Thread: Farm Boy

You have some nice equipment there Derek.

Good work on the plants. I have 4 Avacado plants now growing. Got them sprouting with the seed suspended in water. Trans planted and now about 300mm high. Its great watching them grow and hopefully thrive.

Great machining work.

Thank you Peter, Kieth and Peter. Yes Peter that is why I had that old name. Spent more time in the garden digging one of the flower beds ready for the planting time. We only have a small garden 110ft long

Only had a little amount of time in the workshop but did manage to get the joint done.

With the cutter I used I needed to machine 1" from the centre line but when I offered up the front section as I was machining it slipped on at 1.0021 which I am happy with.

Screws which need to join them together will be done once the two parts are complete they are also aided with some JB Weld

Now to start machining the outsides down to size which have two protrusions on one side and one on the other.

Work on the Farm boy has been slow due to other things need doing.

I have managed to taper the rear frame with the aid of some angle blocks. I did drill and ream to final size the radius before cutting away the bulk of the metal to save time as well as reduce the amount of swarf it would have produced.

Reset the frame in the vice and machine out the gear side of the part I did not put a radius on the bottom as I did not have a bull nose bit of the correct size.

Next the other side need doing that being simpler as there is only the boss for the main crank.

Derek,

Your marking out using marking blue brings back lots of memories of old fitting and turning days. I love it !!!

I mark them out on a surface plate with a height gauge they are really only there as a sanity check I do tend to use the DRO on the machine to get where I need to as well as micrometers and the lick to double check the sizes

All of the outside machining done on the mill still need to do some drilling. Now to do the inside.

This is just a test fit and everything that should line up does. One more large piece to do and then it is all the small pieces that need making

I need to blue it up again to mark out the for the inside.

Back on the build today as I have been busy with the garden and making a replacement back plate for my collet chuck, pictured with the old thinner one.

I treated myself to a roughing end mill and used that to rough out the rear frame and I am very pleased at how quick it removed material.

Round 2 of the rear frame machined the internal to final dimension then set at an 8deg angle to machine the inner rear wall to the same angle as the outer slope.

And after the internal rear wall machined next job to cut a circular cut out in the sloping rear wall and drill some holes

Hi Derek,

Top machining skills. I love viewing your work.

Thank you Keith.

Only had a short time in the workshop today working on the Farm Boy as I was sorting and finishing a bowl which I did a demonstration on yesterday afternoon.

Rear frame main machining complete finished the rear cut out section for the con rod big end to revolve freely. This had to be done at an 8deg angle which made it a little more interesting as well as the centre of the radius needed to be 0.270 down from the top of the rear frame. Still some small holes need drilling as well as the crankshaft top caps need to be made before drilling out for some bronze bearings.

Very little done today found a lump of ali chopped off a piece, squared it all round and machined to final thickness. Cut a piece off the end and cut this in half before machining the other measurements to the final size for the crankshaft top bearing blocks.

I also spent some time cleaning up the inside rear corner which had a little step in it all be it less than 0.005 but still visible and it would have annoyed me seeing it even if it is partially hidden when this is complete.

Still one main large piece to machine then it is onto all the little bits and pieces which should be fun

I am waiting for some BA fixings so that I can drill some of the holes in the rear section of the frame, so I thought I would start on the hopper assembly well the hopper top at least. The fitting I am using are the closest ones to what the plans state as BA are easier to obtain as well as I already have taps and dies in BA
