I did these mods some time ago but just realized I should share them here. The saw is a Harbor Freight "4x6" bandsaw.
One of the first things was new wheels to make it more stable. The bushings are made on a lathe.
The next was to move the outer guide bearings up a bit to reduce jamming from swarf and to help make the blade vertical. I get REALLY nice cuts out of this saw. I simply chucked the guides in the lathe and made the hex part thinner.
Then I got what was to be the first of a number of orders for custom lighting dimmers for a circus group in Canada. One part of the design needed sections of 3 inch x 6 inch aluminum tube (used to make hanging brackets). Well, I have a 4x6 saw, what could go wrong?
Some settling must have occurred during shipping a the guide bearings hit the tube. Insert bad words here.
The bearing guide was all the way back and the tube was all the way against the right hand stop.
So, grab some scrap... err ... not currently used steel angle with a nice rust... err ... aged finish and make a new right hand stop. While at it, bring it right up to the blade for cutting smaller items.
Presto, I can now cut things larger than 6 inches!
Here's the lighting dimmer with those aluminum bits on, they hang under the seating on the X supports (like scaffolding). The dimmer provides 40 Amps @ 24VDC for LED lighting.
Hi, new to this forum.
I bought one of those used last year and welded my own base for it. OK, how do you keep the blade cutting straight? I tried a few adjustments but nothing seemed to help. Tried tightening it all the way like some guys on YT suggest, still it drifts to the right using it horizontal or upright. Thanks.
Assuming it tracks ok, then check the blade for tilt, you may have to tweak the guide bearings a little or a lot. See my bearing mod that might help.
Make sure your tension is good, you should get a nice boing sound from plucking the blade.
Already thinking about doing the same as you. I have had my little saw for 30 years and it does have sentimental value as my late Mother bought it for me. But the thin base unfortunately lets it down. So after seeing your post I feel after all this time the saw could do with the base upgrade. Thank you for posting I will let you know how I get on making it.

Thanks, I'll try that adjustment. I played with it a few times, tightened it all the way, adjusted the blade square, and it still drifted to the right. The Harbor Junk manual that came with it is about as clear as mud on adjustments.
I worked at a place where we had a real h-saw (an expensive Jet unit). I must have changed that blade once a month and never, ever did an adjustment on it. We did thousands of cuts and they were always as straight as can be. Sigh.
My base upright, it's very solid:
