OutdoorKing Repair Forum Forums Restoring, Customising and Modifying Reel-Type Mowers Morrison olympic 600 backlap tips

Hi everyone,

First post so not sure how it all works just yet but see how this goes.

Ive got an old morrison olympic 600 that i would prefer to backlap rather than send off to be sharpened. Unfortunately none of the sprockets have nuts to backlap the conventional way with a drill (as backyarders like me do it. Ive also got a SB 65). The only alternative I can think of is to make an adaptor to screw on to the reel where the sprocket sits. Curious to know what others have done in this situation. If an adaptor is the play, Im interested if anyone knows the thread off the top of their head, so I can get a reverse thread nut to suit.

TIA, Dom.

Hi Domenic,

You could try typing back laping in the search bar at the top of the forum and you will see a lot of topics regarding the issue rather than try to look through the forums.

What we used in the past (many years ago) was use a retangle block of steel and drill holes in it and place a bolt in the centre with nut either side to lock it and then drill two other holes so that a bolt will fit into each side of the sprocket. Not hard to make no welding etc.

Hope that this is of some help to you.
