oprod,
Here is page 3 and 4 of nine scanned pages of an "E" head manual I found in the archives. Although I only found 9 JPG pages (plus 1 readme) in the archives, there is a reference to page 18 about the cutting tools, in the "E" head description. JPG file, page 3 is page 18, and the tools are shown on this page. If you can't find these JPG files, send me a PM and I will email them to you.
As Greg mentioned, Page 4 indicates, 1/2 pint of Mobile 600 W oil is used in the wormgear area.
Not to hijack this thread, but you may also want to know this too. I have a question for Greg, since he seems quite knowledgeable with this unit. When I was cutting a square hole in a piece of 1/4 inch plate steel, using a carbide tipped tool similar to a cutoff bit (about .125"(carbide)X.070X.250"X1.500") mounted in a round shaft, which was mounted vertically in the clapper box. The bit would skip off the cut and form a rounded edge and the side of the wall was therefore not vertical. The cause was obvious in that the clapper was pivoting under load and was not fully returning to the rest position. I could hold it forward (towards me) with my fingers and it would cut OK. I disassembled the clapper and checked for wear and/or burs on the pivoting pin, cleaned and lubricated the parts, and looked for other reasons for this apparent binding or instability. I found none. I adjusted the spring to maximum, and even bent the spring a little to increase the pressure; but ended up turning the clapper 180 degrees [so the clapper box would have to rotate towards the cut] to make my cuts. I was able to make a great looking 1 inch square hole but it worried me as to why this was happening. I could of course be totally wrong about the proper setup of the clapper. Advice would be appreciated. Joe
