And according to this table

the setting allowance should be just over 9mm and so 15mm is definitely wrong IMO.

When shipbuilding I believe the rivets were thrown up to the guys setting them while still red hot. They then peened them while hot, the cooling process working to pull the two pieces together tighter.

Get your hot gauntlets out Rog! :eusa-think: :lol:

Wonder why you need a pein hammer? I'd have thought a flat faced hammer would work just as well.

More of a spreading action with a ball pein hammer and less likely to split. Plus you can shape it flush easier and the little dents look nicer :)

Burned the old wood out quite easily

Image

and removed the rivets. Interestingly I notice that the holes are on a slant. Not sure if this is by design (because of loading on the fork when in use) or just the way it is. Any ideas ?

Image

Marked out the handle on the ash and ripped off the excess. There was a lot of reaction wood inside the ash. Just hope the handle won't go all bendy on me. And was able to align the handle so I could cut out this split/shake

Image

Apologies for the poor focus. I really seem to struggle taking a decent photo with my phone.

Image

Started to plane the square into a circle and then realised that I would probably be better off drawing some reference lines down the length on all four sides.

Image

But I realise that it's going to be a long old haul converting the square cross-ection into a circle and with unsure results to boot. So then I came across this on YouTube which is rather good.

Hard to tell from the pictures but the misalignment of the holes would happen if the metal bent in use. Sharp radius 'inside' the bend moving the holes relative to the larger radius on the outside. in which case the handle to tines angle was different when it was first made.

Staggered holes caused by differing radii of the bend?

Neat idea with the BS - I've done it on a smaller scale with my router to make dowels.

So I tried the technique in that video.

First try - hard wood dowel
Image

FAIL !

Image

Second try - used a 6mm screw with its head cut off. That too was a FAIL...just snapped off.

Third try - 8mm bolt threaded into the end. That too was a FAIL...it just ripped the thread out.

No idea why they all failed. There was a very loose fit in the guide hole. So I abandoned that and resorted to good old fashioned planing using this guide to check progress.

Image
And that got pretty boring, I have to confess. So I decided to focus on getting the wooden shaft as far in to the metalwork as possible and then worry about the rest of the shaft later.

This is where we are starting from. The original shaft was very nicely tapered into the very end of the metalwork and so I have a long way to go.

Image

The ash remnants inside the metalwork proved excellent at showing the high points that needed removing.

Image
Image

Until finally, I think that this is pretty good.

Image

But now for the :eusa-doh: moment. I'll leave that for the next post.

I realise it's not the same as making your own but replacement handles are not that expensive
