Usually I'm on forums asking for advice, today for a change, hopefully im adding some useful..
For those out there that wanna do certain tasks on the bike such as oil changes and rear wheel removal but havent got a jack, its pretty easy to make one. I found a vid on youtube when searching for jacking points as need to remove my rear wheel and thought id give it a go..
1.You need 2 lengths of wood and decent 3"wood-screws. 10*2 plank by 10 ft of wood and a 5*2.
2.Cut two lengths of the 10" to about 3ft and 1 to 3ft - 5"
3. Cut a length of the 5'' plank to about 4 ft
4. Sandwich the 5"board between the 3 pieces and SCREW them in place. The shorter 10" piece sits in the middle of the 3 to accommodate the lever.
A home made jack for $14. The 9 remains very stable once up but you have to get it over the odd sensation of -- is this gonna land ok ?? --- as you lever it. Feel free to burn me..!
