25 Pounder info needed.

[Private_collector]

Found a photo showing the canvas cover for the slide rule. I think I will make the brackets and a cover like in the photo, and give the appearance of rule being in place.

Do I understand correctly that the instrument was 23" long x 2" width? I have a very nice piece of 6mm thick aluminium plate that would fill out a canvas cover quite nicely. I can get the bracket dimensions and footman loop placements from my local gun, but are there any other specs or info I need to get this right?

One more question. I have seen many variations of finish on the 'head' of the range sticks, and even seen some partially painted red, so my question is.....how are they meant to be painted?

P.S: I take it that the chap in background of the 25pr photo is probably NOT interested in military history!

Aiming post heads should be Black and White.

Tony,

Looking good ..... some nice touches going onto your artillery piece.

The No.20 Fuze Indicator (ie the slide rule) mounts are 690mm apart, and the top edge of the brackets are 18mm from the top edge of the shield. The right hand bracket is positioned 40mm inwards from the right hand edge of the shield.

The two footman loops are 125mm from the top edge of the shield, and the right hand one is 230mm inboard from the right hand edge of the shield. The Loops are standard 55mm centre to centre, 15mm deep loops.

The base of the bracket measures 80mm x 43mm, and the depth of the part that holds the Indicator is 20mm deep, 30mm wide. The brackets are held on by 3 rivets, round head type, with the round heads to the outside (front) of the shield.

Measurements are from your local gun at Tiaro.

I have a good drawing of the No.20 F/Indicator in a Canadian parts book if you want to try and do any replicating, or have it for reference in case something like it comes up for sale.

How's the heat and humidity???? We are now basking in 0 degrees again .... mmmm lovely!

Best regards

Mike

Mike,

Thanks for those measurements. You save me driving to Tiaro again.
A piece of aluminium cut to size will do me for now. Good of you to offer though.

How bout we combine both temps and divide by two. I'm sure you can live with 15 degrees, and my 15 would suit me fine. I could get back to the engine building without dripping sweat down it's throat. If there is anything you discover you still need measured from Tiaro, just let me know. It is rather closer to me now, than it is to you!

I think I'll start referring to my fake as a 'quarter-pounder'. I'm sure you folks in USA will get the hidden meaning.

Well, a couple of things to tell.

The ranging sticks are finished. The white stuff you see in the retaining brackets is cotton material to avoid scratching the sticks. Have since obtained some thin green felt to use permanently....after painting, of course.

I have located and purchased a ground anchor cover......in the Netherlands! Purchase price was very reasonable. Shipping cost was horrendous. You only live once. I originally intended not to purchase, but what the hell, eh!

And, the zero plate and block have arrived from Rob N. I'm cleaning the plate right now. The wooden block is a work in progress too.

This weekend I want to make the track for the sight door to slide in.
Made templates for that, one night through the week.

Bought steel plate to make the brackets for the two wooden boxes.
Templates for those were made 2 weeks ago.

Rob N, here's your zero block. I tidied it up a little. It will be attached next Sunday.

Because of a transient episode of laziness, I only spent a couple of hours in the workshop today. It took me nearly all that time to fashion the following piece, being one half of the sight door sliding track. I think it's the harder of the two parts to make, so other one shouldn't be so painfully time consuming. Two hours of hand filing is my limit, I'm afraid. Never again.

It isn't really wider on the right hand side. It's a trick of the angle of photography.

A couple more questions folks.
Sorry for the poor quality of the following photo.

What is the item to left of the rope bundle??
If a shovel, it's not going to be very useful!

I occasionally come across photos showing box carrying brackets in locations forward of the shield. Why some do and aome don't? Is it worth recreating this on mine?

And does anyone recognise the type of box behind the soldier.


WOW, just WOW!

Impressive photo, but WHY does the flash curve upwards of the barrel angle?!?!?!
