Doug,
I am sure you are fully aware of some of the degenerate types that frequent these back lots of the forum.
Myself proudly wearing such badge of honour.
But due to you being my guest this fine Saturday for which I am very much looking forward to your fine company.
I will not lower my self to mention anything to do about your slot.
But of course on Saturday, will much appreciate a in depth discussion on said slot.
Cheers Matt.

Looks like I have full functionality of the forum back at last.I got sick of sitting around doing nothing - so I took up meditation.

I cut off a small piece of sawplate and drilled a hole through it ok. I took a picture but I still can't post it

Actually, there's a saw-nut in the hole. I used one of my Cobalt bits and a drop of cutting oil.I was going to try to draw back the temper a bit to make it softer but I thought I would try it "as is" and there was no problem.Earlier I drew back the temper on half of the piece I cut off the corner of the big Disston I am rehandling and found that I could drill through that. Before I got too excited, I realized that Mr Disston may have already tempered that part of the sawplate before drilling the holes for the old handle. I found that I could also drill through the end I had not tempered, so still not sure I achieved anything by heating that part up to 400 degrees C except that I did not damage it in any way by doing so. I wish they would fix the forum so I could post pictures again.

This is how Henry's boys did it:
https://www.criticalpast.com/video/6...ure-cast-steel
It's a very short 57 sec video (hardly worth breaking out the beer)and not very clear. Actually I am not sure whether they are punching the plate using the handle with holes already drilled as the pattern or whether the "stems" are drills. Unfortunately the clarity is so poor I can't really see, but I am leaning towards the plate being punched. I think this is the way the holes were made as there is usually as distinct burr on the reverse side of the plate that is conducive with punching as opposed to a slight burr resulting from drilling.
The first few seconds before the punching/drilling operation demonstrate how wheat carving was achieved. Early models (before 1890s?) were carved by hand, but Disston were quite progressive in utilising machines to speed up production.

You are right and the Disston empire was quite secretive. There are still a couple of aspects in the blade process that have not been revealed. Only Houdini had more secrets in fact. The other aspect is that the video is for sale and the inference is that the copy you buy can be HD or SD and is higher quality (where have I seen that sort of marketing before ). $150 to $170 is a bit steep I would have thought and I think that is large American dollars, not dainty Aussie dollars.
Anyhow, if you care to keep looking there are four other Disston clips. I re-read the information on the clip I posted and I got it entirely wrong. There are two sets of drill clusters, which also incorporate the counter bore for the head (and medallion) of the saw screw. The employee drills one side, flips the handle, moves across to the other cluster and drills the "flip' side. He completely drills two handles in twenty seconds!
How long does it take us?

How long it takes me is immaterial (there's that matter again). I am doing it for fun and enlightenment not for profit.
Here's a piece of 1095 with a hole drilled through it with a cobalt drill - The fact that I can post it means I have the power to post pictures again and smilies.

YOUR ATTENTION PLEASE, your attention.
Hi all, I will be there. Conveniently I am on a camp in Ballarat till Friday, so we’ve booked for another night. Me and mum will come, though I am not sure whether or not she’ll stay the whole day.
If she doesn’t stay I’ll need a drop off at the station
Also the stuff from Blackburn arrived yesterday, but I don’t have any actual tools with me. Can I borrow some of yours on the day?
See you then.
