Looking good.

 

I was worried that you weren't going to finish it when I read your Facebook post.

Where I'm lookig for a machine for sale ?  I was wondering how much could be a used one. The I've got an offer for 1500EUR.... reminds me why I started to build one

Well I don't trust the stiffness of this housing, so I've made a frame instead 

 

And I'm thinking of making another driving hub for the dizzy as this chuck won't hold it securely

 I have problems with the chuck on my proper machine when doing Lucas distributors.

So today I've made a Lucas driving hub, I hope it will be stabile

 

Next I have to figure out the support for the dizzy. I really like what I can see on old Bosch machines : iz looks pretty reliable

I found that too (though my own machine doesn't have a chuck). You might be better off making a Drive Dog for fitting in the Chuck to drive the Lucas units.

Good news : it's working 

 

Bad news : I can't see it 

 

First thought was that the opening for the light is too narrow, but it's more like because I placed the LED on its side therefore it is not strong enough to see it

 

I think I should paint the disc to matt black for more contrast.

 

And I've eplaced the driving hub for a felxible CNC coupling.

Today I've made the support arm for the dizzy. It is pretty stable. 

 

The slip ring became the weak point of the machine. Originally I choosed a small one which fits tightly to the 8mm shaft but its thin and solid wires  can brake easily

 

Next I will install a bigger one for which I can solder thicker wires.

 

The test shows that there is something wrong my 25D dizzy : it's rattle as it rotates but I don't know the reason

 

I also fixed a 45D and it works more silently.

 

To be continued....

That is usually worn holes in the advance weights and or the spring is loose (fix the holes first). The distributor will usually rattle if shaken.

When they get really bad they wear into the housing at full advance.

I've removed the base plate and turned the dizzy on different rpm's but I can not see the weights moving. It should visible?

 

How can I fix the holes ?  

 

One spring should be loose, isn't it ?

 

On the 45D there are different weights, I see as they "fly"  out or in.

Yes you should be able to see the weights come out but they will be a blur due to the speed. Manually play with the weights and advance to see what is happening. See if the weights are loose by moving them with your finger, there shouldn't be much movement. They work the same as the 45D but are just a bit different shape.

 

For steel weights I find good ones.

 

In most cases one spring should be loose but there is at least one mini distributor specification which has two identical springs.

I still have some issues, any advice would be helpful

 

I've connected my multimeter to check the accuracy of the machine. As you can see it shows 56 degrees but the arc length is far from that value

 

The given dwell in the specification is for crank or cam degrees ?

 

For the light I bought cheap chinese LED's but all of them killed    It is possible that these LED's can not resists for the many on-off switching ?

 

 

 

 

Another issue that the arc lenght stretches with RPM

 

Here is two short video
