Real Fiero Tech

Picked up a mill and lathe of my own awhile back. Benchtop stuff makes for a limited work envelope, but they’re still pretty handy.

Yeah, just the inlet of it though. the stock tb will take a 3400 blade.

I think the 3400 is 56mm. Easy upgrade

Wasn’t too bad. Opening the neck up was a little more involved.

I think the point of the auto modification hobby is to fabricate stuff.

Buying off-the-shelf parts and bolting them on is boring.

I like grinding my own HSS tools; I like being able to make/modify a tool to fit the situation at hand, without any leadtime.

So I dynoed a 56-7 th from Darrel morse years ago on a stock upper. Did a before and after. Worth about 3-4 hp in my combo. 2.8

Hand grinding can be pretty rewarding. I still do it when I need an extra sharp edge or to get in a weird spot.

Every little bit, right? I didn’t try it by itself, but it made a difference in combination with the manifold. I’m not going to guess on hp, but I did have to add fuel all over the table to maintain afr

Not the prettiest thing and probably not the best way to do it, but the idea was to use what I had on hand and not actually buy any material.

AND.

It’s not like you can see it when screwed in place.

If you have a stock intake also, do a test on how much volume you added.

I just have the one. I was watching a couple on ebay in case things went wrong.

I need to get some stuff like this... I have to many things I would use it for! I also still need to finish figuring out the odds and ends of the pile of 3d printer parts I bought last year...

They're great to have for smaller stuff that can't be easily bought. And if I need more swing, I can usually find somebody to help me out

That's a huge machine! I'm hoping to start building my workshop middle of next year. I need to keep my eyes out for a few key parts to build a 3 phase converter, and maybe a step up transformer. I want to end up with a decent sized mill and lathe, among a long list of other stuff...

I'm a cnc service guy. I do installs, repairs, robot interfaces, etc.

Depending on what you get, it may be easier and long term economical to use a VFD to make your 3-phase (for single motor stuff anyway)

my idea, is that I'll build an idler motor converter, and use it to generate the third phase. 3 phase equipment is typically easier/cheaper to pick up at auctions, and as machines get added to the shop, the expense of VFD's goes up, but they have other advantages as well. I have time to think about it.
