I am new to wood working so thank you in advance!
My friend and I are creating small, machined, wood products from pre-dried wood. Although we treat them with tung or linseed oil after machining/sanding, the components tend to crack after some time sitting in an indoor environment. I am looking for somewhat of a consultant to help me finalize a process that prevents cracking of various woods we used. I'm happy to pay for an expert to provide detailed explanations. Thank you in advance!
CURRENT PROCESS
1. We use pre-dried woods (10% - 12% MC)
2. Wood is stored in a semi warm/humid environment (60% - 88% relative humidity)
3. Wood is machined (cnc and manual machines) in this environment
4. semi-finished parts are stored in this environment
5. Parts are sanded and treated with tung or linseed oil
6. finished product then shipped to customers. They are generally stored indoors (15% - 40% RH)
QUESTIONS:
1. Best way to seal wood from expanding/contracting in low RH environments (absolute best way methods)
2. tips for machining
3. tips on storing wood prior to machining
4. tips on storing semi-finished parts (partially machined but untreated)
WOODS USED:
I know different woods have different properties. I am listing the woods below in hopes that someone has expertise with the different woods and can comment/help specifically.
Maple
Koa
purpleheart
zebrawood
sandalwood
bamboo
ebony
rosewood
walnut
bubinga
wenge
