Push a square inner cap into the ends of the press base and attach a 3 1/2 - pulley to each of the two brackets on the weight base.
Use carriage bolts to attach the press base to the weight base with nylon locknuts, but do not tighten them yet. Attach the lower end of the butterfly upright to the butterfly base with carriage bolts, but do not tighten the locknuts yet. Push caps into the butterfly top frame and attach it to the butterfly upright.
Bolt the butterfly seat frame and front leg together. Bolt the front leg to the butterfly base and the butterfly seat frame to the butterfly upright. Push caps into the top of the front leg and each end of the small leg lever. Attach the bumper to the front of the front leg with a tap screw. Attach the small leg lever to the bracket on the front leg with a lubricated bolt and nylon jamnut that allows it to pivot freely.
Attach the bench press upright to the press base and bolt the support frame to both the press base and the upright but do not tighten the locknuts yet. Push a square inner cap into the end of the press top frame then bolt it onto the top of the bench press upright. Push a square inner cap into the end of the press seat frame and then bolt it to the press base and press upright but do not tighten it yet. Attach the leg press lever to the press base with a lubricated bolt and locknut.
Place weight bumpers over both holes in the left end of the weight base and slide a weight guide bar into each hole. Attach with bolts, washers and locknuts. Slide six weights onto the weight guides with the pin grooves on the bottom. Push a weight tube bumper into the bottom of the short weight tube and push it through the center hole of the weight. Slide a top weight on the top. Repeat this step with the holes on the right end of the weight base, but use 10 weights and the long weight tube.
