I had checked the threads against my thread gage earlier, and it confirmed 27tpi. I remember also checking the 1/4-28 and it was 28tpi.
So thanks for the help, it's time to pick up a tap. Looks like I'll have plenty of time to play since Virginia has a 6/10 date for lifting the stay-at-home...
The zerk was to squirt grease into a mower spindle. Not a critical project, just something I thought of doing (since I'm sort of confined to the house). I do see 1/16 NPT taps, I guess I'll just order one.
Maybe zerk fitting just have a history and story of their own!
The hex is ~0.315", thread od is ~0.238 (not the 0.140 above), the thread length is ~0.185". The package came with several shapes to the zerk (straight, angled, right a.) and 2 thread sizes. They are listed as 1/8-27 or 1/4-28, some...
A 1/8-27 npt tap is probably close to twice the diameter of this zerk fitting. The fitting is a standard one with threads that came in a pack I got from an auto parts shop a few years ago. The od of the threads is ~0.140".
I have some threaded 1/8" zerk fitting that I want to use, thread is 1/8-27 npt. A 1/8-27 npt tap is larger than my zerk, so it needs to be smaller. I checked my 25th edition of Machinery's Handbook but didn't find an answer. I did seen a tap on the Grainger site...
I'm an occasional user of DS and have wonder if my issue is a common one. When I'm drawing a line, or other tool, it seems like I have to wait in the vicinity of an 'end point', 'midpoint', etc. label to show. Or at least to wave my pointer around a bit. Plus they don't always show up. My...
Ok, that works well, thanks!
It sure is hell (learning-wise) moving from a program that I've used for about 20 years to a new one. If only it wasn't a 16 bit.
I'm new to DS and am slowly getting the gist of it, but one thing is eluding me.
Say I draw a rectangular part. Now I want a hole in from left edge, say 1/2". I've been using a dimensioning tool for this. In this case I would insert a 1/2" dimension to mark the first hole line from the part...
Thanks for the help folks. I did get a copy of the Autocad book Mike suggested and it is helping.
I started playing with the OFFSET command, and it does do something similar to a technique I use with the old program..
Now I have to go back to DS's Help Instruction to clarify how to set up the...
I haven't gotten to that command yet. I was hoping that my limited background with Vellum would let me get a simple drawing going, but it seems not. I'm starting to look at the DS Youtube tutorials and did find, and ordered, an old copy of the book Mike suggested. Looks like I just have to...
I just d/l DS. I'm lost! FYI, I'm a hobbyist coming from a 1998 version of Vellum, which does not run on 32+ bit machines. The couple of tutorials I've looked at seem to entail drawing something sort of free form, then going over many commands. But they don't really show me how to draw a part to...
I think I just misread the deflection formula. I believe 0.221 is a given number which changes depending upon the shape of plate and extent/type of edge support. I would have read MH this correctly except that I found an example on a web site that had a different number for the same plate. It...
Ok, I think I've read that those formulas are approximate solutions, I don't need greater precision.
But my question is, where can I find this value? The MH example I had above is for steel. I found another example for lexan and the value was 0.0284. It seems there should be a table or...
Hello,
I'm a hobbiest, not an engineer, and I need some help. I want to calculate some plate deflection numbers on circular plates using excel. I know there are on-line calculators that will do it, but I want to keep it in excel. So, my copy of Machinery's Handbook gives the following 2...
