I spent a lot of hours honing valve guides for 7MM valves. That was at a shop I worked for they did cylinder heads for Comp Eliminator engines. Thanks Don
This was an item I purchased specifically for motorcycle cylinder heads, not only for the guides but for the guide holes in the head itself as there is always damage from the old guides being removed. Having a clean, true hole to install new guides is most important in air cooled engines that run much hotter than liquid cooled and even hotter on low octane fuel. Otherwise there would be poor heat transfer from the hot valves to the cylinder head causing all kinds of havoc and short service life. This stuff is in Pratt & Whitney aircraft engine service manuals using P&W special honing tools and guide and seat pullers. I replicated those methods of installing seats and guides into clean holes with the correct surface finish, and never had a valve stick but they still can float!
I love those old adds. I had a stack of old Post and Life magazines I found in an abandoned farmhouse when I was working on a pipeline in the oilfield. Later my boss wanted to take them home with him so I let him. He stole them from me. "Shinola Shoe polish 5 cents per can. Gillette Red Razor blades , Adds of Bell Telephone inventing sonar for the submarines in WWII. And the list goes on and on. I have some racks of old Hot Rod magazines in storage for my son to enjoy when I am gone. I also have a collection of old calendars.
Thanks for sharing your knowledge Don! I just found a pair of Honalls I'll use on aircooled VW valve guides and maybe lifter bore bushings too. Would love to see more on how to use these little wonders!
wow, I did not know they could remove parts of your videos like the ads you mention...... that is just wrong.....I love those vintage ads you post....... maybe you need more pin up gals ? or B-25's ? arrrrr...... how dare they, you know, I have been finding some of my comments not showing on some channels.... but no mention of why they are not there ???? Have a wonderful day Don, Paulie
Cool tool. I got one years ago when I rebuilt my old Cummins dodge engine. I machined 24 bronze guides and changed up the upper ends. When pushed in, the valves are too tight to move. Perfect. Use this tool to remove a whisker at a time. Until the valves are just perfect.
I was surprised how well the Honall worked, like you mentioned how a pressed in part will squeeze, that is not a good job for a reamer because the cut is uneven, tears the metal and dulls the reamer.
I have some odds and ends Amco small hone kits but they are intended for automotive. The are some other brands of honing tools but I am only familiar with Sunnen. Sometimes the Sunnen honing tools are reasonably priced, but right now the used prices seem to be very high. One Sunnen advantage for me was the tech help would know what I needed before I finished telling them the problem.
Chloe checking out the action in the front yard.......hope your day goes fantastic Don, Paul in Florida
Looks good!
Those old add's are great ! Lol , a Fitter & Turner knows what those things are for ! Cheers 👍
Yes they are! I stole them from Short Pants!

The views on many subjects is declining, it appears the platform is out for all it can get.

You're welcome
Looks like Chloe has had a bisket or two. She is surely not starved.
She is going to boot camp!
Dee I have looked for some small hones but all I find are the spring loaded brake hones and such. I would love to have some small diameter ones.
