Friends:

Here's a tiny part of the next release from Compass Rose Toolworks.

It's a little selfish, but I love showing a snippet of an upcoming tool and reading the guesses. I'm always blown away by your analysis and creativity. I didn't think anyone could possibly guess the Vise Block (especially since we invented it) but two of you got it right on the money.

Amazing.

Honestly, your guesses also spark ideas for other things we might make. So, here's a tiny shot of our next tool. What do you think it is? (This one's probably not too hard, but we'll see.)

Oh, and we're hard at work developing the injection-molded vise block. Naively, I thought we were going to send the CAD file to the molding shop and they'd split out a run of vise blocks (after we paid for the mold to be machined).

How wrong I was! Injection molding is SO complicated and requires the walls of the product to be quite thin to prevent warping. Our little product needs a complete redesign before it can be produced. There's an engineer involved. Crazy.

Many folks have requested a left-handed vise block and we're looking hard at that possibility. We very much want to have a leftie version, but cost is a factor.

We'll keep you posted.

See you tomorrow.

Plug cutter?

Benjamin Fouty

It’s a paddlin’ paddle fpr initiating new woodworkers. On the vise block, what is the current material, specifically? Have you considered press molded polypropylene or a laser cut wooden block? Press molding has much cheaper tooling and can be thicker. Not sure if they’d do something so small. Laser cut plywood blocks can be done at box tool makers and are about an inch thick.

Rex Krueger

Trying to make the vise block with any subtractive process is a loser. Too much material lost or too much cost in assembling the pieces. Good ideas, though!

John Kamenik

That was my immediate thought as well. Best guess is those are pins to register a replaceable fence. However, most shooting boards are also bench hooks, and I don't see that part.

Koen de Boeve

bolt heads, so removable? overhang, but for what?is it an adjustable stop block?

Koen de Boeve

perhaps that dowel (or at least I think that it is a dowel ) is a pivot point, maybe a mitre jig?

Rex Krueger

It is a dowel, but it is not a miter jig. (Now that you mention it, though, that's an interesting idea...)

Koen de Boeve

is it some sort of a vise or clamp to align something?

Joe Meyer

Pre set hole compass 90, 25,45.

DeQster

What about sending it to a 3D print farm at quantity? Cast molding these might be at a loss, but with sufficient quantity you might be able to afford it sent to an outfit like Shapeways or similar (but cheaper). Carbon fiber filled nylon would be tough as heck. Also, the left version would certainly be better done this way as long as you could guarantee durability equal to that of the right hand. Left hand molds are NOT cheap, and often those parts are made at a loss. I used to work in compound bows, those were not really profitable. 😁

One visible peg glued into the top board, two visible pegs with space those are glued into the bottom board. So the top is a moveable part. ..... Shooting board or table saw jig?

Rex Krueger

A very detailed analysis, but all the pegs are glued in place. It is not a shooting board, but I expected that guess to be more popular. It is not for the table saw. (I admit, I generally think table saws are unreasonably dangerous if you can't get a SawStop. I kind of want to nudge people away from them.)

Thomas Hverring

Compass Rose Plywood—plywood with a logo! Get some plywood, get Compass Rose Plywood! And get it before your neighbor! Folds down for easy storage. (For some reason the Gator Grip ads from the nineties are just stuck in my head. "Get a grip, get Gator Grip!")

Mike Smith

Erm... dowel making jig?

Preston Shick

Darn. Was hoping the dark rings on the right pegs meant movable lol. Back to the drawing board.

Stuart

I am going with a CR branded bookcase to store all his videos :) Or maybe it is a bench hook / shooting board. I notice hooks getting cameo appearances more and more recently.

Richard C von Brecht

A space based laser cutter was my first guess but the power supply isn’t large enough. My second guess it’s some sort of alignment jig. That’s vague but the power supply is the right size.

Clint

A drill guide to help make straight holes with a bit brace?

DALE PATTON

Compass Rose Termite Trap?

Russell Gough

You’ve already said it’s not one, but I was truly hoping for a shooting board. lol

Rex Krueger

We are also hoping for a shooting board, but finding a reliable CNC shop that does big orders at a good price is harder than you think. Much harder.

Mike Smith

I'd definitely buy one, I never have the correct size dowels when I need them. I'd make my own, but that won't help Compass Rose grow... and I do like a cheeky tool purchase.

GFHWoodWerks (Gregory)

Injection molded parts aren't all that complicated to design. Just make sure you keep wall stock uniform, define a parting line, incorporate appropriate draft angles, design for mold flow,.... oh if there are actions required in the part you need to allow for transitioning of most of those as well. Yeah I'm being somewhat a smart arse. It is critical that you try to optimize a design so that the tooling is a simple as possible, so the processing is as easy as possible and that you still get the strength you need in your part, while using the least material possible.

Michael Bennett

Wouldn't it be cheaper and easier to produce the parts for a shooting board on a table saw? It seems like CNCs are all the rage right now and it seems that makers are finding any reason to use one. I think it is because they're still trying to justify the cost to themselves. I look at it like how you can often cut something faster with a hand saw than it takes to set up a table saw. You can cut things faster on a table saw than it takes to program a CNC.
