Dacron IS polyester; it's just Dupont's trade name for polyester fabric. Also used for aircraft covering under the trade names Ceconite, Poly-Fiber, and others, but it's all just polyester fabric.

No, it's a ruling pen. This is the one from my set, part of one of the compasses: You set it to the line width you want and use a dropper to squirt some ink in between. Surface tension holds it there and it's drawn out when it touches the paper. Tricky to use and easy to end up with a big...

Not sure which bit you're looking at but there's no metal scribe. There a couple of ruling pen tips, and the points on the dividers are for transferring measurements from the scale (ruler) to paper.

Probably not a big deal here; I imagine most people are posting their own images rather than from the web... unless it's in image in their own cloud storage.

I don't remember if it was an earlier version of Xenforo or another platform, but when inserting an internet image there was a checkbox to link in place or copy the and reference locally. Might be a feature that can be enabled? When storage was more expensive many admins preferred to reference...

I was speaking mainly of copy-pasting an image from my computer. But from the internet, if you copy-paste the image, it will then reside on this server. If you copy-paste the link, then yes, that link could break. Rightclick on an image in Firefox and get: But, if I copy-paste the link...

My new old Royalex canoe sure weighs less than the old 1960s fiberglass canoe that trashed my shoulder last fall! Re throwing canoes from roofs, there was a story some years back about a canoe that came loose from a seaplane and fell a thousand feet or so. When they finally found and retrieved...

I generally just use copy-paste to upload images.

I have and often use one of those, though it's not as nice as yours. That level of technology just means less to go wrong, and it lands so slowly you're unlikely to get hurt. They used to say, "The Piper Cub is the safest airplane in the world; it can just barely kill you."

This is Dad's compass set, purchased when he was in college in the late 1940s. I used it during the first part of my own engineering career (early 1980s) until CAD took over. Every once in a while I pull it out on the rare occasion it's easier to make a paper drawing.

I still have one somewhere. Think I last used it around 1982.

Late 1970s, calculators were ubiquitous, but I still carried my slide rule to important exams... saved my butt once. Still have one (Dad's) and still use it. Got one of those too, in an inside pocket of my flying jacket it keeps me warm flying my open cockpit biplane in cold weather.

I wouldn't suggest a softwood like pine. It might be strong enough across the middle of the board but I'd be concerned about strength around the fasteners at the end of the thwart. Sitka spruce is the standard for aircraft construction but is getting hard to get; Douglas fir is an alternative.

My sisters and I in 1965. I still own this canoe.

When looking for something else I pulled a box of photos out of the attic and found this... it's my sisters and I in 1965 in the very same canoe. I was 5, my sisters were 10 and 14. It looked a bit better then...
