Wonderful to have you all along, I could not have done it without you folks all helping me!  Just the last couple of chapters to write, and wait for the Lombard series to finish up next spring.

Hi Chris,
 This sucker just keeps getting bigger & bigger!

Have you been checking the elves mail lately? Wondering if there subscription to Charles Atlas Body Building for all arrived yet?    :lolb:

Just a suggestion....... on the hold down strap thru the cab, can I suggest a block under the cab so when you pull up on the strap it pulls down on to it. Helps to prevent thing bouncing around..... the last thing you won’t in 100 pounds of carefully crafted metal getting lose in a confined space with you present!

Cheers Kerrin
Get excited and make something!

Hi Kerrin,


Not sure where you mean, a block between the base and the frame under the floor? Or between the strap and the cab floor?  The way it is now, the strap runs across the cab floor and down to the base on either side.

Getting to work on the valve and throttle bearing blocks this morning, started with fitting the blocks for the caps and drilling the cross holes for the valves and throttle, also the holes in the lifting rings behind the bearing blocks:

Next will shape the tops of the caps down to size...

Caps trimmed down and bearings made/installed, these are simple tube bearings so quick to bore/turn/trim to size.

Next I think will be pistons and crossheads...

Chris:

I know that Velcro is the greatest thing since sliced bread, but are you sure those straps are going to hold?  I've no doubt that they'll hold under normal conditions and keep the model from sliding around.  But I've got a what-if for you, what if you get into a situation where you are braking hard, are those Velcro straps gong to be enough to protect you from the model?

Just playing Devil's advocate here,
Don

I think so, the blocks around the tracks take most of the load, the straps hold them down into them. There is 6 inches of overlap per strap, and the straps are bolted down. There will also be rope around the boom and the handles, and the base will be tied with rope to rings in the cargo deck.

Changed my mind on which parts to make next, going to do the stand which holds the steering engine up vertical on the cab floor. This is made from some sheet stock, rough cut then trimmed down on the mill, clamped to the wood block I used when making the booms many moons ago.

Here are the parts shaped to outline, next will cut the openings in the vertical plate and the base plate, then can drill for some temp screws to hold it all together for silver soldering the joints. I assume that the openings are there for access to the big end caps and to allow the rods/eccentrics to slide in from underneath during assembly, maybe also to reduce the amount of metal needed in the castings, the openings are there in the original.

Chris, this is the first time I have seen the hold down clamps used with a block of wood, now the choice becomes what wood to choose? Hmmmm would save me from removing the big vice and then having to square it all up again.

If you can imagine it you can build it

Good morning Chris,

Boy that penny in the photo really brings to scale the small size of that engine. Beautiful job :ThumbsUp:

Have a great day,
Thomas
