I have a 1992 LT40 hydraulic. The sawdust just exits out right behind the bandwheel which, of course, means a lot of it is in the air as you walk down with the head while cutting. The newer LT 40 that the fellow who used to cut for me had, used a detachable spout or chute to deflect the dust nearer the ground. Has anyone made their own chute? I have some ideas but thought I'd ask here first.

I think there might be many options here, and I wondered how you guys deal with the dust as you are walking through it, I know how much it builds up, and I do like to walk on it better than a concrete foor, but sooner or later something has to be done with it, not to mention the dust in the air, wmz has the tubes that fasten on shooting it lower to the ground, but you could make one as well. maybe come down a bit then  angle the tube straight out a few feet beyond the path you a walking, something rigid like pvc pipe or a thin wall flexible steel tubing maybe.  david

Some I believe hang a 5 gal bucket to catch the dust.

I would also like to see some pics of a modified older saw. Mine just throws sawdust out the big hole in the bottom all over the batterys, tire, its especially bad when the winds blowing.

If a bandmill is fed too slow it tends to make finer dust and more of it ends up airborn.Look at a newer mill and see what has been changed.Has anyone tried an old cutoff blue jeans pantleg on the chute to aim the dust down.?? My homebuilt just kinda spreads it out behind the mill on a cement floor where a snow pusher is used to pile it.Never noticed much of it airborn unless I was recutting dry boards or feeding real slow.

Not yet, but I sure will the next time I saw 8) My biggest thing with the dust is that I have chronic sinus problems and also wear glasses. Neither of which is helped by a lot of dust in the air. If I wear a mask, my glasses fog up. So, anything to keep my head out of the dust stream will help. The newer mill I worked around wasn't near as bad since it had the extension and put the dust about a foot off the ground instead of at eye level.

I keep a rope on my chute. This lets me adjust where the chute throws the sawdust. I can put the chute all the way up if the wind is at my back. If the wind is in my face then I can lower the chute but keep it just a bit higher than normal and it will put the sawdust just a bit further out.

You can just see my chute with the rope in the top left of this pic.

I believe that is Okrafarmer's little boy playing in sycamore sawdust.  It was only about 100° that day  :-\.

Hello,
I have seen a leg from a pair of blue jeans as a saw dust chute. I worked well. Not sure if it would work for you.

yellowrose, If you have a spout and are trying to extend it a 2' piece of 4" ads drain pipe ( black corrugated plastic) might work. My first mill was an '86 lt30, the dustexited straight down thruogh expanded metal underneath the bandwheel. On that mill I cut a hole in the guard and bolted on a chute made for a newer woodmizer. Judging from the map on your profile we're only a couple of miles apart, we shuold get together sometime. Jim

I suspect that you are just wearing the wrong mask.  I always wear safety glasses and a mask.  The mask has an exhalation valve which lets the warm moist air escape.  Here is the one that I use:  Dust Mask

I'm sure you can order and install the metal sawdust chute to your mill. I don't think mine came with it but it may have.

After about a week of shoveling up the sawdust at the end of the day, when we first started back in 94, we decided to add a bucket:



 

When I was sawing dry beams into flooring we had a very bad "air borne" dust problem. I duct taped a cotton towel around the elbow to at as a fine sawdust filter.
When the towel wasn't puffy any more the bucket was full and we'd dump it.

Worked for me.

Good luck.

Please some pics of anyones chute on an old machine with the expanded metal opening.

I don't have any pics but the chute was the same as the piece Jim Rogers attached the pvc fitting to. It's hinged at the top, I just bolted the hinge to the shroud so that the bottom horizontal piece of the chute contacted the lower edge of the shroud. Then I cut a square hole in the verticle part of the shroud about 3/4" up from the bottom. I think I had to fabricate some sheet metal to cover the triangular holes on the sides of the new chute. I left the expanded metal open in case the chute clogged. I think the peice I bought was used on pre-'97 lt40 mills. Hope this helps. Jim

This is what my sawdust chute is!





It's adjustable, using the turnbuckle or if I want to really throw the sawdust (depending on the wind) I can just raise it all the way up and out of the way.

One of the previous owner had removed the piece of metal that directs the sawdust towards the ground, I just added the adjustability!

, we shuold get together sometime. Jim

We have, many times, just not lately. The map isn't exactly right. I live across from a certain chainsaw carver and if that isn't enough, I've got a dandy IH R200 dump truck that you so generously donated to my cause years ago. You should stop by sometime and drive it around. I use it quite a bit for moving dirt and firewood on the farm. Thanks again! It's your mill I was referencing in my original post. Mine has no provision for a chute but with some of the ideas I've seen here, it will soon.

Jim H

Good to hear from you. The map threw me off a bit, I sawed some logs across the road from you back in the summer.

From another thread I found the part# from woodmizer for the chute extension kit. Woodmizer part number for the sawdust extension kit A12297. It was about 75$ including shipping and I got it today. It consists of the metal adapter to go over the piece where the "fingers" are that turns into a round shape and the rubber extension hose. I had to shorten up the "fingers" to be able to flip it up like it's designed to but it fit great. I love to fabricate stuff but for the money I couldn't have come close to the woodmizer piece. Thanks to the poster in the other thread for bringing the part number to my attention.

Finally got a chance to take a picture of the kit. Obviously, it's the shiny new orange piece.

Looks good yellowrosefarm.

Well worth the $50-60.00.

Keep in mind though, that unless you modify the exit itself, you still cant throw the sawdust out all that far when using the extension!

Why is that?

I know I made a post about this but, heres mine after a little cutting, welding and bolting the chute kit on.

In this pic, just above the reflector on the sawdust exit there is a piece of metal, the width of the exit that direct the sawdust downward.

That piece has been removed from my mill, while leaving the angled pieces on each side of the exit.  Now I can point my sawdust chute extension straight out and send the sawdust a lot further out!

I see. Mainly, I was looking for a way to keep the dust out of my face and out of the path where I walk next to the mill for a day's worth of sawing. I think this will do the trick. Plus, if I ever do build a shed to saw under, I'll have a nice round connection point for a sawdust blower.
