jukejoint Posted April 27, 2015 Share Posted April 27, 2015 so ive been trying to figure out how to make my hook with a lag bolt thread any ideas ? Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted April 27, 2015 Share Posted April 27, 2015 Buy it at the Hardware Store. Cheapest.If you have make it yourself, forge the threaded end, tapered square with sharp corners. To thread it, heat it evenly, quench the tip you are going to grab and use your Twisting Wrench to twist it COUNTER CLOCK-WISE quickly. Twisting this way will make a clock-wise thread.Neil Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted April 27, 2015 Share Posted April 27, 2015 WHY??? Because IME a tapered spike on a J hook will hold tighter than a lag bolt in solid wood! I have NEVER had one pull out under load! PERFECT performance is very difficult to improve upon!!! Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted April 27, 2015 Share Posted April 27, 2015 (edited) Forge it from a lag bolt that is UNPLATED Edited April 27, 2015 by ThomasPowers Quote Link to comment Share on other sites More sharing options...
jason0 Posted May 1, 2015 Share Posted May 1, 2015 Hello,Wouldn't the twisting method make the metal prone to breakage?I know how to cut machine screws with taps/dies, and have even done it on a lathe in my youth. How do you cut wood screws? Are there dies for that?I would be happy with straight screws such as those on lagg bolts...but I am also curious about tapered screws too.Thanks for your time!--jason Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted May 1, 2015 Share Posted May 1, 2015 No, the twisting process shouldn't affect the metal strength... if done wrongly or to extreme it could though. A tapered, hand forged nail or spike though is, IME, several times as hard to withdraw in wood as a similar sized screw of modern manufacture. They are more comparable to ring-shanked nails in my opinion! Further if even MORE holding power is desired (hard to imagine WHY) then a much easier way of doing it is to nick small barbs along the corners of the tapered, hand-forged, spike or nail! Only places where I might consider doing this is where I might be hanging something weighty in direct line with the fastener shank. Quote Link to comment Share on other sites More sharing options...
anvil Posted May 1, 2015 Share Posted May 1, 2015 To answer your question, I've made some nice hooks out of lag bolts by upsetting the head forge welding on whatever I need to make the hook. Quote Link to comment Share on other sites More sharing options...
HWooldridge Posted May 1, 2015 Share Posted May 1, 2015 (edited) Peter Ross at Colonial Williamsburg had some antique dies that were impressed to make lag screw threads in one hit. The work was forged to an approximate taper then placed in the dies and finished with one swat. I'm sure a little bit of flash occurred but probably not enough to worry about with regard to function and the period smiths may have employed a "grunt" to finish the threads by filing.I'd bet someone could use a modern lag to create the dies then have something to make hooks and such.
