There are some of us making tools,dont have pics but a couple of easy ones.
Made a cam bearing fitting tool,machined down a piece of aluminium to suit the bearing ID with clearance and tunnel clearance,fitted a nylon bush up the
centre of it because the ID of the bearing drift was too big, then scunged a bit of straight 3/4 bar off a mate that was 3 foot long and machined the end down to suit
the nylong bush ID and this gave me step on the bar to use a heavy duty washer with slightly less diameter than the drift itself,the washer takes force of the blows when drifting the bearing in and spreads the force out over the drift so that the drift survives and stays in shape.
Then machined another piece of aluminium to fit neatly in the tunnel with a step on it so that it didn't push through the tunnel,this piece acted as a guide and it
also had a nylon bush in the centre that was a neat fit over the bar. It worked for me.
Made a spigot bush drift,very simple,just machine a piece of 3/4 bar down at one end to suit spigot bush ID and a heavy duty washer over the machined section to
take the blows while fitting.
Made a rear extension housing bush drift,similar to cam bearing drift just a different size,had to make the bush as well because they are NLA.
This one had me stumped for a couple of days,needed to remove some ridiculously heavy valve springs but didn't want to lift the head.
Made up an adaptor from and old spark plug and air line fitting by removing the guts of the plug and brazing a piece on to accept the air line fitting.
This is used to screw in the plug hole and hooked up to compressed air to keep the valves up while removing collets etc.
Then made a tool that I could used with my left hand to compress the springs,it only has a handle about 8 inches long and it is my favourite tool ever made.
