drilling problem
Fabrication of Drill Jig is a good Mechanical Diploma Engineering project.This Jig is useful for drilling multiple holes in flange type component. As per the component jig plate may be changed and jig can be used for various types of components.Use this for your reference and study.
This drawer pull design had been kicking around
in my head for a couple of years before I finally
got around to using it. The rough sketch in my
notebooks evolved into a finished set of
dimensions in the course of designing a small
curio cabinet. The bars are made from air-dried
walnut scraps. The standoffs are red oak, and
the cross-pins are bamboo shishkebab skewers.
The first jig to make is the master spacing jig.
This is used to drill uniformly spaced holes the
diameter of the dowels in an assembly and
finishing jig as well as in the finished drawers.
A nicely squared up scrap of hardwood or MDF
works well for this part. The dimensions are
not critical. As you can see from the drawing,
centering lines are brought around the edges
to aid drilling drawer fronts.
