Small V8

[jpeter]

Did you heat treat the aluminum after you poured it?

No heat treat cuz I didn't know how. I had a foundry in my shop and all the students made castings. We machined a few along the way. Used mostly scrap siding for the melt. Before prices skyed people threw that stuff away or give it to me. Anyway, I got pretty good a making a casting. It was the metallurgy, shrink and things like that that I never got very good at. We had no facility for making cores either which I think would be important for something like what you are making. It'll be fun to see the results.

I've had opportunities along the way to visit foundries and see results of work done by folks who actually know how to ram up a mold and get all the other things right. It just makes me realize how little I know about casting aluminum.

I use 6061 for the melt and after a week or so sitting around, It is hard as heck again. I'll bring the pattern to the next meeting. Will you be back by then.

I'm back and I'll be looking forward to seeing it. It looks great. Did you cnc the curves. If not how'd you come up with the coordinates for the curves. I suppose a spread sheet would lay them or or maybe a cad program. I'm curious.

CamBam did the whole thing for me. I just opened the file, defined the stock, told it what tool and it knows where.

Cool. Never heard of it.

Scratch motor mounts off the list.

Couldn't find any 1/2 X 1/2 X 1/8 inch aluminum angle so i had to make some.

Then the back was cut off to form the tabs.

Used a radius cutter to round over the nose of the tabs.

Spotted, drilled, and counterbored the holes to bolt it to the motor.

Rotated the piece forward and drilled the tabs.

Again the back was milled out of it.

And we have the mount complete. I now have to match drill the oil pan and bolt them on.

Looking great Steve! When ya going to mount it up? ;D

Great build bud, Are you going to publish this...( Sorry probably been asked...probably by me too...my brain is mush today)

Are you going to publish this.

Thanks Steamer!! I just finished mounting them.

What do you mean by publish? Make plans available?

 

[stevehuckss396]

Not alot of progress but progress none the less. The oil pan is offically done. I drilled the holes for the motor mounts. I also added a hole with a pipe plug to allow for checking the oil level. Now both of the boys are standing proudly on there legs. I mocked one up just to get a feel for how big they will be. SMALL!!

Thanks Steamer!! I just finished mounting them.

YES! ;D

[stevehuckss396]

YES! ;D

I will make drawings if it kills me.

Well done Steve
Its my ambition to work up to a V8.
but Im not there yet either in skill or tools

Looking good, Steve. I like your design for the engine supports.

Chuck

 

[stevehuckss396]

Thanks men.

That is the same support system I used for the Peewee.

Hi Steve, I've been watching your build for a while now and it's been very impressive. Something tells me it's going to be louder at the Names show this year. Keep up the good work, Dave

 

[stevehuckss396]

Something tells me it's going to be louder at the Names show this year.

That would be nice but i'm not sure I will have them ready by then. Still alot to do!

Thanks Dave!

 

[deere_x475guy]

Awesome work as always Steve...I am looking forward to seeing you at N.A.M.E.S this year...and take a look at the twins.

 

[steamer]

I will make drawings if it kills me.

Though I admire your dedication...it would kinda defeat the purpose wouldn't it? ;D
