General Discussion / Topland Diesel engines

Anyone have any info on these Topland engines?
Are there any in the USA, and can they be imported, 5hp?

General Discussion / Model RR
« on: April 01, 2026, 04:14:46 PM »
Bucket list. Didn't think it would ever happen, but with intrigue, a bit of drama, and level of sketchy-ness, (required because it's a Park Train) I've managed to acquire about 3600ft of 12lb rail. And a 1950's Tampa Metal Products Tom Thumb Streamliner "Diesel" in Santa Fe paint. I've also got a Minature Train Co G16 and 3 cars, (the Camp Bauman train). Now I want to (learn how to) build a Railroad. .....build a rail straightener, build a rail bender, etc, etc.  I'm excited.

Please throw your opinions here, of what a brand new Metro 6/1 (partly apart) would possibly be worth today......?
Looks unmolested and preserved well. Light weight spoke flywheels
TIA

General Discussion / 4 days in ICU
« on: November 24, 2022, 11:09:45 PM »

A heart attack does not always come as pain in your left arm. Mine was between my shoulders in my back. Last Thursday 11/17 After some time of denial, and increasing discomfort, I decided it was time to go to Urgent Care (they were closing and getting ready to lock the front doors) where they hooked up the wires and saw problems on the Electrocardiogram. An ambulance ride and 45 minutes later, I was at the hospital, in the Cath lab getting 2 stents installed (one artery 100% blocked) in an expedited fashion. Then 3 more stents installed yesterday, (another artery 90% blocked) 4 days in ICU total. Funny thing, that Thursday morning I was in the middle of no where picking up a cement mixer from Marketplace. I worked pretty hard getting it on the trailer and was worn out from using the come-along. Shortly after I got home with it, the discomfort started. Discomfort NOT pain. Pressure. Uncomfortable feeling, not pain. So very lucky it happened here at home. Doing much better now. One of the doctors said, 'With heart issues "Heart Attack pain" means any pain from your navel to your head, not just sharp pain in your left arm".

My message is, do not ignore it or brush it off.

Listeroid Engines / Forges DeGuilly....Horizontal Boring Machine
« on: July 22, 2022, 12:21:36 PM »
Well, seven years later.....and some effort to un-bury the machine from 'storage table' duty, the FDG is powered up and running. Incentive job was drilling and tapping the end of the crankshaft on a Wis-con V4.....
Heidenhain DRO install is next.....not sure when.....but next. Along with some other general maintenance and adjustments.

Changfa Engines / Chang-chai and ST head, deal? Or no deal?
« on: October 27, 2021, 11:13:01 PM »

It ain't pretty...
Found this, seller was asking $600 said he'd take $550. I saw it run, started right up with the electric starter.
He knows nothing about the ST head, wires are disconnected. Data tag is unreadable except for 2000 which may
be the year built. Is there a stamped model/ serial number someplace?

Worth the money?

Listeroid Engines / 6/1-8/1 650 VS 850 RPM and Iron VS Alu. pistons
« on: October 26, 2020, 03:55:22 PM »

I've seen the warnings "do not exceed 650 RPM with a cast iron piston", or "if you're intending to run 850 rpm, better have an aluminum piston fitted"....etc.
Could someone please explain this requirement in detail?
