Following on from completing the final marking out of the frames earlier in the month a start was made at drilling out and reaming through each individual hole. Prior to this the the two frame plates where carefully position one on top of the other, so that we could assured that both frame plates match each other. The above photo shows Matt machining the first hole.
The first hole being cut in our new main frames.
The moment the cutter breaks through for the first time.
At the front end of the two frame plates all the center marks have been circled in chalk pen and hole sizes marked to help show each hole position. Also in the picture the head of one of the locating pins can be seen hold the two plates true to each other.
To secure the two plates together, after drilling the initial hole, Ben is using a bridge reamer to finish a selected non critical hole to final size. Then using a precision machined pin inserted into the finished hole the two plates can be locked together.
The finished hole ream’d to size.
Progress so far at the back end with all the rear holes drilled.
Mean while inside the villa’s Sean has been busy needle gunning,degreasing and getting a coat of bonda Primer on the front and rear buffer beams.
As well as some of the many angle irons and spacer plates in preparation for assembling the new frames.
