Why? What's the difference between having an 8"long bed jointer, a 12" table saw or a plasma cutter? Remember members of the metalwork forum have also been invited to participate in the challenge.
For the record I have such a jointer and table saw in my shed and have had for well over 10 years

I fear the jigsaw will possibly be hopeless here Paul.
Not having a plasma cutter or any gas cutting equipment,have you considered joining the dots,well technically joining the holes,
(Drilling a serious of holes)
Tho to be fair that’s a few holes per side.
I wouldn’t want to be in your shoes doing that.
I’m impressed your still bitching and whinnying at least your sticking to your game plan.
Cheers Matt.

One of these would be the go. I cut a piece of railway line on mine last week.
It also has a table so it can be used vertically like a woodworking bandsaw. I don't know how I ever did without it.

Brad, Bob and Matt
You all make excellent points and I think I could argue favourably for each of you.
My plan at this point is to cut as close as I can a series of straight lines with a thin cutting disc on my angle grinder and then use the same tool fitted with a grinding disc to remove the curvy bits (primarily the inside curves). I will finish up with a flap disc in the aforementioned angle grinder before using a file. I will make up a timber template to avoid "overdoing" things and to get the sides exactly the same.
Perhaps Bob's comments should include being "performed by yourself" as opposed to having another person perform the operation. Ie. contracting out. The exception being the purchase of a finished blade, which most of us will be doing.

I have access to a metal cutting bandsaw at work, but it will only cut straight lines. I could probably get a narrow metal cutting band for my bandsaw, but that would involve parting with money and one of my criteria is to not spend significant money on the project and utilise materials I already have minimising even the use of consumables.
That pretty much restricts me to buying a bit of W&D paper and a new power tool particularly flaunts my own criteria. (Much as I would like to have one and somewhere to keep it)

Paul, your channel is wider than I've used to date, but I managed to cut the rough shape out of some 2 inch channel with hacksaw & files. You do have to keep a close eye on the far side to make sure you aren't going over your lines! Anything that gets the bulk of the waste off quickly is for me. I guess the old angle grinder gets rid of waste quickly too, but might be a bit risky in the wrong hands (like mine!), it doesn't allow a lot of room for error - at least you go astray more slowly with the hacksaw. Some appropriate files should get you to a nice finish..
Cheers,IW

For the "sinners" among you, I was not contemplating cutting both sides at the same time and I agree that, if that was done, a very careful eye would need to be kept on the far side. I don't think I am capable of that as the 75mm span would be a fatal test of my hacksawing skills. Instead I will put my faith in some careful marking out, a single template to be used on each side and the faithful angle grinders equipped with thin cutting disc, grinding disc and finally flap disc before going to files.

I don't think you'd find the hacksaw all that difficult, Paul, you only want to cut "close enough" to your lines. I'd try both approaches myself & see which gave me the best return of speed vs control. I well know that I can run off the line a lot quicker & a lot further with the cutoff wheel, but I think you've had a lot more practice hacking things up with the wheel than I have. I mostly use it for straight cuts against a guide and only very occasionally attempt 'freehand' cuts.
I've been meaning to have another go at making a plane body from channel, out of curiosity and with a view to adding that technique to my "manual". My first attempt was a bit of a flop, but I did manage a reasonably successful thumb plane using some brass channel, a couple of years ago: Vers2.jpg
I meant to show you this last night - it's a precedent for your "channel plane": 3 plane bits.jpg
My dad & his cousin made it back in the '30s, and I think it's instructive of what you can do with very limited gear & time on your hands. His cousin worked at the local sugar mill & I presume he had access to the welder to attach the "frog" and nut for the front knob (it's certainly not a professional job!): 2 Frog weld.jpg
It is hardly a paradigm of the plane-maker's art, but it works in its rough way & would make a good scrub plane. I was once tempted to "fix it up" & try to refine it a bit, but decided it's far better left as-is as a testament to the ingenuity of that generation in tough times...
(Sheesh, you're a tiger, still up & posting at 11:23 after a longish drive - been a few years since I had that sort of stamina!)
Cheers,IW
