Progress on rebuilding the tender.

I've plugged the holes in the deck (f'it, it's not getting tool boxes) and have build up the missing pieces with some strip. Here they're drying out before I shape them. The one piece is still way long so I can wrap it around.

Ed, you might want to consider stripping the paint before you get too much farther.  Whatever you use to strip might attack your glue joints.

Yep, you're absolutely right about that!

What are the cool kids using to strip paint these days?

My first thought is just to try some 91% alcohol and see if that gets me anywhere. However, this tender being the age it is, I feel like I might need something stronger (since it wouldn't surprise me if that's something nuts like lead based paint left over from painting panzers or something).

91% won't do it.  I've found Testor's Brush Cleaner can sometimes get at older, thicker paint...just be sure not to let it sit too long.  I've never melted plastic with it, but then again, I haven't wanted to.

You won't know if you don't try it.

Over the years, I've seen quite a few projects where people didn't strip paint first and just painted over everything. I'm stunned that this works out for those people, because I've ALWAYS had problems with coverage after.

Coverage should be fine, but you might see an outline of the lettering in the new paint. Try the 91% and rub the crap out of it with a q-tip.

I've used silicone putty to make mini-molds to repair a broken part. In this case, you could use it to make a mold of a similar section of the "flange", cast a duplicate, then trim-to-fit that part to replace the damaged/broken section. The part would be guaranteed to match, rivets and all. All you have to do is hide the joint. That might be an easier way to replace the missing section and require a lot less "reproduction" on your part.


Here's the putty I've used - available at any craft store (got mine at Michael's)

That's what I'm doing now. It's been soaking for about 5 hours.

I do the same, except I use a pencil eraser on the lettering.

91% Alcohol + QTips = Worked like a charm.



I gave it a soak for about 5 hours yesterday and the green came right off. I left it over night and then could scrub the gold lettering off.

Thanks guys!

Ed, if you're unhappy with the mods/repairs you've done, I've got two of the little beasties you can have. And, they're black--easier to strip and paint.

Hot damn.

I will remember that. I've been very scared because I'm working without a net. If I blow this one up, I'll DEFINITELY be reaching out.

Ed, as long as you are on Railwire, someone will always be looking for a net for you.   :D
