Re: Broken Drill Removal

It works! The alum in hot water did an excellent job of removing two broken 3/64" drills stuck in the brass cab door of my NYC&HR 999 project. The door is 1/4" thick x aprox. 2" wide x aprox 7" long. I broke two 0-80 tap drills for one of the doll house hinges I using to attach the door. I put about...

Re: Broken Drill Removal

Thanks for the tips. I knew that it there was anybody who knew about removing broken taps or drills it would be the Chaski bunch. Ha! Ha! Anyway I'll try the alum technique. I wonder if layout dye would be a viable barrier to the alum solution to prevent discoloration.

Broken Drill Removal

Does anyone have an idea on how to remove a 3/64" diameter drill tip, about 1/8" long, from 360 brass? Or a shop that can do it? There are shops around here that offer spark erosion removal services. But, they only go down to 1/8" diameter or a #5 screw.

Re: Sharp Corners

Pretty cool. I wonder if it would be worth the trouble in the future to make a mold and cast those braces. It seems you had to go through quite a bit of work to get to the finished product. Once I figured out the milling of the "V" slot to form the bend it took about two hours to make each corner b...

Sharp Corners

Here's a technique that some of you may find useful: For my NYC & HR 999 project I had to make corner braces for the cab walls. Luckily about 85% of the original 1893 drawings exist so, in this case, details of the braces are available. The original braces were an iron casting 1/2" thick that tightl...

Re: Disney American

Ah-ha, now I get it. The O-ring is on the poppet. I had thought it was nested in the body. Thank you Jack for the sketch. Jack ( or anyone): Any preference on the O-ring material. Per McMaster-Carr in steam silicon is poor, Buna-N and Viton are not recommended. EPDM is good and Teflon rated excellen...

Re: Disney American

My compliments on your beautiful locomotive. I'm interested in one of your 1870s Westinghouse brake valves. When do you think they would be available? Is a drawing or photo or dimensional information available? Also, I've read and reread you description of your boiler check and am too thick to under...

Re: How to build a 4" Case traction engine Book

Is the book a compilation of the Live Steam magazine construction series or is it something in addition?

Thanks, Dave

Re: 1.5 " scale working snifter valves

What are the attaching threads? Can the attaching threads be 5/16" - 27 MTP? What is the outside finish?

Thanks, Dave

Re: Boiler Lagging Joint

My Ten Wheeler has horizontal joints in the jacketing because I could not get the blued stove pipe large enough. So I made simple 1-fold joints that hook together, just under the hand rails. The upper joint overlaps the lower one to keep water out of the joint. Each course of jacket is clamped at t...

Boiler Lagging Joint

I have noticed in several steam locomotive pkoto what appears to be a horizontal seam or joint in the boiler lagging. The seam or joint seems to be most prominent on pre 1900 locomotives when Russian iron is used for the lagging. Case in point is the NYC&HR 999 of 1893 that I am modeling. Note in th...
