6 inches long overall. I would suggest making the action part much deeper from a piece of heavy wall
tube, -- such as a portion of a fork staunchion, & then weld a flat handle on to it. The original would
have been a forging, tidied up with a file I should think, -- can't say that I have ever seen an original ? I
have never really used the tool in anger since 'Silastic' arrived. I just use a couple of turns of graphite
impregnated string, & screw this down snug to form a mechanical seal, then back off the bottom nut &
smear a SMALL amount of Silastic around the circlip & tighten the nut down snugly. Then repeat at the
top joint. Nuts only need to be snug. DO NOT RETIGHTEN, after the Silastic has set !!! Any small
amount of surplus Silastic will remain in the small void between tube & bush housing, & I can assure
you that there will be no leakage, & no need for the original ongoing tightening of the gland nut. ( I well
remember this in the old days !) Of course I discard the paper gaskets between bush housing &
crankcase & the top joint to the cambox , by doing the mesh adjustment by machining minute amounts
from the bush housing flange or the bush facing, a bit traumatic the first time, but much easier than it
appears ! but on the other hand, -- once done properly, the meshing stays stable forever ! The sealing
of this joint is by an 'O' ring in a groove somewhat improperly located right in the corner of the housing
flange, -- the actual sealing being by the corner of the machined ( & quite often seriously damaged)
edge of the aluminium casting, into the 'O' ring trapped in the groove, -- but it works ! Mind you, it would
be possible to set up an 'O' ring in the bush body, but there isn't much room on the bottom c/case bevel
housing for a good 'O' ring seating surface.
# 6222 grove classics lists it for 8.50 pounds
# 6224 It's worth 8.50 pounds of my time to buy one instead of attempting to make a poor substitute.
I'm sure the homemade tools are excellent, but my version may be sub par.
L # 6239 I'm seeking a recommendation for raw material to turn several small end bushes for a
couple of engines. The original material was an aluminum based material. If possible, I'd like to stay
with the aluminum material. Can someone here recommend a material or two using either SAE or some
other widely recognized material identifier?
# 6241 R.R. 56 is the recommended material - not sure what the equivalent in today's ali is.
