Re: Cast iron ate my drill

Its looking like Im done with the hard iron on the shay, knock on wood. Got the 6 holes for the door dogs drilled and tapped, and only broke one tap! Luckily was able to get the end out with a pair of pliers. Doing the file test on the firebox door and ring, looks like they are softer than the smoke...

Re: Cast iron ate my drill

Thanks for the tips! I'll get the skin off so the tap wont rub on it. I have no idea how hard the iron will be under the dogs so I guess I'll find out. Looking forward to being done with the smokebox door though, hopefully the firebox door iron is softer.

Re: Building the 2.5" Scale Shay

Time for another update! The delivery and exhaust lines are complete and work on the smokebox door is underway.

Re: Cast iron ate my drill

Behold, corner burner iron! The foundry that made these castings should patent it as a surefire way to destroy drill bits. I had to resharpen my long 1/8" drill about 12 times to get the hinge done. On the bright side, I have gotten pretty good at sharpening drill bits by hand.

Re: Cast iron ate my drill

Yeah, one of those things with castings, especially thin ones. Anyway, resharpened my bit and managed to get the holes done. It made chips like ductile iron but Im pretty sure its gray, so couldve gotten chilled at the foundry. Hopefully the inner part of the ring isnt as hard because Ill need to ta...

Re: Cast iron ate my drill

I’ll try my hand at resharpening the drill bit and going again. Just odd that the center drill went in like it was butter but the brand new drill bit burned up on the first try. Wasn’t a cheap bit either, I’ve stopped buying the cheapest stuff out there because stuff like this happens.

Cast iron ate my drill

While trying to machine the door ring for my smokebox, I've run into an odd snag. The cast iron burned up a brand new #19 drill bit after taking a #2 HSS center drill with no problems whatsoever. my 1/8" endmill and a #3 center drill also went in with no problems but as soon as I tried the #19, it s...

Re: SP NG Diesel #1 (GE 50T) - Triennial or Bust

In this hobby, traction is almost always the limit to what your locomotive can pull. The more grip you get, the better it will pull. #1 thing is to have all axles powered. Then you can add weight later if you think your locomotive has enough power to do so, and you want to pull more. I'll agree wit...

Re: Need some speed tips for getting a project done faster.

A good piece of advice I've been told is figure out when to be a brain surgeon and when to be a blacksmith. Not every part needs to be to a +/- 0.001 tolerance. Its taken me a while to break myself of wanting to be super precise on everything, but it does make a difference. Like most of the cosmetic...

Re: Super Scale Cylinder Cock Valve

I dont know of one off the shelf, but I think one of the AMES ball valves could be modified to work like an air tool shut off valve which should work just fine for operating cylinder cocks. With the ball in the on position, drill a hole through the body into the passage of the ball. Then rotate the ...

Re: Urgently Help needed concerning J 611

Sounds like the May trips they have scheduled are fundraisers to fund more maintenance for 611.

Re: Building the 2.5" Scale Shay

I'm pleased to hear that your Quick Weld worked. Yea! Remember to have fun re-timing the eccentrics. And Thanks to Pontiacguy1 for the added knowledge for LocTite pre-cleaning. Folks on this Board Rock! ~RN I did have fun, timing stephensons valve gear can be an interesting thought experiment. And ...
