Re: Help - Can't figure out way to connect spool to webbing

Howzit!!

The picture has gone through and is now posted..

Here is the link

You can see the recess for the bolt and looped end of the strap.

The spool is printed to use the 1/2" hex directly out of the transmission.
We basically mated two Vex Pro 2 CIM, 2 speed transmissions together. one used the motors and two speed selection really helped when the load got heavy.
The second transmission was setup to shift between a free wheel spin and a one way ratcheting system. We just used a ratcheting wrench and cut a small hole for the reset of the wrench it to stick out of housing.

If you are interested I can post pictures of the assembled winch system.
Or CAD files if you like.

Also as mentioned it would be a good idea to get that motor and spool down into the chassis. Yes the strap will be longer but it will not affect the amount of strapping you need to winch..

Our system was gravity return and with the weight of the tool we never had an issue with the lift lowering when empty.

Good luck,

Aloha.
