New at woodworking... How would I extend these bartop arcade plans?

[jLid]

The bartop accommodates to be 20" wide -- which I assume will fit up to a 20" monitor, correct? If I simply add an inch to all 20" cuts to make for 21" will it fit a 21" monitor? Or 22" to be safe? Or am I reading these plans wrong. This may seem like a newbie question but I am new to woodworking. Started construction class a few days ago in HS.

I will be using a widescreen monitor facing horizontally, not vertically. Would I simply flip the 20" measurements with 22.75"?

Actually from the screen dimensions shown (11.25" x 15") that is cut for a 19" 4:3 monitor. ( FYI == Using the Pythagorean theorem you would have learned in HS the diagonal of the screen would fit a^2 + b^2 = C^2 or 11.25^ + 15^2 = approx 19^2 so the bezel is cut for a 4:3 format 19" diagonal monitor) What type of monitor are you planning on using ? (widescreen 16:9, 16:10 or 4:3) and how big of a bezel does the monitor have if leaving it in the case ?? (as that will make a difference in the dimensions needed.)

Mainly to adjust you would need to know what the dimensions of the monitor are and adjust the width and possibly height of the cab so that the monitor would fit. If using a widescreen then it may be adjusted by just increasing all of the 20" cuts (width of the interior) but if using a 4:3 monitor it might also need the height adjusted which would mean adjusting the dimensions of the side panels as well.

It is a 20" widescreen (my mistake) and it is about an inch bezel. 16:9. I figured since it's widescreen and not a square figure, I could just extend the measurements. I feel like it would fit, but barely.

Looking at the 2009Wfp which is also a widescreen 20" it shows the overall dimensions as 13.14" H x 18.62" W.

So it might just fit in the plan as is ( figure current plan has the screen size as 11.25 x 15 - so that would leave a 5" border (2.5" on each side of the width) so there is enough room barely to fit the 18.62" with about 1" - 1 1/2" border on each side - but that wouldn't leave much room for bezel art so you might want to add a couple inches to the 20" dimensions to make all of the interior pieces 22" rather than 20" ( SO all 3 of the left side panels become 22 rather than 20 wide using an extra 6 inches of the layout (looks like there is 6" there to use) - Then also adjust the monitor cutout to fit the dimensions of your screen.

Should fit since 22x3=66 +21 for the side panel = 87" of the 96" piece leaving the 9" on the right side for the overlap of the second side which looks like it should fit. KInd of like the attached pic ( Note : pic is for example only and not exactly to scale but layoout should fit with interior pieces adjusted to 22" )

If your monitor is the same dimensions as the one JD mentioned you should be fine adding an inch to the width. The key areas where it would get more complicated are the sides and how they are attached to the front and rear panels.

When it doubt... you can always trim it down but adding is a whole different ballgame.

Just looked at a chart that listed the screen size of various aspect ratios and for 20" monitors it listed :

20"  16:9  17.4" x 9.8"
20" 16:10 17.0" 10.6"
20"  4:3   16.0" 12.0"

So since you are using a 20" 16:9 or 16:10 monitor you should be fine without adjusting the original plans -- All you would need to adjust is the size of the monitor cutout in the Bezel to make it smaller vertically ( down from 11.25" to either 9.8" or 10.6") and larger vertically ( up from 15" to either 17.4" or 17") depending on your monitor being either 16:9 or 16:10. Either way it will fit in the 20" width leaving just over 1 - 1 1/2 inches on each side of the bezel. and actually leaving a bit more space on the vertical portion.
