2.5" Gauge Green Arrow Build

[stevendavis]

Here's the parts for the lubricator so far. I still need to make the arm and ratchet pawls. I tested the assembly and it does pump oil. I will probably make a new check valve, as I didn't leave enough room for the fitting nut under the tank.

Had some time over the last few weeks to get more done on the Lubricator. I used a print from the Rob Roy book to make the pals, and filed them to shape. I need to look for some smaller springs for it, as the ones I have on it now are a bit bulky. Though it is working ok. Still need to make a lid of some kind and add the mounting flange.

Very interesting little ratchet mechanism! 

And your pawls came out great!

Had some time to get a little work done on the Green Arrow. Got the crank pins hardened and locktited in. Wheels painted and one side of the axles locktited in. Still need to quarter the wheels.

[stevendavis]

Plugged some numbers into Cad and this is what I think is right. The bottom line is my carrage surface on the lathe. I'll be quartering on the lathe between centers.

Those wheels look great when assembled

Thanks Paul.

So, based on the drawing you attached, your quartering is actually thirding? 120 degrees?

And why are they all set to 120?  Why is one 126 and one 114 degrees?

Very interesting,
Kim

[stevendavis]

Yes, the center cylinder is at a 6* down angle compared to the outer cylinders. From what I understand that angle makes it necessary to clock the wheels at 120, 126, and 114. If I'm wrong on that, I hope someone will chime in.

[Kim]

Ah!  Makes sense!  Excellent explanation, thank you!

I've been hesitant to do the wheel quartering, but I got it done. Hope it's all good.
