I've had a Cameo Silhouette for a few years and it works great.
Pretty much only use it to cut vinyl for sandblasting glass.
I've used the software for scroll saw patterns often.
As for me I use a lot of ML Campbell's precatalyzed Magnamax Lacquer.
I also use a lot of their woodsong stain.
It's acetone based and can be sprayed with Lacquer after just 20 to 30 minutes.
A mix similar to Danish oil would be equal parts of BLO,mineral spirits,and an oil based vanish.
I say equal parts but it can be modified to personal likes,and some people us Naptha or Turpentine as the thinner but I always just used Mineral spirits.
You can also just thin down a varnish for a wipe on finish.
I use a laser printer,I make my patterns in grey and it prints them in grey.
If I use a pattern made by some one else that's black I change it from black to grey in a photo program.
A lot of it sold is B/BB or BB/BB
B is the good side,no plugs,limited pin knots.
BB has more knots and a limited number of plugs
I get 1/8" stuff from Wurth wood group, B/BB for about $17.50 A 5'X5' sheet.
They're over 100 miles away but they deliver in my area twice a week.
There's one in Atlanta.
With nicks all three blades will have the same nick in line.
I had a Dewalt planer years ago and can't remember if you can shift the blades a little but if you can so the nicks don't line up it will help.
If not maybe flip one back around to the other side so it mismatches.
I actually have a tool grinder/sharpener and do all my sharpening in house but I don't mess with those disposable blades,I just replace them.
My guess is it's an Oliver 36"scroll saw
A guy on a site I visit got an old Beach no.1 ceiling mount scroll saw running. http://www.contractortalk.com/f40/beach-no-1-ceiling-mounted-scroll-saw-142822/
