Easy To Use
Easy install on non-delta saw
It took two people to install the fence - but it was worth it. I installed this on an old Rockwell 34-350 12" - 14" Tilting Arbor Saw which was manufactured in 1957. This fence is a world of difference from the stock fence. I did have to drill holes to mount but following the instructions and using the angle bracket as a guide I had no problems. Make sure you use a sharp bit designed to drill through metal - dont use a cheap nock off. If you dont install the fence right your cuts wont be true (duh! - but I had to say it). I should have done this years ago.

Bad choice
I have two Delta Unisaws with besiymier fences in my shop. Found a used one Craig's list so I bought it to set up as a dedicated dado machine. The saw was in fine shape but the standard Unisaw fence was a mess. So I shopped around and found a good price on the Besiymier here at CPO. Turns out that CPO is just a front for Delta and you have to deal with Delta direct for customer service.

The unit arrived in good condition with no damage. The problem is that neither box had any hardware or a manual for mounting. Since it arrived on Saturday, I had to wait until Monday to contact Delta directly. The customer service person was very nice but had no idea what to get me. After about 30 minutes and being placed on hold several times she located what she thought was the correct hardware kit. I asked for her to rush ship it. This was not an option and it finally arrived the following Saturday. Still without any assembly instructions. Worse, the bag it came in was ripped open apparently before it was put in the bag as there were no lose items in the shipping envelope.

Another phone call and 30 minutes holding got me to tech support who assured me I had the correct hardware kit. However, I had my concerns since the handle knob was not the standard ball like the others I have, but a long handle with chrome ends. The tech took my information and assured me he would send one no charge... That was 1.5 weeks ago. He did however manage to email me instructions. However, they aren't for my saw. So... 3 weeks in and I have a saw and a fence that I can't use. Oh, and by the way, I've been to the hardware store 4 times to buy bolts to try and get this thing mounted.

I'm going to give it one last try on my own. Then this thing is going back. It cost exactly half of what I paid for the saw for this fence. Seems to me that Delta has hit rock bottom and it is time to go with Powermatic.

CPO should be more clear that when you buy Delta from them you are actually buying from Delta. I have purchased a bunch of tools and supplies this year and this is my first disappointment, but wow! What a disappointment...

I have a Biesemeyer Commercial Fence installed in our table saw and it's 54"to the right and 12" to the left. Do you make custom sizes? I'm looking for 54 right and 24 to the left. If so what's the cost?
Thank you,

BEST ANSWER: just buy a longer, square tube locally and install it in place of your current front tube.
