Ripping timber

Postby johnfarris » Sun Jun 10, 2018 11:56 am

When I buy my timber in a sawn state I always try to buy as close to the finished size as possible. Machining the timber I take an even amount off both sides . I do this because I have read it prevents defects.

I visited a timber yard on Monday to buy some iroko and they only have the wider boards. Speaking to a yard hand he informs me that it is common practise to rip down the centre as sometimes it springs some time is does not.
I wonder how other people deal with this? I have factored in 30% wastage for the timber

For waney edged boards I believe that the rule of thumb is 100% wastage.

You will always get some tension release. When you split a board down ty centre. It’s always been that way. Just split the board and use the machine to take off any twisting
