Dr Rocket case length

Can someone give me the exact length of the Dr Rocket 75/6400 M-1315W case with both closures installed. I have a few different lengths, but I'm looking for an exact measurement. Thanks.

Why don´t you look at the following url:

Ik think this will be sifficient.

sorry

Loose the dot behind the url:

sifficient is meaning sufficient

Arne

Sorry again for wasting all this space.
I noticed after a closer look that Dr rocket doesn´t have the right length.
Or a lenght at all.

Yeah, I know. Thats why I need the length. Its the only case on the Dr. Rocket website without the length. Thanks.

The motor tube length is 31.52 inches with out the end caps. I will try to get the rest of the dimensions, with caps, today.

Cya,

Carl

Thanks, let mw know.

Well according to one of my vendors whom I do trust, the lower closure is about 1/2" thick after being installed in the tube. This is the overhang lip which protrudes externally from the motor mount.

The upper closure is a "plugged" closure and he said it protrudes from the top of the tube only about 1/8", as the majority of the closure is threaded into the tube.

Hope this helps,

So it is safe to say it is less than 34 inches, right? Thanks.

yes, by a few inches less.....remember that you really dont need to consider the lower closure since it sticks out of the rocket anyway....the upper though is the ticket and we appear to have it covered.

No, No, No! Although the forward closure is plugged, the internal area for the delay element is still there; as well as the knurled forward end of the closure. I'll check my files and send the information ASAP.

Would the person who wants the dimensions in question please e-mail me. I would be only too happy to provide them to everyone on the list, but unless the rest of you have some type of CAD software your capability to view the file are somewhat less than nihl. A fax number would be a big help! That way, I could send a copy of the drawing replete with linear dimensions.

Howzabout posting a screenshot that shows the drawing within the CAD program? Should be OK, I guess we only need the measurements.

Please tell me how to do that and I will gladly comply.

Which part are you not sure how to do? Creating the screen shot or attaching the file?

You can attach the file using the Attach File: feature when you make a post. Your file must have one of the valid extensions: gif, jpg, png, txt, zip, bmp, or jpeg.

If you can export the drawing from your CAD package into one of the image formats listed above then it should be no problem.

I'm very sorry for the inconvenience of my ineptitude and the angst that it has created. I'm a machinist, not a computer whiz. I'll see if I can convert the file and attach it.
Thanks to all for your patience.

How do I attach a "screen shot" ? Converting the file to any of the formats you made mention of ain't a happenin' thing.
But Hey. . . How's about sending a fax number so that I can send the drawing to that number and you can paste it?

I don't have a fax myself. What are your choices of output to soft copy? Your software should be able to export the drawing to something that is universal. How about to Postscript?

If you can put it in soft copy and email it to me I might be able to get it on the site.

dxf (drawing exchange files) are universal, and so are bitmaps. However, if this file were converted to the format of a bitmap it would more than likely be rejected at the office of your mail administrator because of its size. The biggest part of the problem is that CAD Software (regardless of its trade name) has been designed in a fashion that negates the transferal of drawing files unless the recipient has even the most minimal of capabilities to receive them.
Ok, here's the deal as best I can tell it:
The overall length of the forward closure, from where it butts against the forward end of the motor casing, is 2.178 inches.
Forward of that abuttment is a knurled affair that is approximately 2.26 inches in diameter and another one that is approximately one inch in diameter with an internal thread that can be used for retaining the motor inside the rocket's airframe.
Once again, I apologize for the inconvenience any of my readers may have experienced in enduring the obvious displays of computer illiteracy in my posts. I thank each of you for your patience.

Here's the deal. Open the DXF file in AutoCAD or whatever-CAD. Have the view set to the whole casing as large as possible, the way you would want it to appear in the forum. Press "Print" on your keyboard. Open a paint program like "Paint", "Photoshop", "Paint Shop Pro" or whatever you have. "Paint" comes along with Windows (see "Accessories") and does the trick. Once you have that program open, select "Edit -> Paste". The whole screen should appear as an image in the program in the state it was in when you pressed "Print". Save the image in JPG or GIF format.

Now go to the forum, post a new post, while doing that, insert your file, like so:
<img src="https://www.shuttle-endeavour.de/webimg/attach_file.gif">
Then "Submit Reply" and everything should be working.

If you have the latest version of Paint you can save the file as a jpeg. See the attached image for an example of what this looks like. The problem with the saving as a bitmap has already been alluded to. The file size will most likely be too big.

I think I did it

Yes you did. Cool.
