Well another slightly productive evening in my little shop of..... creativity! ;D

I spent at least an hour just figuring out my con' rod and crank lengths...( 7.0mm between crank centres and 53.5mm for the con' rod!) this one had better work! ::)

I posted some new pics in the 'bucket' so feel free to nose :D

(New photo's headed in lower case... sorry for all that shouting!!)
 
Looking good Ralph,

I really do admire your curves (on the engine that is).

John
 
Bit close to the wire there john!!! :big:

Thanks, will see what the think box dreams up for the rest?! ;D
 
Well I have realised that I should try to keep everything in the one post (took some time to figure out!! ;D )
So that said just a little update on this evenings work... Crank shaft, not very big but took a little time to create! (nearly 3 hrs!) Said I was concentrating on this one!
I being the slow ass genius I am (self proclaimed!! ;D) just figured out how to stick a photo or two here.... little large but hey, it's a start!!

It had better work after all this!

Ralph. ::)


 
Ralph,

I really like the style of your engine. :bow: good job.


Eric
 
Ralph,
I explained how to do it in my little bit on posting.
The piccy size is perfect, and the engine bits are as well.

John
 
Thank you both, and sorry I didn't absorb it all john...I will re-visit and read over :) must have been because I was so anxious to post anything!!
Speaking of posts... still very interested in your turbine... love to see how things develope ;D

Eric, I don't seem to be able to see any of your work in progress.... not too busy with web control and a few drawings are u? :)
Would be nice to see some of your work too ;D


Ralph.
 
What a great series of pix ! :bow: :bow: :bow: :bow:

Never occurred to me as a somewhat noob to use a rotating base on the tool post to get those great curves !!

Love your blinging up the finger engine !!

Mike
 
Much appreciated Mike ;D

If you look in the tips n tricks section there is a link to the 'Steve Bedair' 9x20 lathe site I found the plans on... there is some other cool stuff there too.

Thanks, Ralph.
 
Hi, just got a running mock up (80-85%complete) so thought I would share... made a little 'tube' vid (load of stills and a little running movie... very little!) and will paste the url at the bottom.

A small disclaimer first... I managed to get a few things finalised this evening but totally buggered up my flywheel... not the styling as such just managed to hit the grub screw drilling's on the 'good' side!!! dumb I know, but you do this sort of thing in the experimental stages (no plans u see!!) Anyway basically keep in mind the flywheel will be renewed.

Your reactions good or otherwise happily read :)

Ralph.

Very nice looking engine! I like this one the best as far as the treadle engines go:eek:) I am going to have to build one of those, so I'll have one to play with:eek:) Again, Great job!

Wes
 
Thank you both ;D

Once it all works I'll post the pivot point measurements and then all the styling is down to the individual!

I think I am making this a lot more complex than it should be! But it certainly is a learning curve!! ::)

I think it is time to get it finished, I'll try for next week....

Ralph.
 
Luv' it Ralph! I like that you are creating art/machinery with esthetics as the most important part of your vision.

Having said that, we gotta do something with the flywheel! ;D No offense intended but it just doesn't match the stunning work you've done on the rest of the engine. If I may, let me suggest something. I've had this idea for quite a while but it looks like recent changes in my work life are going to cut into my shop time and prevent me from trying this anytime soon.

I made a flywheel for my little finger engine from individual components, ie: separate hub, 8 spokes and an outer rim. The indexed holes were drilled/reamed in a spin indexer.

Now imagine that same method taken a little further. The hub could be indexed and drilled and while still part of a longer piece of stock, then chucked in the lathe and turned round with a ball-turner. The rim blank could be indexed and drilled, then chucked in the lathe and rounded on the inner and outer edges to make it round as well, ie: a torus. http://en.wikipedia.org/wiki/Torus

Once assembled and installed, the rounded flywheel look would really complement all the beautiful curves you've built into your engine, no? :)

Cheers,
Milton
 
Hi Milton, I know exactly what you mean... it is my current ability level that limit's me! :(
Also I have still to purchase a chuck mount for my rotary table... spent a lot on machinery in the last year and I still haven't built my house! So you see I have current restrictions on the indexing! Not to mention I need to locate some larger material for the flywheel anyway ( I think it needs to be a little larger!)

I love your thoughts though... I did make the flywheel convex and intented to round the outer edge, but as I said earlier my machining went wrong and screwed the whole thing up anyway!

I will keep your idea's in mind :) ....You gotta have shop time Milton ... stress relief is all important!! Hopefully you will find some time and be able to try one for yourself? :)

So happy that others are taking an interest in my design ;D


Ralph.

P.S. Have you got any pics of your finger engine? Would be nice to see ;D
 
Can you show a video on how to use the ball turner to make a ball?

Thanks for asking Ralph, here's a link to a previous post about my engine/generator. http://www.homemodelenginemachinist.com/index.php?topic=877.0

I'm glad you didn't take offense to my flywheel suggestion.:) That's what I like about this group. It's a friendly, good spirited bunch of fellers.

Ralph... I second this. Any chance on doing a video? would love to see it in action.

Eric
 
Yes to both John and Eric, I took a break from the engine this afternoon so I can sort that kind of thing out, just finished the build on a camera holder to mount to my lathe or mill.
Designed in my head this afternoon for the very reason you ask... demo's for to be placed on the 'tube' ;D
Just got to make a perspex shield and I'll throw a few balls out (mmm! maybe need to re-phrase that?!) and post them in with the post I started in tips 'n' tricks.


What do you think? ;D

Ralph.

P.S. more photo's etc in the lathe mods section ;D
 
Right! Here we go again ;D

After a full workshop revamp I finally got started on my treadle engine again :D

First up is the new fly wheel. Not finished yet but this is a section for work in progress !

After much thought into a new, unseen to me design I came up with the concept of a laminate flywheel.

3 sheets of steel and 2 of brass. Soldered together and machined as one... took a little more planning than just that but it seems to have worked!

What do you think to this one Milton?

P.S. Eric you were right about the workshop.... What a mess it's in now!! :big:
