GREAT boiler feed pump!
I ordered this boiler feed pump for the tender connected to a smaller live steam locomotive. I did order the machined version to save time. The kit came well boxed and with good instructions - took no less than thirty minutes to come together. A SMALL amount of filing was required, but you would expect that with materials so handcrafted and quality. 5 Stars all around!

Great little kit! This was my first time working from castings, and it went very smoothly. The trick with the little clevis pins is that they are under 1/8"...measure them with calipers and pick a wire gauge drill that's very close to their actual size. If you drill 1/8" holes for them, you'll have a VERY loose fit. Not a big issue as long as you know about it before you drill.

This is an excellent project for the beginning machinist. The kit is quite complete, and the drawing is excellent. After building one, I ordered another kit for my daughter to build.

Review
The PMR fully machined boiler feed pump kit is very easy to assemble. I would recommend it for several reasons. 1. A great way to supply water to PMR's boilers. 2. Makes pressure testing boilers a simple procedure. 3. Fills and supplies boiler water faster than I thought. 4. Acts as check valve between water supply and boiler 5. Has no problem pumping over 100psi. It could use shorter cotter pins, but nothing that wire cutters couldn't handle. Pictures via email of my steam plant are available at --> rcpilottoo@gmail.com
