Old Dimensioned Mechanical Engineering Drawings 1

[goodguy1405]

Does anyone have any resources as to where one could download these types of drawings? I find they are good practice to do in spare time. Thanks

goodguy1405,

What is it you are practicing?

Find a used book store and look for an old Drafting/Mechanical Drawing textbook.

I am practicing Solidworks. I like to keep my mind sharp and draw new things to challenge me. John: It is sad that when I go to the bookstore and ask where the engineering section is they point me to a very very small area and there really is not anything there worth reading.

Any library from university/college libraries, college towns or large cities would be ideal hunting grounds.

Google was less help than I thought. only tried "old engineering drawings" and "vintage engineering drawings"

vintage technical drawings wasn't much different

not really mechanical drawing related, but I found them interesting none-the-less.

goodguy1405-

Just to be clear, what you are asking about is a source of dimensioned drawings of mechanical parts that you can use to make solid models of in Solidworks? Or do you also wish to reproduce the dimensioned drawings in Solidworks? If you wish to reproduce the dimensioned drawings in Solidworks you will need a 3D CAD model to generate the drawing views from.

There are many willing to pay for this type of work. So rather than doing this for fun, I'd suggest looking for someone willing to pay you to convert their legacy paper drawings to 3D CAD models and digital drawing formats.

Yet, another confusing question.

Why can not anyone state specifically what they mean ?

I will try to help with the confusion. I am looking for old mechanical machinery drawings or the like that have the actual dimensions they used to build the machine so that I may model them in Solidworks and try to replicate their drawings for practice. I want to master Solidworks and all that it has to offer. Thanks

I would love to freelance, but unsure where to begin.Any help would be appreciated. Thanks

They may not be detailed enough, but you might look at older patent applications.

Goodguy1405:
This site, Eng-Tips, is supposed to be a group of forums for engineers, drafters and technicians working in a professional technical capacity. You should have read this and agreed to the site rules when you signed up to be a member of the site. If you are working in this capacity, for a consulting engineering firm, for a product manufacturer, or some such, I’m surprised that you are having any trouble finding product and parts, details and drawings. So, what’s the real story here? Go to a Uni. or Vo.Tech. bookstore for used books on some of these subjects, or to Solidworks for tutorials. Why not go to some friendly local product manufacturer and ask them if you could have copies of a few different product parts for your study and use. Explain what you are doing and why. Maybe offer some trade, in your time, for something they need. Ask a friend who is an engineer at such a company, he/she might be a mentor of sorts. Maybe you should measure a few part, put some tolerances on them (based on variations), and then draw (model, Solidworks) them, so they could be made/manufactured. Then, take those drawings to someone who will critique them for you. You will learn something else also, in doing it this way, accurate measurement and its methods, some tolerancing, some consideration of the sequence of manufacturing steps, etc.

dhengr: I have drawn everything here at my company including random parts and machines in our shop. I just like to draw and learn more each day. I have been through school and have drawn all those drawings as well. I am the Mechanical Engineer here at my job. I didn't think I was asking too much to see if anyone had some extra drawings to do. I have used the site quite a few times to get answers to hard questions I had and enjoy this forum as well as others I am in. Thanks for all the help and any drawings available.

Talk to your machinists and draw them some fixtures (or draw fixtures they have already made.) Creating a drawing/model from someone else's rough concept or from a physical part, is much more of a challenge than doing it from a fully dimensioned paper drawing.

If you're really bored, model the shop and office spaces and make a plan to optimize equipment locations.

 

[goodguy1405]

lol Already done that for the shop. Fully optimized. I will draw something else in the shop today. I do like doing that since it is hard to get any drawings from here. Thanks all.....

Trouble is many actual detail drawings will either be proprietary and/or in a format not very suitable for sharing over the internet.

Plus for various reasons old drawings often get destroyed when no longer required - or only microfiched versions are kept in a dingy port-a-cabin somewhere in a govt contractors site...

What you could do is look at some vendor catalogs/data sheets etc. and create models from their data. Pick a type of component you're interested in drawing up, do some web searching of vendors etc. until you find some kind of data sheet and away you go.

A great place to start would be to contact any organizations that are involved in restoration work (auto museums, aircraft museums, etc.) and offer your services. These organizations often need CAD models made from legacy engineering drawings so they can machine replacement parts using CNC equipment. Sometimes they require CAD models/drawings to be made just by measuring an old part, so they can manufacture replacement parts. I would imagine doing CAD work where you get to see the finished part made from your model/drawing actually being used would be much more rewarding than simply making drawings for practice.

Thanks for the information that all have given in this forum. Tbuelina I will take that into consideration and appreciate the advice. I draw and draw and draw to be able to give the customer whatever there heart desires. I want to master the skills of Solidworks and Machine modeling and drawings. Good luck to all in your endeavora.
