Very nicely banged -together press, Eugen! I love it.

@Eugen I love your little press fabrication. It is fitting that you used Case parts in the build. The GT lift plate is one item that is recognizable.

Ingenious!

Thanks Eugene! It's called a "lift" plate for good reason. You saw how it lifts

For the Canadians here, I'm really pleased with this 12 ton bottle from PA. I got it on sale for less than $30 and it's the type that can be used in any position, not just upright; it's small enough to handle and take places yet strong. Together with the little welded contraption it makes a nice mini press. As they say, it ain't stupid if it works.

I've never even heard of a bottle jack that works in any position.

I've torn Jack's apart and modified them to work upside down but I've never seen one that doesn't care.

Maybe I interpreted the "multi-position" in the title too enthusiastically. But it does work horizontally as well as vertically. Not sure about upside down. Hopefully I didn't mislead you guys.

I'm not throwing out a challenge. Maybe they have figured out a way to make it work in any position. I've never even heard of one that work sideways. So that's still pretty cool no matter what.

Reaming the bushings was quite nerve wrecking. As @Spike188 said, you need to worry about the hole being true, that is, parallel to the crankshaft. I had other worries besides that. This reamer is the absolute cheapest at $100. Logically the build quality is not the best. After it arrived I took it all apart and inspected it. The grooves for the cutting blades were quite rough and had some swarf from the manufacturing process. The cutting blades did not seem made with a lot of precision. I washed it well in diesel fuel and tested it. Took me a while to get the adjustment dialled in, but eventually I got the hang of it and managed to get all four bushings reamed. I didn't want to risk and cut too far so I went with very small increments, making sure the reaming turns were smooth and straight, with no chatter. The best feel for it seemed to be like a beard shaving sound, a schrrrrrr. It did not feel like cutting, more like two surfaces gliding with some friction. I kept on trying its assigned pin until it fit with friction. I used a little abrasive to finish. The clearance the measured within spec between 0.0008 and 0.0014. @Spike188 , if it'll just knock when starting and work for 39 years I'll be happy.

No oil on that while doing it. Just wondering. Ya, don’t mind me, I know nothing, just asking.
Gunna work great Eugen.

Yes I put oil of course, lots.

If the bushing were sinthered bronze I'd have not used oil. They seem to be made of an yellow reddish alloy, some sort of brass. They shave nicely and I oiled the reamer on every adjustment.

A very rainy day. I had plans on getting the block ready for the sleeves but I can't do that in the rain. To feel like I'm doing something I just put the rings on the pistons.

Nice to see the progress you're making Eugen! Great build with the press.
