I have a Lionel scale Hudson from 1990 that I’m upgrading to ERR TMCC. I did one of these before, but I want to keep it simple this time around.

Just upgrade to command, but keep the original motor, smoke unit, and sounds. I have the AC Commander that I’ll mount in the boiler as well as replace the handrail stanchions with TMCC plastic ones (also need to scrape away at them a bit so wires can solder to them). I have an older sound converter from ERR I’ll use to power and control the RailSounds 1.0.

The last thing I need is weights for over the drive wheels. The locomotive originally came with this large weight mounted over them. It weighs about 14 1/2 ounces. I would like to get another weight that is shorter but of about equal weight so there’s room for the AC Commander inside, but also ensure the locomotive still has decent pulling power.

If anyone can recommend some good weights, I’d love to hear suggestions!

Most conversions of this nature put the electronics in the tender (including antenna), then make use of a tether (not a hard thing to install), so your weight could stay where it is. I'm sure that you know all this, so I wonder why you are going this way.

Pretty much what D500 said. That’s a lot of work for such little gain.....pack everything in the tender, then either isolate the tender shell from the frame with tape and nylon screws, or come up through the coal pile with the antenna, and bury it it thin layer of “new” coal......fab up a tether, and roll............Pat

The Water Level Route.......You Can Sleep

To answer your original question, to get more weight in the same volume of space, you'll need to use a material with higher density than the zamac the factory weight is made of.

First- I would try it without the weight.  You might be surprised, it may be able to pull the desired load.  Since the 1990 Hudson DOESN'T have rubber tires (love!), a little wheelspin is prototypical.

Second- among common materials the most obvious choice is lead.  Lowe's and Home Depot used to sell lead chimney flashing.  It looks like a stovepipe hat.  You have to cut the stack away from the base.  Then you can unroll the stack and cut strips (laminations) to build up the shape of the weight you want.  It takes a lot of planning and cutting.  You can adhere the laminations together with rubber cement.  Another approach with lead, is to make a mold out of wood or plastic in the shape you want, and fill it with a mixture of buckshot and white glue.

A more exotic material is "Wood's metal" aka Cerrobend.  It's a lead alloy that melts in boiling water.  You can buy it from specialty suppliers online.  You'll still need some kind of mold to shape it.

I agree with the others who advised you to put the electronics in the tender.  Ditch the original sound and go with ERR sound, then you'll have plenty of room.  It's better to "float" the tender (insulate the shell from its frame with Kapton tape all around) and use the whole shell as your antenna.  Don't fool with the handrails or trying to bugger up the coal pile.  Been there, done that, and it doesn't work as well.  Hope this helps!

Creep, coast, and pull.  We're not talking about cold fusion here.

I had to add weight to my HHP-8, I took a "shot" and added it this way.

The bullets are 200gr .45ACP, and they had lousy accuracy, but the work great at weights.

some other posts have suggested stuff (including the above stuff,) like BBs glued in place, fishing weights, car tire weights, I've even used pennies. I didn't have access to GRJ's bullets! Hot melt and/or double sided foam tape also works.

I'd agree with moving the main board to the tender if you could.

Lastly, I have cut, shaped and moved around the original weights to gain room.

It's nice to hear that there's an O scale 3 rail loco out there without tires on it! Hey, I never knew.

Why go back to DCC when I have DCS!

I've chopped a lot of weights in brass locomotives to fit stuff, many times to get fan driven smoke in, I have to hack the weights.  For tender weights, lots of times I have to remove the stock block and do different weights to fit with the expanded electronics.
