Greenfield #8 tap wrench handles

For the record, TRW owned Greenfield Tap & Die for awhile, so it's not uncommon to see old stock labeled as TRW but it was still produced by GTD. I have a die set where some of them are marked as TRW and others GTD. Now they go by the name Widia.

The older GTD tap wrenches seem to have a better finish as at some point they stopped using nickle and just went with black oxide.
 
Doogie, thanks for the bit of info. I will tell you that this #8 tap wrench looks to be identical to all Greenfield #8's I have seen, so you post makes a lot of sense. If this is a "clone" it is a darn good one!
 
If I understand your posts correctly appearance is the sole reason that you want to replace working tool handles?
 
Wreck- I found the perfect Christmas gift for you next year!

Wreck, yup. Then I'll have them powder coated Sunset Fucia with metallic highlights...............................it will go well with the Lime Green I plan to coat the main body with.........although, I am considering earthy pastels in the rest of the shop tooling..............................
 
Besides, Dykum Red and Blue are soooooo retro for the motif I am trying to achieve.........................:p
 
being totally serious, at 12" handle length, they are a wee bit anemic for larger taps.......in addition to being just plain ugly. I was planning to upgrade to 18" handles with will give a 50% increase in torque capabilities with the same force applied (measured in foot pounds) That being said, I also wouldn't mind the handles being in similar condition to the tool head, which is in Very good condition. Hope that answers your question. I guess I could also go with heavy wall tubing instead of solid rod or new black pipe.

What my original question was all about was, since 3/4" black pipe OD is 1.050 and solid rod OD is 1.000, does the missing 0.050 from the major diameter of the thread for 3/4" NPT make that much difference since this is not a pressure fitting and the thread is tapered if I were to use 1.000 OD stock. My question still stands. Whether I use solid rod or heavy wall tubing. I get the weight consideration, and that can be part of the final solution decision. I can either use the stock "as is" (which I have on hand), or I need to buy 1.125 stock, and turn the thread area down to 1.050
 
Stock handles are supposed to make this assembly ~ 40" overall. You want the full diameter so that the handle fully engages the taper of the tap holder without applying pressure to the threads. Use steel so you can even add a cheater when necessary. Aluminum has no place on a tool like this.
