Hijack!

[treeslayer]

Thanks Coop, yeah just start and stop marks on the fence and on the board, I use my dado stack both ways that you have shown with no problems whatsoever 

[Coop]

Thanks Dave. I had heard that you weren’t suppose to do that on a router table. Just wanted to make sure and be safe!

I put my snowblower away in hopes that it brings a blizzard. We didn't get enough snow up here IMO.

Ahh Drew speak for yourself 

We had plenty and it was colder then it needed to as well LOL

...and with that guess what its snowing but high of 50 tomorrow so it wont be here long 

[Coop]

Is it global warming or mother nature at her usual? I covered my tomato plants 2 weeks ago due to a frost for the first time ever in March.

Wouldn’t the bit be spinning the opposite way you wanted it to if you moved the fence behind the router and ran the piece in between in the normal right to left direction?

[Coop]

Has anyone used B-I-N, Bin Zinsser shellac primer? I’m making a table and using some leftover 3/4”  red oak ply for the top. I will band it with some hard wood and would like for the grain in the ply to be as unnoticeable as possible. The new owners will paint it. 

[wtnhighlander]

I have @Coop. All I can say is, brush fast! That stuff dries in a hurry.

[Coop]

Does it help in the grain fill? 

[wtnhighlander]

@Coop, it probably would fill the grain completely if you applied it with a squeegee. Dries quick and sticky, so prepare for the mess.

[Coop]

Thanks Ross. Not that the recipient, a 12 yo fellow would ever notice. Just wondered for future hardwood uses. Thanks to you, I think I will pass and save a couple of bucks and hours of labor! 

[Mark J]

Why not use one of the grain filler products?

[Tpt life]

I love it as a cover stain. It does not dry any faster than other primers I have used. It can pore fill small pores. 

[wtnhighlander]

Hhmmm...maybe the can I used was bad, or maybe it was a hot weather issue, but I couldn't lay that stuff out of the brush fast enough. Seriously, the bristles were getting crunchy at the top of the dip line within minutes of starting the job.

[Coop]

I’m a day or so away from doing the top, so may consider using it, if they sell it in a quart. 

[Tpt life]

Ross, that is how primers work in general. They are not made to flow cover or build film. They are designed to bind and flash off so that film building happens uniformly without as much bleed through. 

[Robby W]

The Zinzer shellac based primers use alcohol as a solvent, so they can flash off quickly in the wrong conduit. Maybe adding a retarder will help. I solve it by spraying.

[Coop]

Is it sprayed like any other shellac?

[Robby W]

Yep. It is shellac with coloring. Shellac makes a great primer because it will seal almost anything. Although I can say that it won't seal cat urine loaded flooring in one coat...

[Coop]

Can a waterborne paint be applied over it?

[wtnhighlander]

Being shellac based, it should. I would check the label instructions first, just to be sure.

I’ve heard about doing this, never wanted to try it and this proves why I’ll never try it

I just watched it in an episode of Making Fun (kids show) on Netflix with Jimmy Diresta where they did this. They didn't go into any of the details about the process but I suspect they doing it with a car battery type of setup, not a hacked up microwave or whatever people were using.

You can use a car battery as an energy source, but the voltage must be boosted to dangerous levels in order to burn the tracks in the wood.

[JohnG]

Yes, 12v won’t make long tracks like are desired. 
We used to pull flyback transformers out of old CRT monitors and TVs to get ~30k volt arcs to zap things. Probably lucky that none of us got hurt.

[wtnhighlander]

The need for higher / dangerous voltages can be reduced by treating the wood with an electrolyte, like salt water, and simply keeping the distance between electrodes short. It takes volts to overcome the high resistance of a long-ish path through the not-so-conductive dry wood surface, but once the circuit is established, only a few volts are needed to produce enough current to char the wood.
