RE: Lathe for conversions
I haven't got to that part yet that one was the first cut and I have made 5-6 different ones trying to decide how I want the final ones done, I am thinking of anodizing them and then engraving them

RE: Lathe for conversions
Ken: Maybe place a few photos of the different degree wheels you have made and have a poll!! Just a idea! Capt,n

RE: Lathe for conversions
Ken, sign me up for your final version. I use to use one I had laying around for doing quarter midget B&S 5 horsers, yea kinda big for the application ....

RE: Lathe for conversions
I will be going home end of the week and will get some made . I am also converting the super tiger 2300 to gas which I should have some finished in 2 weeks ,I am planning on doing a run of 10-20 at a time, they are turnning out realy nice and light so far

RE: Lathe for conversions
hi, Yes Sign me up for the degree wheel also. heres my e-mail for when your ready. [email protected] ;)

RE: Lathe for conversions
In this engine conversion work I need a milling machine. Has anyone had experience with a Model 44991 H. Freight mini mill. Do they have what it takes to get buy with small 25-50cc engines. Also is that chuck (seems to big of a dia.) with spindal R8 taper going to work or is it best to use a collet to hold milling tools? Any help will be of great help. Thanks Capt,n

RE: Lathe for conversions
Best use a collet, a drill chuck hangs out too far and is not rigid enough...

Capt,n that machine is the same as the Micromark and a few others. Lots of information in Yahoo groups etc on them. Little Machine Shop has many links too. The R8 spindle taper is the way to go and it is standard on larger machines like my Bridgeport. Should you desire to move up some day all your tooling can be reused. You can find R8 tooling used all over Ebay etc. You can also get new tooling pretty reasonable too from Enco etc. I have R8 endmill holders as well as R8 collets. Most of the time I use the endmill holders as tool changes are quicker because you don't have to unscrew or loosen the collet from the draw bar. Just loosen the set screw and change the tool. Don't use the drill chuck to hold the tool or endmill. Endmills have a flat on them which the setscrew bites on. A collet will draw down much tighter on the tool bit than a drill chuck ever could. That machine can tilt the head left or right just like it's larger cousins. You will find though that once you tram the head in you won't use that feature much as tramming one in can be a pain until you get the hang of it. I personally use a spindle square when I need to. Simple fixture with two indicators on it. You can tram the head in about five minutes on a Bridgeport like mine. I find it easier and more accurate to use gages and blocks with either an angle vise or a regular vise to setup for angle milling. Buy a good vise and you will be happy. I have a 6 inch Kurt as well as a rebadged Bison angle vise both Excellent quality IMHO. Here is an old picture of my mill when I first got it. Runs on 3 phase so I installed a Baldor VFD drive on it and can change speeds from zero on up by pushing a button. The second picture shows the VFD drive and the vises. On the ground under the sanding machine is some of the tooling for the mill. By the way if you look close at the quill you can see an endmill holder. Takes up much less room than a drill chuck.

tim220225: Thanks for the reply. I am learning a lot about the right tooling for this type and size of machine. Tim, that sure is a nice choise of machines you have. I would love to live close by!! Is that size of mill heavy? I bet they are super hard to find. I like the looks of that multi sander and grinder combo, and the band saw. Also the airplane I like that too. Better keep your doors locked real good. No...I would not take em...but some some guys would. RCIGN1: Ralph thanks for the tip about a collet being more ridgid. I did not like the looks of the chuck on the H Freight mill...it looked to akward. The mill did have adjustable "gibs" to keep slop out. I just hope the head bearings are good quality??? In the pdf files the main bearings are ball type...I thought tapered would be better? I wish there were more small mills to choose from. Best Regards Capt,n

RE: Lathe for conversions
The mill is heavy. About 2100 pounds and made in 1956. Parts interchange all the way to today. They are easy to find but prices vary a bunch. I got it from a machine tool rebuilder in the Boston area for $2400.00 shipped to me. Holds perfect tolerance now. I priced the mini mill and by the time I got the tooling I wanted the price got pretty high do I opted for the BP. For small engine work that one would be fine. Bearings should be fine as you will take light cuts anyway. Be careful side milling as rigidity can be an issue allowing tool deflection. You could look at Grizzley machines too as they have one like you show as well as larger mills. The drill chuck is more rigid than you think but you don't want to mill with it. Oh yea, the shop is secured by an alarm. The new one will be too and attached to the house. Thanks for the compliments too.

RE: Lathe for conversions
Hey....I could use that small lathe for making fishing reels!!! Capt,n:D
|
RE: Lathe for conversions
Bigboat: That small Lathe? Will it work for winding small coils?:D

RE: Lathe for conversions
Hey guys don't pick on that poor little lathe. You have no idea what it may grow up to be. LOL

RE: Lathe for conversions
captinjohn,
This thread, you started, is just great! Your Post 231 says it all. As a wannabe machinist / mechanic/motorhead, I am humbled by what you fellows can make in your shops. Except for me, just about every male in my family was involved with things mechanical. Me, I spent my entire career in electronics. However, with my family background, I developed a reasonable ability for working with tools and machinery. In retirement, my interests tend more toward mechanics, particularly model-aircraft engines. When I started converting Ryobis, a few of the club guys said: You’ll never be able to this or that without access to a machine shop. All I have is a drill press and a few hand tools, and, yes, I send out my flywheels to be cut down. But I’ve surprised not only the naysayers, but myself as well as to what I’ve been able to do with limited ability and machinery. I don’t mean to sound as though I’m bragging, but it is truly amazing what can be accomplished in a small home workshop… if we’re just willing to try. R.C. |
RE: Lathe for conversions
ORIGINAL: captinjohn THANKS GUYS! I love this data/web links and good stuff. I read some of each already. I kinda liked what this guys said: Why I Sell Lathes Every mechanically inclined person innately yearns for a metal lathe, as soon as they find out that they exist. Maybe it comes from years of reading old Popular Mechanics magazines, or a childhood train or gyroscope. When I finally was able to get a lathe, a part of me finally felt whole, yes it sounds maudlin, but it's true, I'm a happier man for learning machining. So it's natural that I would become a bit evangelical about tools, trying to get humanity to realise the potential of their opposable thumb. Friends have learned to steer clear of technical subjects, lest I lead the conversation back to tools. Family has given up, and even visited the Starrett factory on a whim. My wife supports me so many ways, largely by not throwing me out when I drag home some great oily hunk of iron, or make her wait for hours outside a used tool dealer. I have the conviction, and only partly tongue in cheek, that if everyone had a lathe (and mill, and...) the world would change dramatically for the better. Already I have noticed that customers of mine have started doing those things they could only dream of, whether it's making their own R/C helicopter, steam engine, tobacco pipe, rocket engine or some invention so secret they won't even tell me. For those of you who have read Heidegger, I would say that they are achieving attunement with being, or maybe they're just having fun. Whatever is going on, I get the satisfaction of my customers happiness, and that's better than money. I better stop now, as I feel a tear in my eye (ha!). If you have felt that a part of you was missing, that you could make the world a better place if only you could make a precision gizmo, then by all means, get some tools! It doesn't matter if you buy them from me, only that you get them and start living your dreams. .........This is kinda the way I feel now! Capt,n :D |
RE: Lathe for conversions
Oh boy R.C. I just love those guys that say something can't be done. Usually that comes from the guys that spend big bucks on a branded engine and can't stand to admit that my "conversion" isn't as good or better as such and such brand. Personally I will go out of my way to prove them wrong if I believe in the cause. Doesn't matter the tools you have or don't have just do the best you can. Maybe if I ever retire I may just do like Ralph at RC Ignitions. If I can get this Carden Edge finished and then get settled in my new home I can get back to just flying on the weekends and machining at night.

RE: Lathe for conversions
Will be gone for some R&R for about 2 weeks! Capt,n

RE: Lathe for conversions
Well I am back from vacation. All went nice untill I hurt my right foot. Now I have to hobble around!!! Will not be able to do much....got to keep infection out and get my toes healed up. Got to go for now. Capt,n.[&:]
|
RE: Lathe for conversions
Welcome back Cap
|
RE: Lathe for conversions
Yep. Now you can get back to a slower pace working on your engines. Hey maybe this is vacation and we don't realize it... Slower pace, relaxing, hmmmm.
|
RE: Lathe for conversions
tim220225: Now its time to kick back and relax...seems like we end up driving too much trying to see everything!!!! I know I seen enough of Atlanta....twice!!! Tis good to be back ALIVE!!! Capt,n:D
|
RE: Lathe for conversions
Oh yea I know what you mean about Atlanta. Just flying in there is annoying enough but driving there is like playing Russian Roulette. I am about 5 hours from there and try to avoid driving there as much as possible. But in honesty I travel quite a bit and from what I see it is becomming the norm for society.

RE: Lathe for conversions
tstotts: Thanks for the welcome back!! Whats new? Are you going to the Toledo Expo this week-end? I would like to but have a injured foot...that HURTS......darn things happen! Best Regards Capt,n
