I have a set of cast iron BHJ FE 352-428 Honing Plates that I no longer need (my machinist also has a set) I would like to sell them for $100 plus shipping. I thought I should post here before eBay or the other forums. Any Interest? They are still in BHJ shipping boxes.

I'll take those plates, Bill! I'll send you an email - Jay
-
Done! I'll send them this week.
-
Jay, sorry for the delay, its been almost as crazy here as it has been on your end. I'm shipping toda.

Any chance I can see a picture of these plates.
The thickness and material would be great also.
I just had a look at the cost of them new. Yikes! Smoking deal there Jay.
I have a big cunck of aluminum plate that I have been thinking I need to whittle
some plates out of.
I'm just getting my big First 5HP 40 Spindle mill back out of storage and going to set it up in my new
shed. Man I have missed my big drill.
Thanks
Howie
Mod: A pic of a couple of tools I was able to save after a few rough spots. ;D

Nice looking machine tools there, Howie. I'll try to get a picture or two of the plates and post them in the next couple days. The plates are steel and they are HEAVY; shipping was about $80...
-
Here's some pictures of those plates, Howie. They are 1.75" thick, but I don't know what the material is, other than its some kind of steel. One of the plates has through-holes so it can be bolted onto a block for honing operations, and the other has threaded holes so that it can be bolted to a head for valve job work. I agree that they were a pretty good deal, and have to thank Bill for selling them to me at that price and getting then shipped out here. Shipping those heavy things was $75 alone LOL!

Thanks Jay.
They have always made me think about different load factors comparing materials, bolts v studs, gaskets.
ie: Is the distortion different between iron, steel and aluminum?
Does the distortion change when you have an actual head vs the honing plate?
How much does the gasket play in the distortion and would different materials change the numbers again?
Almost a chapter in a book. LOL
Thanks again for the time.

to the blue paint and lettering except mine says SUNNEN. Everything from Studs to Bolts alters the effect on the walls but realistically so does hot water/heat in the block. One things certain just bolt on a set of heads and measure the bores for a shock. Gaskets same as will be used are supposed to be installed when honing. Obviously a real head will distort itself more then those masses of iron
-
Scotia, here's a neat video (start at 1:20 if you like) of how a deck plate, studs, etc. affects a cylinder bore. Most high end shops indicate that literally anything that changes (studs to bolts, one type of head gasket to another, etc.) can and will affect the bore...meaning don't do it. As mentioned, really high end engines not only get plate honed with the exact components installed and torqued that will be used in the build but hot water at the expected operational temperature is circulated through block during honing to achieve that perfect seal.

I've seen this done but I've never actually seen a Serdi-machined cylinder head with a plate as the NASCAR folks and others do. How does the tooling get around the massive thickness of the block honing plate? Do they use a plate with large reliefs to allow access to the valve seats? Anyone know or have a pic of head being done this way.

Are these plates made from cast iron or steel? And how thick are they? I been thinking of making a set for myself to save the full cost of buying a set. It`s not a big deal for me to make them as I have a fab shop business. Garry
-
As noted above, they all seem to be about 1.75" thick. The ones I've seen are steel plate but I guess they could be made out of cast iron. And sure making a set for yourself would be kinda' neat but if one adds up machining time, unless it's free, and the $ for material stock, looking around for a used set might be easier.
-
I will probably have Willie make a set up for my shop in aluminum.
I suspect that the "trick" setup will be to bolt a real head onto a block & measure the distortion from below - and then find a torque value that mirrors that distortion with the plate. In the past we used the BHJ iron plates with a stack of washers/shims to mimic fastener heights, along with the proper gaskets. Just seems that we should also be using the same material as well...
