I needed a way to scale up a recent small project, so made these proportional dividers. The pictures are self-explanatory I think. These are simple and relatively easy to make using this simple method for layout. This method works for any sized dividers you may need – i.e., ratio or overall length.
My project needed to be scaled up by 25% (1.25:1), so the dividers are laid out for that ratio. But, since it is easy to do, I went ahead and made holes for 2:1 and 3:1 ratios too – just in case I ever need those in the future. To my eye, curves always look better than straight, so those are thrown in too. The one thing to remember is both end points and any ratio points in between should all be kept in line for the dividers to work accurately.
The detail photo shows all component parts, i.e., mahogany divider legs (mirrored), #8×24TPI x 3/4” brass plated decorative bolt, #8 nylon washer (used between the legs), #8 flat washer and #8×24TPI knurled nut.
