Model T Ford Forum: Forum 2015: Homemade Coilbox Lid

I had some fun this week building a lid for my coil box. I believe the originals were deep drawn. I bent this one around a maple form and brazed the corners. The first try was too small. Then I read 14's were slightly tapered. Some dimensions were mentioned on the forum. The second try was too small also but the third one will work. The latch top was fairly easy to form on some dies made from plate and bar. Slots were a series of holes and connected with a hacksaw blade.

There are many ways to enjoy the old cars. I'm glad there are those who enjoy seeing the work as I do.
Charley, I have the box. Thanks for the offer.
I sure can appreciate the folks who make repro parts. The demands to make parts acceptable at a profit and the marketing is way beyond me. It is pretty nice to be able to do this for fun.

Rich

I know a little bit about sheet metal. That being said....you Sir are a true craftsmen...Excellent work! Those "rounded top" coilbox lids are hard to come by.

Richard,

Can you walk through the steps of making the latch top? They look great and I would like to understand the process.

Thanks!

Chris

Charlie, if you scrap them let me know where they go. !o)

Chris, I start with a slotted plate, a guide plate and a plate with the pressing bar. They are held in place with screws and the sheet metal clamped in place. Then I push them together with a 12 ton press. A vise or large c-clamp might work instead.



Next, I trim the blank close to shape traced from a cardboard template. It is sandwiched between a turned cylinder and a horseshoe and clamped in a vise. (the cardboard template is shown rather than a blank.) Then it is hammered to shape. It takes a little practice to learn how hard to pound.





If I were making more than a couple, I would do the last step in some forms like the first step. There is some additional additional shaping to sharpen the curvature but this is the basic idea.

Rich

Charlie Shaver,
Is you tooling for the coil box, lid, or both? I have been wanting to try to make one or more box and lid for a 1914. I would be interested in seeing how you make them. I live about an hour drive from you, near Springfield, MO.

Rich,

Thanks very much for your explanation. Just one other question:

In the last of you original photos you show a "tongue" shaped piece of flat steel and a flat washer. What were these used for?

Chris


Top of pagePrevious messageNext messageBottom of page Link to this message  By Richard Eagle Ida Fls on Saturday, November 14, 2015 - 10:41 am:

It is nice to hear your comments. Thanks.

I left a little extra material on the piece when I shaped it over the cylinder. I placed the tongue shaped piece in the formed latch top and file material down til the file is on the tongue. Then it fits the lid flush and to the right depth. I used the washer the same way but the tongue works better.

An additional tongue piece, not previously show, was made to better shape the top of the formed curvature. Initial pressing left a slope that was not what was needed.



It was a lucky guess on how much clearance to give between the slot and the pressing bar in the first procedure. Too little clearance and it tries to shear the material. Too much and you get a lot of slope. I could have used some large pins in the 3 plates rather than the small screws. This might have resulted in more of a shear at the curvature. It is a little thin there as it is. I think the reshaping afterwards worked better. Also, I am using scrap sheet metal I have. There are special steels that are more suited for this type of work.

OMG you actually MADE the latch tops! VERY nice work! Top itself looks great too!

I remember being in grade school and having a book called 101 Elephant jokes.
One of the jokes was "How do you make a statue of an elephant?'
The answer was "You get a big block of marble and chisel away anything that doesn't look like an elephant"
Richard has done this with the same mentality.
In other words you just do it.
Great job!
