I'm just speculating, by looking at the worm, that the interference may have been caused by the worm not being extended far enough along the length of the shaft. The type of worm and worm wheel that...

Thermoset plastics are typically formed by compression molding at temperature.
If you are interested in a high temperature plastic that you can machine for prototypes, look at Dupont Vespel which...
Have you considered thermoset plastics?
How hot does the part get? Can it be a burly engineered plastic?
Have you thought about a thread insert?
most threads are actually rolled. The threaded section was probably about pitch diameter when the part was headed and then the threads rolled on that section. You are right about most being...
Your 304 material appears to have be formed to create the flange. The forming stresses and work hardening are not something that can be known to the forum viewers. Was the material annealed after...
Many threading dies have a gap that allows the die to be closed a bit by the set screws that hold it into the die holder. Does your die holder allow this adjustment?
Span? 16' is about max span for a 2x10 check the tables and the grade stamp on your joists. Some codes allow floor sheathing which is pretty thin and the deflection will vary with the cube of the...
I'm voting for taper lock split bushings and matching hub. You may not need the key depending upon the torque applied. They hold really well.
The indexer jboggs mentions is a good idea. Also investigate shot pins to position. The name Ferguson drive comes to mind as well.
Why do they have to be on a turn table? Or why can't they be moved in a straight line? How accurate do they have to be for measurement?
likely done as a stamping.
Did you look at drawn over mandrel tubing? (D.O.M.)
Your rotary engine becomes a stationary engine. The rotor must rotate to maintain the tips of the rotor in contact with the case as it the eccentric moves on the output shaft. The gears maintain...
If you are concerned about undercuts and using involute profiles, look into long and short addendums.
The term spur gear usually refers to a straight (parallel to the axis of rotation) cut gear regardless of tooth geometry. This differentiates them from helical gears which have teeth cut at an angle...
There are lots of old wooden boats scrapped for being rotted. My cheap self would look for something to salvage. However, the tiller has one big advantage in that you can control the throttle and...
Jboggs is correct, the electromagnetic clutch in the gearbox is unusual.
The first step in your redesign is to move the clutch to the input shaft on the exterior of the gearbox. The input shaft...
Following up on Kelly's idea, look at overrun clutches and one way clutches.
Your description is vague and the best engineering design cannot be made without a complete review of the design elements in your installation. So this cannot be a recommendation.
However,...
Do not worry at all. You will face disappointments in life magnitudes greater and still be a winner. Lots of ways to become a better job candidate:
Walk into a local machine shop with safety...

An increase in the outside diameter of the axle is the fastest route to increased stiffness.
If practical, I suggest that you put a length of 1" PVC over the 1/2" and use a reducer at each end to...
I don't know what your formula is intended to calculate.
I calculated the total shear force on the bolts and pins based on your 55 ft-lbs.
That force is in lbs force. I then calculated the...
