Hi everyone!
Here we are again, doing what we love to do. I hope you get
a kick out of this. I'm going to keep this plain and simple.
Bear with me and I'll show you the hap's...... |
| Here is
the balance card that we have. We needed to figure the oil
weight. We came up with 7.5 grams, to give us a total of 2030 grams for our
bobweight! |
 |
| Here are
the weights that we'll be using to do our balance act!
|
 |
From
left to right (Big-Small) the weights are as follows:
19.5g, 4.5g, 1g, & .25g |
 |
| Here is
the fixture that we'll use, including all the weights that go
with it! |
 |
| Make
sure that you have an equal amount of weight on both sides |
 |
| Make
sure that you include all the parts that go with the bob to get
your weight right. |
 |
| Go ahead
and assemble the bobweights. |
 |
| Here is
our Softface Balancer. |
 |
 |
|
| Here we
have the crank chucked up in the machine to get it ready for
balancing! |
 |
| Bill is
putting on the bobweights that I have made up for "The Poor
Mans 427". |
 |
| Make
sure that you have all the letters the right way. All of these
bobweights are a matched set. You need to line up the letters.
Also you have to have an equal amount of distance from one end
to the other (meaning you have to have equal distance on both
sides of the clamp). If you don't, it'll throw off the
balance and your engine will have a vibration that you
don't want! |
 |
| Next we
are lining up the bobweights to the crank and each other. |
 |
 |
 |
 |
|
| Make
sure that the bobweights have a 90-degree angle from one
another. |
 |
| Here is
where we are to drill a hole in the crank. Like you might guess,
this crank will look like Swiss cheese. Our bobweight is
sooooo much less then the factory! We started drilling after we
spun the crank of course. |
 |
 |
 |
 |
|
| After a
few hours this is what it looks like. It looks like the ugly
duckling! |
 |
 |
|
| Here we
are spinning the crank. If the unbalance part of the scale is 3
or less then you are good to go. But we wanted better then that,
so we are under 1. (Click thumbnail at right for short
video file .mpg file.) |
 |
|
To be that well-balanced, its about a gram
off. This is a gram of weight...that's not much. |
 |
Next we'll show you what we've done to the
block to get it prepped for assembly!
