I guarantee you one thing

when I start my own tank company, I will mandate that every hatch can be opened.

I can't stand these pseudo hatches.

Sorry but I needed to vent.

Michael!
I have opened all the hatches on vehicles in some builds. I usually take it on a vehicle by vehicle basis of late! Vent away, Sir. Knowledge to be found in all commo.

Painless

Lt Colonel. Maybe one day I'll do a full build.

Just venting about the Heng Long, Taigen, etc. ready to runs.

I enjoy opening moulded hatches as I do fitting working hinges to the front fenders on my PZ4s, I see it as another part of the hobby,
The brilliant part of our hobby is it caters for every level of ability whether it be a simple paint job or a complete historical rebuild BUT my bugbear is Taigen/Torro with all the tools and ancillaries moulded on the vehicle when Heng Long provide all of those detail parts on sprues leaving me the choice of aftermarket fittings or the status quo.

Col. Jarndice:

how do you hinge?

[jarndice]

Go to a Dolls House accessories site where you will find an array of Hinges, Square ones for PZ4 front fenders and long ones for front and rear Tiger 1 fenders,
Nuts and bolts are readily available on line and if you type nuts and bolts in the search box you will find their addresses.
I assume you have a Pin Vise, and a microsaw..
