Off road bike securing device.

My youngest has quit motocross, but taken up trials riding again. I had been kitting out a four wheel trailer and put tie down points for ratchet straps. Perusing an American site, I came across a device to hold down the bike, using no straps. It consists of a frame fitted to the trailer floor. A square section rod is attached and goes through the footrests. You lean on the bike to compress the suspension,, stick a pin through the rod and release. Welded one up in about half an hour and installed it. My grandson complained about lying on the floor, under the trailer, fitting large washers and locking nuts onto the securing bolts. I told him to stop moaning and speak to me only when he had put the washers, nylock nuts on and had a spanner on the nuts. I then used an impact driver to secure the device to the floor. Photos are not brilliant, but it works 100%. Well pleased. My youngest merely grunted.

I know the pins in the frame aren't in the same holes either side - corrected that later. The rods have also been shortened as they were using the very last hole.

A couple of the holes in the cross piece were either off centre, or I drilled in the wrong place. I decided to take it off and weld washers over the holes for a neater job. Two M10 stainless steel bolts held it in place. The first came off in seconds, whereas the other came halfway off and stuck. These were brand new and I have no idea why one stuck. Impact gun failed to shift it -  in part because of limited access. In the end, I had to get a two foot breaker bar on the inside and my 3 foot breaker bar on the other end. Nut still didn't move but it sheared the bolt in half. Unusual, but sorted now.

If I do another it will have better access.

Stainless bolts need a bit of grease or copper slip on. Otherwise they have a tendency to gall under load. I:E using a buzz gun or adjusting legs on a machine under weight. 

Nice stand

sonicdmb - thanks for that. I mentioned it to a lad who shoots with us and he said the same. I haven't used many stainless steel bolts over the years - just bought a job lot of many, many nuts and bolts and these were among them. Harsh lesson learned.

Having now used the trailer and stand - it works as it should.
