This is a project that I have been working on for a couple of weekends now. This is a pump for a Preway No. 208. When I got it it had been gutted of all of its internals including the check valve, and a tire stem had been stuffed into the top of the pump. It had probably worked, and if not for us collectors would have been considered an adequate repair. So what is a stove /lantern collector with a nice little machine shop to do? Make parts. To start with it was nice to find out that Prentiss Wabers used normal threads (unlike our friends at other companies). This means no single point threading and normal taps and dies can used to make parts for these stoves. The body of the NRV was turned from 9/16 hex 360 brass. The internal part was made from 5/16 round 360 brass. The rubber pip was made from ¼ nitrile O ring stock. It is very important to note that this pip must be cut squarely and smoothly and sit in it holder squarely, or headaches will abound. The spring was purchased from the hardware store and cut and try method was used to get the right feel when the pump was operated. This part done it was time to make a piston and knob for the pump. These parts were made from 1018 steel and 6061 aluminum. I had no original pump to copy so I loosely copied a Coleman pump. The one to watch for on this stile pump is that the leather needs to float freely. This way when the pump is withdrawn air can run through the center of the leather. Then when the pump is pushed in the leather is sealed by the washer behind it. Originally this set up was made from two parts, a washer and a sleeve. I make this part in one piece for my stoves and lanterns where this set has been lost or corroded away. As for the aluminum knob, since I had no original to copy it was accentualy arts and crafts time. All I could do was make something I thought looked rite. There was more to go on the stove to get it going, but it does lite up and run as it should now. I don't think there is one of these in the gallery. So I will post it there as soon as it is ready. If any one has one of these stoves could you please take pictures of your pump handle with size reference and post it. Enjoy the pics Rick
rbhodges, This looks to be time well invested and a remarkable piece of work to restore something that once was useless! A fine demonstration of craftsmanship that approaches artwork right down to the knurling on the pump knob! Outstanding work! Chef
While I'm not able to follow everything you did, I got the general drift and am impressed by the final product.
Excellent work! Fearless fettling at it's best. You can download your award here: Fearless Fettling Award
I am always honored when Gary gives me a compliment. I actually have gotten quite a few from him. He is a gentleman and in my opinion, one that would know if and when to honor another master fettler. So, take Gary's award and display it proudly. Maybe make it your avatar. Ken in NC
Thanks for all the nice feedback. This has been a fun stove to work on. Preway made nice stuff, and they are pleasure to fettle. This stove is working now, and since it's still in its original paint it will only get a clean up. Thanks Rick
Hello Rick It is such a good restoration. You say that you intended making parts using your skill and your machinery. You have certainly succeeded. I love that wonderfully crafted NRV turned from hexagonal brass - a work of art and a great idea.
Evening, Rick, EXCELLENT fettle solution, and very well accomplished!! HUZZAH! Thanks for sharing your success! Take care, and God Bless! Every Good Wish, Doc
