1/87 Model Trucks/Joe Enriquez
During the workday, Joe Enriquez operates big trucks and heavy equipment. For a hobby, he makes models of them in HO scale. Like Augie Hiscano and many other modelers who started out building kits, Joe has taken his skills to new levels with each model. He likes working with plastic as a material, but on his latest work only a few parts available commercially are used, and even those are tweaked to add or bring out more detail. Many are now turned from metal on his Sherline lathe. HO (1/87th) scale is a popular size, and a lot of parts and vehicles are available commercially; however, Joe prefers to scratch build models of unique equipment not available on the store shelves. His day job helps him get the details right to make his models look totally authentic. It must be quite a change of pace to come home from a day of operating extremely large, noisy and powerful equipment and sit down to do such tiny, delicate work.

Shop Tip of the month
Dual use for 3013 step block hold-down clamps/Hamilton Elliott
For years Sherline has offered the P/N 3012 clamp set. In this simple system, the clamps are adjusted for height using an upside-down º-20 carriage bolt threaded into the rear of the clamp and a T-nut and a 10-32 screw near the front of the slot to pull down the nose of the clamp against the part. The P/N 3013 step block hold-down set was introduced later to offer a more versatile set with a larger range of clamping heights that is quick and easy to position. However, by simply drilling and tapping a º-20 hole near the rear of the step block clamp, a carriage bolt can still be used when there is no room for the step block in a tight setup.
††The Standard 3012 hold-down clamp
†Drill and tap the step clamp and use a carriage bolt. Position of the hole is not critical as long as it is on center with the clamp.
TIP: When using carriage bolts to support the rear end of a clamp, place a 5/16" washer under the head of the bolt to keep from putting dents in your mill table when you tighten down on the clamp.

Did you know?
ï The microscopes available for Sherline lathes and mills have been changed. While still made by the same manufacturer and featuring the same high quality optics, the magnification has been decreased by almost one-half to give a larger field of view in the lowest powers. A 1.5x Barlow lens is now included to bring the viewing height back up to a comfortable level while still allowing a slightly wider field of view. The included metal base stage is now top lighted instead of bottom lighted making it more practical for use as an inspection scope. The microscope and lathe mount can be purchased as P/N 2125 ($775.00) and the microscope and mill mount are purchased as P/N 2127 ($865.00).
