Ironhead XL 79-81 weld on hardtail frame tech

Justin at DP customs sent me photos of his work. http://dpcustomcycles.com/Welcome.html
1- cut frame duh !
2- make slug inserts for extra strength at the top and plug weld them last.
3- clamp your frame down to your table level prior to setting the rear tail level.
4- use bolts at the bottom to help align the tail section these can be left in or removed later after welding.
5- tack weld each end and re check it for alignment and level
6- Finish welding. Recommend using some all thread between the axle plates using 4 nuts to hold the rear width in place until all welds have cooled.
