We've decided to use our HS Tarm 502 to burn coal this year. It's been working fine up until something used for the shaker grate broke. The name of this part is the shaker handle shaft. It's the shaft where the shaker handle bolts to on one end, and the other end engages with the first shaker grate. One of the ears on the handle end broke off.
Also, if you burnt coal and happen to have the 3-pience coal baffle apparatus, I would also be very interested in that as well. You can contact me directly via email at jbstouffer @ yahoo.com.
Thanks,
