What is the easiest method to sand varnish sour a wood door? I think sand by hand would purloin forever. Can anyone...

I think sand by hand would purloin forever. Can anyone recommend a cheap sanding maching and what sort of sandpaper to use? Is it really messy? I am a DIY virgin hate the prospect of having to do any of this!!
We bought our home 1 year ago and have the same problem. I spent time on research to do impossible to tell apart, and worried about ruining the inherent hardwood floors or scoring the wood by making a mistake, not to mention overstaining or making a mistake. This was one of those things we feel was too big an investment to try ourselves.

Since you are a "DIY virgin", i would recommend taking bids from a professional company to come contained by and at least strip/sand the floors first for you. You could other varnish it yourself. The cost we paid is in the order of $2.25 to 2.50 a square foot (and that was for the sand/stain/sealer). Plus some companies own dust-less machines, meaning you won't be forever wipe up everything.

The result was certainly beautiful hardwood floors that everyone rave about when they enter our home.

Hope this help!
Hand sanding is a drag - the easiest track is to take it sour and get it dipped contained by a caustic hip bath. You can probably find somewhere in Yellow Pages - the ending time I had any done it cost a tenner respectively.
The only point you need to be carefull next to is the glue holding the door together - if it's animal base glue the hip bath can sometimes dissolve it. If the door's fully jointed ie no glue next you've no worries. Wherever you take it for dipping should know how to advise you.
If you opt to sand it instead get a small head sander. If you get a big 1/3 sheet sander you may consider it's going to be quicker but you won't get ample pressure on the work piece. I use a Bosch PDA 180E and it's excellent. As for the intricate bits such as in the door panel mouldings I'm afraid there's no substitute for steel wool and lots of elbow grease!

Good luck
Answers:    Pick up a 5" unselective orbit sander. You can get one starting around $30-40. Get the sympathetic that uses hook and loop disks, rather than the stick-on type. Then you will want a roll of 60 grit disks, a package of 100 grit, and a packet of 150 grit. Start with the 60 to remove the bulk of the varnish. Then use the 100 to smooth the door more, and finish next to the 150. If the door is a flush door (no raised panels), mind your Ps and Qs. The finish layer of wood is strong veneer, and it's very unforced to get carried away and sand through it. Hope this help.
If it's really Varnish and not Polyurathane, use Denatured alcohol or Solvent alcohol. You can buy it at any hardware store. Wipe it on with a scarf and the varnish will get gluey and then run a dry rag and wipe it rotten. You'll have a dazzling like alien finish and you can re apply the varnish or put polyurathane on it. What I would put on it is tung oil. It's glib and a nice finish.
