Why is it that none of my various phillips screwdrivers fit that small phillips screw that is very tight in it's hole? Is there a standard for the angle of the tip of these drivers? I have some Snapon, Wiha, and other high quality drivers, none of which will properly fit into the head of some...

I need to make a pair of shock absorbers for my model airplane, and wonder if there are any ideas or plans out there. They do not need to be hydraulic, only sprung. They are for a large Pilatus Porter weighing about 7 lbs. and are about 1/4 -5/16" OD. Ideas?

I am milling some black delrin pieces and am experiencing growth of the part after machining. That is to say, the holes I mill and drill are smaller that the tool that cuts them. Is this due to spring back of the material, or does it grow afterwards?

In today's paper: ..."physicists have made their own purified form of copper underground-some of the purist on the planet-and built an underground machine shop to make parts with the copper." This is 1 mile below ground in an abandoned gold mine in South Dakota. They are looking for light rays...

I would like to see a book published showing how to build model engines. It could be written by one or more of the experts and accomplished people on this forum. It could even be published by the Forum. Each chapter could be written by a different master expert in a chosen topic. Steve, George...

How do you polish your cam shafts and cranks I have 3m diamond sticks, and emery cloth. How do you get those shiny glass-like surfaces?

Decided to get some ER 32 collets for my 10K lathe, which has an MT3 spindle. What kind of drawbar should I use? Some ER's are available with 1/2" thread on an MT# shank. Is that the best I can do?

I frequently need to work on small, round pieces on the mill, so I made up this simple mount for my Sherline chuck on the Mill table. Trivial, but helps.

What is this spark plug? A Plasma? I want to get it a partner for my twin.

I am looking for some ideas for an engine mount for my silver bullet. It is getting to the stage where I have to mount everything in position, and maybe someday, run it!! So, I would like ideas for cool looking motor mounts. Anyone?

Is it possible (for a novice like me) to make a tapping device for tiny taps..something with a clutch to prevent breaking small taps? I can't afford a Procunier or Tapmatic, at least at the prices I see. I now use a spring-loaded holder in the drill press or mill. Still able to break them.

I am making new valve cages for my Silver Bullet, that are now Drill Rod. Would cast iron be a good choice? This would enable some nice valve seats, I hope.

I have a broken off a 2-56 tap in an aluminum head that I want to try removing with alum. If I immerse only the part of the head where the tap is in the alum solution, and keep the rest of the head (with the valve cages) above the surface, will this allow me to get only the tap to dissolve?

Which do you use, a center drill or a spotting drill to locate and start holes? Do you sharpen them when dull, if so how? On a drill doctor? What angle?

I see some terrific photographs of our models here, and I am not able to take pictures that are good. How do you guys do it? GBritnell, yours are so good, well lit, in focus, etc.,? Could someone be very specific and help me with lens, aperture, lighting technique, EV rating, etc., etc. I have...
