Doug has explained better than I could have.

There are diagrams online but I could not find them quickly. I have also seen a cutaway bevel gauge that shows the mechanism.

I'll have a look for a diagram or picture later when I have a bit of time.

My Wife bought me this one for my birthday, must have been back in 2009 .
Chris Vesper makes some of the best tools available in the world, and his sliding bevel is no exception.
As you can tell its a user, so the signature series may have been a bit extravagant, but she always buys the best.

He also made this little double square, a very handy bit of gear.
Looking at the marks on both, I really should look after my tools a bit better .

I drew a better side view of my plane, so I could make a template to mark the sides on the brass sheet.
Still need to refine the shape of the handle.

I wanted to build this plane entirely from stuff I had stored in my sheds, I have broken that rule twice now, first the brass sheet, now a new scriber.
This one is a $12 Sidchrome job, its not in the same class as the Starret one I cant locate , but it will do the job at hand.
I dont have any marking fluid, I found a recipe online to make some, but I dont have any shellac left. So I tried some spraycan survey paint.

I dont have a jewellers saw, as recommended by IanW, so I used my jigsaw to rough them out.
It wasnt a good experience for me or my jigsaw.
The only metal blade I had left was already blunt, and it was getting hot and brazing the brass filings onto the teeth, I had to stop every 10mm and use my new scriber for a toothpick .

I got them roughly cut out, just have to work out how I am going to finish them off.
Maybe a drill, holesaw, and files.

Looking good Brad,
I had the same experience with using the same jigsaw(I think) trying to cut my brass sides out.
No matter what I did it was just &@@&,

Maybe there’s a special tip?.

But I find filling the brass almost Zen like therapy, not sure if that is a sickness tho lol.

Cheers Matt.

I'll give you zen Matt!

I was reading about some German post war machinist apprentices , one of there first lessons were to file a cast aluminium cube to exactly 20.00mm square I think!

Each one they stuff up, they must carry in there overall pockets till they get one right.

Apparently Learning how to file and when too breathe is the trick !!.

Cheers Matt.

Get yourself one of these:

B002 - BS-4A Metal Cutting Band Saw - Swivel Vice | Hare & Forbes Machineryhouse

Just the thing for brass and annealed carbon steels. It can be used with an auxiliary table like a woodworking bandsaw too for cuttin gout profiles like what you were doing.

They sort of still do that. I did my engineering degree in Germany. Only moved here 10 years ago. During the degree we also had to do an internship for basic skills. I did it with other mechanic apprentices. We had to do similar tasks and the supervisors were very strict.

The apprenticeship takes 3 years whereas for us engineers we only had to do 13 weeks. Not enough to really learn the skill but enough to generate the respect for those who can and to appreciate the abilities of the ones who have to build what comes out of our crazy minds.

I would like to put forward a formal protest,
Cklett is a formal trained German engineer,
What chance does a tin basher have,
It’s not fair

Relax. Just a process engineer. I know something of everything, but nothing really well [emoji12]

I already broke the rule twice, not going for a hat trick
Might be able to sneak it in at a later date though

Maybe we need a different brand jigsaw

Im still waiting for the zen to kick in, I suspect it won’t be long now

I would love to blame the jigsaw, but immmm I think for me it was wrong blades wrong place wrong attitude.

I also don't have any marking fluid (not that I'd need it for my plane build), but I found that felt-tipped markers work well enough in a pinch, too.
