How to make lock plates.

[wonwinglo]

In the days when Diesel engines were in vogue one of the biggest headaches was keeping the engine in the airframe due to the vibration of a diesel,bolts would literally unwind from their bearers ! some method had to be found to firmly hold the bolts in place and at the same time allow the engine to be removed if needed.

To make a locking plate drill the bearers as normal and place two pieces of tin strip behind the bearer,drill through these as well exactly the spacing of the bolts,now remove the tin plates and drill more holes into a piece of scrap wood the same spacing as the ones drilled into the tin plates,tighten up the plain nuts onto the bolts,tin the nuts and with a very hot soldering iron fix them into place,remove the bolts from the slave bearer and tack the soldered tin plate below the engine bearers,next clamp down the engine with the bolt slots all in line,take two small pieces of wire ( a paperclip will do ) and place these into the bolt head slots,drop a bit of cyno in place and you will have a totally vibration proof mounting.

Should you need to remove the engine pop the safety wire upwards with a screw driver and unscrew the bolts.
