This is what I did:-
Remove the furniture from the roof sealing the holes with CT1 sealant, and take to my workshop.
|Removed from the roof to my workshop.|
|Clean and deburr the feet.|
|...and tap M8 through.|
|This ensures hole centres remain the same after extending the upper part.|
|I later changed the countersunk screws for cap heads to provide a little flexibility.|
|Mill this end to clean and mill the rebate, then mill opposite end to length and rebate.|
(For the eagle eyed, I did square them up in the vice before machining).
|There's no going back now!|
Mounting upside down in the machine vice, mill the cut face to clean and then mill a rebate to match the block. Then do the same on the other half.
|Machine a rebate to match the block.|
|It's ready for soldering.|
|Silver soldering the joints.|
|First two joints made.|
|L/H joint completed.|
|R/H joint completed.|
|The (nearly) finished item.|
