Hello,
I'm playing in the garage (again) fixing some air equipment related to air fittings on my car and bicycle(s) wheels. I'm looking at using a presta valve core (normally used on cycle tires)in a housing.
Is there a specification somewhere for the threads and such (housing and sealing edge...
I am looking to see if this is possible and that someone may be of some assistance.
I am currently working on a robotic concept that utilizes a hollow flex shaft drive - the flex shaft would be required to transmit a rotational motion (slow motion and only 360 degrees in total) plus a pull load...
I'm starting work in a new field as a draftsman. Looking for an overview of how small parts and parts 2mm in size used in a mechanisms (3 to 5mm in size) are manufactured - if Titanium, are most parts EDM machined and what are the limits of detail size? If plastic is everything moulded at this...
Is there a way of to query the model or assembly member to display the units of the model.
Specifically I have a column in the BOM report that displays the mass of an item (pro_mp_mass) but I wish to display the units (lbs, grams, Kg)
Anyway of doing this?
For sake of argument I am buying a piece of 6" aluminum plate against AMS-QQ-A-250/11 - in reality what is the real usable thickness of material that can be 'used' in a design? - or worded in another way - forgetting about flatness etc.. how much cleanup it normally taken per side to accounting...
None of the books that I have seem to show things like corner rads (inside & out) on square or rectangular profiles is there an online resource or a rule that I can use to figure out what the values are? IE inside rad is a function of the wall thickness and uniform wall gives the outside rad...
As a designer I am often asked to conceptualize items, depending on the product and method of manufacture I consider what material is available. For steel and Aluminum I use the typical "books" from suppliers (realizing that all sizes listed are not always whats available). I am presently...
I am looking for basic bump (G) value - If I would use, say 3g at the wheel - what effect does dampening have on a object mounted to the chassis/body - would this mean that 3G would be to high a value?
- which opens up the question a bit to... if bump is the highest value then use this value to...
I have a large assembly that has a number of common parts between 2 simplified reps. To create a drawing and to make parameter call out on the drawing easier I would like to use the family table function calling the parameters and the simplified reps. I could create the family table calling out...
Putting together a concept model - part of the prototype are aero covers for the headlamps - what material to use (sheet form) that could be vacu formed to shape and be usable/durable - functional as opposed to something as a static display.
I had thought about polycarb - looking for...
Purely a theory question...
At what point can one say that a vehicle will become un-drivable when dialing in additional HP and torque. What I mean is - is it predictable or calculable for a given wheelbase/tract width ratio and tire size to roughly estimate that above a given HP/torque there is...
Very open question and not a simple answer - could someone outline what influences overall mechanical grip in suspension design and vehicle design for that matter. If you can give give some detail that would be helpful. I am just trying to understand some sports cars seem to do better than...
I have the task of 'fixing' a large number of parts that users have checked into Intralink that are missing parameters. I believe that my only course is to check out and open each then edit the parameters and check back in.
I see that a BOM_report can be done within commonspace - can is there a...
Just out of curiosity on how others do their work, when modeling a cast part - say an engine block, do you start with a big chunk and remove material or do you build a piece at a time. Same with a plastic molded part - start with a big block and cut away ?
TIA

Can anyone give me some hints about modeling an equal length header system in Pro/Engineer. Obviously I have multiple starting points and a desired finish point that is a packaging constraint, plus the volume that the finished item will take up (or area that will be allocated for the exhaust...
Hopefully someone can help me here. I need to have 2 gears in a disengaged position. During operation normal use - one rotates and the other is stationary. When required I would like to engage the teeth of the gears engaging a damper to control the rotation of the first gear. Since the first...
Different manual gear boxes shift differently - some shift like a knife in butter, some not. In particular the notch that is felt in some boxes as the change goes thru neutral. What design characteristic creates this. Is it related to synco, gear or shifter linkage design?

1) Looking at aftermarket stuff, air boxes are removed and a less restrictive tube and filter are put on - smoothing out the flow (in theory). However these are subject to water pickup if the intake tube is low to the ground and under hood temp because most of the time the filter is in a convent...
