YouTube 1412 Bandsaw Mods https://www.youtube.com/watch?v=wUXWDP5DyNo&t=21s

So I have been enjoying my Laguna 1412 bandsaw, and tinkering with a few useful modifications. The stock dust collection on the 1412 is really fairly good compared to other stock saws. It has one 4” dust port in the lower cabinet. It cleans a lot of the dust away, but there is still a good sprinkling on the outside of the saw with extended use. I have a three-pronged attack to improve dust collection.

The first part is to remove the slotted shroud from the machine. You don’t need it anymore, as we’ll be building a new shroud. This stock shroud was one of the few things I didn’t care for on the 1412, because you have to loosen two screws and slide it down in order to open the lower door.

To make the new shroud, you need a few scraps of 3/4” plywood, a 2-1/2” dust port, and 3/4” diameter magnets (Rockler).

Drill a 2-1/2” hole in the front piece of the shroud. Then create a notch above the hole to create some clearance for the lower guide knobs.

Shroud assembled with glue and brad nails, and painted black.

The left side is angled at 45 degrees to accommodate the shape of the lower cabinet door.

The right side has a curve to clear the factory dust port.

The side pieces were notched before assembly to clear the lower guide assembly. Sketchup drawings will be added with all the dimensions.

To install the new shroud, open the lower cabinet door, and slide it over the frame of the saw. Two 3/4” diameter magnets hold it firmly in place.

Dust shroud installed. Here you see why it was necessary to trim the left side at an angle.

The right side of the shroud sits on the factory dust outlet.

I added a “Y” fitting and a blast gate to supply suction to the new shroud.

Instead of drilling into the metal cabinet, I made a mounting block from 3/4” plywood and four magnets.

Screw the stable gate to the mounting block, and stick it to the side of the cabinet. The Rockler magnets are really quite strong. This arrangement holds the 2-1/2” gate in the perfect spot for easy access, yet it’s not in the way. Plus it leaves a nice spot to store my miter gauge. The 2-1/2” gate stays full open all the time during routine sawing.

I have one 4” metal blast gate that I use to operate the bandsaw. The 2-1/2” gate is between the metal gate and the saw.

From the front, the bandsaw hardly looks any different than the stock configuration.

Now onto the second phase of the mod. Block off part of the factory dust port. Do this with a piece of 3/4” plywood with 4 rare earth magnets epoxied and inset in the plywood. The plywood insert is 5-1/2” wide and 6” tall, and you’ll need to trim one corner at a 45 degree angle until it fits. Installation is simple, just snap it in place. This concentrates all of the suction right at the blade.

The third and final phase is to install a firm piece of foam under the table. It installs between the table and the trunion assembly. Mine is a “kneeler pad” from Harbor Freight. Angle it per the Sketchup dimensions, until it fits under the table. The goal is to have the front edge of the foam meet the new shroud you made. Also, the cast iron table should pinch the foam slightly as you lower it to the 90 degree stop.

The kneeler has a convenient handle in it. Here it has been trimmed to fit the space. Use the bandsaw to cut the foam (of course).

Drill a couple partial-depth holes to clear the four bolt holes under the table.

Another shot of the top of the foam insert, ready to be placed under the table.

So How Does it Work?

As mentioned, the factory dust collection does a pretty good job of clearing dust. However with this setup, there is actual suction above the table, and around the lower ceramic guides. My wife was watching me cut slender wedges for a rocking chair project. Every one I cut went SHHLLEERRPP…. Blip…. gone. Sucked into the dust collector. She thought that was so hilarious. “It’s gone” she’d say… “Make another one.”

Like all systems I’ve seen, it will leave a sprinkling of dust as the blade enters the cut. Once you’re cutting though, collection is perhaps 90-95%. I certainly couldn’t ask for anything better.

All mods come with limitations, and the limitation here is you have to remove the shroud and foam pad to make angled cuts. It takes about three seconds to pull the magnetic shroud off, and remove the foam pad. No tools, no knobs. I almost always use the bandsaw for square cuts, but if you do angle the table… shut off the 2-1/2” blast gate. This way the 4” dust port will continue to offer some dust collection for angled cuts.

For blade changes, just pull off the magnetic shroud.

Now that I know how to improve the dust collection all I need to do is scrape up the funds to buy the bandsaw. It is next up on my wish list.

Yeah, it’s a nice saw. The DC mods are very easy to make.

Take care

Nice mod. I have that saw and the dust collection is my only complaint with it. At the beginning you stated that you used 3/4” scraps. In the first three SketchUp illustrations what are the thickness dimensions? Did you double up the plywood, or remove some of it? Thanks for the idea!

Everything is 3/4” plywood. I used the bandsaw to cut away some of the left and right sides. If you remove about 3/8” thickness, for the upper 2-3/4” it will give you good clearance away from the lower guides.

To anyone doing this DC mod at home… The foam insert is cut to 13” x 5”
It needs to taper from 1” thick at the back, down to 11/16” at the front.
Again, I used a kneeler pad from Harbor Freight to make the foam insert.

Cheers

I just built this for my Laguna 1412. WOW! This works. I resawed a 6” x 36” piece of hard maple. There was zero dust in the lower wheel, NONE on the outside of the saw, and only a small amount on the top. I am impressed. This is a huge improvement over the standard dust port. I just have it connected to a Rikon 1.75HP dust collector thru about 6 ft of flex hose, so nothing special there.

Thanks for sharing your design!

Thanks for the feedback Aaron. Glad to hear it works well for you. That’s encouraging to hear it’s effective with a standard size dust collector. I was amazed myself how efficient the collection is.
