I'd had my Barranca Diamond 10 inch saw for about a year now, and ever since I got it the blade alignment has been off, visibly so. Doesn't run parallel with the movement of the vice. I believe the saw marks I'm getting on my cuts are due to this issue.
Can someone please advise on how to go about fixing the blade alignment on this saw? I'm not very handy but will do the best to try any suggestions I get. It would even be useful to know what kind of service professional might be able to fix such an issue. I don't have any lapidary clubs around me to go for help.
Any general advise would be greatly appreciated.

If we knew where you live, there may be someone nearby willing to help in person.

Any general advise would be greatly appreciated. clamp a pencil or small rod in vise and move the vise thru it travel, you will see if it is out or not. bearings on arbor should be able to provide for needed adjustment. If it is out of adjustment you will usually see large snap offs at the end of the cut. |

I don't have or know that saw.
Photos would help, in fact by taking photos of the arbor, you will probably discover where that adjustment is made.

You might check for warped blade. www.barrancadiamond.com/pdf/manuals/saw/169351_BD10_OM.pdf |

Yes, it is that saw that woodman posted in the link.
I'll see if I can figure out how to post some pictures of the arbor.
I'm in Easton, PA.

Are the slabs straight and even? I don't think there is an adjustment. To align blade with blade slot align table and then tighten down the table hold down wing nut. If the rock is secure in vise and vise locked down (the bolt you tighten after moving cross feed) and you are using a 303C or 301 blade you should not get saw marks. You can try the pencil trick and see but usually an alignment issue causes binding not saw marks. Make sure blade is dressed and leading edge flat not rounded.

I've only cut nodules with this saw. Not sure what you meant by asking if the cuts were straight and even, but I think the answer is yes.
I had some trouble posting pictures to the site, but I managed to improve the blade alignment by putting some shims between the attachment that holds the saw tray to the saw to adjust the position of the tray. It seems a pretty rough method.
Using a dial indicator I was able to improve the alignment to a point where the alignment was off by 1/10 of an inch over a 4 inch length of the blade. Prior to this it was off by 3 times that amount. I don't know of 1/10 of an inch error is still bad or is considered something tolerable, but my saw marks have improved (but still not perfect).
I am quite disappointed that Barranca Diamond would sell a new saw with such a flawed blade alignment. Being the newbie that I am, I used the saw for more than a year without realizing the problems it was causing. Because I am not a handy person, I avoided buying used equipment and opted for what I thought was a quality new saw.

I meant are the slabs even thickness or tapered? You must be cutting small nodules if using the BD10.

Most blade marks on the BD10 are from the stone riding up the blade, there is no hold down for the vise and it tends to ride up the blade if you are cutting a little too fast for the material. You might have to allow a little more slip in your feed system.
