Yup Joey's video series are my favorite but there's a ton of guides out there on how to make different style racks. It's kinda hard to avoid that 5'' of overlap on both ends tho (I say 5'' because with the perpendicular 2x4 supports its 1.5'' + 3.5'') because if you make the stand 10'' longer instead then the tank's trim won't sit on the outer frame. My suggestion would be to use 4x4's instead for the risers/supports (legs), or make it longer with additional supports under the inner frame. Unless you don't mind the stand overlapping the corners of the bottom tanks lol. What are the tank dimensions anyways? All 4ft right? If so then dont forget to factor in the trim if they're glass (48.5'' and 48.25'' in my case). That extra .25'' on the 55 ruined my original design to make it flush with the front because i made the inner bottom frame EXACTLY 48''
