John, when I referred to supply chain issues, they affect all manufacturers, including Matt and Comnoz . Jim couldn’t get parts for his Cnc machine and it was only after xmas that matt took over production of the headsteady ,which has been out of production for about a year. Matt also had to wait for parts to finish the ISOs. Once he got it sorted,then the usps thing stuffed things up again. I think if you look at Matts site you will see a lot of his parts are out of stock, mainly because of supply chain issues. Even rgm and andover suffer from that with some products. The usps issue was created by usps supposedly withdrawing the Australian route to use aircraft on internal u.s routes. If you go back and read gortnippers earlier post ,you may get an insite into usps. I have continued to receive parts from India , u.k and basically anywhere that doesn’t use usps. Although that( hopefully ) is about to change
