I just got a call on SKYPE from a plywood manufacturer in Germany that wants clear round cants fron 12 to 30 inches. He wants them turned to be sapwood and bark free. In other words perfect cants that he can make veneer from with no waste.
Does anyone have any ingenious ideas as how to do this without cooking the logs and using a huge veneer machine to get them round.?

How would you keep them from checking during shipment?

How perfectly round?

I'm assuming it's to avoid shipping most of the waste 1/2 way around the world?

Would something like a "lathemizer" do the job? Hold the log by the ends and rotates it. Take 10 or 12 faces off and get an almost round log?

could you build a giant version of a wooden peg former with thick steel plates and hydraulics? force the log through the die, and form to fit? probably have to do some slabbing first, and run through the forming die to get final shape? That is a stumper

What lengths of rounds are they looking for 60" or longer?

just tell the guy you will make his plywood for him...

A rosser head debarker might do the trick for least cost. Just keep "debarking" until the sapwood is gone.

But the contacter sounds like he might not have an idea of degrade during the shipping phase. Can you get it to them in less than 6 months?

I'd suggest calling them veneer bolts and not "cants" for a bit more clarity.

They do not have to be perfectly smooth but without bark or sap wood and yes the reason is to not ship scrap to the other side of the world.

What is a lathemizer and where do I find one ?? I could not find anything on the internet.

He does understand degrade and is now buying from Africa, The ends will be sealed and strechwrapped.

He needs 8 foot 6 inch long. I just found a little info on the lathemizer. It doesnt say much, any one know about them. There are several abandonded woodmizers here if it fits on a woodmizer.

I am just happy to call them something, mixing German, English and Spanish gets a need for coffee early.

Makes sure it's strong enough.

Lathemizer can turn round posts, I saw them doing that at a demo.

Red Pill · « **Reply #9 on:** February 02, 2012, 05:40:59 pm »

Can you get to the Woodmizer website? There's info on the Lathemizer there. And, yes, it's a Woodmizer product.

Use the Rosser head debarker. It will be the fastest thing you could use. I saw one guy make mulch from logs by using a debarker. When he was done, he had a round piece that he made into firewood.

If you are using butt logs, you'll have to trim off the butt flare in order to minimize the debarking process. You should be able to do a log in about 5 minutes, depending on the amount of sapwood. You'll need aggressive teeth to get through the harder material.

Ianab · « **Reply #12 on:** February 02, 2012, 05:56:55 pm »

Lathemizer.

Seems they can make round logs. And yes it's an attachment that bolts to the bed of a normal Woodmizer sawmill.

The debarker would be your best option , the lathemizer would not be very efecient in those hard as rock woods you have.
Why are there several Woodmizers abandoned

More money in cocaine and less laws.

jim king · « **Reply #15 on:** February 02, 2012, 06:53:53 pm »

Anyone know what is the largest dia a woodmizer attachment can produce ?? Since there are wood mizers available in town that seems like the fastest bet.

jim king · « **Reply #16 on:** February 02, 2012, 07:23:36 pm »

Iwould like to talk to anyone that has a Lathemizer or from the factory . The woodmizer people here are not to helpful.

SwampDonkey · « **Reply #17 on:** February 02, 2012, 07:42:10 pm »

Jim you might get a quicker response if you post to their Sponsor Board. The forum has gotten big enough that they may not even see a question posed if not in their board area.

Tallest cut is 35 or 36 inches on the mill from the bunks .. Now what the lathmizer takes from that I have no clue but I do know it will be smaller.

jim king · « **Reply #19 on:** February 02, 2012, 08:33:40 pm »

Can you clarify that a bit¨? Do you mean the rough sawn round log can be over 30 inches and the rounding of the log makes it a bit smaller ? If that is so it would work. Next problem is how log does it take to round a 30 " log

zopi · « **Reply #20 on:** February 02, 2012, 09:08:06 pm »

tjat lathe is not a production device...takes a bunch of work to load the log...nah..debarker, or whatever they use to peel telephone poles...peel them suckers tree length the cut to eight-six with a chainsaw...

beenthere · « **Reply #21 on:** February 02, 2012, 09:26:09 pm »

The log on the lathemizer turns above the bunk, so with isawlogs numbers, less than half of 35" or at best a 17" log. Plus logs must be chucked between the end centers (think like a lathe) heavy enough to support/hold an 8'+ log of 17". Then slabs can be removed in radial increments around the log to remove slabs of sapwood/bark. If truing up to a cylinder, the band is operated slowly down the length of a log as it slowly rotates.
Seems pretty tedious for any type of production, but not saying you shouldn't give it consideration.
However larger head and tail supports could be built too.

I'm curious, as thought you couldn't remove whole logs from your Peru forests? Has that changed? or just for some species? I recall the laborers packing out cants on their backs, but maybe you have them more mechanized now.

Gday

We have a Woodlandia LL41 log lathe that will do upto 18" finish or 20" Max log dia upto 27' long logs we can do about 30 odd 18' logs a day but that includes putting the cope into the log if you where just chucking and lathing to the dia the log will get you could do more I reckon

I think they are $19500usd ex Canada www.woodlandia.com click on Log lathes then on Roundmaster and you will see pics of our full LL-41 Roundmaster line we have here

Regards Chris

Heres one on you tube thats made from scrap for a tractor pto.

Brucer · « **Reply #24 on:** February 03, 2012, 01:14:34 am »

I helped set up the first LatheMizer to arrive at Wood_Mizer Canada West. It can only handle a 13" diameter log.

It's a very slow process. First you have to saw an octagon (using the built-in stops). Then you plug in a 110 Volt motor that spins the octagon in the opposite direction to the saw blade. The running blade is slowly lowered until it will just cut the corners off the wood, and then you run the carriage to the end. You might have to make more than one pass down the log to get it round.

On the other hand, you might be able to ship the octagons as is. You're not going to get a very big piece of wood if you have to saw the sapwood off a 13" diameter log.

Meadows Miller · « **Reply #25 on:** February 03, 2012, 04:16:33 am »

I have cut plenty of octagons im thinkin they might have a rotary lathe thats why they want rounds even with A grade peeler logs there is alot of stuff that comes off in the first fair few rotations that has to be clipped back and handled again n spliced to make larger sheets

Mooney · « **Reply #26 on:** February 03, 2012, 04:47:48 am »

I'll put your situation in front of someone more familiar with the LatheMizer today and have them get back to you, Jim. Sounds like these guys are pretty knowledgeable on it's operation and capacities!

We have a Woodlandia LL41

I like the looks of this one also. In this case we will have to float the loggs out and bring them to town as the plywood company only wants turned face veneer and when he buys in Africa he only accepts one log in ten. The benifit we have is that the loggs here are almost defect free and straight as an arrow.

Good for veneer.
