Greetings All:

Some of you may recall that I designed and built CAM Locks a few months back. When I measured the CAM center to center distance it was just a crude measurement and the CAM locks worked fine but where not as tight of a fit as I would have liked.

So, my inspector used our CMM to accurately measure the CAM center to center distance off my cylinder heads.

So, I made a couple of minor tweaks to the design and the second generation of CAM Locks are coming soon.

Along with the sticky parts refinishing, we will be starting to offer Ferrari tools. The CAM Locks will be coming soon. We need to create a prototype to prove out the fit and after these will go into production and will be available for those that want to purchase them.

Details and pricing to come when available (guessing 4-8 weeks)

The first photos are the prototype made a few months back and the later images are the new generation to come.

Just a comment from a practical side. The cut outs look nice but to they really serve a purpose other than to look nice and increase machining time and cost? Actually, the tool might be easier to use if the cut outs weren't there as it would be easier to grip across the width. I.E. your finger would not interfere with the sprockets. Think about it. Your natural grip with the be to grip it side to side, not top to bottom. Also, looks like you are using pretty heavy gage steel so do you really need what looks to be about 1/4" (or more) from the OD of the holes for the locking pins to the edge of the tool? Seems that could be trimmed down almost by 1/2. Just thinking out loud. :)

John,

All good and valid points. However, doing design for many years I've learned there are always pros and cons. Yes, the cutouts are for looks to a degree (I don't make anything that does not look appealing :) ), but I also want good access to the center nuts and the degree pins. As for machining time, sure the cutouts do increase the time but you've never seen us remove material - sneeze and that material will vanish :) The reality is the cost will be driven by the low volume of sales and building enough of these per lot and inventory cost. I'm not making this stuff to get rich, I'm doing so because I believe the community needs some of these tools and I happen to have the experience and equipment to produce them.

And while the pins take 99% of the load, some small amount is taken by the friction of the clamp and part of the reason for some surface area. Could I reduce the size? Sure, but I don't see the need - these are not going on the space shuttle ;)

Oh no! Limited production. Do I smell a Ferrari tax? :)


I'm sure it will be a nice tool even if you ignore my suggestions. :)


[edit] I didn't see the nice rounded corners. More machining. But at least it won't hurt as much when I drop one on my toes.

And to other reading this. Dave know I'm just goofin' on him. Seriously, it will be a nice tool.

Your suggestions are good John but you have been overruled ;)

Story of my wife. I mean life. No, it's my wife. :)

Ferrari tax? Perhaps - yet to be determined. I was going to make these from stainless steel but I talked myself off that ledge :) They will get black oxide though....


Titanium!

Just make sure the ones i asked for dont get sticky in a few years. Ha ha. Also since you did use your right side of the brain (artistic) would you please number them so i could have 2 of ...... I am sure the artist always keeps number 1. This way mine will be worth more money someday. Did i mention they look awesome!!!!

cam locks

Dave ,
I checked out those cam locks, and I think they look great. And they should serve their function well I might add. My only question is; in order to install the tool with a "worn" belt, will the pins line up, or will one need to tweak each cam into the tooth? Thank you. -John

Hi John,

I'm going to add more info to our website soon as there is a bit of confusion and misunderstanding on how these function.

First, I designed these primarily to hold the cam pulleys in order to loosten and tighten the cam pulleys. In order for these to fit, the relationship of each cam pulleys to the other is specific and critical. Based on belt slack or tension, it may be required to rotate one cam very slightly with relation to the other to get the tool engaged.

For a "lock and swap" of belts, please note the engine does not need to be at TDC. Orient the cam pulleys per the image below, install the tool to lock the cams, lock the crank, remove and replace belts. Note, because of cam timing, you may only be able to lock one bank at a time.

The other option is to flip the main body and not engage the pins and just use the tool as a pure clamp. This will not resist torque on the bolts this way though.

Feel free to contact me if you have other questions. Thank you.
