SBT is home

Took loco 2 and the brake car to White Creek for a few days of double heading with Robb's engine switching with Jeff.  Fun time, except intermittent locking up of the handheld about every 20 to 30 minutes.

I also took the SBT, which also has a radio system in it.  It ran well, until the batteries were drained.  I had not charged them before bringing it to Robb, and he did not charge while he had it, resulting in 19 volts at rest, 17 to 15 under load.  We used the MU set to drag the SBT back to the yard, and had a resting voltage of 20.5 volts.  As the charger was not hooked up properly I just let it be and Jeff and I ran with the other locos.

Now that it is home I will charge the SBT and ready it for the next event, on August 6th.

program

I used the DEscribe software to download the current map and then make a version with the forward and reversed swapped.   I also cleaned up the garage.

Running again

 Not Running
Running

So tonight I finished wiring up the loco for the second time.  It only took one emergency run to Lowes to buy some of those ring to wire connectors.  I bought a whole set of them for $17 because they did not have any small packs of the size I needed.

Then on the first run the motors made noise but nothing happened.  My suspect of motors fighting eachother was confirmed by removing a chain.  After reversing the lead I had a bear of a time getting that chain back together.  I ended up losing the motor a little so the chain has more slop that I really wanted.  To get that out would mean disconnecting the batteries again.  As the chain is tighter than it was the last few times it was run I will leave it until I install the final bases.

Mount the Sabertooth

 Tonight rather than take pictures of guys doing this.


I mounted the sabertooth on the electrical panel.  Soldered longer leads onto the MU tether selector switch and mounted that also.    To do that I had to sand and clean up my mounting board of excess gorilla glue and soften the corners.

I bolted down the battery locator brackets on both sides and test fit the shell.

Wood plate

 After pondering using 1/4 plywood or solid wood or 1/2 inch plywood.  I used the 1/2" ply as it is what I had on hand.
 I cut it to size and drilled clearance holes for the bolts and bolt heads.  On the next one I may not drill all the way through for the bolt heads.
In other news I took apart the all of the drive train above the deck of the loco, remove a link from one of the motor chains and turned one of the motors over to have the lead reach to the new sabertooth mounting location.  I decided not to change the length of the lower chains as with no weight on the loco the chains only light slack.

Loco 2 electronics mounting boards

This morning I mowed my section of CVAST trails.  About 2.5 miles out and back, add in the three area that take about seven passes to clear the tall grass and I am guessing about 3 miles plus of walking in 2.5 hours.

Then I took a 3 hour nap.

 So I took some of my raw oak and cut out six 2x2.

 Then I used the bandsaw to add a chamfer to two sides.
 Then I sanded the sides I just cut.
 Then I trimmed the other five.  This time I got smart, I made a jig and used the table saw.
 Then I sanded all the surfaces, rounding the chamfer to the flat below.  Now you can see how they are set up.  Corner posts that stay on the frame, with the ability to guide the walls and roof into place.
I made six of them to have a test set.  The panel is to mount all the electronics.  Drive and brake at one end, the other for sound system.

Work stand

Well I was was found redundant at work and am now currently seeking new opportunities.  I sulked around for a bit not wanting to do the hobby.  But today I was in a sour mood due to having to seek.  So I decided to do some productive procrastination and put together the work stand.

 Lowes had 9 inch carriage bolts.  The ten inch hex head bolts did not have threads for a long enough length to work.  I was not in the mood to custom order something off the net to wait.  So I used an oversize lock washer to offset the square part of the head.
 I drilled the rails in the basement on the drill press.  One end supported by the toolbox the other on the drill press.  Then when I did the second one I C-clamped them together so the holes would line up.
 Then I took all the parts out to the garage.  First top was put together.
 Then the legs C-clamped in place, the legs drilled, and bolted.
 Then I mounted the casters.  I had drilled the caster holes back when I cut the parts for the legs, only a little bit of weld slag in one of the holes to drill out.
Here it is.  I plan to make some locking blocks to chock the wheel so rolling stock does not roll.  I also plan to make a bridge that hooks onto the end and my lift table.  The length is 10'6" all the rest of the 20 foot sticks went into the leg system, and because I had messed up on cutting I had to use some 3/16" thick angle on the legs also.  If I get or start building a large loco I will add diagonals from leg to the outside for bracing.
