I've been asked what I've done to create a flat bottom on the Ovale V8 units I have. While it is not my intent to turn dragonbone's thread into a modding thread, I thought I'd also through in a little on the display treatment of the late model version. I will start there.
The display on that V8 sits back quite a bit from where the LED display of the former units did. In order to bring it somewhat forward, at least on the top, I inserted two toothpick behind the display. Thsee were cut short by the nippers seen in the photo.
I additionally blocked out the silver appearing legs and mask the edges of the display for a cleaner look. The tape was further trimmed with scissors from the photo below.
Next is the bottom treatment. Stirps of rubber were cut from a surplus back flap on a gas powered push mower that had seen it's better days (don't through away materials that may have future applications!). 3 ovals, slightly larget than the bottom of the Ovale V8 were cut and the split down the middle where the bottom separates from the V8. Adheseive was applited to the rubber stips, bound with rubber bands and then let to sit overnight.
The next step is to wrap a piece of electrical tape around the bottom of the V. Here some care is needed to set the V8 level and have the tape just touching the level surface on which it is sitting. The upward curving surfaces of the V8 bottom will be recessed away from the bottom surface of the tape. RTV is applied to the area within the tape boundary and it is set upon a paper sufrace to set up. i use deli paper for that ais it does not absorb the moisture from the RTV. RTV is a "Room Temperature Vulcanizing" silicone that sets up in a few hours and is fully cured in 24. In the picture, excess RTV is scraped away from the V8, thought is is not really necessary.
After the RTV is well set, the excess and paper can be cut away from the V8 and the electrical tape removed. Some cutting with a razor knife is necessary to separate the halves of the V8 case after removing the tape. A rotary tool can be used to sluff away the edges rubber strips and RTV where they may extend beyond the body of the V8.. A flat bottom will be formed and the deli paper will still be affixed. I chose to remove the deli paper by placing a piece of sandpaper on a flat horiizontal surface and carfully dragging thee V8 across the sandpaper with moderately firm pressure. It is important to keep the V8 squarely vertical while doing this.
The result will be a flat, relatively firm rubber bottom which will stand erect and stable on a desktop or other horiztonal surface. You should expect some imperfections around the base.
I'm not suggesting that anyone take these improvements on unless they are comfortable with the tools and materails. I just wanted to illustrate how I went about creating a steady V8. Perhaps this presentation can stimulate some similar and maybe easier ones by other users. : )
