After the steam chests we moved on to the cross head guides. Blackgates don't have a casting for the spindle guide so we machined them from a piece of 2 square bar, although they still need finishing.
I started one of these years ago (project number 1), still fancy completing it. lovely looking tractor. Keep up the good work and keep those photos coming.
I might even slip a few ransom bits into my work schedule
Thank you for the kind words. It's both me and my father working on it so progress is a little quicker, this is about 6 weeks of work off and on. This is today's progress. The eccentrics were machined to a close fit, just a little tight as they turned, and then lapped as a set. Afterwards we swaped bits from different sets to see how close they were and they all worked together.
We're glad people are interested as it seems to be a model that isn't common. It has been more work on the drawing side as there are some parts of the drawings we've just had to pick apart and redesign it from scratch, like the water pump arrangement, or just updating it like with the metric gears. We build these kind of things below and with what has happened over the past year we needed to look at trying something new, so after building and selling some Stuart engines we scaled up.
Bought my last lot of 4 inch from Joe at maccmodels . I see he has it in stock
Has always been helpful and will cut to non listed lengths

Didn't think to ask one of the model suppliers. The fire tube material is coming from them so we should have asked about tube, although the only stuff I can see on there is 1/2" thick.
