I'll be watching along. I remember how stressful the crank was for me.

Love the layout dye, what do you use? I've always had trouble finding any over here.

Finally got some time to make bit of progress on the peewee

The crankshaft is almost finished just need to thread the end



Happy so far with the way it has turned out

 

[michael-au]

Ready for threading, I don't have a 3/16" die will have to get one tomorrow

Hi Mike.

The latest post on crankshaft turning is very educational for me. I have shying away from turning one piece crankshaft from fear of failure. Looking forward to make the PeeWee 4 sometime later.

Thanks Gus
It is nerve racking, but feels good once it is finished

Put the thread on the end of the shaft today

There is a 10 deg tapper on the front of the flywheel, hard to see in the picture

Back turned out for the nut to hold it on

Fixture turned up to hold the flywheel so it can be turned to the correct shape

Crank looks great and I'll be really interested in how you make the flywheel, still yet to do that. Many things have got in the way of my build but I'm hoping to get a bit more done soon.

Edit: Cross post...I see you're already well on the way to finishing the flywheel.

Brings back memories. Your doing a great job.

Thank you Cogsy

Thank you Steve

I have seen your peewee and pacifier thread
I look at them a lot for inspiration and learn how to do things, very informative

 

[michael-au]

Finished off the flywheel today

Cheated and used CNC

 

[michael-au]

I hate it when the photo's end up sideways

 

[michael-au]

Started to machine the camshaft

Cam was my favorite part to make.

Cam was my favorite part to make.

I think the cam and crankshaft are 2 parts that give satisfaction when they are finished

I will need the modify the ends of my cam, The bearings supplied by Dirk both have an ID of .186, shouldn't be a problem I hope

On the rear the gear should be a press fit and then the cam goes back to the lathe to modify the gear to accept the bearing with a press fit. The id of the bearing should be about .001 smaller than the shaft. I think the rear bearing should be .250 x .625

Hi Michael

Your coming along nicely, you should be finished soon.
I have made numerous parts while here offshore Vietnam, I will post some pics once I get home, internet out here is to poor for uploading pictures.
Your parts are looking great, where did you purchase your gears?
I was going to get mine from WM Berg as per the drawings but they require a minimum $300 order
