Making new diaphragms for Disston, D0-101, Fuel meter.

[Lewis Brander]

Still looking for cement:

To Al Smith: Thanks for the info. I'll try and check them out.

I recieved a reply from anchorrubber and the glue or cement that they sell is made by Bostik, product number 1142. Any one heard of this stuff? Mike at anchorrubber seens to think that smaller tubes or containers should be had locally, so will have to see if I can find some around. I also sent Cyber Bond an email, no reply as yet. A friend of mine suggested a Duro bond product, that is sold at the local Walmart, will have ot check it out. Thanks to all for your suggestions. I haven't given up as yet and hope to find something that will work. Lewis.

Rubber Cement:

Just an update: Today I bought some rubber adhesive that has many uses. Resistant to gas, oil, alcohol and most solvents. I buffed 2 pieces of the Buna Nylon material and applied a bit of the cement, let it set for a few minutes and stuck them together and applied pressre to bond. It takes about 6 t0 8 hrs to cure, depending on the temperature. So about 8:30 tonight I'll give them a tug and see if they hold. If they do I'll put the pieces in some gas/oil mix and see if they come apart by morning. If they hold, I'll be the happiest member here. I may just get the old Disston running again. Let you know what happens. Lewis.

An update fo my last thread.

Well, I glued 2 pieces of the Buna Nylon material together and let them cure. I then put them in some gas oil mix over night to see if the glue held. Took them out of the mixture and dried them, gave them a little pull to see if they would separate. They would if I pulled on them hard enough. So I then put them back in the gas/oil mix. It's been several days and I checked them this morning, again. They are still bonded together, so guess mabe this will work. I'm now waiting for my .031" thick Buna material I need to complete making the diaphragms. Hopefully it will be here, UPS today. Once I get those diaphragms made and the saw back up and running I'll post some pictures of the saw runnig again. Thanks for all your help and suggestions. Lewis.

Lewis,

You've got more determination than I have. I'd have given up on this saw a long time ago. I'm going to remember what you're doing here.

To cbfarmall:

I just have a stubborn streak. If I get an idea to do something I'll usually keep at it untill I know there is no solution. As I've said before the saw belonged to a good friend of mine, who was like a second grandfather to me. So I guess I'll try anything, within reson, to see if I can keep it going. I just hope the old crank seals don't give out in the mean time, because of this gas we all have to use. I'm sure they're made of a more rubber base material. But if I have to, I'll remove them, measure them up and see if replacement can be found also. I look at this as a challange, something to be thought about and solutions found to try and repair a problem, Ha, but still wish the saw had used say a Tollitson type carb on it. I have found a fellow who has some factory information on these old fuel meters. When he gets the chance he says he'll copy and email me what he has, when his business calms down a bit for the summer. Can't wait to see just what he has. His family sold those old Disstons, during the late 40's and early 50's. He still has some of those old saw, in original shape and in runnig conditon. I'm also trying to get him to send a gas tank that has the original engine decal on it to a fellow, so that he can copy and possibly reproduce it. After I get this saw back to runnig condition, I hope to get the decals to finish off the restoration. Just wish me luck and thanks for your reply. Lewis.

Another update:

Well have made the basic part of the diaphragms and now just recieved the .031" thick Buna Nylon material from UPS. Going to my basement, where I work on my saws and make the so called "buttons" to glue on the diaphragms. It's about 4:35 PM so by 5 PM I'll have the diaphragms done and glued together. They'll have to cure about 6 hrs, then I'll place them in some gas/oil mix and check them in the morning. Hopefully by this time tomorrow the old Disston will be running. Will let you know. Lewis.

Hang in there

Lewis; I'll say this,at least you have the "stick to iteve ness" that it takes for restoration work.Not many of us old diehards left.I once made a worm gear drive,for an old{1903] drillpress,that all the tool and die makers,told me was not possible[ I am an electician,by trade],nonsense,any thing made by human hands,can be duplicated.Hang in there,you will get it.

Hi Lewis,
Are you going to start selling these reproduction diaphrams? I guess you might have to be an A.S. sponsor to do that. I sure hope they work!

 

[Lawn Masters]

Anything that was made by man can be reproduced. Lewis you're a very determined individual with this saw, I'm glad to see I'm not the only one that doesnt quit just because its not new.
Just because its an antique doesnt mean it cant be repaired or duplicated.

To All following this thread:

Yesterday I cut the so called buttons and glued them to the diaphragm material and held them untill they bonded together. I then let them sit overnight between 2 pieces of glass with a small light bulb suppling some heat to help them cure. This morning I assembled the old fuel meter and did some cleaning on the saw ( removing some old black silicone gasket maker). I then reassembled the saw, fueled her up and as of 3:00 PM this afternoos, THE OLD SAW IS BACK TO RUNNING!!!!!!!!!! Had to do some adjusting to the fuel meter, but she's running better than before. I have taken some pictures and had my wife, Holly, take some while I was running the old saw. Just wish I had a log handy to try her out on. As soon as I get them developed and scanned onto this computer I'll post some of them. I had one fuel leak, but think I have it repaired. Will know if an when I start her back up again.

To Al Smith: Hanging in there or just being stubborn, sometimes pays off. I would have kept going untill I found some sort of solution. Thanks for the encouragement.

To Scott Mueller: I have some of that Buna Nylon material left and I suppose I could make more replacement diaphrams, but no I don't plan on getting into any big time reproduction. I still have the templates or patterns I used to make them, if you need a couple someday, give me a shout. So far the diaphragm in the bottom of the old fuel meter ( with the neddle valve) is working just fine. That will be an other project if it ever goes. Hopefully it will last for all the running I plan to do with that saw. But if it goes, I'll find a way to repaire or remamufacture that one too. I've done the most research of what saws I own mostly on the old Disstons. I just wish I could find or afford to buy a few more of them, in particular the old 2 man saws. The KB and DA models. They have exsisted around here in the past, but have not been able to scare any of those saws up as yet. Have had offers from various places, but the pictures I've recieved of some of the saws looked a little scary and the prices they wanted and shipping was way out of my budget. I'll hang in there and eventually I'll own one of those saws yet. Hey, did you ever try that "O" ring trick to stop the fuel leakage around the impeller shaft? Did you ever get the rewind repaired on your saw?

To oldsaw-addict: You must have read my signiture at the end of my post. I agree, just because its old, doesn't mean it can't be made to run, with a little TLC.

I've taken some pictures and if I can get them developed tomorrow I'll post them. Thanks to all for your advice, encouragement and patience. Ive learned a lot from this site and try to give back a little knoledge on what I've been able to accomplish on repairing my old saws. Everyone take care. Lewis.

PS. My wife is dropping off the film tonight and hopefully I be able to post some pics tomorrow if they don't have to send it out to have the film developed. Take care. Lewis.

A few pictures:

Here's a few pictures of what I've been up to. Be patient it may take me awhile to post them all. Thanks. Lewis.

The caption for the picture is pretty self explanitory, but I'll add a comment or two as I go along. The first pic is of the saw with the fuel meter removed.

This is of the disassembled fuel meter.

Another picture:

A pic of the old moulded rubber diaphragms. It seemed the more I handled them, the more they fell apart.

Another picture:

This pic is not to clear, but a pic of the 2 completed diaphragms ready to install back in the old fuel meter.

This is me starting the old Disston, D0-101.

Another picture:

This is the old saw running at near WOT. I have the fuel meter start run lever set a little on the rich side, since she hasn't been run in awhile. I'm running MX2T Moble 1 at 32/1 mix.

Another picture:

Here she is jusst idling. Is sure good to have her back to running condition again. If you look close you can see the smoke from the exhaust.

Here she is back in her rightfull spot on the shelves.
