Re: Prototype: why diesel-electric over diesel-hydraulic?

Weren't the early day electrics also DC variable speed motors? Capable of a wide speed/operating range under load. I don't remember hydrolic drives having that much range- although now I suppose anything is possible. I've often thought an electric variable speed hydrolic drive would be idea for hobb...

Re: WTB: 6" spoked wheels for 3" scale tender

Thanks all, with Charlie's help, have made up a pattern duplicating my existing pony truck wheels and now preparing to have them cast up for wheel sets for the tender and rolling stock.

Re: Surface grinding machine

Hi all, thanks for the advise and leads on equipment. Thankfully the fever broke early so i didn't spend all my retirement the same day. Still looking however, and will wait for the right deal on a good machine. Several in Portland and one in Spokane look interesting, even though a bit spendy for my...

Re: Milling performance using slower RPMs

Don't work with aluminum much, so Iam no expert here. But my old instructor in lathe class used to say: if it's making noise, your going to fast - or the tooling is dull. Quite often it's both I think... Could be the different condition of each end mill accounted for the variability you are seeing i...

Surface grinding machine

So I've suddenly realized I simply can't live another moment without a surface grinding machine. Why I've managed all these years without one is - confusing, to say the least. After my epiphany, Of course I discovered there aren't any for sale here in the Pacific Northwest. Anyone have recommendatio...

Re: Are old old chucks any good? Or, what can possibly go wr

Perhaps I used the term 'backlash' incorrectly, or perhaps mis interpreted the excessive play and binding/rough action in the lead screw as a backlash problem. In the first instance my grizzly bench mill (20 years old now) started having serious side action in the table recently, including developin...

Re: Are old old chucks any good? Or, what can possibly go wr

Indeed! The more I clean up and properly oil the lathe, the better it works! Took apart the cross slide assembly over the weekend and removed a phenomenal amount of old shavings and gray-black crud. Also took out the gib and cleaned the old dried gunk and scrubbed some old rust spots off. After lubr...

Re: Running copper, installing new outlets

All the major welding vendors provide input amperage on their web sites for their welders. You can check out what your preferred machine amperage requirements are, then go 15 or 20% over that to the next size up to determine the size of your welding circuit. Electrical supply houses can also help yo...

Re: Are old old chucks any good? Or, what can possibly go wr

So, I have found out what actually can go wrong with a chuck., at least a four jaw 10" Pratt Bernard that I bought with the lathe and forgot about! I threw a cardboard box with some junk in it on top 6 months ago and just found it again! pleasant surprise when I cleaned up the shop the other day. Th...

Re: L.E. American & tractive effort?

Nice looking engine on your web site. If it's any consolation, the prototype 4-4-0 Americans were often known for having poor traction and being 'slippery' , largely due to their very large diameter drivers. ( they also ran out steam in the early days because of to large steam chests and values for ...

Re: Name of our "Scale"

Actually, "Park Gauge" is what 12" -24" gauge trains often are called. With 18" to 36" gauge being classed Narrow Guage If the railroad is in service as a public carrier. So maybe there is some overlap in gauge and scale at the upper end of the park Guage market.... Certainly wouldn't be railroading...

Re: What size is your compound rest?

Thanks to DrDavao i acquired an almost new Grizzly compound, which will work I think. Turns out it's a bit small for the build of the lathe, so I will be making a new lower half with dovetail to fit the upper compound assembly. (My bolt circle diameter is a full 1" wider in diameter than anything ou...
