A snappy comeback is in order, however I will pass, this time, Dick, I mean Allan.

Nice work, the standing double is pretty neat. Shoot me an email at jussmitty@yahoo.com I'd like to talk with ya. Smitty

Telling nobody to critique is like telling them "I'm sensitive and you might hurt my feelings"

A old biker used to tell me, if you got your feelings hurt, ya shouldn't have brought them wit-cha.

HA.. Toys look like fun. I was wanting a steam engine to run my old flat belt B&S drill. Imagine the "Yuppies" face as it went choo-choo choo.. as it drilled a hole? Even if it ran on air.. lotsa fun.. Shock attack.

David, David, David, you just dont understand.......check out this thread.

Cool! I love making little engines like that. I have lots of source of plans (look in the archives, keywords Elmer, Duclos, and Ed Warren.

Pretty nice but I don't understand the wood. http://bbs.homeshopmachinist.net//biggrin.gif

But really my wife gets up early and stokes the woodburner b4 going to work so she dosnt want to walk through the mud/snow in the dark so we brought a load in the shop.

David, you could convert a 3-1/2 B & S lawnmower engine to run your drill press by converting it to a "bash valve" admission through the spark plug hole and uni-flow exhaust. Better yet, a two cycle Jacobsen (sp?) engine.

Here's a similar motor I did up some time ago using the same principle. It uses an old disc drive motor as it's flywheel and generator. I cut the slot in the cylinder to allow the wrist pin somewhere to go while keeping the piston shorter and better supported in the cylinder. This one has it's valve on the pin that the cylinder pivots on. Pain in the butt to make that part, but it runs and doesn't bypass too much pressure. It will just barely turn over on lung power, but runs up to speed on a bicycle pump. Vibrates like crazy too.

Great Job! The only one thing I can nitpik about is that they were all built in only one weekend. http://bbs.homeshopmachinist.net//wink.gif It took me about 2 months (in between jobs) to complete my latest creation. The "Poppin" vacuum engine.

Pretty neato...I've been meanin to do up a few for quite some time, just haven't gotten around to it yet. Seems that cleaning the garage is always more important.

As far as a critique, I thought the whole point of this forum was to exchange ideas and experiences...sometimes people bring great things to the table....sometimes they piss you off. It's what you risk by posting pics or ideas here.


02-15-2005, 10:32 PM
one weekend! too cool. I bet I could get (and keep) my wife interested in making one of those. just to have something new for when the nieces, nephews come over.


02-15-2005, 11:31 PM
thats a real nice coke can, well made, looks professionaly built too.
ha! ony pulling yer pisser,,well done on them little engines, BRILLIANT!

Geeze are you still pissed about my comment? It was not meant as a put down - it was meant to be encouragement to take the time to make a better tool - when it comes down to it we all appreciate an effecient well made tool - I just thought that considering your obvious talents you could have done a lot better than just welding the damn thing on. Besides - I acknowledge your idea of modifying the tool block as a good idea - I was disappointed in how you did not.

There are times when doing it the fast dirty way are acceptable (like when your life hangs on it and you don't have the time to waste), mangling an expensive toolholder maliciously is not one of them - you screwed up on a great idea and buggered a once good looking tool.

Hence the good idea - bad implemntation comment. I am not going to encourage mediocrity and you should not either as a machinist.

A couple of air driven "wigglers", My first and forth machining projects. Lots of fun to build and run. But I need some more plans or drawing for some more!! (any Help?)

THRUD,THRUD,THRUD, I guess my point was you didnt know what you were talking about when you said I should have cut a groove and drilled and taped holes to hold it on the other tool.It was mentioned that there is no room,A real machinist would have known that,I did and I don't claim to be a machinist,a machine hobbyist at best.I just have fun, and as far as ruining a expensive tool,it was $25 on ebay.

02-16-2005, 02:50 AM
Frank. actually the steel one was done a year ago it took about a wkend itself as I ground all of it on a surface grinder.

I made a hot air engine or 2 but never got them running, I was useing internet plans,you wouldn't have a copy of the popper plans would you?

Iowolf, I was under the impression ( illusion ?) that to "critique" could be either positive or negative.

I shall respect your wishes however.....
So...... no comment. http://bbs.homeshopmachinist.net//biggrin.gif http://bbs.homeshopmachinist.net//biggrin.gif

Loads of drawings and ideas here. This is just the first group,they go from 1 through to 4.Just change the 1 to a 4.


All the drawings are in the files sections

IOWolf: HOWWWWLLLLLLL (Timbersheperds or real Wolves?)

Yeah, I once posted these pictures of "HOW I mounted everything inside my cnc mill" I had just pulled in the wire, hooked it up and got it running again. Not tied down or straightened all the lil crooked wires going into the terminal strip.
I explained "why" I mounted the sensitive electronics away from the noisy 3ph and other load carrying inductors. A lot of educated thought went into my machine revision.

"I got hammered too". SO much I deleted the pictures and Let the people wanting to do likewise "figure out what I have learned in 30 years of electrical work". I think my feelings got hurt. In about 30 years or so of doing electrical work you learn a few tricks.

I am a amatuer machinist tho I am a excellent electrician. I am also a poor carpenter (don't have the desire to learn), but have to do that too. Here lately a lot.

I have tried to help others thou, including the ones I had resentment against. What is that old saying? What would Jesus do? I sure can't compare to him in forgiveness. I am just a old biker with a bad concience.

Some of the cars/bikes I have done have been bought by people before the shiny paint got laid on too. Ohh well, it has been fun and made me more than a nickel or I wouldn't have sold.

I thought about building a "air motor" from a old auto piston freon compressor.
Anybody got any plans or knowledge I won't Have to figure out on my own?

IO, The plans are from the November 1980 Live Steam Magazine. The plan are available as reprints through Village Press. The picture shown was my second attempt at this engine. I first tried to build it about 20 years ago, but it would not work properly. Too much substitution of materials, etc. I have to thank "bobs" from this board for lighting the fire to try this project again. I am getting into these flame licker type engines lately. Any other info on other plans/designs would be appreciated.


02-18-2005, 12:04 AM
Allan, Thanks for the web site on Elmers_Engines! Lots of info. I'll be months digesting all the information there! Elmer would have been some to know for sure!!
Thanks again

I prefer to hear constructive criticism, I only want to be able to do the best I can possibly do. I dunno, I made the deans list last semester, I think machining in general has changed my attitude on most things in life.
A lot of nice oscillators on here, and nice one too Polski.
