I'm working on a trigger wheel setup for my wife's D16Y8 (yes, Honda) and was planning on ordering some parts from eMachine shop. I used their software to make the part, got the quote, and it's like $105 for 1 part, $110 for 2 parts, $113 for 3... you get the idea... all set-up cost. Anyone interested in an Electromotive TEC trigger for kit for D-series Honda, or Opel, or whatever?- not looking to make any profit, just share costs.

This was for a laser cut trigger wheel from .19" 1040 steel... I'm working on redesigning to make it work on thinner material or maybe mill cut to get the cost down a little- of course if any of you need something cut from the same material I can put it in the same g-code program and the cost per piece goes roughly in half, in 3rds for the 3rd part, etc.... any takers? Anyone want some fancy brackets, trigger wheels, etc?

BETTER YET- any of you guys got a CNC that could be hired out in exchange for materials, homemade wine, and an generous helping of thankyous?!?

I also need to make a plastic housing for this thing that may be machined out of a big block of ABS or possibly SLS/SLA/FDM- rapid prototype... news as it develops- still working on the design on that one though.

Think I need my own CNC!

I've got the design about done in eMachineShop, and all together the bill is like $550 with aluminum housings and fancy brackets and what-not. Crap that is a lot of freakin' money for putting parts together that were more or less free... think I'm going to have to make some of this stuff myself. Might still go with the laser cut for the trigger wheel.

Got me to thinking though... for a couple grand I could get my OWN tabletop CNC and make all the custom parts I want. However, my CNC experience is limited to programming g-code on a late 80's vintage CNC mill roughly the size of a volkswagen. Too big for my overstuffed garage. There's a lot of cool table top CNC's out there now though... like check this one out:

There's also a DynaMyte 2400 that looks like a real legit piece of equipment... but I know just about nothing about these things.

Any machinists wanna put in their $.02?

BTW- Dave - send me drawings of what you're wanting to do and I can prolly get it into eMachineShop for you while the boss isn't looking ;-)

just send drawings to sporqster at msn.com

how many teeth are on the Petronix? The TEC II I'm using wants to see 57 blips and a long blip... 60-2 tooth wheel. So basically I'm making a wheel to cater to what that computer wants to see.

That was plan A until I realized that I would still have to make something to attach this to the shaft, and I can't screw it up- the out of round tolerance on this thing is .001"... I don't trust myself to manually drill holes to within a .001:.

From what I recall, Electromotive charges some $50 or so for these too, and I would still have to make the housing so that I can mount the pickup at the prescribed .01" away.

Sporqster,

Are you still considering an emachineshop order, I have a custom trigger wheel that I need made too, for a Ford EDIS/Megasquirt II combination going on the V6 conversion.

Let me know and I'll get the file to you so we can get a quote, I would like to get a few of them.

Thanks,

Sure Nathan, I've not got too much to do at work today- shoot me dwg's or dxf's or something to scale and I'll put it on the emachine shop file. I'll send you back the file and either of us can place the order.

I'm still going to do the trigger wheel laser cut, but I'm leaning towards buying my own small CNC for the housing.... There's been a lot of nice looking table top, 110V CNC's going for under 2k... might make a nice addition to the garage, and who knows, maybe I can make it pay for itself.

BTW- bob- about the whole aluminum housing thing... I'm sticking this on a Honda, and I've got a *FREE* 8-cyl TEC. Not a serious performance application here... mostly screwing around with 'found' parts. Since I pretty much have to put the trigger wheel in place of the dizzy rotor. (the whole 4 bangs per revolution thing) I need to keep the stock trigger also as to not disturb operation of the stock tach. I could probably rig something up drilling a hole in the distributer cap and mounting a pickup out there... but a big ol' block of machined aluminum bolted to the side of the distributer has so much more 'bling' factor!
