I'm going to plug this into my cnc mill at home after I finish the engraved oil catch can.. may as well sell em to those who want one (after i've made and tested)

the degree marks are the cam degrees - not crank

so the 13 degree retard people like to do is 6.5 cam degrees

this is really just a preliminary design till I get some more measurements
I'll be redesigning it to allow adjusting screws to apply force to the cams to adjust them with the crank sitting at TDC.

The CNC at home? NICE Man what I could do wil a CNC at home
Cool project.

redesigned - there is now a 3/4" hex to put a wrench on to adjust the cam timing
its currently adjustable up to 12 degrees advance or retard.. (24 crank degrees each direction)

I would definately be interested in one of those; that would be sweet!

hello Nice job, if possible I also may be interested in that tool too. thanks Norm from www.normsfiberglass.com ph. 574-255-7843

looks like interest is growing quickly so this will take priority over the engraved oil catch can.. I'll try to get the prototype built asap

This would be a hot seller on 60* V-6. Changing the cam timing is a pain in the but the common way. I'd be very interested in this.

Yeah, you should definatly post this over on 60* V6. I'd take one if I had a 3.4TDC...

Looks good keep us posted

ill take one too, id like to be able to adjust my cams at home and that is one hell of a nice hold down tool! Thumbs up to you!

my website is up now - http://www.viscoustech.com/

I have it setup so people CAN'T pay till i have the items in hand to ship..

ok finally - the RSX shifters are done - the cam timing tool is next to get prototyped - i'll start this week

a sample of my work for those wondering

Looks like you do some nice work.

There is very large interest in this over at 60*V6, I say go for it!

I'll be wanting one.

alright I got the measurements off the engine today and modeled it up -

this is now the latest design - its been priced for production and can be ready in 1 month
I may start a pre-buy to get these done asap if I can get people interested at 75$ with free shipping

I will be milling the prototype next week for a test fitting before ordering a production run.

I'm in, $75 shipped, you have a PM.

Guess I'll be the first to try it out, your reputation rides on me

prototyping begins

one component after a quick iriditing bath for corrosion inhibiting

lookin good!

i'd be in too. response to what you said at the top. yep, cams move at 1/2 speed of the crank.
1 suggestion, since the 6.5 will be the most popular use of your tool, put a 6.5 specific mark on it.

[This message has been edited by dohcfiend (edited 01-05-2005).]

Cool! Nice work and good thinking. I would go crazy with a cnc machine if I had one

I agree.

problem is .5 degrees is about the width of the actual mark itself

edit: hmm ok i may have an idea for a different location for the timing marks.. after I make the main peice i'll play around with a pencil

[This message has been edited by Kohburn (edited 01-05-2005).]

I am in too. Let me know the details.

I will take one when they become available. Do you need payment now? Let me know. Thanks.

no payments yet - not accepting money for pre-orders till i have tested the function of the prototype.. I'll update this thread with all the info as it goes along - sittign here watching the mill run as i type so I may be testing this weekend..

milling done (except timing marks) - next to test how well it works

That is SWEET!!

Bump

any tips for getting the cam pulley bolt lose? I'm still waiting on my aircrompressor from harbor freight so i can use an impact gun on it - bolts are tight turning them is turning over the engine

maybe im just unfamiliar with the 3.4 but how does this tool work?

I made the cam holding tool, stil turned. I nthe end I used the impact gun. 30 seconds and they were off versus 2 days of messing around with the 'correct' tools.

the cam pulleys on the 3.4 TDC are not keyed.. they are essentially just held on by a bolt.. so to time the cams you have to set the crank at top dead center and use a tool that holds a flatspot on the cams in place then tighten the bolts again.. this tool allows you to set degrees of advance or retard before tightening that bolt.

just a little update with something prettier after engraving and painting (the production version would be anodized not painted)
I'm currently figuring out how to flow a bright pigment into the engraved degree markes..

Fantastic work. I have always had to use the impact on the cam bolts. It is the easiest way.

Have you used the tool yet? I am anxious to get one of these. Thanks for all the great work.

Matt

Unless i get around to it sonner it will be getting tested next weekend, and pending any revisions would be available for sale a month after
(after a successful testing i'll be accepting pre-buy orders, but not untill I know for sure the design doesn't need changes)

count me in for one

Alright guys - I decided to relocate the timing marks to the top to make it easier to see while installed
the production run has been ordered and they are up for pre-buy sale at www.viscoustech.com

estimated shipping date is the first weekend of march

[This message has been edited by Kohburn (edited 03-25-2005).]

bought mine thanks... any idea when they will be ready?
