Tool Question...

If a hand reamer is used to enlarge a hole in a piece of metal, say for a switch or such...

What type of tool is used to reduce a piece of metal evenly by hand that is not a lathe...

Example... I want to reduce the size of the wiper motor shafts to allow me to tap them to accept the acorn nut... The wipers I have are later models from a M-151...

I have used a file, but that takes lots of patience and is not an even removal of metal around the center of the shaft... A die will do it but threads the shaft... I want to remove metal without threading it...

Put you thinking caps on because I cannot think what the tool woould be called...

I get what you are after but I can't say I've ever seen anything of the sort.

Just find some way to mount your wiper motor in a wood lathe or an electric motor of some sort, center the work and use your file as a stationary cutter. I did this in the past before I owned a lathe to smooth out welds on a shaft. Just don't spin it too fast or push too hard as it may fly off. You could probably file off .01 like this pretty quick. The problem is for threads you have a narrow range for your O.D. otherwise you will not have deep enough threads so you better go slow. If you have an existing bolt the wiper nut will screw onto, use that as a reference O.D.

talking about reshapimg metal without a lathe.
The idle mixture adjusting screw in the carburetor had a bad groove cut in it, And I could not lean it out. so I placed the screw head in the drill press. Let the drill press spin the screw and used a jewlers file to reshape the point on the screw. After that I was able to adjust the carburetor.

I know what you are doing and have done mine by hand with a file. I usually tape the line to stop at as a guide. I have put things that need to be reduced in my upright drill press and spun them with it and filed the item. Taking a brand new vacuum wiper motor apart is risky. You probably will ruin the gasket seal doing it. That's why I did mine by hand until I could use the die to thread it. What was cool was the die actually left the angled taper the wiper arm locks down on. John

I have already done my wipers, was just wondering if there was a tool out there that would havemade it easier...

And that is what we took time to provide you.... a thank you would be better than telling us that we didn't answer your question and laughing.

Well, I guess I need to design a tool that will do the job, then I can give the credit to the folks on this forum for letting me know it is needed as it has not been built before....
