Belled Hole Boxing Plates

Do you guys remember seeing recently, someone who had welded some patches behind his belled holes in his boxing plates ?? If someone could kindly direct me to the thread or magazine article it would be much appreciated.

 

There's an article in the April 2015 issue of Street Rodder about Hollywood Hot Rods building a ch***is for a '32 coupe that had cups made from 2 1/2" schedule 40 steel pipe caps welded into the dimpled holes in the boxing plates, along with a lot of other "sculpted" parts. Maybe that's what you're thinking of..........................

 

Not sure what you are describing but Dave Shuten did this on the Iron Orchid.

 

Thanks badshifter - That's what I was looking for, however there was a build thread I'm pretty sure that I saw in the last few weeks that showed an unfinished ch***is, and the guy had done this to the boxing plates.

 

Just checked out SR April '15, that's a pretty elaborate set up. What I saw was like the picture above.

 

There seems to be some nomenclature confusion.

I would call those dimpled boxing plates.

I would call these belled/flared hole boxing plates, but others call these dimpled boxing plates.

Everyone has a different term for the same thing, and a different thing for the same term.

 

I recall the thread and looking at it but cannot locate it probably because I didn't post a reply on it.

 

You can't "flair" dimples and
You can't dimple a hole.

 

I Agree, on both counts.... I'm not sure what process was used on the Iron Orchid, however I would say the end product are Dimpled boxing plates. Even though Wolfe's Metal Fab, (where this image is from) calls his Dimpled boxing plates....Ionia Hot Rods calls them Belled hole ???? For me a golf ball is dimpled.

Interesting though, that the tool used is a Dimple Die, Anyone else confused ??

 

I always thought that those holes were to take some weight off the pieces and to fill them from behind to be cute seems to negate the process and add more weight than you started with.

 

they are cool, what ever you call them

 

I'm just confused.

 

With any kind of large holes in the boxing plates, how do you paint the inside of the frame? Or do you just let it rust?

 

Yep,
Having the dimples adds both strength and visual excitement.

 

I would call it Marston Mat cut into strips.

 

Belled holes are for adding strength, which the boxing plates don't actually need. So they are purely for aesthetics any way. Putting a piece of metal the same size as the hole will not add any more weight than before.

That's what my wife says. I just wish I had them....

 

It will if you use 2-1/2" Schedule 40 hemisphere pipe caps

 

since we are discussing names for those. when do the terms chad, hanging chad and fat chad come in?

 

I thought chads were specific to paper punching. Chad is the piece that is punched out, hanging chad is piece that did not separate.

Sheetmetal punching would give a slug, the piece punched out. Slug in metal would be the same as a chad in paper processing.

I worked in both a printing press and metal stamping plants, same operation but has different names.

 

Deluxe 32, consider a punch and ****on to create the recess without punching out the hole. You'll need some tonnage to get it done, good tool top and bottom and an alignment setup, metal thickness clearance in the tool. Punching the holes, adding the bell radius then cutting more material to weld in the back seems like a large amount of work.

 

Since it's "been done" already, is there a reason to copy it? Not directed to anyone in particular, just sayin...

 

To me a dimple is a surface feature like I added for the brakeline in this frame:

A flare and bell are different, the flare gives a little reinforcing/finishing edge to a hole and the bell is more aggressive rolling the edge inboard. The flare is more automotive and the bell is more aircraft. I punched a couple in aluminum so you can see the difference:


The starting hole was the same size for both.

 

Sure,
The holed parts are lighter
The belled parts are stronger
Openings give access.
The dimples are functional, necessary or just cute.

 

31 Vic, I get the obvious. I meant the filling in part. Based on the info shared tho, some dimples just beg to be filled, and again, just sayin...

 

Ignoring rust doesn't work.

 

Oh yeah--there are arrows!

 

I knew I'd find it...
