First off I promise to get some pictures posted this weekend and start a refirb/resto thread with my before and after pics.
So I am redoing a 1954 Mark 5 and want to determine the age of the 4"
Joiner and Magna Bandsaw, any help would be great.
Second, I am disassembling the Mark 5 and stripping the paint (which is black painted over the original green. After removing the way tube tie and power head. I want to remove the way tubes to polish them up as best as I can. One way tube was loose already and with a little wiggle came right out. The second one seems to be held in by it's set screw. Looking at the set screw it seems that the only way I will be able to reach it is if I remove the pivot pin. Which seems to be held in place by a roll pin. With a long Allen key I may be able to access the set screw but regardless I would like to fully disassemble to paint and resto. So how do I get this roll pin out. It seems like the only way to go is to drive it in deeper. Thanks

With a long allen wrench you can get to the set screw without removing the pivot pin. It is not easy but it can be done. Make certain that you get the allen wrench properly inserted into the allen screw. You really do not want to strip out the socket in that setscrew.
Removing the pivot pin is not necessarily a piece of cake operation. The drift pin can be hard to extract. If you chose to do that, I strongly recommend that you use a properly sized pin punch. Using a make shift tool can introduce a problem here too.

I have had good success with a 5/32" pin punch for removing the pin in the base arm. My 1/8" pin punch gets a pretty good workout on other roll pins found on the Mark V.

I haven't had any luck reaching the set screw without removing the base arm pin. It just takes a pin punch (or flat ground nail) to knock the roll pin out to remove the base arm pin. This image shows the location of the pin in the upper right corner. However, JPG's photo also shows that the set screw CAN be reached with a 5/32" allen wrench.
Thanks again

Thanks again for all the great info. I guess I didn't look closely enough the first time around to see a hole for the roll pin to come out. I have a set of steel and a set of brass drift pins so I will definitely employ them in removing the pin. It just didn't appear that there was a place for the pin to go. I will take a closer look after work tonight. Thanks

I'm sure that it does not need to be said but if you are going to pull the pivot pin - remove every thing from the way tubes before you attempt to do that.

Better yet, remove the way tubes!;)

If he could remove both way tubes, we would not be having this discussing. He cannot get the set screw out. OR I am the one who does not read the posts.

Good point! I did not think that through!:o
However the pin has nothing to do with removing the set screw. The hinge pin need not be removed. It is just
easier if it is out of the way.
