April 4, 20206 yr "What's It" Basic Rules Reminder For a full run down on this project and rules please go to: "The Patriot Woodworker and MWTCA "What's It" project" Only Patriot Woodworker Members are eligible to participate and receive the award. The MWTCA only accepts a verified source to support your answer, so one should be submitted with your answer, such as a patent, catalog entry, tool book reference, or a respectable website on the subject. Do not let these requirements prevent you from having fun and submitting educated answers on the subject without verification, we can worry about references later. All answers are welcome, as well as healthy debates regarding "What's It". If a verified and referenced answer is not arrived at by the end of each month's "What's It" project, a random draw will be performed for a "One Year MWTCA Club Membership". Only Patriot Woodworker's who participate in this "What's It" topic will be included in the random draw. Additional What's It Rules Unless you are completely sure what this item is, please avoid "definitive statements" that appear that you are without a doubt claiming that you know what the item is. For example stating, "this item is called a "widget xx" used for "insert purpose here". If you are making a definitive statement you must accompany your statement with evidence or proof from a secondary source. An example of acceptable statements within the realm of having fun and educated guesses would be something like this, "I believe it could be", or "It appears it's made for this or that", etc etc etc... Ok ladies and gentlemen, we now have our "What's it" live and ready! The image(s) below is a MWTCA "What's It" image for you to research, and tell us all here in this topic post, just what the heck is it!

April 5, 20206 yr Popular Post 9 hours ago, Gerald said: but what is the cup end for? Some were made to accept a two piece insert that would do a smaller size. The insert fit into the groove visible in the top photo. There should be a notch about center that I can't quite see, that keeps the inserts from spinning in the groove. There was a set of these in the shop that I was told dated from the 1920's-30's. That would have been the Nash era for our plant, and way before my time. I don't remember seeing a brand name on them.

April 5, 20206 yr Author Man I just don't see it. So exactly how does this 'thread chaser' thing a ma jig work? I've seen hand held thread chasers before and typically they are only one thread cutter or two, or three, not the multiple threads you see in this example, that would be very hard to plow through specially with those very short handles, hardly any leverage at all. Now threading machines for threading pipe have rows of threads to cut and clean as it goes, but hand held thread chasers to re-groove threads, typically one cutter or just a few. Just think about it, with the tool you see above, you'd have to clamp the tool down on all threads at once, and with damaged threads, how lucky are you going to be to hit all the threads correctly?

John, They weren't the easiest thing to use. They actually worked better for reforming the end of pipe that was slightly out of round. In that use you had to get one side to align with the threads, and hope it didn't damage the threads further when you closed the handles. You had to get it started from the end threads for chasing the threads. I much preferred using a hand die myself. If I remember correctly the largest size these would handle was 1", with inserts for smaller sized pipe. Some of these early tools were a good idea that weren't really practical in use.

April 7, 20206 yr For those that question, think of it as being able to go around a pipe or threaded rod. Back in the old days it would slowly straighten out the threads, not cut them but bend soft steel back into undamaged shape after cutting the rod or pipe.
