jig adjustments

I haven't had the funding to work on the bike projects lately so I been reading posts on here a lot and decided to make some changes to my jig to make it a little more easier to set up . I originally set it up with 2 different posts one for the motor and one for the trans .after reading some posts by some more experienced guys on here they made me rethink that I noticed it was a pain to reset both so I could keep the space right between the two . I was going to make a single post setup like they did I think it was concrete guy but not sure . I happened by bitter ends website and noticed they sold a setup real similar and watched a few videos on how they set up their jig so I bought their motor and trans plate setup and fit it to my jig . I took the plate and mounted it to my trans plate so I knew where to set the post for the new plate setup . once I knew where the post went I marked and drilled new holes and made a new post because my mounts were welded to the old post . once I had the holes drilled and post mounted in the jig I removed the trans post . I mounted the plate setup in my hardtail frame I built on the old setup and knew it was right and the motor and tranny and primary I have fit and lign up as it should . the plate droped right in place and lined up perfect those guys did a nice job on the plate. I then redesigned the clamps that hold the bottom tubes loosely based on their design because it had sportster distance built into it and I liked the way the clamps worked better than my cheep welded collars . I bought 4 of their 1 1/4 tube clamps and made a new set of spacers out of 1/2 inch by 2 1/2 inch plate I milled out spaces in the plate to fit the clamps so I could use them for big twin or sportster centers 2 inches off the jig to the bottom of the tube . I then cut some 1/8 inch plates to mount some set screws to hold the clamps and some spaces so I could make sure the clamps were all the way in the socket . I then spun a couple bungs on the lathe so I could use a plate on the bottom with a bolt to keep it tight to the jig and a small piece of angle iron got welded to one side on the bottom once I knew they were centered that way I can pull em out and put em back without even thinking about 80 measurements . once all this was done I droped the frame and plate back in the jig got everything squared up and made mounts for the plate to the post . I used a couple pieces angleiron marked and drilled 4 holes so I can pull the plate instead of the whole post to get the frame back out of the jig . everything went real well so I decided to make a jig plate for the foreward controls so when I do another frame it will be easier to place them at the right positionthe first two took me a couple hundred measurements . I didn't get that finished yet but this is the progress so far.
