The spike elements are concrete nails which have lengthwise striations . There is little tendency to side-thrust material. We also experimented with addition of a chopper element such as ah shown in its larger TMC cousin and that definitely required a flywheel. but as much of the action is not a continuous rotation in one direction but trashier an osi collating motion with heavier material the flywheel adds little <br><div><div>On Apr 15, 2014, at 9:13 AM, Crispin Pembert-Pigott wrote:</div><br class="Apple-interchange-newline"><span class="Apple-style-span" style="border-collapse: separate; font-family: Verdana; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div lang="EN-CA" link="blue" vlink="purple"><div class="WordSection1" style="page: WordSection1; "><div style="margin-top: 0mm; margin-right: 0mm; margin-bottom: 0.0001pt; margin-left: 0mm; font-size: 12pt; font-family: 'Times New Roman', serif; "><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125); ">Dear Richard<o:p></o:p></span></div><div style="margin-top: 0mm; margin-right: 0mm; margin-bottom: 0.0001pt; margin-left: 0mm; font-size: 12pt; font-family: 'Times New Roman', serif; "><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125); "><o:p> </o:p></span></div><div style="margin-top: 0mm; margin-right: 0mm; margin-bottom: 0.0001pt; margin-left: 0mm; font-size: 12pt; font-family: 'Times New Roman', serif; "><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125); ">I am surprised to see the working bits of the mini TMC have a spiral from one side to the other for the reason that it creates a constant thrust in one direction.
