Im stripping a Buffalo Forge Co. #18 drill press in preparation for
making Mucho Macho Drill Press #1
(1hp, MT3 spindle, VFD)

Ive used StripEez paint stripper, but some of the old filler will not
come up easily in the corners and crannies. Ive cup brushed where I
could, and still cant get into some of the tight places. The biggest
media I have for the blast cabinet is 40-70 crushed glass and its
taking forever to remove the paint/filler

Will I have better luck with sand?

I would avoid using sand for a number of reasons, silicosis being an
important one. Besides, sand is not particularly aggressive IMO.

I'd be tempted to try "Black Magnum":

http://www.consolidatedstripping.com/pages/6/index.htm

I've never used Black Magnum, but I've been curious about it ever since I
first saw an Ebay listing for the stuff a while back: it looks like good
stuff.

Here is a description of Black Magnum from another distributor's web site:


The only reason I haven't bought some yet is because I bought a fairly large
supply of aluminum oxide before I came across the Black Magnum listing.

If you get some of this, let us know how you like it.

Maybe the most effortless way to remove paint and fillers is with high heat.
A propane torch (or almost any flame) will soften and blister it almost
instantly.
One needs to avoid breathing the stink, it's most likely very nasty fumes.

An improvised scraper will get thru deep coatings quickly with the aid of
heat.

A solvent scrub of the stripped areas should be adequate for refinishing.

Media blasting soft materials is generally slow as the impact of the grit
seems to be reduced by soft materials.

Im not concerned about silicosis at this point..I have a 36" x 48"

Here is a description of Black Magnum from another distributor's web site:

Quote:

Coal Slag product that is very angular and contains less than 1% free silica. Black Magnum is available in coarse to extra fine sizes. The hardness of this material makes it very resistant to material breakdown. Advantages: - Does not react with coatings so there is less coating failure - Does not draw moisture - After-job cleanup is fast and easy - Low free silica content

The only reason I haven't bought some yet is because I bought a fairly large
supply of aluminum oxide before I came across the Black Magnum listing.

Im looking for something with some mass to it. If I had enough steel
shot Id try that..but...

These are heavy cast iron castings with the typical shellac type
filler under it.

Ill check locally for the Black Magnum stuff..as Ive got several other
projects that will need something gnarly to blast down to clean metal.

Yes, you mentioned you had a blast cabinet in your original post. But even
blast cabinets leak dust. However, since you're outside, probably not too
much of a concern. You can always wear a respirator.

Consolidated Stripping (the company I linked to in my earlier post) sells
Black magnum on Ebay:

http://cgi.ebay.com/ws/eBayISAPI.dll...tem=4349506203

Just $13.95 for 10 lbs, with free US shipping. They also sell 50 lbs bags on
Ebay. You can choose from several grit sizes, including 6/12 which has got
to be like pea gravel!

But if that's not heavy enough for you, they also sell steel shot blasting
media:

http://cgi.ebay.com/ws/eBayISAPI.dll...tem=4349506591

$15.95 for 10 lbs, again with free UPS shipping. (50 lbs bags also
available.)

Disclaimer: I have no interest in this company, and in fact, I've never done
business with them. But they seem to have some good products at a decent
price.

D'oh! Damn...And I didnt even think about using heat....blush..and I

I worked at a Sandblasting shop for almost 10 years and trust me if you
get Sandblasting Sand there is not any silica in it anymore, that has long
since been removed for health reasons. However if your serious about the
blasting and want something that will last a long time look at aluminium
oxide. You can re-use this for a long time. Most local Blasting shops can
get it for you. We use to use "old" glass bead to polish aluminium and car
rims. Also if you really want to take something down one layer at a time use
baking soda. Last point is to make sure the pressure is not very high, keep
it around 90-100 psi otherwise you just crush your media into powder and
it's no good to reuse.

There's some pretty interesting media available at your local Abrasive
Emporium. I got some stuff a while back that looked like small stars
with a hole in the center. Very dense stuff, 2 bags took two trips to
the truck, $12 total cost. Cuts like a buzzsaw. Wears out tips pretty
quick too.

Why remove all the filler? All this baloney about "gotta get down to bare
metal" I now think is pointless. If the stuff hangs on there like glue,
just PAINT OVER IT.

I learned this when I redid my Walker Turner band saw. I insisted on every
square millimeter of cast iron being clean and then I painted it. Sure, it
looked great. Now it's usually covered with chips, who cares?

I actually have about 50 lbs of aluminum oxide..but its very very very
fine stuff. Talcum powder fine. Polishes well, but only polishes the
paint.

Ill check locally..or try the heat trick this time around. Id much
rather blast than heat and strip then fiddle with the detail stuff.

i find aluminum oxide doesn't last very long when blasting glass. i get
better longevity using silicon carbide, and it's sharper too.

Simply because the edges dont feather very well. They seem to crumble
leaving ledges rather than a smooth blend.

I was going for "One nice looking machine in the shop" on this one.
Shrug..Ill likely give up shortly and simply spray it as is.

Just contact a local Sandblaster and see what they have. There are
hundreds of different media for different applications. As far as aluminium
oxide goes this also comes in different grits so get something a little more
course.

My opion on stripping the machine is do it right, I have a few "OLD"
machines, welders etc. that I stripped, replaced older wires and had powder
coated. I've had more than a few people want to buy them from me for their
shops. Honestly for some of us I take as much pride in my work as I do in a
clean shop. After each project I cleanup and then start the next one. A
clean shop is a happy shop. Also I find that people that borrow my shop
respect my tools more when I take care of them.

Use coal slag, Black Beauty, Black Magnum, etc.. Should cost between 8 and
12 dollars per 40 pound bag depending on quantity. I blasted a very corroded
dump body last summer down to white metal. It stings a little bit when it
bounces back on you, so wear a suit and use a shield for your face.

I understand - but my restored 1930 Delta drill press that I painted in 'cover the Earth"
Machine Green has held up nicely over 40 years. The original coat was failing and the
machine would have likely rusted to death in the salt leaden air of the old house we lived
in.

As an alternative to coal slag and a big compressor/sandblaster, you might
try a needle scaler. It should chip the filler out pretty well.
