Default Matt Francis Timing Jig & Break-in Stand

I just bought one of these neat looking things today and it has already started to disintegrate.
The Acrylic plates have cracks all through the holes that the stand-offs mount to. This happened after running just one motor on the stand for break-in.
Anyone else have one of these things?

I've had one since they first came out months ago and have had no problems at all.

Mine hasnt broken either. Did you tighten everthing by hand or did you use plyers or something to try to attach to the posts to the stand. I just installed everything by hand, I think you might have messed it up if you overtightened the stand.

Default OVER Tightening!!!

Well, maybe a little. I was concerned about vibration causing it to fall apart. I just put CA around all the cracked areas and it seems to be holding up fine.

Thanks,

When I built mine, I put an 0 ring between the posts and the plate. That way it didn't put too much pressure on it, and the vibration didn't cause the screws to back out. I had a shock dyno, and I made the mistake of putting a little locktite on the screws and no o-rings, next morning all the ears were cracked around the screws. I know you can get a new top plate for the shock dyno (Found out AFTER I threw mine out, doh!) so maybe you can get one for the break in stand as well.

Trinity was selling them for like $13 at Cleveland... how much do these retail for? Anyhow my friends pick them up and has not had a problem with them yet. I think the over tightening of them with the acrylic will cause cracks due to vibration. Best to leave them hand tightened...
