How Do You Sand? From WoodCentral
Like many woodworkers, the
originator of this discussion thread describes himself as "not a
fan of sanding." For his current project, he's managed to pass off
– er, "share" – the sanding duties, but he wonders if other
woodworkers have methods that work the best for them. - Editor
"I
am not a fan of sanding. I have a Performax, Portable belt sander,
ROS, Drum sander for the drill press, a 6x48 belt sander with 10"
disk (new to me and not a lot of time on it yet) and lots of
sandpaper. My son is participating in the building of a bed for him
and his wife. I have (happily) let him sand the headboard. He thought
he had it in spite of my protestations. Applied the stain and
realized he needed to start over. (hee hee) Scraped with a hand
scraper, sanded with a ROS. Incidentally, I call the first coat of
finish The Reveal. If you think finish covers any mistakes, you are
mistaken. Finish just reveals the flaws. So, how do you sand? Large
flat surfaces? Edges of table tops? End grain? What machines have you
found useful? Do you scrape first"- Barry I.
Some
respondents interpreted the poster's question literally, answering
how they sand in their own shops. - Editor
"So
far as sanding goes, I run most projects through the widebelt sander
where I work, then smooth them with a 604-1/2 Bedrock plane. I don't
normally sand after planing. Occasionally, some spots have small
tearouts, but I generally will just leave them alone and they are not
noticeable after finishing if you don't mess with them. Occasionally,
I get bad tearout; then I will scrape that area then hand sand the
whole piece with 150-grit."- Moses Y.
"While
I'll admit to my big, stand-mounted combo sander, one of my
most-reached-for tools is my big, black, rubber, babby-buggy sanding
block. I'm never really sure if I should be ashamed."- Steve M.
"I
don't have a wide belt sander, and am unlikely to get one, due to my
age and shop size.The equipment I use is a combination of hand
sanders, ROS, Orbital, and felt block, hand-powered. I especially
like my 1/3 sheet orbital, which is an old 'Skil.' I've had it for
years, and it is slow. But on surfaces like glued-up chess boards,
it's great at leveling out slight differences between and among
squares. I can finish up with a very light SOS and 220/320 paper. I
use the natural wood as God's colors. I couldn't be without my little
Ryobi spindle sander when doing flat work or making patterns, say,
for curved clock moldings, chair rockers, curved brackets, etc.
However, the most exquisitly designed sander in the whole universe is
my own hand. It works perfectly every time, given enough time." -
George
While
others took a broader interpretation, offering sanding advice in
general. - Editor
"As
with most process questions, the answer to this one depends on the
desired result. I'd first ask what level of perfection are you after?
That will determine how much you care about a dead flat surface. And,
what finish will you be using? Film finishes, such as lacquers and
varnishes, don't require as fine a grit as oil finishes. As to what
equipment you should use, if you want a really flat surface, consider
finding someone with a large wide-belt sander. In a few minutes, you
can have a really flat surface ready for finish sanding. If it costs
you money and time to schlep that monster to the nearest wide-belt,
it's probably worth it in terms of the nice flat result and the lack
of aggravation and grunt labor you'd need to go through otherwise.
"If
you need to flatten a large solid-wood panel by yourself, the first
thing to do is check the surface carefully for flatness with long
straightedges, then take down the high spots with a hand plane. You
can use card scrapers (or cabinet scrapers or scraping planes) to
remove any minor traces of your hand plane. You can leave it at this
if a scraped surface is to your liking, or you can commence sanding.
I generally go to a 6" ROS with an aggressive enough grit to
create a uniformly sanded surface in relatively short order....Move
up through the grits until you've gotten to the level of grain
clarity you want, making sure to completely get rid of evidence of
previous grits. If you're planning to use any water-borne products
such as stains or top coats, moisten the surface with a wet rag, let
it dry, and then sand very lightly with your fine grit paper to get
rid of the little nubs and fibers that were raised by the
water....Anyhow, that's how I do it." - Ellis W.
If You're Planning a Hobby Shop
from WoodCentral
Like many woodworkers, this one is
dreaming about his ideal shop. Unlike many, he gets to actually build
it – and he's asking for input from others. - Editor
"I'm
building hobby headquarters in 2011, and I would appreciate some
advice. North central Arkansas. Looks like the new building will be
44x32 with about 12x32 lost to a boat/RV bay. That leaves about 1000
sq. ft., but it's a bit square, which limits the perimeter length.
Maybe I should go 48x32. Inside this shop will be a small
dust-limited corner 'office' with heat/ac. Wood storage is in a
separate shed. For my infrequent HVLP spraying, I can empty the bay
temporarily.
"Thinking
10' ceiling for the shop part. Drywall ceiling & lots of lights.
Wondering about flooring and elevation stuff! Concrete floor for the
bay and wood floor for the shop? But the building site is quite
level, so to allow support for a wood floor there's going to be a
couple of steps up from the bay or from outside, right? Isn't that a
problem for material handling and general in/out? I was thinking a
garage-type rollup door for both bay and shop, but now I'm thinking
of omitting the one into shop. Shop will have dust collection, but I
don't know that I have the planning foresight or drive to put it in
the floor at the right locations. Plus all my tools have wheels.
"All
is variable at the moment. A friend once told me that he made the
mistake of building his shop after his house had depleted too much of
his money, and the shop suffered. So I'm doing it the other way
around. The shop will be completed before we even break ground on the
house." - Ron
The
first respondent had a suggestion that was a bit out of the ordinary.
- Editor
"Have
you considered a pre-engineered metal building? Just thought I throw
it out, because pre-engineered buildings are something most people
might not have considered as an option. and you have a lot of
flexibility with door/windows/skylights/garage door placement." -
Rob C.
Some
discussion in the thread took on the topic of the shop's floor. -
Editor
"I
have an wood floor in my shop area - the concrete slab was recessed
to allow a 4x4x4 oak block laid end-grain up - best shop floor I ever
had!"- Rob C.
"I
stick built my shop and, for your floor, I would suggest what I did.
In the shop area, lay down treated 2x4's flat, on 24" O.C and go
over this with 241 plywood , which is 1-1/8th inch thick and finish
off with a durable flooring like linoleum or, like I did, tempered
Masonite cut into 15-7/8th inch squares and coated with a two-part
epoxy paint. Been in use for 12 years with no visible wear and easy
on the legs and feet and warm in the winter when the shop is heated.
"There
are many reasons why a wood floor is superior to a concrete
one...Wooden flooring is warm in the winter; concrete isn't. Wooden
flooring will not ruin the edge on a edge tool or destroy anything
that a trip to a concrete floor will. If concrete was equal to wood
in ease of standing, then the floor mat companies would be out of
business. If you fall on a wooden floor , you will be glad it was, a
concrete one on the other hand.... If you need to fasten a machine or
fixture to the floor, it is a piece of cake if it is wood, not so
much if it is concrete. Your wooden floor will not develop shrinkage
gaps or heave in cold weather if a dummy put it in: wooden floors are
forgiving of weekend warrior types learning the hard way.
"Lastly,
a combination of both types as I have described is the best of both
worlds and you would be glad to have one." - Fred D.
"While
joist floors are maybe easier on the feet, definitely easier on the
do-it-yourselfer's wallet (but not cheaper if you're hiring a crew),
in the meantime I've traded a debt owed to me for a 12" jointer
that weighs about a ton. Now it's a relief that I have the concrete
floor...concrete's good points for a workshop outweigh its drawbacks.
If
you decide you want wood after it's done, its easy to retro-fit as
Fred describes. Do the tall walls and scissor trusses also, and
you'll even have the head room to put dust collection and electrics
in the floor if you so desire. Personally, I find 10 walls a waste of
effort, but the ability to raise the shop floor like that would
definitely counter the waste distaste." - John
Also
discussed: doors and walls, lighting and power – and more. - Editor
"You
will never needs to pass into the shop with anything that won't go
through a standard entry door. Such doors seal in heat and cooling,
as needed, and seal out heat and cooling, humidity and rain. I am not
fond of drywall walls in a shop. Walls are to hang stuff on. - Bill
T.
"Drywall
walls in a shop work great. I painted mine white and it improved the
light levels noticeably even though I have a decent number of
fluorescent fixtures. I put french cleats all along one wall to hang
stuff on. The other walls have lumber racks, upper cabinets, tool
storage, etc."- Chris F.
"I
have a garage door on my shop. It leaks energy, but it very useful.
The table saw is 16' from the rear wall and about five feet from the
overhead door. I can rip a 16' board easily by opening the door and
letting the board go out into the driveway. The width of the door
pays off occasionally when cutting plywood. My point is, think about
what your projects might be and allow [room] for them.".- Barry I.
"If
you intend to do any detail work – carving, hand-cut dovetails,
etc. – you will need excellent lighting, and more so if you are
retired. I could 'arrange the furniture' in any size or shape of shop
to build fine furniture, but not if I couldn't see scribe lines or
shadow on a carving. It takes a boggling amount of fluorescent
fixtures to equal the light coming in a large window. A typical large
lighting store will have a computer program to determine lighting
requirements for a given size and shape. While new and uncluttered,
paint the floor (and walls) a very light color. It will reflect light
otherwise lost from above and boost illumination more than adding
several more fixtures." - Bill T.
Some
respondents shared how they'd addressed these issues of setup in
their own shops. - Editor
"Lighting:
We have a 24' wide shop with 3 rows of florescent fixtures running
end to end the length of the building. Light levels were between 100
and 150 lumens, which is bright but ...you are never in shadow. We
did go with a warmer lamp to help the color of things look better.
"Floor:
We are in an existing building that is mostly concrete and have many
rubber mats. Your legs feel it by the end of the day if you don't
stand on them....For the walls, I would lean toward OSB just because
I tend to bump into them. Plywood under the [gypsum] is a good
option.
"Doors:
We have a double door into the shop which is handy. Residential
overhead doors just don't seal. A compromise might be to have an
overhead out to the boat bay. Make sure if you do have an overhead,
you also have a man door next to it to minimize its use.
"Power:
You can never have enough power. As we are in an existing building,
ours is all in surface conduit but we have outlets every 8' around
the perimeter with multiple circuits. I put in a few 220 outlets but
have never used them. All of our large tools are hardwired."- Ryan
H
"I've
read through most
of the responses, and thought I'd weigh in. I 'completed' my shop
last year. It's a stand-alone in my backyard, and had a few years of
thought that went into the planning before ground was ever broke.
I'll touch on a few things here...
"At
least
10' walls. And a vaulted ceiling adds a much more 'open' feeling.
"I
recommend at least framing for a garage door in to the shop, but
installing a double door. The double door is more than enough, seals
better for insulation purposes, and doesn't take up as much valuable
wall space. And, if you decide to install a garage door, you won't
have to re-do any of the framing...
"Plumbing.
Install a bathroom with hot & cold running water. Electrical --
Lots of outlets, and that includes putting them in the floor. Nothing
worse than building a new shop and still
tripping over extension cords... Oh, and don't forget outlets in the
ceiling for air cleaners.
"Dust
collection - Put it in the floor - See above. Locating the ports
isn't all that difficult if you already know 'how you work.' Lay out
your tools, either on graph paper, or use one of the many online shop
design programs, and calculate distances from the walls. These don't
have to be exact, but they do need to be relatively close. I brought
power up through the floor in the same locations as the dc.
"Floor-
I laid a wood floor over concrete. It was worth every penny. Walls- I
was a volunteer firefighter for 10 years. I saw several fires where
drywall saved the house. To make it so I could hang stuff wherever I
wanted, I covered the drywall with 3/4" t&g cedar. And 5/8"
drywall on the ceiling.
"More
electrical - Think ahead for security, sound system, tv/radio,
internet, telephone, etc. Insurance - Talk to your agent about
insuring the new place. Some companies are a bit fickle when it comes
to insuring woodshops in regards to heating and whether or not they
'make money.'" - Dave
