Challenge 2020-2021 CKlett - Scraper Plane
Hi,
I had bought a Veritas scraper plane blade a while back for my Stanley 12 1/2. But it is just a hair too thick for it, so I decided to build my own scraper plane around it. Hence my queries about the pine. It does not necessarily scrape well.....

After some research and seeking inspiration on the web to what style and look I might like. In light of to maximise the challenge for me I decided to make a dovetailed infill version. And I will try to come up with a way to also incorporate the blade tilting functionality of the Stanley 112 plane. For the mechanism I have already some thoughts and will follow them up with some mock-ups and prototypes to make sure it can work.
Anyway, here is a first concept drawing. Dimensions and proportions are not fixed. It is just a starting point and I am sure it will still change and evolve.

Also not sure if I will make the sides curved like a coffin style or keep them straight. The latter would be easier, but then again this is a challenge.....
I might also build another plane in parallel I have in my head to practise some of the techniques further.
At least I do not have to worry about mouth opening on this one

I'd say that is challenge well and truly accepted CK! I'm starting to feel like I'm aiming too low .

My worry is that I might be aiming too high. It reminds me a bit of these cooking competition shows. There is always a team who think they can make a slow cooked roast in 60 minutes. They get something on the plate, but it is not that great. And sometimes doing something more simple and executed properly could have been the better choice.
I hope I am not one of these teams

The counter sounds like a good idea. I think we should have an extra prize for the quickest plane built. people have 3d printers and metal working tools. Can I just make a simple wooden plane?
I am learning, slowley.

Pagie, not to sure about an extra prize, but we will be looking for donations in a few months
A simple plain ?? It can be as simple or as complex as you like - mine will be simple.
Cklett, If you are still concerned about using pine, I have a simple solution - submit images of 2 shavings- 1 1 using pine and the other could be any timber of your choice.

Or I could sell you a shaving.

Finally I got to do a bit more on planning my design.
I decided to start with the frog and lever cap. For that I copied the parts from my Stanley 12 1/2 on some cardboard to get dimensions which work. I might still change the top shape.
The frog I make out of steel and the lever cap shall be brass.
A few details to think about. The majority of the frog is 6mm thick but wherever it is connected to the plane body, lever cap and adjustment bolt it is about 15mm thick. The original is cast. I will have to use rolled mild steel. No mill so I cannot start with a 15mm thick blank. Unless I decide to use a 15mm thick frog all around, which might become heavy.
Alternatively I can use a 6mm blank and habe to weld some pieces on where I need more material. Or come up with a bolted design.
Next week I will go and get some material.
Cheers

Another option for joining metal is solid rivets,
I did that on my plain iron for my mitre build.
It’s really not that complicated, just drill through both pieces of metal clamped together, I use a three mm hole,put a small countersink on both faces.
I then use a 3 mm bright nail cut to be about 2 mm longer either side of each face.
Push the rivet through(Cut down nail)
And peen one side then the other, and repeat.
I find after one or two rounds of peening to file then flat but still proud an peen again then file flush.
Have a go on some scrap first,
It’s more complicated to explain it then to do it.
It will take a keen eye to see the rivets once finished.
Cheers Matt.

Thanks guys. I decided I will first go for chunky and use 12mm thick steel for the frog. If I don't like it or gets too heavy I will go for the riveted version.
Also I have now enough material together to start.
You see two blades. That's because I plan to build a scrub plane in parallel. That's going to be my practise plane for dovetailing and infill.
So I will first practise on some scrap, then the scrub plane and then the competition plane ;-)
