T: step 2 is to put into practice! Plinth1. drilling the base in the desired position to bring the excavators is linked to the base unit.2. use a screw threaded discharge to go to excavators to the base.The arm section.1. using the bolts fastening the joints area.2. Enter the hydraulic system to the leaf-cutting.Part of the lap1. the wood jig saw comes with saw Baltimore Plaza to the wood with a curved, concave.2. wood sawing and then splice together, look at the lap of then connected with glue elephant.3. part of the lap join arms with bolts and glue.A: step 3 is to check the work piece from the 1st piece of work practices. Make a water leak caused the beams area because the degree is not valid. No. 2 From the edit section beams with experimental results. No. 3 Practice and perfection can be bug fixes.T: the results! In parts of the base and the arm from 1st practice found that materials used in assembling the parts it makes us so we found a bug fix so that the results meet what we thought at the beginning. The part of the tripod from 1st practice found that the materials used that device not appropriate areas using the stand attaches to the base. Cause the problem is there is no strength. Finally, you can control the base to fasten the tube injection to provide ease of use.A: (summary) on experimental model of soil hydraulic excavator works as expected. And found that the car can't be digging, lifting of heavy lifting and heavy pressure a lot and Greens coming back of arm digging vehicle. Suitable for lifting with less weight.T: 1. suggestions while cutting wood or use a drill should be placed in the care of a parent or teacher. 2. choose a size to suit the injection tube workpiece. 3. should not slap the area, joints, spinal screws firmly, too. In order to allow the joint toA: 4. should select light wood and light weight, easy to cut, assemble the workpiece. 5. should calculate the distance of the various pieces, piece of work.
