Add Multiple Records To Same Table From Subform

I've only started using Access 2010 since the beginning of January and have googled almost every problem to date.

My db is used to show the status of material through a manufacturing process. We start with one slab of material which gets cut up in to many parts.

The db works so far however I've come to the conclusion that the date was not normalized correctly. So I've created the following tables to fix this.

I have two tables the first of which holds data on the slab we start with and the second shows the status of the parts it has been cut up into.

Table 1 has the following fields

Cast Number
P/O
UST Status
UST Comment

Table 2 has the following fields

Cast Number
Blade ID (which will be 1 to 32)
Status
Comment

I would like table one to be displayed on a form with all fields. Have table two as a subform on the main form. But here is where I get lost!

I need the subform to show 32 text boxes to represent each part. Have each box assigned a default blade ID (1 to 32). Then depending which of the 32 text boxes get used to update those multiple records within Table 2.

I did have 32 status fields for every part but realized that meany were left null. I'm using, Access 2010 with Win 7...
