Excellent... TWO day delivery from Fox Valley!!!

My first look: Gold Coast Code95 vs Fox Valley Code70 wheel sets -
Code95-vs-Code70.jpg
Code 95 vs Code 70 wheel sets in GCR trucks
NOTE: These wheel sets are -NOT- a total drop in... but can quickly be made to run.
For Quick Running:
The Fox Valley axle is .005 narrower than the GCR (0.720 vs 0.725). To compensate, the bolster is easily narrowed .005 by taking the truck apart (the sideframes have a pin which pulls out of the bolster with some coaxing...) and giving the bolster ends several nice perpendicular swipes with a fine file. (The one you -never- use for metal...)
This keeps the wheel sets from falling out... and is shown in the photo above. Be careful and get the tops of BOTH sideframes installed right side (closed part of bolster) up. Many will want to stop here as a "good enough" installation.

For the best look:
A further consideration is that the Code 70 wheel sets are -each .025 narrower that the Code 95 ones... (amazing how that works!) This is why you can see more axle outside the Code70 tire in the photo!. Solution: We will need to deepen the conical sideframe journals. Luckily... Reboxx sells exactly the right tool for this: http://www.reboxx.com/Tools.htm. This will also dictate further narrowing of the bolster. I will post a photo of the mod this weekend.

Just bought the last 100-pack from FVM. Hope this means the wheels are selling well. He does have more than 10 single packs left, though.

Glad I didn't hesitate.

Gold Coast Railway Co. question. Does the company still exist? I did a Google on it and it showed no web site anymore. Reason I ask is I'm going to attempt to see if I can cast the truck side frames in a resin. If it works out OK I'm going to try and cast 25 sets of trucks for the 100 axles I got. This won't happen for a while. Probably this fall or later. Right now I'm working on an On30 critter for a client and it needs to get done.

Have you tried to search this board? :lol: :lol:
GoldCoast has been sold to Lok-n-roll. http://www.lok-n-roll.de/
Anyway, if you make new trucks in resin, please try to make a different type than the existing GoldCoast trucks. TT scale community needs variety, not copies. Would you be happy if you spent a lot of time and money on the mold for injection molding and then people would just made resin copies of that? It may be protected by copyright (but the company is probably too small to sue you). My concern would be rather about damaging the existing manufacturer by making resin copies of their product. We have to support those few NA-TT manufacturers, not the opposite!
It would be a different story if you selected Kemtron trucks for the resin copies. That would not harm anyone and they are really nice, made by lost-wax casting technique.
Resin trucks can work very good if they get brass bearings. I use resin trucks for my passenger cars.

The tool was designed to span a HO truck and do two sides at once... not needed for us.
The 60-degree conical tool end is what I'm using... -ONE- sideframe at a time.

I'm wondering if this is even necessary? GCR (in the US) used to sell the trucks unassembled.

GCR sprue - unassembled trucks
(Note that there is still some casting flash...)

So... could Lok-n-Roll (EU) offer the same?

Played around with the wheels today. They look good and work well. I tried them on both Tillig and Kuhn track and switches. No problems!
