Roybeard Passmore Posted February 23, 2013 Share Posted February 23, 2013 The title is pretty much self explanatory. I've been try to find an old screw swage, but I'm not having much luck. Can anyone point me in the right direction? Quote Link to comment Share on other sites More sharing options...
781 Posted February 23, 2013 Share Posted February 23, 2013 One of the Wood Wright books described how to make a cutter to make wood screws. I dnt believe you can swage wood Quote Link to comment Share on other sites More sharing options...

bigfootnampa Posted February 23, 2013 Share Posted February 23, 2013 They are so rare that if you want one you'll likely have to make your own! We had a thread on one here quite recently... maybe you can use the pics from that for reference? That is the only one I have ever even seen a picture of.

Rich Hale Posted February 23, 2013 Share Posted February 23, 2013 Or did you mean you wish to forge metal wood screws? Quote Link to comment Share on other sites More sharing options...

Roybeard Passmore Posted February 24, 2013 Author Share Posted February 24, 2013 Sorry y'all. Auto correct got me. I meant a metal screw for fastening wood together. And thanks for the replies. This forum has been a lot of help for me starting my little smithy Quote Link to comment Share on other sites More sharing options...
David Einhorn Posted February 24, 2013 Share Posted February 24, 2013 Since we don't know what your exact application is we can only guess at the type of wood screw you are aiming for. With that in mind have you considered taking unplated lag screws and reforging the heads to be more decorative? Some examples include: http://www.tetoniron.com/Hardwarelags.html https://www.blacksmithsdepot.com/page.php?theLocation=/Resources/Product/hardware.xml http://www.blacksmithbolt.com/ Quote Link to comment Share on other sites More sharing options...
Maillemaker Posted February 25, 2013 Share Posted February 25, 2013 http://video.pbs.org/video/1772044886 About ten minutes from the end is an excellent explanation/demonstration by Peter Ross as to how a thread swedge is used. http://www.pbs.org/woodwrightsshop/video/3200/3205.html At 20:11 Roy Underhill shows how a threadcutting plane is used to make wooden threads.

doc Posted February 25, 2013 Share Posted February 25, 2013 I don't see how one of those are used by one man unless you do it while the blank is still in a lathe? Since it tapers, and you would have to hold on to the swage with one hand and tighten it with the other to compensate for this taper. And it should be possible to forge a blank and dress it with a file, but then what do you do if you have no lathe or it is too off center for a lathe? Did they always turn these blanks back in the day? If you go to the link given by BOB S you may be able to understand. The blank can either be filed to shape or done in the lathe. If filed and no lathe is available the rod can be held in a vise while turning the handle and tightening the clamp screw at the same time. Also compare the difference between the swadged screw and the filed screw. The filed one has a taper and point,the swaged one has a flat end with much less taper. Wood screws with flat ends are used as one of the initial markers when first trying to date artifacts that are assembled with wood screws. Hope this helps, DOC Quote Link to comment Share on other sites More sharing options...
silkhopesmith Posted February 25, 2013 Share Posted February 25, 2013 the "thread swedge" as mentioned is a threading die for making machine screw thread, not wood screws. Wood screws have unequal lands and grooves, with better quality examples having much wider grooves and very thin lands. This leaves most wood in the hole intact and more between each land. These split dies do about half their work by swaging and half by cutting. They do produce chips! Quote Link to comment Share on other sites More sharing options...

silkhopesmith Posted February 25, 2013 Share Posted February 25, 2013 Sorry for the confusion, my earlier post I was referring only to Sam's photo of the Butterfield die stock as being for machine screws. I'm still digesting the linked thread posted by Bob S. Quote Link to comment Share on other sites More sharing options...
Roybeard Passmore Posted February 27, 2013 Author Share Posted February 27, 2013 Thanks to everybody for the replies. David Einhorn, I had thought about that, but I would rather make my own. I know it's easier to get some pre-made at the hardware store, but it's not near as fun. And unless I'm making something that's gonna need a lot of screws, it would probably be cheaper and faster to make them than it would be driving to town to buy a couple.

bigfootnampa Posted February 27, 2013 Share Posted February 27, 2013 That Peter Ross video is GREAT... but Roy Underhill needs to find some OTHER place to stand! I applaud Peter's patience... AWESOME! I would have had to ask Roy to GET OFF MY BACK! Amazing that Peter could actually DO anything with such non-stop distraction!

Jeff Lodge Posted February 28, 2013 Share Posted February 28, 2013 If you watch all the Woodwright programs when Roy is with a Smith he is always in the way. I watched one the other night when Roy was at the Anderson Forge in Williamsburg w/ Peter Ross and Roy kept getting in the way there too. I think it just has to do with Roy and his qwerkie nature.
