I've been busy for the past few weeks. I've redesigned the upper sheets adjuster for the primary belt:
I designed my original upper adjuster so that it could easily be added to adjustable sheets that I'd already sold that had no screw adjuster. I designed an upper plate that set on top of the sheets in a 3/4" notch that could be cut with a common bench grinder. The problem with that design was that the plate popped up on the right side when you tightened the left adjuster. Think teeter totter and you'll have the right idea. This new adjuster plate fits through a slot laser cut into the sheets. It can't pop up. And now that the right side is held down the right adjuster bolt can be used for what it really is: a belt tracking adjuster. You can now level the jackshaft and adjust the tracking of the belt so it neither walks off of the end or rubs the flange. If you've ever used a belt sander you know that being able to adjust the belt tracking is important. This is a simple mod with a big payoff.
I've also made some changes to the bottom sheets and adjuster in response to The Great Hardware Crisis of 2014. On the 100mm BB sheets I've added a second adjuster bolt as suggested:
This not only makes absolutely certain that the lower slide is level in it's travel, it splits the load of tensioning between two adjusters. I'm hoping that this will help users adjust the secondary chain without too much frustration.
I'm still fussing with slide hardware trying to come up with the best solution. Right now I'm using M5 hex nuts with nylock nuts. The next time I have a bunch of lower sheets laser cut I'm going to redesign everything to use larger bolts and I plan to upgrade to Grade 8. People have asked why I've mixed metric and SAE hardware. I try to stay to an international metric standard wherever possible. Since I live in the USA where SAE was the sole standard for many years there are still a lot more choices in hardware in SAE. Metric is still looked on as "special" hardware here. Some metric bolts are hard to get and some just can't be had.
Other plans on the horizon are switching from painting steel parts to black oxide coating them, making new design pant rings and belt guards out of aluminum instead of steel to reduce the weight of those parts by 2/3, and designing a far better upper frame mount to reduce the inherited GNG upper mount flex. I'm finishing the first big block kit right now. It will have the first new upper mount to help deal with all of the torque of the big motor.
I'm nearly done with the first big block kit for Walter S and have motors, long jackshafts and sheets for six more. I'm also nearly done with a 100mm stretch small block kit for Andrew F. Along with that I have an order for Stephen F in Switzerland that includes five small block kits with a wide range of 68mm and 73mm regular and stretch BB brackets. The orders I'm working on right now are about 4 months old. A lot of orders came in at this time so it's taking time to dig through them.
I've been corresponding with many of you pretty regularly by e-mail. In addition to his constant presence on this thread Emaayan has sent me over 240 e-mails, most of which I responded to. I do my best to respond to all of you, to take care of all of you, and to deal with the challenges of what I've taken on as best I can. Thanks to all of my friends here who've been so supportive and helped me keep it together.
