Instead of trying to build one, if you want a leg press machine watch for a gym to close down for a chance to purchase a used one or keep an eye on classified ads in local newspapers or online. It would probably cost more to build a proper one than to buy a new one. A leg press machine is not necessary for a home gym. Instead of leg presses, concentrate on squats. If you master squats, you will not need to bother with leg presses, which are less effective than squats. Use different kinds of squats such as box squats.
