Correcting Height Alignment
Good Afternoon All:
Finally got most kinks out of my alignment problems with replacement parts from Homier. Headstock, saddle, cross-slide and compound assemblies were replaced. Accuracy is dramatically improved, although new problem is headstock is 0.015" lower than the tailstock. What would be the preferred method of correction? Should I shim the headstock, and if so, is there a difference in brass vs. steel shims? Or, should the tailstock base be carefully cut down? Replacement of the parts has improved accuracy greatly, but due to this height difference, I get a slight chatter and taper 0.0055" on a 9.5" length of stock. I attribute the chatter to the height difference as the tool advances toward the headstock. If you advise that shimming the headstock is the preferred method, I would also consider upgrading the spindle bearing to ABEC-3 units, in contemplation of eventually using a 4 or 5" 4-jaw chuck on this lathe. Have any of you changed these bearings? If so, any notable difference in how the lathe sounds/operates? Any suggestions/recommendations would be greatly appreciated. Regards, Nick |
Re: Cap. of 4 jaw chuck?
Rick's got a great idea. The same thought occurred to
me when I was last making a backing plate. Maybe I'll try that on this next one.

for it. I have a nice 1" thick piece of 5" diameter 12L14 that I am going to use. I read about Rick Kruger's adjustable chuck plate and was kind of intrigued by that idea. Perhaps that's a good fallback design if one tries to make a non-adjustable chuck and ends up with too much runout? What do you think? Flint ----- Original Message -----

Re: Cap. of 4 jaw chuck?
Hi, Flint. I bought the 5" chuck, but have not had
time yet to make the backing plate. For those who are interested, the following link has lots of info on chuck options for the minilathe, and a link to the page on how to make a back plate for chucks larger than 3" diameter: Frank Hoose --- bflint <bflint@...> wrote: CFSHOUSE:

I have a 7x12 (old version Homier). The current Homier and Grizzly are pretty much the same unit. Several of us with this lathe have recently bought a 5" 3 jaw chuck from J&L Industrial, on sale for $64. Part no. is PCC-05000 The chuck jaws still seem to clear the ways of the lathe at max extension. The specs say the external jaws can grip an OD of 110 mm or about 4.33 inches. There is a 4-jaw 5" chuck made by Bison that a minilathe owner has and is happy with. But, it's a bit more expensive, at approx. $150. If you need a 4 jaw though, this might be a good way to go if you want max capacity with the 7x12. One word of caution. You will have to find or make an adapter plate to mount a 5" chuck on the mini lathe. There are several how-to web pages to guide you through this. Makes a good project!

Cap. of 4 jaw chuck?
cfshouse <[email protected]>
Hi,
I am debating on which lathe to buy the 7x12 or 9x20 and was wondering what the largest cap. that a 4 jaw chuck will hold in either of these 2 lathes? I think that the 7x will be large enough though I will have to purchase the 4 jaw for it. Also what is the largest recommended size chuck for the 7x? Is the speedway as good a lathe as say the Grizzly or HF? Thanks for any info, cfshouse |
Re: a few questions
Very nice, John. I love the camlock tailstock - it's
a huge timesaver and just a lot more pleasant to work with than the wrench & nut arrangement. I checked out your website & noticed the info on microscopy. My dad bought microscopes for me and my sister for Xmas when I was about 10 which began a lifelong fascination with them. When I was in HS I bought an oil immersion scope with a mechanical stage from Lafayette Radio. It took weeks to arrive and I remember coming home from school every day looking for the much awaited package. When I finally got it I was really excited - spent many happy hours with it. I sold it some years later when I was newly married and needed money. Sometime in the next 2-3 years I hope to buy a good used microscope and get back into it.

Hi Frank,
Thanks for the comment. Sorry I wasn't clear about the handle location. I did put the handle in the position shown on your site - it seems more convenient there - but used Rick's mechanism for actuation. I have since posted a picture on my site: I like the cam concept a lot and will try to use it to make a variation of Vikki Ford's saddle lock. It seems as if this would allow locks on both sides of the saddle, actuated by one lever, without too much difficulty.

Re: 4-jaw
As long as it is one of the new Homiers with 6 holes
in the spindle it is a direct fit. Some of the early Homiers only have 3 holes in the spindle.

Re: 4-jaw
Should fit just fine, they're essentially the same machine with a
different paint job. If your Homier doesn't have 6 holes in the spindle, you'll have to drill them - the HF 4-jaw chuck mounts with 4 studs. (Frank Hoose's site has either the drilling template or a link to one {memory is a memory tonight!}) ;-) Roy --- In 7x12minilathe@..., "kf4zgz <kf4zgz@n...>" <kf4zgz@n...> wrote: Does anyone know if the 4-jaw chuck from HF..priced at $49.99...fits the Speedway 7x12 from Homier?in stock!

Re: a few questions
I recommend learning to grind your own tools. You
will find that you can grind many specially shaped tools to solve all kinds of problems. It's not hard - just buy about 20 blanks and dive in. Here are some links that may help: Frank Hoose --- "kf4zgz <kf4zgz@...>" <kf4zgz@...> wrote: Hi gang! __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful.

First lathe purchase
jackasspkd <[email protected]>
Hi everyone. I am a new member and this is my first posting on this
site. I have been bitten by the lathe bug and Im thinking of buying a Homier (Speedway) 7X12. I figure since most of you do mods and upgrading to your lathes than I should start out with the cheap one and add, as I need, the accessories and modifications. Does this seem like the right road to take or should I spend a couple of more hundred dollars for one of the other ones. The only thing keeping me from ordering is, I cant make up my mind which one to get. Jack |
Re: a few questions
John <[email protected]>
Hi Matt,
I'm new to lathes too so this may be a case of the blind leading the blind, but as a first project I built Rick Kruger's tailstock camlock, see: lstock/ This was reasonably easy to build from scrap, I used old bolts for raw material and a piece of brass rod I found for the lever. I built the version with the lever behind the tailstock, drilling a hole through the web, an option Rick suggested. By having the cam shaft go through the web it is constrains the vertical shaft from twisting so a large washer was adequate as the contact for the under side of the bed; Rick used a more elaborate contact with a setscrew to keep the vertical shaft from twisting. Since I don't have a 4 jaw chuck (it's in the mail...) I put a shim between one jaw and the part as an offset to make the cam. Overall, it's simple (once you see Rick's design), fun to make and it works great. John --- In 7x12minilathe@..., "kf4zgz <kf4zgz@n...>" <kf4zgz@n...> wrote: Hi gang! |
