Re: Oil filter housing for a Burtz Block

Hello Dennis,
We have about 20 Burtz blocks in my workshop that Dave Mossman bought in for various people. None completed yet due to too much other stuff going on.
But your filter block sounds...

Re: compression

Remember that compression causes the air to heat up, increasing the reading. The simple calculation from atmospheric pressure assumes isothermal (fixed temperature) conditions whereas the...

Re: Headlight bar offset to right

My roadster right hand headlight was about 1-1/2 inches closer to the radiator than the left. I took off the brackets, made both the same shape, tweaked anything else I could think of and got the gap...

Re: Has anyone heard from Purdy Swoft

Sad to hear. I always looked out for his posts. Always helpful, always sensible and always very pleasant.
His experience has already been missed.
Rest in peace Purdy.

Re: Tom Wesenberg has Passed!!

A shock to me! One always hopes for the best, but in this case poor Tom was beset with too much to survive it seems. My heart goes out to Marilee, who held his hand as he died.
He was evidently a...

Re: Remove front spring shackle?!

Place a piece of greased timber between the axle and shackle mount. Jack up the axle until, the shackle becomes unloaded by the spring, as the timber takes the spring load. Remove the shackle after...

Re: Read Main Bearing

A leak down test will determine whether it is valves or rings. Listen for the leak down air leaking from carby or exhaust or oil filler tube.
I use Mobil1 15W 40 in all my old cars. Plus I run both...

Re: The Terry Burtz 5 main bearing engine blocks are back on track.

JOHNCL, when my Burtz engines arrive soon, I will look to see if Dowty washers will do the trick.
I use these on the rear main bolts on my original engines and I think I have them under the...

Re: Rear axle nut

Wrndln, I think many repeated heating and dippings might be needed to get any usable case thickness.

Re: New Airplane Engine

Terry, 5/32 is only a bit over 1/8 inch which, when I visualize that, sounds very thin for quite large areas cast in sand. Yet even in the Victorian era, they were able to produce some amazing cast...

Re: Compression Gauge Readings

Bob, I know you know this but these comments are for non-Engineers and -Scientists who may wonder why your calculation differs from Werner's findings.
Your calculated 14.7 times compression ratio...

Re: New Airplane Engine

Terry, the power and weight statistics are very interesting. It looks like the Burtz engine is quite light without the water - 10 pounds less weight than the Continental, if you add 30 pounds for 3...

Re: Front brake arms

History, new rods still might not be long enough, depending on where else there is wear.
Sometimes a blob of weld is applied to the vertical rod end or the top adjusting rod and filed smooth to...

Re: Front brake arms

History, you need too lengthen the push rod that runs inside the kingpin, by putting a "pill" like a tiny cup shaped steel plug in the top of the actuator wedge the rod sits in. That will bring...

Re: ideas on a cheap wash tub?

Ronn,
You are forming iron acetate with the vinegar, which is dilute acetic acid. Metal acetates are soluble in water and so will dissolve in the vinegar solution. Any residues left will Wash off...

Re: ideas on a cheap wash tub?

Ronn, almost all acetates are soluble in water, so the iron/vinegar reaction compound will dissolve in the vinegar and any residuals rinse off with water. You then have a "nascent" iron surface...

Re: ideas on a cheap wash tub?

Ronn, acetic acid (vinegar) reacts with iron and zinc as in steel or galvanized buckets. It also fizzes up in contact with concrete or concrete containers and gives off carbon dioxide. In these...

Are you blowing through the valve when removed from the carby, or blowing into it while still installed and mounted on the float bowl?. If the former, like you, I cannot...
