I got a highland park a-50 at auction and i'm trying to figure out the correct size belts to use for the expando drums. they are 3" wide and made by scott murray co. there is a worn out belt on one of the drums that says it's 3x25 7/32 it seems to sloppy, are the correct size belts the 25 1/8 or 25 7/3 thanks.

Hey Mark is the expando turning in the right direction? I have had a belt every now and then that was loose enough to move around. Other than that I got no clue except wait on a answer. How is life buddy? I am sawing awsy, slowwwwly, slowwww but steady getting some slabs pardner. Workin on a visit date too#

The scott murray drums use the same belts as the Lortone expandos which is the smaller one.

Does the belt stay in place when running? I had a "lapidary expert" with 20 plus years experience order some new drums from me. He called shortly after to say for 20 years he has been cursing his old drums because the belts would slide off when working. When he saw the arrows on the new drums he realized he had the old drums on backwards all those years. Of course, the amazing thing is he actually called to admit he was wrong about something. The old drums do get stiff and won't expand as far too. Scott Murray was bought out by Lortone and I had not heard they were same as Expand Lortone drums but Tony should know. He buys and sells a lot of old equipment.

I got my dad's old home made cab unit from the guy that bought his rock shop when I first got in the hobby. It had mostly split drums and one really old expanding drum. I stripped everything down, painted, installed new motor and belt. Thought it looked amazingly good for what it was. Couldn't wait to turn it on to see how smooth it ran. Forgot I had removed the belt from the expando. If you ever want to hear something scary, turn a 20-30 year old drum without a belt with a Lortone tin pan and hood around it. Thankfully the hood caught most of the shrapnel and I was not standing in front of it. I found pieces of rubber in the garage for years.

Yes John we are adults and very careful ones at that. I hear people tell these stories and in my mind I hear my grandfather telling me I am lucky to be alive after I did something stupid. Oh well grandad I am still lucky to be alive since I continue to do stupid! LOL
