images/owwm/dewalt_925/before.jpg" title="as I found it" alt="as I found it" /></p>


	<p>I took it home and began cleaning it up, lubricating moving parts, and then gave it a nice coat of hammered  enamel paint.  I constructed a &#8220;Mr. Sawdust&#8221; style table for it and calibrated all of the alignments.  The blade guard is actually one I  found from a different saw that I like more because it is rear exit for the sawdust&#8230; I also found the matching base cabinet when I picked up a twin parts machine for next to nothing.  Heck the parts machine is also very restorable&#8230;</p>


	<p>The motor  purrs,  and with a new thin kerf negative hook blade from Freud it slices through wood like butter.  Quiet, smooth, precise, and solid! There is something so nice about solidly-built and  well-engineered  american machines from this era.</p>

	<p>Someone asked for step-by-step.. so here goes&#8230;</p>


	<p><strong>Stey-by-Step</strong></p>


	<p>First  some valuable resources:</p>


	<p>TIPS ON DeWalt RADIAL ARM SAW RECONDITIONING (<a href="http://http://woodcentral.com/bparticles/dewaltrebuild.pdf">http://http://woodcentral.com/bparticles/dewaltrebuild.pdf</a>)</p>


	<p><a href="http://wiki.owwm.com/ow.asp?BasicMachineRestoration">Basic Machine Restoration</a> (from OWWM.com)</p>


	<p><strong>Step 1 Examine what you have</strong><br />The wiring looked good, the motor ran smoothly, most moving parts were pretty stiff or not moveable&#8230;  The motor ran ok so I then started loosening stuck parts.. Most important is the ability for it to slide back and forth smoothly on the cast iron machined &#8220;ways&#8221; that the roller bearings glide on.  I was able to get that rolling pretty smoothly with some WD-40 and some adjusting.  Once I knew that the ways were in good shape I committed to a total restore&#8230;</p>


	<p><strong>Step 2: Tear-Down</strong><br />I   disassembled most of the major parts and lubricated parts that needed it, cleaned up dirt, rust where it needed it and broke it down enough to paint.  I did not need to go down   as far as you might for some restorations; I just went far enough to paint on this one.   ON some you might need to get the motor pulled apart and work on the brake or the bearings etc&#8230;</p>


	<p><strong>Step 3: Make it Pretty (Paint)</strong><br />I like the <a href="http://www.masterchem.com/pages/default.aspx?NavID=44">hammered enamel paints from Hammerite</a>.  They are more popular in the UK than they are here but it is great paint.  A truly wonderful finish, and no need to prime&#8230; heck I have seen it go over rust even and do a great job.  I chose their light blue for this job.</p>


	<p><strong>Step 4: The Table -A solid Base is Important</strong><br />A RAS is only as good as the table  you place your  work on.  ( think about how important that cast iron top is to your table saw&#8230;)<br />I built a &#8220;<a href="http://www.mrsawdust.com/">Mr. Sawdust</a>&#8221; table&#8230; which consists of sandwiched MDF with metal bars epoxied in for reinforcement.  Makes a rock solid table!  I added threaded inserts on the underside of the table so that I could use some machine bolts to raise and lower the different sides of the table during the calibration step.  I highly suggest this&#8212;makes adjustment go smoothly.</p>


	<p><strong>Step 5: Reassemble &#38; Calibrate</strong><br />Sometimes I take pictures as I go along with tear-downs- so that I remember how it all goes back together :).  You can also usually get manuals and diagrams from places like www.owwm.com (GREAT resource).  There are several good resources out there for calibration of a DeWalt RAS.  Don’t rush this phase- it takes time but it is really worth it to make it work as precisely as you need it to.</p>


	<p><strong>Step 6:  Let er Rip&#8230; umm well .. Let er Crosscut</strong><br />I am not a believer in ripping with a RAS&#8212;I find a Table Saw works better and safer for that.  Crosscutting and  crosscut Dado operations are where a RAS shines in my opinion.  To make the RAS safer I suggest that you use a blade with a<a href="http://en.wikipedia.org/wiki/Radial_arm_saw#Safety"> negative hook angle</a>.  <a href="http://www.freudtools.com/p-20-thin-kerf-sliding-compound-miterbr-nbsp.aspx">Freud makes some great ones</a> that are available with a thin kerf (which lets you get even more out of these smaller motors&#8230; ) They also make <a href="http://www.freudtools.com/p-315-pro-dado-set.aspx">dado stack sets with a negative hook</a> which is a GREAT fit for a RAS.</p>
