Are the Base and Column Separate on a Lagun FTV-4?

A Lagun FTV-4 showed up on auction near me. It's listed as having a "cracked base." I assume it was damaged when moving at some time and broke the "toe" under the table and in front of the column. I'm not familiar with these machines, in pictures it looks like the base may be a separate casting from the column, is that the case? If so is a new or used base obtainable? I expect it will sell very, very cheap. Just trying to figure out how viable repairing it is. Thanks for the help.
 
I don’t know much about that particular machine but over here in the UK we have several companies that specialise in the cold repair of cracked or broken castings. People like “ Loc-Stitch “ . “ Meta-Loc “, “ Surelock “. They all basically stitched the castings back together again. The company I worked for employed a “ Dad and Lad “ team that could cold repair anything, when they’d finished the job was a good as new, possibly better.
There must be similar organisations in the US.

Thanks for the thoughts, Tyrone.

I'm in a very rural area so that isn't super accessible unless I haul it around somewhere that can do it, though there are definitely places capable of such work. I have a local friend that is an old time self taught guy, he's fixed a lot of cast and could probably braze it together and make it serviceable. He might really hate if I hauled this project into his shop, though. :willy_nilly:

None of it may be worth messing with, even if a replacement base is viable. There is only one very poor picture of the machine in the auction listing (that doesn't really show the listed damage) and it seems to me that whatever broke the base could have caused other major damage that may not be as readily apparent.
 
I do not see any reason it would be. Where would you find a donor base anyway? AFAIK they do not seperate on a bridgeport or clones.
I tried on two drill presses and could not pull the column out of the base even through it is theoretically possible.

Thanks, Bill

You could be correct, I know on a Bridgeport and others similar they are not. I ask because looking at pictures these are constructed slightly different and that the base and column appear separately cast. Very possible they just *look* that way. As you say, used parts aren't looking very available regardless.
 
I have seen pictures where people graft a different head onto an older base and table. In theory a mounting plate adapts the new head onto the old ram arm.

I spoke with Lagun and they confirmed that the base is separate and bolts to the column. They are looking if there's a base floating around somewhere. Are there any machine tool salvage places that might be parting one out?
 
Well... I own it. It is in nice condition with seemingly little wear. I will have to make a game plan to repair the base, I'm leaning towards trying to braze it then maybe bolt some steel plates to the sides for reinforcement. I have $300 in it, I figure if I decide it's not worth messing with the parts and scrap value will easily get me that back out of it.
 
Here's my new misery, haha. Even came with a nice working Fagor 2 axis DRO and Kurt power drawbar. Gentleman at Lagun said the riser is quite rare. Ways the saddle sits on look chrome to me but no tags indicate as such.

Definitely a job for the “ Meta-Loc “, “ Loc-Stitch “ guys. The man and lad team I used to work in conjunction with would fix that as good as new, no problem. How did it get broken ?

being the column is separate you can readily fabricate a sump/base out of plate. Brazing that is possible, getting and keeping knee screw square might provide some challenge. Looks like someone already tried to repair it once and gave up after alignment issues.
