day 19

this is a shot of the axle spacer that i machined, using the mill i machined a slot to locate the chain tensioner.

here is the tank sealant kit that i ordered from the local paint shop.  it comes with a surface cleaning solution, anti rust etch, and the tank sealant. 
put the cleaner in the tank, i think they say to mix it at a 1:1 ratio with water. after washing it around for a few min i drained the tank and rinsed with water. after rinsing i let it dry out and the repeated with the rust etch. to speed up drying i used the shop air.

pour the sealant into the tank, tape off all holes and oil any threads that you dont want coating on. rotate the tank around for about 30min. drain the rest of the sealant back into the can. let it sit for about 96hrs before using the tank again.
