DIY - Puch Dial Indicator Part#278

illenium Juergen /

This tutorial is for the tool geeks like me. If I can get the original tool for a job

for an affordable price I'll get it. If not, well, time to think and make it.

The tool we'll make here is a copy of the Puch Dial Indicator, Puch Part# 278.

Total costs to build this will be in around 20$, but you will have parts to spare.

'''Lets get started shall we?'''

Hold off grasshopper, lets talk first why there is no JB Weld or similar mentioned

here...well...we moped people love to save money and this method means you

can still use your precious dial for other things.

Now....lets get started, for real.

'''Supplies'''

1 Dial Indicator, Harbor Freight, with coupon 12-14$ (1 In. Travel Machinist's Dial Indicator, Item#623)

1 Spark plug, this one was 2.38$ at Advance Auto (Its an NGK BKR5E I had left over from a car)

1 O-Ring Assortment, Harbor Freight, 5$, pick what you like

"Tools"

-Shades...yes, nothing like porcelain in your eyes, put on your shades and look smooth while staying safe

-Dremel with a cutting disc and sanding sleeve (or other cutting tool, hacksaw works but put in some sweat)

-Drill

-Vise (makes it easier, but you can do without)

-Hammer (big or small, doesnt matter)

-Something to knock out the ceramic, like a 1/4 wrench extension, an old bolt, ...

'''Step 1'''

Put on your shades, pull out your plug, put it in the vise (or hold it if you dare). Make sure

if you put it in your vice you don't damage the threads. I leave the carton around it for

that purpose.

Now using your dremel with a cutting disc cut around the sparkplug where the porcelain ends, there

is a little lip that holds it in. Its thin metal, it wont take long. Cut around the whole plug.

'''Step 2'''

Now cut off the ground electrode. That was easy, wasn't it?

'''Step 3'''

Hammer Time!! Clamp the plug upside down into your vise. Center your extension/bolt/nail/whatever

on the electrode and give it a couple gentle tabs. It wont take much, the whole porcelain and electrode

will come out in one piece. If you hulk out here you will learn why you are wearing glasses. Be gentle.

'''Step 4'''

Back on the dremel, use the sanding sleeve to smooth out any jagged edges

you might have on the plug. We want nothing pitting the cylinder.

'''Step 5'''

Now we drill a small hole at the end of the threaded portion (up, where it doesnt

make contact with your cylinder) to avoid having compression interfere with

our funky fresh tool. Make sure there are no shavings/jagged edges after

you drill.

'''Step 6'''

Take your dial indicator, fit it with three snug o-rings and insert it into the

plug base. There will be enough friction to hold your dial in place and to

gently screw the assembly into your cylinder.

'''Congratulations Grasshopper...you got yourself a sweet tool for TDC and Timing'''

Now add an ohmmeter and you are total puch-ed out for timing :)

Ride on!!(edited)

you forgot to mention that breaking the porcelain from the spark plug is amazing for breaking windows and stuff.

fascinating and a hell of a lot of fun.

You already know what I'm gonna do when I'm back in the salvage yard.

some florida gang kids told me about it back in the 80s. they used to bust out store front windows that way to loot them.

Re: DIY - Puch Dial Indicator Part#278

Surely this isn't Puch-specific... Could be done for pretty much any, right?

Clever repurposing. Well done.

Don't forget to leave out the ninja rocks part.....

Re: DIY - Puch Dial Indicator Part#278

Yeah. No way that's going in there.

Yes, thus I'm using only o-rings. I used the dial on my drill press, trued my spoked moped wheels and will use it to set timing on other engines. Since you're using rings with my build, you can just slide out the dial and put it into another spark plug for that engine that has a different size thread. Why buy two or even more dials :)

Awww no way! Okay. it's not linked to anything so it was hard to find. i'll link it.

if you are uber thrifty you use an old tire gauge and the feelerfoot/plug bolt from the broken tool you had. the pressure marks are about .o5mm apart
