Hello MZH:
My memory of what I did wrong on the Okamoto move has improved a bit.
When you load the grinder on the truck bed with a forklift the grinder is placed on two 4x4 wood standoffs to allow the forks to slide out. It is difficult to nail the 4x4's to the truck bed. My solution involved nailing a stack of 2x4's one on top of the other to obtain sufficient height to prevent the grinder from sliding off the 4x4's This arrangement does not holdup well on a rough road or a sudden stop. That is why I recommended using chains passing through the lifting holes for hold downs.
The forklift forks need to be close together to allow the grinder to be placed on the 4x4's at the edge of the base. The lift needs to be done slowly to avoid having the grinder tip over. A rope securing the grinder to the forklift mast is good insurance against a spill.
It is tempting to just use two straps on the grinder frame. One is placed between the column and saddle. The other is placed on the front of the saddle. The straps are pulled straight down by the strap winches. The first strap works well. The second strap on the saddle will cause the saddle to rock and lift off the ways when tightened. This strap can be made snug but it cannot be tightened as normal without damaging the grinder. The saddle strap will not be effective in holding the grinder in place on the truck bed.
The grinder table is held down by the spindle casting which is resting on a wood block. If you have the table clamp installed or there is oil in the hydraulic cylinder the table cannot slide. Additional straps on the table are not needed. The wings on the table are aluminum castings held onto the center cast iron section with two bolts. Putting a tie down load on the aluminum wings may cause them to break.
The table clamp is a rectangular plate with a slot and two holes. The slot engages one of the table stop dog rail standoffs. The two holes match the threaded holes on the left side of the saddle.
The saddle uses a ball screw. To prevent damage to the screw during the move the saddle clamp on the left side of the grinder needs to be tightened down.
The bolts holding the left and right hand magnetic chuck clamps also need to be checked. The accepted practice is to tighten firmly only one of the bolts to allow for thermal expansion of the chuck. When moving the grinder both bolts should be tightened down.
The grinder was sold with a blue tool box. Maybe 8"x10"x3" in size. The box will have the table hold down clamp, the wheel adapter wrench, a wheel adapter puller nut, the base adjusting screw wrench and maybe the lead feed for the adjusting screws.
Ask the seller if he has the balancing arbor for the grinder's wheel adapter.
