Here's how to make your own Bow Press, to be used quickly and without fuss, which is why you need to use it in the first place...
It is constructed from two sizes of square profile, about 2" square in cross cut, chosen so that the sizes can telescope within one another. It makes possible to change the press size, and thus, adapt it for all compound bow lengths. One long spindle, made out of industrial screw material uses one or two winged nuts to fix the bowlimb rollers at proper distance.
When the roller distance has been determined and fixed, the bow is laid with limb backs symmetrically set into the roller grooves covered with deerskin laps. Rollers do not need to be clad in deerskin all the way, since they do not rotate full circle. Make sure rollers touch the limbs in their midst, or maybe one inch outwards, meaning closer to cams, or a cam & idler wheel.
Two strong gurt or rope 'circles' are laid over the riser at both ends, so that the overlapping pieces form two loops hanging from the bow. Both loops at each riser end are then connected to the hooks that extend from the pedal lever. In the same time, the pedal lever is shifted along the lower horizontal profile so that the bow's arrow tray hangs about vertically over the point where hooks connect to the pedal lever. This will make the forces bending the limbs equal on both riser sides.
Step on the pedal to push, and thus, pull the riser downward: via pedal lever / hooks / riser gurts... and while pressing , carefully move the pedal around and under the locking bolt. Move the pedal lever all the way under the bolt and carefully release it. With the bow limbs pressed, bowstring and cable(s) should be limp , and all the string, cam and wheel parts become accessible and removable. Repair and / or adjust what requires your attention. Check the wheel axles fo looseness, and grooved parts of the cable and bowstring serving for wear. Remove dust and grime, caked mud and / or blood, grass, seeds, hair etcetera. Add oil if required. Repair serving. Have a glass of <____enter favorite drink here_____> yourself, don't just work. We have a saying that boldly states: "Work is not a rabbit. It'll wait."
Make sure all string material is in their correct grooves and all the other parts are reconnected as they should be. There shouldn't be any familiar-looking bow parts on the desk or on the floor around you, before pressing upon the pedal to release the*pressure and re-establish the bow. To be on the safe side, before releasing the pedal, tension the bowstring a little by pulling it upwards. That'll force strings and things into their respective places. Presto! There's your bow, repaired or adjusted, and off the press in a matter of seconds.
The press weighs some twenty pounds, not more, and it can be taken along with a group of compound shooting archers with no extra trouble. It is cleanly designed, easy to mantain and operate, and quicker than many other; quicker to use than most of the portable hand presses, while this one holds your bow in the proper servicing position. The press itself can be taken apart for transport or storage in a matter of seconds! Just screw the wing nut off the spindle screw, and slide two halves of the construction apart. The pedal lever slides off the separated construct with no effort and no tools, since it's not really affixed to anything. Study the sketch, and you'll want to make one of those, I'm certain.
