Well here we go again, it’s been a few years since we built our first two wheel cab machine and it’s still running just fine but it’s becoming a pain when you have to keep changing sic belts as you move through the stages, so it’s going to be upgraded but that will be the second machine in our build programme.
The first machine which I will describe here is to be a 24” wide machine carrying four 8 X 3 expanding drums which will be fitted with Rez belts, these are resin impregnated which are then charged with diamond and fit onto the expanding drums. It’s going to be like heaven to move through 4 stages without having to stop each time and should improve production significantly.
Ok, back to the machine, I have put a few pictures below showing where we are at right now. I had the whole set up manufactured for me by ABC Polishing here in the UK at a cost of £150.00 plus postage, it was the only way for me to go as I don’t have the machine tools to do this myself.
It’s a 24” x 1” shaft, with a left thread on one end a right thread on the other, runs on pillow block sealed bearing, has 2,3,4 pulley fitted in the centre and there are 4 pairs of 3” diameter flanges to support the wheels. I have got some 26mm inside diameter aluminium tube with a 2mm wall which will serve as spacers between the wheels.
I have a 0.25KW motor to fit to it, which I first have to do a bit of fault finding on, suspect one of the capacitors has blown, but as I have 2 more of these that still work I should able to figure out what’s going on with it.
As this machine is going to be what I call a “clean” machine, as it won’t use water at all for cooling, I don’t need to worry about making a pan at the bottom or hoods on top so the build should be relatively quick once I get going on it. Although it will have cover to go over it to stop dust ingress when it’s not in use.
Costs so far GBP 150 for shaft and everything on it and 4 - 8X3 expanding drums about GBP237, that's about US$638
Will keep you posted on progress
Photo's below (I hope)
The complete shaft
3" diameter aluminimum flanges, there are 4 pairs of these
The 2,3,4 puley and pillow block sealed roller bearings
Threaded end of shaft with nut and washer
Cheers
