Thread: Rotary Table questons

Your shed doesn't have A/C?
In theory mine does. But they are evaporative so I'm not game to use them as coolers with all that cast iron just waiting to go rusty, so I just use them as fans.

Well I was right, the vernier for my tailstock turned up today. For $8.13 delivered with a spare battery. For the price its pretty damn good.
Off to the shed.

That's a great deal! I bought some from Aldi but they were totally crap and over twice the price ... plus the fuel to go get them ... twice, since they were initially out of stock! Bought three pair for $20 each, opened one and then threw them all in a drawer in disgust.

I did a quick test, I'll post it in the other thread.

I bought 2 from Dick Smiths a few years back and have found them to be the best I have ever owned. They have auto on/off and are still going on there original batteries.

I would not spend the money on quality verniers because even the best are only good to around a thou (0.0254) That money would be better spent on good quality Mic's.

In contrast I use my Mitutoyo callipers to death, and love them. As Dave mentioned, where serious accuracy is required then it's time for micrometers, but I find I rarely have a need to get mine out as the Mitu callipers are remarkably accurate. While I bought mine used through Yank-bay, they're probably the one tool I'd have no hesitation in replacing with new ones if these ever pack up. Like many things, there's a place for cheap alternatives, and I bought the cheap Aldi versions to hack up for tailstock readouts etc where supreme accuracy is typically not required, but I wouldn't recommend anyone use anything like that if they were relying on them as their primary measurement tool. I think if I had to name the one single tool I use the most in the workshop I think it would probably be those callipers, so in my humble opinion worth spending the money on to get reliable and accurate

Pete

Edit: sorry I should add that if you're able to get good, reliable, and accurate callipers inexpensively then I'd say go for it, it's just that my experience at that end of the price spectrum has been a little disappointing.

I don't really like batteries in my shed so bought mitutoyo dial verniers. Not my favorite tools I must say. I think they are much slower to read than a normal vernier and much slower to use. Although the small one does read to 0.01mm but really if you need that its time for the mics.

Wouldn't hurt to take the 3mm out.

Dave

I wasn't going to machine it out Dave. Just machine the radius on the top and bottom of the nut, if they have extended the uncut at the end they would both have the same center.
Its all about how pretty it looks lol
I shouldn't have to extend the slot. I'll see in the morning.
Stuart

Is that a picture of the nut your making?

Dave

To save fooling around with a couple of PMs, there is something in the mail for you both. Chuck it out if it's of no use.
BT

It could be lol
It was meant to be a sketch of the T slot from above(with out the hiden outline). Showing that the cutter used to cut the top of the T(the bottom/wide part of the T slot) stopped about 1.5mm short of the cutter that cut the slot.

Thanks Bob, will let you know when it turns up. As for chucking tools out I don't throw anything away. I still have old garden tools etc here from 50-100 years ago that came with the house.

Stuart,
I will check mine tomorrow to see if it's the same. I took it as a sketch at first, then thought it might have been the T nut.
Is it that tight getting the bolts into your 120mm adapter? The holes in the adapter could be slotted instead of a drilled hole, just like the way the rotary table is. It might buy you that few mm you need.

Dave

Thanks BT I'll be waiting on the posty

I'll measure it up properly tomorrow Dave. It should fit. I think the 8mm holes need to be 7mm for the edge.
