Another homemade setup I use frequently.
Pic 153...This is a foam coffee cup the brand name is "Philip Cup" The cover has a little plastic tab about 1/2" wide and perhaps 5/8" long These tabs measure 0.012" thick. There are two tabs in the foreground of the pic that have been removed from the cover.
Pic 155...These tabs being 0.012" thick (which is the air gap for just about every saw ign) and nonmagnetic make great spacers when setting up the air gap. This pic is of a two leg coil. The gap must be set at the magnets so I roll the flywheel with the magnets up, set the coil on the flywheel, pick up each leg up and insert a tab under each leg. The magnets pull the coil down onto the tabs which comform to the curve of the flywheel. Put in the bolts...tighten and your done. Rotate the flywheel, the tabs fall out..move on. I always found feeler gages heavy and hard to use in a curved magnetic situation so I came up with this while having a coffee and pondering. LOL!!!
You could use any type of plastic that measured 0.012" and get the same results but it seems I always have a dozen or more coffee cups in the trash can at the shop.
These pics are from my "49SP and 70E Build fron Scratch" thread. For anyone wanting to watch three saws built from start to finish with lots of pics it might be worth a look even if older Jonsereds are not your cup of tea. Most procedures are common to most saws.
Anyway that's some of my homemade (and very cheap or free)remedies to common problems
To put the crank back in I just heat the case in the oven for an hour or 2 at 175° and put the crank and bearings in the freezer. Then I put on some welding gloves and work fast. They just kinda slide into place and I can just use the case bolts to pull everything together.
