First thanks for any help.. We are using a bar of 2024-T3, approx 1-1/4" x 1-1/8" x 9" with male and female lug profiles, one per each side for mating parts. Male width is .770 and slot depth is .231 and the female profile width is .780 and profile extrusion is .233 which should give a .010...

I am looking for a company that can supply a multi-head riveter. We are using 1/8 rivets and placing them on 1-inch centers, from a minimum of 6 to a maximum of 12 rivets. We would like to have a toggle switch to select which rivet would be applied. Needless to say, I dont know if this is...

NickE, your correct...my verbage takes another hit

I have considered ribs (which I probably classified wrong, as grooves). Is there calculations which will help me determine how many ribs (grooves) are needed and how much doing so will strengthen the sheet metal. Gussets, unfortunately, are not an option due to space limitations.

I am using 26ga. sheetmetal (9-3/4 wide) with two tabs welded (for self tapping screws), however, the the srews are torqued the sheetmetal bends. Will placing a groove across the width of the metal (over the top of this section) provide enough strength to overcome the screw torque? Can anyone...

What is the best method for determining a part mating sequence. Such as, (ie..)48 different, or final, parts use a combination of 3 components, which could be interchanged to produce wrong parts. Would like to use mating pins and cleanace holes. Is there an easy method for determining the...

Thanks, that twice you have been a help to me, I appreciate that. Thanks, dougwdicar

Question: I need some help finding the shearing stress of screws holding a shaft to a drum. T = 6724.08 (lb in.) Number of bolts = 6 Bolt Size = 5/16-18 X 1-1/2" Plate thickness = .750 Bolt Circle = 2-7/8" I know I can increase the size of the screws to 1/2" dia w/close fit...

You might want ot look on the web for Steriolithography companies, then view each of their materials physical properties, to match to your needs.

Yes, the weight is evenly distributed, throughout the drum.

First, I havent done these calcuations since school. I have a drum, which weighs 400lbs (24"Dia. x 12"W) supported by two stub shafts (1.688"Dia. x 12") rotating at 1750 rpm. I am trying to determine the intertia of the drum, so I can determine the torque required to stop...
