Thanks!

I always have trouble with the second coat tending to have runs even with sanding before the second application

Runs are usually due to too thick application.

Good stuff. That "curing in the cold" thing is the biggest drawback I see with them, although a lot of folks really grump about the grain raising (not me, no big deal).

"bury the grain."    Let the first coat raise the grain.  It's up and stiff, knock it off with P400 sandpaper and maroon Scotch-Brite pads.  No need to "pre-raise."

I guess I should add another warning.  Oil, varnish, and mineral spirits are widely compatiable.   Mix in whatever proportions you want.  Dump in a thinner to reduce viscosity of varnish, add enough and you have a wiping varnish.  Mix oil and varnish to make an oil-varnish blend, add thinner to make a wiping consistency.   Buy some Danish Oil and add some varnish to make it a more film-forming finish.

 

Not so fast with water-borne finishes.

 

W/b finishes are delicate balances of up to a dozen components.  You can't always just add some water, glycol ether, resins, colorants, surfactants, or de-foamers and expect them to work as designed.  Some mfrs offer a thinner, some do not.  Some you can dump in selected stains and make a toner, some not.  Remember the rule -- if you have not done it before, test of scrap before you put it on the top of that table you've spent 100 hours making.

Who We Are

Operation Ward 57 Challenge Coin Display Project

We are a woodworking community with an emphasis on sharing and learning the skilled craft of woodworking and all of its related disciplines. Our community is open to everyone who wishes to join us. We support our American veterans and active duty, being a veteran is not a prerequisite to join. Join us now!

Objective

Air Force Command Center Plaque

Of course just like most online woodworking communities we are centralized in the arts, crafts, and trades that are woodworking. But, we have another focus in our Patriot Woodworker community, we are the only woodworking community that was founded on our care and concern for our disabled veterans.

Volunteer

Patriot Woodworker Volunteers

The Patriot Woodworkers are an all volunteer community, from the staff and hosts who run our online woodworking community to the members who frequent our forums, you'll find volunteers in all of us. We are not on a payroll, unless you consider the spiritual rewards gained from volunteering, as compensation.

Education

Logging

One of the many projects we are working on is a wiki for our online community. A wiki is a great way for woodworkers and enthusiasts to share their knowledge to others, and to impart their knowledge for others to learn from, and utilize as well for their own benefit. We hope you'll consider being a wiki contributor.
