Can anyone refer me to someone who might be able to offer guidance regarding repairing my Mark 1 table saw? I attempted to align the blade to the table by adjusting the rear trunnion on my saw, but there is not enough play in the bolt holes to take up the required slack.
I’ve removed the entire assembly from the saw, but can’t identify any obvious damage in the front or rear trunnions or the connecting rods.
I’d appreciate any help or guidance you are able to offer.
Thank you.
Hello Tom and welcome to the forum…
Can you tell me where you noticed the misalignment at first and by how much?
Who made your saw?
Thanks for getting back to me.
I purchased the saw through craig’s list about 20 years ago. The label says, “Mark 1”, but no manufacturer other than that. I’m guessing it was made in Taiwan. I did an internet search, and it seems that Mark 1 did make shop tools a one point, but information available is sketchy at best.
This is a solid tool – a basic contractor saw arrangement with the motor hanging off the back – that has worked well for me. It has a cast iron table and a 2 hp motor that I’m running at 220 VAC. The drive is a simple rubber v-belt on pulleys.
When I was making a cut, something jammed, and the bracket that holds the angle adjust shaft shattered. I’m not sure if the jam broke the bracket, of if the bracket broke and caused the jam. The bracket parts were cast metal, and I think they just broke down.
I was able to rebuild a bracket, but was unable to realign the blade to the table. It’s off by at least a ¼” to ½”.
I removed the entire under-table assembly, but can’t see anything that appears to be distorted, bent, or otherwise broken. I’m wondering if realigning the shafts that connect the front trunnion to the rear trunnion will be effective. I haven’t tried it yet, but I plan to take a look this weekend.
I’d appreciate any guidance you may be able to offer. Thank you.

The next thing I can use is pictures.
Any thing you wish to point out, use a pencil in the image.
Thanks for continuing to look at this for me. Here are some photos; let me know if you’d like more.
It looks like the import company in Kent is still operating. I don’t think it will help, but I’ll call them on Tuesday to see if parts are still available.
If you think it would help, I can put the saw in the car and bring it to you so you can see it first hand.
Thanks, again.
Tom
no problem. glad to try and help.
when you loosened the bots did they resist turning?
look to see if your trunnion bolts are bent or the bolt hole(s) are damaged…
take the trunnion of. flip it over and let’s have a look see.
That I wouldn’t mind, but, I’m in the mountains of Colorado.
do you yourself a favor and clean off all that grease w/ BRAKE CLEANER and replace it w/ dry lube. I like Tri Flow a lot.
Thanks, again.
I have cleaned the parts, but used garage door lube. I do have tri-flo, so I’ll do that next.
There’s not much that stymies me, but this has been a challenge.
I’ve been working on the saw since we came home from church, but I’m going too step away until tomorrow. I can only take so much frustration! Give me a day to take it apart again and get more pictures for you.
Thanks for staying with this.
Tom
Like I said… No problem…
I’m here all week…
I gave up!
I couldn’t see anything out of line with either the front or the rear trunnions, but I could not get the pieces to mesh. I suspect the tubes that attach the rear trunnion to the front trunnion are skewed. Ultimately, I realized it wasn’t worth my time to keep chasing this.
I found a used Delta contractor’s saw on offer-up from a man in Mukilteo (my home town) for $140. I rewired the motor to 220 VAC, attached my old cast-iron table extensions (had to re-align the holes), and tuned it up. Was able to square up the blade to 0.0025".
I recycled all the old steel and cast iron parts. Held onto the motor (for now). Twenty years ago I would have saved everything, but at this point I just want to de-clutter.
Thanks for your guidance. I appreciate your helping me get through this.
Tom
You are more than welcome… Sorry I couldn’t help…
Nice find on the Delta… that’s upgradable to 3hp and double belt sheaves. Did that to mine and never looked back.
