Steamchick had it right with the drawings from the Kensington Science Museum (SMG now) In 1977 I was at the Wembley show and purchased a set of drawings from them. Was told at the time that they had a model (1/8" scale) made in the late 1800's and they drew the plans in 1937 and they were...

Marty, it is ~ 7" x 3 1/2 " x 2 1/8" And I understand it was for a #4 Burke mill It seems to have been made by Burke for their mill, but i have no verification as it is a very old vise I used a toe clamp to hold the vise down but have only used it one time . I assume thats what they did on the...

I have a Burke Vise which is 4 inch for $200 Made in USA for Burke mills In good shape but was used Has factory handle Hope these photos can be enlarged Rich Edit.. My Boo-Boo, just went and looked It's a 3 1/2 " vise with a 2 inch opening Sorry !

Jason, Very effective way of preserving our steam heritage, all from solid.....,I Love it. Thanks for sharing , and the work ! Rich

Well, I just realized that Jason and Pat have posted a whole lot of information here and the technical research and drawings are awesome . I have been on another mission ( and still am) and need to come back to study the data. I agree with Jason that They are reffering to the two cylinders...

SO Rich, What are you talking about ? Air or Steam ? so for those unfamiliar with the differences, let me show you A big difference in steam engines is "cutoff" where the steam admission cycle is cut short (like 40 % ) which may be called " Lap" because the steam continues to expand and...

So I looked at Julius De Waals prints and even though they are Metric, he pretty much followed the Hedin drawing except he doubled the sizes ! I noticed he made the rods all the same ( large bores) but inserted brass bushings for the two different crank throws. He also has the steam valve...

As Paul Harvey (Famous radio broadcaster-1950-1980) use to say "And now for the rest of the story " But first , Thank you Pat and other followers for the information, and book references and all the comments . it is really appreciated ! I have the Live Steam issues from 1977 so was able to...

Thanks Jason, but that is not the model or plans he wants He needs the Hedin version if possible Thanks for the reference Rich

CORRECTION ! Simpson and Shipton drawings Sorry for my error in the title block Rich

Peter, Wonderful build and congrats on your progress ! Quick question as I may encounter the same thing--Metric to Imperial conversion When you redrew the engine to start, (1) did you draw it in metric and then let the CAD program do the conversion, or (2) did you convert the dimensions and...

A good friend of mine wants to make a model of the Simpson and Stockton rotary piston engine. This is not the drawings or model offered by Polly Engineering in the UK ( called "short stroke" ) and covered is a MEW issue years ago. Recently Juilius De Waal did a fabulous reproduction of the...

Sorry Graham for the delay, I have been deep into writing my "text" book on the Monitors engine and it is almost finished, and should be a great resource for those who have the drawing book and want more info on the designs . The engine would start at any point of rotation, so yes, there are no...

another trick to prevent breakage of small taps is to do it upside down. It uses gravity to clear chips , you can stop and the natural position of the tap wrench shows you where it should be, so you can tweek your way into the part using your thumb and forefinger.. Picture shows a 1.2 mm tap Rich

John I just found your post, so this is a bit late I am afraid, but to answer your question on a simple steam engine with a D valve , that is no lap or lead , the maximum eccentric throw is always 90 before the max crank throw point AND the eccentric max point leads the crank shaft in that...

Yes, the dedication,skill and commitment that Mark made should not be for naught. Cudo's to Dana and family for pursuing the project and completing Mark's work. As we all know, this is seldom found in our hobby and is much appreciated by all, especially with the skill level displayed by Mark. Rich

Let me address that particular question exactly and not infringe on Peters explanation. First --let me say that Ball Endmills are made far more accurate than any drill bit. Just look at the sharpening equipment used to produce the ball , not only correct diameter but a perfect spherical cutting...

Dana, My sincerest sympathies to you and all of Mark's family . He was an exceptional man, and it is quite apparent he would follow his heart and was unfazed when it came to new challenges . This is quite apparent with the many challenges he faced with this current project that he solved with...

Richard, your comment : Ho ho. So your instructors all know you and at opening day in Sept. they all say "Here comes that Carlstedt character. Don't look". Is more truth than you realize ! Ho Ho ! I use to be fairly proficient in AutoCad ( 95 and 2000) but stopped 20 years ago then tried...

Well I won't get into the plus and minus's of the many various CAD programs My suggestion is to check out local colleges and see if they have a senior or military discount. Our local tech college allows (62 age+) to enroll in "not filled" -open seat classes for far less ( a $ 200 class is $40...
