I need a recommendation for a specialist in solenoid development to maximize the potential of a solenoid we wish to manufacture.
I would prefer a company in Brisbane Australia but its not necessary.
Hi, I moved this post as I had parked it in the wrong place.... Sorry :sick:
Could people smarter than me fact check or advise where I'm right and where I'm wrong. TIA

I'm well out of my comfort zone sorry 😐. I would like to develop our own design and understanding. I have had quite a good look and only seem to find very basic or very advanced topics, I was hoping for some middle ground for dummies

I'm headed into retirement and want to plan a toy to build for fun, for me. It won't necessarily make sense to others but it will to me.
I have been around Subaru Impreza Tarmac Rally cars a lot and have a shed full of parts so I'll make use of those.
I'd like to design a space frame for the...
We use 24Vdc 1.2Amp solenoids. Some of these can have cable lengths of 150m. We use either a bi-directional transorb (limits spike to 33V) for latching solenoids (reversed polarity release) or a diode for non-latching.
We have had no issues from any of the companies that supply and install the...
I have experienced circlip failures where the circlip fractures/separates in what appears to be similar to crevice corrosion.
The 420SS circlip is fitted on a shaft of 303SS which passes through a rose of 303SS, over the shaft and between the rose and the circlip is a 304SS washer.
The...
Are you better off with more cylinders with a staggered firing order to smooth the flow through the restrictor to keep the flow rate close to peak throughout the cycle or is it better to have a single piston to increase pressure differential across the restrictor.increase air speed and have a...
I have been looking a chart or similar for choosing a thread size for taping into 5000 grade aluminium sheet. I can find "rule of thumb"type information from 1x to 2x the thread diameter for thread depth but this is not specifically for sheet metal with only one option for thread depth. I'm...
I'm trying to design a rotary to rotary drive 1:1 similar to a spur gear but with one contact face only as the driving part must return and lock in its start position while the driven part remains in its new position but is free to return under some circumstances. These will be in a low/no...
I'm having trouble finding information on shear loads for clinch studs.
In particular these are SS400 material studs - M4 X 12 pressed into 3mm 304SS sheet to attach 2mm Zinc plated black mild steel brackets that will be subject to impact loads. I note they have reduced torque settings over...
I'm having inconsistent results using magnets and hall effect switches and it seems to be temperature related. The temperature can vary between -5°C and +40°C. The manufacturer states there should be no change in the strength of the magnets in that temperature range. I have eliminated all other...
I'm considering using a self bailer on a boat to draw out water from a well in the hull (Self bailer image linked). It swings down into the waterflow. Waterflow can be anywhere from 3 to 20kn. When the well is empty the bailer will be 350mm below the waterline. For it to be successful it will...
I'm looking for a symmetrical and an asymmetrical foil.
1. A symmetrical for a horizontal foil to fit to the rudder to reduce pitching on a sailing catamaran.
2. An asymmetrical to run in the upward waterflow rising up the stern to produce some forward lift.
The boat is a performance cruising...
For off-road use.
For a given tyre size - 35" X 12.5" X 18", when the air pressure is dropped to 10psi from 40psi- am I better off with an 8" wide rim or a 12" rim for straight line traction and which one will wrap around ground irregularities like rocks better?
For off-road use with outer beadlock wheels.(Braid system B Beadlock which is a lighter duty Beadlock)
I was thinking the narrowest wheel with the widest tyre would flatten out more for a given air pressure and be an advantage in straight line drive traction over a wider wheel.
But I'm not...

I'm not an engineer so be nice 😡
Sorry to drag this topic up again, I have read the info here and elsewhere and still struggle with it. Can it be explained or demonstrated with vector drawings with a large amount of layman terms.
I'm in the camp that says no such thing as a free lunch. If it...
I'm designing a T Foil rudder to go on the bottom of an existing catamaran. I would like to include an engagement/disengagement mechanism that can be used in motion. To simplify and reduce weight in the control I'd like to position the pivot slightly ahead of the point of balance.
Is there a...
