Re: Repowering SB 9" Lathe

Then all is well! The lack of 3-phase in much of the US is so odd to me. Europeans think of the US as the land of big power. I even had 3-phase in my house in a village in India. I have 3-phase on my houseboat in Amsterdam. It's the land of big power IF you spend big money. The utility wanted $40,0...

Sound Bend 9" lathe, MT-3 to ER-40?

I'm looking at some of the MT-3 to ER-40 collet adapters for the spindle of my SB9 as a solution to fit 1" collets, anyone tried this? I need to work with axles which I will be turning to a 1" diameter with a shoulder, then flipping them around and putting that 1" diameter into a collet and a live c...

Re: Breaking Small Drill Bits

#51 is a .067" diameter drill, and if you're careful and have quality bits they shouldn't be that hard to work with. You haven't had fun until you're drilling holes for grab irons in HO scale rolling stock lol! Carbide is too brittle at that diameter. I'd only use those if I was working in a mill wi...

Re: 12" working railroad

Another wheel set done tonight, and I decided to try fitting them to the truck. All was going well until I went to tighten the pillow block bolts and they are a little too long, just snug against the face of each wheel ugh. So I need some bolts about 1/8 shorter. As for the flange radius, I found my...

Re: 12" working railroad

Ryan, I missed that part about the outside edge. Don’t know why the IBLS is .125. Unless they anticipate some outside edge contact with guard rails or frogs, etc. I’d probably increase the radius a bit more just for GP, and ease of handling on the fingers etc, when man handling the wheels and cars ...

Re: 12" working railroad

Glenn, it matches the rounded edge of the flat bar I have for my rails. If I was to visit your track for example, with 12# rail and a larger radius I might find I'll hunt a little but I don't think any harm would be done otherwise. The other radius I was referring to was the outside corners of the f...

Re: 12" working railroad

Got the new bits home and played with grinding some profiles to get a nice finish, and loaded all 3 tool holders to cut each side of the flange and wheel taper. After fiddling around a bit with the setup I got one wheel set all done. I ended up doing an 8* angle on the flange which brought the "poin...

Re: Repowering SB 9" Lathe

We lack 3-phase power here except in industrial areas unfortunately. The first machine shop I worked in had a giant inverter because it wasn't even available there. The lathe is working good and I've done a little test cutting and then chucked up a wheelset and started cutting some tapers. It's cert...

Re: Your favorite low investment/high payoff tools and gadgets

My favorites: A "TICN" coated step drill bit, whirly-gig de-burring tool, and a $28 set of 8" calipers that I scribe with all the time.

Re: Looking for rail

I think you could probably find someone overseas somewhere else would make it, but they'd likely want you to order a very large quantity. I'd use it for a yard track, siding, or spur and make some adapter joiners, as commonly done in full scale trains.

Re: 12" working railroad

Glenn, yes those were the tools I forgot at work, I ground some with a nice radius for that flange root. The cutting I did tonight I had to cut short so I have meat left to cut that radius. Because the gage essentially becomes a measuring point in space, I’m cutting the 3 degree angle first and faci...
