Cheers John.

Yep, I agree John, no limit to the number of ham fisted trades people who ought to know better, but after doing a bit of reading on that link cueball posted, it seems like this is a bit of a weak point in Deckel's design. the Tbolts are standard "unbrako" and the support area is pretty small, this is what Willfried did to his FP3 which had the same problem..

This picture shows Wilfried's improved T nut design versus the original unbrako. Not altogether surprising that they fail at that point.

I like this method of fixing the problem...

To repair our's we'll have to make new t-nuts large enough to bridge the damage in our T slots

You can tell from the crack it was a tradie that did the damage?

One change I would think about making to those Tee nuts is to use a smaller thread in the nut.(as I did on mine lol). There isnt a lot of meat left either side of the major dia if you make the nut with the tee bolt thread size and they can crack down the sides.

Yes, very professional looking damage... I was thinking that with your super-power skills would be able to tell the guy's name and address...

Ray, if you give me a rough idea of diameter and thickness allowing for machining also bore size I may have a chunk of circle cut plate here you might like.Make a big tee ring pcd it drill and tap holes and cut out your pieces ad lib. got some spares too.
"Why strain when you can go by train''.Cheers John.

Thanks John, I appreciate the generous offer.. we are still trying to figure out the best approach, so we aren't quite ready to accept your kind offer just yet..

In the next few days I'm going to measure it up properly and figure out what the best approach to repair is, the top and bottom of the t-slots are pretty badly mauled apart from the missing piece. I expect that a proper repair will require replacing the whole t-slot area.

Still thinking...

I cleaned out the coolant tank, well mostly.... So much for the swath trap...

ok Ray there is a swag of round stuff here if that is the way you want to go.Am an old ''junk aholic'' inherited in fact. Will keep my chair warm for the progress up dates Cheers from frosty Newstead brrrrr.

I had been looking for a thread on PM where Ross "AlfaGT" executed a tee slot repair on a Deckel . Haven't found it yet because I was waylayed by this thread showing the handiwork of Tien Nguyen Binh. If you haven't yet seen it, I reckon it's worth a look.

Deckel table fixing plate machining - Lots of pics

Tien has a collection of machine tools most of us can only dream about. Knows how to use them too.

^^^ Forgot the "Alleggerita" in his handle.

I assume this is what was sought....

FP2 Vert Head "T" slot repair (Large)

someone else has a dropbox of all the various pictures now missing, can't remember the author though.

An auction a little while back had a LB bed being used as a welding bench, don't know what it was, but appeared much bigger than typical FP3LB.

Well I did, but the address turned out it to be an engineers.

I dont like the sound of "replacing the whole t-slot area". The way I'm looking at it*, you have more than 7/8th of the tee slot still there. I have trouble seeing how your repair will be more rigid than that. Though I'd never rule out you two coming up with something that makes me go

*with long nuts and a spacer(which it shouldnt be to hard to hide)

Agreed I would have to hide it even knowing it is there is enough.Seen too many 'striped apron' stupidity over the years,termites white ants prangs and busted castings.

There were two different tables available for the FP2LB ( and FP3L) the universal table which tilts and rotates every which way, and a fixed table that could be had with an extension, that would have a pretty big table.

I found those pictures on the wayback machine, Plus other stuff metalworking.com - /DropBox/

I'd like to see a cross section of the t-slot and how much he had to machine out of the slot to do the repair.... I'm worried that we will end up with not enough thickness..

EDIT: Here's the FP3L showing the supplementary table mentioned above.

Your powers are undiminished.... I'd come to a similar conclusion, except that engineers don't make mistakes, they make design improvements,...

Thanks for that BT, I'm in need of a dose of inspiration ...
