Number 1, I have ordered a new governor replacement gear from Wyatt's Musical and I would like to know if there is any special trick or tip to putting it in and Number 2, I have removed the old damaged felt from the turn table and I would like to know the best paper to use under the felt so the holes don't show thru. I would like to say that reading thru the posts I have learned a few things. Thanking you in advance.

What I did.
To replace the felt on the turn table I used a razor blade to scrap the paper off the turn table. I went to Michaels and bought a white 12 x 12 sketch pad which is the right size to cut out for an underlayment for the felt cover. I used Elmer's spray adhesive, it worked perfectly. I found a few hints on other forums. As to the fiber gear I put on a flat surface and used a small hammer to tap it on into place. It worked ok. I still don't know how tight the gears should be. I tried the record player and it was not playing very well as the needle would slow the record down, even full wound up. With this I figured the motor need rebuilt. I am willing to try anything. I saw some really high prices for a rebuild jobs. I will say it is a great challenge and should be only done if you are good with your hands. I took pictures as I took the motor apart which helped. To clean the motor I took 4 days. Its slow yes but I did one spring a day and put it together on the 4th. I did get the shaft in wrong and had to turn it around. The shaft had little hook like on it to catch the spring. I bought a large plastic bucket and pried the spring out into it. This worked well. I photo'd the unwound spring to show winding direction which was clockwise on all 3 springs. The edges were rounded so the cut factor is low. The Vaseline and graphite had hardened and I had to scrape it out and off the springs. I used paint thinner to clean the springs and enclosures. AS to repacking the springs it take a little strength to hold it with one hand and push it in with the other. I used White Lithium Grease and greased each spring before repacking it. I used gloves from Home Depot. $4.00 for 10 light weight rubberized gloves did a good job to hold the spring. To clean up with paint thinner. You could use a lot of things like kerosene or mineral sprits too. It was a great experience to try this and its a messy job. No wonder the charge so much money to do the job. The new nylon gear I go from Wyatt's for $29.00. The spring motor took a few times of winding and unwinding to spared the grease and now after about 100 years it plays and can be enjoyed.

No the one I have is a table top with the works that bolt in thru the bottom. I do have a stand up model similar to the one in the video.

Bruce,
Good for you... you now have moved into an area where a lot of collectors are afraid to go. :o ;) :!:

You replaced your own springs, cleaned the built up 100 year old gunk off the motor, replaced a gear and brought your machine back to life. I think the accomplishment of fixing something is more rewarding than the acquiring of something that already works... but that's just me. I would venture to say that the overwhelming majority of collectors would be dubious about undertaking a motor rebuild. The knowledge that you learned is invaluable for future machines, since you know exactly how they are supposed to work and you weren't afraid of tackling a messy, somewhat dangerous job. I noticed that you mentioned using various types of solvents for cleaning, as well, and didn't get all stressed out.

Always keep this in mind: when fixing something that doesn't work, don't be afraid to take it apart... it's already broken :lol: and this isn't rocket science, it is more akin to basic machine work and woodworking.

I forgot to mention that with the motor springs being a pain to reconnect to the rivet in the spring container I used a pair of sharp nose vice grips to hold the spring in place with the rivet thru the hole in the spring, then used a screwdriver to move the spring over to the locked position. I found this easier than fighting it by hand.
Curt A. thanks for the interest and kind words. The way I did look at it is the unit didn't work so if I could not fix it I could send it away to someone better then I am. I wish I could find what the tolerance should be for the gears as to how tight they should be.
