Rob. Why not just go down the track of making laminating handles with inset bronze bushes to seat the saw bolts. That would seem to resolve all the concerns you have raised.

That could be interesting.
Thought I should say something I've been sitting on the saw line on this one

Mark at Bad Axe is already doing laminates. Bad Axe Tool Works - American Kid
I personally don't care for the high contrast 50's look of the majority of laminates. plan59 :: retro 1940s 1950s decor & furniture :: malarkey plywood, 1955 picture on VisualizeUs
I want good looking natural wood that is robust and stable.

Mesquite burls in in situ. If you look closely at the first photo you can see the mistletoe growing from the branches in the background.

Ok this is my take on the great saw bolt debate.
I made these earlier today ,they are ruff but in my defense I've been using my metal lathe for about 5 hours so far.
The photos are pretty self explainer try .
But the details are thread is M6,
Bolt head size is 13mm,
With a 45 degree bevel ,
Personally next time I think ,I will go with just flat head off about 3mm .
The bushing is 8mm ,
The bolt heads have also be drilled with 2 1.5mm holes placed 9mm.
Apart of the centre axis ,
These are designed to accommodate a pair of straight cir clip pliers .
Over all I'm happy with them ,
But they did stretch my skill
My reason for not going with the 45 bevel next time is that when ,tightening them up they pull down and also put to much sideways pressure in the counter sink.
Were as a flat will just pull together,
(Hope that all makes sence)
I may also think about making the bush just a fraction over size next time .
And freeze it in the freezer for a few hours before dropping it in to place letting it come back to room ,temperature and locking in place
Similar to old fashion vale guides on a cylinder head.
Now these are just my ramblings
So take them just has that

I really like your design. I agree with your thought on going for a flat face on the wood side. The 45 may split the stock in use and certainly will if overtightened. The large diameter bushings will carry most of the force if they fit the hole in the plate tightly. Punching that size hole in thicker saw plates will take a heavier punch though, what did you use?

I have no problem with the principle of the concept. I quite like the two holes for tightening them up and think they could look more finished than the split nut. I agree that the backs should be flat.
Two questions for you though. What is the off centre hole for? and why make these three part when they could be two part bolt and nut?…..Live a Quiet Life & Work with your Hands

Hi Rob
If u look closely at the pic with the handle you can see that yes it will split it.with a 45 deg bevel
Because it has!
live and learn
With regards to punching the saw plate holes at present I've just being using ordinary twist drill bits starting with a 2mm and working up to 8mm
But it's hard going and a big pain
So I'm up for any suggestions there I have thought about buying a metal hole punch
Or maybe making a tool steal cutter ?

Matt. I use a metal cutting fluid when drilling into saw plate steel. The friction generated between the drill tip & saw plate creates more heat build up than the surrounding air can cool. The cutting fluid acts as an additional coolant as well as a lubricant between the 2 surfaces. The metal cutting fluid I use is has the brand name ROCOL RTD. Reaming Tapping Drilling | RTD Liquid
2, 5, then the 8mm size should work fine with the cutting fluid. You may need to give the drill bits a resharpen if you have already burnt the tips from previous use.
