Photo 2, attached (I hope!) shows the piece I need to make. The first photo shows where I plan to use them - if my wife approves of this design. (I have 197 feet of slantfin metal heater cover to replace).
The inuksuks are 8.5" long, about 2" wide with a 5.25" x 3/8th inset on one side. This has to be fairly precise because it's where the radiator cover fits. The other side fits what's left on the wall after I take the front cover and louvers off the radiators. (As it turns out I can't fully remove the metal work because this would require removing the top strip of cedar and it's so dry it cracks and breaks easily - plus they countersunk the nails holding these boards.)
I made these two out of scrap using a handsaw - they're just a proof of concept thing for my wife to look at.
However.. if I use this design, i will need to make about 60 of them - and they all have to be better than these two. So how? What's the right tool for this?
And.. is it worthwhile trying to cut them out of one solid piece? or would making them by gluing together rectangular pieces cut to shape on a saw work just as well?
