Yes the Sherman swing arms had a cast-in assymetric bumpstop underneath to limit the travel. I have photos of the upturned suspension units belonging to the "cut and shut" Grizzly featured in the original Tank Overhaul series. If you want to post them for me!
My advice is to run the tracks tight but if you have very pebbly terrain to replace the steel M3 bolt that locks the idler adjustment, with one made of brass. It should fail before the track snaps if the worst happens. Fiddly to drill out and replace but cheap at least.
Best to avoid gravel, sadly the real world does not scale down with our models and nor do the laws of physics.
cheers, Fabrice

Fabrice,
I would like to see the pix you have of the swing arm stop. If you want to send them to me via e-mail I will gladly post them here on the forum. bobmorey2@yahoo.com.
Not a bad idea on the brass screw option. Thanks for the suggestion.
Kind regards,
Bob

Fabrice has graciously supplied some excellent photos showing how the "real" Sherman type tanks had stops cast into the bottoms of the suspension arms. This stop prevented the suspension arm from over travelling and folding back on itself.
Now to figure out how to do this in 1/6 scale!
Thanks again Fabrice for the excellent high res pix.
Bob

Bob,
Ingenious way to stop the problem. That is definately an upgrade worth investing in, I have no doubt you will work in out.

Here are some videos of my Sherman running. The tank isn't quite finished (but I couldn't wait) and the videos are not that exciting. They are fun to create and edit to see what effects you can do with today's technology.

Bob,
Good videos. I noticed that the track starts to tuck under behind the sprocket, so I think it would be good to tighten the track a little. The barrel lock looks reay good, it will be a superb model when its finished.

Bob,
Thanks for cropping and annotating my photos so neatly!
As regards your model track tension, I would say that the tracks need to be run in for a good couple of hours to scrape off any high points, surplus paint etc before doing further tightening. My first few runs displayed quite a lot of sprocket bind but this disappeared after a run in period. Suggest loads of dry type lubricant in your dusty garden environment!
Look forward to seeing lots of Allied models on Saturday.
Cheers, Fabrice

Hi all,
Its been a while since I posted any photos so thought I would add a few to liven up the Sherman forum a bit. Some photos of the Alum alloy deck I made for my Sherman and the latest front glassis armor bits. Enjoy. -Bob

Great to see a Sherman on the forum
I missed seeing your videos - love the low down shots.
I'm not sure "No Good" is a fair sound track though, even if it is by the mighty VH.
Adrian.

Hi Simon,
Likewise I'm enjoying your progress on the Panther. Thanks for the comment!
Thanks Matt, how's the Tiger coming? Adrian glad you found the vid's entertaining. I need to make some new ones.
I took a second look at the first version fenders and realized they were not quite right. After looking at photos of Dales great Sherman build (THX Dale!) I decided to remake the fenders.
This version look a bit better, happy - Bob

Robert,
Your Sherman is looking really good. You've mde a nice job of the new hull top and everything fits really well. There is a ton of detail that can be added to these kits and I think they run really well when adjusted properly and run in a bit. They are also lighter than the Tiger and easier to man handle if necessary.
