Ear we go......

The posts are coming thick and fast at the moment!! With the MDF brackets bolted up to the engine we lifted it back into the car so i could fabricate up the mounting ears. After some head scratching and cardboard cutting i ended up with various shapes that then needed to be cut out of steel plate. After half an hour of spark generation, 2 thin cutting discs, lots of little burns  and a melted hole in the crotch of my tracksuit bottoms i had transferred the pile of card board bits into a pile of steel. Another 30 mins in dads workshop on the grinder and sander and i had a pile of smooth brackets and lovely manicured nails. By the end of the evening the top bracket was welded up and completed, although i may add a gusset to the forward most ear.




Meanwhile Dad was busy with the front prop. After measuring, remeasuring and then rechecking dad put the front prop in the lathe to cut it down by 60mm. He then turned the weld down off original joint to remove the plined end from the 60mm off cut prop tube. After facing everything off in the lather again to ensure everything was square the prop tube and splined end was tapped back together.



Dads business requires him to weld up cylindrical joints on prop shaft viscous couplings, so basically an identical type of joint required on the prop, therefore i trust him to weld up the prop rather than send it away. You can see in the top left hand corner of the lathe photo a rather large motor and pulley, this is dads modification to the lather to allow him to rotate the chuck very slowly at a constant speed, while the mig weld gun is mounted stationary applying the weld to the joint.
