Burrell Traction Engine, Differential - First steps

 Differential - First steps....  Another builder diff for reference.                                                                                  The first stage of cleaning up was completed, and the centre bore was opened up to 38mm, this was used to check the distances to the bevel gear bosses relative to the drawing below. Currently (photo right) the boss position has been slightly adjusted as the casting was not running completely true. The portion for the winch cable on the casting was quite close to finish size, so getting this to run true was key.  I measured a difference of about 1mm between the bosses to centre so this re-adjustment should also reduce this. The area to be removed, marked in blue dye, is the portion for the winch cable, this will enable the pins for the bevel gears to be drilled out. At this stage it is still just preliminary roughing out, as the teeth for the gear still need cutting. However, as it's on the limit of the milling machine and may have to

 Burrell Bits - Bearings, gear change and ME Show report Midlands Model engineer show (Warwick 2022). The show as usual was well attended, and after the break that was covid and the world gone mad I'm happy to report the numbers looked better than perhaps some of the traders were expecting. Maybe the cancelled years have inspired the next generation of Model Engineers. It certainly looked like there was no shortage of money changing hands for tools / material so all looking good for the future. There was a noticeable absence of certain traders, and I can only guess it's likely the rising fuel costs to move large machines had put them off attending this year.  I myself had planned for the Burrell cylinder block to be brought to the show, thus avoiding the costly postal charge for such a heavy item. This is just for looking at, and a future item to machine when the need arises, but for now it's just a nice to have item! Progress in the workshop has been slow but hopefully the
