I located a 1 HP motor off a Craftsman 14" band saw today and the output shaft is something strange like 14 mm. Oh the joys now of locating a 14mm pulley/sheave for the output shaft. Only posting this as a warning to watch for the little things.

Please take the following only as an observation that I find interesting. It's not something I care about and is not meant to be a complaint or whining. It's certainly not directed at anyone on this forum. It's an observation only that I think others may find interesting.

The Youtube video that Matthias Wandel of Woodgears.ca fame put up of me with my thickness sander is now up over 160,000 hits. As you can imagine, I receive email on a regular basis from all over the world asking me questions about the thickness sander. I always respond to these promptly. The thing that has surprised me is that nobody (i.e. zero) has ever responded to thank me for answering their questions. The only exception to this is when they have further questions. Then they will start by thanking me for answering their first round of questions before asking their new ones.

As I said, I don't care but I am surprised as I always thank people that take the trouble to answer any questions I have sent to them and I notice that most people on this forum do the same. Am I just old and out of touch with what is polite in this age of the internet?

Pat

I usually save my thanks for after I've completed a project - like in this thread.

viewtopic.php?f=10101&t=38710&start=25

And I'll do the same after I finish this project.

All I know about life is that we as human beings will see where we're looking and if ever we do something looking for thanks it can be a mighty hard thing to see - depending, again on where we're looking. I'm thinking that sometimes when I respond there's an implied thank you if not an outright declaration of same, but I do have a general 'Thank You' in my signature because I am genuinely grateful for every bit of knowledge shared on this forum.

Thank You Pat!

Rather than hunt down a solid sheave with the specific bore diameter, you may be better off using a tapered-bore sheave (2-pc.). That would allow you to use the appropriate bushing. (I know that 14mm bushings are available.)
Of course, this means that the smallest sheave (pulley) you can use at the motor would be slightly over 3" OD, so you would have to use correspondingly larger sheave at the drum.
Bushings run $5-10 each. Nothing to be concerned about if you're saving a bunch on the motor.

Thanks so much for posting that advice Robert. I'll begin my search today for the parts you recommend. It's been a nightmare trying to resolve this 14mm issue. Again thanks very much for the advice.

Just when you thought this thread was dead, dead, dead ...

I've taken advantage of my copious free time (thanks to COVID-19) to build a thicknessing sander of my own, mostly following the Pat Hawley design (thanks, Pat!). I've got the discs cut out and ready to bore out for the axle holes. But I have two questions/comments:

1. I notice that Pat's plan called for making your own drive pulley, but somebody mentioned that pulleys with 1" drive holes are available. Would anybody know of a source for these?

2. I've decided to go with the Velcro hook-and-loop sandpaper, and there was a mention that this was available from Woodmaster. I went to their site, but I'm not sure about what their products are.

Is this the stuff to attach to the drum itself?

https://www.woodmastertools.com/shop/ac ... ro-mats-3/


And is this the actual sandpaper stuff, with the corresponding velcro?

https://www.woodmastertools.com/shop/ac ... -150-grit/

And I guess I should ask about other suppliers for the Velcro sandpaper and base.

Finally, I want to thank all the people who have participated in this thread. It's been a real learning experience.

1” bore pulleys are available at McMaster Carr, Tractor Supply, and Northern Tool, off the top of my head.

I got my hook and loop paper from Klingspor.

I got my Velcro for the drum at Lowe’s.

Never asked Pat a question but did build a thickness sander based on seeing his.

Thanks Pat, if you’re listening.

I built one of similar design several years ago. The discs were just pressure fit over the shaft. Very tight, had to pound them on and glued them to each other as I went. No way they would ever spin. I also weed pre finished flooring for the table top. I made my dust collector/shield out of 1/4” plexiglass. I like being able to see both sides as the wood passes through. I put a dust collection port top center and it works very well. As mentioned earlier, small steps to remove material is the key.
