Hello Gingerale

Welcome to the forum, it's always a good idea to put your ideas up for others to view.

I don't know which pictures you have been looking at but if you look at any reference book describing the gun carriages you will find that they do taper in the way shown. The trucks (wheels) are fixed onto wooden axle stubs which are parallel so the wheels run true.

I have uploaded two pictures from the gun deck of HMS Trincomalee - the world's second oldest floating warship, when she was being restored at Hartlepool. It shows the fore axle tree as being narrower than the rear axle tree!





Hope that helps and you will keep the gun carriage with the wide end towards the rear.

Mike T

Hello Mike,

Thank you for your reply, yes I see the difference between the two axles in your photos.

Another thing what I noticed after my yesterdays post that the position of the rear wheel is too high, it can't reach the floor.
I think we need to sand off about 0,5mm from the bottom of the side parts.



Happy building for everyone.

sorry I havent responded Holidays do get in the way of things!!

you are correct about the rear truck although I have not had the problem to your severity. i would indeed sand back the block untill you have at least 1mm clearaance.

Glad you have been inspired to add some detailBigGrin BigGrin

Hi everyone,

because I find to hold the wheels a bit tricky during the upgrade, I've made a very simple holding tool from scrap wood. See the pictures.
It has two sides, one for the bigger wheel, one for the smaller wheel, they look the same.
The two lines represents the 60 degrees between the bolts.

Note:
Make sure that the wheel sits tight in the tool. If it's floppy the filing of the slot should be very difficult.






I hope you will find it useful.
