Topic tags/keywords: stock preparation shaper straight straight line ripsaw millwork

Hello everyone first time posting here.
I recently started work in a small production mill work shop (2 man operation), have been in carpentry for almost 20 years, doing custom work out of my own home shop for my customers for the past 5. So my question is if making lets say a siding or flooring product from stock size lumber, using a shaper for cutting 5 1/2” ship lap for example, do you go to the next size bigger stock and prep down to finish size (i have access to a straight line ripsaw in this facility) Problem i ran into today is my boss promised a customer 1×12” tight fitting ship lap from 1×12” stock and frankly iv done everything in my power as far as making shaper fixtures to allow the bent stock to run and achieve an even shoulder width on the cuts, but i pulled the plug after the first 5 pieces (out of 4000lf) i ran and tested the fit on had around 1/4” gap at the middle due to un-prepped stock.

Thanks in advance for any pointers

Not nearly as experienced as you in the carpentry realm, but would like to help with ideas if possible.

First for the sake of good communication, my understanding of the problem statement is:
- You are starting with stock 1×12 lumber, so 0.75×11.25 and need to mill it with a shiplap rabbet on each opposing long side to create shiplap siding retaining the original dimensions.

- You are cutting the rabbets on a shaper without stock prep which has resulted in twists and bows remaining in the final board.

Got two broad thoughts:
- One, 1/4” sounds easy to bang out of the final product with well placed nails and pressure
- Two, do some stock prep to get a more uniform final board
- Two A, thin the board to make it easier to conduct thought number one.

The mill works shops in my area mill from Rough lumber . They also have machines that are capable to do it day in and day out. For example the planer they use has a 6 inch cutting circle with 6 knives. It’s nearly impossible to get within 10 feet with hearing protection.
Good Luck

sounds like they have a shaper like a sawmill i worked in out of high school. lumber went in rough and came out finished all 4 sides. could be t&g could be ship lap could be ??? whatever the order called for. loud as heck and kicked out some serious footage.

Have your say...
