| Subject: | AFV Club "Long Tom" Fix |  |
| Date: | May 29, 2008 |

Hi,
Yesterday, I posted a message about the problem I experienced trying to depict this gun in the travel configuration. The problem was that when the gun was fully assembled, with the limber attached to the trails, the two pair of the main carriage wheels closer to the limber were ~40 mils off the "ground". My concern was confirmed by one of our fellow modellers (thank you Bill), so yesterday I sat down to figure out how to fix this little annoying problem, and I found a very simple fix. So, here it is for those of you who are building, or are planning to build, this kit (and I assume that all of us who bought the recent release of the M4 HST will sooner or later want it to tow the awesome M59 gun).
My description of the fix uses revised Step 6 from the AFV Long Tom kit instructions as a reference for part numbers.
1. Glue A6 and A7 to A30 - do NOT glue A37 yet.
2. File the end of A37 that attaches to A6/A7 such that a wedge shaped gap is achieved on A37. When A37 is dry fitted to the A6/A7/A30 assembly, this gap should be ~20 mils at the top of the A37 end, and taper to 0 at the "bottom".
3. Glue so prepped A37 to A30; do NOT glue it to A6/A7 yet.
4. After the glue has set firmly, push on the bottom of A30 with A37 such as to close the wedge shaped gap (it is very easy because the bottom of A30 is moulded very thin, so do NOT scribe it) and glue A37 to A6/A7.
After the above is done, when you insert the carriage suspension (assembled per Step 8 of the instructions) between A4 and A5, the axle alignment will be such that all four pair of the main carriage wheels will touch the "ground" with the limber attached to the trails. Btw, this fix can be implemented even if the gun carriage is already fully assembled (like mine), you just have to be careful not to cut through A30 when separating A37 from A6/A7, and you have to have a thin file (finger nail file) and a piece of sandpaper on a fairly rigid backing (#220 wet/dry worked well for me). Cheers, bob |
