Does anyone know what the tape size is for the two screws that hold the Exhibition flange on?? 4-36 sound right??


Yep, I busted one off...

I measure 4-40 on mine. (4-36 is an oddball!) Of course you already know that this is no "standard" machine screw; the shaft is ~13/32" long, and is stepped: the threaded end is ~3/16", the rest of the shaft (the shoulder, I guess you'd call it) is ~¼" and it's not threaded. HTH.

Thanks Henry,,, I have a few extra screws but I'll have to get a tap and drill the other piece out. Should be fun.. LOL

4-40 sounds good to me..

The flange screws are 4-40. fortunately, the taps and drill are fairly common. Here's another tidbit: The little screws and nuts are 1-72. Victor Exhibition needle bars use 0-80, and No. 2, No.4 and Orthophonic use 1-72. This is good to know in case these nuts and screws get lost.

Thanks, Harvey. This is essential information to have handy. All those small sizes are commonly in use by model railroaders; the proverbial "well-stocked" hobby shop probably carries the taps and drills. I purchased a set of Morris taps and holder many years ago: 00-90, 0-80, 1-72, 2-56. The hobby shop may also carry the screws, nuts, and washers in those sizes.

Thanks Harvey

Time to write this stuff down an tape it to the inside of a cabinet..

I'm a model railroader, too. That's how I learned about these miniature screw and nut sizes. It pays to get a miniature tap and die set. These tools are worth thier weight in gold. I really do miss these hobby shops. I have to buy these items online.
