Saw Rehab – Stanley 26″ Rip Saw

This one is not a refurbish project. It’s simpler, a rehab, if you please. As can be seen by the handle, this is not a priceless antique. It is one that I purchased new at some big orange home center, maybe in the 1980s. It clearly dates to the era when handles sank to their ugliest just before Buck Rogers style plastic handles. The saw has a 26 inch plate and is filed rip, 7 TPI. … and the hang hole in the tip was drilled by the manufacturer, not me.

I once picked this saw up during my earlier boat building days, and just as quickly set it aside. It didn’t cut well and had a noticeable kink about midway along the tooth line. If memory serves, the most previous abuse was cutting sheetrock or some other kind of rock.

Removing the kink

Read enough around the Internet and you’ll think you need a blacksmith’s anvil and planishing hammers to take the kink out of a saw blade. TRY THIS FIRST: I removed the handle, just to make it easier to mount the handle end of the plate in a vise. Once about an inch of the plate was tightly clamped, I curled the saw first one way, then the other. Don’t be bashful. FIRMLY grab the toe end, pull it around toward the handle end. Once you reach a “U” shape, keep on going, running the curl up and down the length of the plate. Repeat a few times to both sides. Like magic, the kink was relieved and smoothed away.

No magic. The teeth were not really in bad shape, just dull. Sighting along the line, I saw that all were even enough to not even warrant a flattening filing. I simple hit each tooth with a couple of swipes of the file and then tested. Tops: 20 minutes.

The first job for this “new again” saw (OK. it really needs to have the plate cleaned) was resawing a length of 1×4 poplar. I was very pleased to find the saw working straight and true, and running easily.

Saw Restoration – Richardson Backsaw

The eBay seller warned that hand saws were not part of her expertise. So, I didn’t ask for details. The photos were good enough to think it worth bidding.

Richardson, later Richardson Brothers, was a saw manufacturer in Newark New Jersey, about 20 miles down the road from where we live. From what I’ve learned, Richardson made highly respected products. They had one of the early patents for taper grinds on full length saws. Long story short, it seems they were also a very strong competitor to Disston. One contention is that around 1890 Disston manged to “do away” with some of its competitors by buying them and throwing them into a conglomerate known as “National Saw” which died in 1906.

This particular saw has a medallion that carries the 1867 patent indication placing it later than that date, and before the company started marking their products with a “Richardson Brothers” brand in the late 1870s. The stamping on the spine is an arched “Richardson” with “Newark NJ” below the arch, “Cast Steel” to the left, and “Warranted” to the right. The blade measures 14 inches long and has a depth under the back of  3 and 3/8 inches. It is 0.029″ thick.

4 photos of the saw as I received itThis saw did not lead as sheltered a life as the Disston #4 I restored a couple of weeks ago. Whoever owned this Richardson used it hard,  probably never sharpened it, and then left it where it gathered a good bit of rust and pitting and lost most of the finish on the handle. The area of the handle where one grips still had a little varnish and several kinds of “donor paint.” The end where it meets the plate was bare, dry, and heavily stained. The upper horn has a bit split off the underside and presents a ragged edge to the web of the hand that holds it. The plate has no dents and is absolutely straight, as is the spine. It was filed 12 TPI, rip, and arrived in my hands with absolutely no set.

4 phots of the restored sawI restored this blade the same way I did the Disston, with a (very long) bath in Evapo-Rust and then lots and lots of sanding. There is still a good bit of pitting and maybe a long session with a belt sander could solve that, but my belt sander has yet to be purchased. I sanded off what little finish remained on the handle and sanded some of the stains away. There’s no need to reshape this handle because it was already of the era when they made them nice and comfortable. As for the split out area on the upper horn, I voted against splicing in a repair and simply carved that area to a new smooth profile. I’m unsure, but think the handle material to be apple which was very prevalent at the time. Finish is 3 coats of clear shellac ending with wax rubbed in with steel wool.

My sharpening required reducing the teeth down to about 50% of their original height before I got a nice row of flat spots to work from. Then I sharpened the toe end with relaxed rake for a couple of inches with the rest sharpened at near zero rake, all on the original 12 TPI. I now have two very nice back saws and might opt for a third for smaller dovetail work.

Bring It a Little Closer

In a comment on the post about refurbishing the Disston saw, Ralph mentioned he had trouble focusing on things that small. I’m not sure whether “focus” meant a real vision problem, or interest that wanders away. If a vision problem, this might help…

photo of block and lampI’m shamelessly stealing the idea from Megan Fitzpatrick who recently wrote about updating her bench. She included pictures of how a ubiquitous magnifying lamp was adapted for use on the workbench. The lamp stands on a column 1/2 inch in diameter. My bench as a whole bunch of 3/4 inch holes for holdfasts. I took a block of scrap 2 by something. drilled a 1/2″ hole all the way through, flipped it over and drilled a 3/4″ hole most of the way through, and glued a 3/4″ piece of dowel in that hole. Now, I can locate that magnifying lamp almost anywhere.

Saw Restoration – Disston D4

It’s time to do something about a woefully inadequate saw collection. Other than my shopmade frame saw and shopmade turning saw, my other saws are modern disposables that probably wouldn’t be good enough for a rough carpentry contractor.

Mass production of western style handsaws started a nose dive in the middle of the last century and have brought us to cheap, colorful, plastic handled blister raisers with brittle teeth that can’t be sharpened. Yes, there are a few premium western saw makers currently making superb saws. If those are your fancy, a good Google search will find many of them for you. For myself, I like refurbishing older tools. So, it was off to eBay to find my first goal, a small back saw suitable for fine joinery.

photos of Disston Nbr 4 sawThis Disston Nbr. 4 is has a 10 inch blade, has a plate depth of 2.5 inches under the back, plate thickness of 0.031″, is filed for 12 teeth per inch rip, and has a steel back. The blocky, semi-ugly beech handle dates it to after 1940. There’s no stamping on the back (also after 1940), and the etch on the plate dates it to the post WW II era.  Disston was sold in 1956, placing that as the most recent date possible for this saw. This saw had a very easy life. It was barely used and apparently kept in a comfortable place. The handle seems to have original factory finish, with no chips or other damage, not even significant scratches, but some runs. There’s a little bit of donor paint and other stains. The blade has minor rust, a bit of pitting, and “patina.” The teeth are still relatively sharp. The tooth line has an ever so slight bow. The spine has no visible bowing. Before I did anything with it, I tried a few test cuts and found it maybe 20% slower than the spectacular yellow and black Stanley utility saw.

photo of clenaed up bladeSince it is neither rare nor collectable, and screams won’t be heard if I don’t leave it “pristine,” I intend to refurbish it in the manner pursued by Andy “Brit.” That means a very shiny plate. After disassembling, the first stop was in an Evapo-Rust bath. This is the very first “eco friendly” clean-up product that actually has the strength to do what it advertises. Mild rust was gone quickly. Then it’s off to the polishing. I used garnet paper starting at about 250 grit, then wet-n-dry to 600, followed by Abralon sanding pads to 4000. The purists will be upset with losing part of the etch, but it’s a “user” not a collector’s item. That slight bow was removed by clamping the saw in my really simple “saw vise” just above the tooth line and then tapping along the spine with moderate hammer blows buffered by an oak block.

photo of handle restylingThe handle is actually beyond semi-ugly. It is downright ugly and uncomfortable too. It wants some serious reshaping. Any self-respecting saw handle would like to look the part, and I wanted to soften some hard lines, and have a finish that did not includes the runs and curtains of the original poor manufacture. Search around and you’ll see that classic handles had a nib on the top, a lamb’s tongue on the bottom, and curves that actually flowed nicely. Out came my marker, turning saw, a few gouges and a couple of rasps. Reshaping it was so much fun that I lost track of time, maybe and hour or two. Finish is three coats of shellac followed by paste wax applied with steel wool. Satin s-m-o-o-o-o-o-o-t-h! The brass finished up relatively quickly with the Abralon pads followed by rottenstone in wax and buffing.

photos of completed sawLastly, comes sharpening. I’m constantly amazed at how many people think saw sharpening some mysterious art. I see it as a fundamental skill for anyone working with hand tools. Why send something out to be sharpened? Why bear the expense and delay. (Some of those premium saw makers offer sharpening services, but have backlogs measured in weeks and months.) Learning to sharpen a saw is something that can be accomplished in only a couple of hours and is a lifetime skill that improves whenever you use it. Once you know how, you can sharpen a saw in less time than it takes to stand in line at the post office. Learn here, or if you’re a member of Paul Seller’s Woodworking Masterclasses online school, learn here. Also, be aware that rip filings do cross cutting surprisingly well, so you can do a lot with the simplest filing technique. I used Seller’s advice and filed the first dozen teeth at the toe of this saw with 10-12 degrees of rake. The next dozen teeth were filed at 5-8 degrees of rake, and all the rest at zero degrees of rake. The idea is to use the toe for easy starting and to have aggressive rake for the remainder of the blade. Time: about 20 minutes. The saw arrived with quite a lot of set. Some disappeared in the filing, but a noticeable amount remained. Test cuts now make this saw about 20% faster than the spectacular yellow and black Stanley utility saw. It cuts rip very smoothly and cross cut slightly less smoothly, but acceptably fast. It’s faster in hardwood than in softwood, indicating I need just a little more set. … tomorrow’s improvement.

All done, I’ve sharpened some skills, saved an old saw from a trip to the land fill, gained what I consider a premium saw, and did it for about 1/10th the cost of a new premium saw.

Just wait til you see the next one…

Carving on a Turned Object – #2 – Lathe Enhancement

Sometimes, there’s madness in my method. Back when I made the adjustable tool rest, I used a certain shape in anticipation of these carvings.

51+w65WS2cL._SL500_AA300_Inspiration for this pair of turnings comes from yet another Frederick Wilbur book, “Carving Architectural Details in Wood: The Classical Tradition.” A little rosette appears in the lower corners of a very ornate picture frame. It’s a classic rosette that’s frequently seen on period furnishings. Besides its appeal to me, it is sometimes carved from a turned base, one of the reasons I built a lathe.

photo of drawing and book images

As with many carvings, I like to draw the item a couple of times myself. It helps be get a better feel for the object, for knowing the turning profile, and for having a fair idea of how to create the result.

photo of steps in tutning the baseThe turnings are of walnut. Because the dominant features are on the face, these need to be mounted for faceplate turning. I used a small “Easy Wood Tools” faceplate, to which I screwed some sacrificial pine. To that, the walnut is attached by the technique of gluing a layer of paper between the pine and walnut.

The turning is straightforward. Walnut works very easily. The only unusual aspect is that I have not yet made a tool rest specifically for faceplate turning. So, I improvised by F-clamping the existing tool rest across the lathe’s ways in the only way it would fit … backwards.

photo of 4 steps of carving and completing the rosettesAt my level of ability, carving is about two factors, grain and sequence. Feeling grain interaction with tools is almost second nature now. The real consideration for grain on these pieces was orientation with respect to features. I decided to place the leaves between the pedals on diagonals to the grain direction. My hope was in minimizing the likelihood of breakage. That worked out great. Sequence is the other aspect that I find challenging. What to cut first? My instinct was to set in the spaces between pedals first, and to do that with cuts that minimize the pressure on what will be the sharp ridge of the leaves. That worked out OK. The rest of the carving was to remove everything else that’s neither leaf nor pedal. :-)

photo of enhanced tool restLastly, I drilled the back of each rosette with a 3/4″ hole the depth of a metal nut, and additional 1/4″ hole to accommodate a screw. The nut is set in a pool of epoxy. The whiteness of the epoxy is due to a filler.

Finish: simple boiled linseed oil.  NO sanding harmed either this carving or me!

The result is… some classy knobs to replace the ugly wing nuts on the adjustable tool rest!

Carving on a Turned Object – #2 – WIP

Work in Progress. Just one photo for now.
