this guy is really sharp. takes a good, proven product and figures out how to make it better. in this case, a new roller handle for my 550B, and a roller handle for my square deal B. the roller handle for the square deal is really neat. i like it 'cause it is more ergo for me and the cool factor is off the chart. the roller handle for the 550B is a huge improvement. i was having to bend over a few inches on each and every stroke. if you load 350 rounds an hour, that means you have to bend over 350 times in that hour. for an old timer like me, that can be an issue. with the new handle, i get 5 inches of less bending over, or i can pretty much stay upright. it is hard to 'splain, but it really is a big difference. the guy also sells all kinds of neat stuff, lighting for your presses and gunsafes, handles for other brands of presses, and all kinda gizmos to make your reloading 'more better'. check out his website www.inlinefabrication.com oh yeah, i ordered this past thursday, got the handles, today on monday. he was even quicker when i ordered my lighting for my presses. he also answers e-mails and returns phone calls, quickly. was goin' to post some pics, but they were too big, or something. but.....there are good pics on his website. other than doing business with the guy, and giving him my money, i have no other relationship with this guy or his company. i am getting nothing out of giving this glowing endorsement for great products and service. just want to give you guys a heads up on what is available.
