OM Nearing Completion

With its new owner due to visit in a couple of weeks, I've been spending a lot of time lately preparing this guitar for finish.

Here's a shot taken this afternoon after shooting a couple of seal coats of 2lb-cut de-waxed white shellac. Prior to spraying, I inflated a couple of party balloons inside the body of the guitar to seal off the soundhole and the soundport, preventing any contamination of the interior.

Given my limited experience with sprayed finishes, it's a case of "so far, so good". I arrived at what I think was the right combination of spray gun settings more by trial and error than anything else. Setting the correct air pressure at the compressor, then adjusting spray pattern, air flow and material flow at the gun took some patience but, as with anything unfamiliar, the secret lies in constant practice.

Without a dust-free environment to work in my finishes are never going to be flawless but, under the circumstances, I'm pretty happy with the results so far. My hope is that the top coats of KTM-SV are as easy to apply as the shellac seal coats were. I guess I'll find out over the next few days!

Cheers
Pete
