Here is an interesting comparison of cranks.

Left to right

'35 Pierce Arrow stroked 8. Notice the cast counterweights

'33 Pierce Arrow 8, notice the heavy bolted and welded
counterweights

'38 Packard Twelve. Counterweights but precisely attached
and balanced. Beautiful piece of machine work. Shorter
than the Pierce 8's but 100 cubic inches bigger

'71 Morgan +8 (aluminum Buick/Rover 215 V8) Impressed by
how short and compact it is. It is almost as short as
the 4 cylinder next to it

'65 Morgan +4 (Triumph TR3/4)

Lightly touched up the valve seats.

Machined a bushing to allow me the ability to cut them without having to put the guides back in and use a pilot that I already had.

Took less than a turn to get them bright.

I will lap and set the clearance on the valves once the guides are in, but you have to have the silencer blocks installed to do that

Twelve water jacket covers
#1
Home away from home


Sorry for the duplication, I thought I was on the blog.

I was working on the water jacket covers and noticed I had a small rust hole in one corner.

I removed a brass plate that had been soldered to the back of the cover in about 5-6 spots.

It basically serves to keep water out of the cover?

Is that supposed to be there?

There was an accumulation of rust scale in between the cover and the brass plate. Odd.

My Pierce 8 has a jacket with slots which helps direct water to the cylinder bores but this one does not do that.

I am perplexed.

In the picture, bottom to top, jacket cover, brass plate rust inside.

Blasted the covers to near white. I thought I was done but there were a couple of stubborn rust spots. I hit them again and they went right thru.

I gas welded the holes with a #1 tip. Now just need to clean them up and prime them.

Ultrasonic cleaner came today.

It is a 6 gallon and works with a variety of solvents. I am using Simple Green Concentrate I got at Home Depot. Makes about 13 gallons I think and is biodegradable. The solution gets dirty in a hurry. I got it basically to clean delicate parts but I think I will use it instead of my parts washer to clean greasy/oily parts if they will fit. If you are trying to do rust removal you would need a different solution.

Seems well made for a Wuhan product. It has a digital heater and timer. Came with a basket and lid. 300 series Stainless it appears.

Here is a before and after of a cam retainer I left in for 10 min. Probably could have been longer. Like the fact it cleans to the bottom of threads, keyways and bores and around casting numbers.
