Finished Footrests!!

     The holiday / Hurricane week end, before any weather arrives to force me to runaway from Florida for a bit - I took the opportunity to finish the 'pegs'.
     Firstly they needed marking up for the 8mm holes for the securing pins. I had to round 2 flats so they slid into the holders correctly, then mark up the centers of the holes. This was done, then each piece mounted into my milling machine, for centering - counter sinking and drilling to 8mm:

The holes were drilled in 3 stages, counter sink, 4mm and then the final 8mm hole. I ran the mill at the correct speed for the steel insert rather than for aluminium. Seems a sensible course, avoiding excess heat from the steel and  possibility of blunting the drill bit or worse. Once both rests were drilled i re fitted them to the rear-sets, just to ensure a nice fit.
     Chem-bluing the hex part of the rests, I then marked the 45 degree slant, when machined off the angle will allow the rests to pivot up (for when I get the knee down - and no hero blobs to worry about....). The pieces were marked up and then each mounted back in the milling machine,  my cutter of choice being a 4 flute 3/4" end mill. The mounting complete i cut the angles to half the across the points depth, basically to the center of the rest. The cutter was a hot knife through butter.
    
 

Once both pieces were cut they were cleaned. Not sure if I am going to polish them as yet as I like the contrast in finish and form. The the securing pins were given a good clean and parkerized. Giving them a black to grey look. The all pieces were cleaned one final time, checked for fit and assembled.



     I am very pleased with the final finish. The pegs from Barry were nice, and I was determined to put them on my bike. That is now possible, with a little bit of thought and engineering know-how. The picture below shows the rear-sets, pegs and securing nuts. All bespoke pieces finished to within 2 thou and giving a great sense of achievement.



     Now onto the next part of the build, I do keep saying engine, but I am working up to that. I now have the tail light and the seat unit will need modifying to accommodate it. The intention is to recess the light into the unit. Beer-o'clock now.
