Shaft Saw Machine
- Thread starter Glenn Deneweth
- Start date
Your "Lead Shank" needs to have a shaft behind the shoulder, or the second bearing you added is doing nothing for you. You then need the handle shaft and cap screw to be hollow, so the back half can recess into it. I think this design, is more complicated, than it needs to be. I have a drawing, that I made, but I don't have a scanner. If someone would have a fax machine and a scanner, maybe they could post it for me?Glenn Deneweth said:

take another look at the pic I posted.... if you bore the round piece of aluminum very precisely, you can simply press your bearings into each end. Put 2 right next to each other on the point end. A small C-clip and a washer on the inside will keep your spring pressure, and hold the whole thing together.Glenn Deneweth said:

Sheldon, Yours looks pretty close to my design except that I used larger roller bearings and put a bronze bush, about .750" long into each bearing so as to make lateral movement easy with no binding so that I could use a light spring. My center has about 1.5" lateral movement and no or very little run-out.

Here is the design, I came up with. I guess it just proves there are many ways to get from point "A" to point "B". I think it should be smoth and solid. I am wondering, how big should a Thomson bearing be in diameter? There are quite a few, 16mm X 60" on ebay for less than $100 shipped. Would this be sturdy enough? 16mm is close to 11/16', I believe. If my design is bad, please say so, I would rather know now, than to learn a very expensive lesson. 
I also have found, drill rod comes in many specs A1, D1, etc..., which is the best?

Centers
I have decided to use Sheldon's design, slightly modified by his suggestion of adding another bearing. I am ordering the aluminum blocks today ($60 bucks) Thompson shafting is $18, that will be enough for two shanks. Just need to figure out what size bearing I need so I can determine the size of the aluminum cylinder I need. I figure around $140 bucks I should be able to build both centers. I am estimating this thing to be over a thousand by the time it's done.

I got to thinking, Sheldon's design, gets the bearing a little closer to the blade, clearance wise, which I think would lend more stiffness. I found the blocks cheaper, if you give me some time, I'll get the link for you. Have you decided on a size, for the Thomson bearing?Glenn Deneweth said:

tail stock
been reading along about shaft machines. Some interesting post.
I do a little differant for the tail stock pressure. My drive is 60 deg. and has 6 sides machined on the point. This will not allow the shafts or butts to slip. Tail stock pressure is only about 6-lbs, at most. No need to have much tail stock pressure. Very little pressure will work just fine. All you need is just enough pressure to hold the part in between the centers. When turn cutting [ profiing] it's best to have as little end pressure as possible, so you don't distort [ bow them with pressure],in a relaxed state, just as they are when they are completed.Why do something that's not nessesary, or may cause a problem down line?
No need to stress the wood. With added tail stock pressure, your taking a chance on bowing the wood, [during the cutting process], meaning it's not in it's natural relaxed position.
Not trying to fuss with anyone, just relaying on how it's done by me. Worked for me for the last 30 plus years.
Helping out I don't mind at all, have been doing it for years. This is the main reason I got this topic started on AZ.
I had a private e-mail asking why I don't I show how my stuff works? Well guys, designing and building machines, selling them, feeds us. I give a lot of free help. But I must draw the line so to speak, in some cases, when it affects my income. I surly hope you understand. Please ask, and if I can, no problem, guys. If I can help you folks, I will.

I am probably going to regret this but here goes. Blud I have been reading your posts for a couple of years now and you never have been shy in helping your fellow makers in how to build cues. When critisized from other makers for doing it you say you do it because you like to help and that competition is good. Now when asked how to build a machine your answer is a little different. Why don't you be honest with your intentions. The reason you help others is quite obvious. The more people building cues the bigger your equipment market. The makers who do not share there knowledge follow the same logic as you do Blud. There are lots of people on az offering good advice with nothing to gain than to help others, I do not think that is the case with you.blud said:

He makes no bones about it!
Blud was quite honest about not being willing to give away all of his proprietary information that he put his dollars and time into learning. Surprise, neither do most people. I didn't guard something last year and somebody else beat me to market with my idea. Hell, for all I know they may have patented it. If I take a notion to market it anyway I'll let them take me to court trying to protect their patent if they did.
Bottom line, he gives a lot and makes no bones about what he isn't willing to give away, and why he isn't. Seems more than fair to me.

I do not fault him for not giving away knowledge concerning his machines, I agree that it is quite reasonable. My point was that he seems to have a different set of principles when it comes to building cues. And I take issue with him being dishonest when stating his motives. If he wasn't selling machines I do not think he would be so willing to help others build cues.
i agree, mr bludworth has given me info on more than one occasion and he did not have to. anybody who has been in business for a while figures out that they have to set boundaries as to "how much" is "too much" to give away, whether it be drinks, nails, donuts or trade information. just my 2 cents.

"If he wasn't selling machines I do not think he would be so willing to help others build cues."
You could well be right about that part. When I gave away about $12,000 a year in sponsorships and charity donations I did it for a lot of reasons. Some pay outs made me feel good, some were purely because I felt I had little choice because of business reasons, and most were somewhere in between.
Would Blud be every bit as helpful if he wasn't selling equipment? Probably not. At the same time I see him passing out a world of information to established cue makers he is unlikely to make a dime off of.
Most of the saints are in heaven and I doubt any of us here on this board are going to qualify as saints. However, reading through all of the posts on this forum after finding it a few weeks ago, I'd say he is wasting a lot of time helping others if he is only working this forum for the dollars. He would be a lot better off spending his time cutting cues, or flipping burgers for that matter.

If he gave info away just to be a nice guy then he would help others concerning machines as well, but he doesn't. Why, because he does not profit by it. He helps people build cues because doing so can benifit him in the end by posibly bringing him a new customer. This in itself is legit, I just think he should be honest about his motives and intentions.mark smith said:

Give the guy a break. He is one of the most prolific posters on this forum. He is constantly giving good advise and answering most questions. If he draws some boundries that is his business. Most of the posters on here probably have a few secrets that they are reluctant to give up.
The thing that bugs me is that he stated that he will not share info regarding construction of machines because it is how he makes a living but he is willing to tell anybody how to build a cue. Now by helping people be cuemakers he helps himself but he isn't showing any respect to all the other makers who are doing this job full time. The full timers make a living at building cues and you do not see very many of them giving out free advice.The custom cue industry is quickly being saturated and what blud does is selfserving and in the end he will not have helped the industry. For the makers who build cues for a hobby guys like blud are a great help but for the guy who depends on his sales to make a living do you think he likes it.Mase said:
Saw Machine
You can spend lots of time making a dart board out of Bluds ass but you're not getting the machine built, and probably never will. One person already sent you a pic of what you need and then sent it again, but you have your own ideas, and thats good. There are some critical things about the machine so just build one and run it and see how it works. Change things one at a time until it suits you or step up and pay someone and get it done right the first time, or keep standing on the curb waiting for the free ride.
