Re: Shoptask 1720

Hey, I'm looking at page 28 of the Grizzly manual I linked to and looking at the pictures you posted and now I have to wonder if your column height is adjustable after all. Does your round ring rotate when you loosen the broken lock lever???

Re: Shoptask 1720

My machine is considerably different. I think yours is much closer to the Grizzly G4015 (ie: single motor machine.) Hmmm. I see Grizzly no longer has the 4015 manual on their website, but they do have the newer G4015Z info: Parts: http://cdn2.grizzly.com/partslists/g4015z_pl.pdf Manual: http://cdn1....

Re: Shoptask 1720

Yes, Harold, there are adjustment screws on the operator side of the tailstock, but one looks to be buried and barely visible under the thick gob of paint. Be advised that it is possible there are two screws, one behind the other. The one closest to the gib adjusts the clearance and the second, if ...

Re: Shoptask 1720

Threading, on that machine, will require the use of dies. I doubt it came with a compound originally. Later models of this style grafted the tool post onto a crappy milling vise. The vise is on a swivel base and the post is mounted to the moving jaw. As a compound, it's OK. As a milling vise, it sti...

Re: Shoptask 1720

The broken lever handle is probably threaded in -- a left-hand drill bit is usually sufficient. Or a regular drill bit and an easy-out.

Re: Shoptask 1720

The vise alone is probably worth $50, so maybe you got $300 worth of tooling and he threw the machine in for free. ;-)

Just don't let Harold see that photo of the chuck key left unattended in the chuck.

Re: Shoptask 1720

Thanks Todd. I am still trying to get my head around the "column Height" issue mentioned twice now... This pic from Shopmaster website shows a "Shopmaster 1720 with what looks like an adjustable height column? http://www.shopmasterusa.com/content/15-history-3-in-1-machine-cnc I'm going by memory of...

Re: Shoptask 1720

There were a number of variants bearing the "1720" model designation. Early ones were pretty limited in capability, and suffered from various shortcomings that contributed heavily to the poor reputation of the 3-in-1 format. Later models sported improvements and upgrades to make it more usable. I ha...

Re: Knuth DBF-800

Oh, ok, that's the typical Chinese 3-in-1. Did you get the set of change gears with it? You need them for threading.

Re: Knuth DBF-800

My preference would be spray the light rust with Evaporust, cover with paper or shop towels soaked in same rather than the abrasive approach. A light scrub with the damp shop towels will get rust out of any pits. Watch for hardened grease in any bearings. Other than that, I wouldn't presume to offer...
