I have a large commercial (ex launderette) washing machine in my workshop. I initially fixed it down with Rawlbolts (expanding anchor bolts) These washing machine unlike domestic one, have no suspension system and will literally leap around if the load is uneven. First set were pulled out by the movement. I over drilled the holes in the concrete and fitted the next size up. They suffered the same fate. I blew the dust out of the holes, half filled them with the resin intended for chemical anchors, and pushed M12 studding in until the resin rose to the surface. Left 'em an hour to set then torqued them down. That was two years ago and they are still rock solid. and that was with M12 studding in a hole that must have been far too big according to all the instructions as it was at least an inch by then. Since then I've sworn by resin anchors but always just use a bit of studding and anchor resin from a 'two pack' like this:

How dose the epoxy compare to say red head anchor bolts?
I have been considering anchoring a bench down in my carport, it's asphalt and red heads won't stay put in asphalt.

The epoxy won't hold any better,

They used those chemical anchors at a place I worked at over 20 years ago. The guy using them failed to blow out the hole properly before inserting them so they failed to bond properly. Good idea maybe, but a waste of time if the guy using them doesn't read the instructions.

I've put up a 12 foot tall cast iron lamp post with a flange base held down by four chemical anchor studs at my place, and had to lean a ladder against it to install the lantern only a couple of hours after tightening the nuts - they held ! But I did blow out the dust !!!!!

I have no idea - sorry. I see that Dave has already answered though.

A friend had a two post car hoist installed, they used anchor bolts similar to the red head ones, about 3/4 inch dia. They came loose. They came back and used epoxy on them and they held.
When I bought my hoist the company said to use the epoxy. Its a two part for bonding to concrete. You apply the epoxy then let it set for a couple of hours before torquing the nuts. Mine never have moved, tried retorquing them and gained nothing.
Free advice is worth exactly what you payed for it.

Sorry guys I haven't been back with ya on this lathe repair work but I've been deliberating over whether or not to use these repaired gear or not.

I have been contacting any gear making shops to get a quote for making new ones but, they just won't do a small job. nless they can suck my wallet dry. they actually quoted me more than the lathe cost new. i believe it was their way of saying get out of my hair.Bash

Hello , I have gotten gears a few times from Boston Gear , through MSC . I think you can go to them directly also if you want they have everything , I bought a new gear for My Cincinnati lathe last year , worked perfectly . http://www.mscdirect.com/BostonGear
Hope this helps

Hi
A comment on epoxy anchors…… 30 years ago, where the old Battersea power station stood in London, they build a Yuppie apartment block, The elevator / lift was built on the outside encase in glass, you can see it ride up and down from the outside, anywho…. I installed the motor and winch plinth for that elevator weight 4000lbs approx. by drilling 8 1'' studs upside down into a reinforced concrete ceiling, sinking the glass vials in then smashing them with the stud, twisted them with the drill to mix it up. Irony of the story too is they hung the whole elevator / lift from the same foundation.

Been reading your woes on this lathe, if you really want this machine working again then money needs to be spent, then the question arises, what's the best return for the expense laid out.

I know your new to machining so here is your chance to get more experience, I would purchase the correct machine tools to make the required parts, you benefit all round as you learn more, gain more machine tools and fix the lathe you have. Granted it’s a long term project for you but nothing is fast in this hobby, another plus is this the expense for the new machinery you purchase will be worth exactly what you paid for it, if purchase wisely used machinery is a wonderful investment, I would suggest you keep an eye open on your local auctions and Craigslist.

Just a thought….

Anthony.
