Potty Finger Engine

By `ek Stew!

Gorgeous flywheel, & column.      That`s shaping up beautifully!  

I see you started 5 days ago, and I`ve only just seen it.......

Where have I been all this time?      Sometimes I worry about me! 

But, not for long!

Thanks:- Nick/Dean/Jack and Dave

Dean the indexer is just a simplified dividing head but a lot easyer to use, some Guys have made their own.

Hacked the base out today from some ally jig plate.



Then squared it up and mill around the edge with a 1/4" ball slot drill.



The roller bearing arrived to day from Hong Cong £6.50 for 10 including postage:- don't know how they do it 

So that I can fit in the crank pin they are only 7mm dia by 2.5 thick I was planning to assy 2 to the shaft but ended up assembling 3

Her's the assembly so far.



IIt runs nice and free, but with a slight wobble I intended to drill the fly wheel for the bearing with the next size down letter drill so that the bearing were a tight fit but when It came to do the job I forgot and ended up sticking a 7mm  drill through it resulting in a slack fit from the bearing so I had to glue them in place, that where the wobble came from I think.

And I'm not quite sure about the proportions of the base I may hack a bit more off it,

Have fun

Looking good Stew, I think you're going to have to incorporate a mirror in the final project just because you seem to enjoy using it so much though!!  I'm anxious to see how you set up the power arrangements, you've got your work cut out for you with those Greek columns leading the way mad jack

I hope that you realize than now you will never be able to make 2 of something and have us believe you. You will have to show us at least 4 if you want us to believe you. 

That engine is looking mighty fine though, on both sides!   

Cheers

Thanks Guys

This post is going to be a mirror free zone, just in case Jack posts a grusome hair cut picture in retaliation 

Finish with the ally work and on with the brass levers.

These were to be fabricated just like the column and silver soldered together the fluting was done in the same way on the indexer but using a 1/8" ball cutter, the lever was also squared up and the centres drilled in the indexer.





I used some square brass section and the rest of the bits were just simple turning jobs

Here's the trunnion being turned up



And her is the parts ready for silver soldering together





And these are the bits after soldering and a bit of time in the pickle and a rub down, I'm quite a messy silver solderer so I'm quite happy with the result



And how things are looking.




Have fun

This is looking very interesting Stew 


You don't half shift on some of these bits 



Looking forward to seeing it take shape.

The speed of build is an illusion Done with Mirrors:- 

I spend a lot of time thinking about how I'm going to do the job,    I like to get the method sorted in my head and the tooling and material together, before I start to cut metal.

Its what I use to do for a living and can't get out of the habit

Cheers

Not many pics for this post yes I know

 


But forgot to take my camera into the shop, and there wasn't anything really that interesting going on.

I finished off drilling the levers and made the bearing blocks and did quite a bit of fitting and fettling to get everything turning over.

So this is it I need to give the bearing blocks a bit of bling and give it all a polish just to finish it off but it works great so when its had its polish I'll post the obligatory Video.



Have fun

Ok you've seen the drawings you've followed the build now the Movie

That was a nice quickie build now I relay must get on an build that boiler for my Loco.

Have fun

Very nicely done Stew! 

Good looking. Well silenced. Multi directional. Zero carbon emissions....... Who could ask for more! 

Great stuff!

Nice job Stew. I think that's one of the prettiest finger engines I've ever seen. I realy like that flywhell.

Thanks again Guys:-

It was a nice little project with some interesting machining and I'm really pleased with the result, its sitting on the computer desk so that it can be gently spun whilst thinking.

I suppose it could be called a:- Thinking Engine 

Cheers
