You can get red oil from Constantia furniture in pt Lincoln

Yes. I have never used the Constantia red oil, but know another knife maker who raves about it.

Reasonably productive weekend.
Used the pencil grinder to grind the crossbolts down to the stock surface. Then polished them down with 400 grit wet & dry.

Ironbark forend tip is on.
Also fitted a barrel band sling swivel. I am going to have a traditional lace up sling.

The stock has had the grain raised and then sanded back with 600grit paper.
I made the barrel band out of some 1020 19mm steel plate. Used the rotary table on the mill after drilling a 19mm hole in the plate. The wall of the barrel band is 0.8mm thick. Polished it up with the pencil grinder.

Still waiting anxiously to see how that safety kit works out.

So am I, but I want to get it shootable before I go to the Chapman safety.
Once I get the stock sealed, barrel hardware on and rust blued, then it will be the 2 stage safety.
I am 80% confirdent I will be able to adapt the K98 firing pin, cocking piece and shroud to fit the Siamese Mauser. I will need to move the cocking piece forward on the firing pin and then I need to extend the actual tip forward which will involve tempering drilling and inserting some 2.2mm drill rod.

I was trying to be a bit obscure with my name but give a hint of location.

I went looking for a genuine Siamese Mauser extractor. I found one, it cost me AU$200 delivered,but it came with other bits.

This not a virgin action. It has been converted for 45/70 at some stage. A new bolt handle welded on (a bit rough), the bolt face opened up and the right hand feed rail opened up to help feed for the larger rim. It feeds 348Win cases perfectly.

The case above is a 348W that did not quite fire form fully for the 416/348W AI. Not enough pressure generated during forming. It only formed where the brass was annealed.
The rear scope mount is not the prettiest work I have seen and it is alloy - it will need some extra work and hopefully a change to a Leupold base.

I bought the action sight unseen. Before it arrived I was thinking 338WSM, but as the feed rails and bolt face has been openned more than standard that is now not an option. But I can use a 338WSM reamer (which I can rent) and headspace the chamber. While it is in the lathe, cut a grove to accept a rimmed case. So it would end up being a 338/348Win Improved. It would not be an Ackley Improved as the shoulder angle would be 35deg not 40deg.
Or I could go the other way and just do a 450 Alaskan.

The Auctioneer's Promise stock finish compound should be delivered this week, so focus will be back on the 416WSM.

Have you disassembled the bolt? Hopefully the dolt who welded on the bolt handled didn't get it too hot and warp the bolt. Not a bad looking handle if cleaned up, just not attached straight. You could probably true it up with a bit of grinding and polishing. I was faced with same problem when I bought my 98 Mauser action sight unseen from an auction.

2 coats of Auctioneer's "Red Oil" is dark enough for me.

A couple of days to dry thoroughly and then I start on the many coats of finishing oil.
