As a bunch of you know, I’ve recently acquired a CNC Router from Oliver Industries.

Here’s a quick tip on getting a really detailed carving with very little tear out.

I’ve been hired to create a couple dozen plaques for a Marathon in my area and although I chose Poplar, which is a fantastic wood to use, the tiny fonts were giving me fits as the wood would chip out between the tiny letters.

I found, quite by accident, that treating the wood with a sealer (in my case spray lacquer) gives a HUGE difference as far as tear out goes!

Here’s a sample of what I mean:

The letters at the top of this piece are only 5mm high and really close together. With a single coat of lacquer I was able to accomplish this level of detail!

An added bonus is that you get a tad more contrast if you don’t treat the piece after carving.

Just thought this would help!

BTW, if anyone would have any more tips like this, PLEASE share them with me!!!!

Appreciative in advance,

-bob

As a almost owner of a CNC… I thank you for the tip… I expect to have my new machine in place in a few months time… so everything I can add to my knowledge now will reduce the very steep learning curve…I too will appreciate any further tips over members can post…

Good tip – thanks!
We just purchased a CNC – it was delivered yesterday and as soon as we get the remodel in the shop finished we’ll be setting up for work. Glad to know this.
