No problem getting the bench delivered and in to the workshop!

They just poked it right through the door and onto a set of load skates!

Plenty of room for the lathe!

Mill in position and look at all the clear space in the workshop!


BUT, disaster! Major cock up! I mis-measured the mounting holes for the lathe tapped inserts! What a blankety blank idiot! Now I will have to make adapter plates of some kind!

Easier to drill the bench and resin-fix a knurled socket into the hole John. Then you can still keep your clean lines and the ability to un-bolt.

How far out is it?

WOW

That is one heck of a lathe stand !!
Is there a thread I am missing that has the details of it ? If not, please add some text !!!

Wonderful pictures BTW.

Thx

Peter, three of the holes are about 20mm out.

John,

My Wellington friends are frolicking in their first snow since 1975. I see you got some too, perhaps not as much.

Is this a custom made bench, to your specs?

Allan, we had our snow on Monday, its nearly all gone now.

Yes, I was asking around for advice about casting concrete and this company made me an offer that was quite attractive so here it is. Unfortunately my specs were lacking a little so now I need to adapt to the holes being in the wrong place!:o

Well, at least with the concrete being new, it shouldn't be too hard to drill with a proper concrete bit. It would almost seem that you should drill all new holes, and re-position the lathe so the new holes don't come too close to the existing ones. Seems like it would be easy to chip into an existing hole and bugger up the new one.

Or- is there a possibility of drilling new holes in the lathe flanges to suit the existing mounting holes-

Turn the table 180 degrees around and put the new holes on the other side, the old holes are now.. 'Fixture holes' for when you need to uh, fixture something to your bench...

That would be OK except the drainage gutter has an interruption where the headstock is supposed to go and there are fittings cast in the legs for mounting the brake pedal. But nothing is impossible.

20mm out is hard, could do with being a little more.

Well, 12mm studding (all-thread) will hold over a ton so plenty strong enough, so you could drill 14 or 16mm holes and resin some 12mm stud about 70mm into the surface, or drill right through and put a nut and washer on the bottom but you risk popping the lower surface and making an ugly scar. Tell you what I'll come and drill them for you if you pay the petrol :D

Just make some raising blocks. This way you can offset the holes enough.

I have eaten my dinner and went through to thoroughly investigate the situation.

The error is much, much less than I thought in fact it is about 4.5mm, makes it hard I think so I might just have to use some of my bench top real estate and move enough for a new set of holes.

Peter.
08-17-2011, 05:36 AM
For that little can you not turn some offset studs?

Hmmmm.... good thought...


Thanks everyone for the advice, I will head out to the shop first thing in the morning and double check the situation and hopefully get to some sort of solution.

How old is the concrete? Don't forget that concrete shrinks a little when its new, so maybe don't tighten the lathe down too hard till its a couple of months old.

Concrete is about a week old.

Richard's comment about new concrete shrinking has me wondering if the holes are too close together or too far apart. If the former, I'd put on a real straight face and say it was shrinkage that accounts for the discrepancy in distance and not a bad measurement. :D

For 4.5mm I was going to suggest off set studs turned up as well, but see it has already been mentioned.
From memory you where going to grout after woods so this would cover them up.

Unfortunately the holes are too far apart!:) Maybe if I wait a bit they will come right?

You'd need a (large) micrometer to measure the shrink on a piece of concrete that size.

Thats sad, I was hoping to get a bit more clear space around the back of the bench.:)

4.5 MM is only about .188. Couldn't you enlarge the lathe mounting holes to take that up? Or maybe elongate all four holes.. You wouldn't be removing that much meat.

Absolutely..... enlarge the holes, possibly cast in some epoxy to restore the "form" of the holes.

I can't see moving the "whole" thing just because of a tiny error like 4.5mm. (In regular concrete work nobody would even NOTICE 4.5mm, most likely.) You already had the holes in the best place for use, any move will be a pain for years to come.

So just grind/cut/whatever on the side of the appropriate holes until the machine fits.

i suppose there is no chance of just using undersized studs? with the machine grouted to the top, almost anything should be enough to hold it down, so undersized studs are unlikely to cause a problem.

Don't misunderstand me, at a week old it will still have a bit of shrinkage to go, but we are talking small fractions of an inch, nowhere near enough to make the holes as far wrong as they are.

You are right, the general tolerance on concrete work on construction sites is around +/- 6mm.

John,

This looks like your (New?) Ashburton House??

Grant,

Is this house in your New Plymouth neighborhood? I took this photo from the beach right in town, on a rare day a year ago when Mt Egmont was out of the clouds.

Who lives in this palace?
