What's a good source for abrasive grit?

That famous auction site...search for tumbler grit. I got a little bag of 400 grit that has lasted me for years with no end in site. My favorite is to put glue on the ends of toothpicks and stick them in the container and let them dry, but you can use any shape you want.

Thanks for the reply, Doug. I looked at what they had there and there are so many different grits. They list 36 as coarse, 100 as medium. What is 400 like on plastic?

I actually use the grit on homemade tools mostly for cleaning up metal gaming minis. As for plastic, it works well for small detail parts and engines and whatnot, since you can make small tools in different shapes.

I also make my own padded sanding sticks. I use what they call eva foam...comes from the craft store or the craft section at walmart in sheets...I glue down a whole sheet to the back of a sheet of sandpaper, then to the back of the foam I glue down a bunch of popsicle sticks or bits of wood...let dry and cut up. They don't last as long as the pre-made kind from the hobby shop, but they are a lot cheaper, and I can mass produce them.

Similar to the one above, Old record player needles installed in a pin vise makes a great scribe / punch. They are made of a pretty hard metal and will last a long time.

There is a company that make sandpaper on a roll that is about 1.5 in wide, design to stick on aluminum sanding blocks. I cut a piece about 4 in long of each grit and stick to my bench mat along one side.

Hugh! I have been trying to figure out a method for centering holes in rod and hex rod for a long time. I literally lay awake picturing a tool like a dual head pin vice. And here you come with a stunningly simple solution. I will have to give this a try. Now if I can get my Chop It to cut an even slice I can make easy nuts!

Thanks!

Not really home made but since sand paper came up, here's something that makes my life much easier. Above is my sand paper cabinet. It cost something like $7 at Walmart

I wanted to have two different grits per drawer, so I made some simple drawer dividers from cardboard

Then I took standard size full sheets of sandpaper in the grits I wanted. I inherited my father's garage full of stuff so I had most of it in stock!

I cut these handy little sanding sheets on my roller cutting board. Size is an inch square. You get a ton of them from a pack of sandpaper. More than a year's supply of most grits.

Insert squares in the bins and you are set for a very long time. It also saves on sandpaper since most guys waste a lot tearing pieces off the full sheet. I use these for most of my hand sanding.

The wooden stand underneath the "Mad Max" box top picture I made for supporting my cars as they glue. I nailed three small blocks of wood to a flat square piece, then nailed a magnetic sign (like the ones you see affixed to business cars every day) on the top with the magnet side facing up. I then have two/three steel elbow brackets that stick to the base so that I can move them around to hold car parts in place like wheels to an axle, door panels, etc... It really helps with keeping wheels level and straight if you have axle components that are glued and drying so that they don't knock themselves out of position (and so you don't have to sit there and hold parts together for hours while waiting for the glue to set...). At some point I'm going to attach aligator clips to the base so I can have new ways to hold glued parts as they dry.

Allen, I think I understand what you've built but some close up pics of the stand with a part being held would really be helpful. I'm always interested in stuff like this. I use one of these mounted to a 2x6.

I've got another gadget I use that has 4 arms, made of thick wire with alligator clip on the end. I use some as well. Can't remember where I bought it though.

This one isn't too high tech, but it does do the trick,...

BMF / crevice / burnishing tool !

I made it from a bbq skewer (bamboo) sanded one end to a soft point and the other end is rounded smooth

I wound tape into a tight tube (think hockey stick) and wrapped it around the skewer

then wrapped the wrap with masking tape

This little buddy has gotten into some tight spaces to align plug wires etc. , etc.

The tape wrap helps to smooth foil around those pesky window openings and compound curve areas

Here is the base standing on its end....

So I'm still unpacking and moving things around, and can't find my metal L-brackets, but imagine a piece of metal held in place by the magnetic base, pushed up against the car on either side, so that a newly glued wheel will set straight instead of askew.

Blank car magnetic material...

They can be bought for any strength and outdoor longevity. And if they become too gunked up from spray paints, glue droppings, etc..., remove the nails and affix a fresh strip.

Banner design shops have these, and at one point you could also find them at Office Max, Office Depot, Staples, craft stores, and even K-Mart, Walmart, and Target.

And if you use magnetic stainless steel brackets (which also exist...), it's easy to clean off as well.

LAST NOTE: the idea originated from the "other" car modelling magazine, FYI.

I can't say this was my idea. I got it from Dr. Cranky here on the forum. I'm lucky enough to have a son that's a CNC machinist so I asked him to make what I'd call alignment blocks. They're made from stainless steel, measure 2"x2"x1/2" thick and weigh about a pound each. I use them to align wheels/tires.

Someone on the forum did the same thing by taking two heads from one of those adjustable shop squares, putting them both on the same ruler. The tires clamp square between the sliding handles. Hard to describe and I don't have my camera handy.

I've seen that trick before. I think it's good to know how to do something different ways. circumstances can dictate the best one to use.

made this magnet table by laminating (2) pieces of Baltic birch (12" x 18") and a sheet of 16 ga. galvanized sheet. routed the edges with carbide bit. brackets mentioned above; magnets from big box store cabinet hardware department with holding bracket muckled off. ubiquitous cigar box holds other junk to shim & block while glue sets.

don't use it a whole lot, but it does become handy at times.
