Problem C&H Advantage G60

[Roger G]

I have an Advantage G60 wall mounted mat plus glass cutter.
To date have only used the mat cutting function.
Works just fine and nice and accurate.
Now trying to use the glass cutter.
Have a new carbide wheel and simply cannot get it to score the glass.
Tension at max.
Even tried a mat board behind the glass and it still does not score.
It does make a mark on a separate mat board by itself.
Oly way is to manually put pressure on the handle that is not consistent and over scores the glass.
Ideas or suggestions please.
Roger

Hi Roger and welcome to the G.

You made me cringe at "Tension at max".

Most carbide wheels will cut (score) with minimal pressure. You can damage the wheel with too much pressure or repeated cuts along the same line. The glass should be scored only once and then snapped at the score by applying pressure on either side of the score while still in the machine. The sound of the score should be faint.
Normal setup requires backing off the pressure until there is no score, then slowly increasing pressure and doing trial cuts. When the score is right the glass will snap very easily.

A few questions:
What kind of glass are you attempting to cut? Some coated products have a preferred side to cut.
Are you using any kind of lubricant on the wheel? Machine oil, lighter fluid, kerosene all work
Have you ever cut glass before?
Eye protection & Gloves?

Thank you for responding
Yes have done a fair amount of class cutting over the years with a different machine and also with HH cutters.
Have some big pieces to do and thought that using my glass cutter would be easier.
Glass is 3mm non coated
I think that something may be mismatched in the machine. Even on max the wheel hardly touches the glass and so no scoring.
I am suspicious of the Fletcher cutter wheel assembly # 02-126. Will try to get another one. Not cheap !

I don't know if you have the manual, but here's a link to one in our archive.

It looks like the technology was to insert a handheld glass cutter into the machine, and adjust with the knurled knob. I only looked at it quickly, but it didn't seem to have a specific HH cutter in mind for the job.
That may be the crux of your issue. It sounds like the cutter you have won't extend far enough in the holder to allow sufficient contact.
Doesn't mean some other cutter wouldn't work, or that you can't MacGyver one to work.

The G is a little slow with the TG weekend. Maybe by the first of the week you will get a response from someone with firsthand info.

I have that same wall cutter. The glass wheel rides in a specialized metal cartridge which slides into the opening in the rotating turret on the cutting head.

I don't think a handheld cutter would fit far enough into the opening to get the wheel to make contact with the glass. That sounds like the problem here. I doubt that Atscott has the cartridges anymore, as the machine hasn't been made in a long time. However, it might be possible to to modify a handheld cutter to fit farther into the opening by grinding down the flared part of the handle with a Dremel.

Thank you.
Yes that cartridge is exactly the same as mine complete with the locating dimple.
No not tried a HH citter - it was just a suggestion from a fellow G person.
The manual specifies a Fletcher Terry steel wheel 02-120 This is what I am using.
Alternatively the carbide one is 03-126
I believe the Fletcher 3000 uses the same wheels so are available.
Looking carefully at your photo the your wheel might protrude a tad more ? See photo of mine.
Maybe a bad batch or something along those lines.
What cutting wheel are you using ?
Interesting is that even with a mat behind the glass still no score, so something strange is going on.
Appreciate all inputs.

Hmm... My wheel doesn't really protrude that far out of the cartridge. You might have a bad wheel. The mounting clips they come in aren't very high tech, but they should fit the cartridge. Have you checked to be sure there isn't any debris in the cartridge holder keeping the cartridge from seating fully into place? And also, is there excessive play in the rotating holder on the head?
I used the regular steel replacement wheels for over 40 years, but some other folks here complained that some of the newer replacement wheels were problematic. So I invested in a carbide replacement wheel, and have been very happy with it. I actually lessened the pressure knob setting until it just gives the light score needed.
