Thought I'd share this simple modification I did yesterday to my forecast wrapper. Quite some time ago I upgraded the chuck to the ALPS chuck, and thought that that was the best mod yet...well it sure was but I still needed to upgrade my carriage to a horizontal like style and able to do 4 thread tigers, minimum...so here it is. I found the jamb bracket at my local Home Depot and the various hardware also. Very simple modification that fit the stock carriage like a glove! That wheel I had installed some time ago and what a difference that made also, no more bumping the carriage off track for whatever reason. I'll let the photos do the talking. Hope this helps someone out. I sure wish the factory power wrappers like PacBay/Forecast/ALPS came with this style of carriage.
