ND, it depends on what you are set up to work with. Do you have a flat bending jig? You mentioned you have access to a metal shearer. So I assume you would cut the flat with holes up and reweld it. This is an option, but if you haven't done much welding, it actually might be a real PITA. Not to mention that your cuts and heights would need to be fairly accurate. If you're not cut out for the work, the ACE might be a good choice. It too involves some work, but mainly only drilling and filing. That is what most of us started with. It wasn't until recently that we had the capability of bending flats into real receviers. By the way, as far as I know the "Joeken" flats are actually Tapco flats. I don't know how much they go for there but you can buy them from Tapco for around $20 or less. I think they might have some ones with a little rust on them for around $12. I would be very careful dealing with Joeken. Good luck. Sounds like you've got a nice kit to work with. Did you buy it recently?
