My modified feeder

PostBy: MURDOC1 On: Sun Oct 03, 2010 2:39 pm

Just wanted to put up some pics of my modified Alaska feeder assy... It used to be a tri-burner!!!

Still uses the Alaska gearmotor setup to work the carpet, but the rest is history...

This mod is simply bolted to the feeder assy. using 1/4-20 stainless button head socket cap screws and in no way interferes with the feeding of coal onto the carpet or other... Gearmotor is serviced by removing 6 bolts and the shelf that the motor housing is mounted to comes out the bottom of the whole assembly, walk away with it for servicing/oiling etc... The combustion blower is a dayton ball bearing unit and is bolted over the existing air inlet port... I used nut-serts set into the feeder chassis so only 1 wrench is needed to remove the blower and there is no need to remove the entire feeder from the stove or pop the grate to access nuts on the inside... All 100% serviceable from the outside... This unit performed flawless last winter and for this winter its getting a coaltrol setup and I will be running the ducting to bring outside air to the combustion blower... I am also thinking about building a custom hot air jacket, not sure yet on that one...

Lemme know what you guys think...

Thanks for the positive feedback!!!

If anyone wants this exact mod done to their stove I am willing to do it for you during the off-season... Send me your feeder assy. and I will mod it to mirror this one for a very reasonable price... I'll do it during the heating season also, but I don't imagine many of you would want to shut down for a week or two while I get it done for ya!!!

Looks good!
Is it my imagination, or is the mounting plate bending from the 4 attaching bolts? Would it be better to use thicker material for the mounting plate?

Are you talking about the mounting plate with the 4 studs with large spacers and stainless coupling nuts that hold the entire feeder chassis to the body of the stove??? If so, that is a part of the original tri-burner feeder assy from Alaska... I did not build this entire feeder, just modified the combustion air and gear motor mounting then attached it to the existing assy... All of my sheetmetal work was done using 11 gauge (1/8") and it is stoudt as all get out!!!

Yep, thats what I see. From the camera angle, it appears the 4 studs are bending that mounting plate. Must be an optional illusion :lol:

Nope, no optical illusion, you're seeing it right... There is a slight concave type deal goin' on there at each mounting stud, but believe me it is far better now with the 1" O.D. spacers spreading the force out than it was with the factory setup... Plus with the rope gasket between there it allows the plate to distort a bit to get the gasket seated well... Those coupling nuts aren't very tight at all, really just snugged up even... I agree on the materials, if I built that entire feeder chassis that particular mounting plate would be more like 3/16" plate to eliminate that... I like to over-build everything as you will see with my custom indoor 4 ton coal bin that is almost complete... I'll be posting pics of it real soon...

Thanks for the observation, you are correct Sir!!!
