Another way to scarify these seeds is to make a rectangular box with a 1/4" plywood bottom. The sides need only to be a couple of inches high. Glue a piece medium grit sandpaper to the bottom of the box. Then, make a rectangular platform that is one inch shorter on all sides than the box. Attach a metal handle to this platform. Place the seeds in the box and gently move the platform over the seeds. The seeds will be scarified and none of them lost. And no damage to the fingers.

Hey, thanks! Do you have a photo or a drawing of this? I've grown attached to my body parts.

Sorry. No picture or drawing, but here are the instructions: Rip a four foot piece of pine two inches wide. The sides are 12 inches long, and the top and bottom are 10 inches long. Lay them on edge and screw them together to make the box. Cut a piece of plywood 1/4" or 1/2" thick to cover the bottom. You can glue and nail it on with brads. Use a 3/4" piece of plywood and cut it to these dimensions 9" by 10". This is the platform to which you attach a metal handle. Glue a piece of medium grit to the bottom of the box. You can also glue a piece to the bottom of the platform. Place your seeds in the box and gently move the platform over the seeds. This will scarify them. Good luck. This will allow you to put your fingers to better use!

HI Equilibrium. You could send them to Prairie Moon and we can use our 'scarifier' to do it. It's a small mechanical drum lined with sandpaper - we do all our legumes in here. How much seed do you have?

"How much seed do you have?" Funny you should ask. I measured it. I had about a half a pound. Just kidding. Very little. I had enough to fit in a teaspoon.

Thanks for the offer. I put mine in a film canister that had sand paper in it and shook shook shook until I figured it was sufficiently scarified. The proof will be in the pudding if my seed germinates. If it doesn't germinate I think I would like to try making one of Porterbrook's thingamajigs but then I got to thinking... which can be deadly for me... and I went down into the basement... and found a rock tumbler the boys used to make rocks all shiny and smooth. I think this has possibilities. What do you think?

I bet it will germinate just fine! I'm attaching a picture of our seed scarifier. It does look like a rock tumbler. We can do many ounces at once. We just buy different grades of sandpaper and cut it to size. I think the sandpaper I photographed was a 60 medium-coarse.

We'll find out if you're right or wrong soon. Your seed scarifier looks like an oversized version of our kids' rock tumbler. Maybe we should dust off all rock tumblers and put them to good use.

I have successfully used the hot water treatment. E.g. Boil water, cool slightly, immerse lupin seeds for 24 hours and then plant. Sulfer acid is too caustic for me. Also, it is hard to dispose of after use.

I started some of these seeds. Mine are germinating. They came from Prairie Moon. Nice tip Darcie McKelvey.
