LMTV Caterpillar Diesel Fuel Additives

well it is machining it... any knucklehead can remove metal, the skill and "machining" comes in building the fixture to hold and move the cutter in the proper relationship to the workpiece. have learned some interesting ways to machine and fit, working with old slow speed diesels. All handwork, all fairly simple and relatively precise. not especially fast though... guide rails and draw file can be very precise, you just spend a bit of time building the jig(baseplate and studs with nuts to hold the guide rails alongside the workpiece), measuring and adjusting the rails for each successive cut/depth adjustment. you can even use a cross rail on the guide rails to map the surface irregularities. not rocket surgery, you just need to think your way thru, same as you would using a mill...

Funny, People always ask me can I teach them and my response is always I can teach you how to operate the machine….I can not teach you how to be creative.

Exactly!

Lots of old school, old world methods available. Could scrape it the way lathe and mill beds were done 100 years ago. Or spend hours with glass and 120 grit fabric backed abrasive sheets (it goes up in grit as you wear it down). Actually use this method on aluminum cylinder heads all the time and get excellent results - have tested the surface RA with a profilometer.

Machine shop that does cylinder heads will likely use a CBN cutter. But a large belt sander could also work. Finish doesn't have to be especially good in this application. Not an MLS head gasket surface.

For the record, I first tried the 120 grit on a glass plate and it took forever to make appreciable progress. Could you make it work? Yes. I'm just not sure I'll be living that long.

I been driving 150 miles today hitting all the automotive machine shops 5 different places and no one would do it. How did you end up doing it Chris?

Small local auto parts store that has a machine shop. They have done two of them now. Chris knows the owner.

I just heard that story from John

Used to have a real good machine shop here locally, then he retired and no one ever picked up the business. haven't had to search for one in a while... Joys of being rural...

I am blessed with a "real" parts store quite literally down the hill from my house and the owner is a neighbor. I have a few vehicles which fall nicely into their parts demographic and use them exclusively to try to make sure they stay in business. Great crew and resource.

If they weren't able, next up were cylinder head refinishers. We have at least one specialist shop nearby and probably a few others in the metro area.

Worst comes to worst, ship it out here and I'll have them cut it... I'd be happy to get that to happen but I doubt that's worth it time-wise.

Thanks I’m going to pull it apart today and see how bad it is or isn’t.
