Hi Nuno,
You could always sell the one you have and buy 2 new ones.
Might work out better in the long run.
Ian.

try using warm/hot water.

Depending on the glue this may work

With all due respect Nuno, if you have to ask if there's a way of unglueing plastic parts you'd be better off following Ian555's advice. Knowing the limitations of my modelling skills, that's certainly what I'd do

hi Nuno,
Ian's advise is the best i think... if you have some space on your layout you can choose the current special autumn offer of FALLER, article no. 190186, which is derived from the formely available freilassing roundhouse model (ex-POLA). each set 190186 gives you a 3-stand shed and additionally 2 water hoses and a stationery crane, at the 'official' price of 30 euros. if you take into account the price of the former 5-stand freilassing shed and the accessories a very attractive offering, i just ordered 4 sets of them (with another remarkable rabate) to extend these 'old' sheds.
and your 7288 can be sold at ebay....on the other hand you need about 30% more space in one direction because this one is a 7.5 degree shed which in turn gives you a full loco length between the turntable and the shed.

Hi all

Thanks a lot for your tips. I glued the kit with UHU plastic. I found in the market, together with the glues, a product called "Unglue everything", I think I'll try that first, carefully. Or maybe the hot water first... The Dremel won't work in this case, the pieces are "dented", they match together like gears, you see...

To sell the kit is out of question, as you may know Maerklin does not sell it any more in redish colour, now it is yellow. I was lucky to still find a red one (it was the last one at my dealer).

Cheers,

Nuno
