   Try a cobalt bit to drill out the pin. These bits usually will bore out very hard metals, even stuff like bandsaw blades. I used to drill pieces of bandsaw blades for a walking beamsaw blades.

   The pins are used only for alignment, they don't "support" anything.  As long as you can assemble the saw and get it to line up by using the nubs of the broken off pins, you don't need to do anything. 

   Drilling out the old pins is pointless and near impossible if you don't have access to a machine shop.  If you try to drill out the pin, the drill will almost always drift into the softer metal of the casting.

   Typically the only way to safely remove a hardened steel pin from a softer metal casting is to use an EDM machine, a specialty item even in well equipped machine shops. 

   If you find that the upper assembly is shifting, bolt the parts together, line everything up, and drill and insert a couple of 1/4 inch roll pins through the front and rear flanges of the castings.

   Hope this helps, John W.

   I was installing mine on my 14" Grizzly about six weeks ago. Recall the instructions saying to get an assistant to hold the upper assembly while unbolting it.

   Like you I thought.. nah.. I can do this.. and did. But man, is that top tippy! My biggest problem was getting a wrench big enough to fit the nut.. yet small enough to fit into the well that houses the dern thing.

   As someone else has already said.. the guide pins are inconsequential to structural support. If the block fits onto the lower assembly and the upper assembly fits onto the block.. bolt it up and let 'er rip.

   Thanks for the responses. Used the little nubs to align the the riser and every thing is back together and working great. Oh yea that wrench thing, ended up having to buy two new wrenches that would fit.

   Make sure you align the wheels before you put a blade on._________________________________

   Friends,

   This is a late post but pertains to the question.

   The 14" bandsaw here actually had a problem in which the neck was pin oriented a little off disallowing any proper coplanar alignment.

   This was a few years ago. So did grind the pin off to surface, aligned the bandsaw proper just with the use of the large bolt, washer and nut that joins the bottom cast to the neck.

   When all was fine, drilled a hole at a different location, and drove a self-taping bolt which serves as pin. The bolt has a hex head so it is easy to remove.

   This bandsaw had been a hassle to align till that detail found and corrected.

   I have been trying to purchase the riser block accessory for my 14" Delta BS...without success.  Seems the item is backordered from Delta for several months.  I've looked at this item a gazillion times in the past and decided I didn't need it...now I do.  Any ideas of where to search?  I've checked the major web distributors and local dealers.

   Thanks, Fred.  I found it at Rockler, which frankly surprised me!  Others must not be aware that they carry the item cause they have more than 20 in stock...now I'll hope it shows up when promised.

   Some advice for future riser block installers.  I installed a riser block on a Jet 14" last winter by supporting the upper bandsaw assembly with rope and a pulley attached to a ceiling joist.   Made the installation safe and easy with no increase in blood pressure.
