A Few Basic Precision Tools

Hey GRUMPY, I need a few basic tools to measure bearing clearances and tools for installing a cam, etc, and suggestions?
(and yeah, I'm not swimming in cash, so please take that into account!)

you tend to get what you pay for in the level of quality in precision tools,
keep in mind you don,t always require the best quality tool to do a very nice build,
but you seldom get great results with low quality tools either,
its generally best to get upper mid range tools
but there are bargains, make a detailed list of your goals,
and the parts and tools you need and ask questions,

don,t guess or assume anything.
and you certainly don,t need the very best tool quality to build an acceptable and durable engine,

if you look over this web site you'll see its set up to answer questions and help guide you,
in engine assembly and avoiding problems.
I'd recommend you get a sturdy engine stand

reading as many links related to any questions you have as you can!

you can use all the precision measuring tools you may have but the truth is always evident in cross checking with plasti-gauge

Precision measuring tools

I’m looking for the best quality precision tools on a limited budget (i.e. I don't want to pay $300 for one mic). I plan on building the occasional small- & big-block Chevy (more than one, less than 1000). Names that come up on the limited results I’ve found on the web include Starrett...

lining up oil feed holes in bearings shells

I just got an e-mail asking what to do if you find that the blocks oil feed passage holes don,t line up exactly right with the holes in the oil feed holes in bearings shells? paint, marker etc. tends to wash off, you really should lightly die stamp the main caps...

assembling and installing connecting rods/pistons

look closely at the connecting rods one edge of the main bearing are is beveled noticeably more than the other that beveled side faces away from the rod its paired with because it matches the slight radiased bevel of the crank journal many builder class pistons are designed to go in, in either...

matching parts and a logical plan

I just had a rather long and detailed discussion with a guy who it was all too obvious ,was basically just, trying to get me to give him a detailed list of engine components to build his engine. one of the main secrets , too building a really effective combo is to match the engine and drive...

I use both micrometers and snap gauges and cross check with plasti-gauge
and yes when you compare the crushed width of the plasti-gauge youll find it rarely falls as an exact match to the bar chart tape that is packaged with it so you can judge clearance based on crush width

as a general rule you select .001 bearing clearance for every inch of bearing journal diameter,
Rod bearings 0.002 - 0.025" , side clearance 0.010 - 0.020"

Main bearings 0.002 - 0.003" for most engines ( 0.020-0.025 bearing clearance on small blocks, .025-.027 bearing clearance is about ideal, on big blocks ), 0.005 - 0.007 crankshaft end play

almost all starter tool kits are loaded with tools you seldom use to build up the tool numbers in the kits
yet many are still a good value, but remember you'll need a few auxiliary accessory kits for tools like screw drivers ratchet wrenches and a couple ,wire cutters drill bits, pliers,socket extensions and swivels,
frequently used tools like a decent 1/2" chuck electric drill, and vise grips, 12" dial caliper, multi meter,etc.
you can certainly use a couple of soft tool bags as they are far easier to carry , in your car or store than the cheap plastic or flimsy metal boxes that come with most starter tool kits

after a while your sure to find you have accumulated a few tools ,
or small and expensive parts,
that did not come in higher quality protective boxes,
you don,t want to lose or damage these components,
letting them bounce around under other tools or parts unprotected,
smaller or precision tools like
rod bolt stretch gauges,
snap ring pliers and replaceable tip sets
milling machine bits,
drill bits,
louis tools,
spring height gauges
feeler gauges
, micrometers ,
depth mics ,
adjustable push rods,
spare fuel injectors
carb parts and jets
etc.
parts like ceramic magnets
carb gaskets
and electrical connectors,
(SENSOR PIGTAILS)
engine DOWELS
valve keepers/valve retainers
oxygen sensors and various other sensors
must be stored in protective boxes

you might find you keep those tools in a rust free compartment in your tool box
and you might want to store them in a shallow plastic snap lid box on a sheet of felt lightly sprayed with WD40
for that use the boxes used to store fishing lures with the removable dividers removed have proven useful
as they are thin enough and small enough to easily sit in tool chest drawers

solid fixture here in the forum
I keep hundreds of those type boxes I keep everything in them from reloading dies to PVC pipe fittings to nuts and bolts every brand size and color and they are stacked and labeled I also have 30 Stanley fat max tool boxes to separate tools that I carry for work ones for solder and braze ,sheetmetal , A/C tools it makes it easier to grab what you need for the job
