while constructing this kit i noticed the road wheels have ridges on them. is this something to do with gripping the track or an error in design? the ridges radiate out from the road wheel not around them on what would be the rubber section.

no takers on this one yet! if it helps its the Trumpeteer kit with the mine plow

Bas Hermsen built this model and put the photos on Myssing Lynx...

Hope this helps!

The tyres on this Iraqi tank from Prime Portal have a sectional appearance, though with grooves and not ridges

Tyres

You mean these?


I have Tamiya's kit in my stash so I dug it out for comparison. It's wheels had ridges on the sides, but not on the contact surfaces. I tried tanxheaven and I found this pic:


Looks like the ridges on the trumpeter wheels are an error. Also, they should be recessed, not raised.

That's one fine model, but there's a small error regarding the paint job. That sand color should really be light green. That color is almost right for representing very faded light green (it should be a touch greener), but then the black and dark green should be faded as well.

When I first saw those pics, I thought that sand color was completely wrong. But then in the army I saw some old collapsible brigde devices that had very faded paint jobs. The light green had faded to almost dark yellow!

(I also found out that there's no absolutely right colors for painting the older M/62 camouflage suit. Those colors do fade! One time one of my roommate got a brand-new and still stiff suit from the laundry, while I got a very well-used suit that was made in 1971! That newer one looked like it was made for forest environment, while mine looked liked it belonged to desert warfare! :-))

thanks guys looks like the scalpal has some scraping to do.

The ridges are supposed to be there. It comes from vulcanizing the rubber to the roadwheel. I have seen 30+ year old M113 roadwheels that still have their vulcanizing ridges.

Trumpeters are somewhat overdone, but correctly portrayed as ridges. Tamiya screwed up and have them as recessed lines...not correct. However, as you see, once in use, the ridges that are in contact with the track wear off quickly.

thanks for the quick save, that reduces the amount of scrapping i need to do. now is there anyone out there who can reduce my workload further?
