Looking to buy a jig for building up some Retro scratch builds. Any recommendations on jigs.

 

Rod.

I recommend the Retro Pro Backtrack.  This is an early pic.  Newer ones have a thick baseRetro Pro.jpg

Thanks for posting , Mark.
 
Below is a pic of the current model.
 
They just went up in price, $135.00 retail.
 
As Matt and Tony mentioned, the Presicion is also a very nice unit.
 
R-Geo also makes one that a lot of guys like.
 
If you plan to build 1/32nd cars, that might be the ticket for you.

The reason I like the Retro Pro is that it is straight forward, easy to setup.   Chassis building doesn't have to be complicated.

You can shop separately for custom jig wheels.  The RP has a wire bending fixture included.

I've always used them, so do your homework.  Ask around.

Jig wheel blocks are included.(upper right hand in pic)

 

The $135 I quoted is just for the building jig, as shown.

 

With the separate bending jig, the current price is $165.00.

I was thinking specifically of spec width rear jig wheels, which mine didn't include at the time.

Mike Is the Backtrack drilled for 1/8 axles or 3/32? And what is the longest wheelbase?

I'm don't entirely understand the first part of your question.

 

The pins that hold your 3/32" jig axles are lathe turned brass, and stepped (with a shoulder) to make them easier to remove.

 

In the past, I have gotten smaller diameter pins, to use with 1/8" jig axles, but they are pricey.

 

You are better off to build with 3/32" bushings in the car, and then switching to 1/8".

 

If that isn't possible, I would still use a long pc. of 3/32" piano wire, and sweat on a pc. of 1/8" brass tubing in the middle, to simulate a 1/8" axle. You might have to sand down the brass a tiny bit to fit in your 1/8" bushings / bearings.

 

Max wheel base is 4 9/16", but you can really build to any length.

 

You install either your front or back first, and then slide it up or back, between the width pins,  to solder up the opposite side in the appropriate spot.

 

As long as your chassis width has a snug fit between the pins, the front and rear will be square.

 

Or square enough for slot racing. LOL

Forget the jigs with a built in bending fixture. Sounded like a good idea but ends up impractical to use.

Sam,

Agreed.

 

Those haven't been made for 5(?) years.

Sam, Backtrack changed to separate corian plates, one for the chassis jig, another for their bending jig about two years ago. RGEO's are separate too. I don't believe Precision ever came out with a wire bender. Are their any other jig/wire bender combinations out there?

I'd like to have a jig that goes down to a 3.625 wheelbase.  Any of those setup for that? :)


She's real fine, my 409!!!

Tim,
The R-Geo should do that, or see my post #11.

Thanks Mike.
 
More information than I was looking for, but good all the same.
 
I was asking if it was set up to use 3/32 Jig axles without using some sort of shims. I got my answer but I obviously did not ask my question well.

Got it.

Correct.

You don't have to slide pcs. of tubing on the wheelbase pins to go smaller.

Sort of the opposite.

You would add a single pc. of tubing on the axle to go larger.

I have the Backtrack jig, and I use 1/8th aluminum tubing as a sleeve over the 3/32nds axle on builds

that have 1/8th bushings. Solder won't stick to aluminum, so I don't have to worry about accidentally soldering

the sleeve to the bushing. I get a little shakey sometimes these days.

I love the bending device that came with my Backtrack jig - terrific for making those "U" bends for rear axle support on my Champion Turbo Flexi chassis :)

 

A great product.

Ceramic soldering board

 

$12.....Works great!

 

Not fancy.....Must make own pins and hold downs.

 

A JOY to solder on.

 

Don't HAVE to spend $100+ to make a straight/square chassis'

 

Don't get me wrong,those fancy chassis jigs are wonderful......Just another option that  works well.

On the honeycomb ceramic plate I have, .047 piano wire works well for pins. A company down South sells pins with a taper that should fit tight in all honeycomb plates. I believe they make them in both steel & ceramic. Jewelers have used honeycomb ceramic plates for years.

Gentlemen,

 

Thanks for all the invaluable advice on building jigs. Looks as though it is between the PSC and the Retro Pro Backtrack jigs. Now I have to make my decision.

 

Thanks again.

 

Rod.
