Description:
Used for centers and chucks https://www.kbctools.com/itemdetail/1-820-401

FYI.?
When used it only a coating do not pack chuck. Just use a soldering brush on the geat teeth. I little is all you need.

Dave?

Here a white lead sub for dead centers and bevel gears in scroll chucks. (Do use on scroll side of chuck 5w or 10w)

This a trick works some times
Engaging the haft nuts?
If lead screw is 16 tpi then can Engage with 16 toi , 32 tpi and 48 tpi without the thread dial.
A 1.5tpm lead screw? you can engage without a thread dial 1.5 and .75
A 2 TPM lead screw can be engage without a dial 2, 1 and .5.

This works great on lathes with 4TPI lead screw. 4, 8, 12, 16, 20, 24, 30, 32, 36 and 40 tpi.? Lathe I used for 30 years had a 4TPI. Almost never had to use a thread dial.??

??? ??? Thank you sir

I've had the bars, 10mm internal and 10mm external and their inserts for a few (or several) years, and had to look around a bit.? ?Nothing on the packaging.

Found the chart below on amazon.? ?I have the 11ER-A60 and 11IR-A60 inserts - 16 to 48 tpi.

??? For me it's much easier to see whats going on when running out of the hole with the cutter on the back side of the hole upside down . SO what is the insert yer using ? What is the range of threads it can cut ?

??? ??? thanks

If you are working on parts for antique machines, then yes they used all kinds of add threads and you’d never be able to find taps and dies for them all. But any new parts are likely to be metric and there are so few standard metric sizes you could own every die.

Yes, running out the the hole is an excellent technique.? ?Useful to an external thread to a shoulder also, but the blind hole under power .... really necessary.

I have done a lot of single point threading but because I did not have a tap or die in that size.
I never had a choice.?

If doing blind R/H threading use reverse and start the thread inside so tool bit is outside when finished?

A36 steel use high rake for better finish?

The images are of 1/2x20tpi threads - with no discernable play and smooth turning.? ?The male threads are on 3/4" brass rod and the nut is gold iridite (yellow chromate?) finish grade 8.

It's the beginning of a drain spud for a furnace humidifier.? ?It is since drilled through 0.280" and has a 3/4" male 45 degree taper seat on the left side.? ?Does it need to be that good?? ?No, but I want it that good.? ?After all, it's a hobby!

There are some Ni based rods that do a reasonable job of color matching cast iron. Success is helped with experience - find a welder who's done it repeatedly.

Us mere mortals are more likely to be successful with brazing. All the caveats about slow temperature changes & doing small areas at a time still apply

I found someone interested a color match is a real pain. It is surprising of different colors in cast iron.?

I like brazing too it does great job and can done with almost sun glasses and a torch. I still have 100 pounds of rod for cast iron work.?

This is project I plan to do for a long time

A flame eater engine aka candle eater engine.
See file section for complete set of drawings?

After I sold my business I work as Repair Machinist.? You see a lot of attempts at cast iron repair.? JB weld was one best to see , you had take time to remove all JB from casting. This same for bad welds and brazing.? Mainly it add hours to job.?
This includes strip tap holes everthing they try fail.?

That would include welding , brazing and plug {drill and tap for crank cases not thread inserts} and must be done right the first time.

This Old Tony has a video about this??

I use both?
I like brazing over using cast iron rod?
But cast iron rod is closer match.?
