Giving it the finger!

[divided he ad]

Well, the finger engine anywho 

This is a mirrored post I've written up on another forum, sorry if you're seeing it twice. Just thought it was about time I put something on here! 

Wasn't sure where to put this as it's using someone's measurements and my mind to create it..... If it needs moving I'm sure the powers that be will sort it? 






Got a little bored over the Easter break. So thought I'd tidy up the workshop a bit.... That lead me to find a little plan for the NAMES finger engine I've had in a draw for 4 or so years!

Never made it, thought that it looked like a little fun "weekend" project so.....Stuff the tidy up! 

 Here is where I'm upto after 16 ish hours.... I just can't follow a plan   

Warning, this gets artsy fartsy   


Started with this... Converted to metric and rough materials cut.




Then start to put the holes in all the right places. First the upright.






A little shaping with the ball turner.







Polished up a little and the micro ball bearings pressed in.





The treadle.

Put the holes in the correct places...


And make it a shape you like the look of.



I used a carbide burr for this bit... Reason being the endmills seem to be a little too grabby in my experience...
You can't let go of this, else there will be a big bang and a few tears!!!   :bugeye:




Then the conrod.

Similar use of a burr, 1/8th one this time.... Bends a bit,  very small cuts are ok though..




Then make a wooden erm,,, fixture!?


And shape the rod a little..





The cam,


A little narrow!






Think that'll do for now,

There are quite a few more pic's but they're mostly just different angles etc.... Figure you've probably had quite enough pic's in this post by now 


 I'll hopefully get a little time on the "dreaded flywheel" this weekend?

Dunno why I think cutting these flywheels is so damn tough... Maybe it's because I have to stick to the plan      



Possibly more over the weekend?

I'm liking it Ralph.  I will be following.  This is something I think I would like to build.
Keep the pictures coming, can't have too many.

Looks great so far...I like the creative touches too!!

Nice touch Ralph, I do like the added touch to the column. I will be following with interest.

Good start, looking forward to seeing more of this little engine

Thanks folks 




Glad you like it so far, I will do my best to get it finished reasonably quickly.

Might need some of this        I have a little engine in a draw that is now pushing it's 3rd birthday and is still not finished!

Sometimes inspiration avoids me and I just can't come up with anything I like! As soon as the flywheel starts to talk to me I'm going to get going.... Probably make the base first while I think about it?

Hey , I completed the first part of my R&B in December 1996. Hopefully this weekend it might have an ignition system fitted  then all that remains is to get it running.

No I think there may still be a couple more bits and pieces

Sure it wasn't your visit on to me on Sunday that shamed you into making a post on here, you must know you have been a member on here since it almost first started, maybe you were getting a little guilty.

BTW, why not show them that fantastic little torch you showed me when you called, and don't keep such wonderful little things such a secret.

Another BTW, just to the other members who haven't come across Ralph before, he is a master at using a ball turner for decorative effects.

I am almost finished with a Stuart No 9 I acquired 30+ years ago!! I see no need to rush anything (obviously.)

Hi Ralph,
             I recon that when you read my reply to your post of this item, over on MM, I will be off your visiting list

forever.    Grand job. as usual.

Cheers Dek.

   1996!!!   30+ years!!!  Wow! Some people really aren't in a rush are they?    
 Well, good luck on the finishing stages both.... I look forward to seeing them..... In a few years time 

Sure it wasn't your visit on to me on Sunday that shamed you into making a post on here,

Erm.... Yep.

you must know you have been a member on here since it almost first started, maybe you were getting a little guilty.

And yep again 

Little torch ain't an engine! Figured the site was for engines and tooling    You tell me where to stick it and I'll give it a go! 

Another BTW, just to the other members who haven't come across Ralph before, he is a master at using a ball turner for decorative effects.

Well, I do my best 




Dek.... There will be words to be had about this flywheel!!   

Fancy laying down a challenge like that     Now I'm going to have to give it some thought 

Maybe make another cause I will need to bore the main upright and cross drill to get the positive wire through.... Ahh well, another on the list 

(gonna need more bearings!)



More later...

Got to get ready for work now





Ralph.

[Deko]

Plenty more bearings where they came from Ralph, so you can't use that as an excuse. 

Where to stick it !!!!!!  ODDBALL of course, where all my stuff is. 

Cheers Dek.   < spot on eh?

[divided he ad]

Odd ball eh? I'll take a look later.

I've yet to get the full gist of the site... But if you    guys can do it I should be fine 

Spot on indeed 


They need one on a mobility scooter now 


Right, tea first. Then see if Inspiration can give me a big whack upside the bonce  ..... Need to get a flywheel sorted 






Ralph.

[Bogstandard]

Now then Ralph, you should know that I hardly use mine now.

I was thinking of a smiley for Dek John... I know you've become rather spritely 

I'll get to the oddball bit soon enough, been a little busy today 


Speaking of which....



I was trying to think of a design for my flywheel and stumbled on the design for the base instead    Just the way the mind works!

So, I was gifted a few stainless circles by this guy    last time I visited 

I was thinking of using a 6mm thick disc but the lever would stick out and that just wouldn't do. So I selected one of the larger 3mm thick discs that would allow the lever to lie within the diameter 

I mounted it on an arbour and cleaned it up using emery and a little polish... This stuff is tough!! No pic's cause it was quick and basic (and I forgot!)

I decided to have another go at engine turning, last time I tried was on my MkII finger engine. It was ok but some swirls dragged a bit.

Anyway, enough talk more pic's eh 


I used the rotary table to hold the disc on an arbour and used 30' for the inner circle and 10' for the outer. I had to go over them twice to get the full circle cause the stainless is so hard. Took a while but I like the result 










Then I needed a cover for the bit left in the centre where the washer was. I used an old little brass flywheel blank from the bits draw.
I drilled it to allow the M10 thread to pass through. Then turned a spigot to locate it in the base disc.



Then turned it around and bored the recess for the column to fit into.


I needed a way to hold this for shaping so I turned the hex off a M10 bolt and cut a slot in it so I could tighten it.



Then began shaping the part.




Then I added the fancy bit to it 






So this is where I ended up at about 10PM





At some point I'm going to sort the flywheel out.... At least I have an idea to try to make now 




More as soon as I can.




Ralph.
