CNC CMB THROTTLE ARMS

[Douglas P Shepherd]

I am making Throttle arms for the cmb 67's greenheads

They are CNC complete out of 6061T6 aluminum and are ready to mount with set screws $10.00 per arm

if you need any contact [email protected]

Preston Hall also makes the replacement CMB throttle arms & they are race proven.

It's all good!

Too bad CMB doesn't care to make them right. They've been breaking for years and CMB knows this well.

CMB arms are also CNC machined from 6061-T6. It's wouldn't cost them an extra 50 cents to add a radius and use better aluminum (6061-T6 isn't the best for this application). They just prefer to make them with a sharp corner so they'll break and they can sell you another one. :angry:

Problem is they could care less if your carb arm breaks in your last heat to a US-1, National Champion or World Champion victory. :angry:

You are very much right on the aluminum and the radius Andy,One tool and 15 sec of run time per part would save alot here. I have been heat treating the ones I am using and have not seen any breakage. But there are alot materials that would work better here.
