can't believe I did that...

This is an iron crankshaft casting for a PMR #1. I realized as I left the bandsaw that I seem to have hit a snag.

I can just imagine your face when you looked at it and realized what you'd done!

aonemarine · Nov 22, 2014

Looks like something I would have done.....

Swifty · Nov 22, 2014

Can you use a pin in its place.

Ouch!
Same as aonemarine, looks like something I'd do!

I hope to do just that! I have some 3/8" drill rod that should do fine.

Just build it with a really short stroke..

bar stock to the rescue.

When I did my PMR #5 it came with a similar crankshaft casting. I looked at it then the drawing and told myself to forget about it. Given it's length I didn't think I'd have a chance in hell getting that thing machined without bowing, chatter, etc.

I didn't even try. I just made it out of barstock and welded the components together.

Thats almost as bad as working overtime to finish breakdown parts, and then the foreman says "which ones have the tapped holes?":fan: Made all clearance holes. Parts still worked.:wall:

looks like the crank wont have much throw ! Don't fret, the next will have more is my bet. I've done it !

Believe it or not it took me a few glances to figure out what was wrong.

So I could have easilly done that myself.

I started to make the exact same mistake, but realized it just as the blade started to cut. On the bright side, it was a good clean cut! Seriously though, I contemplated making mine from scratch and it may have been easier than using the casting. Show us the built up one when you finish.

Probably the best thing you ever did with a PM casting. Make it up from barstock or cut it compeletly in half and use a dowel pin. Not the worst mistake ever made (by a long shot!)

can't believe I did that...
