A-34 Jigsaw Mounting Bolt

Post by Akela9 »

Hello all,

I’m working to get my dad’s 10ER back in running condition and just got an A-34 jigsaw for it. Unfortunately it’s missing the mounting bolt and spacer. Does anyone know where I can find a bolt? I’ve had no luck searching eBay. The spacer I can live without unless they’re easy to find.

Thanks!
Bill

Akela9,

Welcome to the Shopsmith Forum.

The bolt is not a typical bolt as seen in the picture below with the Spacer.

The Spacer is used when the upper arm is removed for "Sabre" Saw cutting and can be easily made if needed. The Bolt is similar to the type used for a wheel axle on, for example, some lawn mowers. I have seen them come up for sale from time to time on ebay. Do use caution if buying one labeled as a "new" replacement. I have seen one where the dimensions were not the exact sizes as the OEM ones. If I recall correctly, it required the use of washers to make it work.

Something to note about the A-34 Jig Saw for the Model 10's is there were two versions. The difference is the Lower Frame Assembly casting, the Drive Housing Cover and the number of screws (4 vs 2) to hold the Drive Housing Cover on the Lower Frame Assembly.

Below is the first version of the A-34 Jig Saw.

It is easy to see the difference of the Lower Frame Assembly. The Spacer shown on the Jig Saw Mounting Bolt above is one I made.

I you have the first version of the Jig Saw I would recommend adding something inside the Lower Frame Assembly to block the Drive Housing area from the rest of the Lower Frame. Since it is open all the way through sawdust and other debris can get into the drive area and gum things up. The second version of the Jig Saw has the Lower Frame Assembly sealed off between the Drive Housing area and the rest of the lower frame.

Akela9,

Glad to hear you found a bolt.

Sometimes a washer is helpful in tightening down the Jig Saw to the Model 10 Headstock in the Belt Cover Mounting Bolt hole. That can vary slightly due to the adjustment set screws used for leveling the Jig Saw that are on either side of the Jig Saw Frame Mounting Bolt Hole. The Belt Cover Mounting Bolt Hole on the Headstock over the Drive Sleeve Assembly has a limited depth before it bottoms out against the Spacer between the Bearings of the Drive Sleeve Assembly. I know it's clear as mud. :confused:

Hopefully you have a manual for the Jig Saw and your Model 10.
