Does anyone have a thread chaser for a 1926 cowl gas tank? Mine has some hardened POR 15 on the lower threads making it difficult to screw the gas cap on, all the way. Jim Patrick
A small cut off wheel on a Dremal will help. Drain tank first, and fill with water,then chase threads,drain out water and flush with some acetone,drain and add gas back.
You can also drag a smaller tap around the inside of the opening. As long as it is the same threads per inch it will clean it up with a little work.
You can drag a smaller faucet inside the opening.
Where are these spammers coming from? Seems that they have been getting more "popular" lately. Dave
I just watched keith rucker on vintage machinery use a new tool called ez thread, think it might work well for dremel. Use a 60% angle diamond wheel. KGB
Richard's suggestion is one that I've used many many times. Works good. Just need a little patience.
Here is another thread chaser
He's nuts about her!
All that to find out she has a left hand thread. Think about it.
Didn't have to think long!
