100# for the locomotive deadweight. Batteries, motors, components. 300# for a typical heavy rider dressed in winter gear and a shove, So 400# sounds like a good operating load. 500# max load. Fun watching the empirical testing.
It is sprung for just over 900 pound loads, so a nominal 500 pounds would be just about right and there's still some headroom for people who are heavier than they admit.
HOLEY COW WHAT A LOAD! that is scary amount of material how much do you consume in a season? are the pellets more efficient then the “fire wood” that is split? friends have air tight burners for additional heating in their home. love your videos and the work that you teach on the maintenance on your tracks and rolling stock.
looks like something is almost out of gauge, either the track or the new chassis wheel set. almost falling off the track in several spots from the view underneath
I thought the same thing. Either your track is in need us some major realignment or your wheels appear to be out of gauge. Several times, it looked like the new wheels were about to fall off inside of the rail head.
He's mentioned before that the track is gauged for 7 1/2 but most of his equipment is 7 1/4. This is due to visiting equipment being 7 1/2 and he plans to have more visitors this year.
Nice , at least you have track showing, that has to be a bit of relief. Look like the new car is going to work fine. That is a lot of weight. Like you said before the new car offers a lot of options. Would small blocks on the frame help any with the rocking? Not that it needs anything done seem to work fine. I have one car that uses carriage bolts to keep the car from rocking, and it is adjustable. Great camera angle with the axle running. Wayne
Shocks would probably help but I didn't want to complicate the design that much. I very much wanted to keep it as simple as possible and I figured that was an acceptable amount of harmonic rock. The 105 does the same thing. I just wasn't quite prepared for the new chassis to rock and roll like it does so I took it very slowly. I didn't want to derail.
An interesting view point when the camera was pointed at the 'new' wheel set, going down the track. One could really see the smoothness, or potential problems, in/on the track. The '105' likes to derail quite a bit. Place a camera under the ends of the '105', pointing at the trucks, should/would show what is happening at the point of derailment and where, on the track, that point is. This would fine-tune the "reason" for the derailment(rail/wheels/both). Question - is the flange on the 'new' wheels deeper or shallower than what is on the '105' ?
Could you move the springs to the out side angle bar of the bogie frame? It seems like that would help with the car wanting to lean side to side, or wobble.
The center of gravity was a lot higher with the pellet load than it'll be with batteries, motor and a body on it. It'll still wobble a little, but compared to the 70, she's rock solid. In the design phase, the springs seemed to work the best where we put them. One of the things we were trying to solve by moving the springs where they are now was a little problem on the 70 where the trucks shudder when pulling a load. When we slotted out the mounting holes, in an attempt to make it track better, the trucks tried to flip themselves over. The challenge was to move the springs out to the front and back without complicating the design.
117.3 lbs with a spring rate of 221. Altogether, the chassis is sprung for 900 pound loads. You can get the springs from McMaster-Carr. www.mcmaster.com/springs/compression-springs-7/length~1-3-4/od~3-4/
All four wheeled boogies rock like that
Watching the wheels was a very interesting view. Great video
Very cool to watch the wheels tracking on the rail!
Great video especially looking down on the track...
The new chassis looks great, should do very well under it's own power.
Stay tuned...
Also another great video! Keep them coming.
Thanks!
The new car really works great!!! Thanks for sharing.

Interesting display of the experimental car. Eaglegards...

You should invite hobo shoestring up to your railroad. I think he would have an enjoyable time. He is a railroad hobbyist.
Good idea, but usually he hide himself for the ride, and at 1/8 scale...pretty hard to be invisible. 😇

The gauge does need attention in several areas. That and it's 7-1/4" gauge equipment on 7-1/2" gauge track.

I was thinking it needs shocks.

The 105 derails with severe twists in the track. Not much to be done about that besides fixing the track.
The hex head bolt with the rusty washer under it is loosely turning. Maybe a drop of locktite will solve that.

70's drive chains need some lubrication desperately.
Indeed, they do. She also needs new trucks.
the rear drive chain look a bit loose, it might jump off the sprocket.
Would stiffer springs or shocks help the rocking?
Shock absorbers, maybe but its center of gravity will be lower when it's fully assembled so I think it'll be less of an issue.
Im building a new locomotive as well for 7 1/2 inch gauge and was wondering where did you get those springs? how many pounds are they rated for?
117.3 lbs with a spring rate of 221.

Try to build a system in your Loko to recharge your Battery while you Drive Downhill some Kind of a Power recuperation system
It's already built into the motor controller. It's called regenerative braking.
@@MillBrookRailroad ah okay
use your dynamic brakes :-}
What if you took the two engine frames and made one 8 axl geep
I could, but then I wouldn't be able to get it in my car.
@@MillBrookRailroad then just fold it
Lol
@@MillBrookRailroad are you going to run both of them one at front and one at back or just retire the old one for the springy one
@@scr2392 I'll run them both. Sometimes one on each end, sometimes both engines together on one end.
it is scary the words I use as a chemist .
