Strip flush on the form?

Submitted by SSpencer on Tue, 06/02/2020 - 19:22

I am building a Petrel Play and fitting the sheer strip.  First, as you can see from the picture, the strip is not laying flush against the form (the last form before the stern inner stem).  I am using glue (not staples) and want to know if this looks right.  Do some of you bevel the forms to accomodate this?  Second, I am dry fitting the sheer strin using notched jigs  to hold them to the forms at the sheer line.  The strip bows out a little in between some of the forms.  Is it more important to make tight contact with each form or to get a fair curve by allowing the strip to slightly move away from some of the forms?  (I hope this second question makes sense)

Thank you.strip on form

Yes, that looks right.

The strips 'on the sides of the boat' will only fully contact a few forms/molds near the middle of the boat.

That's why it's important  to line up the 'contact side' of the form/mold on the station line when you set up the forms...not set all the forms  'facing in the same direction' relative to the line.

It's also important not to try to force the strip to contact the full thickness of the form. With staples, it's pretty easy to just pull out the strip a bit, if you over-drive the staple.

Do some of you bevel the forms to accommodate this? 

I don't and wouldn't. 

The strip bows out a little in between some of the forms.  Is it more important to make tight contact with each form or to get a fair curve by allowing the strip to slightly move away from some of the forms? 

Release the strips so that they are only touching the edge  of the mold that's on the station line and they should assume a fair curve.
