In Readiness for this weeks Robot build I ordered a couple of clamps on e bay
and they arrived just in time for use this Sunday.
Unfortunately due to the bad weather, Adam was unable to come through this
weekend but hopes to make next Sunday.
During the week I had time to weld in place the retro fit sprocket to the winch
and managed once again to get it spot on straight.
Today I worked on the Jaws and a possible way to drive the winch sprocket
through the narrowed gap created by the drive reducer sprockets.
It turned out that there was just enough space at the side of the reducer strut to
run a line of chain up to the front mounted motor drive.
To make this idea work meant moving the winch drive motor to a more internal
position and thats where the clamps came in to support the motor.
Upon fitting the chain in place it looked like needing another half chain link, so
rather than settle for that I decided to enlarge the adjustment slots on the winch
so the chain could be easily adjusted.
Lastly-I noticed one of the drive reducer sprockets chains was slightly tight so
I slackened off the drive motor and added a metal shim under the clamp to lift
the motor and so give a little slack in the chain.
There are still the jaws to re fit but thats just a ten minute job and theres no
reason to think they wont work as well as before.
Next week we will probably concentrate on the electrics and get them to
competition standard.
Heres some photos showing the clamp and the chain from the winch up to
the winch drive motor.
