Default Lamps for a restaurant

Hi all, I did three prototypes of a oil lamp holder for a new restaurant, the choiced one is what I will show here.
It will be produced in a amount of 30-40 but I will not do this production, I just do the design and work procedure for the next company who will do the production.

With the production in my head I need to think much how the toolings can be done, how the metal will move in a stamping process and so on..

Ok , here we go!



First out is the chanels for a wire, the wrinkles appears when I lift the end to start a circle of the piece, I just bend/ lift it to a given amount to not loose the control of the piece!



..then I use my shrinker to keep it the way I like it, then back to the beadroller and lift it slight more, kind of back and forth use of the both machines.



Here is pretty much what I can do with this combo. Now its time to prebend the wire!






..as you can see I use a ringroller, it can be done around anything slight smaller than the size you shoot for as well.

I bended it to a much smaller diameter than it will be and the reason for that is that I get some help from the wire to make my circular piece later.



Here I close the wire edge with my beadroller, the same wheels is used all the way.



This pic show how nice the sheet wrap the wire.



Then I used the sliproller to close the circle, no pressure, just light and easy!



..time to solder the joint, this will not be done in the production.



...and here is a check of the fit around the glassbody of the oil lamp.





..some details need to be done, the piece with the two holes will be part of the wall holder. It will be riveted to the wire edged ring.

..and the "keyhole" is made with use of punches in diffrent sizes, this hole is for hang it up.



The "shield" is embossed with to steps created with the beadroller.



And here is the setup I used, this machines is for slow and delicate work, my first choice is my electric ones but sometimes this one shines



Here is the pieces ready to be attached, I rivet one joint and tinsoldering the others.



..before that I did some dimples for the look and this is what I used, a rivet squeezer.



This is the final product.

In the production simple press dies be used to get a exact result and ofcourse to speed up the work.

Hope to inspire with this and it can be done with only handtools, even if it will take more time.

I know that this can be done in many other ways and this was the quickest way in my shop with the equipment I regulary use.

I really perfer this kind of work before car and bike related stuff, its fun and quick and I have done this kind of prototype work for many years and find it very interesting to do design and production in one package

Have a nice weekend!

Thanks Per for the step by step. I love the steering wheel on your jenny. A bit of an expensive option but very cool.

Thanks Steve, I think part of my clean way to work is related to all stainless steel production I do and always have done.
To work with SS means clean tools, clean benches,clean machines and so on and I think I just do it that way whatever material I work with
A scratch or grinding the wrong way means .....scrapbin.... And that will be pretty expensive

Thanks Kerry, Peter and Dan!

It is always interesting to designing stuff, and even more interesting when I need to calculate how to produce the things in real life, in the frame of the actual budget

Next interesting step in this progress is to design and test tooling for the production, here it need to be simple and relative cheap becouse the low amount of pices.
Here I also need to calculate how " good " the toolings need to be to last.

I do this very oldschool without any computer work, just plain and simple engineering
