Creating a radius form tool

[@samueltaylor4989]

You should make a rubber sleeve for the Norbide stick. Or rubber hose shoved over it, just the end sticking out. That way if you drop it, the worst case is the end chips off but won’t break in half.

It was the 1960 all over again for this 20 man Bridgeport/5 Boyer Schultz injection mold shop apprentice. Mostly forming wheels to grind hardened A6 or S7 tool steel concave with matching convex corners, each with the shrinkage factor included. Our grinding room had a cabinet containing about 18 spare hubs retaining the old male or female radii dressed forms. Sometimes a bit worn but a good starting point to redress instead of paring down a new wheel.

Now we're back to "The Grind"!! I learn the most from your grinding project videos, & this one is no exception- Thanks Stan!

[@DudleyToolwright]

No rest for the wicked. Nice video, Stan. You know, it is because of your first video, that I went and found this type of dresser.

[@bearsrodshop7067]

Diaomite Stan, wgen you and Phil stopped in back in March, my Pexto 617 bead roller was by tge front door. I have need more dies, and thx for taking the time to share. I see now, why my big dies are so costly $$ .👍👍

Very informative video Stan. The wheel profile jig is such an amazing tool. Grinding a lathe tool like this would be so difficult any other way. Cheers Nobby

[@garyreisdorf1363]

Stan, Very Informative. When chatter occurs with a form tool, shift the lathe into neutral, dial in .001 add lots of cutting oil and rotate the chuck two turn by hand using a wrench on the chuck jaws. Continue this to finish diameter. It will scrape to completion without chatter marks.

Great video Stan, thanks for taking us along!

HNY…great discussion/demostration/build….thanks for sharing

[@dauber1828]

Stan, you did one cardinal sin Per Robin Never drag parts on your magnetic vise Always lift up Please keep up your great videos Thank you for sharing and have a happy new year

[@chucksmalfus9623]

I actually cringed when he slid the vice across the mag chuck, the scraping sound was terrifying. Stan is still the master !!!

[@mattwa33186]

I have not heard the Rodeo Song in a really long time :)

[@AmateurRedneckWorkshop]

Certainly a cool tool. Thanks for the video keep on keeping on.

[@edsmachine93]

Nice work, thanks for sharing the process. 👍 Have a great day.

[@johncollier7744]

Just subscribed to your channel after leaving a certain Florida based machinist who I think has lost his way. ( I think the YT algorithm pointed me towards your channel) Was great to watch a video that got back to basics and used good old-fashioned hand machinists techniques. Found the entire process interesting and informative. Great video presentation.

[@ShadonHKW]

Thanks John, you will find this channel a mix of field work and shop jobs. Hope you enjoy.

[@MicksWorkshop]

Excellent video Stan. I learn so much from your videos.

[@RyanWeishalla]

I still use the form tool you made for me from time time for inside radii. It also gives me the best finish on brass when I made a few brass hammer handles.

[@richardmills5450]

That was really good. You have a lot of excellent content on your channel Cheers

[@ShadonHKW]

Welcome to the channel, always a mixed bag, enjoy.

[@bcbloc02]

Form tools have a ton of pressure so for sure they are chatter monsters.

[@markspann5813]

Very helpful video, Stan. I also have that dresser. Hope you have a great and happy New Year!

[@swanvalleymachineshop]

Good one Stan . My Jung HF50 has a Diaform wheel dresser on it for wheel profiling like that . There are a couple of small parts missing , but one day i will get it sorted ! Have a great New Year . 👍

[@kimber1958]

Thank you Stan.GREAT VIDEO. Have a safe new year

[@RRINTHESHOP]

Nice job Stan. I did not catch what material you used for the die. Were you going to heat treat?

[@ShadonHKW]

Its 4140, It will get mid 50's, but letting him try it first, thanks for the view & comment Randy, happy new year!

[@sharkrivermachine]

I like it! Happy New Year!

[@Rustinox]

Good one, Stan. I thought the thing would chatter way more than it actually did. So, that's good :)

[@CraigLYoung]

Thanks for sharing and Happy New Year to you and your family 😅

[@Ron_EZ]

18:04 Stan is that a staple in your finger, did you catch the business end of a tool? 🤔

[@machinists-shortcuts]

For safety tilt the tool in the direction of the wheel so it can't grab into the wheel. Or cut the radius in the toolbit with a carbide cutter.

[@chrisstephens6673]

I too would go for making the form with a carbide end mill, I have some tapered multi fluted mills that can put in relief as they cut.

[@ThePottingShedWorkshop]

Yes, it gave me the jitters thinking what would happen if the toolbit slipped in the vise!

[@machinists-shortcuts]

@@ThePottingShedWorkshop always safer to pivot the part downwards if it grabs rather than pivoting up into the wheel.

[@floridaflywheelersantiquee7578]

Nice video thanks for sharing

[@williamfissell1694]

Stan, I see you have the tool leaning into the wheel. If for any reason your vise loosened or the HSS got trapped, it would interfere between the mag chuck and the wheel. Any reason you didnt have it facing the other way?

[@ShadonHKW]

Just the same as sharpening a knife blade, you roll the wire edge up onto the blade other than out beyond the cutting edge. I was confident in my vice's holding power, if it failed it would have made some interesting video.

[@rkalle66]

With 1/2 inch radius half circle your tool has an working area of 3.14*.5" ... 1.57" beeing a chatter monster and the tool flanks don't have support. Maybe a quarter circle tool is easier to handle.

[@ApukEldar]

👍👍

[@LoomisRex]

what happened to your fingers ?
