The one used on the video above has bearings to roll the crankshaft on. I don't like this because bearings always have their tolerances and play which adds unnecessary uncertainty to the measurement. V-shape wedge is better and if you are worried about leaving a slight marks on your crank bearing necks, you can add a strip of softer metal to the edge. This should not be necessary though, because you will not be spinning the crank on the stand (at least hopefully) for thousands of revolutions. Smooth surfaces on the V with dab of oil and you are golden.

1. Make it beefy enough - you don't want to guess if you have flex
2. No need to make it very tall unless you want to use if for some static balancing action
3. Adjustment for crank width is nice to have
4. Get two dial gauges with mounts to see both sides of the crank at same time

My vision of a stand coming together. Still going to shape the ends like V and line them with some softer metal like brass. Plate is big enough to comfortably mount magnetic stands for dial indicators and there is a possibility to drill additional holes to accomodate almost any crank. If one side has a bearkng sleeve, washers can be applied under the holding arms to compensate.

I managed to get it within +/- .001" (about 0.002" total) on each far end by using the video above. Is that good enough? It's a lot closer than it was. For now, it seems each side is asking for the opposite correction of the other side, so this is the happy middle. Probably means something about the pin itself or about my measurement steadiness.

I'm not sure that I dare to reinstall the collar and use it. Do I?

Lucky for you, you Know A Guy who has a couple smallie cranks close at hand.

65mm is going to be pretty wide, and definitely can't be done with a bearing race/bearing in place.

Thanks, C'man!

New iteration should work on any crank, with or without a race installed. Height/width adjustable.

3/16 x 1 1/2" aluminum flatbar riser. One tube fixed. The other slides horizontally.

Getting past the $20 fixed 65mm plan, but maybe you guys can get some ideas. If I did it again both posts would be adjustable aluminum landings.

other key lessons from today:
-sneak up on your adjustments, but you will get a feel pretty quick how hard to hit things. I had a bit of spread going but I used the vice and ended up in squished condition - I guess that was too much, but a quick hit with a wedge and it was sorted. The majority of my issue was twist, as suspected.
-a big brass drift about the width of a hammer handle works well with a regular hammer if you don't have the brass one
-that guy in the video knows his stuff
-don't try to judge if you've succeeded while the crank puller is still installed and the other case half is not - it will freak you out unnecessarily. the crank was hitting the rotary pad until I removed the cantilevered weight.
-don't order the new parts until you are sure the old ones are trash ROFL emoticon

I can send you the prototype in the video for $0 + shipping if you want to try it out.
Just DM me your address.

I'll make another 4 next week, both landings aluminum with CNC'd landings/channels, and put 3 in the Classifieds.
