machine to hog out beams
« on: December 03, 2007, 06:57:21 pm »
has anyone ever made a tool to make a beam into a 'U' shape. pretty often i have people request that i make a 8 or 10" deep 6" wide notch in a beam. it is so that the beam can then be put in place covering a stuctural piece of steel, or glue lam etc... right now i just use a chainsaw by hand, which is slow and not that precise.

The solution that I usually see to that problem is to take three boards and 45° the edges so they can be nailed together into a beam shape. If done accurately, it comes out fairly nice. I would think to hollow out a beam into a U shape would take one heck of a tool to do it in one pass. Perhaps you could use a large circular saw and make a bunch of passes, and then knock out whats left with a mallet and smooth  the bottom with an adze?

This last summer we visited the Blue Ox mill in Eureka, Ca. 

They made redwood gutter out of solid redwood using a very large molding machine.

A swing mill can handle that task just fine.  A built up beam as mentioned is certainly more practicle.

Practical yes, but if the client is picky and has money dripping out of his pockets we will do the impractical.

i slab plenty of beams to make "beam wraps". but that is not the question here. a swing mill can handle that easily, ... exactly how is it easy. i have never used a swing mill, but my guess is you are talking about many many passes which would take lots of time. also how deep can the cuts be? the spec on the beams today was a 9" deep trough.

I've hollowed out several logs to wrap around structural members in "rustic" decors. I always did it with a chainsaw as well and I too figure there must be a better way. I've wondered whether a log wizard would work. I had one once for stripping bark and thought it was worthless so I got rid of it. Sure would like it back to try hollowing with though.

That is interesting Dale. I was sitting here trying to think how a Log Wizard could be used to do that, but they were one step ahead. :D I betcha there is still a lot of time involved to use that, there is a lot of material to be removed in lots of thin shavings.

what about a hand held planer?  those things can hog wood pretty quickly.  put up a fence and have at it, or a chalk line or something....  easier than one on a chainsaw...

You just need a 6" wide dato for a swingmill!  :o :D

Seriously, though... you could do it with an 8" or 10" swingmill, depends on how deep it needs to be... make a bunch of verticle cuts and then hog it out with an adze... for that matter, you could rent one of those Makita beam circular saws, use a fence, and do the same sort of thing, albeit slower...

Yea then mount it on the axle of your Dodge Cummings Diesel Truck and do a Burn out down the log.  It'd be a great event at the county fair.  :)

I do these alot on my Lucas. 8 1/2" is the max depth, but it is fairly easy to hog out more with a chainsaw, especially after you already have a straight edge to follow.  I have also hogged out the back of a full log to wrap over an existing beam or door ways.   8)

I contemplated patenting a process like this but it wasn't worth the investment given the market (demand). I invested many thousands and have a workable prototype and will have it online for use in a few years (not the priority it once was). Slab and miter, much easier!!

There was a thread on here a couple of years ago about a log lathe. HERE is a link to something similar.
(click on the log beaver if the link doesnt open to the right frame)

I dont see why you couldnt mount a router bit or some sort of milling head onto the engine shaft and achieve what you are trying to do using something similar to this. Just set the height and push away!

Checked on that "Log Beaver" mentioned above and found this: "Jober Blc is proud to show you his new product : the Beaver. This de-barker can turn logs down to any desired diameter. It can handle a log of up to 14 feet in diameter and 13 feet long."  WOW!  14' in diameter!  I'd love to see that hummer in operation- that's a log wider than it is long but can you imagine the bowls you could turn?  Actually, they'd be bathtubs!

That's a typo, it should read 14 INCHES in diameter. I feel pretty confident that the carraige of that machine wouldn't hold a 14 foot diameter log! :D

Yeah, you're probably right but it sure fires up the imagination- only think is, finding 14' diameter logs here in the deep South ain't happening in this day and age, so it's a pretty useless fire and all...
