I have spent a great deal of time on this piece - more than i should have considering it's value! But have enjoyed the time in bringing him back to life. I found the plastic pipes were too light to work the tip - filled one with a bit of weight and she worked - in a fashion - then i found - by chance three Logs! perfect and a little more weight - did work but could not get them to fall in a neat pile to allow the wagon to move on!! Then I was starting to lose patience and decided to "Shut up Shop!" and list it as working sometimes and in need of some different expertise! Even if one used it sparingly with the Grankids, and then placed in a siding with tipped load - Surely would look good in someones Layout!!           Just had a brainwave!! After reading my screed once more - what if I was to use only two logs!! EURIKA! Tried it and she worked perfect - just like she should!!! Flipped back to upright and ready to go - both logs fell neatly ! Will finish like that now on a high note.
