Home made taps qustion

Will the homemade tap works on Brass or any kind metial?

Balsaman and kong made their own ACME taps and used them on derlin plastic and acetal but not brass. Come to think of it I never seen one made in brass by homemade ACME tap. Good question.

I dont know where those two smilies came from. Sorry

ezland,

Well, sort of. It's slow and I didn't go very far when I tried it. Also I'm not sure how long the cold rolled steel would hold up.
When I made my tap I tapered it in my drill press with a file. Then I cut two grooves in it on my tablesaw with a composition metal cutting blade.
I don't think that the geometry of the flutes is perfect and you could do better with some careful Dremel/grinder work. Also you could probably harden it somewhat with heat treatment and a quench.
There are some relatively inexpensive acme taps from _Wholesale Tool that would work better or be less work to get it right.

punch "case hardening home foundry" into a search engine. I know I have seen it on some HF website but can't remember with one.

Packrat, if you are about where the came from, don't :frown: I would that there is nothing with what you wrote. I have an that seems but is worth a : It must be the smilies code on this forum.

I don't think adding that crap on this site is appropiate. That is aimed at Hobbiest post with the crap link.

Relax, Al, I was just demonstrating what can happen by accident if your post contains some "secret code"

Oops, I see your message was directed elsewhere. Maybe he meant angelfire?

Many thanks HU, my blood pressure was going thru the roof.

Re: the tapping question: it is tough enough to cut threads in brass with a commercial tap. Brass seems soft up until you try to cut it with a dull tool, then for some reason it seems as hard as glass

Splurge and buy yourself a real acme tap. Wear it on a chain around your neck and thank your wife for the necklace

You should have seen the look on my wife's face when I gave her a necklace of used up CBN inserts. I thought, "heck these are just as hard as diamond" and I hate to throw them away. But, I never even got to first base, thankless woman!

Huh? So sorry...but at two in the morning I find it hard to think of links, thats why it was a "crap" search, and not a "crap link". Take a pill dude.

Hobbiest, since your post was edited, did you actualy click on the link you gave, or do you not realize it was a link to dirty porn?!
Don't mean to argue, just making sure!
