Thread: I have recovered some sanity. A large square this time.

G'day Schtoo!

Great job - the square looks just lovely.

Are you planning your range of tools for later manufacture aka LN & LV, etc?

Excellent work Schtoo.

Now that Schtoo, is worthy of comendation and all manner of praise on the fine square you have produced....look out all you fine tool manufactureres and take heed of this guy in your presence.

Cheers stand by for orders.

Schtoo, good one mate, thanks for sharing it with us

Regards Mike

Beautiful looking square!!

Can you show the adjustment mechanism?

Ditto...Very nice.

It's a chunk of bloodwood with plain old brass everywhere else, save the steel adjusting screws that are well hidden.

A great tool, but like the major says show us your adjustment mechanism..... please?

Great stuff Schtoo.
Have you shown the adjustment mechanism in another post? Two rods that run from the base and attach to the blade? Not sure if that was you.

Lovely piece Schtoo!

cheers

Really very nice but no, I don't think that I can do it.

do you ever rest? Good job!

The adjustment?

Uhh, no!

Actually, I decided to move away from the 3 pins ala Mr. Clenton. I just wonder that if something this size and weight (not weighed it yet, but it's getting right up there) were to be dropped, there's a really good chance it would tear the wood apart. As it is, it's possible to top pin might blow out, but that's recoverable. To do both ends would mean I'd lose 50mm, and makes the square effectively useless. What I did at the bottom end is easy enough to just repair, as it would only be sheared out, not blowing out the whole end.

So, I threaded up some brass rod, 8mm outside, 5mm inside. Drilled and tapped the base to take the 8mm, drilled right through @ 4.5mm from either end. Cut the slot for the blade, cut some more 4mm brass rod for pushrods, stuck in some 5mm grub screws and there's the adjustment.

If I made one for someone else (hint hint!) I'd do it very similar, but also include a cavity under the bottom plate to hold the allen key for the grub screws.

I put the bottom plate on because these things don't need tweaking often, and I thought it better to leave the holes covered up. Mybe looks a little nicer too, even if a little blocky.

All the flat brass is 2mm thick plate, but bar would be much better. Darn guillotine stuff needs too much flattening out.


Making more tools, I think that's what I would like to do in the future. For some reason, I prefer making the tools than making the stuff with them. Always much happier punching out a tool, and every subsequent one just adds to the joy as I clear up problems and make it easier.


MkIV will be something different though. I have doubts about the wood wiggling with the seasons, so the next one will be a bronze casting with wooden scales. Same adjustment system, but no added on brass. Just the base and the blade. Unless of course I use a nice piece of stainless plate and another piece of ground SS bar I have kicking around here. No reason why I can't have an engineers square the same size, is there?

Just need about a heap of copper to start with.

Nothing looks better than brass and wood together! Very nice. Didn't follow the adjustment bit though - I'm a diagrams bloke I think!

This explains the basics of how the adjustment works.

I have just changed it to suit me.


And the truly scary part? To get a smaller 10" square would cost over $250. :eek: :eek: :eek: :eek: :eek:


I really am in the wrong business.
