Re: trucks for HOn3 cars with pin bolsters
- John S. is right. As he says, look in he MicroMark website for for Bulls Eye Drill Jig. MicroMark indicates that it is for repairing sagging couplers on Athearn cars. It certainly appears that is can be used on almost any car.
Coincidentally, there is an article in the May 2013 issue of NMRA Magazine about repairing couplers on Athern cars using this jig, which is manufactured by A-Line. In the same small package with the jig, is a tap for a 2-56 hole. A separately sold package contains just a no. 50 drill. Another separately sold package contains 50 short, black 2-56 x 1/8 screws. And another separately sold package contains 12 metal coupler covers for Athern cars.
The only difference between the contents of A-Line's single package that contains just the jig and the 2-56 tap is that the Micro Mark package has just the jig and 6 screws but no tap. Most modelers could scare up a no. 50 drill bit and a 2-56 tap.
With best regards, Hart
