Lou, I was looking for how you were going to keep the debris from being re-distributed on the track. Didn't see how you would 'empty the dirt bag'.

If you look at my picture again, you will see that the area in the red square at the front of the Boxcab holds all the dirt and dust. Nothing gets into the rear yellow colored section past the filter. These do not use vacuum bags like your home Hoover. The dirt collects in the boxcab, when you empty it, you take off the shell, and dump it out.

Read the same thing I posted for David. And your question is no bag used. It's not your home Hoover. See video link. https://youtu.be/cKMExevHZjc The chute similar to my drawing below pulls up the dirt/dust and pulls it into the Boxcab, and it won't fall back out. To empty, you pull off the Boxcab shell and dump it out. Replace the shell and off you go again.Originally posted by BurleyJim View Post

Louis,
Although I wouldn't attempt this, you are doing an amazing job, just like we all know you would.
Actually the concept is great and when you finish, you can admire all of your efforts, and say "I built that !"

This is great engineering Louis'.. and an excellent creation... I could sure use one of these in O Scale.....
Nice job as usual...

Thank you for the diagram. I found it helpful to understanding the concept, particular using the curved "nozzle" to keep the dirt where it belongs, and not falling back out.
Will you be making the pickup nozzle adjustable to any degree, perhaps temporary, to find for the best height?Home of the HOn3 North Coast Railroad, along the shores of Lake Ontario.Comment

Rich, thank you for your comments, and following along with this build.

Ted you could do it even easier being "O" gauge. And thanks for your comments.

Hi David, thanks for your thoughts and comments here. I'll be making the height of the nozzle 1/4" off the track tops. All the commercial ones are set around that height.Originally posted by David_J_Buchholz View Post

Yesterday evening I took the piece of “whatever it is” and cut the filter holder that I needed from it. See picture below.
Then fitted the shaped cut piece into the slots already on the MDC chassis where the original MDC Flywheel Bracket went. Now, I’ll have a strong enough screen to hold a vacuum cleaner piece of filter material to hold back the dust and debris entering the Boxcab chamber.
Now, what I have to do is make-up some sort of vacuum nozzle to fit into the cut center portion of the MDC chassis, facing down to the track area for dust and debris pick-up. See last picture posted.

Louis that is a great concept you have going there. Being that it's not going to be very long
would a small piece of neoprene hose work. That way you could easily trim it back until you
achieved the proper length that you want. Keep up the great work.Owner, General Manager, and all around "chief cook and bottle washer" of the Caz Coal-and-Wood RailroadComment

Thank you for your comments Larry.Originally posted by Larryc View Post
You suggested using a piece of neoprene hose. And, if you can believe it, there is a computer vacuum cleaner that uses the same thing for their nozzle.
It is a good idea, however, I'd rather go with a solid nozzle style, like all the Model Railroad Commercial vacuum cars have. They are all set at 1/4" off track top.
David (David_J_Buchholz) suggested the pickup nozzle be adjustable also. And, I do like that idea very much, but I think I'd be adding to my headache of just making a permanent height style.
Then again, I guess if I made a unit that slides into each other, I could push it up, or pull it down to adjust.

Again, with a convenient original MDC part to make things easier for me, the Cover Plate that mounts to the underframe with four screws, where the original Gear Housing went for Non-powered Track Cleaners, I can use this for mounting my vacuum nozzle to the underframe. This part also holds the shell down onto the frame. Following along with the pictures below, I have the MDC gear housing cover plate in place, where it would have been mounted. Taking this cover plate and cutting an opening into it, I’ll be able to use this part to mount a fabricated vacuum nozzle to the vacuum track cleaner Boxcab. Now to fabricate a nozzle of some kind.
