Background:  I got an Ellis 1600 bandsaw to replace my 4x6 hori/vert bandsaw.  Everybody's got a 4x6, right?  Since the Ellis got here, the 4x6 just kind of sat around and collect dust.  The only reason I kept it around so I could set it up to cut different angle without having to set and reset the Ellis.  But then I saw this thread by Montgoc3 where made his 4x6 into a permanent vertical bandsaw.  Now, I've used my 4x6 in the vertical mode lots of times, but wasn't happy with the throat depth, so I never got around to make the same modification that Montgoc3 did... until I figured out how to double the throat width.The gist of it is this.  In order to function both as a vertical and a horizontal bandsaw, the designers of the 4x6 twisted the blade 45 degrees.  This is achieved by a "twist" in the bearing cluster holder (pics to follow)... So, once i got rid of the twist (by making a new bearing cluster holder), the blade will always run flat, without twist.  Best part --- by untwisting the blade, you doubled the perpendicular distance between the blade and the body of the saw... anyway, here's a bunch of pictures to show you what i mean.--------------------------------Here's the before picture.  You can see the blade coming out from the bottom of the picture, it's twisted by the two roller bearings in the bearing cluster, then goes on up where it is held by another bearing cluster (not in the pic).--------------------------------Here's a shot of the stock bearing cluster--------------------------------If you ever taken your 4x6 apart or adjusted it, here a shot of the stock cluster holders and the ones I made to replace them (please excuse the clutter on the welding table).  The two on the right are the stock ones, I thought about cutting and welding them but I might want to be able to use it as a horizontal one day.  Besides, I'm not Castweld, and this is part is made of cheap cast iron, so I figure I best leave cast welding to the experts, and make my own. -----------------------------here it is installed into the saw-----------------------------both top and bottom--------------------------------here's the platen, made out of some scrap 3/16.  Top one is the one that came with the saw.  another compromise due to the saw being used both as a vertical and horizontal saw.-----------------------------plate installed----------------------------here's the result:here's the before again, just for reference:---------------------------As you can see, before was ~2.75 and the after is ~5.75.  Time well spent.  This is not ever going to replace the need for a "real" vertical  $5000 Do-All bandsaw that weights a ton, but it will buy lots of time for me before I REALLY need a real vertical bandsaw.

Reply:Ok here is what you need to do next.MAKE ME ONE! I want it!I've been looking on CL for about a year for a nice vertical metal bandsaw and can't find one for less than $1500 and doesn't weigh 500+ pounds. This would be great for a cheap harbor freight bandsaw!Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer
Reply:send me a PM, we'll talk.
Reply:Good work!  I may do this as well.  Using the 4x6 as a dedicated vertical has worked surprisingly well.  Need to order a 1/4" or 3/8" blade for it to allow for sharper turns!Craig MontgomeryM&L Fabrication, LLChttps://www.facebook.com/pages/ML-Fa...8228829?ref=hl

Reply:I have thought of converting my saw to vert only too, but hadn't really thought of "untwisting" the blade. Nice job there. Now this is another thing on my list.PeterEquipment:2  old paws2  eyes (that don't look so good)1  bad back
Reply:you get almost a 6 inch throat... but save thousands on a real vertical bandsaw, this will be enough to get me by for years... probably.

Reply:Wow...I love it. I happen to have a spare Jet I got free from my company when they upgraded to a wet saw. Rather than let it sit in my shed for 10 years as a parts machine...me thinks I'm gonna build me a similar rig. Thanks for the sweet design. I just love making homemade tools...and have dozens. This one will be especially fun.  I generally like 24 tooth blades on my dry cut saw...cause they last forever...even though they're as slow as sh!t sliding down a sandpaper railing.
