I made a small pilot hole with a center drill. That provided a really good start for the 7/32" tap drill. I also used a countersink cutter to add a chamfer. This makes it look nice, and also helps the thread tap get started. Step 10: Tapping the Threads I used the tailstock cente...
Those 3-lb. dumbbells collecting dust in the closet could be turned fairly easily on a lathe. The wide, relatively deep recessed area where your hand grips the bar can be turned with a simple grooving routine, a feature that would be murderous to cut on a milling machine. A small teacup...
When installing or removing milling cutters, always hold them with a rag to prevent cutting your hands. While setting up work, install the cutter last to avoid being cut. Never adjust the workpiece or work mounting devices when the machine is operating. Chips should be removed from the w...
Cut off the selvage edge of the fabric. That’s the white strip on each edge that doesn’t match the pattern. Try to make the cut as straight as possible. Using acutting wheel* (rather than scissors) to do this makes a clean edge that doesn’t fray as much. Using scissors or the ...
and for making clearances at various places. I used a few threading taps to cut threads in the aluminum seatpost binder block and the front derailleur backing plate. Of course, I needed the proper-ratio epoxy-dispensing pumps ("mustard pumps") from West System and epoxy spreading rollers (li...
computer controlled motors. The lathe tool which are controlled by the computer are known as CNC lathe machine used for mass production of parts. These are commonly provided with a variable ratio gear train to drive the main leadscrew which enables different pitches of threads to be cut. Some...
CNC robots have the same kind of issues. Bear with them. For instance, no cutter will be able to drill a 1 mm diameter, 1-meter deep hole. Picture it in your mind for a second. It is too deep and narrow. Similarly, a CNC robot arm with 2 “elbows,” a total length of 1 mete...
I had sum bike pegs I was going to use but they had imperial threads and my clutch used a metric thread and I didn't want to make an adapter so I decided to make my own. I needed a lathe to make my own but so dad knew a bloke with one and he made it for me. it fit nice...
turns out for the FKM's I'll just use the scatter gun approach and hopefully be able to learn something and pass it on. My machinist mate recons that with a cheap little XY vice attachment on the pedestal drill and a 2 fluted mill drill you can cut the slot accurately in the plunger...
Upon moving in, the kitchen had wall-to-wall, floor-to-ceiling cabinetry with little heart cut-outs. Our ceilings are quite high and the windows transom, but because of the large…mass of wood cabinetry, the space didn’t feel open, or bright. I could fit our entire Brooklyn apartment ...
