NDK awesome job - I've been enjoying your progress. Without the wheels and any "do-overs" how much straight cost would you say you have in this?

Today I went to the local scrap yard for some stainless steel to make the holder for the water supply. It cost me $6. A little measuring, drilling, welding & poof - there it is lol. Any pic updates, NDK? What are you using to hold the water on your stainless steel stand?

Hello all. I'm new to this blog. I am going to build my own cabbing machine also. I like all of the information that is posted but I have some questions. Are the expandable drums good to use? 6 inch or 8 inch? What is the best space between wheels. Do the wheels have set screws, what stops them from spinning on the shaft. What are the best grit sizes to get? I have a 1/3 hp 1725 rpm motor and a 36" 1/2" shaft. I am ready to order some wheels and any advice would be great. Thanks. Hi, and Welcome to the RTH forum, buck88! If I were to build a machine, I would want an arbor that would support 6" and 8" wheels. I'm guessing a 1" arbor would support both. Covington sells spacers that you may want to check into. If you use 6 wheels, you may want to have the same grits on a unit such as the Diamond Pacific Genie. I use a 6" expanding drum on my Graves CabMate with diamond belts and polypads, and an 8" on the Covington with SC belts. Wheels and diamond belts for an 8" can be expensive.

Did you mean the shaft you have is 36.50 inches long? If your shaft is 1/2" diameter by 36 inches long that is NOT going to work especially with expandable drums. Many people use 1" inner-diameter PVC pipe for spacers. You can buy a couple of feet from Home Depot and cut it to any lengths you want with a pipe cutter - from experience I don't recommend trying to cut it with a hack saw.

I use a chop saw to cut 1" schedule 40 PVC for spacers. It has to be completely straight to work. A 2' piece from Home Depot buys a lot of spacers.

Jan, I have a plastic coffee tub I use for water. I just borrowed the 1 from my flat lap for now. It has a needle valve from an icemaker to control flow.

I decided I wanted a stand for my cabber, so I can move it around if need be. Went to the local scrap yard again and scored some 1" angle iron (two 12' sticks!) and 2 very nice wheels. Total was $9.00 Spent the day cutting and welding. Now I just need to cut the plywood for the shelf and clean/paint the whole thing. Thanks for looking.

Looks great! I really like the table you made for your cabber, NDK, and your water system. Are you giving your machine caffeinated coffee to drink? I like that you can wheel your machine to wherever you want to cab - while watching tv , etc... What color will you paint it? Are your plans to build a shelf underneath the table top to hold materials? I pictured a cabinet with 2 doors, with the left side to place your bucket and drain line, and the right side with a couple of shelves for lapidary supplies.

No cabbing & TV Jan, I don't watch much. For color I have a gallon of charcoal almost black I got cheap somewhere. Will work fine to keep rust away. The shelf will hold the drain bucket. It's just on a temp piece in the picture.

super nice build...but i also used a jet polishing machine to build my homemade cabbing machine 5 or 6 years ago...works great...1725 rpm...well at least till an ice storm tore everything the hell up in my rock hut last valentines day here in georgia . just posting cause maybe someone can look at the adjustable covers i made....the covers can adjust to use 4" thru 8" wheels...4" wheels shown....the covers behind the wheels adjust up and down....the top covers above the wheels with the water lip adjust in and out...mine is all aluminum....could be easily made with pvc also. water source is fish aquarium pump from 5 gallon bucket...water and grit that drains into bottom of pans diverts into another bucket....just little valves on top of covers to turn the water on and off to each wheel....not shown not around much....hope this may help someone...just ideas that me make work for myself ...kev.

Nice machine, cpdad! I like the pan, covers, and water system you designed for it. I'm sorry to hear about the GA ice storm.

Yup Chuck, it's a 1" shaft, 36" long. I believe it's 1045 bsq (bearing shaft quality). Cost me $20 & change from speedy metals. They're local so I only pay sales tax, no shipping charges. My brother-in-law is a millwright, so if I ever decide to drill the end for a polishing head, I'll disassemble it and have him do it. Does the shaft need to be 1045 steel or would regular 1018 cold finished round work? Would there be any benefit to getting a stainless shaft?

Matt, I think it depends on how long of a shaft you get. BSQ is probably your best bet. Running that speed you don't want any wobble.
Stainless would be good for corrosion resistance, but the price will be a lot more.

Does the shaft need to be 1045 steel or would regular 1018 cold finished round work? Would there be any benefit to getting a stainless shaft? Steel bar is not suitable for shafting, the diameter and straightness tolerances are too much. Stainless is best but spendy and not fun to cut threads on.
