3/8" is on the small side, but it's an option. Thanks

I have a furniture project that requires two 3 foot long pieces of rebar to be heated pounded/textured and bent into perfect half circles. I don’t have a forge (I know, I should fix that), but I do have an acetylene torch. Do you think I could accomplish the even bending portion of the task by just heating the rod with the torch?

Don’t want to break up the morris discussion but it turns out that Frosty’s initial advice was best. I made a guess at 28 tpi but once I got a more comprehensive thread gauge, it turns out it’s 24. 

It turns out that 1/2-24 tpi is even more uncommon than 28 tpi. Have not been able to find an of-the-shelf thread adaptor option to go from 1/2-24 to anything normal ( except for guns, but they have a hole in the middle). So, do I look for a local machine shop, or is there a known company on the internet where I can order one. 

Thanks for the suggestions guys. Do you think this drill has been modified, can’t imagine that 1/2-28 thread was a thing 100 years ago.

Thanks for reading my post Larry, and especially for expanding a few joules of brain energy to come up with your suggestion. Barring someone else’s better solution I think I will go with your suggestion, it should work.

Hi ya’ll I’m new here. Heard somewhere that some of the post drill gurus live here, so I’m hoping you can help me. I recently came into a Champion Forge post drill, I think it’s a No. 110. It came with a 100 year old Westinghouse ac motor. It didn’t come with a chuck at all, and I’d like to put a Jacobs chuck on it. The real problem is that the spindle ends in a 1/2 “ threaded shaft with a crazy fine thread. It’s not 1/2-20, it might be 28 tpi.  I didn’t know there was such a thing. Anyway I don’t know what to do with it, I haven’t seen a Jacobs chuck with more than a 20 tpi thread. I’m going to try attach pics. Any help will be appreciated.
