That's just hot. All things that i would never normally like, but somehow put together in a way that just looks the business.

[Mr. JLT]

I have been working on making a few throttle body flanges for my SRI so I can move the TB a little futher away from the radiator fans-about half way done with one so far.This one will bolt directly to the SRI-I machined down all 4 sides to get a true square, drilled all 4 6mm holes and working on machining out the center. Hope to have one done this weekend

Great work dude. Just how i'd go about it.

Nice little miller

Are you working both feeds by hand Jay?

[Preen59]

Looks like a little CNC mill to me..

Now tell me how the heck you picked that? Haha

All i noticed was the NT30 taper, = smaller miller. Hafco or something?

Jay has skillz!

The job has no visible marking out and that hole is way too smooth to have been done by hand. My guess is that's a roughing cut at (what i would do) ~0.3mm less than the finish diameter, followed by a finishing pass, slow the feed down, up the RPM, some coolant to keep the cutter lubed up and the cutter/material cool (also improves the finish 10 fold on aluminium) climb milling to achieve the best finish.

Sorry for the thread highjack there Jay.

Ta, I'm sure we can have some good discussions elsewhere

Yeah sorry Jay! Top work.

[Mr. JLT]

Yes both the Y and X are ran by hand, I am learning from John my neighbor--Haha sorry no CNC machine-- the only one in town is townville laser cutting center and they dont like to cut aluminium cause they say it can burn there mirrors out if the excess metal is not jet cleared fast enough. So John has offered me his equipment to learn on.

[Mr. JLT]

I was running the Y axis and John was running the X axis. we where cutting a .5mm. It was a climbing cut so far and the 1st cut we have made so far- it feels good at this point I may not do a finishing pass or I may break out the sand paper or bead blast it for a primo finish

Interesting. I did notice that the hole was slightly eccentric to the slot, but i just figured you were using a different centre. That's very neat if you were doing it by hand i must say. I probably would have set it up in a 4 jaw chuck on the lathe and bored it out if that is the case.

either that or chucked a rotary table on the mill!!!

good work Jay

[Mr. JLT]

Almost done with 1 of the throttle body flanges, I think im gona hit the corners up with a belt sander. I'll start the other one this week so I can get the Sri extension done and welded up.

[Preen59]

Looks good Jay! What grade is that out of curiousity? I see "65" on it so i'm guessing it's hardened to T651?

I'll have to look on the other pc but i thought it was T 6061
