It could very easily be a shop built measuring tool built for a specific purpose.

Not too much turpentine, it can cause problems if you use too much. I'm referring to brushing, I've no experience of spraying Shellac. You can also use Spike Oil of lavender, which does the same thing. Smells nice too.
Brushing shellac, which is really called spirit varnishing, is not an easy skill to acquire IMO. It's certainly no easier than French Polishing.

I have used Blum without the guides - the locking devices are very simple - they fit snugly into the front corners. The rear hole is pretty easy too. Just install the drawer on the slides and mark where the slide connects to the drawer. Drill holes in the drawer back.

I don't remember the exact measurement, but after you mark the first drawer, just put the holes in the same place on all the others.

I would probably hit it with a quick coat of BIN primer after I sanded.
It will seal up anything you might miss and allow you to fill any bad spots before paint.
It's great paint but watch it on the verticals, it really likes to run if your not careful.
By the way since its a 60's house you should absolutely put a tent over the entire house , wear a haz-mat suit and contact 3 or 4 government agencies before you sand.

I know what you mean. You just show sandpaper to that stuff and it sands through.

My guess is that most oak plywood will be that way. I know appleply and sandyply have thicker skins but those are paint grade.

About the only thing I can say is try a real lumberyard.

The wood of a thousand names, and appearances. Gum, Liquidambar styraciflua, is a tree that grows in many places in our country, and possibly why it has so many names. All lead back to it's scientific name though. Cutting it is fine, planing and jointing it is sometimes a challenge due to an interlocking grain.

For comparison it's Janka hardness is 850 so it's just softer than Soft Maple, and Cherry who come in around 950.

From whom did you buy them - and have you called them?

I like Flickr. It's easy to grab links to drop into forum posts and you don't have to worry about resizing the image. Just pick the size you want and grab its link. (If I remember correctly, you can do that in Pbucket too.) Cropping, if you need to do it, is also very easy.
