Nice chunk of 1/2" maple bolted into the mill, what could it become?

Motor mounts for a new Slow Rat.

Engine mounts and gear blocks for me.

A wood carving of Halle Berry! Hey, I was waiting for someone to mention that, and no one did.

Wow, Milt, it is amazing that no one came up with that before you! These guys must be kinda slow...........

Who's Halle Berry? Fly CL?

My guess is that there will be a step cut in the maple plank, and then it will be sliced into engine bearers on a table saw. Is there a prize? What did I win?

No prize, but close. This is going to be a crutch for a stunt plane. I am machining the cructch as a one piece unit. So far I have the engine mounting holes drilled and a pocket milled for the tank area.

Sheesh, Mike, how far you've sunk! That used to be the way you buiklt the Slow Rat mounts. But for STUNT?

Last time there was a nice chunk of maple in my mill it was to make a large spoon for cooking.

The next night I was watching "Alone in the Wilderness" and the guy knocked out a big spoon from fresh-cut spruce, primarily using a double-bitted felling ax.

I am soooo hung up on power tools...

out of the mill now, will flip over and mill pockets for blind nuts in the other side. About 80 percent of the plank is in my shop vac now. I make my living running cnc mills and lathes, then sometimes i come home and make parts for toy airplanes on a toy cnc mill.....

Mike,

Nice work! I could use something built like that. Would uou like to mill something for me, from a full scale drawing?

Hey Mike:
What advantages do you see in making motor crutch from a solid piece of maple stock ?

Lauri Malila · « **Reply #14 on:** January 03, 2012, 02:15:07 PM »

I was wondering the same. The 2 "spacers" that hold the bearers apart don't come even close of the strenght and stability that for example cross grain balsa gives.
Plust that you loose material worth at least one pair of engine bearers.
But of course it's COOL. Sometimes that is enough. L

Probably not really that much. Solid or built up it would go into my mill anyway to drill the motor mount holes, and mill the tank compartment area. I use plastic tanks, and they need a recess to get the tank on centerline with the motor. I left a .05 thick floor on the bottom of the mounts. Kind of nice to have a one piece unit that is both flat and straight. As far as being wasteful of material, this little chunk of maple is cheap in comparison with the rest of the plane. I have made several slow rat front ends in this fashion. and for that application it makes a really solid front end. I wanted to try this for a stunt plane and see how it went.

I think it's cool, Mike.

Yeah, but leaving the web in gives it an order of magnitude increase in twist and compressive strength. Just gluing maple to maple is a quite iffy proposition. Plus then you have to glue a ply web to get the same thing.

Wish I had Mike's "toy" cnc mill!

This summer I had a 9000 pound casting on the mill at work. When I secure the parts to the table, I am standing on the table. I can call a mill that I can set on my kitchen table a toy if I want to!

Nice work and great idea Mike! What brand/model mini-mill is that ?
