My Father has recently decided he is too old to do workshop type work anymore. At 83 I’ll let him use that excuse. As a result of his decision he has started unloading some of his tools on me. Many have seen better days. Florida’s salt air is hard enough on tools, and much of what he liked to work on were boats, so his tools had a hard life. I’ve decided a few are worth rescuing.
This handscrew clamp had was one of the first in need. For the most part it was still operational, but some of its wood was burned, damaged and worst of all, polyurethaned {GASP}. The polyurethane made it look bad and made the jaws slippery… not a good attribute for a clamp. Please, for safety’s sake, never put a film finish on a handscrew’s jaws. Boiled linseed oil works fine, or just leave them natural and they will grip just fine.
Getting started removing the polyurethane with a card scraper.
Removing polyurethane with a card scraper is a pretty easy job. Fortunately this handscrew only had a couple of coats on it. As it came off along with a wee bit of patina (grime and grunge) a stamp emerged. “Jorgensen” brought a smile to my face. It had a few siblings to hang on the rack with.
Removing the polyurethane from the jaws of the handscrew.
The jaws needed some work. They were badly damaged, rounded and even had burns at the hands of someone clearly using the wrong tool for the job. The tips of the jaws were especially bad.
Holes, breaks, burns, and rounded edges on the business end of this handscrew.
The cleanest repair for this seemed to be amputation of the tips of the jaws. There was plenty of length to them so it seemed they should remain usable even if they lose 3/8″.
With the tips cut off, the jaws become more usable.
After a bit more scraping and cleaning, hear was the end result. One of the handles had some surface damage that made it uncomfortable to use, so in cleaning that up, I turned it into an octagon. I found that the octagon handle made it much more effective than the other, so later turned the other handle into an octagon. The change i s pretty quick with a block plane.
Handscrew repaired and fully usable.
Whether recovered from a polyurethane shell or purchased new, handscrews in a variety of sizes can be of tremendous value in the shop. I use them all the time. I am partial to the Jorgensen as they are well made and made in the USA. I do understand that the Pinnacle brand and Dubuque clamp works brand are also made in the USA but I have no firsthand experience with either of them.
Handscrew Clamps
If you are new to using handscrews, here is some information and inspiration on using them.
Where to find them:

As a full time web developer I need a desk that allows me to work at my computer standing up, but when I need to get off my feet, can also let me sit down. As a picky person I have a long list of requirements Allow me to use the computer while standing up […]
- Brilliant Woodworking Animation – Chair makes itself
This video (really a still frame animation) of making a lawn chair is quite fantastic. I like the style of the chair, but the brilliant bit is the way the craftsman / videographer make it appear as if the wood and tools are making the chair themselves. Clever no matter how you look at it. […]
- Walk the Plank … the Cedar Diving Board.
My son swims quite well for a 4 year old, and when he expressed an interest in diving from a diving board, I wanted to be an encouraging father. So I went out to the shop and rummaged around for a suitable plank. I had 5′ long 2″x6″ made of cedar. It was not quite […]
- Home Depot Choosing China Again
I was in my local Home Depot yesterday and walking through the tool section looking to buy a couple of bar clamps. I have always favored the Jorgensen brand because they are sturdy, well made, and are made in the USA. I have always appreciated that Home Depot carries them. So I walk […]
- Workbench Serendipity Favors … someone else
Every old tool fan has a story of the one that got away. Some great old gem of a tool that slipped through their fingers for some reason or another. My most recent one still makes me shake my head in disbelief. I’m not fully up and running with my new garage bay workshop. To […]
- Good Plane Advice – Good Physics
This video is amazing and clearly shows the effects of a chip breaker with a much steeper angle on the front of it (think snow plow rather than ramp) and setting it closer to the edge of the blade than “conventional wisdom” would have suggested. The video very clearly shows that the chip breaker works […]
- Rustic Outdoor Lamp Posts
My workshop in FL is still not ready yet, so here is one from a collection of things from my time in NY that I had not gotten around to posting. On our property I needed some outdoor lighting to keep our B&B guests from bumping into things in the dark. Any of the modern […]
- Kids Builds at Lowes and Home Depot
While my workshop is being reconfigured, the only real woodworking projects I have been doing lately are taking my 3 yr old to the Home Depot Kids Workshop and the Lowes Build and Grow Workshop a few times a month. Both stores really do a nice thing of providing the kits, tools and work space […]
- No Waste – High Tech Timberframing
I watched this video and was impressed by all the cool automated technology used to create the timberframe components. But I also thought, where’s the fun in that? Industrially precut timber framing has become the predominant house construction method throughout Japan. In this documentary, Bakoko explains the process from factory floor to building site. […]
- Vaughan Hammer – Sad Gloat
I am still suffering from a severe case of workshop withdrawal. The entire contents of my workshop are still residing in a 5’x8’x8′ U-box pod waiting for us to move into a new house. Overall I have to say I am happy with the U-box service…just sad to be without a shop for the duration […]
- Band Saw Set-up Video
I have a Craftsman 14″ bandsaw that is a twin brother to the Rikon (the Rikon has a few more refinements). I am not certain whether Rikon makes the Craftsman or some third company makes both the Rikon and Craftsman. Either way, I saw this video about fine tuning at setup and I wanted to […]
- Barn Moving
In general, timber frame structures are incredibly solid and stable. Here is a great example of the stability when 344 people gathered to lift a barn and move it by hand and foot from one location to another.
- Mallet Head Angle
I’ve seen this issue come up and get discussed on several forums. A joiners mallet is pretty simple to make, so it is a quick and satisfying shop project to get one constructed, but then the question arises, “what angle should be put on the head?” This is an important question with advice ranging from […]
- Tuning Up a Cheap Spokeshave
For years I have been keeping my eye out for a rounded bottom spokeshave (convex, front to back). I have an old Stanley 151M flat soled spokeshave that works quite well and I wanted a vintage round bottom Stanley 151R to match. Unfortunately they seem to be kind of rare, or on eBay the photos […]
- Chisel – Long Lost Brother
Tool owner stamps always intrigue me. When I pick up one of my old wood planes and look at the layers of old owner stamps on them, I wonder who they were and what they did. Were they carpenters, or just hobbyists? Did they pass them on to their children? Did they save up for […]
- Portable Chisel Rack
For years I have kept my chisels in a drawer. I keep covers on the tips so they don’t damage each other, but as my chisel collection has grown, the drawer has gotten crowded and is just not the best way to store and access them repeatedly. So I decided to make a chisel rack. […]
- Old Tools Passed On
I was fortunate to spend several weeks around the holidays soaking up some sun in Florida and spending time with my family. Time with my wife and son on the beach was gift No 1 and brings a smile to my face just thinking about it…especially as I look out the window now at the […]
- Making Chisel Handles
In the last post I showed off some newly made socket chisel handles and justified the use of octagonal shaping on the back section. If you liked the finished product and wanted to see how I made them, then this post is for you. Ideally, if I were some kind of master sculptor I could […]
- Replacement Chisel Handles
I have an odd collection of chisels ranging from a couple of modern plastic handled abominations to several old Stanley 750’s , an old Witherby, a PS&W and a D.R. Barton. I am gradually replacing the plastic handled chisels as I find older socket handled varieties. I like my old chisels, some belonged to my […]
