Head Stands for the Bridgeport Mill
Here is another great idea on how to expand the use of your Bridgeport knee
mill, its a set of adjustable risers used to support irregular shaped
cylinder heads, John Edwards @ Costa Mesa R&D Automotive Machine Shop
describes the way that they are used. (949) 631-6376 John Edwards is the

Home made Line boring machine video # 4
This is my home made Line boring tool tested out today June the 6 taking
cut work good I m using the 36 inch bar have a 72 inch bar also made 2
for quick line up made the cutting bits i use 1/2 in square carbide bit and
turn it on the
lathe to make it 1/2 in round

Blueprint 106 - Cylinder Bore Inspection
We're close to the end of the 100-level series. In this video I show you
how to measure the cylinder bores using 2 different tools. I compare the
results and illustrate what to look for to determine whether or not your
engine is in-spec.
The block I'm using is a 6-bolt turbo
4g63 from early '92. It has 150,000 miles and this video also serves as a
testimony for the durability of Mitsubishi's cast-iron solid-decked Sirius
I engines. This engine will be cut for a new set of pistons, so these
measurements are needed to determine what size pistons I need to get.
.030" is as far overbored as you should ever take a 4g63. Boring larger
than that will take too much off the side clearances between the cylinder
walls and result in compromised strength from hot spots. The only time
you'll ever need to cut a bigger hole is when an imperfection prevents you
from using the pistons you have, or if you're changing to a larger piston.
If you cut the block to its service limit, you have no room to fix an
imperfection should one develop... so it's best to cut as little as you can
get away with. Boring a cylinder .020" over does not significantly
increase its displacement.

Homemade 4 Cylinder Carburetor Synchronizer/Manometer
An extended video of my homemade manometer with detailed explanations and
demonstrations of it in operation. Very inexpensive yet very accurate. I
used Snapple bottles which worked fine, but if you can get taller bottles
that would be better as it gives you more time to fix a severely
out-of-sync cylinder before a bottle runs dry. You'll notice my design
links all 4 cylinders together to give you true comparison across all 4
Since it's been asked: if you get air in the reservoir line simply
blow/suck on one of the cylinder lines until all air bubbles are gone; just
like if a bottle goes dry, etc.
And for the carburetor adapters, you can make your own (see my comment in
the comments section) or buy them here:
Here's a list of required materials:
4 Glass bottles
4 Rubber Stoppers
4 plastic 'tees'
20'-25' clear tubing
4 intake port adapters (specific to your bike make/model)
Tip: put the stoppers in the freezer for a while before trying to drill the
holes for the tubing and it will drill much cleaner.

Engine Building with Rog - Hone and Measure - HD
Here are some engine building videos from my old man, Rog. He explains the
honing process and how to measue with a dial bore gauge. We are working on
a Ford small block (351 Windsor) with a .030 over-bore and it wll have a 4"
