I went to use mine the other day and they were flat also mind you I have to wonder if my son used it or not I'll have to pick up another and try round 2.

trapper:
Really enjoyed following your project obviously a very good all round machinist-keep them coming very well presented as well

SwarfnStuff:
Thank you for the life span info of your batteries Abraham. I shall try some new ones and leave em in then see what happens. Wouldn't care too much if they weren't the more expensive size. There is an inclinometer app in my phone but naturally the phone body is slightly curved to assist handling - bummer that doesn't help.

Hi all,

Trapper,
Thank you for the comments.

Got a bit more finishing done.
The ends of the anchors also needed some fake draft, but as they are “complex “ curves and angles, they were milled on the CNC router.

Then the lathe broke down and spent a few days to repair it.

Printed some gaskets on gasket paper and made a few hole punches to cut the small holes.

Turned a mandrel for the piston to cut a groove for packing.

Also made a new piston rod from stainless steel.

At the moment busy polishing all the brass bits.

Cheers.
Abraham

Hi all,

The corners of the bearing posts and bottom crosshead guides were rounded over.

For accessories am adding a governor based on the one from Elmer’s twin rope drive.

For the throttle valve cover started by centering a piece of brass in the 4 jaw.

Machined and threaded the boss.

Flipped around the end was faced.

For the throttle body started by drilling the valve bore and cover mounting holes in a squared and to size piece of brass.

A pilot hole was drilled through the length.

The pilot hole was used to center the part in the 4 jaw.

A boss was turned, drilled and taped.

It was turned around and the other end was machined, unfortunately the photo did not come out.
The valve shaft was turned for a close fit in the body.

The parts so far.

The throttle was assembled and the pilot hole located to drill the passage through the body and valve.

Had to mill a piece of hex stock to a smaller size for the gland nut and lock nut.

It was drilled and taped in the lathe.

The nut was parted off.

Both nuts done.

And assembled.

The various linkages were machined.

That’s all for now.

Cheers
Abraham
