Looks like small flies. They may have been attracted by the water or the shade on a hot summer day I guess.
If there was any water in the tender, they are probably mosquitos or mosquito larvae.

Re: OMG, Kamikaze bugs!

Heard an interesting/scary story about a locomotive on a sugar cane plantation in Louisiana many years ago. These railroads were seasonal operations, usually operating only from October to January during the harvest (grinding season). When they fired up their forney at the beginning of the season, t...

Re: Brushless Motor Controller

I need to replace the current motor b/c the rpm is way too high, and the motor is too small in wattage. I have read about the advantages of brushless motors (high starting torque, efficiency, etc.) and want to consider using one. But, I don’t know much about the electronics. I could go with another ...

Re: Brushless Motor Controller

John or WJH,
Do you have a suggestion for a better source than electricscooterparts.com? I’m looking for something in the range of 500-750 watts and 2000-4000 rpm.

Re: Brushless Motor Controller

I haven't bought a new controller (yet), and don't think the one I have will work with a brushless motor. The motors I'm considering are from electricscooterparts.com. Their web site says the controller is built into the motor. It also says the controller will work with any 5K pot, so this answers p...

Brushless Motor Controller

I am thinking about replacing the motor and controller on my 24v battery electric loco (permanent magnet motor and Curtis controller). The brushless motors (essentially a three phase motor per my understanding) come with their own controller. On the current setup, the motor and Curtis controller are...

Re: Pre heating boiler water

Maybe something like this, upstream from the check valve into the boiler: https://www.amazon.com/Taco-400-4-8-Inch-NPT-Float-Hy-Vent/dp/B003QSJLL2/ref=pd_cp_60_1?pf_rd_m=ATVPDKIKX0DER&pf_rd_p=ef4dc990-a9ca-4945-ae0b-f8d549198ed6&pf_rd_r=0R2MPBZQ2W36P1B4MH4Y&pd_rd_wg=j3RJk&pf_rd_s=desktop-dp-sims&pf_...

Re: Pre heating boiler water

One potential benefit of preheating the water before it goes into the boiler would be to drive out the dissolved oxygen. As the water temperature goes up, the ability to hold gases in solution goes down (chemistry 101). But the gases need to be released to the atmosphere before the water goes into t...

Re: Pre heating boiler water

Asteamhead,
I hadn’t thought about those problems. I guess that’s why the Worthington had two pumps, a cold-water and a hot-water pump. Maybe loofah sponges could be used to remove the oil, like is done with steam launches?

Re: Pre heating boiler water

What does the inside of the elesco look like ? Is it simply an open tank or actually a bunch of coil heat exchangers like the prototype etc on your PS4? In prototype practice, an Elesco feedwater heater was of the "closed" type, meaning the steam transfers heat through the walls of tubes containing...

Re: Trailer w. trains stolen in Texas Saturday

"Dairy Carcass Removal & Rendering." I like it! But perhaps it should be a magnetic/removable sign for your neighbor’s sensibilities ;-) When I am travelling with my trailer and (for example) parking overnight at a motel, I try to back the trailer solidly against a curb and then set the parking bra...

Re: Trailer w. trains stolen in Texas Saturday

One trick is to take the wheel(s) off on one side. Or, just take the lug nuts off on one side.
