Hi,
I've been asked to make some replacement power valves for a 2-stroke motorcycle. I had the material analysed, and it's 2024. I forgot to ask for a hardness test to see if the temper could be determined.
I don't know what the max temperature is that the part will see (it's on the edge of...
Hi forum,
I have been given a wheel that has hooked teeth on the periphery that is used to cut up recycled plastic. I have to replicate the part, including if possible the material.
Using emmision spectroscopy the testing lab thinks it appears to be similar to 1552 steel. the constituents are...
We have made a part that requires us to analyze the part using AFGROW fracure prediction software.
The customer specifies that we need to conduct the analysis using an initial flaw size of .03" long by .015" deep. With the part we have made we are getting marginal cycles to failure.
Can mag...
Using the classical model of a single edge corner crack (not the one with the user defined beta solution), a crack with the dimensions of A = C = 0.015625” is applied to a specimen with the dimensions of 4” width and 0.120” thickness.
A max stress of 41 ksi and stress ration of R = -1 is...
Hi
I'm looking for 316H bar 6in dia for a project I have. It needs to have a min carbon content of .39%
Does anybody know of any sources?
I appreciate any help anybody can give me.
Hi All,
I have an application I'm designing parts for. Due to space requirements I can't use 2mm thick needle thrust washers. To make it work, the needle roller thrust washer can't be thicker than 1/32in.
Are these availible in any dias? I've looked but found nothing.
Thanks in advance for...
Hi all,
I'm looking for Aermet 100, 6in dia bar x 82in long. Our normal supplier Fry's doesnt have any, and apparently will not be getting any soon.
Does anybody know a supplier, in any state who might have such a piece? Even 2 pieces 41 in long would work.
Even Aermt 310 might work.
Thanks...
Hi,
We will be welding a 316 elbow, to a 17-4PH pipe using hastalloy W rod. The assembly will be used to feed high pressure air (1000psi) into a plenum.
Our customer was asking if there was an ASTM spec (technique) that we planned to use. Is there an ASTM spec that covers welding of...
Hi All.
I have an application that needs to be made from 6061-T6 and will need to be anodized for intermitant service in seawater.
I have been told that Type III Hard Anodizing (.002 build-up) may cause fatigue cracks in the Anodized layer, that could lead to corrosion at the crack.
Does this...
A question,
Apparently we are having trouble obtaining 2-56 and 0-80 SHCS AND FHCS. We typically use Unbrako 1960 series or Holo-Krome fasteners. Unbrako being for us the industry standard.
Apparently both manufacturers are not making those sizes, at least not that we can easily obtain off the...
Sorry for the double post, the title I revised to hopefully garner more answers.
I have an Aermet 100 maching question for the forum.
Due to a fatigue issue we are trying to avoid, we have made some parts from Aermet 100, and in the critical areas we have left .015" of stock to be machined off...
Hi,
I would like to control a DC Gearmotor.
What I have done in the past is to have 2 limit switches that limit the travel of a part attached to a leadscrew. The limit switches kill the power to the motor to stop the mecahanism.
However the precise point at which the mechanism stops is...
Hi,
I am designing a Worm drive that needs to drive a leadscrew. I have calculated a Torque req'd to drive the load to be 442in#
For packaging reasons I want to use an 8dp 20T Bronze gear and hardened Steel worm.
Is there an empirical equation for Wormgera strength I can use?
I have found in...
I work at a facility that makes aerospace test hardware. We have a requirement to make a part from Aermet 100. The part is highly stressed, with a Factor of safety of 3 on UTS. We have been told not to use Vascomax350 as it's too brittle. and have chosen Aermet 100 as an alternate material.
Our...
I have a problem, in that the delivery time for the Globe MIL-M-8609 gearmotors are longer than our requirements can stand.
I was going to order the SD gearmotor (.75" (19.05mm)dia)with the 2799:1 ratio, but I need an alternate supplier.
Does anybody know of a manufacturer that makes DC...
To all the corrosion experts on the forum:
I have a prototype of a product that is made from 6061-T6 AL. The 3 major parts are made from 6061-T6 and articulate at 2 joints. 2 of the parts are drilled to create chambers that will contain high pressure air. This device will be used in seawater by...
Hi,
I am contemplating casting a product in Al 356. If I make a mold to make wax patterns, does anybody know the allowance I need to apply to apply to the cavity to account for the wax shrinkage, and the Al shrinkage.
Regards Dave
