Hi,
Was doing a bit of reading here and googled for some info. My heli does suffer vibes hence, I was looking at getting this

The first one with the stand in the list.

I havent got a clue about these tools, so any help would be much appreciated.

Will this do the job for the heli purpose. Or should I be looking at more expensive ones? I have a vice but its not big enough to hold a 50 engine, so will be getting one big enough. Would I be needing anything else apart from these?

Too many Qs

Thats a pretty decent price for that one! They are good to check if you have a bent crank, runout on the fan,clutch issues, sloppy bearings,bent feathering and mainshafts.etc. the list is endless. you won't use the magnetic base much tho.
a pair of dial calipers will be an asset to have also.

Smile! people will wonder what you're up to!!

thanx flipped2left,

As long as this one comes handy for runout on fan, clutch, I will get it.

My next step would be to learn to use it

It is easy to use - if you need help, just ask.

You can use that setup for many other things (cars, bikes, etc)

I would definately verify the resolution of the dial indicator.

I found that 0.01 resolution too big so I recently switched to 0.001 (but that one set me back 75 euro )

I still find it very hard to properly dial indicate the fan / clutch.
As soon as I think I have it right (less than 0.010 run out) and I tighten it up I find that it is out of alignment again (from 0.010 to 0.050). I have now settled (after an hour of work ) for 0.015 which I think is still pretty much(but I started with 0.080 )

Greetz,

Marc

I prefer a couple of vices. One to hold the engine and a ball vice to hold the dial guage. My bench is chipboard so a magnetic base is useless.
Its obvious how to use it and you'd be supprised at its uses.

poerQwa has a good point. I would go with the DT1 - SPECIAL OFFER Dial Test Indicator with that base.

You do not need to spend too much on the calipers. You should be able to find a set for the = of $20.

DT1, yes, that was the second one i was looking at, I had read somewhere that Digital Test Indicators are more precise than Digital Indicators for some reason.
Yeah, one time investment.

My work bench is ply wood, so i guess i wont be able to use magnetic stand , they dont seem to sell anything other than magnetic ones. Would i be able to get one from Homebase or B&Q type of places?

The weight of the stand will do just fine. I use a wooden table with mine.

Not sure what you mean "Digital Test Indicators are more precise than Digital Indicators for some reason."

You dont need a digital indicator.

I found one, it says .500" with a .0005" graduation
What does that mean? does that mean 0.0005 resolution?

I think you want this style:

I believe mine is 0.030" travel in 0.0005" increments


EDIT:
digital is more accurate since you can have higher resolution. For what you need, you dont need to spend the money on digital.

The stand shouldn't matter too much, but I think I prefer this one

Plus the ball one is more $.

I have the magnetic base and the indicator that I showed in the pic above. I use it on a wooden table with no problem. However, the magnetic base would come in handy if you do your own auto repair.

The tip on the indicator can be 'moved'. Hard to explain....once the gauge maxes out, you can move the tip up or down more by pushing it slightly harder.

If you need help on how to use it, post here or PM me and I'll giver you a hand.

Make sure the indicator comes with a dovetail holder. This is how you get it to stay in the base.
