Re: Drawing curves

this site is close to helpful, but it looks like the circle radius is limited to something like 36 inch

Re: Mixing water borne finishes - ¯\_(ツ)_/¯

the finish appears to be fine - BTW.
it looks just the same as the boards finished with just Helsmman, and these have been sitting in the sun during the day since i coated them, and the finish is hard but not cracked.
considering the application, i think i'm totally good to go.

Re: Mixing water borne finishes - ¯\_(ツ)_/¯

the patio cover will have a solid roof, and these sticks are all roof support structure under that solid cover - so i figure its worth the gamble. and they will be 9-10 feet in the air so as long as the finish stays on i'm good.

Mixing water borne finishes - ¯\_(ツ)_/¯

so i did a crazy thing. i'm refinishing a patio cover. the main redwood frame is nice and sound - and looks good because its been standing, protected, for 20 years. i've stripped the old oil - i think i used Penofin on it years ago - maybe twice. can't get Penofin in CA anymore so i'm using ...

Re: Restoration of a 1931 Martin 00-17

2nd Barry - that is amazing.
I get it tho - must take a bit of fussing to get everything laying down, and to figure out where the few clamps need to go.

Re: Restoration of a 1931 Martin 00-17

Squeeze out - good question, i've really not had many problems with drips going down the inside of the box. I usually use reverse kerfed lining, and that stuff invisibly soaks up glue into the hidden kerf tunnels. The place where it does come out is where the brace ends fit into pockets in the linin...

Re: Dark spot in sap wood

3rd that.
i'm with Ryan & Brian.
Knots and bark inclusions and spalt-ish mold stains and worm hole - i'm all good with. Those are natural.
those stains are from stickers that were incompatible with walnut - and i would reject that wood.

Re: Restoration of a 1931 Martin 00-17

I'm a bit late to the party here, but let me explain what i do and see if anyone cares. I also use HHG for gluing tops/backs via go-bars, and for a long time I glued backs to rims with the back down in the dish. Even with a complaint layer in the dish I would always get gaps in the joint that bugged...

yes - you can make your plastic goo with ABS and acetone (tho I think ABS is dissolved more easily with MEK (which is nasty stuff))

Re: Renaissance Wax

Hey Bob, I don't think it "reacts" with lacquer. Meaning that if you were to apply it to lacquer, then strip it off with mineral spirits, the original lacquer surface (from under the wax) would be totally unaffected. I think you can apply it with confidence. I would expect the same from a fresh lacq...

Re: Restoration of a 1931 Martin 00-17

keeping the back was just my $0.02 - you guys covered my same thoughts very thoroughly in your discussion. in the end - it be what it be - and i'm sure Barry will do a great job.

Re: Refretting a Guitar with "Contoured" Binding

that's what i was going to say, but wanted to hear from a more seasoned repair guy would say. leaving plastic nibs at the end of the frets just seems so ridiculous - why?!? must be the manufacture process.

Re: Restoration of a 1931 Martin 00-17

sounds like the sides were fully oxidized through-and-through. there's no coming back from that. thing is, the back is probably the same so watch out!

looks like you left the binding stuck to the rim of the back - what you going to do about that?
