dimple die questions?

[300sniper]

there has been quite a few threads on dimple dies lately that have got me thinking about making a set for myself. i know it will take a long time and not be worth it money wise but i need the time and practice on my lathe.

does the depth of the dimple increase as the diameter does? i was looking at the pictures of the dimples made by GOAT1 on this thread :http://www.pirate4x4.com/forum/showthread.php?t=516640&highlight=dimple+dies and would guess the actual angle part of the die is around .250 deep. the die used for that was a 1". does any one have an actual measurement for the depth of dimple vs. the diameter of the hole?

I was thinking the same thing. Those sets are pricey. hardened 1010 or 4140? Are there any standards for dimpled/flared holes? maybe aircraft ind? All we need are some dimensions can anyone help?:D

Blase made some, he has some info in his "neverending build" thread http://www.pirate4x4.com/forum/showthread.php?t=539098

He does some sick machine work.

well i went ahead and made a 1" set. i just used 2" round bar mild steel because that is what i had around. this was an experiment anyways so i will use something harder now that i know i can do it. after they came off the lathe i gave them a black oxide finish for the "tool" look.

when i was done i found out that i don't even have a 1" hole saw:p . i used a unibit to drill the hole but it was about 1-1/16" diameter. this made the flare a bit off of center. i don't have a press yet so i used an old greenlee knock out set ratchet to squeeze the two parts together. this worked perfect with a 3/4" hole in the dies.

this is 16 gauge sheet:

i am confident that if the hole was 1" the flare would be centered.

Nice work Sniper...You made/built a 1" dimple die but don't have a press or 1" hole saw :laughing: Kinda reverse order don't ya think?

I like the blackoxide finish, I don't think Blase hardened his either and they worked fine.

BTW, HF has their 12T press~$109 and 20Tpress ~$179 on sale right now...

the press? i definatly plan on making a single post one for dimple dies. a similar idea but different than yours. do you think you could take a few measurements from your dies? it would be greatly appreciated:beer::beer:

[Butler]

surely, shirley. Which dimensions and which dies?

[MT4Runner]

I was wondering about using an old bearing center race and the back part of an old D44 front spindle to make a ~1.75" dimple die??

[300sniper]

surely, shirley. Which dimensions and which dies?

basically i am looking for the angle of the male and female die. i thought i read some where that the male was a 45* and the female was a 40* but i can't find that information again to save my life. also the length of the angle on both the male and female for the different sizes. i have no idea if the length of the angle is longer for larger diameter dies. if the length is the same for all the dies i guess only one would need to be measured. i hope this makes sense.

thanks.

just get some pig as lug nuts for semi trucks, drill a hole and use a press to flare it out. did it a lot and it's for like a 1/2 or 3/4in hole and cost me all or nada to do.

[guidolyons]

Xteror1- Necessity is the mother of invention! Ghetto or not, it looks like it worked pretty well.

[Arya Ebrahimi]

Question: Does using dimple dies noticeably increase the ID of the hole? i.e. you drill a 1" hole to start with, what is the ID after being dimpled?

[TITANS]

If you get a set of dies the inside hole does not change size. if you ghetto some holes then yes they might.

[Xteror1]

This is only going to be used as an engine and trans skid. So looks aren't important. With no press the dies would be useless:flipoff2: . I was more interested in if it would work with 3/16 steel.

That's pretty impressive if that's 3/16". Half of you bitches with your $$$ dimple die sets calling his method ghetto can't dimple 3/16", esp in that hole size. :flipoff2:

mostly because there is no reason to dimple over 1/8" thick, from what i have read.

[rokdog03]

Jmr dimple dies can dimple .125 4130 and 3/16 mild steel.

Back to the point please can someone provide some insight here?

WRONG

I have a set of Light Racing dies. If you dimple a peice with a 3/4" die. A peice of 1" tubing will fit in the hole after its flared. It gets bigger after it gets flared.

thanks for helping with the hijack issue:D
i'm still waiting for some numbers.

[Wicked_S10]

Any measurements yet? I am looking at picking up a small lathe pretty soon, and this is going to be one of my first projects :)

Later,

Weight...

[300sniper]

Weight...

cutting holes in the material to save weight may still be needed over 1/8" but i think the dimple is not effective at over that thickness, again, from what i have read.

Looks good!

The 45 and 40 are good for steel (plain/4130). You could go steeper (60/65) and still release. Aluminum sheet can use a steeper dies. Need to look up coefficient of friction of the material, use that number for arc-sine to get the "critical angle". More than that angle parts will NOT release, less than that angle they are self releasing.

Machinist trick on why C5 and R8 use those angles for collets. :) Self releasing and self locking.

Another thing you'll want to look for is KASENIT. Old compounds were arsenic, thankfully hasn't be used in ages. Just a matter of getting your steel dies up to a nice red hot temp, dropping in the compound. It will harden the surface. Google Kasenit (I think that is the trade name, Casenite was the common name... sigh, getting old and forgetting stuff sucks)

Any dimensions on your dimple die sniper?

[Butler]

Sorry, sniper I've been caught up in some stuff lately. I will get the dim's tonight I promise.:(

[Butler]

ok, I have a 1.5" and a 1". The minor diameter on both males is a few thousandths under the full die diameter. A few under 1.5" and 1" respectively. The base of the flare on the 1" male is about 1.475 and the 1.5" is 2.260 give or take. There is no clear change of the plane into the flare so I came as close as possible. The depth of the flare on the 1' is about .248 and the 1.5" is about .350. The base of the flare in the female 1" is about 1.475 and the 1.5" is about 2.175. The inner diameters of both female parts are exactly the callout dimension. Does this help?

I bought a set of Light Racing dimple dies, now if I can just find some dial calipers, I'd be happy to measure them for everyone.

AryThose are measurements from light racing dies. ;) I can get you measurements from a 3/4" and a 2" as well, just let me know.

the 2" dimensions would be great. thanks for the others. sounds like i was real close to what they have with my 1". i think i am mostly wondering if the depth of the dimple gets larger as the diameter does.

thanks again.
