Ho no it is very accurate
The cut trait is 0.05mm and very precise
It is the head that need adjustment on most of the machine you can cut from 45dg to 90dg angle. On the Syren the rip are 5mm and the head must be adjust to 90dg precise if the angle is jut 89.5dg you have a distortion that give a slight angle.
My older son is a specialist in cutting aero steel with high pressure sand blasting machine
They cut up to 3inch of high grade steel with tolerance of a maximum on 0.5mm again the head must be adjust with precision otherwise you have an angle and scrap metal.

A question: you mentioned the bearding line. Don't you have to thin down the false keel in that area so that the planking lays flush with the stern post?

Yes I see that Chuck thought about marking it on the false keel, but at the stern the false keel should be no thicker than the stern post otherwise the planking will not lay flush. Most POB modelers suggest tapering the false keel down on each side starting at the line. I think this shows what I mean better than a lot of words. Scroll down to page 4 .

Nice to see you are able to super multi task. I don't doubt you will be passing me shortly. I've got a couple busy weeks at work coming up.

About time

Step 4 Constructions of guns ports and bridge water sweep port

The guns ports are 15/32 '' or 11.5mm
The sweep port are 1/8 '' or 3mm
For practical reasons I decide to build 2 templates that will be used at this time to help the placement of the opening and later when hull planking a rim of 1/32 '' or 0.5mm must be allocated my template has this rim which should make my work easier + later
