Here’s a few thoughts;

1) Buy yourself ball or needle bearing to go onto the cutter head shaft (between the pulley and the journal bearing) to keep the chain off the cutter head shaft. The chain can ride on the bearing directly if you’ve got some spacers to position it under the chain, or you can let the the chain position the bearing using a grooved OD sleeve on the bearing (bearing just floats on the shaft).

2) Add a jack shaft to change the chain speed. You can mount up a couple sprockets side-by-side. The ratio of those sprockets changes the chain speed. This idea (like your own) has no accident protection IE; if you hit something, there is no slippage.

3) For added protection, consider driving the jack shaft with a pulley & a cheap belt. Example; a 2” x 3/8 V-belt pulley drives a 4” pulley (diecast zinc from TSC pulleys + belt for under $20 total).
